    New heat-flow values for seven sites in the Anadarko basin, Oklahoma, were determined using high-precision temperature logs and thermal conductivity measurements from nearly 300 core plugs. Three of the sites are on the northern shelf, three sites are in the deep basin, and one site is in the frontal fault zone of the northern Wichita Mountains. The heat flow decreased from 55 to 64 mW/m2 in the north, and from 39 to 54 mW/m2 in the south, due to a decrease in heat generation in the underlying basement rock toward the south. Lateral lithologic changes in the basin, combined with the change in heat flow across the basin, resulted in an unusual pattern of thermal maturity. The vitrinite reflectance values of the Upper Devonian-Lower Mississippian Woodford formation are highest 30-40 km north-northwest of the deepest part of the basin. The offset in highest reflectance values is due to the contrast in thermal conductivity between the Pennsylvanian "granite wash" section adjacent to the Wichita uplift and the Pennsylvanian shale section to the north. The geothermal gradient in the low-conductivity shale section is elevated relative to the geothermal gradient in the high-conductivity "granite wash" section, thus displacing the highest temperatures to the north of the deepest part of the basin. Apatite fission-track, vitrinite reflectance, and heat-flow data were used to constrain regional aspects of the burial history of the Anadarko basin. By combining these data sets, we infer that at least 1.5 km of denudation has occurred at two sites in the deep Anadarko basin since the early to middle Cenozoic (40 ?? 10 m.y.). The timing of the onset of denudation in the southern Anadarko basin coincides with the period of late Eocene erosion observed in the southern Rocky Mountains and in the northern Great Plains. Burial history models for two wells from the deep Anadarko basin predict that shales of the Woodford formation passed through the hydrocarbon maturity window by the end of the Permian section in the deep basin moved into the hydrocarbon maturity window during Mesozoic burial of the region. Presently, the depth interval of the main zone of oil maturation (% Ro = 0.7-0.9) is approximately 2800-3800 m in the eastern deep basin basin and 2200-3000 m in the western deep basin. The greater depth to the top of the oil maturity zone and larger depth range of the zone in the eastern part of the deep basin are due to the lower heat flow associated with more mafic basement toward the east. The burial history model for the northern shelf indicates that the Woodford formation has been in the early oil maturity zone since the Early Permian.

    Three major lithofacies have been identified within the Morrow (Pennsylvanian) and Springer (Pennsylvanian-Mississippian) units, in core from 30 drill holes ranging from the Oklahoma Panhandle to the southwestern portion of the Anadarko basin. The study included inspection of ~6,500 ft of core, examination of ~100 thin sections, and a scanning-electron-microscope study of butts of the material used for thin-section preparation. The lithofacies identified are (1) fluvial-influenced coastal, which includes the deltaic facies described by Swanson (1979), (2) tidal-influenced nearshore, and (3) mixed, which shows mixed tidal and nontidal marine influence. Our interpretation is supported by the investigations of Moore (1979), Haiduk (1987), and Swanson (1979). The fluvial-influenced coastal facies is restricted to the northwestern (Panhandle) portion of the Anadarko basin.

    The Anadarko Basin of western Oklahoma is a WNW-ESE elongated trough filled with of Paleozoic sediments. Most models call for tectonic activity to end in Pennsylvanian times. NASA Shuttle Imaging Radar revealed a distinctive and very straight lineament set extending virtually the entire length of the Anadarko Basin. The lineaments cut across the relatively flat-lying Permian units exposed at the surface. The character of these lineaments is seen most obviously as a tonal variation. Major streams, including the Washita and Little Washita rivers, appear to be controlled by the location of the lineaments. Subsurface data indicate the lineaments may be the updip expression of a buried major fault system, the Mountain View fault. Two principal conclusions arise from this analysis: (1) the complex Mountain View Fault system appears to extend southeast to join the Reagan, Sulphur, and/or Mill Creek faults of the Arbuckle Mountains, and (2) this fault system has been reactivated in Permian or younger times.

  4. Anadarko Basin conodont studies

    1989-01-01

    Preliminary analysis of early Paleozoic conodonts from the subsurface within and adjacent to the Anadarko basin demonstrates their utility in stratigraphic and thermal evolution studies in the basin. More than 100 samples from 30 drill holes produced conodonts that can be correlated with faunas known from rock sequences exposed along the southern flanks of the basin. For the Middle Ordovician to Devonian, extant biozonations and/or recent published literature based on Oklahoma surface sections allow good biostratigraphic correlation into the subsurface and often allow testing of physical correlations. In contrast, conodonts from the Arbuckle Group (Lower to Middle Ordovician) are less well known. Faunas from the upper half of the group are documented only in unpublished theses, and published faunas are in need of restudy and revision. However, this limited information, along with work in progress in Oklahoma and data from carbonate platform facies elsewhere in North America, still permit correlations into the subsurface with the promise of increasingly improved resolution.

  5. Evolution of overpressured and underpressured oil and gas reservoirs, Anadarko Basin of Oklahoma, Texas, and Kansas

    Departures of resistivity logs from a normal compaction gradient indicate that overpressure previously extended north of the present-day overpressured zone. These indicators of paleopressure, which are strongest in the deep basin, are mapped to the Kansas-Oklahoma border in shales of Desmoinesian age. The broad area of paleopressure has contracted to the deep basin, and today the overpressured deep basin, as determined from drillstem tests, is bounded on the north by strata with near normal pressures (hydrostatic), grading to the northwest to pressures that are less than hydrostatic (underpressured). Thus the pressure regime in the northwest portion of the Anadarko Basin has evolved from paleo-overpressure to present-day underpressure. Using pressure data from drillstem tests, we constructed cross sections and potentiometric maps that illustrate the extent and nature of present-day underpressuring. Downcutting and exposure of Lower Permian and Pennsylvanian strata along, and east of, the Nemaha fault zone in central Oklahoma form the discharge locus where pressure reaches near atmospheric. From east to west, hydraulic head increases by several hundred feet in each rock formation, whereas elevation increases by thousands of feet. The resulting underpressuring of the aquifer-supported oil and gas fields, which also increases from east to west, is a consequence of the vertical separation between surface elevation and hydraulic head. A 1,000-ft thick cap of Permian evaporites and shales isolates the underlying strata from the surface, preventing re-establishment of a normal hydrostatic gradient. Thus, the present-day pressure regime of oil and gas reservoirs, overpressured in the deep basin and underpressured on the northwest flank of the basin, is the result of two distinct geologic events-rapid burial and uplift/erosion-widely separated in time.

  6. Regional geologic characteristics relevant to horizontal drilling, Woodford Shale, Anadarko basin, Oklahoma

    Horizontal drilling in the Late Devonian-Early Mississippian Bakken Formation of the Williston basin has spurred new interest in other black shales as primary hydrocarbon reservoirs. The Late Devonian-Early Mississippian Woodford Shale, which is similar in some respects to the Bakken Formation, is a major source of oil and gas in the Anadarko basin of Oklahoma and could prove to be a significant reservoir rock as well. The three regional geologic characteristics of the Woodford discussed here are of likely importance to horizontal drilling programs, although direct relations to drilling strategy cannot be developed until empirical data from horizontal tests become available. First, the Woodford Shale is composed of three distinct depositional units (the upper, middle, and lower informal members) with different physical and geochemical properties. Second, a paleotopographic high that was rising before and during Woodford deposition divided the Woodford Shale into northeast and southwest depocenters. Third, Woodford depositional patterns are overprinted by thermal-maturity trends shaped primarily by differential burial of the Woodford during Pennsylvanian and Permian time. The Woodford Shale northeast of the forebulge is generally immature to marginally mature, whereas its thermal maturity southwest of the forebulge ranges from mature to postmature with respect to oil generation. A formation resistivity of about 35 ohm-m approximates the updip limit of oil-saturated Woodford Shale from which free oil might be produced from fracture systems.

  7. Depositional model, dolomitization, and porosity of Henryhouse Formation (Silurian), Anadarko basin, Oklahoma

    Beardall, G.B.

    1987-08-01

    The Upper Silurian Henryhouse Formation, which is part of the Hunton Group, is a major hydrocarbon reservoir in the Anadarko basin. Three basic lithofacies are present in the Henryhouse, based on sedimentary structures, lithology, fossil content, and fabric relationships. These facies, represented in general by massive lime mudstone with diverse fauna, burrowed dolowackestone/packstone with mainly crinoids, and massive to laminated dolomudstone with fenestral fabrics and sparse fauna, are inferred to represent subtidal, intertidal, and supratidal environments, respectively. These facies comprise a vertical sequence that represents regressive deposition. The Henryhouse consists of several of these sequences. The Henryhouse commonly is partly or completely dolomitized in western Oklahoma. Three stages of dolomitization were documented: (1) penecontemporaneous hypersaline dolomite occurring as brownish, hypidiotopic rhombs concentrated in the supratidal and intertidal facies, (2) mixed marine and freshwater dolomite occurring as white rims around preexisting hypersaline dolomite, and as subhedral, white rhombs in vugs and molds, and (3) deep-burial vug, mold, and fracture-filling saddle dolomite. Production in the Henryhouse is generally from porous zones in dolomite. However, lithofacies reflecting depositional environments in which they were formed are equally important in porosity development.

    1989-01-01

    Investigations of 6,500 ft of core and -100 thin-sectioned core samples from 30 drill holes from the Oklahoma Panhandle to the southeast part of the Anadarko basin, Oklahoma, have led to the recognition of three depositional facies of the Springer and Morrow Formations of Mississippian and Pennsylvanian age, as recognized by geologists working in the subsurface of the Midcontinent region. Lithofacies include (1) fluvial-influenced coastal (FIC), (2) tidal-influenced nearshore (TINS), and (3) mixed, which shows mixed tidal and non-tidal marine influence (MT/NTM). The FIC facies is restricted to down-hole depths of 4,400-8,000 ft; the TINS facies is recognized only between down-hole depths of 4,000 and 18,000 ft. Thin-section study of sandstone indicates that quartz arenite is the most common rock type in both the FIC and TINS facies. Subarkose is present, but not common, in the FIC facies. Sublitharenite is moderately common in the TINS facies. Calcite skeletal fragments, mainly of brachiopods and crinoids, are more abundant in the FJC facies than in the TINS facies. The mixed facies includes quartz arenite, subarkose, and sublitharenite. Iron-bearing carbonate cements are observed in rocks of all three depositional facies. Porosity is typically 12,000 ft. Thin films of bitumen have inhibited the effects of diagenesis in some samples. Fractures are identified in core samples, but are rare in thin sections. Porosity is due primarily to dissolution of glauconite, clays or clayey matrix, and some framework grains, but many dissolution pores are partly or completely filled with various clays, and only microporosity remains.

    The Berlin gas field in Beckham County, Oklahoma, was discovered in 1977 and is the largest Atoka (Pennsylvanian) hydrocarbon accumulation in the Anadarko basin. It is an overpressured reservoir 15,000 ft (4572 m) deep and occupies a surface area of 41 mi/sup 2/ (106 km/sup 2/). The reservoir rock consists primarily of recycled, detrital Arbuckle Dolomite (Cambrian-Ordovician), and contains ultimate recoverable reserves of 242 to 362 bcf (6850 to 10,250 x 10/sup 6/ m/sup 3/). The Arbuckle Dolomite and limited exposures of Precambrian granite rocks were eroded from the Amarillo-Wichita mountains during the Atokan and were deposited as a terrigenous, sandy dolomite clastic wedge adjacent to the uplift. During the late Atokan, the Elk City structure was uplifted and subaerially exposed in the vicinity of the northern limit of the dolomite clastic wedge. The detrital dolomite on the structure was concurrently eroded and recycled northward as a shallow marine fan delta. Subsequent recrystallization destroyed the detrital depositional texture and created the present intercrystalline porosity. The deep Elk City structure consists of an upthrust block bounded by the late Atokan unconformity which is genetically associated with the Berlin fan delta. The present relief on the upthrust block and overlying anticlinal folds was formed during post-Atokan growth of the structure. The Berlin field provides a model of a large, localized detrital deposit derived from uplift and erosion of a prominent structure, and it is an example of the potential for large detrital stratigraphic traps around the perimeters of prominent structures containing crestal unconformities. 14 figures, 1 table.

  10. Thermal maturation by vitrinite reflectance of Woodford Shale, Anadarko Basin, Oklahoma: discussion

    SciTech Connect

    Katz, B.J.; Liro, L.M.

    1987-07-01

    Cardott and Lambert (1985) proposed a single linear relationship to predict vitrinite reflectance values as a function of depth for the Woodford Shale within the Anadarko basin. They tested their proposed relationship by comparing published nitrinite data with that predicted by the regression. Several measured reflectance values proved to be significantly less than those predicted by the regression. Cardott and Lambert implied that the lack of correlation is due to analytical and interpretive error, the need for some refinement in the regression, and the presence of the thermal anomaly within the basin. The authors believe, however, that the observed discrepancies may be more fundamental, particularly those observed in deeper samples where much of the variability occurred. A single regression relating reflectance to depth of an individual unit does not take into consideration natural geologic variation within the basin. These geologic variations may be manifested in the geothermal gradient (past and present), burial history, or both (Tissot and Welte, 1984).

    This experiment was designed to determine the types and amounts of information valuable to petroleum exploration extractable from ERTS data and the cost of obtaining the information using traditional or conventional means. It was desired that an evaluation of this new petroleum exploration tool be made in a geologically well known area in order to assess its usefulness in an unknown area. The Anadarko Basin lies in western Oklahoma and the panhandle of Texas. It was chosen as a test site because there is a great deal of published information available on the surface and subsurface geology of the area, and there are many known structures that act as traps for hydrocarbons. This basin is similar to several other large epicontinental sedimentary basins. It was found that ERTS imagery is an excellent tool for reconnaissance exploration of large sedimentary basins or new exploration provinces. For the first time, small and medium size oil companies can rapidly and effectively analyze exploration provinces as a whole.

  12. Genetic sequence stratigraphy of upper Desmoinesian Oswego limestone along northern shelf margin of Anadarko basin, West-Central Oklahoma

    Derstine, T.P.

    1988-01-01

    The Pennsylvania Oswego limestone (upper Desmoinesian) in the vicinity of the northern shelf break of the Anadarko basin contains stratigraphic sequences and associated depositional facies that were controlled by eustatic variations in a slowly subsiding basin. Core descriptions, detailed well-log correlations, and facies maps of Oswego limestone in Dewey and Custer Counties, Oklahoma, supplemented by seismic data along dip profile, define at least two principal stratigraphic sequences separated by regional unconformities. In this area, oil and gas have been produced from phylloid algal-bank deposits that formed at the shelf margin. The algal-bank deposits that contain vuggy and moldic porosity are bound northward by wackestones of shelf facies and southward by tightly calcite-cemented packstones that formed on the seaward margin in relatively high-energy environments. The detailed well-log correlations that consider genetic units illustrate the evolution of these carbonate and locally clastic deposits along Oswego shelf-ramp-basin profiles as a consequence of sea level oscillations. Repeated succession of upward-coarsening shelf wackestones, algal-bank deposits with fringing packstones and scattered terrigenous clastics, and basinal shales are a depositional system tract associated with sea level lowstand. This lowstand system is capped in one of the principal stratigraphic sequences by a thin shale that reflects an episode of rapid relative sea level rise and flooding of the Oswego carbonate shelf. Black shales deposited during this rapid flooding event form a problematic downlapping unit, because terrigenous sediment was evidently supplied from both the Oklahoma-Kansas area to the north and the Wichita-Amarillo high to the south. Highstand carbonate facies system are not present in the shaly cyclic sequences indicating drowning or backstepping of carbonate sources.

    The fluvial meander belt containing the Old Woman sandstone served as a conduit for clastics transported into the Anadarko basin. Mappable for a distance of more than 30 mi (48 km), sand bodies characterizing this system average 0.5 mi (0.8 km) in width and attain maximum thicknesses of 50-70 ft (15-20 m). Channel and point-bar sandstone facies display a fining-upward sequence and sharp basal contact, as inferred from gamma-ray and resistivity logs. Sandstones of the Old Woman fluvial complex overlie the laminated shales and silts of the penecontemporaneous flood-plain environment. These flood-plain deposits are underlain by crinoidal wackestones and packstones deposited in the subtidal regime. Encroachment of the fluvial complex into a marine setting is interpreted from this sequence. Thin flood-plain deposits and lack of shallow marine clastic sediments suggest rapid advancement. Quartzitic and petrologically mature, the Old Woman sandstone is fine grained, with small-scale troughs and laminations, and a few mudstone rip-up clasts. Diagenesis has altered the mineralogic composition mainly by siliceous and carbonate cementation. Porosity is secondary, resulting from dissolution of various metastable constituents. The Old Woman sandstone was established as a hydrocarbon reservoir in the early 1960s, and sporadic development continued for years. The present-day petroleum market has prompted a resurgence in drilling activity owing to the economic viability of this reservoir. Successful wells are concentrated in newly discovered meander-belt bends; however, the elusiveness of this fluvial system challenges today's exploration geologists as it has for the past quarter century.

    This investigation was undertaken to determine the types and amounts of information valuable to petroleum exploration that are extractable from ERTS data and to determine the cost of obtaining the information from ERTS relative to costs using traditional or conventional means. In particular, it was desirable to evaluate this new petroleum exploration tool in a geologically well-known area in order to assess its potential usefulness in an unknown area. In light of the current energy situation, it is felt that such an evaluation is important in order to best utilize technical efforts with customary exploration tools, by rapidly focusing attention on the most promising areas in order to reduce the time required to go through the exploration cycle and to maximize cost savings. The Anadarko Basin lies in western Oklahoma and the panhandle of Texas (Figure 1). It was chosen as a test site because there is a great deal of published information available on the surface and subsurface geology of the area, there are many known structures that act as traps for hydrocarbons, and it is similar to several other large epicontinental sedimentary basins.

    The U.S. Geological Survey, using a geoscience-based assessment methodology, estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in the Anadarko Basin Province; this assessment includes the Las Animas arch area of southeastern Colorado. The province is at a mature stage of exploration and development for conventional resources. Mean undiscovered continuous resources are estimated at 79 percent of oil, 90 percent of natural gas, and 81 percent of natural gas liquids in the province.

    1989-01-01

    The Upper Devonian and Lower Mississippian Woodford Shale is a black, organic-rich shale that is a major hydrocarbon source rock in the Anadarko basin. With the onset of oil generation, nonconductive hydrocarbons begin to replace conductive pore water in the Woodford, and formation resistivity increases. Crossplots of formation resistivity versus either vitrinite reflectance (RO) or Lopatin's time-temperature index of thermal maturity (TTI) define two data populations that represent immature shales and shales that have generated oil. The midpoint of the resistivity zone marking the transition between immature and mature shales is -35 ohm-m. The onset of appreciable oil generation in the Woodford Shale of the study area occurs at maturity levels of RO near 0.57% and of TTI between 33 and 48.

    Located at the core of the Sooner Trend on the northeast shelf of the Anadarko Basin is the Enid Embayment. Using regional mapping and production trends it is possible to expand the idea of an Enid Embayment to a concept of two basins, a northern shallow basin and the main basin to the south. From a terminology point of view, it would also be appropriate to map a single basin with a northwest trending arch cutting across the shelf of that basin. The evidence for this concept is most pronounced in the Pennsylvanian producing trends by can also be inferred as early as Siluro-Devonian Hunton time. There also clearly exists the presence of a through going linear on the Landsat interpreted data suggesting the existence of a deep seated, basement fault system underlying the arch which separates the two basin axes. Shoreline trends in the northern basin are very pronounced because the basin was very shallow, and the shelf edges were very low dip. Therefore, small changes in sea level caused large movements in shoreline locations. The mapping of shoreline locations through time in the shallow basin can produce a better understanding of shoreline deposits in the deep basin and assist in the understanding of producing fairways and their potential extensions. Although the concept is not new, the recognition and interpretation of two basin concept can be of assistance in exploring for, and finding, the more elusive fields that remain in this mature area.

    1988-01-01

    Natural gas production in the Anadarko basin comes from three geographically separated areas that can be differentiated by age of reservoir and by inferred nature of organic, thermal origin of the gases. In the central basin, non-associated gases are produced mainly from Upper Mississippian and Pennsylvanian sandstones. Gas samples are from reservoirs as much as 6588 m deep. Gases become isotopically heavier (??13C1-values range from -49.8 to -33.2???) and chemically drier (C2+-values range from 1-33%) with increasing level of thermal maturity. Gases were generated mainly from interbedded shales with type-III kerogen during the mature and post-mature stages of hydrocarbon generation. Deviations from the trend are due to vertical migration and mixing of gases generated at different levels of thermal maturity over the past 250 Myr. In the giant Panhandle-Hugoton field, non-associated gases are generally produced from Permian carbonates at depths of <900 m. Gases display little compositional variation (mean ??13C1-value is -43.2???, mean C2+-value is 14%). Because organic-rich, mature source rocks are not present in the area, gases probably were generated in the central basin from Pennsylvanian or older source rocks during the mature stage of hydrocarbon generation. This interpretation implies migration over distances as much as several hundred kilometers. In the Sooner Trend, associated gases are produced from Silurian, Devonian and Mississippian carbonates at depths as great as 2950 m and were generated from type-II kerogen during the mature stage of hydrocarbon generation. Associated oil usually correlates with extracts of the Upper Devonian and Lower Mississippian Woodford Shale. Gases are isotopically lighter (mean ??13C1-value is -43.9???) and chemically wetter (mean C2+ value is 14%) than those derived from type-III kerogen at an equivalent level of thermal maturity. ?? 1988.

    The research project investigated various geochemical aspects of oils, suspected source rocks, and tar sands collected from the Anadarko Basin, Oklahoma. The information has been used, in general, to investigate possible sources for the oils in the basin, to study mechanisms of oil generation and migration, and characterization of depositional environments. The major thrust of the recent work involved characterization of potential source formations in the Basin in addition to the Woodford shale. The formations evaluated included the Morrow, Springer, Viola, Arbuckle, Oil Creek, and Sylvan shales. A good distribution of these samples was obtained from throughout the basin and were evaluated in terms of source potential and thermal maturity based on geochemical characteristics. The data were incorporated into a basin modelling program aimed at predicting the quantities of oil that could, potentially, have been generated from each formation. The study of crude oils was extended from our earlier work to cover a much wider area of the basin to determine the distribution of genetically-related oils, and whether or not they were derived from single or multiple sources, as well as attempting to correlate them with their suspected source formations. Recent studies in our laboratory also demonstrated the presence of high molecular weight components(C{sub 4}-C{sub 80}) in oils and waxes from drill pipes of various wells in the region. Results from such a study will have possible ramifications for enhanced oil recovery and reservoir engineering studies.

  2. Narrow annulus cementing in the deep Anadarko Basin

    1995-03-01

    With the widespread use of tubingless completions and narrow annulus liners now employed in the Anadarko Basin the applicability of conventional cementing placement techniques and cement systems has been brought into question. The narrower annuli necessitate the use of a more dispersed cement to impart acceptable friction pressure. Excessive friction pressure may lead to formation breakdown, lost circulation and potential well control problems. If lower friction pressures can be achieved higher pump rates should be attainable which may improve fluid placement efficiency. The dispersed slurry must still maintain acceptable fluid loss control and solids suspension properties. These parameters are critical in narrow annulus cementing since high fluid loss and/or sedimentation is much more likely to cause annular bridging than in a conventional annulus. As in most cases, it is desirable to use a slurry with a rapid and predictable transition from a fluid to set state. It must be recognized that mud removal is critical in a narrow annulus because a small volume of contaminated fluid can occupy a large interval in the annulus. To address these issues a study was initiated to develop a methodology for cementing in this environment.

    Natural-gas production in the Anadarko basin is from three geographically separated areas that can be differentiated by age of reservoir and by inferred nature of thermal origin of the gases. In the central basin, nonassociated gases are produced mainly from Upper Mississippian and Pennsylvanian sandstones. Gases become isotopically heavier (δ13C1 values range from -49.8 to -33.2 ppt) and chemically drier (C1/C1–5 values range from 0.74 to 0.99) with increasing level of thermal maturity. Gas samples are from depths as much as 21,600 ft. Gases were generated mainly from interbedded shales with type-III kerogen during the mature and postmature stages of hydrocarbon generation. Deviations from the trend are due to mixing and migration of gases generated at different levels of thermal maturity over the past 250 m.y. In the giant Panhandle-Hugoton field, nonassociated gases are generally produced from Permian carbonates at depths 13C1 values range from -46.4 to -39.9 ppt, C1/C1–5 values range from 0.69 to 0.96). Because organic-rich, mature source rocks are not present in the area, gases probably were generated in the central basin from Pennsylvanian or older source rocks during the mature stage of hydrocarbon generation. This implies migration over distances as much as several hundred miles. In the Sooner trend, associated gases are produced from Silurian, Devonian, and Mississippian carbonates at depths as great as 9,600 ft and were generated from type-II kerogen during the mature stage of hydrocarbon generation. Associated oil correlates with extracts of the Upper Devonian and Lower Mississippian Woodford Shale. Gases are isotopically lighter (δ13C1 values of -47.3 to -40.6 ppt) and chemically wetter (C1/C1–5 values of 0.67 to 0.99) than those derived from type-III kerogen at an equivalent level of thermal maturity.

    Focuses on the drilling of the deep Springer Sands in the Cyril basin 65 miles southwest of Oklahoma City. Anadarko is a high cost, unstable price area, where reserve risk offers some quantifiable downside. Increasing costs of drilling and the threat of lower gas prices have driven down leasehold costs to 40-50% of 1981 costs. Suggests that independents should attempt to improve technology and reduce costs; and combat government regulations and excessive taxes that significantly affect exploration and production.

    Modeling and interpretation of aeromagnetic data across the transition between the Anadarko basin and the Wichita uplift in the vicinity of the scarp on the Meers fault (Fig. 1) constrains structural relationships and lithologic contrasts at this boundary. We digitized aeromagnetic data from the map based on a detailed survey flown in 1954 (U.S. Geological Survey, 1975). The flight lines for this survey were oriented east-west, spaced 0.25 mi apart, and flown 500 ft above the ground. The digitized data were gridded using a minimum-curvature gridding program (MINC; Webring, 1981) and plotted as a color-shaded relief map using an unpublished program written by M. W. Webring. The color-shaded relief map was shown in the Anadarko Basin Workshop poster session. Figure 2 is a generalized contour map made from the digitized data, using the unpublished program CONTOURS, written by R. H. Bracken, R. H. Godson, and M. W. Webring.

  6. Ground water in the alluvial deposits of the Washita River between Clinton and Anadarko, Oklahoma

    The Washita River alluvial deposits between Clinton and Anadarko primarily are fine-grained sand and clay, and lesser amounts of coarser-grained material. These deposits range in thickness from 0 to 120 feet and average about 64 feet. Well yields range from only a few gallons per minute in some of the sandy clay beds to more than 240 gallons per minute (gpm) in sections where a higher percentage of coarse material has been deposited. Test pumping indicates that wells yielding 60 to 150 gpm could be developed in about 50 percent of the valley and wells yielding more than 150 gpm in about 10 percent. The higher yields generally occur along a relatively narrow buried channel where the alluvial deposits are thicker and coarser than the surrounding alluvium. This area is not discernible at the surface and must be located by test drilling.

    The Anadarko basin is a large, deep, two-stage Paleozoic basin (Feinstein, 1981) that is petroleum rich and generally well explored. The Anadarko basin province, a geogrphic area used here mostly for the convenience of mapping and data management, is defined by political boundaries that include the Anadarko basin proper. The boundaries of the province are identical to those used by the U.S. Geological Survey (USGS) in the 1995 National Assessment of United Stated Oil and Gas Resources. The data in this report, also identical to those used in the national assessment, are from several computerized data bases including Nehring Research Group (NRG) Associates Inc., Significant Oil and Gas Fields of the United States (1992); Petroleum Information (PI), Inc., Well History Control System (1991); and Petroleum Information (PI), Inc., Petro-ROM: Production data on CD-ROM (1993). Although generated mostly in response to the national assessment, the data presented here arc grouped differently and arc displayed and described in greater detail. In addition, the stratigraphic sequences discussed may not necessarily correlate with the "plays" of the 1995 national assessment. This report uses computer-generated maps to show drilling intensity, producing wells, major fields, and other geologic information relevant to petroleum exploration and production in the lower Paleozoic part of the Anadarko basin province as defined for the U.S. Geological Survey's 1995 national petroleum assessment. Hydrocarbon accumulations must meet a minimum standard of 1 million barrels of oil (MMBO) or 6 billion cubic feet of gas (BCFG) estimated ultimate recovery to be included in this report as a major field or revoir. Mapped strata in this report include the Upper Cambrian to Lower Ordovician Arbuckle and Low Ordovician Ellenburger Groups, the Middle Ordovician Simpson Group, and the Middle to Upper Ordovician Viola Group.

    1983-06-01

    Successful cementing in the deep Anadarko Basin, as in other deep producing provinces, requires meticulous attention to detail. Problems encountered during cementing operations include high temperature, high pressure, gas migration, and lost circulation. At times, these problems stretch the bounds of technology in rheological control of drilling mud and cement slurry. Although successful cementing techniques for Anadarko Basin deep wells present particular challenges, the principles involved also apply to other deep producing provinces. Deep well programs vary from one area of the Anadarko Basin to another. The variation is a function of the pressure encountered while drilling.

  9. Crestal unconformities as indicators of clastic stratigraphic traps: genetic relation of Berlin field and Elk City structure, deep Anadarko basin

    SciTech Connect

    Lyday, J.R.

    1988-02-01

    The Berlin fan-delta gas reservoir in the deep Anardarko basin was deposited during the late Atokan (Pennsylvanian) as a response to the initial uplift and erosion of the Elk City structure. During the late Atokan pulse of the episodic Pennsylvanian orogeny in the south-central US, abrupt epeirogenic uplift and brittle deformation created an interregional unconformity on positive areas around foreland and cratonic basins. The Elk City structure within the deep Anadarko basin originated as a distinct, subaerially exposed upthrust-block during the late Atokan tectonic event. A crestal unconformity developed on the emergent upthrust block concurrent with its uplift. Terrigenous, detrital Atoka dolomite, originally sourced from the Arbuckle dolomite (Cambrian-Ordovician) of the Amarillo-Wichita uplift, was eroded from the upthrust block and recycled northward as the Berlin fan-delta. Today, the Berlin recrystallized, recycled detrital dolomite fan-delta is a large 41 mi/sup 2/ overpressured gas reservoir with 242-362 bcf reserves at 15,000 ft. The Berlin field is genetically related to the late Atokan crestal unconformity of the Elk City structure, and is an example of the association of crestal unconformities and clastic stratigraphic traps. Such stratigraphic traps originated in marine environments proximal to active structures that have become subaerially exposed. With adequate seals and favorable structural position, detrital deposits recycled from local uplifts can form significant stratigraphic traps. Such stratigraphic traps can occur in compressional, extensional, and diapiric regions.

    Oklahoma is one of the most seismically active areas in the southern Mid-Continent. From 1897 to 1988, over 700 earthquakes are known to have occurred in Oklahoma. The earliest documented Oklahoma earthquake took place on December 2, 1897, near Jefferson, in Grant County. The largest known Oklahoma earthquake happened near El Reno on April 9, 1952. This magnitude 5.5 (mb) earthquake was felt from Austin, Texas, to Des Moines, Iowa, and covered a felt area of approximately 362,000 km{sup 2}. Prior to 1962, all earthquakes in Oklahoma (59) were either known from historical accounts or from seismograph stations outside the state. Over half of these events were located in Canadian County. In late 1961, the first seismographs were installed in Oklahoma. From 1962 through 1976, 70 additional earthquakes were added to the earthquake database. In 1977, a statewide network of seven semipermanent and three radio-telemetry seismograph stations were installed. The additional stations have improved earthquake detection and location in the state of Oklahoma. From 1977 to 1988, over 570 additional earthquakes were located in Oklahoma, mostly of magnitudes less than 2.5. Most of these events occurred on the eastern margin of the Anadarko basin along a zone 135 km long by 40 km wide that extends from Canadian County to the southern edge of Garvin County. Another general area of earthquake activity lies along and north of the Ouachita Mountains in the Arkoma basin. A few earthquakes have occurred in the shelves that border the Arkoma and Anadarko basins.

  11. Quantitative seismic reservoir characterization of tight sands (granite wash) play at Stiles Ranch field in the Anadarko Basin, Texas (USA)

    The main objective of this study is to conduct quantitative seismic reservoir characterization study of the Granite Wash (Marmaton-tight sand) play at Stiles Ranch field in the Anadarko Basin, Texas (USA). The proposed methodology incorporates seismic petrophysics, rock physics, Amplitude Variation with Offset (AVO) analysis and seismic pre-stack simultaneous elastic impedance inversion. In addition, it utilizes geostatistical technique to improve the reservoir property estimation and quantify uncertainty in seismic lithology and fluid prediction. The general objective encompasses several more specific goals to study: well data conditioning and prediction of essential petrophysical properties (e.g., porosity, permeability and saturation), and their relationship to the elastic properties. Due to the multidisciplinary nature of seismic petrophysics, only three core aspects are focused on that cover the desired objectives: 1) porosity modeling, 2) shear wave prediction, and (3) fluid substitution. The rock types are characterized by Rock Physics Diagnostic (RPD) approach conducted on well log data calibrated with core data and thin sections. The Granite Wash reservoir elastic properties are upscaled from log to seismic scale using Backus averaging to obtain a more coarsely (upscaled) sampled data set equivalent to the seismic scale. Anisotropy parametric (epsilon, gamma and delta) log curves are estimated consistent with seismic measurements using rock properties, seismic velocity and clay volume (Vsh) as a function of depth. The reservoir elastic properties are related to both the depositional environment and burial history through rock physics depth trends as function of depth. Furthermore, based on the practical aspects two separate inversion approaches; AVO and Elastic Impedance (EI) are evaluated prior to their application to real seismic. Various AVO derived attribute volumes such as intercept (A), gradient (B) and reflection coefficients (scaled Poisson's ratio, fluid factor, and sum of reflection coefficients) are quantitatively used to help identify prospective hydrocarbon zones. The accuracy of various EI formulas is discussed and the most optimal one is used for pre-stack simultaneous elastic inversion. Finally, post-stack and pre-stack simultaneous elastic inversions are comparatively analyzed on AVO compliant re-processed data for fluids prediction. Pre-stack simultaneous elastic inversion is preferred over post-stack inversion which provides more promising results. The net-to-gross (N/G) ratio is estimated using a quantitative method calibrated with log derived seismic rock properties. Finally, a probabilistic approach is applied to derive lithofacies information from inverted seismic attributes and respective well log data to quantify the uncertainty in the seismic lithology prediction (hydrocarbon saturation). Lithofacies probability maps derived from log and seismic attributes provide a better prediction of reservoir producing and non-producing zones.

    1989-01-01

    Organic geochemical analyses of 104 crude oils and 190 core samples of dark-colored shales from the greater Anadarko basin show three major oil types which generally correlate with reservoir age and source-rock age. Analyses include C3-C30 whole-oil gas chromatography, C10+ saturated-hydrocarbon-fraction gas chromatography, and carbon stable isotopes (ppt relative to PDB) of saturated (sat) and aromatic (arom) hydrocarbon fractions. Three samples from Middle Ordovician Simpson Group reservoirs are "typical" Ordovician oils (type 1), having strong odd-carbon predominance in the C13 to C19 n-alkanes, containing little or no acyclic isoprenoids, an δ13C values of -33.9 ppt (sat) and -33.7 ppt (arom). Oils from Silurian to Devonian and Mississippian reservoirs (type 2) show little or no odd-carbon predominance in the n-alkanes, a regular decrease in abundance of n-alkanes with increasing carbon number, pristane/phytane ratios (pr/ph) of 1.1 to 1.5, and δ13C values of -30.6 ppt (sat) and -30.1 ppt (arom). Oils in Pennsylvanian reservoirs (type 3) have the greatest amounts of C15+ hydrocarbons, are isotopically heavy (-27.5 ppt [sat] and -26.4 ppt [arom]), have methyl-cyclohexane as the most abundant hydrocarbon, and have pr/ph values from 2.0 to 0.9. Oils from the Kansas shelf area of the Anadarko basin are similar to the Anadarko oil types except that they have only traces of toluene and no detectable benzene. The relative abundance of toluene in the C7 hydrocarbons systematically decreases with distance from the depocenter of the basin. The aromatic compounds are removed by water-washing, and hence could have been lost by contact with progressively greater amounts of formation water during long-distance migration. The lack of thermally mature source rocks in southern and central Kansas supports this hypothesis.

    Subsurface temperature and thermal gradients along a north-south cross section through the Arkoma Basin and the Oklahoma Platform in southeastern Oklahoma were estimated from 345 bottom hole temperatures from 199 oil and gas wells. The average geothermal gradient in the southern part of the basin near the Ouachita Front is 20C/km, exceeds 30C/km in the middle part of the basin, and is 24C/km on the Oklahoma Platform to the north. Drill cuttings obtained from 11 oil and gas wells were used for 843 thermal conductivity measurements. Thermal conductivity data, corrected to in situ conditions, were used to estimate heat flow. Estimated heat flow (20%) in the deep part of the Arkoma Basin near the Ouachita Front is 35-40 mW/m2 and increases systematically northward to 60-65 mW/m2 on the Oklahoma Platform. Average heat production, estimated from gamma ray logs, is 2.3 0.2 ?W/m3 for basement rocks underlying the Arkoma Basin and 2.8 0.1 ?W/m3 for basement rocks in the Oklahoma Platform area. Numerical models show that heat refraction from the less conductive sedimentary rocks (1.6 W/mK) of the Arkoma Basin to the more conductive crystalline rocks (3.0 W/mK at 25C) of the Oklahoma Platform and the Ouachita Mountains accounts for about 5-10 mW/m2 of the observed 20-30 mW/m2 decrease in heat flow from north to south. Changes in crustal heat production related to compositional changes and crustal thinning account for another 5-15 mW/m2 of the observed heat flow change. If the remaining 0-20 mW/m2 difference in heat flow is attributed to heat transport by topographically driven groundwater flow, the average basin-scale permeability of the Arkoma Basin and the Oklahoma Platform can be no greater than 10-15 m2. Results of this study are not generally supportive of theories which invoke topographically driven regional groundwater flow from the Arkoma Basin in Late Pennsylvanian-Early Permian time (290 Ma) to explain the genesis of Mississippi Valley-type lead-zinc deposits, paleothermal anomalies, and regional diagenesis in the North American midcontinent.

    Numerous types of environmental data have been collected in the upper Washita River basin in southwestern Oklahoma. However, to date these data have not been compiled into a format that can be comprehensively queried for the purpose of evaluating the effects of various conservation practices implemented to reduce agricultural runoff and erosion in parts of the upper Washita River basin. This U.S. Geological Survey publication, 'Digital atlas of the upper Washita River basin, southwestern Oklahoma' was created to assist with environmental analysis. This atlas contains 30 spatial data sets that can be used in environmental assessment and decision making for the upper Washita River basin. This digital atlas includes U.S. Geological Survey sampling sites and associated water-quality, biological, water-level, and streamflow data collected from 1903 to 2005. The data were retrieved from the U.S. Geological Survey National Water Information System database on September 29, 2005. Data sets are from the Geology, Geography, and Water disciplines of the U.S. Geological Survey and cover parts of Beckham, Caddo, Canadian, Comanche, Custer, Dewey, Grady, Kiowa, and Washita Counties in southwestern Oklahoma. A bibliography of past reports from the U.S. Geological Survey and other State and Federal agencies from 1949 to 2004 is included in the atlas. Additionally, reports by Becker (2001), Martin (2002), Fairchild and others (2004), and Miller and Stanley (2005) are provided in electronic format.

  15. Geologic provinces of Oklahoma

    The geologic provinces of Oklahoma are mainly the product of tectonics and attendant sedimentation of Pennsylvanian age. Most boundaries are structural; thus, the provinces map is a generalized tectonic map. Permian and post-Paleozoic strata tend to mask those structures, but most of those strata have been removed by erosion, except in the Anadarko Basin and the Wichita Uplift provinces. The location of most of Oklahoma`s oil and gas resources are either influenced by, or are the direct result of Pennsylvanian tectonics and sedimentation patterns. Therefore, the present study also defines provinces in the subsurface on the basis of geological criteria. The authors have attempted to use the originally published names for the recognized provinces. However, we have also used the most geologically correct names, i.e., Nemaha Uplift, Nemaha Fault Zone, and Central Oklahoma Fault, in lieu of Nemaha {open_quotes}Ridge.{close_quotes} Oklahoma is separated into five major uplifts and five major basins. The Gulf Coastal Plain is not included in this study because it is a veneer of Cretaceous cover that masks significant structures. Faults are the most common boundary element. Although their precise age commonly is known only approximately, their geographic location is less controversial, except in detail. Stratigraphic/structural boundaries are based on less precise geological information. The major example of a surface stratigraphic/structural boundary is the southwestern limit of the Ozark Uplift in eastern Oklahoma. Stratigraphic/structural boundaries in the subsurface are commonly based on structural or isopachous contours from well or geophysical data, or on a structural trend, as well as the experience of the authors. Basement structure is preferred. An example is the boundary that separates the Marietta Basin from adjacent geologic elements.

    Red Oak gas field, with ultimate reserves of greater than 2 TCF methane, is the largest field in the Arkoma basin. As a result of dynamic tectonic evolution of the basin during the Atokan, sandstone reservoirs display significant contrasts in reservoir characteristics. The basal Atokan Spiro sandstone is a quartz arenite deposited in southward prograding deltas on a tectonically stable shelf. Geologic events associated with evolution of the Ouachita-Arkoma tectonic system influenced the Spiro reservoir. Most important among these were (1) fracturing of the Spiro into normal fault blocks, (2) facies selective diagenesis, (3) liquid hydrocarbon accumulation, (4) thermal degradation of hydrocarbons of methane, and (5) hydrothermal quartz cementation below hydrocarbon-water contacts. The middle Atokan Red Oak sandstone is a sublithic arenite deposited by westward flowing turbidites in slope channels localized above normal faults formed during tectonic breakdown of the precursor shelf. During burial, diagenesis destroyed porosity in some slope channel facies and enhanced porosity in others. During methane generation in encasing shales, the Red Oak was an amalgamation of porous and nonporous slope channel sandstones. Compression associated with late stages of Ouachita orogenesis deformed the reservoir horizon into a thrusted anticline, separated from the underlying Spiro by decollements in intervening shales. In contrast to the Spiro, optimum Red Oak reservoir quality occurs along linear, east-west channel trends at locations that were structurally low at the time of deposition and diagenesis.

    1993-02-01

    The Wichita uplift in southwestern Oklahoma is one part of a record of Pennsylvania and early Permian deformation that affected the Southern Oklahoma aulacogen. As a result of a partial inversion, the Lower Paleozoic section of this aulacogen was sequentially stripped off an uplift between the Wichita uplift and the Anadarko basin, resulting in the exposure of ultrabasic rocks deep in the Cambrian igneous fill of the aulacogen. Following the late Paleozoic tectonism, the topography of the uplift was entombed beneath Permian sediments and remained essentially undisturbed until exhumation during the present erosional cycle. Modern erosion is gradually exposing this topography, permitting morphometric analysis of the Permian hill forms. Because of the variation of lithology in the uplift, it is possible to isolate the effects of weathering processes such as intense hydrolysis of the igneous rocks (producing, among other features, or topography) and limestone dissolution, in the form of a surface and subsurface karst imprint. The latter process resulted in a network of small caves that are essentially fissures eroded along tectonic fractures. These small caves can be found in all the exposed areas of limestone. They are particularly noteworthy for three reasons: in at least five examples they contain a complex fauna of Permian vertebrates (mostly fragmentary), speleothems in some examples contain hydrocarbon inclusions, derived from the underlying Anadarko basin, some of the caves yield evidence of post burial evolution in the form of clay infiltration from the surface and brine flushing from the underlying Anadarko basin.

    SciTech Connect

    Ferebee, C. )

    1991-03-01

    Development of the southern Oklahoma aulacogen was the result of Cambrian tectonism along Proterozoic zones of weakness that caused northwest-trending extensional normal faults related to a rifting event. These faults were reactivated during upper Paleozoic compressional stress with fault patterns indicative of sinistral transpressive and transtensional movement. Mapping in the region has allowed classification of the myriad of faults into six major systems, from the north to south: the Washita Valley, Madill-Aylesworth, Caddo, Criner, Horseshoe Bend, and Muenster systems. Development of the fault systems occurred somewhat independently as energy was transferred between them owing to changes in stress from the uneven collision of the Ouachita front. This model may account for the episodic movement recognized by past investigators. The determination of relative timing of development within these systems has shown that the Madill-Aylesworth and Criner systems were active during the Upper Mississippian. As deformation continued along the Criner system structural activity moved southward to include the Horseshoe Bend and Muenster systems during the Early Pennsylvanian. During the Middle Pennsylvanian, fault development along the southern margin of the aulacogen subsided, and deformation activity was initiated in the northern portions of the Ardmore basin. The amount of horizontal displacement along fault systems in the region is still unresolved. However, by regional mapping along the Criner systems, a minimum of 6 mi left-lateral movement can be documented as having occurred during the Upper Pennsylvanian using models of sediment deposition and transport in strike-slip basins.

    Integrated Basin Chemical Modeling (IBCM) was developed as a predictive tool for frontier exploration and to date has been used in numerous basins worldwide. Amoco has utilized data from the mature Arkoma basin of eastern Oklahoma to verify the accuracy of this proprietary technique. The Arkoma basin was chosen as a test case due its complex tectonic history and the amount of subsurface data available. Several dip and strike depth-converted seismic lines were used to model timing of critical events: Spiro deposition, thrusting,maximum paleotemperature, generation and expulsion of hydrocarbons, genesis of pressure compartments and evolution of pressure seals within the basin. Preliminary IBCM simulations of basin thermal history indicate that the time of maximum temperature occurred at 280 mya, post-dating thrusting of the Ouachitas. Therefore, it is not necessary to palinspatically restore the traps within the thrusted terrain prior to identifying migration pathways. At the time of thrusting, 301 mya, the modeled pressures in the Atokan shales reached 7500 psi (500 atm) above normal hydrostatic pressures, creating effective pressure seals for the Pennsylvanian Spiro and Wapnucka reservoirs. Complex hydrologic flow thus became concentrated within these reservoir sections. The model also indicates that critical flow directions reversed several times during basin evolution. Additional work is underway to confirm paleo-geothermal gradients estimated from apatite fission track analysis and to define potential subtle traps using the diagenetic module of IBCM.

    The west-northwest trending Amarillo-Wichita Uplift in the Texas Panhandle and southwestern Oklahoma was produced as a result of recurrent large-scale intraplate deformation during the Late Paleozoic Ancestral Rocky Mountain orogeny. The area was broadly folded in the Late Devonian to Early Mississippian. Cambrian through Devonian units were downwarped into the Anadarko Basin, truncated by erosion, and unconformably overlain by Upper Devonian to Mississippian strata. To the south, Mississippian units overlie Ordovician strata and Precambrian basement along the axis of the Texas Arch. Strike-slip faulting along the axis of the Southern Oklahoma Aulacogen formed the Amarillo-Wichita Uplift during the Pennsylvanian. In the Texas Panhandle, the uplift has been internally deformed into a series of pull-apart grabens which are filled with up to 1500 m of Pennsylvanian arkosic debris. The Whittenburg Trough, a large pull-apart basin along the southwest flank of the uplift, contains about 2300 m of syntectonic deposits. Erosional edges of older units beneath the Mississippian are presently offset 120 km in a left-lateral sense along the uplift. Pre-Mississippian units located in the Hardeman Basin of southwestern Oklahoma originally aligned with those in the western Anadarko Basin of the Texas Panhandle. Restoration to the pre-faulting configuration also realigns offset Proterozoic basement terranes. The orientation of strike-slip and reverse faults and related folds indicate northeast-southwest directed compression during the Pennsylvanian.

The Simpson in Oklahoma, the Everton/St. Peter in Arkansas, and the Crystal Mountain/Mazarn/Blakely of the Ouachitas were studied in outcrop, and from well cuttings and logs to derive an understanding of 1) their stratigraphic relationships, 2) the nature and distribution of Simpson reservoir sands, 3) depositional and source environments, and 4) geologic history. Regional cross sections, sand distribution maps, and paleogeographic maps are used to illustrate these ideas and to point out areas favorable for oil and gas exploration.

  4. Heat flow in Oklahoma

    Twenty new heat flow values are incorporated, along with 40 previously published data, into a heat flow map of Oklahoma. The new heat flow data were estimated using previous temperature measurements in boreholes made by American Petroleum Institute researchers and 1,498 thermal conductivity measurements on drill cuttings. The mean of 20 average thermal gradients is 30.50spC/km. In general, thermal gradients increase from SW (14.11spC/km) to NE (42.24spC/km). The range of 1,498 in situ thermal conductivity measurements (after corrections for anisotropy, in situ temperature, and porosity) is 0.90-6.1 W/m-K; the average is 1.68 W/m-K. Estimated near-surface heat flow (20%) at 20 new sites in Oklahoma varies between 22 4 mW/msp2 and 86 17 mW/msp2; the average is 50 mW/msp2. Twenty-seven new heat-generation estimates, along with 22 previously published data, are used to create a heat generation map of Oklahoma. The range of heat production estimates is 1.1-3.5 muW/msp3, with an average of 2.5 muW/msp3. The heat flow regime in Oklahoma is primarily conductive in nature, except for a zone in northeast. Transient effects due to sedimentary processes and metamorphic/igneous activity, as well as past climatic changes, do not significantly influence the thermal state of the Oklahoma crust. Heat flow near the margins of the Arkoma and Anadarko Basins may be depressed or elevated by 5-13 mW/msp2 by refraction of heat from sedimentary rocks of relatively low thermal conductivity (1-2 W/m-K) into crystalline basement rocks of relatively high thermal conductivity (3-4 W/m-K). The heat generation-heat flow relationship shows a modest correlation. The relatively high heat flow (70-80 mW/msp2) in part of northeastern Oklahoma suggests that the thermal regime there may be perturbed by regional groundwater flow originating in the fractured outcrops of the Arbuckle-Simpson aquifer in the Arbuckle Mountains.

    Geographic Information Systems have many uses, one of which includes the reproducible computation of environmental characteristics that can be used to categorize hydrologic features. The Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality are investigating Geographic Information Systems techniques to determine partial drainage-basin areas, stream-buffer areas, stream length, and land uses (drainage basin and stream characteristics) in northeastern Oklahoma. The U.S Geological Survey, in cooperation with Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality, documented the methods used to determine drainage-basin and stream characteristics for the Neosho and Spring Rivers above Grand Lake Of the Cherokees in northeastern Oklahoma and calculated the characteristics. The drainage basin and stream characteristics can be used by the Oklahoma Department of Wildlife Conservation and the Oklahoma Department of Environmental Quality to aid in natural-resource assessments.

  6. Integrated geophysical investigations of linkages between Precambrian basement and sedimentary structures in the Ucayali basin, Peru; Fort Worth basin, Texas; and Osage County, Oklahoma

    I conducted integrated geophysical studies within the Fort Worth basin, Texas; Osage County, Oklahoma, and the Ucayali basin, Peru. My studies are directed at understanding the relationships or links between Precambrian basement structures and sedimentary structures using these three areas as case studies. Links between basement structure, hydrocarbon reservoirs, and sedimentary sequences are not a new concept. Such relationships have been documented in the Paradox, Hardeman, Anadarko, Arkoma, Ardmore and Williston basins among others. Structures such as fault zones that can influence the formation of sedimentary basins and mineral deposits are often formed by intraplate tectonism. In order to compare the relationship between the Precambrian basement structures and sedimentary structures, I analyzed series of derivative and filtered maps of aeromagnetic and gravity data, which enhance basement structures, that were integrated with seismic data and seismic attribute data that enhance structures within the sedimentary sections. Other information such as well data and geologic information etc were also integrated. This integrated workflow facilitates the comparison of the links or relationships between the two structures. The results of the Fort Worth basin are presented in Chapter 3. The results of this integrated study show that the sedimentary structures within the study area are mainly related to basement structures because these structures are aligned parallel to anomalies identified on the high-resolution aeromagnetic (HRAM) data. The northeast-southwest and northwest-southeast orientations of sedimentary features are consistently parallel with Precambrian structural fabrics that are associated with structures such as the northeast trending Ouachita orogenic belt and the northwest trending Muenster Arch, which reactivated a late Cambrian/Late Precambrian faults. The knowledge gained in this study will impact oil and gas exploration and development within the study area because, the orientation of the natural and induced fractures can be predicted even if seismic data is limited or unavailable. In Chapter 4, the results of an integrated analysis that includes the use of 3D seismic data, seismic attributes, and derivative maps from potential field data to study the basement, Mississippi Chert and the Arbuckle Group of Osage County, Oklahoma are presented. The workflow employed in this study was effective in studying and identifying polygonal, highly coherent, and high amplitude lineaments that strike northwesterly and northeasterly within these reservoirs. Basement structure lineaments are found to be parallel in orientation with the trend of lineaments seen within the Mississippian Chert and the Arbuckle Group. The northwest-striking lineaments may be related to the late-Paleozoic tectonism that affected both the Precambrian and Paleozoic section of Osage County. Another part of this research investigated the large gravity and magnetic anomalies and their association with the Mid-Continent Rift System (MCRS). Results of this analysis revealed prominent northeast trending anomalies that suggest that the MCRS extends into northern Oklahoma. However, geochronological data for basement rocks suggest that this extension would have to be limited to intrusive bodies that have little or no subcrops. The integrated study conducted in the Ucayali basin of Peru revealed that the northwest-southeast trending lineaments interpreted as Precambrian basement structures are sub-parallel to the late Paleozoic fold and thrust belts that resulted from the shortening associated with the formation of the Andes. These fold and thrust belts are reactivated along the zones of weaknesses that already existed in the Precambrian basement. The east-northeast lineaments are located beneath the Fitzcarrald Arch locate above the buoyant Nazca ridge. I interpret these east-northeast lineaments as part of the Ene Pisco -- Abancay Fitzcarrald tectonic lineaments, which is one of the five tectonic domains in these region. Gravity modeling suggests that the crustal thickness and the subduction slab-dip beneath Peru increase from the north of the Ucayali basin towards the south. My 2-dimensional gravity model suggests that the crust thickness and Nazca plate dip increase southward within the Ucayali basin. These results also establish a correlation between known geologic features and the regional gravity anomalies.

    The author has identified the following significant results. ERTS-1 data give exploration geologists a new perspective for looking at the earth. The data are excellent for interpreting regional lithologic and structural relationships and quickly directing attention to areas of greatest exploration interest. Information derived from ERTS data useful for petroleum exploration include: linear features, general lithologic distribution, identification of various anomalous features, some details of structures controlling hydrocarbon accumulation, overall structural relationships, and the regional context of the exploration province. Many anomalies (particularly geomorphic anomalies) correlate with known features of petroleum exploration interest. Linears interpreted from the imagery that were checked in the field correlate with fractures. Bands 5 and 7 and color composite imagery acquired during the periods of maximum and minimum vegetation vigor are best for geologic interpretation. Preliminary analysis indicates that use of ERTS imagery can substantially reduce the cost of petroleum exploration in relatively unexplored areas.

    1989-03-01

    The Middle Pennsylvanian Red Fork sandstone formed as a result of progradation across eastern Kansas and most of Oklahoma. The Red Fork is one of several transgressive-regressive sequences (cyclothems) developed within the Desmoinesian Cherokee Group. Sea level changes, together with varying subsidence, were dominant factors controlling the general stratigraphic (correlative) characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the more active part of the basin during lower sea level stands and valley-fill deposition in the more stable areas during sea level rises. A map of Red Fork sand trends reveals an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northernmost part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope basinal-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock and log data. Logs need to be calibrated to cores in order to estimate depositional environments accurately and to make a reasonable assessment of diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, and a significant amount of oil is in channel sandstones with trends at high angles to the structural grain. In some areas, secondary clay, in particular chloritic clay, has resulted in microporosity, high water saturation, and correspondingly low resistivities in oil reserves.

    Desmoinesian sandstones from the northeast Oklahoma platform and from the Anadarko and McAlester basins record a complex interaction between mid-Pennsylvanian source-area tectonism and cyclic sedimentation patterns associated with transgressions and regressions. Framework grain summaries for 67 thin sections from sandstones of the Cherokee Group (Bartlesville, Red Fork, Skinner, and Prue) were subjected to multivariate statistical analysis to establish regional compositional trends for provenance analysis. R-mode cluster and correspondence analyses were used to determine the contributing effect (total variance) of key framework grains. Fragments of monocrystalline and polycrystalline quartz, chert, metamorphic rock, and limestone contribute most to the variation in the grain population. Q-mode cluster and correspondence analyses were used to identify three distinct petrofacies. Petrofacies I is rich in monocrystalline quartz (86 to 98%) and contains rare mica and rock fragments. Petrofacies II is also rich in monocrystalline quartz (66 to 86%) and contains as much as 15% metamorphic and sedimentary rock fragments. Petrofacies III is compositionally heterogeneous and contains fragments of polycrystalline and monocrystalline quartz, mica, chert, and metamorphic and sedimentary rocks. Quantitative analyses indicate that Desmoinesian sandstones were derived from complex sedimentary and metamorphic source areas. Petrofacies I sandstones are restricted to the southwestern part of the Anadarko basin and the northeast Oklahoma platform, whereas petrofacies II and III sandstones are distributed throughout the study area. The distribution of petrofacies within the region suggests a model of source-area interaction and cratonic sediment recycling.

    Vitrinite-reflectance techniques were used to determine if there is a relationship between present geothermal gradient and coal rank in the Arkoma Basin. Three coal seams from high geothermal-gradient areas were compared with the same coal seams, respectively, from low geothermal-gradient areas. Samples were obtained from three core holes that were drilled in the high geothermal-gradient areas in Pittsburg and Haskell Counties, and three core holes that were drilled in the low geothermal-gradient areas in Latimer and Muskogee Counties. Nine additional coal samples were collected from active coal mines and one from an outcrop to supplement the core samples. The vitrinite-reflectance data indicates the present geothermal gradient did not produce the coal rank in the Arkoma Basin of Oklahoma. The coal rank is believed to have developed during the late Paleozoic, possibly in connection with the Ouachita orogeny. The coal isocarb maps suggest that the present geothermal-gradient pattern reflects the paleogeothermal gradient that produced the coal rank. Perhaps the intense folding and faulting associated with the Ouachita orogeny combined to transmit heat from the basement along an east-west thermal-anomaly zone through Haskell and Pittsburg Counties, Oklahoma. 60 refs., 16 figs., 3 tabs.

    1991-11-17

    The Arbuckle Mountains, named for Brigadier General Matthew Arbuckle, are located in south-central Oklahoma. The formations that comprise the Arbuckle Mountains have been extensively studied for hydrocarbon source rock and reservoir rock characteristics that can be applied to the subsurface in the adjacent Anadarko and Ardmore basins. Numerous reports and guidebooks have been written concerning the Arbuckle Mountains. A few important general publications are provided in the list of selected references. The purpose of this handout is to provide general information on the geology of the Arbuckle Mountains and specific information on the four field trip stops, adapted from the literature. The four stops were at: (1) Sooner Rock and Sand Quarry; (2) Woodford Shale; (3) Hunton Anticline and Hunton Quarry; and (4) Tar Sands of Sulfur Area. As part of this report, two papers are included for more detail: Paleomagnetic dating of basinal fluid migration, base-metal mineralization, and hydrocarbon maturation in the Arbuckle Mountains, Oklahoma and Laminated black shale-bedded chert cyclicity in the Woodford Formation, southern Oklahoma.

    Recurrent uplift of the Ouachita fold belt in Oklahoma coincided with the disruption of the Arkoma basin following the deposition of the Boggy Formation (early Desmoinesian time). The Boggy, composed of sandstone-shale sequences that record southerly progradation of coal-bearing, fluvially dominated deltaic complexes into the Arkoma basin, was folded at the time of uplift of the Ouachita fold belt. The uplift ended the progressive subsidence of the Arkoma basin and shifted the depocenter to the northwest. Subsequently, the Thurman Formation (middle Desmoinesian), which had a source in the southeast, was deposited in the smaller resurgent foreland basin over the folded and eroded surface of the Boggy. Chert-pebble conglomerates in the Thurman were derived from the erosion of newly elevated Ordovician and Devonian cherts in the core of the Ouachita foldbelt. Sandstone-shale packages are found in both formations. The origin of the coal-bearing cycles in the Boggy are enigmatic, but they probably were controlled by a combination of factors such as glacio-eustatic changes in sea level and delta-lobe abandonment. In contrast, cycles in the Thurman probably were strongly influenced by episodic thrust faulting and uplift in the Ouachitas.

    Cottonwood Creek basin is a 377 square mile area in central Oklahoma. The rim of the basin has altitudes as high as 1,300 feet, and the mouth is at an altitude of 910. Deposits of Quaternary age consist of alluvium along the stream courses and high terrace deposits along the southern rim of the basin. The alluvium contains a high percentage of clay and silt, ranges in thickness from a few inches to 40 feet, and underlies about 36 square miles of the basin. Sandstone, siltstone, and shale of Permian age, which form the bedrock, consist of the Garber sandstone along the eastern edge, the Hennessey shale through the central part, and Flowerpot shale along the western edge. Replenishment of water in the alluvium is from precipitation, lateral seepage and runoff from adjoining areas, and infiltration from the stream channels during high flows. The major use of ground water in the alluvium is transpiration by cottonwood and willow trees. Virtually no water is withdrawn from the alluvium by wells. (available as photostat copy only)

    1989-10-01

    Synthesis of oil field studies, seismic reflection data, and surface geology has resulted in a reconstruction of the Pennsylvanian evolution of the structural style of fault systems bordering and within the Ardmore Basin in south central Oklahoma. Faults bounding the margins of the basin were part of a broader left-lateral shear belt that affected southern Oklahoma during the early Pennsylvanian. The mid-Pennsylvanian and later zone of deformation contracted in southern Oklahoma to concentrate on the Washita Valley-Eola Robberson fault systems along the northern edge of the basin, and on the Criner Uplift-Healdton-Stephens County fault systems along the southern and western side of the basin. Deformation on the floor of the basin was amplified, with left-lateral strike-slip faults slicing the basin into a system of rhombohedral blocks. Deformation continued at least into Virgil time (late Pennsylvanian). A two-dimensional displacement field derived for the middle to late Pennsylvanian deformation reveals that a strong component of transpression affected both the basin-bounding faults and, by reason of the geometry of their connections to the west, the Wichita Mountain front as well. Broadly spread left-lateral shear evolved into crustal scale transpression during the Pennsylvanian Period. That progressive contraction of deformation and the change in style correlate with mid-Pennsylvanian approach and passage of the Ouachita collision along the Ouachita embayment (Thomas, 1983) on the southern margin of the North American craton. Inasmuch as the Ardmore Basin was located at the sharp internal corner of the embay ment, the coincidence suggests that the style of evolution records (1) early far-field influence of the approaching Ouachita collision during early Pennsylvanian, (2) passage of the suture during mid-Pennsylvanian, and (3) concentration of foreland deformation at the corner of the embayment as the Arkoma and Fort Worth flexural basins evolved to the south and east during late Pennsylvanian.

    1995-09-01

    Red Oak field,located in the Arkoma basin of Eastern Oklahoma, produces 200 Mmcfd of gas under pressure depletion drive with 2.6 TCF of gas recoverable. Structurally, the field occupied a position along the northern flank of the southward collapsing shear-margin formed during the Ouachita Orogeny. The basin flank is characterized by rapid subsidence and deposition of over 20,000 feet (6000 m) of shallow to deep marine shale and stacked sandstone in Atokan time (mid-late Carboniferous). This sequence culminates with a shoaling upward cycle and is structurally deformed by earliest Desmoinesian thrusting (280-265 Mya). Interpretation from an 18 mi{sup {center_dot}2} (47km{sup 2}) 3-D seismic survey was integrated with available with available well control and litho-facies mapping defining detailed structural irregularities and providing new drillsites while reducing economic risk. Resolution of data from the 3D seismic survey varied greatly. The one failed aspect of the original 3D survey design was to precisely map Red Oak sandstone. However, the survey was robust enough to provide excellent shallow and deep data, leading to identification of additional reservoir targets and multiple drilling proposals.

    The Middle Pennsylvanian Red Fork sandstone formed as a result of southward progradation across most of Oklahoma. The Red Fork is one of several cyclothemic (transgressive-regressive) sequences developed within the Desmoinesian Cherokee Group. Sea level changes and stability of the depositional area were dominant factors in determining the general stratigraphic characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the distal, more subsident part of the basin during lower sea level stands, and valley-fill deposition in the more stable areas during sea level rises. Red Fork sandstone trends depict an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northern part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope/basin-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock data and log data, with logs calibrated to cores for estimating depositional environments and assessing diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, some of which represent channelized sandstones with trends at high angles to the structural grain. Secondary chlorite, in particular, is associated locally with development of productive reservoirs showing microporosity, high water saturation, and correspondingly low resistivities.

    A study was conducted to investigate the effect of operator variability and subjectivity in lineament mapping and to examine methods to minimize or eliminate these problems by use of several machine preprocessing methods. LANDSAT scenes from the Anadarko Basin of Oklahoma and the Colorado Plateau were analyzed as test cases. Four geologists mapped lineaments on an Anadarko Basin scene, using transparencies of MSS bands 4-7, and their results are compared statistically. The total number of fractures mapped by the operators and their average lengths varied considerably, although comparison of lineament directions revealed some consensus. A summary map (785 linears) produced by overlaying the maps generated by the four operators showed that only 0.4% were recognized by all four operators, 4.7% by three, 17.8% by two and 77% by one operator. Two methods of machine aided mapping were tested, both simulating directional filters. One consists of computer (digital) processing of CCTs using edge enhancement algorithms, the other employs a television (analog) scanning of an image transparency which superimposes the original image and one offset in the direction of the scan line.

    The U.S. Geological Survey, in cooperation with the city of Oklahoma City, collected water-quality samples from the North Canadian River at the streamflow-gaging station near Harrah, Oklahoma (Harrah station), since 1968, and at an upstream streamflow-gaging station at Britton Road at Oklahoma City, Oklahoma (Britton Road station), since 1988. Statistical summaries and frequencies of detection of water-quality constituent data from water samples, and summaries of water-quality constituent data from continuous water-quality monitors are described from the start of monitoring at those stations through 2009. Differences in concentrations between stations and time trends for selected constituents were evaluated to determine the effects of: (1) wastewater effluent discharges, (2) changes in land-cover, (3) changes in streamflow, (4) increases in urban development, and (5) other anthropogenic sources of contamination on water quality in the North Canadian River downstream from Oklahoma City. Land-cover changes between 1992 and 2001 in the basin between the Harrah station and Lake Overholser upstream included an increase in developed/barren land-cover and a decrease in pasture/hay land cover. There were no significant trends in median and greater streamflows at either streamflow-gaging station, but there were significant downward trends in lesser streamflows, especially after 1999, which may have been associated with decreases in precipitation between 1999 and 2009 or construction of low-water dams on the river upstream from Oklahoma City in 1999. Concentrations of dissolved chloride, lead, cadmium, and chlordane most frequently exceeded the Criterion Continuous Concentration (a water-quality standard for protection of aquatic life) in water-quality samples collected at both streamflow-gaging stations. Visual trends in annual frequencies of detection were investigated for selected pesticides with frequencies of detection greater than 10 percent in all water samples collected at both streamflow-gaging stations. Annual frequencies of detection of 2,4-dichlorophenoxyacetic acid and bromacil increased with time. Annual frequencies of detection of atrazine, chlorpyrifos, diazinon, dichlorprop, and lindane decreased with time. Dissolved nitrogen and phosphorus concentrations were significantly greater in water samples collected at the Harrah station than at the Britton Road station, whereas specific conductance was greater at the Britton Road station. Concentrations of dissolved oxygen, biochemical oxygen demand, and fecal coliform bacteria were not significantly different between stations. Daily minimum, mean, and maximum specific conductance collected from continuous water-quality monitors were significantly greater at the Britton Road station than in water samples collected at the Harrah station. Daily minimum, maximum, and diurnal fluctuations of water temperature collected from continuous water-quality monitors were significantly greater at the Harrah station than at the Britton Road station. The daily maximums and diurnal range of dissolved oxygen concentrations were significantly greater in water samples collected at the Britton Road station than at the Harrah station, but daily mean dissolved oxygen concentrations in water at those streamflow-gaging stations were not significantly different. Daily mean and diurnal water temperature ranges increased with time at the Britton Road and Harrah streamflow-gaging stations, whereas daily mean and diurnal specific conductance ranges decreased with time at both streamflow-gaging stations from 19882009. Daily minimum dissolved oxygen concentrations collected from continuous water-quality monitors more frequently indicated hypoxic conditions at the Harrah station than at the Britton Road station after 1999. Fecal coliform bacteria counts in water decreased slightly from 19882009 at the Britton Road station. The Seasonal Kendall's tau test indicated significant downward trends in

    Water levels have declined in the southern part of the High Plains aquifer of the central USA since the mid-1960s in response to extensive irrigation development. The North Canadian River originates in western Oklahoma, and most of the basin is underlain by the High Plains aquifer. Average river flow in the headwaters near Guymon, Oklahoma, has decreased from about 0.9 m3/s before 1970 to near zero at present. Canton Lake, on the North Canadian River near Seiling, about 250 km downstream from Guymon, is a source of water supply for Oklahoma City. Precipitation data and streamflow data for gages upstream from Canton Lake were divided into an "early" period ending in 1971 and a "recent" period that begins in 1978. The early period represents conditions before ground-water levels had declined appreciably in the High Plains aquifer, and the recent period reflects the current condition, including the effects of storage reservoirs. Tests for trend and comparisons of flows between the early and recent periods show that the total annual volume of flow and the magnitudes of instantaneous annual peak discharges measured at most locations in the North Canadian River basin have decreased. Precipitation records for the area, however, show no corresponding changes. The decreases in average annual flow, expressed as a percentage of the average flows for the early period, ranged from 91 percent near Guymon to 37 percent near Canton Lake. A major contributing factor in the decreased flows appears to be the large declines in water levels in the High Plains aquifer.

  6. Relation of lower morrow sandstone and porosity trends to chester paleogeomorphology, Persimmon Creek field area, Northwestern Oklahoma

    Webster, R.E.

    1983-11-01

    Thickness and porosity trends of several lower Morrow sandstone units were strongly influenced by the paleogeomorphology of the subjacent Mississippian Chester limestone in a study area near Persimmon Creek field in T20N, R22W, southwestern Woodward County, Oklahoma. PrePennsylvanian streams flowing south-southwest across the Anadarko basin shelf had created a dendritic drainage pattern with paleogradients of about 40 ft/mi(7.5 m/km), and intervening stream divides were 50 to 100 ft (15 to 30 m) above the valley floors. As the sea transgressed the area in the Early Pennsylvanian, cyclic transgressions and regressions led to deposition of four prominent lower Morrow sandstone members separated by shale units which are approximately parallel lithologic time markers.

  7. Source rock potential of Upper Devonian-Lower Mississippian formations in Oklahoma and western Arkansas

    In central and southern Oklahoma, Upper Devonian-Lower Mississippian strata are rich oil source beds (mean = 7% TOC) at an early stage of generation. The major accumulations of oil in this region have been documented as coming from the Woodford formation. Equivalent-age source rocks in the deep part of the Anadarko basin have matured to or beyond the gas generation stage and significant generation is still occurring within parts of the basin. Around the Ozark uplift, age-equivalent rocks contain less organic matter (mean = 3.5% TOC) and more terrigenous clastic sediment than in central and southern Oklahoma. Both oil- and gas-generating types of kerogen are present and the organic matter has reached the early to main stages of oil generation. Upper Devonian-Lower Mississippian source rocks in the Ouachita core area are metamorphosed and no longer have significant hydrocarbon-generating capability. Age-equivalent rocks in the frontal zone are rich oil source beds at an early stage of generation. Significant hydrocarbon accumulations are possible at depth within the frontal zone and from frontal zone rocks that have been overthrust by metamorphosed Ouachita core-area rocks, particularly in the northwestern part of the Ouachita province.

    Westfall, A.O.; Cummings, T. Ray

    1963-01-01

    This report summarizes basic hydrologic data of the surface water resources of Muddy Boggy River basin, and by analysis and interpretation, presents certain streamflow characteristics at specified points in the basin. Muddy Boggy River has a drainage area of 2,429 square miles. The climate is moist subhumid and the annual precipitation averages about 39 inches. Gross annual lake evaporation averages 54 inches. The average annual discharge at the gaging stations for the period 1938-62 was 24,000 acre-feet for Chickasaw Creek near Stringtown; 72,000 acre-feet for McGee Creek near Stringtown; 671,800 acre-feet for Muddy Boggy Creek near Farris; and 358,200 acre-feet for Clear Boggy Creek near Caney. Flow-duration curves of daily discharge have been developed to show the percentage of time various rates of discharge have been equaled or exceeded. Procedures for determining the frequency of annual floods at any point in the basin are given. Low-flow frequency curves that define the recurrence intervals of 7, 14, 30, 60, and 120 day mean flows have been prepared for two gaging stations. Curves showing the relation of measured discharge at the low-flow partial-record stations to the daily mean discharge at a base gaging station are presented. Discharge measurements made in February 1963 at selected sites show the areal distribution of low flow. The storage requirements to supplement natural flows have been prepared for two gaging-stations sites. The chemical quality of surface water of Muddy Boggy River basin varies from place-to-place during base flow periods. Limestone and dolomite outcrops and oilfield brines affect water quality in some areas. Water of North Boggy Creek, McGee Creek, and their tributaries contains less than 100 ppm (parts per million) dissolved solids. Water of other streams in Muddy Boggy River basin has a higher dissolved-solids content, but the content does not exceed 500 ppm. Water of Muddy Boggy River basin is usable for domestic, irrigation, and most industrial purposes. Softening of water from some streams may be desirable, however.

  12. Petroleum system analysis of the Hunton Group in West Edmond field, Oklahoma

    2013-01-01

    West Edmond field, located in central Oklahoma, is one of the largest oil accumulations in the SilurianDevonian Hunton Group in this part of the Anadarko Basin. Production from all stratigraphic units in the field exceeds 170 million barrels of oil (MMBO) and 400 billion cubic feet of gas (BCFG), of which approximately 60 MMBO and 100 BCFG have been produced from the Hunton Group. Oil and gas are stratigraphically trapped to the east against the Nemaha uplift, to the north by a regional wedge-out of Hunton strata, and by intraformational diagenetic traps. Hunton Group reservoirs are the Bois d'Arc and Frisco Limestones, with lesser production from the Chimneyhill subgroup, Haragan Shale, and Henryhouse Formation. Hunton Group cores from three wells that were examined petrographically indicate that complex diagenetic relations influence permeability and reservoir quality. Greatest porosity and permeability are associated with secondary dissolution in packstones and grainstones, forming hydrocarbon reservoirs. The overlying DevonianMississippian Woodford Shale is the major petroleum source rock for the Hunton Group in the field, based on one-dimensional and four-dimensional petroleum system models that were calibrated to well temperature and Woodford Shale vitrinite reflectance data. The source rock is marginally mature to mature for oil generation in the area of the West Edmond field, and migration of Woodford oil and gas from deeper parts of the basin also contributed to hydrocarbon accumulation.

  14. Changes in flow in the Beaver-North Canadian River basin upstream from Canton Lake, western Oklahoma

    Wahl, Kenneth L.; Tortorelli, Robert L.

    1997-01-01

    This report presents the results of an evaluation of hydrologic data for the Beaver-North Canadian River basin upstream from Canton Lake in western Oklahoma. It examines the climatic and hydrologic data for evidence of trends. The hydrologic data examined includes total annual flow, base flow, and annual peak discharges. This study was conducted to determine if there is evidence of trends present in hydrologic and climatic data. All available streamflow-gaging station data, with at least 10 or more years of record, were examined for trends. In addition, the data were divided into an 'early' period (ending in 1971), representing conditions before ground-water levels had declined appreciably, and a 'recent' period (1978-1994), reflecting the condition of declining ground-water levels, including the effects of storage reservoirs. Tests for trend, moving averages, and comparisons of median and average flows for an early period (ending in 1971) with those for the recent period (1978-1994) show that the total annual volume of flow and the magnitudes of instantaneous annual peak discharges measured at most gaging stations in the Beaver- North Canadian River basin have decreased in recent years. Precipitation records for the panhandle, however, show no corresponding changes. The changes in flow are most pronounced in the headwaters upstream from Woodward, but also are evident at Woodward and near Seiling, which represents the inflow to Canton Lake. The average annual discharge decreased between the early period and the recent period by the following amounts: near Guymon, 18,000 acre-feet; at Beaver, 68,000 acre-feet; at Woodward, 72,000 acre-feet; and near Seiling, 63,000 acre-feet. These decreases, expressed as a percentage of the average flows for the early period, were 91 percent near Guymon, 82 percent at Beaver, 49 percent at Woodward, and 37 percent near Seiling. The medians of the annual peak discharges decreased from the early period to the recent period by the following amounts: near Guymon, 98 percent; at Beaver, 86 percent; at Woodward, 80 percent; and near Seiling, 53 percent. The Guymon gage is not affected by reservoirs; the other three mainstem gaging stations are influenced by reservoirs, but the decreases in annual peak discharges are greater than can be explained by storage in those reservoirs. Base flows have undergone substantial change, but unlike the annual volumes the base flows show some increases and some decreases. Flow duration analyses show a shift in the distribution of annual flows. Less contribution is coming from large floods that formerly added substantially to the yearly average flows. Near Seiling, for example, the magnitudes of the large flows that occur less than about 20 percent of the time were greatly reduced in the recent period. A primary mechanism producing these decreased streamflows appears to be the depletion of ground water in the High Plains aquifer that underlies more than 90 percent of the basin. Changes in farming and conservation practices and in water use also may be having an effect.

  15. Stability of salt in the Permian salt basin of Kansas, Oklahoma, Texas and New Mexico, with a section on dissolved salts in surface water

    1973-01-01

    The Permian salt basin in the Western Interior of the United States is defined as that region comprising a series of sedimentary basins in which halite and associated salts accumulated during Permian time. The region includes the western parts of Kansas, Oklahoma, and Texas, and eastern parts of Colorado and New Mexico. Following a long period of general tectonic stability throughout the region during most of early Paleozoic time, there was much tectonic activity in the area of the Permian salt basin during Late Pennsylvanian and Early Permian time just before bedded salt was deposited. The Early Permian tectonism was followed by stabilization of the basins in which the salt was deposited. These salt basins were neither contemporaneous nor continuous throughout the region, so that many salt beds are also discontinuous. In general, beds in the northern part of the basin (Kansas and northern Oklahoma) are older and the salt is progressively younger towards the south. Since Permian time the Permian salt basin has been relatively stable tectonically. Regionally, the area of the salt basin has been tilted and warped, has undergone periods of erosion, and has been subject to a major incursion of the sea; but deep-seated faults or igneous intrusions that postdate Permian salt are rare. In areas of the salt basin where salt is near the surface, such as southeastern New Mexico and central Kansas, there are no indications of younger deep-seated faulting and only a few isolated igneous intrusives of post-Permian age. On the other hand, subsidence or collapse of the land surface resulting from dissolution has been commonplace in the Permian salt basin. Some dissolution of salt deposits has probably been taking place ever since deposition of the salt more than 230 million years ago. Nevertheless, the subsurface dissolution fronts of the thick bedded-salt deposits of the Permian basin have retreated at a very slow average rate during that 230 million years. The preservation of bedded salt from subsurface dissolution depends chiefly on the isolation of the salt from moving ground water that is not completely saturated with salt. Karst topography is a major criterion for recognizing areas where subsurface dissolution has been active in the past; therefore, the age of the karst development is needed to provide the most accurate estimate of the dissolution rate. The Ogallala Formation-of Pliocene age is probably the most widespread deposit in the Permian salt basin that can be used as a point of reference for dating the development of recent topography. It is estimated that salt has been dissolved laterally in the vicinity of Carlsbad, New Mexico, at an average rate of about 6-8 miles per million years. Estimates of future rates of salt dissolution and the resulting lateral retreat of the underground dissolution front can be projected with reasonable confidence for southeastern New Mexico on the assumption that the climatic changes there in the past 4 million years are representative of climatic changes that may be expected in the near future of geologic time. Large amounts of salt are carried by present-day rivers in the Permian salt basin; some of the salt is derived from subsurface salt beds, but dissolution is relatively slow. Ground-water movement through the Permian salt basin is also relatively slow.

  17. Cenozoic denudation of the Wichita Mountains, Oklahoma, and southern mid-continent: apatite fission-track thermochronology constraints

    Winkler, Jennifer E.; Kelley, Shari A.; Bergman, Steven C.

    1999-05-01

    Eight new apatite fission-track (AFT) analyses of igneous rocks constrain the low-temperature thermal history of the Wichita Mountains in southwestern Oklahoma. The apparent AFT ages for Mount Scott, which range from 10114 to 14645 Ma, display no systematic variation as a function of elevation. AFT age ranges for the rhyolite at Bally Mountain and Mount Sheridan Gabbro are 13636 to 16025 Ma and 20926 to 22236 Ma, respectively. The mean track lengths for the Wichita Mountain samples range from 11.8 to 13.4 ?m with standard deviations of 1.8-3.4 ?m, and the track-length distributions are broad with relatively few tracks longer than 14 ?m. The AFT age and length data are best fit by a thermal history involving heating of the basement rocks to temperatures of at least 115C prior to Late Jurassic time, denudation and associated cooling between Late Jurassic and Albian in response to the opening of the Gulf of Mexico, burial by 0.5-1.5 km of Cretaceous sedimentary rocks, and finally cooling due to denudation starting 55-25 Ma and continuing to the present. The thermal history recorded in the AFT data from the Wichita Mountains is similar to thermal histories derived from AFT thermochronology studies along the Ouachita Trend and in the Anadarko Basin. The new data, when combined with AFT data from the Ouachita Deformation Belt, the Anadarko Basin, the eastern Sangre de Cristo Mountains in New Mexico, and the eastern margins of the Wet Mountain and Front Range in Colorado, reveal an interesting pattern of post-Cretaceous denudation in the mid-continent. The amount of Neogene denudation increases westward from about 1 km to 3 km between southwestern Oklahoma and the eastern Sangre de Cristo Mountains in east-central New Mexico, and the timing of onset of denudation decreases from 55-25 Ma in the east to 35-12 Ma toward the west. Along the Southern Rocky Mountains-High Plains boundary, the amount of denudation decreases northward from about 3 km in the eastern Sangre de Cristo Mountains to 1 km along the east side of the Front Range. Post-Laramide isostatic adjustment of the High Plains, the development of the Rio Grande rift, and a shift towards a drier climate with seasonal, intense thunderstorms on the High Plains may all have contributed to the observed pattern of Cenozoic denudation in the southern mid-continent.

  18. Shallow subsurface geological investigation near the Meers fault, Oklahoma

    1993-02-01

    The Meers fault is part of a complex system of northwest-trending faults forming the boundary between the Wichita Mountains (south) and the Anadarko basin (north). The frontal fault system is dominated by moderately dipping to steeply dipping reverse faults which have a combined net vertical displacement of over 9 km. Of these faults, the Meers fault has a Pennsylvanian-Permian throw of about 2 km. The Meers fault trends N. 60[degree]W. and displaces Permian conglomerate and shale for a distance of at least 26 km, from near the Comanche-Kiowa County boundary to East Cache Creek. At the northwest end of the fault trace, the fault displaces limestone-pebble conglomerates (Post Oak), whereas at the southeast end siltstones and calcrete-bearing shales of the Hennessey are displaced. Multiple radiocarbon ages of soil-humus samples from 2 Canyon Creek trenches (S24, T4N, R13W) show the last surface faulting occurred 1,200--1,300 yr ago. In 1988--89, the Oklahoma Geological Survey drilled 4 core holes to basement in the vicinity of the trench sites. The holes were drilled along a 200-m-long transect normal to the strike of the Meers fault. Two holes were drilled on the north side of the fault and penetrated highly fractured and altered rhyolite at about 58 m. A third hole drilled 25 m south of the fault, intersected weathered and sheared gabbro at 58 m. The basement material in the fourth hole consisted of dark greenish brown, highly fractured and sheared rock. The drill holes encountered Permian, poorly sorted, matrix-supported, 0.5--3 m thick, conglomerate interbedded with shale and siltstone. Drill holes 1--3 contained 3--5 m thick, granite cobble-boulder, clast supported conglomerate resting on rhyolite and/or gabbro. The core-hole information suggests the Meers-fault zone is at least 200 meters wide.

    USGS Publications Warehouse

    Hart, D.L., Jr.

    1965-01-01

    The Washita River alluvial deposits between Clinton and Aandarko primarily are fine-grained sand and clay, and lesser amounts of coarser-grained material. These deposits range in thickness from 0 to 120 feet and average about 64 feet. Well yields range from only a few gallons per minute in some of the sandy clay beds to more than 240 gallons per minute (gpm) in sections where a higher percentage of coarse material has been deposited. Test pumping indicates that wells yielding 60 to 150 gpm could be developed in about 50 percent of the valley and wells yielding more than 150 gpm in about 10 percent. The higher yields generally occur along a relatively narrow buried channel where the alluvial deposits are thicker and coarser than the surrounding alluvium. This area is not discernible at the surface and must be located by test drilling.

  7. Using 3-D seismic inversion data as a tool for predicting porosity in the Wilburton gas field, Arkoma Basin, southeastern Oklahoma

    NASA Astrophysics Data System (ADS)

    Fuchs, Jeffrey Charles

    Understanding and identifying changes in rock properties over an area is critical in characterizing a reservoir. In order to identify porosity changes, a 3-D seismic inversion volume was inverted for acoustic impedance in the Red Oak and Brazil Sandstones in the Wilburton gas field located in the Arkoma Basin, southeastern Oklahoma. The tops and bases of these two sandstones were identified to be analyzed based on acoustic impedance and porosity. Establishing a relationship between acoustic impedance and porosity allows porosity to be predicted away from the wellbore using the seismic acoustic impedance data. Interpretation of the seismic inversion data suggests that a) there is a linear correlation between acoustic impedance and porosity in the sandstone portions of the Red Oak and Brazil Sandstones; b) seismic thickness cannot be used to predict actual thickness of these sandstone units due to variations in velocity; and c) prediction of porosity using seismic inversion data inverted for acoustic impedance in sandstone containing interbeds of shale is not reliable, and the method should be limited to homogeneous sandstone.

  8. Formulation of a correlated variables methodology for assessment of continuous gas resources with an application to the Woodford play, Arkoma Basin, eastern Oklahoma

    Shale gas is a form of continuous unconventional hydrocarbon accumulation whose resource estimation is unfeasible through the inference of pore volume. Under these circumstances, the usual approach is to base the assessment on well productivity through estimated ultimate recovery (EUR). Unconventional resource assessments that consider uncertainty are typically done by applying analytical procedures based on classical statistics theory that ignores geographical location, does not take into account spatial correlation, and assumes independence of EUR from other variables that may enter into the modeling. We formulate a new, more comprehensive approach based on sequential simulation to test methodologies known to be capable of more fully utilizing the data and overcoming unrealistic simplifications. Theoretical requirements demand modeling of EUR as areal density instead of well EUR. The new experimental methodology is illustrated by evaluating a gas play in the Woodford Shale in the Arkoma Basin of Oklahoma. Differently from previous assessments, we used net thickness and vitrinite reflectance as secondary variables correlated to cell EUR. In addition to the traditional probability distribution for undiscovered resources, the new methodology provides maps of EUR density and maps with probabilities to reach any given cell EUR, which are useful to visualize geographical variations in prospectivity.

  10. Three-dimensional seismic interpretation from the triangle zone of the frontal Ouachita mountains and Arkoma basin, Pittsburg County, Oklahoma

    1996-08-01

    Analysis of 28.5 km{sup 2} of three-dimensional (3-D) seismic reflection data from the triangle zone of the Ouachita fold-and-thrust belt and the foreland Arkoma basin reveals structural details not recognized previously in conventional two-dimensional (2-D) seismic data. The data indicate that the frontal Kiowa syncline in the Arkoma basin has been passively uplifted by blind thrusting at the Morrowan Wapanucka Limestone level, and that smaller wavelength folds are produced by thrusting at shallower levels in the Atoka Formation. Faulting at deeper levels in the Hunton and Arbuckle groups has been traditionally interpreted as normal, but our analysis of this data set indicates that, in this area, normal faults were reactivated during the Ouachita orogeny as reverse faults, and the changes in fault separation can be followed along strike. These faults show the same trend as the overlying thrusts and are normal or have minor inversion where the overlying thrusts have small displacement. These faults have been completely inverted where the overlying thrusts have more displacement, suggesting a genetic relation between the Wapanucka thrusts and the inversion of the Hunton and Arbuckle faults. Four reflections were chosen for analysis: one reflection in the lower Atoka Formation, two reflections repeated in the Wapanucka Limestone, and a fourth reflection in the Hunton Group. All of these surfaces exhibit the same geometry with the fold axes plunging to the southwest. Variations in bearing and plunge of fold axes in the Wapanucka Limestone can be directly correlated to changes in displacement and ramp height along strike. The similarity between surface geometries suggests that the last deformation took place at deeper levels in the Hunton and Arbuckle groups and folded the overlying thrusts. Reactivation of Atokan normal faults at deeper levels in the Arkoma basin and Ouachita subthrust play may be more widespread than previously recognized.

  11. Comparison of Irrigation Water Use Estimates Calculated from Remotely Sensed Irrigated Acres and State Reported Irrigated Acres in the Lake Altus Drainage Basin, Oklahoma and Texas, 2000 Growing Season

    Increased demand for water in the Lake Altus drainage basin requires more accurate estimates of water use for irrigation. The U.S. Geological Survey, in cooperation with the U.S. Bureau of Reclamation, is investigating new techniques to improve water-use estimates for irrigation purposes in the Lake Altus drainage basin. Empirical estimates of reference evapotranspiration, crop evapotranspiration, and crop irrigation water requirements for nine major crops were calculated from September 1999 to October 2000 using a solar radiation-based evapotranspiration model. Estimates of irrigation water use were calculated using remotely sensed irrigated crop acres derived from Landsat 7 Enhanced Thematic Mapper Plus imagery and were compared with irrigation water-use estimates calculated from irrigated crop acres reported by the Oklahoma Water Resources Board and the Texas Water Development Board for the 2000 growing season. The techniques presented will help manage water resources in the Lake Altus drainage basin and may be transferable to other areas with similar water management needs. Irrigation water use calculated from the remotely sensed irrigated acres was estimated at 154,920 acre-feet; whereas, irrigation water use calculated from state reported irrigated crop acres was 196,026 acre-feet, a 23 percent difference. The greatest difference in irrigation water use was in Carson County, Texas. Irrigation water use for Carson County, Texas, calculated from the remotely sensed irrigated acres was 58,555 acrefeet; whereas, irrigation water use calculated from state reported irrigated acres was 138,180 acre-feet, an 81 percent difference. The second greatest difference in irrigation water use occurred in Beckham County, Oklahoma. Differences between the two irrigation water use estimates are due to the differences of irrigated crop acres derived from the mapping process and those reported by the Oklahoma Water Resources Board and Texas Water Development Board.

    The Poteau Valley Improvement Authority uses Wister Lake in southeastern Oklahoma as a public water supply. Total phosphorus, total nitrogen, and suspended sediments from agricultural runoff and discharges from wastewater treatment plants and other sources have degraded water quality in the lake. As lake-water quality has degraded, water-treatment cost, chemical usage, and sludge production have increased for the Poteau Valley Improvement Authority. The U.S. Geological Survey (USGS), in cooperation with the Poteau Valley Improvement Authority, investigated and summarized concentrations of total phosphorus, total nitrogen, suspended sediment, and bacteria (Escherichia coli and Enterococcus sp.) in surface water flowing to Wister Lake. Estimates of total phosphorus, total nitrogen, and suspended sediment loads, yields, and flow-weighted mean concentrations of total phosphorus and total nitrogen concentrations were made for the Wister Lake Basin for a 3-year period from October 2010 through September 2013. Data from water samples collected at fixed time increments during base-flow conditions and during runoff conditions at the Poteau River at Loving, Okla. (USGS station 07247015), the Poteau River near Heavener, Okla. (USGS station 07247350), and the Fourche Maline near Leflore, Okla. (USGS station 07247650), water-quality stations were used to evaluate water quality over the range of streamflows in the basin. These data also were collected to estimate annual constituent loads and yields by using regression models. At the Poteau River stations, total phosphorus, total nitrogen, and suspended sediment concentrations in surface-water samples were significantly larger in samples collected during runoff conditions than in samples collected during base-flow conditions. At the Fourche Maline station, in contrast, concentrations of these constituents in water samples collected during runoff conditions were not significantly larger than concentrations during base-flow conditions. Flow-weighted mean total phosphorus concentrations at all three stations from 2011 to 2013 were several times larger than the Oklahoma State Standard for Scenic Rivers (0.037 milligrams per liter [mg/L]), with the largest flow-weighted phosphorus concentrations typically being measured at the Poteau River at Loving, Okla., station. Flow-weighted mean total nitrogen concentrations did not vary substantially between the Poteau River stations and the Fourche Maline near Leflore, Okla., station. At all of the sampled water-quality stations, bacteria (Escherichia coli and Enterococcus sp.) concentrations were substantially larger in water samples collected during runoff conditions than in water samples collected during base-flow conditions from 2011 to 2013. Estimated annual loads of total phosphorus, total nitrogen, and suspended sediment in the Poteau River stations during runoff conditions ranged from 82 to 98 percent of the total annual loads of those constituents. Estimated annual loads of total phosphorus, total nitrogen, and suspended sediment in the Fourche Maline during runoff conditions ranged from 86 to nearly 100 percent of the total annual loads. Estimated seasonal total phosphorus loads generally were smallest during base-flow and runoff conditions in autumn. Estimated seasonal total phosphorus loads during base-flow conditions tended to be largest in winter and during runoff conditions tended to be largest in the spring. Estimated seasonal total nitrogen loads tended to be smallest in autumn during base-flow and runoff conditions and largest in winter during runoff conditions. Estimated seasonal suspended sediment loads tended to be smallest during base-flow conditions in the summer and smallest during runoff conditions in the autumn. The largest estimated seasonal suspended sediment loads during runoff conditions typically were in the spring. The estimated mean annual total phosphorus yield was largest at the Poteau River at Loving, Okla., water-quality station. The estimated mean annual total phosphorus yield was largest during base flow at the Poteau River at Loving, Okla., water-quality station and at both of the Poteau River water-quality stations during runoff conditions. The estimated mean annual total nitrogen yields were largest at the Poteau River water-quality stations. Estimated mean annual total nitrogen yields were largest during base-flow and runoff conditions at the Poteau River at Loving, Okla., water-quality station. The estimated mean annual suspended sediment yield was largest at the Poteau River near Heavener, Okla., water-quality station during base-flow and runoff conditions. Flow-weighted mean concentrations indicated that total phosphorus inputs from the Poteau River Basin in the Wister Lake Basin were larger than from the Fourche Maline Basin. Flow-weighted mean concentrations of total nitrogen did not vary spatially in a consistent manner. The Poteau River and the Fourche Maline contributed estimated annual total phosphorus loads of 137 to 278 tons per year (tons/yr) to Wister Lake. Between 89 and 95 percent of the annual total phosphorus loads were transported to Wister Lake during runoff conditions. The Poteau River and the Fourche Maline contributed estimated annual total nitrogen loads of 657 to 1,294 tons/yr, with 86 to 94 percent of the annual total nitrogen loads being transported to Wister Lake during runoff conditions. The Poteau River and the Fourche Maline contributed estimated annual total suspended sediment loads of 110,919 to 234,637 tons/yr, with 94 to 99 percent of the annual suspended sediment loads being transported to Wister Lake during runoff conditions. Most of the total phosphorus and suspended sediment were delivered to Wister Lake during runoff conditions in the spring. The majority of the total nitrogen was delivered to Wister Lake during runoff conditions in winter.

    Hartshorne coals have long been known to be extremely gassy because early underground mines in the Arkoma basin were plagued by methane. Mine data, combined with recent advances in coal-bed methane technology, allow us to better quantify this gas resource. The gas content of Hartshorne coals is controlled by a number of factors, including thickness, thermal maturity, as content, and reservoir pressure. Hartshorne coal can be generally characterized as being thin (<6 ft), of relatively high thermal maturity (R[sub O] 0.7 to 1.7), and of relatively low ash content (<10%). Very little pressure data are available for the Hartshorne, but it appears that Hartshorne coals are underpressured to normally pressured with no indication of overpressuring. Estimates of gas in place for Hartshorne coal range from 2 to 6 bcf of gas per 640 ac. Primary controls on the producibility of methane from the Hartshorne include the hydrology of the coal, and its permeability. Conflicting data exist as to the nature of the hydrologic regime of the coal. The existence of dry coal in a variety of structural setting is well established. Free-water production from the coal, where present, tends to be low volume (<10 bbl/day) and of a brackish chloride composition. Permeability is controlled by a number of factors, including cleat intensity and tectonic fracturing. Locally diagenetic cements may significantly reduce permeability.

  14. Comparative evolution of Pennsylvanian platform margins in Oklahoma and north-central Texas

    Pennsylvanian evolution of the Midland basin's eastern shelf and the northern shelves of the Anadarko and Arkoma basins demonstrates a strongly contrasting pattern with regard to the facies composition and stability of the shelf margin. For the Midland basin a carbonate ramp system developed adjacent to the Eastern shelf during the early Desmoinesian but received no coarse-grained clastic sediment until after the central Fort Worth basin was completely filled by Ouachita orogenic debris in the late Desmoinesian. At that time, a distinct north-south hingeline formed between the shelf and incipient Midland basin that allowed for subsequent vertical accretion of a Missourian-age double bank system. Due to the absence of active deltaic depocenters across the southern two-thirds of the shelf, the Missourian shelf margin did not prograde basinward nor did a submarine fan system develop adjacent to this reciprocal bank complex. Later, during the Virgilian, a single shelf-edge bank and submarine fan complex prograded the shelf edge westward. The shelf edges for the Anadarko and Arkoma basins demonstrate a significantly different pattern. Only during the late Desmoinesian (Marmaton Group) did a shelf-edge bank develop in association with shelf-slope reciprocal sedimentation. For the Anadarko basin, widespread submarine fans, fed from a northeasterly cratonic source, are first seen with Red Fork deposition. Post-Tonkawa cyclic sedimentation prograded the shelf edge southward and gave rise to a more carbonate-dominated shelf sequence. In virtually all instances the regressive submarine fan units indicate eustatic lowstands of sea level.

    Possible causes for downward trends in phosphorus concentrations include decreases in phosphorus discharges from a wastewater-treatment plant upstream from the Spavinaw Creek near Cherokee City, Okla., streamflow-gaging station, and implementation of best management practices in the basin. Downward trends in sediment concentrations may be related to effects of best management practices in the basin.

    Dispersed kerogen of the Woodford-Chattanooga and Atoka Formations from the subsurface of the Arkoma Basin show a wide range of thermal maturities (0.38 to 6.1% R(o)) indicating thermal conditions ranging from diagenesis to incipient rock metamorphism. Raman spectral analysis reveals systematic changes of both the first- and second-order spectrum with increasing thermal maturity. These changes include a pronounced increase in the D/O peak height ratio accompanied by a narrowing of the D peak, a gradual decrease in the D/O peak width ratio, and a shift of both peaks toward higher wave numbers. Second-order Raman peaks, though less intensive, also show systematic peak shifting as a function of R(o). These empirical results underscore the high potential of Raman spectrometry as a fast and reliable geothermometer of mature to supermature hydrocarbon source rocks, and as an indicator of thermal maturity levels within the anchizone.Dispersed kerogen of the Woodford-Chattanooga and Atoka Formations from the subsurface of the Arkoma Basin show a wide range of thermal maturities (0.38 to 6.1% Ro) indicating thermal conditions ranging from diagenesis to incipient rock metamorphism.

    The mission of Oklahoma EPSCoR is to make Oklahoma researchers more successful in competing for research funding. Specific goals, objectives, and strategies were developed for each federal EPSCoR program, based on federal and state needs. A theme of stimulating collaboration among campuses and building on common research strengths is a strong component of the Oklahoma EPSCoR strategic plan. It extends also to our relationships with the federal agencies, and wherever possible, Oklahoma EPSCoR projects are developed collaboratively with federal research laboratories and program offices. Overall, Oklahoma EPSCoR seeks to capitalize on unique research capabilities and opportunities. The NASA EPSCoR Program in Oklahoma was developed through this grant as a joint effort between Oklahoma EPSCoR and the NASA Oklahoma Space Grant Consortium (OSGC). The major goal of the Oklahoma NASA EPSCoR Plan established in 1996 is to develop an academic research enterprise directed towards a long-term, self-sustaining, nationally competitive capability in areas of mutual self-interest to NASA and Oklahoma. Our final technical summary pie chart demonstrates the strong successes we have achieved during this period as a result of the award.

    Compelling scientific evidence suggests that a strong association exists between housing-related hazards and the health and safety of their residents. Health, safety, and environmental hazards (such as asthma and allergy triggers), unintentional injury hazards, lead-based paint hazards, and poor indoor air quality are interrelated with substandard housing conditions. This article describes a Healthy Homes initiative to address these hazards in a coordinated fashion in the home, rather than taking a categorical approach, even in the presence of multiple hazards. It also provides an overview of Oklahoma's Healthy Homes initiative and its pilot project, the Tulsa Safe and Healthy Housing Project, which is currently administered in Tulsa in collaboration with Children First, Oklahoma's Nurse-Family Partnership program. This pilot project seeks to open new areas of research that can lead to a greater understanding of environmental health issues related to substandard housing in the United States, which will eventually make homes safer and healthier.

    Global Land Data Assimilation System (GLDAS) models, especially the Community Land Model (CLM), show a continue reduction of soil moisture over Oklahoma region from 1980 to 2008. When the top 3.5 meter of surface is considered, the total water amounts estimated from models are within the ranges of 145-150, 140-145, 135-140, and 130-135 kg/m2 for the years of 1980-1986, 1987-1993, 1994-2000, and 2001-2008, respectively. A statistically significant decreasing trend of annual mean soil moisture is also found, indicating the region may experience a continuous drying period. Although the moisture change could be related to many factors, precipitation and evaporation potentially are the two dominant meteorological variables in determining the soil moisture variation. The rainfall amounts simulated by CLM are compared well with the satellite observations of Global Precipitation Climatology Project (GPCP). Both exhibit significant decreases in the region from 1980 to 2008. The CLM rainfalls also agree well with the available in-situ rainfall measurements during 1997 to 2007 from the Oklahoma Mesonet, which consist of 120 stations over the Oklahoma. For evaporation, currently there are no reliable direct observations during the time period studied. Limited satellite observations from the Princeton land surface data set indicate likely increase of evaporation. The soil moisture and temperature from SGP has records starting 1997, which is not enough to show the trend because of large variability. But both SRB and ISCCP surface net radiative flux from 1983 to 2008 shows an increasing trend. This could support the idea of increase in evaporation. The general decreases in precipitation and possible enhancements in evaporation would reduce land surface water storage. The reduced soil moisture could have considerable impact on land surface vegetation. For the Oklahoma region, this change would have a great potential in influence of regional agriculture and society.

    On April 23, 2011, a 1356-mm total length (TL), 39.8 kg bighead carp (Hypophthalmichthys nobilis) was brought to the Oklahoma Department of Wildlife Conservation. This specimen is the largest bighead carp recorded from Oklahoma, and it is near the maximum size reported from the United States. This specimen was estimated to be nine years old based on estimates from three different structures (pectoral fin ray, branchiostegal ray, and otolith). The age, together with past Oklahoma records of the species, indicates that there has been multiple introductions or undocumented reproduction of bighead carp in the Grand Lake basin.

  8. Estimated flood peak discharges on Twin, Brock, and Lightning creeks, Southwest Oklahoma City, Oklahoma, May 8, 1993

    USGS Publications Warehouse

    Tortorelli, R.L.

    1996-01-01

    The flash flood in southwestern Oklahoma City, Oklahoma, May 8, 1993, was the result of an intense 3-hour rainfall on saturated ground or impervious surfaces. The total precipitation of 5.28 inches was close to the 3-hour, 100-year frequency and produced extensive flooding. The most serious flooding was on Twin, Brock, and Lightning Creeks. Four people died in this flood. Over 1,900 structures were damaged along the 3 creeks. There were about $3 million in damages to Oklahoma City public facilities, the majority of which were in the three basins. A study was conducted to determine the magnitude of the May 8, 1993, flood peak discharge in these three creeks in southwestern Oklahoma City and compare these peaks with published flood estimates. Flood peak-discharge estimates for these creeks were determined at 11 study sites using a step-backwater analysis to match the flood water-surface profiles defined by high-water marks. The unit discharges during peak runoff ranged from 881 cubic feet per second per square mile for Lightning Creek at SW 44th Street to 3,570 cubic feet per second per square mile for Brock Creek at SW 59th Street. The ratios of the 1993 flood peak discharges to the Federal Emergency Management Agency 100-year flood peak discharges ranged from 1.25 to 3.29. The water-surface elevations ranged from 0.2 foot to 5.9 feet above the Federal Emergency Management Agency 500-year flood water-surface elevations. The very large flood peaks in these 3 small urban basins were the result of very intense rainfall in a short period of time, close to 100 percent runoff due to ground surfaces being essentially impervious, and the city streets acting as efficient conveyances to the main channels. The unit discharges compare in magnitude to other extraordinary Oklahoma urban floods.

  9. Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresholds in Oklahoma Streams

    Masoner, Jason R.; Haggard, Brian E.; Rea, Alan

    2002-01-01

    The U.S.Environmental Protection Agency has developed nutrient criteria using ecoregions to manage and protect rivers and streams in the United States. Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. The Oklahoma Water Resources Board uses a dichotomous process that stratifies streams using environmental characteristics such as stream order and stream slope. This process is called the Use Support Assessment Protocols, subchapter15. The Use Support Assessment Protocols can be used to identify streams threatened by excessive amounts of nutrients, dependant upon a beneficial use designation for each stream. The Use Support Assessment Protocols, subchapter 15 uses nutrient and environmental characteristic thresholds developed from a study conducted in the Netherlands, but the Oklahoma Water Resources Board wants to modify the thresholds to reflect hydrologic and ecological conditions relevant to Oklahoma streams and rivers. Environmental characteristics thought to affect impairment from nutrient concentrations in Oklahoma streams and rivers were determined for 798 water-quality sites in Oklahoma. Nutrient, chlorophyll, water-properties, and location data were retrieved from the U.S. Environmental Protection Agency STORET database including data from the U.S. Geological Survey, Oklahoma Conservation Commission, and Oklahoma Water Resources Board. Drainage-basin area, stream order, stream slope, and land-use proportions were determined for each site using a Geographic Information System. The methods, procedures, and data sets used to determine the environmental characteristics are described.

    1970-01-01

    An evaluation of the streamflow data available in Oklahoma has been made to provide guidelines for planning future data-collection programs. The basic steps in the evaluation procedure were (1) definition of the long-terms goals of the streamflow-data program in quantitative form, (2) examination and analysis of streamflow data to determine which goals have been met, and (3) consideration of alternate programs and techniques to meet the remaining goals. The study defines the individual relation between certain statistical streamflow characteristics and selected basin parameters. This relation is a multiple regression equation that could be used on a statewide basis to compute a selected natural-flow characteristic at any site on a stream. The study shows that several streamflow characteristics can be estimated within an accuracy equivalent to 10 years of record by use of a regression related to at least three climatic or basin parameters for any basin of 50 square miles or more. The study indicates that significant changes in the scope and character of the data-collection program would enhance the possibility of attaining the remaining goals. A streamflow-data program based on the guidelines developed in this study is proposed for the future.

The streams of Oklahoma are classified into two major drainage basins: the Arkansas River and the Red River and their tributaries. The attached analyses are arranged in geographical order for their respective drainage basins, with records listed in downstream order for stations on the main stem first, followed by the analyses for the tributaries. When available, the mean daily discharge is given for the analyses.

  14. Karst in Permian evaporite rocks of western Oklahoma

    SciTech Connect

    Johnson, K.S. )

    1993-02-01

    Bedded evaporites (gypsum and salt) of Permian age have been dissolved naturally by ground water to form a major evaporite-karst region in western Oklahoma. The Blaine Formation and associated evaporites comprise 100--800 ft of strata that dip gently into broad, structural basins. Outcropping gypsum, dolomite, and red-bed shales of the Blaine display typical karstic features, such as sinkholes, caves, disappearing streams, and springs. Large caves are developed in gypsum beds 10--30 ft thick at several places, and a major gypsum/dolomite karst aquifer provides irrigation water to a large region in southwestern Oklahoma, where salt layers above and below the Blaine Formation have been partly dissolved at depths of 30--800 ft below the land surface. Salt dissolution causes development of brine-filled cavities, into which overlying strata collapse, and the brine eventually is emitted at the land surface in large salt plains.

  3. Petroleum geology of the Palo Duro Basin, Texas Panhandle

    SciTech Connect

    Rose, P.R.

    1986-03-01

    The Palo Duro Basin, Permian Basin, Texas is an asymmetric, relatively shallow, intracratonic basin in the southern Texas Panhandle filled mostly by Mississippian, Pennsylvanian, and Permian sedimentary rocks. Although deeper and prolific prolific petroleum-producing basins adjoin it on the north (Anadarko Basin), south (Midland Basin), and east (Hardeman Basin), the Palo Duro Basin has produced remarkably small amounts of oil and gas to date. This is all the more noteworthy because the sedimentary sequence and rock types of the basin are similar to those of the adjacent basins. Analyses of the stratigraphic succession and structural configuration of the Palo Duro Basin suggest that adequate reservoir rocks, top-seals, and geologic structures are present. Most of the structures formed early enough to have trapped hydrocarbons if they were migrating in the rock column. Although additional work is under way to properly address the question of the petroleum source rocks, generation, and migration, the general absence of production in the basin may relate to an overall deficiency in hydrocarbon generation within the basin. Geologic information in this report will form part of the basis for further analysis and conclusions on hydrocarbon potential in the Palo Duro Basin.

  5. Simpson-Arbuckle contact revisited in Northwest Oklahoma County, Oklahoma

    Allison, M.D.; Allen, R.W.

    1995-09-01

    The Joins Formation, the lowermost formation of the Simpson Group, is traditionally the least studied or understood of the Simpson formations. The Joins, not known to produce hydrocarbons in central Oklahoma, is frequently overlooked by those more interested in the productive Simpson formations above and the Arbuckle carbonates below. In a study of the lower Simpson to upper Arbuckle interval in northwestern Oklahoma County, Oklahoma, the Joins Formation was found to be present. The central Oklahoma section consists of interbedded gray, olive gray and green splintery moderately waxy shale, cream to light gray homogeneous microcrystallin dolomite, and microcrystalline to fine crystalline fossiliferous slightly glauconitic well cemented sandstones are also noted. The entire Joins Formation is moderately to very fossiliferous; primarily consisting of crinoids, ostracods, brachiopods, and trilobites. The ostracod fauna closely resembles and correlates with the Arbuckle Mountain section, which has been extensively studied over the years by such authors as Taff, Ulrich and Harris. Beneath the Joins in this area is a normal section of Arbuckle dolomites. Due to the absence of a basal sand in the Joins the separation of the Joins and Arbuckle, utilizing electric logs only, is frequently tenuous. In comparison with the Arbuckle, the Joins tends to have higher gamma ray and S.P. values. Other tools, such as resistivity, bulk density and photoelectric (PE), are frequently inconclusive. For geologists studying the Simpson-Arbuckle contact in central Oklahoma, the presence or absence of the Joins Formation is best determined through conventional lithologic and palenontologic sample identification techniques. Once this has been done, correlation of electric logs with this type log is possible for the local area.

    1974-01-01

    Annual peak discharges and basin and climatic characteristics, computed during the 10 years of the project, are summarized for 103 small-stream sites in Oklahoma. The U.S. Geological Survey rainfall-runoff model was calibrated for six small watersheds in Oklahoma. Calibration results, discussed in this report, indicate that the rainfall-runoff model can be used to extend the length of flood records for small watersheds in Oklahoma. Records from four small watersheds were extended by the model and synthetic frequency curves were computed for these sites to show applicability of the model. Further analyses and data are needed before the model can be applied statewide to compute improved estimating equations.

  15. Submarine-fan sedimentation, Ouachita Mountains, Arkansas and Oklahoma

    SciTech Connect

    Moiola, R.J.; Shanmugam, G.

    1984-09-01

    More than 10,000 m (32,808 ft) of interbedded sandstones and shales comprise the Upper Mississippian and Lower Pennsylvanian flysch succession (Stanley, Jackfork, Johns Valley, Atoka) in the Ouachita Mountains of Arkansas and Oklahoma. Deposited primarily by turbidity current and hemipelagic processes in bathyal and abyssal water depths, these strata formed major submarine-fan complexes that prograded in a westward direction along the axis of an elongate remnant ocean basin that was associated with the collision and suturing of the North American and African-South American plates. A longitudinal fan system is visualized as the depositional framework for these strata, which were deposited in a setting analogous to the modern Bengal fan of the Indian Ocean. Facies analysis of the Jackfork formation indicates that inner fan deposits are present in the vicinity of Little Rock, Arkansas; middle fan channel and interchannel deposits occur at DeGray Dam and Friendship, Arkansas; and outer fan depositional-lobe deposits are present in southeastern Oklahoma. Boulder-bearing units (olistostromes), many with exotic clasts, were shed laterally into the Ouachita basin. They occur throughout the flysch succession and in all fan environments (i.e., inner, middle, and outer). This relationship may serve as a useful criterion for recognizing analogous longitudinal fan systems in the rock record.

  16. The Deese and Collings ranch conglomerates of the Arbuckle Mountains, Oklahoma: Evidence of strike-slip movement during the deformation stage of the southern Oklahoma Aulacogen

    It has been widely recognized that the Pennsylvanian conglomerates of the Arbuckle Mountains, Oklahoma, record the deformation stage of the Southern Oklahoma Aulacogen. Two of these units are the Desmoinesian Deese Conglomerate, exposed in the Mill Creek Syncline area between the Reagan and Mill Creek fault zones, and the Middle Virgilian Collings Ranch Conglomerate, exposed along the Washita Valley fault zone in the Turner Falls area. The authors investigated clast size, geometry, and content, primary sedimentary structures, petrography, petrology, and diagenesis of the two conglomerate units, as well as the geometric relationship of their basins with nearby faults. Their evidence suggests that the two conglomerates were deposited as alluvial fans in basins formed by strike-slip movements. The Collings Ranch Conglomerate was deposited in a basin formed as the result of left-stepping along the nearby Washita Valley strike-slip fault zone. The Deese Conglomerate was deposited in a basin formed due to the combined effect of strike-slip and dip-slip movements along the Reagan and Mill Creek fault zones. In the Collings Ranch basin, the deposition was accomplished primarily by channel-fill and sieve deposits in the proximal region of the fan. The Deese Conglomerate was deposited as an alluvial fan or fans which included several channel deposits while, in the deeper parts of the basin, fine-grained materials and limestones were deposited. These observations and their possible interpretations suggest that the Washita Valley, Mill Creek, and Reagan fault zones have experienced substantial strike-slip movement during the deformation stage of the Southern Oklahoma Aulacogen.

  17. Changes in streamflow and summary of major-ion chemistry and loads in the North Fork Red River basin upstream from Lake Altus, northwestern Texas and western Oklahoma, 1945-1999

    USGS Publications Warehouse

    Smith, S. Jerrod; Wahl, Kenneth L.

    2003-01-01

    Upstream from Lake Altus, the North Fork Red River drains an area of 2,515 square miles. The quantity and quality of surface water are major concerns at Lake Altus, and water-resource managers and consumers need historical information to make informed decisions about future development. The Lugert-Altus Irrigation District relies on withdrawals from the lake to sustain nearly 46,000 acres of agricultural land. Kendall's tau tests of precipitation data indicated no statistically significant trend over the entire 100 years of available record. However, a significant increase in precipitation occurred in the last 51 years. Four streamflow-gaging stations with more than 10 years of record were maintained in the basin. These stations recorded no significant trends in annual streamflow volume. Two stations, however, had significant increasing trends in the base-flow index, and three had significant decreasing trends in annual peak flows. Major-ion chemistry in the North Fork Red River is closely related to the chemical composition of the underlying bedrock. Two main lithologies are represented in the basin upstream from Lake Altus. In the upper reaches, young and poorly consolidated sediments include a range of sizes from coarse gravel to silt and clay. Nearsurface horizons commonly are cemented as calcium carbonate caliche. Finer-grained gypsiferous sandstones and shales dominate the lower reaches of the basin. A distinct increase in dissolved solids, specifically sodium, chloride, calcium, and sulfate, occurs as the river flows over rocks that contain substantial quantities of gypsum, anhydrite, and dolomite. These natural salts are the major dissolved constituents in the North Fork Red River.

    1993-07-01

    The US Nuclear Regulatory Commission has established rigorous guidelines that must be adhered to before a permit to construct a nuclear-power plant is granted to an applicant. Local as well as regional seismicity and structural relationships play an integral role in the final design criteria for nuclear power plants. The existing historical record of seismicity is inadequate in a number of areas of the Midcontinent region because of the lack of instrumentation and (or) the sensitivity of the instruments deployed to monitor earthquake events. The Nemaha Uplift/Midcontinent Geophysical Anomaly is one of five principal areas east of the Rocky Mountain front that has a moderately high seismic-risk classification. The Nemaha uplift, which is common to the states of Oklahoma, Kansas, and Nebraska, is approximately 415 miles long and 12-14 miles wide. The Midcontinent Geophysical Anomaly extends southward from Minnesota across Iowa and the southeastern corner of Nebraska and probably terminates in central Kansas. A number of moderate-sized earthquakes--magnitude 5 or greater--have occurred along or west of the Nemaha uplift. The Oklahoma Geological Survey, in cooperation with the geological surveys of Kansas, Nebraska, and Iowa, conducted a 5-year investigation of the seismicity and tectonic relationships of the Nemaha uplift and associated geologic features in the Midcontinent. This investigation was intended to provide data to be used to design nuclear-power plants. However, the information is also being used to design better large-scale structures, such as dams and high-use buildings, and to provide the necessary data to evaluate earthquake-insurance rates in the Midcontinent.

  17. Prediction of pressure depletion from wireline and mud logs, Golden Trend field, Garvin County, Oklahoma

    SciTech Connect

    1987-08-01

    The Golden Trend, a giant oil field encompassing several overlapping Pennsylvanian stratigraphic traps on the eastern flank of the Anadarko basin, has undergone a resurgence in the 1980s with deeper drilling for pre-Pennsylvanian targets. Approximately 200 new wells in and near the Antioch Southwest, Panther Creek, and Elmore Northeast waterflood units (T2, 3N, R2, 3W) have encountered evidence of undrained reserves in both established and new pay intervals of Pennsylvanian Hart and Gibson sandstones. Although all porous Hart and Gibson sandstones in the study area were originally oil bearing, evaluation of the state of depletion is necessary for planning future recompletions to these reservoirs. In general, wireline and mud logs over intervals with known production histories exhibit characteristics suggestive of pressure depletion, even in areas of old waterfloods. The most consistent parameters correlating to low reservoir pressure are lost circulation, lack of an increase in penetration rate when drilling porous sandstone, excessive gas effect on neutron-density logs, and low methane and total gas levels on the mud logs. The resistivity invasion profile also reflects lower pressure, but is subtle. The SP curve and gas composition on the mud log do not vary substantially as a function of pressure. Visual sample shows are slightly weaker in depleted sandstones, but are less reliable, owing to dependence on reservoir quality and variations between geologists on oral descriptions of show quality.

  1. Changes in chemical quality of the Arkansas River in Oklahoma and Arkansas (1946-52)

    USGS Publications Warehouse

    Dover, T.B.; Geurin, J.W.

    1953-01-01

    Systematic chemical quality-of-water investigations have been carried on in both Oklahoma and Arkansas by the Geological Survey in cooperation with State and Federal agencies during the past several years. Results of the Survey's quality-of-water investigations are usually published in the annual Water-Supply Papers. However, as the Geological Survey has made no sediment investigations in the Arkansas River Basin in Oklahoma and Arkansas, the published data do not include information on sediment concentrations or loads. This report attempts to summarize information collected to date in the Arkansas River Basin of the two States, and to show as clearly as possible from present information how the chemical quality of water in the Arkansas River changes downstream from the Oklahoma-Kansas State line to its confluence with the Mississippi River, and how it is affected by tributary inflows. Additional information is being collected and further studies are planned. Hence, the conclusions reached herein may be modified by more adequate information at a later date. The Arkansas River enters Oklahoma near Newkirk on the northern boundary just east of the 97th meridian, crosses the State in a general southeasterly direction flowing past Tulsa, enters Arkansas at its western boundary north of the 35th parallel near Fort Smith, still flowing in a general southeasterly direction past Little Rock near the center of the State, and empties into the Mississippi River east of Dumas. The Arkansas River is subject to many types of pollution downstream from the Oklahoma-Kansas State line, and its inferior quality along with an erratic flow pattern has caused it to be largely abandoned as a source of municipal and industrial water supply. At the present time, the Arkansas River is not directly used as a source of public supply in any part of the basin in either Oklahoma or Arkansas. In general, the river water increases in chemical concentration downstream from the Oklahoma-Kansas State line to Tulsa, due mainly to tributary inflow from the Salt Fork Arkansas River and the Cimarron River, both streams being sources of large amounts of both natural and artificial pollution. A decrease in chemical concentration is noted downstream from Tulsa due to tributary inflow from the Verdigris, Neosho, and Illinois rivers with an increase in chemical concentration then noted due to tributary inflow from the Canadian River which is largely artificial pollution. A steady decrease in concentration is then noted as the river progresses through Arkansas to the Mississippi River, as all major tributaries below the Canadian River have a dilution effect upon the chemical concentration of the Arkansas River water. Proposals for storage and regulating reservoirs on the Arkansas River in both Oklahoma and Arkansas have been made by the Corps of Engineers and others. Additional proposals are being considered in the present Arkansas-White-Red River Basin Inter-Agency Committee studies. If constructed, these reservoirs will provide an opportunity for control of flow and beneficial use of Arkansas River water, both at and downstream from these sites. Impoundment alone will greatly reduce the extremes in water quality, and by reasonable control of municipal and industrial wastes, the water would be comparable in quality to many existing basin municipal and industrial supplies.

  2. Watershed boundaries and digital elevation model of Oklahoma derived from 1:100,000-scale digital topographic maps

    Cederstrand, J.R.; Rea, A.H.

    1995-01-01

    This document provides a general description of the procedures used to develop the data sets included on this compact disc. This compact disc contains watershed boundaries for Oklahoma, a digital elevation model, and other data sets derived from the digital elevation model. The digital elevation model was produced using the ANUDEM software package, written by Michael Hutchinson and licensed from the Centre for Resource and Environmental Studies at The Australian National University. Elevation data (hypsography) and streams (hydrography) from digital versions of the U.S. Geological Survey 1:100,000-scale topographic maps were used by the ANUDEM package to produce a hydrologically conditioned digital elevation model with a 60-meter cell size. This digital elevation model is well suited for drainage-basin delineation using automated techniques. Additional data sets include flow-direction, flow-accumulation, and shaded-relief grids, all derived from the digital elevation model, and the hydrography data set used in producing the digital elevation model. The watershed boundaries derived from the digital elevation model have been edited to be consistent with contours and streams from the U.S. Geological Survey 1:100,000-scale topographic maps. The watershed data set includes boundaries for 11-digit Hydrologic Unit Codes (watersheds) within Oklahoma, and 8-digit Hydrologic Unit Codes (cataloging units) outside Oklahoma. Cataloging-unit boundaries based on 1:250,000-scale maps outside Oklahoma for the Arkansas, Red, and White River basins are included. The other data sets cover Oklahoma, and where available, portions of 1:100,000-scale quadrangles adjoining Oklahoma.

    The value of Oklahoma nonfuel mineral production was nearly $252.6 million in 1992, a decrease of $22.9 million from that reported to the U.S. Bureau of Mines by State mineral producers in 1991. The value of the top three commodities produced, crushed stone, portland cement, and construction sand and gravel, exceeded $168.8 million and comprised almost 67% of the State's total nonfuel mineral value. Although rebounding from the recessionary period, the growth curve for several minerals produced in the State was minimal, and for several others it moved downward. Oklahoma ranked 35th nationally in total nonfuel mineral value. The State ranked 26th nationally in the production of industrial minerals, contributing about 1.38% of the $20.7 billion revenues received. Oklahoma ranked first in the Nation in crude gypsum production, second in the production of tripoli, and was the only domestic source of iodine.

    1997-01-01

    ARC/INFO export files The data sets in this report include digitized aquifer boundaries and maps of hydraulic conductivity, recharge, and ground-water level elevation contours for the Central Oklahoma aquifer in central Oklahoma. This area encompasses all or part of Cleveland, Lincoln, Logan, Oklahoma, Payne, and Pottawatomie Counties. The Central Oklahoma aquifer includes the alluvial and terrace deposits along major streams, the Garber Sandstone and Wellington Formations, and the Chase, Council Grove, and Admire Groups. The Quaternary-age alluvial and terrace deposits consist of unconsolidated clay, silt, sand, and gravel. The Permian-age Garber Sandstone and Wellington Formations consist of sandstone with interbedded siltstone and mudstone. The Permian-age Chase, Council Grove, and Admire Groups consist of sandstone, shale, and thin limestone. The Central Oklahoma aquifer underlies about 3,000 square miles of central Oklahoma where the aquifer is used extensively for municipal, industrial, commercial, and domestic water supplies. Most of the usable ground water within the aquifer is from the Garber Sandstone and Wellington Formations. Substantial quantities of usable ground water also are present in the Chase, Council Grove, and Admire Groups, and in alluvial and terrace deposits associated with the major streams. The aquifer boundaries, hydraulic conductivity and recharge values, and ground-water level elevation contours are from previously published reports.

  17. A century of induced earthquakes in Oklahoma?

    USGS Publications Warehouse

    Hough, Susan E.; Page, Morgan T.

    2015-01-01

    Seismicity rates have increased sharply since 2009 in the central and eastern United States, with especially high rates of activity in the state of Oklahoma. Growing evidence indicates that many of these events are induced, primarily by injection of wastewater in deep disposal wells. The upsurge in activity has raised two questions: What is the background rate of tectonic earthquakes in Oklahoma? How much has the rate varied throughout historical and early instrumental times? In this article, we show that (1) seismicity rates since 2009 surpass previously observed rates throughout the twentieth century; (2) several lines of evidence suggest that most of the significant earthquakes in Oklahoma during the twentieth century were likely induced by oil production activities, as they exhibit statistically significant temporal and spatial correspondence with disposal wells, and intensity measurements for the 1952 El Reno earthquake and possibly the 1956 Tulsa County earthquake follow the pattern observed in other induced earthquakes; and (3) there is evidence for a low level of tectonic seismicity in southeastern Oklahoma associated with the Ouachita structural belt. The 22 October 1882 Choctaw Nation earthquake, for which we estimate Mw 4.8, occurred in this zone.

  4. Oil and gas fields of Oklahoma

    Burchfield, M.R.

    1984-04-01

    At the end of April 1983, there were 3088 active oil and/or gas fields in the state of Oklahoma, as well as 32 officially named abandoned fields, according to the Nomenclature Committee of the Mid-Continent Oil and Gas Association. Oil and/or gas fields are located in 73 of Oklahoma's 77 countries, and represent over 4 million acres (1.5 million ha.) in surface area. The Oklahoma Geological Survey has prepared a new, up-to-date map of all officially named oil and/or gas fields in the state, at a scale of 1:500,000. Each field is outlined, assigned an index number for reference, and designated by color code as either an oil field, gas field, or combination oil and gas field. As an improvement over oil and gas field maps available from commercial sources, the OGS has attempted to define better the geographic boundaries of each field. An alphabetical listing of all fields with their reference numbers and locations is featured on the map, along with a listing of smaller fields that have been combined into Oklahoma's major oil and gas ''trends''. The map is designed for use as a reference by all oil and gas professionals in the state. The OGS oil and gas field map has been prepared in conjunction with the development of a computerized oil and gas field file for Oklahoma. Production of updated versions of the map in future years will be facilitated by digitization of information shown on the present map.

  5. Stratigraphic variations in the Carboniferous section across the Arkansas-Oklahoma State Line Arch

    NASA Astrophysics Data System (ADS)

    Engelhardt, Tyler D.

    The State Line Arch is represented by a structural high that trends through the study area in a loose alignment with the Arkansas-Oklahoma state line. Evidence of the arch extending further to the north includes a structural high and stratigraphic variation at an outcrop on Highway 59 near Evansville Mountain in Crawford County, Arkansas. The exact timing of the formation of the arch remains undetermined, but upper Devonian thinning at the top of the arch indicates the structure is pre-Mississippian. The reason for the development of the arch is poorly understood, but evidence linking Mississippian-aged Waulsortian mounds to Precambrian Spavinaw granite structures of northeastern Oklahoma and southwestern Missouri suggests Precambrian basement structures may extend into the study area. The structural nature of the arch provided an environment favorable to carbonate build-up during deposition of the Mississippian interval. A previously unidentified limestone unit measuring 175 feet thick likely represents the transgressive phase of a transgressive-regressive sequence responsible for the deposition of the Mayes Group of northeastern Oklahoma. Growth on the downthrown side of the Muldrow-Mulberry Fault system may indicate earlier movement than previous studies have suggested on the east-west trending normal faults of the Arkoma Basin. A possible roll-over anticline structure may exist to the south of the Muldrow-Mulberry fault system.

    The lower member of the Pennsylvanian Atoka Formation exposed in the Ouachita Mountains of Oklahoma and Arkansas is part of a thick (more than 10,000 m or 32,800 ft) turbidite sequence deposited in a remnant ocean basin (the Ouachita geosyncline) during the Carboniferous. Paleocurrent data indicate a predominantly longitudinal sediment dispersal pattern westward down the basin axis. The absence of deposits of major depositional lobes and the extensive development (both vertically and laterally) of a channelized (distributary channel) fan environment suggest that current submarine-fan models are not generally applicable to this deposit.

  8. Getting to the source: aeolian influx to the Permian Delaware basin region

    Kocurek, Gary; Kirkland, Brenda L.

    1998-05-01

    Although an aeolian origin for the siliciclastics of the Permian (Guadalupian) Delaware and adjacent basins and shelf has been recognized, their source has remained elusive. An Ancestral Rockies source to the west and northwest has been traditionally favored. We propose instead that these sediments were derived from aeolian systems to the northeast and represented by the Whitehorse Group in the Anadarko Basin. This hypothesis is based upon (1) recognition of the aeolian nature of the Whitehorse, (2) regional correlation of the Whitehorse Group with portions of the Artesia Group, (3) paleoclimatic model-predicted and measured southwestward sediment transport for the Whitehorse, and (4) a proposed transport corridor over emergent mudflats along the northern margins of basisins in the Texas Panhandle and onto the New Mexico shelf. Potentially, a Whitehorse-Artesia link could show the formation of this mixed carbonate/siliciclastic system as the result of the interactions of diverse and distant environmental systems under eustatic and climatic forcing factors.

  9. Hydrologic Drought of Water Year 2006 Compared with Four Major Drought Periods of the 20th Century in Oklahoma

    USGS Publications Warehouse

    Tortorelli, Robert L.

    2008-01-01

    Water Year 2006 (October 1, 2005, to September 30, 2006) was a year of extreme hydrologic drought and the driest year in the recent 2002-2006 drought in Oklahoma. The severity of this recent drought can be evaluated by comparing it with four previous major hydrologic droughts, water years 1929-41, 1952-56, 1961-72, and 1976-81. The U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, completed an investigation to summarize the Water Year 2006 hydrologic drought and compare it to the four previous major hydrologic droughts in the 20th century. The period of water years 1925-2006 was selected as the period of record because before 1925 few continuous record streamflow-gaging sites existed and gaps existed where no streamflow-gaging sites were operated. Statewide annual precipitation in Water Year 2006 was second driest and statewide annual runoff in Water Year 2006 was sixth driest in the 82 years of record. Annual area-averaged precipitation totals by the nine National Weather Service Climate Divisions from Water Year 2006 are compared to those during four previous major hydrologic droughts to show how rainfall deficits in Oklahoma varied by region. Only two of the nine climate divisions, Climate Division 1 Panhandle and Climate Division 4 West Central, had minor rainfall deficits, while the rest of the climate divisions had severe rainfall deficits in Water Year 2006 ranging from only 65 to 73 percent of normal annual precipitation. Regional streamflow patterns for Water Year 2006 indicate that Oklahoma was part of the regionwide below-normal streamflow conditions for Arkansas-White-Red River Basin, the sixth driest since 1930. The percentage of long-term stations in Oklahoma (with at least 30 years of record) having below-normal streamflow reached 80 to 85 percent for some days in August and November 2006. Twelve long-term streamflow-gaging sites with periods of record ranging from 62 to 78 years were selected to show how streamflow deficits varied by region. The hydrologic drought worsened going from north to south in Oklahoma, ranging from 45 percent in the north, to just 14 percent in east-central Oklahoma, and 20 percent of normal annual streamflow in the southwest. The low streamflows resulted in only 86.3 percent of the statewide conservation storage available at the end of the water year in major reservoirs, and 7 to 47 percent of hydroelectric power generation at sites in Oklahoma in Calendar Year 2005.

    Digital-elevation models, field survey measurements, hydraulic data, and hydrologic data (U.S. Geological Survey streamflow-gaging stations North Canadian River below Lake Overholser near Oklahoma City, Okla. [07241000], and North Canadian River at Britton Road at Oklahoma City, Okla. [07241520]), were used as inputs for the one-dimensional dynamic (unsteady-flow) models using Hydrologic Engineering Centers River Analysis System (HEC–RAS) software. The modeled flood elevations were exported to a geographic information system to produce flood-inundation maps. Water-surface profiles were developed for a 75-percent probable maximum flood dam-breach scenario and a sunny-day dam-breach scenario, as well as for maximum flood-inundation elevations and flood-wave arrival times at selected bridge crossings. Points of interest such as community-services offices, recreational areas, water-treatment plants, and wastewater-treatment plants were identified on the flood-inundation maps.

    Hantavirus Pulmonary Syndrome (HPS) was first recognized in 1993. Through July 6, 2005, 396 cases have been reported in the US, including 50 from Kansas, Texas, and Oklahoma. We report the second case of HPS in Oklahoma and present data from rodent testing to support the presence of hantaviruses across Oklahoma. We examined Oklahoma death certificates for 1999-2003 for possible unreported HPS cases. The rate of death in young adults 15-49 years due to acute respiratory distress syndrome was 69% higher and the death rate due to unspecified respiratory failure was three times higher in the grassland area of Oklahoma as compared to the non-grassland. It appears the highest risk of HPS is in the Oklahoma grasslands but Sin Nombre virus is present in the non-grassland area as well. We request physician collaboration in detection and reporting of HPS cases and present brief recommendations for prevention. PMID:17557601

    In Oklahoma, the infant mortality rate is higher than the national rate. Fetal Infant Mortality Review (FIMR) is an effective perinatal systems intervention. FIMR gathers information from medical, social, and community sources taking a comprehensive look at how well these systems are serving women and infants. It is important to understand that FIMR is a method to develop community-based plans to reduce fetal and infant mortality. It is not a quick-fix solution to a complex problem, a research study, an institutional review, or a system for assigning blame or responsibility for a death. FIMR has been instrumental in identifying what health care providers, community leaders, and citizens can do to improve the health and lives of babies in Oklahoma. Key steps include: (1.) Data abstraction (2.) A home interview (3.) A review of individual case summaries (4.) Development of community-based solutions and interventions designed to improve service systems and resources PMID:25790593

  16. Basin and range-age reactivation of the ancestral Rocky Mountains in Texas Panhandle: evidence from Ogallala Formation

    SciTech Connect

    Budnik, R.T.

    1984-04-01

    The Ogallala Formation (Neogene) is a widespread syntectonic alluvial apron that was shed eastward from the Rio Grande rift and related uplifts in Colorado and New Mexico during Basin and Range extension. In the Texas Panhandle, the Ogallala completely buried Ancestral Rocky Mountain (Pennsylvanian) structures. Renewed movement on these older structures during the Neogene influenced the thickness and facies distribution of the Ogallala. The Ogallala thickens into the Palo Duro, Dalhart, and Anadarko basins. Major distributary channels on Ogallala alluvial fans coincide with the axes of these basins, whereas major interchannel areas overlie intervening uplifts. Second-order structures subtly influenced the unit as well. For example, the Carson basin, a Pennsylvanian rhomb graben along the Amarillo uplift, the Ogallala is over 250 m (820 ft) thick compared with 90 m (275 ft) in adjacent areas. Within the Palo Duro basin, local highs controlled the distribution of thin, interchannel flood-basin and lacustrine deposits. Thicker, braided-stream channel deposits follow local lows. Later movement on the Amarillo uplift broadly folded the Ogallala. The southern high plains surface subtly reflects basement structure, with topographic highs overlying basement highs, suggesting post-Ogallala deformation within the Palo Duro basin. The Amarillo uplift is approximately perpendicular to the Rio Grande rift and parallel to the direction of Basin and Range extension. Thus, the stress field that produced the rift may have caused strike-slip movement and reactivation of the Carson basin along the Amarillo uplift.

    1982-04-01

    Uranium resources of the Lawton Quadrangle, Oklahoma and Texas, were evaluated to a depth of 1500 m using National Uranium Resource Evaluation criteria. Five areas of uranium favorability were delineated. Diagenetically altered, quartzose and sublithic, eolian and marginal-marine sandstones of the Permian Rush Springs Formation overlying the Cement Anticline are favorable for joint-controlled deposits in sandstone, non-channel-controlled peneconcordant deposits, and Texas roll-front deposits. Three areas contain lithologies favorable for channel-controlled peneconcordant deposits: arkosic sandstones and granule conglomerates of the Permian Post Oak Conglomerate south of the Wichita Mountains; subarkosic and sublithic Lower Permian fluvio-deltaic and coastal-plain sandstones of the eastern Red River Valley; and subsurface arkosic, subarkosic, and sublithic alluvial-fan and fan-delta sandstones of the Upper Pennsylvanian-Lower Permian sequence in the eastern Hollis Basin. The coarse-grained facies of the Cambrian Quanah Granite and genetically related aplite and pegmatite dikes in the Wichita Mountains are favorable for orthomagmatic and autometasomatic deposits, respectively.

  18. Heat flow in Oklahoma and the south central United States

    NASA Astrophysics Data System (ADS)

    Cranganu, Constantin; Lee, Youngmin; Deming, David

    1998-11-01

    We report 23 new heat flow values in the state of Oklahoma and combine these with previously reported values to create heat flow maps of Oklahoma and the central United States. In general, thermal gradients increase from southwestern Oklahoma (minimum, 14C km-1) to northeastern Oklahoma (maximum, 42C km-1); the mean thermal gradient in central Oklahoma is 31C km-1. We made 1498 thermal-conductivity measurements on drill cuttings from oil and gas wells. Heat flow in Oklahoma varies between 22 and 86 m W m-2; the average is about 50 m W m-2. Heat flow is relatively low (30-40 m W m-2) in southwest Oklahoma and is relatively high (70-80 m W m-2) in one section of east central Oklahoma. We also report 27 new estimations of radioactive heat production in basement rocks and combine these with 22 previously published data to create a map of basement heat production in Oklahoma. Heat production values range from 1.1 to 3.5 ?W m-3, with an average of 2.5 ?W m-3. Geologic evidence suggests that the present-day thermal regime is not significantly affected by sedimentation, erosion, or metamorphic/igneous activity and is essentially in a near steady state condition. Heat flow in Oklahoma appears to be largely controlled by heat production in basement rocks, although the correlation between heat flow and heat production is not strong. An area of high heat flow (70-80 m W m-2) in east central Oklahoma may be related to regional groundwater flow through the Arbuckle-Simpson aquifer.

    The DOE EPSCoR implementation grant, with the support from the State of Oklahoma and from the three universities, Oklahoma State University, University of Oklahoma and Langston University, resulted in establishing of the Oklahoma Center for High Energy Physics (OCHEP) in 2004. Currently, OCHEP continues to flourish as a vibrant hub for research in experimental and theoretical particle physics and an educational center in the State of Oklahoma. All goals of the original proposal were successfully accomplished. These include foun- dation of a new experimental particle physics group at OSU, the establishment of a Tier 2 computing facility for the Large Hadron Collider (LHC) and Tevatron data analysis at OU and organization of a vital particle physics research center in Oklahoma based on resources of the three universities. OSU has hired two tenure-track faculty members with initial support from the grant funds. Now both positions are supported through OSU budget. This new HEP Experimental Group at OSU has established itself as a full member of the Fermilab D0 Collaboration and LHC ATLAS Experiment and has secured external funds from the DOE and the NSF. These funds currently support 2 graduate students, 1 postdoctoral fellow, and 1 part-time engineer. The grant initiated creation of a Tier 2 computing facility at OU as part of the Southwest Tier 2 facility, and a permanent Research Scientist was hired at OU to maintain and run the facility. Permanent support for this position has now been provided through the OU university budget. OCHEP represents a successful model of cooperation of several universities, providing the establishment of critical mass of manpower, computing and hardware resources. This led to increasing Oklahoma’s impact in all areas of HEP, theory, experiment, and computation. The Center personnel are involved in cutting edge research in experimental, theoretical, and computational aspects of High Energy Physics with the research areas ranging from the search for new phenomena at the Fermilab Tevatron and the CERN Large Hadron Collider to theoretical modeling, computer simulation, detector development and testing, and physics analysis. OCHEP faculty members participating on the D0 collaboration at the Fermilab Tevatron and on the ATLAS collaboration at the CERN LHC have made major impact on the Standard Model (SM) Higgs boson search, top quark studies, B physics studies, and measurements of Quantum Chromodynamics (QCD) phenomena. The OCHEP Grid computing facility consists of a large computer cluster which is playing a major role in data analysis and Monte Carlo productions for both the D0 and ATLAS experiments. Theoretical efforts are devoted to new ideas in Higgs bosons physics, extra dimensions, neutrino masses and oscillations, Grand Unified Theories, supersymmetric models, dark matter, and nonperturbative quantum field theory. Theory members are making major contributions to the understanding of phenomena being explored at the Tevatron and the LHC. They have proposed new models for Higgs bosons, and have suggested new signals for extra dimensions, and for the search of supersymmetric particles. During the seven year period when OCHEP was partially funded through the DOE EPSCoR implementation grant, OCHEP members published over 500 refereed journal articles and made over 200 invited presentations at major conferences. The Center is also involved in education and outreach activities by offering summer research programs for high school teachers and college students, and organizing summer workshops for high school teachers, sometimes coordinating with the Quarknet programs at OSU and OU. The details of the Center can be found in http://ochep.phy.okstate.edu.

  6. More wells will expand knowledge of Knox group, Black Warrior basin

    SciTech Connect

    Raymond, D.E. )

    1991-05-20

    The Arbuckle group of the Arkoma, Ardmore, and Anadarko basins was essentially untested in 1986. This paper reports that in these basins, shallower Pennsylvanian reservoirs were easy to reach and more economical to develop. The general consensus was that if a karstic reservoir was not present at the top of the Arbuckle group then there was no potential for oil and gas. Today the story is different; production zones are being found throughout the Arbuckle group, and drilling has been as deep as 28,000 ft. The Black Warrior basin is in a similar setting to the Arkoma, it is a foreland basin that has produced from multiple Mississippian and Pennsylvanian horizons at shallow depths. The Knox carbonate is present in a similar structural setting to that of the Arbuckle group at depths generally above 15,000 ft. In addition, Alabama is even more fortunate in that the buried Appalachian fold and thrust belt along the southern boundary of the basin also provides additional Knox targets with great promise. In this area Knox dolomites are fractured and folded and are juxtaposed by thrust faulting against Mississippian and Pennsylvanian rocks that are excellent sources of oil and gas. Therefore, the Knox is essentially untested in the Black Warrior basin.

  7. Biological assessment of environmental flows for Oklahoma

    Fisher, William L.; Seilheimer, Titus S.; Taylor, Jason M.

    2012-01-01

    Large-scale patterns in fish assemblage structure and functional groups are influenced by alterations in streamflow regime. In this study, we defined an objective threshold for alteration for Oklahoma streams using a combination of the expected range of 27 flow indices and a discriminant analysis to predict flow regime group. We found that fish functional groups in reference flow conditions had species that were more intolerant to flow alterations and preferences for stream habitat and faster flowing water. In contrast, altered sites had more tolerant species that preferred lentic habitat and slower water velocity. Ordination graphs of the presence and functional groups of species revealed an underlying geographical pattern roughly conforming to ecoregions, although there was separation between reference and altered sites within the larger geographical framework. Additionally, we found that reservoir construction and operation significantly altered fish assemblages in two different systems, Bird Creek in central Oklahoma and the Kiamichi River in southeastern Oklahoma. The Bird Creek flow regime shifted from a historically intermittent stream to one with stable perennial flows, and changes in fish assemblage structure covaried with changes in all five components of the flow regime. In contrast, the Kiamichi River flow regime did not change significantly for most flow components despite shifts in fish assemblage structure; however, most of the species associated with shifts in assemblage structure in the Kiamichi River system were characteristic of lentic environments and were likely related more to proximity of reservoirs in the drainage system than changes in flow. The spatial patterns in fish assemblage response to flow alteration, combined with different temporal responses of hydrology and fish assemblage structure at sites downstream of reservoirs, indicate that interactions between flow regime and aquatic biota vary depending on ecological setting. This supports the notion that regional variation in natural flow regimes could affect the development of flow recommendations.

    The Fort Smith quadrangle in western Arkansas and eastern Oklahoma overlies thick Paleozoic sediments of the Arkoma Basin. These Paleozoics dominate surface exposure except where covered by Quaternary Alluvial materials. Examination of available literature shows no known uranium deposits (or occurrences) within the quadrangle. Seventy-five groups of uranium samples were defined as anomalies and are discussed briefly. None were considered significant, and most appeared to be of cultural origin. Magnetic data show character that suggest structural and/or lithologic complexity, but imply relatively deep-seated sources.

  9. Development of regression models to estimate flow duration statistics at ungaged streams in Oklahoma using a regional approach

    2009-01-01

    Multiple-regression analysis was used to develop equations for estimating annual and seasonal flow-duration statistics at ungaged streams in and near Oklahoma that are not substantially affected by human alteration. Ordinary least-squares and left-censored (Tobit) multiple-regression techniques were used to develop equations that relate these statistics, from continuous streamflow data at gaged locations with 10 or more years of record, to physical and climatic basin characteristics. Separate equations were developed to estimate these statistics for stations within similar hydrologic and geologic regions. Use of separate regressions by region substantially improved the accuracy of the estimate for streams in eastern and central Oklahoma when compared with estimating equations developed for the entire State, especially for regressions estimating lower flow duration values. For all regions, the equations were more reliable for estimating higher flow duration values. The accuracy of regressions for estimating flow duration statistics in western Oklahoma was very poor, especially for lower flow duration values. ?? 2009 ASCE.

    Ferebee, C.D.; Tapp, J.B. )

    1989-08-01

    The authors document fracture density and spacing associated with the Washita Valley fault, a major strike-slip fault. The Washita Valley fault strikes northwest-southeast with up to 80 mi of exposure in southern Oklahoma and may be an early bounding fault of the Southern Oklahoma aulacogen (Ardmore/Marietta basins). Horizontal displacement on the fault has been estimated to be up to 40 mi, with vertical displacement on the order of 10,000 ft. Samples collected from traverses across the Washita Valley fault have been analyzed. The traverses cross the fault at different stratigraphic levels from Proterozoic igneous basement, through the Cambrian-Ordovician Arbuckle Group, Ordovician Simpson and Viola Groups, to the Silurian-Devonian Hunton Group. Several types of fracture systems are documented that reflect mechanical stratigraphy, burial depth during deformation, and episodic movement on the fault. The fractures in the study area include open fracture systems, calcite-filled fractures, tension gashes, and fractures related to pressure solution. The samples were cut parallel to the strike of the fault, vertical-normal to the fault, and horizontal-normal to the fault. These cuts allow examination of the total fracture strain, characterization of the fractures, and statistical analysis of fracture density. From these data, fracture density is shown to decrease exponentially moving away from the primary fault zone. The increased understanding of fracture patterns and characteristics will assist future exploration and development programs involving carbonate reservoirs associated with strike-slip systems.

    We furnish an updated crayfish species list for the state of Oklahoma (United States of America), including an updated and illustrated dichotomous key. In addition, we include species accounts that summarize general characteristics, life coloration, similar species, distribution and habitat, life history, and syntopic species. Current and potential distributions were analyzed using ecological niche models to provide a critical resource for the identification of areas with conservation priorities and potential susceptibility to invasive species. Currently, Oklahoma harbors 30 species of crayfish, two of which were recently discovered. Eastern Oklahoma has the highest species diversity, as this area represents the western distribution extent for several species. The work herein provides baseline data for future work on crayfish biology and conservation in Oklahoma and surrounding states. PMID:26176099

GA has contended that it is not financially liable for the cleanup but stated it would be available to offer financial assistance if needed. Over the proposed 10-year cleanup schedule, GA said SFC can finance the decommissioning by drawing on SFC's estimated $70-million in revenue from a fee-for-contract agreement in its recently formed joint-venture with AlliedSignal Inc., called ConverDyn.

  18. Oklahoma's recent earthquakes and saltwater disposal.

    Walsh, F Rall; Zoback, Mark D

    2015-06-01

    Over the past 5 years, parts of Oklahoma have experienced marked increases in the number of small- to moderate-sized earthquakes. In three study areas that encompass the vast majority of the recent seismicity, we show that the increases in seismicity follow 5- to 10-fold increases in the rates of saltwater disposal. Adjacent areas where there has been relatively little saltwater disposal have had comparatively few recent earthquakes. In the areas of seismic activity, the saltwater disposal principally comes from "produced" water, saline pore water that is coproduced with oil and then injected into deeper sedimentary formations. These formations appear to be in hydraulic communication with potentially active faults in crystalline basement, where nearly all the earthquakes are occurring. Although most of the recent earthquakes have posed little danger to the public, the possibility of triggering damaging earthquakes on potentially active basement faults cannot be discounted.

    The Alfred P. Murrah Federal Building in Oklahoma City was partially destroyed by a terrorist bomb on April 19, 1995. Injuries were sustained by 759 people, 168 of whom died. Fatalities occurred primarily among victims in the collapse zone of the federal building. Only 83 survivors required hospitalization. Twenty-two surviving victims sustained multiple fractures. Most victims arrived at local emergency departments by private vehicle within 2 hours. More severely injured survivors were transported by ambulance. The closer receiving hospitals used emergency department facilities and minor treatment areas. Few survivors were extricated from the bombing site more than 3 hours after the detonation. Mass casualty plans must provide for improved communications, diversion and retriage from facilities nearest the disaster site, and effective coordination of community and hospital resources.

    These MISR images of Oklahoma and north Texas were acquired on March 12, 2000 during Terra orbit 1243. The three images on the left, from top to bottom, are from the 70-degree forward viewing camera, the vertical-viewing (nadir) camera, and the 70-degree aftward viewing camera. The higher brightness, bluer tinge, and reduced contrast of the oblique views result primarily from scattering of sunlight in the Earth's atmosphere, though some color and brightness variations are also due to differences in surface reflection at the different angles. The longer slant path through the atmosphere at the oblique angles also accentuates the appearance of thin, high-altitude cirrus clouds.

    On the right, two areas from the nadir camera image are shown in more detail, along with notations highlighting major geographic features. The south bank of the Red River marks the boundary between Texas and Oklahoma. Traversing brush-covered and grassy plains, rolling hills, and prairies, the Red River and the Canadian River are important resources for farming, ranching, public drinking water, hydroelectric power, and recreation. Both originate in New Mexico and flow eastward, their waters eventually discharging into the Mississippi River.

    A smoke plume to the north of the Ouachita Mountains and east of Lake Eufaula is visible in the detailed nadir imagery. The plume is also very obvious at the 70-degree forward view angle, to the right of center and about one-fourth of the way down from the top of the image.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

    This report documents a major storm which occurred August 27-28, 1977, in southwest Oklahoma near the communities of Cache and Faxon, OK. Blue Beaver Creek and West Cache Creek and their tributaries experienced extensive flooding that caused an estimated $1 million in damages. Reported rainfall amounts of 8 to 12 inches in 6 hours indicate the storm had a frequency in excess of the 100-year rainfall. Peak discharges on Blue Beaver Creek near Cache and West Cache Creek near Faxon were 13,500 cubic feet per second and 45,700 cubic feet per second respectively. The estimated flood frequency was in excess of 100 years on Blue Beaver Creek and in excess of 50 years on West Cache Creek. Unit runoff on small basins were in excess of 2000 cubic feet per second per square mile. Surveyed highwater marks were used to map the flooded area. (USGS)

  4. Feasibility study of heavy oil recovery in the Midcontinent region (Kansas, Missouri, Oklahoma)

    SciTech Connect

    Olsen, D.K.; Johnson, W.I.

    1993-08-01

    This report is one of a series of publications assessing the feasibility/constraints of increasing domestic heavy oil production. Each report covers a select area of the United States. The Midcontinent (Kansas, Nssouri, Oklahoma) has produced significant oil, but contrary to early reports, the area does not contain the huge volumes of heavy oil that, along with the development of steam and in situ combustion as oil production technologies, sparked the area`s oil boom of the 1960s. Recovery of this heavy oil has proven economically unfeasible for most operators due to the geology of the formations rather than the technology applied to recover the oil. The geology of the southern Midcontinent, as well as results of field projects using thermal enhanced oil recovery (TEOR) methods to produce the heavy oil, was examined based on analysis of data from secondary sources. Analysis of the performance of these projects showed that the technology recovered additional heavy oil above what was produced from primary production from the consolidated, compartmentalized, fluvial dominated deltaic sandstone formations in the Cherokee and Forest City basins. The only projects producing significant economic and environmentally acceptable heavy oil in the Midcontinent are in higher permeability, unconsolidated or friable, thick sands such as those found in south-central Oklahoma. There are domestic heavy oil reservoirs in other sedimentary basins that are in younger formations, are less consolidated, have higher permeability and can be economically produced with current TEOR technology. Heavy oil production from the carbonates of central and wester Kansas has not been adequately tested, but oil production is anticipated to remain low. Significant expansion of Midcontinent heavy oil production is not anticipated because the economics of oil production and processing are not favorable.

  5. Subsidence and thermal history of Southern Oklahoma aulacogen: implications for petroleum exploration

    SciTech Connect

    Feinstein, S.

    1981-12-01

    Reconstructed subsidence curves and the thermal history of the Southern Oklahoma aulacogen support the concept of thermally controlled isostatic subsidence for the formation of the basin and indicate the significance of this concept for petroleum exploration. Two mechanisms - initial elastic flexure, followed by detachment and differential subsidence of the aulacogen - are inferred from the subsidence curves. Two methods have been used for reconstruction of the thermal history. A tectonophysics model in combination with a history of basin evolution demonstrates that geothermal gradient and depth-of-burial were dynamic variables during the subsidence stage; maximum paleotemperatures were attained during Sylvan (Late Ordovician) time near the close of subsidence; and most of the Arbuckle Group had been subjected to the temperature conditions of oil formation (the oil liquid window) prior to the possible phase of fluid migration in Sylvan time. The second method, involving reconstruction of the geothermal history on the basis of geothermometry (palynomorph carbonization), suggests: (1) paleotemperatures exerted a significant effect on the level of organic metamorphism in the sedimentary rocks; (2) the geothermal gradient varied during the subsidence stage; (3) paleotemperatures were higher than those predicted by the theoretical model and support the hypothesis of formation of the basin by thermally controlled subsidence, and the application of this concept for petroleum exploration.

    Platt National Park, located in southern Oklahoma, containing 842 acres, was established by Acts of Congress in 1902, 1904, and 1906. The reason for the setting aside of this area was the presence in the area of some 30 'mineral' springs, the water from which contains sulphur, bromide, salt, and other minerals, which are believed to possess medicinal qualities. For many generations the sulphur springs of the Chickasaw Nation had been known for their reputed healing qualities. It had long been the custom for families to come from considerable distances on horseback and in wagons and camp near the springs, in order to drink the water. In course of time a primitive town, known as Sulphur Springs, grew up near a group of springs known since as Pavilion Springs at the mouth of Sulphur Creek, now known as Travertine Creek. This town was still in existence at the time of my first visit to the locality in July, 1901. At this time, in company with Joseph A. Taff, of the United States Geological Survey, I spent a week riding over the country making a preliminary survey looking toward the setting aside of the area for a National Park. After the establishment of the National Park, the old town of Sulphur Springs was abandoned, and when the present boundaries of the park had been established the present town of Sulphur, now county seat of Murray County, grew up. In July 1906, on request of Superintendent Joseph F. Swords, I visited the park and made an examination of the various springs and submitted a report, dated August 15, 1906, to Secretary of the Interior E.A. Hitchcock. Copies of this report are on file in the Regional Office and at Platt National Park. In this report I set forth the approximate amount of flow of the various springs, the character of the water in each, and the conditions of the springs as of that date. I also made certain recommendations regarding proposed improvements of each spring. In this report I say: 'In the town of Sulphur, four wells have been drilled to a depth of between 450 and 500 feet in which artesian water has been secured. These wells are said to flow 200,000 gallons each per day.' I also say: 'From a study of the log of one of these wells, it appears that the artesian water is derived from the upper part of the Simpson sandstone. It is very probable that the water of the springs is derived from the same source.' This early was recognized the relation between the water from the mineral springs and that from the artesian wells. As the years have passed, other wells have been drilled in the town of Sulphur, chiefly to supply water for mineral baths and for swimming pools, so that to date more than 30 wells have been drilled. The exact number is not known. The custom has usually been to turn the wells loose and permit them to flow at full capacity, although some of the wells have been 'valved in' and the flow reduced. An estimate furnished me by the Secretary of the Chamber of Commerce in 1937, referred to later in this report, indicated that at that time 16 wells were flowing approximately 28,800,000 gallons of water per day, practically all of which ran to waste. For many years geologists in Oklahoma and elsewhere have watched this unrestricted waste of water from the artesian wells at Sulphur with growing concern. Remembering the history of other artesian basins throughout the world, these geologists believed that in all probability it was only a question of time until the water in the Sulphur artesian basin would begin to fail. On two different occasions the State Geologist of Oklahoma, bearing these conditions in mind, has prepared and had introduced into the State Legislature a bill which, if enacted into law, would have regulated the flow of water in artesian wells throughout the State. Both bills died in committee. Partly on account of the drought of the past three years, the matter has been brought to a head. In September 1938, Buffalo and Antelope Springs at the hea

  8. Selected water-level records for Oklahoma, 1976-1978

    USGS Publications Warehouse

    Goemaat, Robert L.; Spiser, Dannie E.

    1979-01-01

    A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for use in basic research. Water-level data in table 1 are from wells that are measured annually, prior to the irrigation season to achieve the most natural representation of the static water level. Water level measurements listed in the column under 1976 may have been made during December 1975 or January, February, March, April, or May 1976. Measurements listed in the column 1977 may have been made during December 1976 or January, February, March, or April 1977. Figure 1 shows the counties and number of wells therein, where data were obtained for this report. Records of water levels in Oklahoma are collected through a cooperative program by the U.S. Geological Survey and the Oklahoma Water Resources Board. The records are tabulated and published by the U.S. Geological Survey on an annual basis. The stratigraphic nomenclature and age determinations used in this report are those accepted by the Oklahoma Geological Survey and do not necessarily agree with those at the U.S. Geological Survey except for the Cheyenne Sandstone which is considered to be Purgatoire Sandstone by the Oklahoma Geological Survey (Robert O. Fay, Personal Communication, August 9, 1979).

  9. Computer stereograms of Oklahoma subsurface geology

    SciTech Connect

    Todd, H.W.

    1987-08-01

    Three-dimensional stereoscopic illustrations have not been a standard part of the subsurface geologist's tool kit. Now, the immense complexity of stereograms can be resolved by inexpensive software on a personal computer, with which the subsurface geologist can gain an entirely new viewpoint. These new illustrations yield new patterns, new relationships, and prospective anomalies. The illustrations are particularly helpful in areas of complex structural geology. This study presents a regional sampling of this new mode of geologic illustration; Oklahoma was chosen because of its wide variety of structural styles, the prolific reserves associated with those structures, and the abundance of geologic data. A statewide data base of 2806 structural elevations on the base of the Pennsylvanian System was digitized from scout-ticket tops. In addition, three detailed data bases of local structures were digitized, using all the available structural control plus interpreted points to aid the programming. Contour maps and block diagrams were constructed with readily available, inexpensive software, using kriging algorithms. Stereo pairs were created by rotating the blocks 4/sup 0/ within the computer program. The pairs were positioned 2.5 in. apart to match an average viewer's interpupillary distance. The three-dimensional blocks may be viewed with a stereoscope or with naked eyes focused on a distant point.

    Studies of LANDSAT and Skylab-EREP data have defined both the advantages and limitations of space platforms as a new 'tool' in mineral exploration. One LANDSAT investigation in the Anadarko Basin of Oklahoma has demonstrated a correlation between several types of anomalies recognized in the imagery and the locations of known oil and gas fields. In addition to supporting several LANDSAT follow-on investigations in petroleum exploration, NASA has approved a broad in-house study at Goddard Space Flight Center designed to verify the general applicability of the initial Anadarko Basin results. Using both conventional photogeologic methods and special computer processing, imagery taken over oil-producing areas is being subjected to detailed analysis in search of definitive recognition criteria.

  10. Oklahoma geology, the challenge in a changing environment

    Miller, G.B. ); Tillman, B.L. )

    1993-02-01

    A diversity of geology and programs exists in Oklahoma which requires the SCS geologist to use a wide range of experience in order to contribute to the many existing programs. The US Soil Conservation Service geologist work force consists of Bob L. Tillman, Sedimentation Geologist, Chickasha, and Glen B. Miller, Engineering Geologist, Stillwater, Oklahoma. Their poster display illustrates channel erosion commonly encountered during planning investigations within Oklahoma. Channel erosion consists of the removal of soil and rock by a concentrated flow of water. It includes, but is not limited to, ephemeral gully erosion, streambank erosion, roadside erosion, and flood-plain scour. All contribute sediment to floodwater retarding structures and are important considerations in watershed planning. Each of these types of channel erosion are displayed and discussed on the poster display.

    The Ogallala aquifer, that part of the High Plains aquifer in Oklahoma, is part of a regional aquifer system that underlies parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. In 1978 the US Geological Survey began a 5- year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop a capability for predicting aquifer response to various ground-water-management alternatives (Weeks, 1978). -from Author

  14. Characteristics of successful aviation leaders of Oklahoma

    NASA Astrophysics Data System (ADS)

    Kutz, Mary N. Hill

    Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal responsibility. The most frequently identified curriculum need across all aviation disciplines was that of communication skills.

  15. Oklahoma blast forces unsettling design questions

    SciTech Connect

    1995-05-01

    The bomb that brought down a government building in Oklahoma City killed hundreds of people after it was detonated near the building`s key supports. The blast has reopened a long-simmering debate on safety by design. Structurally, it`s not practical to designing bomb-proof buildings. But it is possible to engineer a structure to deform rather than go through immediate progressive collapse. Delaying collapse gives occupants extra time to evacuate. And that could mean the difference between life and death. The construction material of choice really {open_quotes}depends on the height of the building and the lateral load resisting system,{close_quotes} says Charles H. Thornton of Thornton-Tomasetti/Engineers, New York City. But whether in steel or reinforced concrete, moment-resisting frames, which are inherently redundant, give horizontal components the ability to take reversals of stress common in explosions, he says. Simple frames do not. {open_quotes}They go down like a house of cards,{close_quotes} says Thornton. In reinforced concrete moment frames, beam reinforcing steel is continuous. In simple reinforced concrete frames, beam rebar only penetrates the column for a determined number of inches based on the length of the span. And it is absent from the mid-span of the beam. In a blast from below, the beam, its top usually in compression and bottom in tension, deflects up, throwing the beam top into tension. With no rebar, it loses structural integrity, and falls apart. With rebar, it has a chance of surviving. If a building is not designed for blasts, a steel frame might be better under a reasonably small bomb because steel has equal capacity in tension and compression, and concrete has capacity only in compression, says Thornton.

    SciTech Connect

    1995-02-09

    The Oklahoma Refining Company site, near the town of Cyril, Caddo County, Oklahoma, is approximately 160 acres. Contaminants associated with the site include volatile organic compounds, semi-volatile compounds, heavy metals, polycyclic aromatic hydrocarbons (PAHs), and petroleum hydrocarbons. Heavy metals and PAHs are the primary contaminants at levels of health concern. During refinery operations, ambient air was likely to have been and could be a significant exposure pathway for on-site workers and off-site residents. Residents swimming in Gladys Creek downstream of the ORC site during refinery operations were likely to have been exposed to contaminants in surface water and sediment. The Agency for Toxic Substances and Disease Registry (ATSDR) has concluded that the Oklahoma Refining Company site was a public health hazard during its past operation based on probable exposure during the release of wastes from the oil refinery process.

  13. Soil Moisture-Based Drought Monitoring in Oklahoma

    NASA Astrophysics Data System (ADS)

    Ochsner, T.; Scott, B. L.; Illston, B. G.

    2012-12-01

    Real-time drought monitoring is essential for early detection and adaptive management to mitigate the negative impacts of drought on communities and ecosystems in drought-prone locations like Oklahoma where the 2011 drought cost the state's economy over $1.5 billion from agricultural losses alone. Drought monitoring has been hampered by a lack of data on one crucial drought indicator: plant available water. Agricultural losses and, by extension, the economic impacts of drought, are strongly linked to plant available water. Plant available water (PAW) is the amount of soil moisture currently in the profile which is available for plant uptake. We have recently developed and launched a novel drought monitoring system for Oklahoma based on real-time PAW monitoring at >100 locations via the Oklahoma Mesonet. To our knowledge, this is the world's first large-scale PAW monitoring system and offers unmatched potential for improving the use of soil moisture measurements in drought monitoring. The Oklahoma system may serve as a prototype for the development of soil moisture-based drought monitoring systems in other locations or at the national level. This presentation will describe the system and demonstrate some applications of the data for drought monitoring, prediction, and mitigation.

    1993-04-01

    To determine the extent of firearms as a cause of mortality, Oklahoma vital statistic records were analyzed. The annual mortality rate in Oklahoma between 1985 and 1989 was 20% higher than the U.S. rate. Firearms were the second leading cause of injury deaths; firearms were the leading cause of injury deaths among blacks and the leading cause of all deaths among blacks 15 to 29 years of age. Ninety-two percent of the firearm-related deaths were intentional; firearms accounted for 70% of suicides and 59% of homicides. The male death rate from firearms was 4.5 times the female death rate. Suicide rates were highest among white males 65 years and older; homicide rates peaked among black males 25 to 34 years of age. Residents of eastern Oklahoma had the highest rates. The magnitude and preventability of firearm-related deaths and injuries demand attention and collaboration from Oklahoma health care providers; public health, mental health, and education officials; and criminal justice professionals.

  11. Industrial unionism and the Oklahoma coal industry, 1870-1935

    SciTech Connect

    Sewall, S.L.

    1992-01-01

    This study traces the development of industrial unionism in Oklahoma's coal industry from the beginnings of the industry in 1870 to its decline in 1935. Chapter topics include the early years of the coal industry, life in the coal towns, and the series of strikes that occurred from 1894 to 1932. The study draws from both labor and management materials, but also from primary sources that reflect the role of both the state and federal governments during strikes. The study also utilizes the newspapers of the coal towns. They are a bountiful source on life in Oklahoma's coal towns. Study concludes that Oklahoma's coal towns were a perfect breeding ground for industrial unionism. Working in the most dangerous mines in the United States, the miners of Oklahoma turned to unionism in their efforts to improve working conditions and to secure a living wage. Above ground, the miners battled to break the company towns system. There the union achieved success in eliminating the company store and company housing, the two principal components of the company town system. At the same time, the miners created a union culture under which miners of all nationalities were welcome.

  3. Ecoregions and stream morphology in eastern Oklahoma

    NASA Astrophysics Data System (ADS)

    Splinter, Dale K.; Dauwalter, Daniel C.; Marston, Richard A.; Fisher, William L.

    2010-10-01

    Broad-scale variables (i.e., geology, topography, climate, land use, vegetation, and soils) influence channel morphology. How and to what extent the longitudinal pattern of channel morphology is influenced by broad-scale variables is important to fluvial geomorphologists and stream ecologists. In the last couple of decades, there has been an increase in the amount of interdisciplinary research between fluvial geomorphologists and stream ecologists. In a historical context, fluvial geomorphologists are more apt to use physiographic regions to distinguish broad-scale variables, while stream ecologists are more apt to use the concept of an ecosystem to address the broad-scale variables that influence stream habitat. For this reason, we designed a study using ecoregions, which uses physical and biological variables to understand how landscapes influence channel processes. Ecoregions are delineated by similarities in geology, climate, soils, land use, and potential natural vegetation. In the fluvial system, stream form and function are dictated by processes observed throughout the fluvial hierarchy. Recognizing that stream form and function should differ by ecoregion, a study was designed to evaluate how the characteristics of stream channels differed longitudinally among three ecoregions in eastern Oklahoma, USA: Boston Mountains, Ozark Highlands, and Ouachita Mountains. Channel morphology of 149 stream reaches was surveyed in 1st- through 4th-order streams, and effects of drainage area and ecoregion on channel morphology was evaluated using multiple regressions. Differences existed (? ? 0.05) among ecoregions for particle size, bankfull width, and width/depth ratio. No differences existed among ecoregions for gradient or sinuosity. Particle size was smallest in the Ozark Highlands and largest in the Ouachita Mountains. Bankfull width was larger in the Ozark Highlands than in the Boston Mountains and Ouachita Mountains in larger streams. Width/depth ratios of the Boston Mountains and Ozark Highlands were not statistically different. Significant differences existed, however, between the Boston Mountains and Ozark Highlands when compared individually to the Ouachita Mountains. We found that ecoregions afforded a good spatial structure that can help in understanding longitudinal trends in stream reach morphology surveyed at the reach scale. The hierarchy of the fluvial system begins within a broad, relatively homogenous setting that imparts control on processes that affect stream function. Ecoregions provide an adequate regional division to begin a large-scale geomorphic study of processes in stream channels.

  5. University of Oklahoma - High Energy Physics

    Skubic, Patrick L.

    2013-07-31

    The High Energy Physics program at the University of Oklahoma, Pat Skubic, Principal Investigator, is attempting to understand nature at the deepest level using the most advanced experimental and theoretical tools. The four experimental faculty, Brad Abbott, Phil Gutierrez, Pat Skubic, and Mike Strauss, together with post-doctoral associates and graduate students, are finishing their work as part of the D0 collaboration at Fermilab, and increasingly focusing their investigations at the Large Hadron Collidor (LHC) as part of the ATLAS Collaboration. Work at the LHC has become even more exciting with the recent discovery by ATLAS and the other collaboration, CMS, of the long-sought Higgs boson, which plays a key role in generating masses for the elementary constituents of matter. Work of the OUHEP group has been in the three areas of hardware, software, and analysis. Now that the Higgs boson has been discovered, completing the Standard Model of fundamental physics, new efforts will focus on finding hints of physics beyond the standard model, such as supersymmetry. The OUHEP theory group (Kim Milton, PI) also consists of four faculty members, Howie Baer, Chung Kao, Kim Milton, and Yun Wang, and associated students and postdocs. They are involved in understanding fundamental issues in formulating theories of the microworld, and in proposing models that carry us past the Standard Model, which is an incomplete description of nature. They therefore work in close concert with their experimental colleagues. One also can study fundamental physics by looking at the large scale structure of the universe; in particular the ``dark energy'' that seems to be causing the universe to expand at an accelerating rate, effectively makes up about 3/4 of the energy in the universe, and yet is totally unidentified. Dark energy and dark matter, which together account for nearly all of the energy in the universe, are an important probe of fundamental physics at the very shortest distances, or at the very highest energies. The outcomes of the group's combined experimental and theoretical research will be an improved understanding of nature, at the highest energies reachable, from which applications to technological innovation will surely result, as they always have from such studies in the past.

  6. Trilobites from Lower Mississippian starved basin facies of the southern United States

    1998-01-01

    A distinctive trilobite fauna occurs within condensed statigraphic sections of the Lower Mississippian (Tournaisian) Chappel Limestone of the Llano region of Texas, the Welden Limestone of Oklahoma, and the Chouteau Limestone of Union County, Illinois. The seven species comprising this fauna are interpreted to have inhabited sediment-starved basinal environments. The starved-basin facies existed in the south-central United States throughout the Tournaisian (Kinderhookian to Osagean). Two species from this fauna, Australosutura llanoensis, and Carbonocoryphe planucauda, are new. The remaining five species, Griffithidella doris (Hall), Griffithidella alternata (Girty), Carbonocoryphe depressa (Girty), Thigiffides roundyi (Girty), and Pudoproetus chappelensis (Hessler), are restricted to starved-basin facies.

  7. Comparative analysis of wind energy production in Oklahoma

    NASA Astrophysics Data System (ADS)

    Ermilova, Ekaterina Alexeevna

    Scope and method of study. In the last decades humanity has realized the necessity of developing alternative energy sources for its efficient economic development and simple survival in the future. During the last 30 years major improvements were made in renewable energy technologies and they started to become competitive with traditional energy sources (fossil fuels), especially with consideration of external costs. Among the renewable energy sources, wind energy is one of the cheapest and fastest growing nowadays. Oklahoma is a very promising site for wind energy development considering its excellent wind resources. Developing wind energy can allow not only electricity production for in-state consumption, but also exporting to other states. The development of wind energy could encourage economic growth with very few adverse impacts on the environment. However, traditional energy sources are still the cheapest and, thus, the introduction of the wind energy in Oklahoma should be critically analyzed from economic, ecological and social points of view. The goal of this study is to conduct analysis of wind energy electricity production in Oklahoma on the four main stages: (1) Investment Analysis from Private Perspective: Calculate present value net benefits for wind energy and traditional energy (natural gas), make sure that both of them are positive. (2) Investment Analysis from Social Perspective: Evaluate present value net private benefits (PVNPB) and present value net social benefit from both projects (PVNSB). (3) Government Subsidy Analysis: recognize the necessity of the subsidies and evaluate the amount of subsidies if any. (4) Investment Analysis from a Geographic Perspective: determine economic feasibility of wind power generation for 77 Oklahoma counties. Findings and conclusions. The final output of the study is the recommendations concerning wind energy development in Oklahoma with consideration of economic efficiency, ecological and social impacts. Study not only analyze possibilities for wind energy development in the state, but make recommendations on the county by county basis with consideration of wind power density, land cost, property tax and infrastructure development in each county.

    1972-01-01

    The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies; (2) facilitate the prediction of trends in water levels that will indicate likely changes in storage; (3) aid in the prediction of the base flow of streams; (4) provide information for use in basic research; (5) provide long-time continuous records of fluctuations of water levels in representative wells; and (6) serve as a framework to which other types of hydrologic data my be related. Prior to 1956, measurements of water levels in observation wells in Oklahoma were included in water-supply papers published annually by the U.S. Geological Survey. Beginning with the 1956 calendar year, however, Geological Survey water-level reports will contain only records of a selected network of observation wells, and will be published at 5-year intervals. The first of this series, for the 1956-59 period was published in 1962. In addition to the water-supply papers, the U.S. Geological Survey, cooperation with the Oklahoma Water Resources Board, has published the following informal reports on water levels in Oklahoma. Ground-water levels in observations wells in Oklahoma, 1956-60 Ground-water levels in observations wells in Oklahoma, 1961-62 Ground-water levels in observations wells in Oklahoma, 1963-64 Ground-water levels in observations wells in Oklahoma, 1965-66 Ground-water levels in observations wells in Oklahoma, 1967-68 Records of water-level measurements in wells in the Oklahoma Panhandle, 1966-70 Records of water-level measurements in wells in the Oklahoma Panhandle, 1971-72 The basic observation-well network in Oklahoma during the period 1969-70 included the following counties: Alfalfa, Beaver, Beckham, Caddo, Cimarron, Cleveland, Garfield, Garvin, Grady, Greer, Harmon, Jackson, Kingfisher, LeFlore, Major, Muskogee, Oklahoma, Payne, Pontotoc, Rogers, Sequoyah, Texas, Tillman, Wagoner, Washita, and Woodward. Table 2 includes the basic observation-well network and other wells measured by the U.S. Geological Survey. The data in this report were compiled and prepared for publication under the cooperative agreement for ground-water investigations in Oklahoma between the Oklahoma Water Resources Board, the U.S. Army Corps of Engineers, the Oklahoma Geological Survey, and the U.S. Geological Survey.

    The West Carney Field in Lincoln County, Oklahoma is one of few newly discovered oil fields in Oklahoma. Although profitable, the field exhibits several unusual characteristics. These include decreasing water-oil ratios, decreasing gas-oil ratios, decreasing bottomhole pressures during shut-ins in some wells, and transient behavior for water production in many wells. This report explains the unusual characteristics of West Carney Field based on detailed geological and engineering analyses. We propose a geological history that explains the presence of mobile water and oil in the reservoir. The combination of matrix and fractures in the reservoir explains the reservoir's flow behavior. We confirm our hypothesis by matching observed performance with a simulated model and develop procedures for correlating core data to log data so that the analysis can be extended to other, similar fields where the core coverage may be limited.

    Hunton formation in Oklahoma has been the subject of attention for the last ten years. The new interest started with the drilling of the West Carney field in 1995 in Lincoln County. Subsequently, many other operators have expanded the search for oil and gas in Hunton formation in other parts of Oklahoma. These fields exhibit many unique production characteristics, including: (1) decreasing water-oil or water-gas ratio over time; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods by which we can optimize the production from fields with similar characteristics.

    Pollen from members of the Cupressaceae are major aeroallergens in many parts of the world. In the south central and southwest United States, Juniperus pollen is the most important member of this family with J. ashei (JA) responsible for severe winter allergy symptoms in Texas and Oklahoma. In New Mexico, pollen from J. monosperma (JM) and other Juniperus species are important contributors to spring allergies, while J. pinchotii (JP) pollinates in the fall affecting sensitive individuals in west Texas, southwest Oklahoma and eastern New Mexico. Throughout this region, JA, JM, and JP occur in dense woodland populations. Generally monitoring for airborne allergens is conducted in urban areas, although the source for tree pollen may be forested areas distant from the sampling sites. Improved pollen forecasts require a better understanding of pollen production at the source. The current study was undertaken to examine the aerobiology of several Juniperus species at their source areas for the development of new pollen forecasting initiatives.

    Dendroica cerulea (Cerulean Warbler) is a migrant songbird that has declined rangewide in recent decades. We surveyed 150 sites in 2006–2007 to determine if this species still occupied its former breeding range in Oklahoma. We located Cerulean Warblers at 5 sites and confirmed breeding on north slopes of two heavily forested ridges in the Ouachita Mountains. We did not encounter Cerulean Warblers in any bottomland hardwoods, despite the former widespread distribution and abundance of the species in such habitats. While habitat loss and degradation may limit occurrence of Cerulean Warbler in some areas, the pattern of decline for this species at the edge of its range in Oklahoma is also consistent with abandonment of peripheral range as the range-wide population declines.

    Subspace detection is a powerful and adaptive tool for continuously detecting low signal to noise seismic signals. Subspace detectors improve upon simple cross-correlation/matched filtering techniques by moving beyond the use of a single waveform template to the use of multiple orthogonal waveform templates that effectively span the signals from all previously identified events within a data set. Subspace detectors are particularly useful in event scenarios where a spatially limited source distribution produces earthquakes with highly similar waveforms. In this context, the methodology has been successfully deployed to identify low-frequency earthquakes within non-volcanic tremor, to characterize earthquakes swarms above magma bodies, and for detailed characterization of aftershock sequences. Here we apply a subspace detection methodology to characterize recent earthquakes clusters in Oklahoma. Since 2009, the state has experienced an unprecedented increase in seismicity, which has been attributed by others to recent expansion in deep wastewater injection well activity. Within the last few years, 99% of increased Oklahoma earthquake activity has occurred within 15 km of a Class II injection well. We analyze areas of dense seismic activity in central Oklahoma and construct more complete catalogues for analysis. For a typical cluster, we are able to achieve catalog completeness to near or below magnitude 1 and to continuously document seismic activity for periods of 6 months or more. Our catalog can more completely characterize these clusters in time and space with event numbers, magnitudes, b-values, energy, locations, etc. This detailed examination of swarm events should lead to a better understanding of time varying earthquake processes and hazards in the state of Oklahoma.

    1956-01-01

    Uranium-bearing carbonaceous nodules have been found along the north flank of the Wichita uplift in southwestern Oklahoma. The carbonaceous nodules are black, hard, and predominantly nodular shaped. One specimen, by analyses, was found to contain approximately 42 percent carbon and 3 percent hydrogen. The uranium, vanadium, cobalt, arsenic, nickel, lead and iron contents each range between 1 and 10 percent. It is concluded that the carbonaceous nodules are epigenetic and that the organic and inorganic constituents were derived from, mobile soluttons.

    Rocks that make up the Arbuckle-Simpson aquifer crop out over ~500 mi2 in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000-9,000 ft thick. The rocks were subjected to intensive folding and faulting associated with major uplift of the area during Early to Late Pennsylvanian time.

    1985-01-01

    American coots (Fulica americana) were studied on large reservoirs in north-central Oklahoma in 1979-1982 to determine chronologies of migrations by age- and sex class. Coots began migrating into Oklahoma in mid-September, numbers peaked in early to mid-October, and few birds were seen after 1 November. Some late migrants appeared in mid-December. In spring, coots began migrating in late February, numbers peaked in mid-April, and the last birds were seen in mid-May. Generally, adult and juvenile males and juvenile female coots migrated simultaneously in autumn, but adult females completed migration by 1 November. A few juveniles and adult males migrated in December. Adult coots preceded yearlings in spring. Despite annual and between-lake differences in chronology of autumn migration, most coots migrated before waterfowl hunting season in Oklahoma. Coot hunting seasons in mid-latitude states should commence before the general waterfowl season where management goals are to increase hunter interest and the harvest of birds.

    Background This study describes overall and site specific cancer incidence among AI/ANs compared to whites in Oklahoma and differences in cancer staging. Methods Age-adjusted incidence rates obtained from the Oklahoma Central Cancer Registry are presented for all cancer sites combined and for the most common cancer sites among AI/ANs with comparisons to whites. Percentages of late stage cancers for breast, colorectal, and melanoma cancers are also presented. Results AI/ANs had a significantly higher overall cancer incidence rate compared to whites (629.8/100,000 vs. 503.3/100,000), with a rate ratio of 1.25 (95% CI: 1.22, 1.28). There was a significant disparity in the percentage of late stage melanoma cancers between 2005 and 2009, with 14.0% late stage melanoma for whites and 20.0% for AI/ANs (p-value: 0.03). Conclusions Overall, there were cancer disparities between AI/ANs and whites in Oklahoma. Incidence rates were higher among AI/ANs for all cancers and many site specific cancers. PMID:24800463

  2. Paleokarstic phenomena of the Lower Ordovician red bed sequences of the Arbuckle group, southern Oklahoma

    1991-06-01

    Oil and gas production has been reported recently from paleokarstic Arbuckle reservoirs in the Ardmore and Arkoma basin. The West Spring Creek and the Kindblade formations apparently exhibit karstic features. The most extensive surface exposure of these formations is on the southern flank of the Arbuckle anticline along Interstate 35 north of Ardmore, Oklahoma. The lithology is predominantly limestone, ranging from argillaceous mudstone to oolitic and/or bioclastic grainstones. However, minor amounts of sandstone were also observed.These lithologies are characteristic of various peritidal facies. Of particular interest in this outcrop are three distinct red bed zones. Although the zones are part of the repetitive shallowing-upward cycles that characterize the West Spring Creek Formation, ample evidence suggests the red beds represent subaerial exposure surfaces where karstification took place. Many of the thin bedded, rubbly mudstones and wackestones actually represent varieties of breccia commonly associated with karst. Collapse and crackle breccia are most commonly observed. Small solution channels and other vugs are usually completely occluded by calcite cement. However, solution cavities or vugs with diameters larger than 10 cm (3.9 in.) are lined with drusy calcite. Hematite-impregnated sediment occurs as thinly laminated infilling of solution vugs and cavities and also acts as a cementing agent of collapse breccias. Preliminary evidence suggests that karstification processes were active during Arbuckle deposition.

  3. Geodynamic basin classification

    SciTech Connect

    Klein, G.

    1987-05-01

    Four criteria (continental margin type, basin position within a plate, crustal type, geodynamic models and processes of basin formation) are used to classify sedimentary basins. Within plate interiors, cratonic margin basins and interior cratonic basins are distinguished by position on a tectonic plate. In passive margins, rift basins, aulacogens, and flexure basins are distinguished by orientation with respect to margins (rifts parallel and aulacogens normal to margins) and geodynamic process (rifts and aulacogens form by stretching, flexure basins by elastic or viscoelastic flexure). Basins associated with active continental margins are distinguished by position with respect to margin, crustal type, and stress regimen. Trench-slope basins involve compressional-extensional regimens, whereas trench basins, forearc basins and retroarc basins form in compressional regimes (retroarc basins on continental crust; forearc and trench basins occupy different positions on margin boundaries). Extensional intra-arc basins form on continental crust whereas backarc basins form by rifting oceanic crust and rapid thermal subsidence. Both pull-apart and transform basins form in transform margins by rifting and thermal subsidence with different translational stress regimens. In collision margins, foreland basins occur within continental plates, and superposed (or collage) basins occur along suture zones. Polyhistory basins include successor basins involving changing tectonic styles, and resurgent basins involving repeated tectonic styles. Many mapped basins show polyhistory. Thus the cratonic Illinois basin evolved through stages of a rift basin, followed by thermal subsidence akin to passive margins, followed by viscoelastic basin formation akin to a foreland basin.

  4. Effects of biodegradation upon porphyrin biomarkers in Upper Mississippian tar sands and related oils, southern Oklahoma

    Organic molecules present in oils which show a structural relationship to their biological precursors are referred to as biomarkers. These compounds are becoming widely used in oil exploration for making oil-oil, oil-source rock correlations and undertaking maturation and migration studies in basin analysis. Treibs first discovered the presence of porphyrins in oils, shales, and coals over 50 years ago. Porphyrins are predominantly derived from chlorophyll precursors present in plants and bacteria. Studies of changes in porphyrin distributions with increasing maturation due to the effects of increased time of burial and temperature have been performed. However, little is known as to how their distributions change with migration, biodegradation, or water washing of oils. In the present study, 16 tar sand samples were extracted from drill core at depths ranging from 16 to 256 ft obtained from a tar sand quarry in the Ardmore basin, Carter County, Oklahoma. Surrounding oil samples and possible source rocks have also been analyzed to determine the source of the oil in the tar sands. The effects of biodegradation on the porphyrin distributions can be discerned from the effects of migration and maturation by comparing other biomarker distributions within the sands, related oils, and suspected source rocks. Biodegradation of the tar sand samples can be observed within the alkane and other biomarker distributions. The relative effects of biodegradation on biomarkers such as alkanes, steranes, and terpanes have been well documented. By using this information, it is possible to determine the extent of biodegradation or water washing necessary to alter the porphyrin distributions.

  5. Proposed shallow drilling at the interface between the southern Oklahoma aulacogen and Ouachita fold belt, Arbuckle Mountains region, Oklahoma

    Two major tectonic elements in southern North America are the southern Oklahoma aulacogen and the Ouachita foldbelt. The Aulacogen is characterized by basement-cored high-angle fault blocks along which movement occurred throughout much of Paleozoic time. It is one of the most intensely deformed areas in the stable interior platform of the craton. The fold belt, in contrast, consists primarily of thin-skinned compressional structures that formed in Late Paleozoic time. These two prominent tectonic features strike at a high angle to one another and are juxtaposed in southeast Oklahoma where the contact is buried shallowly beneath Cretaceous rocks of the Gulf Coastal Plain. A drilling program comprised of a series of shallow holes drilled across the contact zone will establish the structural and stratigraphic relationships at this important tectonic interface. The results obtained should be critical in elucidating the effect that the transverse aulacogen structures had on the development of the Ouachita frontal zone. Proposed drilling sites are in northern Bryan and Choctaw counties, Oklahoma, along the Tishomingo--Belton anticlines southeast of the basement-cored eastern Arbuckle Mountains. Crystalline rocks in this region are massive middle Proterozoic granitoid rocks overlain by Cretaceous sedimentary rocks. Farther southeast, rocks in the frontal zone consist mainly of Late Paleozoic flysch-type sedimentary rocks. Depths to Paleozoic and older rocks beneath the coastal plain deposits are about 300--500 meters so that targeted structures can easily be reached.

    The Parana basin is a large intracratonic basin in South America, developed entirely on continental crust and filled with sedimentary and volcanic rocks ranging in age from Silurian to Cretaceous. It occupies the southern portion of Brazil (1,100,000 km/sup 2/ or 425,000 mi/sup 2/) and the eastern half of Paraguay (100,000 km/sup 2/ or 39,000 mi/sup 2/); its extension into Argentina and Uruguay is known as the Chaco-Parana basin. Five major depositional sequences (Silurian, Devonian, Permo-Carboniferous, Triassic, Juro-Cretaceous) constitute the stratigraphic framework of the basin. The first four are predominantly siliciclastic in nature, and the fifth contains the most voluminous basaltic lava flows of the planet. Maximum thicknesses are in the order of 6000 m (19,646 ft). The sequences are separated by basin wide unconformities related in the Paleozoic to Andean orogenic events and in the Mesozoic to the continental breakup and sea floor spreading between South America and Africa. The structural framework of the Parana basin consists of a remarkable pattern of criss-crossing linear features (faults, fault zones, arches) clustered into three major groups (N45/sup 0/-65/sup 0/W, N50/sup 0/-70/sup 0/E, E-W). The northwest- and northeast-trending faults are long-lived tectonic elements inherited from the Precambrian basement whose recurrent activity throughout the Phanerozoic strongly influenced sedimentation, facies distribution, and development of structures in the basin. Thermomechanical analyses indicate three main phases of subsidence (Silurian-Devonian, late Carboniferous-Permian, Late Jurassic-Early Cretaceous) and low geothermal gradients until the beginning of the Late Jurassic Permian oil-prone source rocks attained maturation due to extra heat originated from Juro-Cretaceous igneous intrusions. The third phase of subsidence also coincided with strong tectonic reactivation and creation of a third structural trend (east-west).

  7. Groundwater quality and water-well characteristics in the Kickapoo Tribe of Oklahoma Jurisdictional Area, central Oklahoma, 1948--2011

    In 2012, the U.S. Geological Survey, in cooperation with the Kickapoo Tribe of Oklahoma, compiled historical groundwater-quality data collected from 1948 to 2011 and water-well completion information in parts of Lincoln, Oklahoma, and Pottawatomie Counties in central Oklahoma to support the development of a comprehensive water-management plan for the Tribes jurisdictional area. In this study, water-quality data from 155 water wells, collected from 1948 to 2011, were retrieved from the U.S. Geological Survey National Water Information System database; these data include measurements of pH, specific conductance, and hardness and concentrations of the major ions, trace elements, and radionuclides that have Maximum Contaminant Levels or Secondary Maximum Contaminant Levels in public drinking-water supplies. Information about well characteristics includes ranges of well yield and well depth of private water wells in the study area and was compiled from the Oklahoma Water Resources Board Multi-Purpose Well Completion Report database. This report also shows depth to water from land surface by using shaded 30-foot contours that were created by using a geographic information system and spatial layers of a 2009 potentiometric surface (groundwater elevation) and land-surface elevation. Wells in the study area produce water from the North Canadian River alluvial and terrace aquifers, the underlying Garber Sandstone and Wellington Formation that compose the GarberWellington aquifer, and the Chase, Council Grove, and Admire Groups. Water quality varies substantially between the alluvial and terrace aquifers and bedrock aquifers in the study area. Water from the alluvial aquifer has relatively high concentrations of dissolved solids and generally is used for livestock only, whereas water from the terrace aquifer has low concentrations of dissolved solids and is used extensively by households in the study area. Water from the bedrock aquifer also is used extensively by households but may have high concentrations of trace elements, including uranium, in some areas where groundwater pH is above 8.0. Well yields vary and are dependent on aquifer characteristics and well-completion practices. Well yields in the unconsolidated alluvial and terrace aquifers generally are higher than yields from bedrock aquifers but are limited by the thickness and extent of these river deposits. Well yields in the alluvium and terrace aquifers commonly range from 50 to 150 gallons per minute and may exceed 300 gallons per minute, whereas well yields in the bedrock aquifers commonly range from 25 to 50 gallons per minute in the western one-third of study area (Oklahoma County) and generally less than 25 gallons per minute in the eastern two-thirds of the study area (Lincoln and Pottawatomie Counties).

  8. Preliminary appraisal of the hydrology of the Rock Island area, Le Flore County, Oklahoma

    Marcher, M.V.

    1983-01-01

    Bed rock in the Rock Island area of northeastern Le Flore County in southeastern Oklahoma consists of shale, siltstone, and sandstone of the McAlester, Hartshorne, and Atoka Formations of Pennsylvanian age. The area is on the south flank of the Backbone anticline; the rocks dip to the south at 5o-45o. Alluvium along James Fork consists of sandy and clayey silt and may be as much as 30 feet thick. Water in bedrock is under artesian conditions. The depth to water in most wells is less than 20 feet below the surface; a few wells flow. Yields of most wells probably are less than 5 gallons per minute. Water from nine wells was a sodium carbonate or sodium mixed anion type; dissolved-solids concentrations ranged from 294 to 1,250 milligrams per liter. No relationship between variations in chemistry of ground water and well depth, geographic distribution, or geologic formation is apparent. James Fork has flow most of the time and discharge exceeds 25 cubic feet per second about one-half the time. The mean dissolved-solids concentration in James Fork water ranged from 224 milligrams per liter near Williams, Oklahoma, to 332 milligrams per liter near Hackett, Arkansas. Water in James Fork is a calcium magnesium sulfate type about 75 percent of the time. Maximum suspended sediment discharge was 2,720 tons per day. Silt-clay particles (diameters less than 0.062 millimeter) are the dominant sediment size. Potential hydrologic effects of surface mining for coal include: (1) Creation of additional water storage in surface-mine ponds, (2) changes in rock permeability and ground-water storage, (3) changes in runoff and streamflow characteristics, (4) changes in drainage patterns, and (5) changes in the chemical quality and sediment load of James Fork. Although mining may increase the quantities of sediment and dissolved minerals added to James Fork, detection of these increases would be difficult because the potentially mineable area is very small in proportion to the total area of the basin.

  17. Multidisciplinary Approach to Identify and Mitigate the Hazard from Induced Seismicity in Oklahoma

    NASA Astrophysics Data System (ADS)

    Holland, A. A.; Keller, G. R., Jr.; Darold, A. P.; Murray, K. E.; Holloway, S. D.

    2014-12-01

    Oklahoma has experienced a very significant increase in seismicity rates over the last 5 years with the greatest increase occurring in 2014. The observed rate increase indicates that the seismic hazard for at least some parts of Oklahoma has increased significantly. Many seismologists consider the large number of salt-water disposal wells operating in Oklahoma as the largest contributing factor to this increase. However, unlike many cases of seismicity induced by injection, the greatest increase is occurring over a very large area, about 15% of the state. There are more than 3,000 disposal wells currently operating within Oklahoma along with injection volumes greater than 2010 rates. These factors add many significant challenges to identifying potential cases of induced seismicity and understanding the contributing factors well enough to mitigate such occurrences. In response to a clear need for a better geotechnical understanding of what is occurring in Oklahoma, a multi-year multidisciplinary study some of the most active areas has begun at the University of Oklahoma. This study includes additional seismic monitoring, better geological and geophysical characterization of the subsurface, hydrological and reservoir modeling, and geomechanical studies to better understand the rise in seismicity rates. The Oklahoma Corporation Commission has added new rules regarding reporting and monitoring of salt-water disposal wells, and continue to work with the Oklahoma Geological Survey and other researchers.

It was concluded that the New Mexico portion of the Permian Basin has the greatest potential for future fuel production. During 1980, there were 646 oil well completions, and 168 dry holes were recorded in southeast New Mexico. The average total depths of new wells completed was 4,901 feet for oil wells, 8,987 feet for gas wells, and 6,250 feet for dry holes.

  20. Nitrogen and Phosphorus Loads in an Agricultural Watershed Affected by Poultry Litter Application and Wastewater Effluent, Northeastern Oklahoma and Northwestern Arkansas, 2002-2009

    The Eucha-Spavinaw Basin in Northeastern Oklahoma and Northwestern Arkansas is the source of water for Lake Eucha and Spavinaw Lake, which are part of the water supply for the city of Tulsa, Oklahoma. Lake Eucha and Spavinaw Lakes have experienced deteriorating water quality largely due to growth of algae, notably cyanobacteria, from the excess input of nutrients. As a result, the city of Tulsa has spent millions of dollars to eliminate taste and odor problems resulting from production of algal and bacterial byproducts. To evaluate changes in nutrient loading resulting from a reduction in land application of poultry litter, installation of best management practices, and reductions in the phosphorus concentrations in wastewater effluent, the U.S. Geological Survey investigated nitrogen and phosphorus concentrations from samples collected during baseflow and runoff and used regression models to estimate nitrogen and phosphorus loads, yields, and flow-weighted concentrations in two major tributaries to Lake Eucha, Spavinaw and Beaty Creeks, for the period 2002-2009. Estimated mean flow-weighted total unfiltered nitrogen and phosphorus concentrations in the basin were about 5 to 10 times greater than the 75th percentile of flow-weighted nutrient concentrations in other mostly undeveloped basins of the United States. Spavinaw and Beaty Creeks contributed an estimated mean annual total load of about 762,500 kilograms of nitrogen and 49,200 kilograms of phosphorus per year, 76 to 91 percent of which was transported to Lake Eucha by runoff. Thirty-four percent of the nitrogen load and 48 percent of the phosphorus load to Lake Eucha occurred during the year 2008 which was the wettest year on record for the Eucha-Spavinaw Basin. The results of this analysis indicate that although efforts were made to control nutrient loading, nutrient concentrations, especially phosphorus, were substantially augmented by non-point sources and that most loading occurs during runoff events. These results indicate that precipitation and streamflow will likely continue to have the largest affect on nutrient loading in the basin while non-point sources dominate nutrient contributions. Global climate change forecasts for this region indicate that the magnitude of annual precipitation and frequency and intensity of storm events will likely increase which indicate that total nutrient loading may increase with time. However, negative coefficients for independent variables representing time in the phosphorus load regression model for Spavinaw Creek suggest that when streamflow is factored out, flow-weighted concentrations in this basin may have decreased over the study period, possibly from reduction of either non-point or point sources of nutrients in the basin.

    Background American Indians in Oklahoma have higher rates of tobacco use (29.2%) than any other racial group in the state. The Oklahoma Tobacco Helpline provides free cessation services to all Oklahomans and implements strategies specifically aimed at increasing the utilization and effectiveness of cessation services for American Indians. Purpose To explore Helpline utilization patterns as well as outcomes, such as participant satisfaction and success in quitting, for American Indians. The utilization patterns and outcomes for American Indians were compared to that of the white population from July 1, 2010, to June 30, 2013, to determine whether the Helpline is equally effective among American Indians compared to whites. Methods Helpline utilization data from July 1, 2010, to June 30, 2013, were analyzed in the fall of 2013 to identify patterns and compare differences between American Indian and white Helpline registrants. Four- and 7-month follow-up survey data were used to compare outcomes related to satisfaction with services and quit rates. Results During the 3-year study period, 10.6% of registrants who enrolled in an intervention were American Indian (11,075) and 71.2% were white (74,493). At the 7-month follow-up survey, 31.7% of American Indians reported having used no tobacco in the past 30 days compared to 36.5% of whites, but the differences were not statistically significant between racial groups. Conclusions The Oklahoma Tobacco Helpline is equally effective for American Indian and white tobacco users who register for Helpline services. PMID:25528707

    In this unusually clear view, the Ouachita Mountains of southeastern Oklahoma are framed on the north by Lake Eufaula on the South Canadian River, and on the south by the Red River. Clouds formed by upslope winds border both the north and south sides of the synclines (in a syncline the rock layers dip toward the center of the structure). Toward the west, densely forested mountains give way to gently rolling, less rocky terrain and a drier climate. The mountains centered on Broken Bow, in the lower right corner of the scene, display abundant timber clearcuts that are being regenerated.

    The objectives of the observation-well program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate the future availability of ground-water supplies, and (3) to provide information for use in basic research. These selected records serve as a framework to which other types of hydrologic data may be related. The stratigraphic nomenclature and age determinations used in this report are those accepted by the Oklahoma Geological Survey and do not necessarily agree with those of the U.S. Geological Survey.

    Geochemical, petrographic, and rock-magnetic studies were undertaken to investigate possible sources for reported positive aeromagnetic anomalies over the Cement oil field, Oklahoma. Ferrimagnetic pyrrhotite (monoclinic, Fe7S8 ), intergrown with more-abundant, nonmagnetic pyrite (FeS2), is present in well-cutting, core, and quarry samples at Cement, and it is the only identified source of possible enhanced magnetization in rocks over the field. Magnetite, found only in well cuttings from Cement, is contamination from drilling. Magnetite was considered previously by others to be the source of magnetic anomalies at Cement.

    This report presents the work done so far on Hunton Formation in West Carney Field in Lincoln County, Oklahoma. West Carney Field produces oil and gas from the Hunton Formation. The field was developed starting in 1995. Some of the unique characteristics of the field include decreasing water oil and ratio over time, decreasing gas-oil ratio at the beginning of production, inability to calculate oil reserves in the field based on long data, and sustained oil rates over long periods of time.

    Black Fork Mountain Roadless Area covers about 21 sq mi in the Ouachita National Forest in Polk County, Arkansas and LeFlore County, Oklahoma. On the basis of a mineral survey the area has little promise for the occurrence of metallic mineral resources. Stone and sand and gravel suitable for construction purposes occur in the Jackfork Sandstone and the Stanley Shale which also occur outside the roadless area. Although the potential for gas and oil is unknown and no resource potential was identified, some investigators believe that there is a possibility for the occurrence of gas and oil in the roadless area.

    1994-08-01

    Geochemical and paleomagnetic results from Cambro-Ordovician Royer Dolomite in the Arbuckle Mountains, southern Oklahoma, suggest a connection between dolomite type and magnetizations. One dolomite type, which is most common in the vicinity of the Arbuckle Anticline, has a dull luminescence, low ?18O values, coeval to slightly lower 87Sr/86Sr ratios and contains an easterly Cambro-Ordovician magnetization in magnetite. To the southeast, closer to the Ouachita Mountain front, most of the Royer dolomite contains a southeasterly and shallow magnetization in magnetite that is interpreted to be Late Paleozoic in age. In contrast to the other dolomites, these dolomites contain abundant authigenic K-feldspar and pyrite, radiogenic 87Sr/86Sr ratios, and have a bright (red) luminescence, all of which are consistent with alteration by basinal fluids. At one site, a stromatolitic bioherm, dolomites similar to those at the Arbuckle Anticline are surrounded by the altered dolomites. The distribution of specimen directions at this site is streaked between a Cambro-Ordovician and Late Paleozoic direction. The results of this study suggest a connection, either direct (by causing precipitation) or indirect (by increasing permeabilities for another fluid), between a radiogenic fluid and a chemical magnetization in magnetite. The relatively unaltered dolomites at the stromatolitic bioherm site escaped the almost pervasive alteration and remagnetization caused by the basinal fluids close to the Ouachita Mountains, a potential source for the fluids.

    The Cambro-Ordovician Arbuckle Group in the Arbuckle Mountains, south-central Oklahoma, had a complex history of dolomitization that resulted in two different geometries of dolomite bodies: stratal dolomite, of stratigraphically consistent, widespread distribution, and non-stratal dolomite, of stratigraphically inconsistent, local occurrence. Stratal dolomite includes the Royer and Butterly units in the lower Arbuckle Group. Most stratal dolomite samples are coarsely crystalline and have {sup 87}Sr/{sup 86}Sr ratios similar to Late Cambrian limestone and coeval seawater. All stratal dolomite and Arbuckle limestone samples have low {Delta}{sup 18}O values. Nonstratal dolomite is present in two areas: the Tishomingo Anticline and the Arbuckle Anticline. In the Tishomingo Anticline area, massive bodies (> 10 km{sup 2}) of nonstratal dolomite are present in a paleokarst system of pre-Middle Ordovician age. The petrographic and isotopic characteristics suggest that the nonstratal dolomite probably resulted from dolomitization of recrystallized limestone by post-Early Ordovician seawater. In the Arbuckle Anticline area, nonstratal dolomite is present as small irregular bodies that are related to Pennsylvanian faults and are associated with the margins of stratal Butterly dolomite. The nonstratal dolomite, medium to coarsely crystalline and brightly luminescent, is characterized by high {sup 87}Sr/{sup 86}Sr ratios values, and Fe and Mn concentrations, relative to all Arbuckle carbonates. Such compositions suggest that this type of dolomite probably originated from fluids that were derived from the adjacent basin(s) during late Paleozoic time.

    Parameters of most equations used to predict runoff from an ungaged area are based on characteristics of the watershed and subject to the biases of a hydrologist. Digital multispectral scanner, MSS, data from ERTS was reduced with the aid of computer programs and a Dicomed display. Multivariate analyses of the MSS data indicate that discrimination between watersheds with different runoff capabilities is possible using ERTS data. Differences between two visible bands of MSS data can be used to more accurately evaluate the parameters than present subjective methods, thus reducing construction cost due to overdesign of flood detention structures.

    The fluvial system represents a nested hierarchy that reflects the relationship among different spatial and temporal scales. Within the hierarchy, larger scale variables influence the characteristics of the next lower nested scale. Ecoregions represent one of the largest scales in the fluvial hierarchy and are defined by recurring patterns of geology, climate, land use, soils, and potential natural vegetation. Watersheds, the next largest scale, are often nested into a single ecoregion and therefore have properties that are indicative of a given ecoregion. Differences in watershed morphology (relief, drainage density, circularity ratio, relief ratio, and ruggedness number) were evaluated among three ecoregions in eastern Oklahoma: Ozark Highlands, Boston Mountains, and Ouachita Mountains. These ecoregions were selected because of their high-quality stream resources and diverse aquatic communities and are of special management interest to the Oklahoma Department of Wildlife Conservation. One hundred thirty-four watersheds in first-through fourth-order streams were compared. Using a nonparametric, two-factor analysis of variance (?? = 0.05) we concluded that the relief, drainage density, relief ratio, and ruggedness number all changed among ecoregion and stream order, whereas circularity ratio only changed with stream order. Our study shows that ecoregions can be used as a broad-scale framework for watershed management. ?? 2011 by Association of American Geographers.

    The Southern Great Plains (SGP) of the United States is a region of dynamic weather and climate. In addition, the SGP region has demonstrated significant coupling between the land surface and atmospheric processes across varying spatial and temporal scales during the warm season. As such, mesocsale events including deep convection as well as regional drought and pluvial periods are impacted by land-atmosphere inter actions and gradients in the surface conditions. With the establishment of the Oklahoma Mesonet in 1994 and subsequent upgrades to the sensors deployed at the over 100 sites across the state, near real-time, collocated observations of soil and atmospheric variables have been collected, quality assured, and archived. At the same time additional observing systems and field campaigns have increased the breadth of the information gathered on soil, vegetation, and atmospheric processes across the SGP region. Such datasets have led (a) to numerous studies that have increased the understanding of how land-atmosphere interactions impact the local weather and climate of the SGP region and (b) new techniques to link in situ observations with remote sensing to provide improved understanding of surface-atmosphere exchange. Most recently, Oklahoma Mesonet soil and atmospheric observations have been combined with near real-time land surface conditions via MODIS remotely sensed data to improve estimates of evapotranspiration at local and regional scales, understand the dynamics of flash drought, and address the water budget of the region.

    The Arbuckle Group of southern Oklahoma displays the only complete exposure of the shallow-water carbonates that characterize the Lower Ordovician of interior North America. Trilobites have been described from some parts of this sequence and sporadic occurrences of other invertebrates are known, but much of the sequence is sparingly fossiliferous. As a consequence, these magnificent exposures have not contributed notably to continuing efforts toward development of a comprehensive biostratigraphic scheme for the Lower Ordovician of the North American platform. Samples collected at 25-ft intervals through the Arbuckle Group along and adjacent to Interstate Highway 35 on the south flank of the Arbuckle anticline near Ardmore, Oklahoma, produced conodonts in abundances ranging from a few tens to over a thousand elements per kilogram and displaying good to excellent preservation with low CAI. These conodonts document a biostratigraphic continuum that provides a standard for correlation of Lower Ordovician rocks in the subsurface of central US and of the many localized and incomplete outcrops of generally equivalent strata in the Ozark and Upper Mississippi Valley regions. The stratigraphic continuity of the collections makes the I-35 section an ideal standard reference section for graphic correlation of Lower Ordovician rocks containing conodonts of the Mid-Continent Province.

    To characterize mortality associated with injuries and other health problems in Oklahoma, we examined data from the Office of the Chief Medical Examiner of the State of Oklahoma for the years 1978 through 1984. Each year, approximately 1,500 and 800 deaths resulted from unintentional injury (UI) and intentional injury (ie, suicide and homicide), respectively. The medical examiner (ME) data differed substantially from the state's vital statistics (VS); over the seven years, the ME records showed 2,021 (16%) fewer UI deaths than did the VS, as well as 24 (1%) more cases of suicide and 499 (23%) more cases of homicide. Rates for UI and suicide were highest for young adults and for the elderly; in contrast, rates for homicide were highest for young adults, and then decreased with age. For each of the three categories of injury-related deaths, rates for male subjects were approximately three times those for female subjects; rates also varied by race-ethnic group. Deaths due to UI and homicide occurred more often in the summer and on weekends, though suicides did not vary by month and were slightly more common on weekdays. This study indicates that ME data represent an important source of epidemiologic information for the surveillance and study of injury-related mortality. PMID:2772684

    Fundamental research related to organic geochemistry, fluid-rock interactions, and the processes by which fluids migrate through basins has long been a part of the U.S. Department of Energy Geosciences program. Objectives of this program were to emphasize those principles and processes which would be applicable to a wide range of problems associated with petroleum discovery, occurrence and extraction, waste disposal of all kinds, and environmental management. To gain a better understanding of the progress being made in understanding basinal fluids, their geochemistry and movement, and related research, and to enhance communication and interaction between principal investigators and DOE and other Federal program managers interested in this topic, this workshop was organized by the School of Geology and Geophysics and held in Norman, Oklahoma in November, 1991.

    An environmental evaluation was made of possible exposure to waste anesthetic gases at the Memorial Hospital of Southern Oklahoma, Ardmore, Oklahoma. The hospital has six surgery rooms and a recovery room. During this evaluation four of the six were in use. Samples were taken for ethrane, halothane, isoflurane, and nitrous-oxide Of 22 air samples taken, two exceeded the NIOSH criteria for ethrane of 0.5 parts per million (ppm); one exceeded NIOSH criteria for halothane of 0.5 ppm. None exceeded the isoflurane NIOSH criteria of 0.5 ppm. One exceeded the nitrous oxide standards of 25 ppm. No leaks were found in the anesthesia administering machine, pop off valve scavenging system, or any other area of the operating room. About 26 air changes per hour occurred in the operating rooms. The four elevated exposures were attributed to improper fit on an intubation tube and face masks. The authors conclude that a hazard from exposure to waste anesthetic gases did not exist at this facility.

    2013-12-01

    Drought is a challenge faced by communities across the United States, exacerbated by growing demands on water resources and climate variability and change. The Arbuckle-Simpson Aquifer (ASA) in south-central Oklahoma, situated in the heart of the Chickasaw Nation, is the state's only sole-source groundwater basin and sustains the Blue River, the state's only free-flowing river. The recent comprehensive hydrological studies of the aquifer indicate the need for sustainable management of the amount of water extracted. However, the question of how to deal with that management in the face of increasing drought vulnerability, diverse demands, and climate variability and change remains. Water management carries a further imperative to be inclusive of tribal and non-tribal interests. To examine this question, we are conducting an investigation of drought risk from multiple disciplines. Anthropological data comes from stakeholder interviews that were designed to investigate conflict over water management by understanding how people perceive risk differently based on different opinions about the structure of the resource, varying levels of trust in authorities, and unequal access to resources. . The Cultural Theory of Risk is used to explain how people view risks as part of their worldviews and why people who hold different worldviews disagree about risks associated with water availability. Meteorological analyses of longitudinal data indicate periods of drought that are noted in stakeholder interviews. Analysis of stream gauge data investigates the influence of climate variability on local hydrologic impacts, such as changing groundwater levels and streamflows, that are relevant to planning and management decisions in the ASA. Quantitative assessment of future drought risk and associated uncertainty and their effect on type and scale of future economic and social impacts are achieved by combining elements of statistical and dynamical downscaling to improve predictions of local impacts using Hybrid Statistical-Dynamical Downscaling Technique.

    Water is central to life and earth processes, connecting physical, biological, chemical, ecological, and economic forces across the landscape. The vast scope of hydrologic sciences requires research efforts worldwide and across a wide range of disciplines. While hydrologic processes and scientific investigations related to sustainable agricultural systems are based on universal principles, research to understand processes and evaluate management practices is often site-specific to achieve a critical mass of expertise and research infrastructure to address spatially, temporally, and ecologically complex systems. In the face of dynamic climate, market, and policy environments, long-term research is required to understand and predict risks and possible outcomes of alternative scenarios. This special section describes the USDA-ARS's long-term research (1961 to present) in the Upper Washita River basin of Oklahoma. Data papers document datasets in detail (weather, hydrology, physiography, land cover, and sediment and nutrient water quality), and associated research papers present analyses based on those data. This living history of research is presented to engage collaborative scientists across institutions and disciplines to further explore complex, interactive processes and systems. Application of scientific understanding to resolve pressing challenges to agriculture while enhancing resilience of linked land and human systems will require complex research approaches. Research areas that this watershed research program continues to address include: resilience to current and future climate pressures; sources, fate, and transport of contaminants at a watershed scale; linked atmospheric-surface-subsurface hydrologic processes; high spatiotemporal resolution analyses of linked hydrologic processes; and multiple-objective decision making across linked farm to watershed scales.

    The environmental and hydrologic setting of the Ozark Plateaus National Water-Quality Assessment (NAWQA) study unit and the factors that affect water quality are described in this report. The primary natural and cultural features that affect water- quality characteristics and the potential for future water-quality problems are described. These environmental features include climate, physio- graphy, geology, soils, population, land use, water use, and surface- and ground-water flow systems. The study-unit area is approximately 47,600 square miles and includes most of the Ozark Plateaus Province and parts of the adjacent Osage Plains and Mississippi Alluvial Plain in parts of Arkansas, Kansas, Missouri, and Oklahoma. The geology is characterized by basement igneous rocks overlain by a thick sequence of dolomites, limestones, sandstones, and shales of Paleozoic age. Land use in the study unit is predominantly pasture and forest in the southeastern part, and pasture and cropland in the northwestern part. All or part of the White, Neosho-lllinois, Osage, Gasconade, Meramec, St. Francis, and Black River Basins are within the study unit. Streams in the Boston Mountains contain the least mineralized water, and those in the Osage Plains contain the most mineralized water. The study unit contains eight hydrogeologic units including three major aquifers--the Springfield Plateau, Ozark, and St. Francois aquifers. Streams and aquifers in the study unit generally contain calcium or calcium-magnesium bicarbonate waters. Ground- and surface-water interactions are greatest in the Salem and Springfield Plateaus and least in the Boston Mountains and Osage Plains. Geology, land use, and population probably are the most important environmental factors that affect water quality.

    ARC/INFO export and nonproprietary format files This diskette contains digitized aquifer boundaries and maps of hydraulic conductivity, recharge, and ground-water level elevation contours for the Elk City aquifer in western Oklahoma. The aquifer covers an area of approximately 193,000 acres and supplies ground water for irrigation, domestic, and industrial purposes in Beckham, Custer, Roger Mills, and Washita Counties along the divide between the Washita and Red River basins. The Elk City aquifer consists of the Elk City Sandstone and overlying terrace deposits, made up of clay, silt, sand and gravel, and dune sands in the eastern part and sand and gravel of the Ogallala Formation (or High Plains aquifer) in the western part of the aquifer. The Elk City aquifer is unconfined and composed of very friable sandstone, lightly cemented with clay, calcite, gypsum, or iron oxide. Most of the grains are fine-sized quartz but the grain size ranges from clay to cobble in the aquifer. The Doxey Shale underlies the Elk City aquifer and acts as a confining unit, restricting the downward movement of ground water. All of the data sets were digitized and created from information and maps in a ground-water modeling thesis and report of the Elk City aquifer. The maps digitized were published at a scale of 1:63,360. Ground-water flow models are numerical representations that simplify and aggregate natural systems. Models are not unique; different combinations of aquifer characteristics may produce similar results. Therefore, values of hydraulic conductivity and recharge used in the model and presented in this data set are not precise, but are within a reasonable range when compared to independently collected data.

  20. Permian evaporites in the Permian basin of southwestern United States

    Johnson, K.S.

    1997-01-01

    During Permian time, a broad and shallow inland sea covered much of southwestern United States, extending northward from west Texas into northwestern Kansas. Slow but continual subsidence beneath all parts of this vast Permian basin caused deposition of a thick sequence of Permian red beds and evaporites, including dolomite, gypsum/anhydrite, salt, and potash. Evaporite units are notably thick and laterally persistent throughout the Permian basin. The entire Permian System ranges up to 2,000 m thick in various parts of the basin, and individual formations, consisting mostly of gypsum/anhydrite and salt, commonly are 60-500 m thick. Evaporite deposits are oldest in the northern part of the Permian basin, and they generally are progressively younger toward the south. The site of principal salt deposition during early Leonardian time (Wellington evaporites) was in Kansas and northwestern Oklahoma; it then shifted southward into western Oklahoma and the Texas Panhandle during late Leonardian and early Guadalupian time (Lower Clear Fork/Lower Cimarron evaporites, Upper Clear Fork/Upper Cimarron evaporites, and San Andres/Blaine evaporites); and finally into west Texas and southeastern New Mexico during late Guadalupian and Ochoan time (Artesia, Castile, Salado, and Rustler evaporites). These evaporites comprise a significant resource for the region: rock salt is produced from dry mines, brine fields, and solar-salt operations at 18 locations; gypsum is mined at 13 sites; potash is produced from 5 underground mines in the world-famous Carlsbad potash district; and sulfur is produced by the Frasch process at one site.

  1. Frontal passage and cold pool detection using Oklahoma Mesonet observations

    NASA Astrophysics Data System (ADS)

    Lesage, Andrew T.

    For over a dozen years the Oklahoma Mesonet network has provided surface observations at over 100 stations. These observations are used to analyze mass flux estimates from surface divergence, frontal passages, and cold pools, the latter defined herein as active regions where precipitation processes are creating near-surface cold air masses. Case studies are detailed and a 15-yr climatology of frontal passages and cold pools was computed in this research. Convergence, divergence, and precipitation are most strongly correlated in the summer months and least correlated in the winter months. Wet spring and summer days had the highest average convergence and divergence values while dry summer and fall days had the lowest average convergence and divergence. Frontal passages and cold pools are tracked throughout the Mesonet in various case studies, four of which are covered herein. The methodology is able to represent front location and cold pool areas quite well despite the low resolution of the Mesonet grid. The climatology of front and cold pool data yielded many similarities. Winter has the largest magnitude changes in DeltaT, DeltaP, and Deltah/cp while spring and fall had the largest magnitude change in Deltaqv. Summer has the lowest with the exception of spring DeltaT. Correlations between these variables are lowest in the more convectively active summer season. Convergence is roughly equal ahead of fronts from spring through fall; however, divergence is present in summer frontal passages earlier and stronger compared to the other seasons. Fronts and cold pools are most likely to occur in summer and spring with summer having the highest percentage of fronts which lead to cold pools. Fronts and cold pools are substantially more likely to occur during the late afternoon and early evening in the summer; other seasons had a slighter nocturnal increase in frequency. Western Oklahoma had higher frequencies of frontal passages and cold pools than Eastern Oklahoma with frontal passages having the stronger signal. These findings help identify seasonal, diurnal, and geographic distributions of fronts and cold pools and can be used in modeling studies to better the understanding of cold pool processes and parameterizations.

    A regional frequency analysis was conducted to estimate the depth-duration frequency of precipitation for 12 durations in Oklahoma (15, 30, and 60 minutes; 1, 2, 3, 6, 12, and 24 hours; and 1, 3, and 7 days). Seven selected frequencies, expressed as recurrence intervals, were investigated (2, 5, 10, 25, 50, 100, and 500 years). L-moment statistics were used to summarize depth-duration data and to determine the appropriate statistical distributions. Three different rain-gage networks provided the data (15minute, 1-hour, and 1-day). The 60-minute, and 1-hour; and the 24-hour, and 1-day durations were analyzed separately. Data were used from rain-gage stations with at least 10-years of record and within Oklahoma or about 50 kilometers into bordering states. Precipitation annual maxima (depths) were determined from the data for 110 15-minute, 141 hourly, and 413 daily stations. The L-moment statistics for depths for all durations were calculated for each station using unbiased L-mo-ment estimators for the mean, L-scale, L-coefficient of variation, L-skew, and L-kur-tosis. The relation between L-skew and L-kurtosis (L-moment ratio diagram) and goodness-of-fit measures were used to select the frequency distributions. The three-parameter generalized logistic distribution was selected to model the frequencies of 15-, 30-, and 60-minute annual maxima; and the three-parameter generalized extreme-value distribution was selected to model the frequencies of 1-hour to 7-day annual maxima. The mean for each station and duration was corrected for the bias associated with fixed interval recording of precipitation amounts. The L-scale and spatially averaged L-skew statistics were used to compute the location, scale, and shape parameters of the selected distribution for each station and duration. The three parameters were used to calculate the depth-duration-frequency relations for each station. The precipitation depths for selected frequencies were contoured from weighted depth surfaces to produce maps from which the precipitation depth-duration-frequency curve for selected storm durations can be determined for any site in Oklahoma.

    Organic wastes, in particular fecal material, are qualified as one of the major causes of water quality deterioration. Their accumulation in water bodies may increase algal proliferation and eutrophication and the number of pathogenic organisms, which are responsible for many intestinal diseases especially when the water is used for recreational activities and/or as a supply for drinking water. In order to estimate the risk level associated with primary body contact in recreational water bodies, enumeration of some specific micro-organisms, such as Enterococci and Escherichia coli, are commonly used. Sterol distributions can provide some relevant information on the origin of fecal material in water system, since they are ubiquitous organic compounds and their distributions in many warm-blooded animal feces can be used as evidence for their source. In this study, we monitored fecal material contamination in three Oklahoma watersheds based on sterol fingerprints over a one-year period (2012 ~ 2013). The sterols from sediments and water samples (sterols associated to suspended particles as well as free sterols in water) were recovered using sonication and solid phase extraction (SPE), respectively, using different organic solvents. They were then identified and quantified by gas chromatography - mass spectrometry (GC-MS) using an internal standard. The GC-MS was previously calibrated with a sterol mixture injected at different concentrations. Our primary results show that the concentration of total sterols generally increases from the Upper Canadian < Neosho Grand < Cimarron - Upper Arkansas Basins in Oklahoma. The fecal sterols commonly represent a small proportion (<15%) within the total sterols quantified in these three basins. Their distributions show a significant contribution from herbivore feces. By means of this monitoring, we are able to determine the presence of fecal contamination and provide a better understanding on the ability of using sterol fingerprints to determine the origin of the fecal contamination. Additionally, such a sampling strategy, over a one-year period at regular intervals, enable us to track the water contamination by feces according to the seasonal climatic variations such as drought or heavy rainfall events.

    On June 15, 2004, Oklahoma became the first state to reclassify pseudoephedrine as a Schedule V drug. Arrests in Oklahoma for the manufacture of methamphetamines in clandestine laboratories precipitously declined. It was hypothesized that a decrease in methamphetamine use could be shown in the patient population in Oklahoma's largest emergency department. To test this hypothesis, all urine drug screen results in the Saint Francis Hospital Trauma Emergency Center from January 2003 through May 2005 were reviewed. There was a significant increase in the total tests performed and the percentage of positive test results for the amphetamine drug class (p = 0.0004, R2 = 0.3785) over time. These results suggest that methamphetamine usage has not decreased in the emergency department patient population. Possibly, methamphetamine usage in Oklahoma has not been impacted by the passage of HB 2176 due to an increase in drug trafficking of methamphetamine into the state. PMID:18183861

    West Carney field--one of the newest fields discovered in Oklahoma--exhibits many unique production characteristics. These characteristics include: (1) decreasing water-oil ratio; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods by which we can extend the phenomenon to other fields with similar characteristics. In our experimental investigation section, we continue to describe the use of surfactant to alter the wettability of the rock. By altering the wettability, we may be able to recover additional oil through imbibition and gravity drainage process.

    In late 2009, the seismicity of Oklahoma increased dramatically. The largest of these earthquakes was a series of three damaging events (Mw 4.8, 5.6, 4.8) that occurred over a span of four days in November 2011 near the town of Prague in central Oklahoma. Studies suggest that these earthquakes were induced by reactivation of the Wilzetta fault due to the disposal of waste water from hydraulic fracturing ("fracking") and other oil and gas activities. The Wilzetta fault is a northeast trending vertical strike-slip fault that is a well known structural trap for oil and gas. Since the November 2011 Prague sequence, thousands of small to moderate (M2-M4) earthquakes have occurred throughout central Oklahoma. The most active regions are located near the towns of Stillwater and Medford in north-central Oklahoma, and Guthrie, Langston and Jones near Oklahoma City. The USGS, in collaboration with the Oklahoma Geological Survey and the University of Oklahoma, has responded by deploying numerous temporary seismic stations in the region in order to record the vigorous aftershock sequences. In this study we use data from the temporary seismic stations to re-locate all Oklahoma earthquakes in the USGS National Earthquake Information Center catalog using a multiple-event approach known as hypo-centroidal decomposition that locates earthquakes with decreased uncertainty relative to one another. Modeling from this study allows us to constrain the detailed geometry of the reactivated faults, as well as source parameters (focal mechanisms, stress drop, rupture length) for the larger earthquakes. Preliminary results from the November 2011 Prague sequence suggest that subsurface rupture lengths of the largest earthquakes are anomalously long with very low stress drop. We also observe very high Q (~1000 at 1 Hz) that explains the large felt areas and we find relatively low b-value and a rapid decay of aftershocks.

    A new, 0.6-m robotic telescope of Ritchey-Chrtien design was recently installed at the H. S. Mendenhall Observatory (HSMO) of Oklahoma State University (OSU), and is now undergoing operational tests. Funded by the Air Force Office of Scientific Research through the Defense University Research Instrumentation Program, it replaces HSMO's original 0.35-m Schmidt-Cassegrain telescope. Research programs will include the characterization of near-Earth objects and collaborative searches for transiting exoplanets, programs which will also open up new research opportunities for students in the Oklahoma-Arkansas region. Ideally, these opportunities will attract more undergraduate and graduate students to major in physics and astronomy, and foster the creation of degree programs in astronomy at OSU. Optical Guidance Systems was the contractor for both the telescope and dome automation. The telescope's ceramic 602-mm f/3 primary and 220-mm secondary mirrors yield an effective focal ratio of f/8 that can be changed to f/5.3 with a focal reducer / field flattener. Fields of view range from 0.75 at f/5.3 to 1.2 at f/8. The Strehl ratio is 0.954. The telescope's carbon-fiber Serrurier truss is supported by an equatorial fork mount equipped with friction drives. Telescope equipment includes a 35-mm-format CCD camera with UBVRI filters, field rotator, off-axis guider, and flip-mirror unit for quick switches to eyepiece observing. HSMO itself is conveniently located under reasonably dark skies at an elevation of 340 m about 15 km southwest of the city of Stillwater, whose population, including OSU, is approaching 50,000. HSMO's dome was completed in 2002, and funding is being raised for a control building near the dome. The observatory's URL is www.physics.okstate.edu/observatory.

  13. Forensic Seismology and the 1995 Oklahoma City Terrorist Bombing

    2002-05-01

    The terrorist bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, on April 19, 1995, was recorded on 2 permanent seismographs, 7 and 26 km away. The more distant seismograph recorded 2 low-frequency wave trains separated by about 10 s. Militia groups speculated that the 2 wave trains were caused by separate explosions and hinted at a government cover up. Preliminary statements by the scientific community also contributed to the uncertainty. A public science organization issued a press release that stated "the location and source of the second surface wave-recording is unknown. Detailed investigations at the building site may offer an explanation as to the cause and origin of the second event." A prominent professional newsletter reported that the "first event was caused by energy from the explosion and the second from the fall of the building." To understand the seismic phases in the April 19 seismograms, the USGS monitored the demolition of the damaged building on May 23, 1995, with a portable seismic array. The array recorded the same 2 wave trains during the demolition and indicated the wave trains were a propagation effect and not the result of multiple sources. Modeling of the waveforms indicated that the 2 wave trains probably resulted from propagation of seismic energy in a near-surface zone with a strong velocity gradient. The first phase appeared to be a packet of scattered body waves and the second was the fundamental-mode Rayleigh wave. Timely resolution of the ambiguity of the seismogram and publication of results in a refereed publication, EOS, discouraged a conspiracy defense by the terrorists.

  14. Petroleum production and exploration in Ouachita region of Oklahoma

    Petroleum production in the Ouachita region of southeastern Oklahoma occurs in three geographic areas parallel to regional structure. The frontal gas, central oil, and central gas belts are distinguished by differences in structural setting, reservoir strata, and types of hydrocarbons. In the frontal belt, nearly 1 trillion ft/sup 3/ of dry gas has been produced from thrusted and subthrust Morrowan and Atokan sandstone and carbonate reservoirs. Over 8000 bbl of oil have been produced in the central oil belt, southeast of the Ti Valley fault. Structures consist of imbricate thrusts and isoclinal to overturned folds. The fields are typically small, associated with asphaltite or tar sands, and produce from Carboniferous sandstone reservoirs. Farther southeast, small fields within the central gas belt have produced minor gas from Ordovician, Devonian, and Mississippian reservoirs. Six Ordovician through Mississippian Ouachita-facies shales are potential petroleum source rocks and occur in the middle to lower part of the oil window. However, Devonian and Mississippian strata are composed primarily of terrestrial organic matter and are probably gas prone. Oil in Carboniferous reservoirs probably migrated upward stratigraphically from older sources. Recent exploration has focused on extending production from Pennsylvanian reservoirs in the frontal gas belt. However, a significant Arbuckle discovery (ARCO 2 Yourman) and a Broken Bow uplift test (Sohio 1-22 Weyerhauser) in 1987 indicate that Cambrian-Ordovician Arbuckle Group carbonates may be prospective beneath all of the Oklahoma Ouachitas. Near-future rank-wildcat exploration will probably focus on subthrust, structurally and stratigraphically favorable Arbuckle plays.

  17. Distributions of median nutrient and chlorophyll concentrations across the Red River Basin, USA.

    2010-01-01

    Acquisition and compilation of water-quality data for an 11-yr time period (1996-2006) from 589 stream and river stations were conducted to support nutrient criteria development for the multistate Red River Basin shared by Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. Ten water-quality parameters were collected from six data sources (USGS, Arkansas Department of Environmental Quality, Louisiana Department of Environmental Quality, Oklahoma Conservation Commission, Oklahoma Water Resources Board, and Texas Commission on Environmental Quality), and an additional 13 parameters were acquired from at least one source. Median concentrations of water-quality parameters were calculated at each individual station and frequency distributions (minimum, 10th, 25th, 50th, 75th, 90th percentiles, and maximum) of the median concentrations were calculated. Across the Red River Basin, median values for total nitrogen (TN), total phosphorus (TP), and sestonic chlorophyll-a (chl-a) ranged from < 0.02 to 20.2 mg L(-1), < 0.01 to 6.66 mg L(-1), and 0.10 to 262 microg L(-1), respectively. Overall, the 25th percentiles of TN data specific to the Red River Basin were generally similar to the USEPA-recommended ecoregion nutrient criteria of 0.31 to 0.88 mg L(-1), whereas median TP and chl-a data specific to the Red River Basin showed 25th percentiles higher than the USEPA-recommended criteria (0.010-0.067 mg TP L(-1); 0.93-3.00 microg chl-a L(-1)). The unique location of the Red River Basin in the south-central United States places it near the boundaries of several aggregate ecoregions; therefore, the development of ecoregion nutrient criteria likely requires using data specific to the Red River Basin, as shown in these analyses. This study provided basin-specific frequency distribution of median concentrations of water-quality parameters as the first step to support states in developing nutrient criteria to protect designated uses in the multijurisdictional Red River Basin.

    The Fort Cobb Reservoir Watershed (FCRW) (830 km2) is a watershed within the HELP Washita Basin, located in Caddo and Washita Counties, OK. It is also a benchmark watershed under USDA's Conservation Effects Assessment Project, a national project to quantify environmental effects of USDA and other conservation programs. Population in south-western Oklahoma, in which FCRW is located, is sparse and decreasing. Agricultural focuses on commodity production (beef, wheat, and row crops) with high costs and low margins. Surface and groundwater resources supply public, domestic, and irrigation water. Fort Cobb Reservoir and contributing stream segments are listed on the Oklahoma 303(d) list as not meeting water quality standards based on sedimentation, trophic level of the lake associated with phosphorus loads, and nitrogen in some stream segments in some seasons. Preliminary results from a rapid geomorphic assessment results indicated that unstable stream channels dominate the stream networks and make a significant but unknown contribution to suspended-sediment loadings. Impairment of the lake for municipal water supply, recreation, and fish and wildlife are important factors in local economies. The Thika River Watershed (TRW) (867 km2) is located in central Kenya. Population in TRW is high and increasing, which has led to a poor land-population ratio with population densities ranging from 250 people/km2 to over 500 people/km2. The poor land-population ratio has resulted in land sub-division, fragmentation, over- cultivation, overgrazing, and deforestation which have serious implications on soil erosion, which poses a threat to both agricultural production and downstream reservoirs. Agricultural focuses mainly on subsistence and some cash crops (dairy cattle, corn, beans, coffee, floriculture and pineapple) farming. Surface and groundwater resources supply domestic, public, and hydroelectric power generation water. Thika River supplies 80% of the water for the city of Nairobi. A dam was constructed in 1994 with a water reservoir of 70 million m3. Thika River also supplies water to Masinga Reservoir to supply the seven forks dams, which together supply 75% of the nation's electricity. The quantity of water in rivers and reservoirs is decreased due to sedimentation while water quality is degraded by sediments, and sediment-borne nutrients and pesticides. The focus of this pilot twinning project is watershed erosion and reservoir sedimentation assessment. This will be accomplished by (1) a rapid watershed/catchment erosion assessment using ground based measurements and remote sensing/GIS techniques, 2) use of Acoustic Profiling Systems (APS) for reservoir sedimentation measurement studies, and 3) advanced water quality modeling using the soil and water assessment tool (SWAT) model. Data acquired will be used for sediment transport modeling to1) determine sediment "hot spots" and management practices that will minimize sediments into reservoirs in order to 2) maintain the reservoirs on which many farmers depend for their livelihood and a cleaner environment. This project will provide an opportunity for 1) sharing knowledge and experience among the stakeholders, 2) building capacity through formal and informal education opportunities through reciprocal hosting of decision makers and water experts, and 3) technology transfer of pilot results with recommended management practices to reduce reservoir sedimentation rates.

  19. Rotational reflectance of dispersed vitrinite from the Arkoma basin

    1997-01-01

    Rotational reflectance of dispersed vitrinite provides superior documentation of thermal maturity and a capability for interpreting relative timing between thermal and kinematic events in Arkoma Basin strata characterized by vitrinite reflectances up to 5%. Rotational reflectance (R(rot)) is a more precise and less ambiguous index of thermal maturity than maximum (R'(max)), minimum (R(min)), and random (R(ran)) reflectance. Vitrinite reflectance anisotropy becomes sufficiently large to be measurable (using a microscope equipped with an automated rotating polarizer) at ???2% R(rot) and increases following a power function with increasing thermal maturity. Rotational reflectance data can be used to infer the shape of the vitrinite reflectance indicating surface (i.e. indicatrix) and, in turn, to enhance interpretations of the timing between thermal maxima and compressional tectonic events. Data from three wells in the Arkoma Basin Ouachita frontal thrust belt are used as examples. The absence of offsets in measured R(rot) across thrust faults combined with a predominance of uniaxial vitrinite in the thrust faulted part of the section suggest thermal maximum postdated thrust faulting in the western Ouachita frontal thrust belt of Oklahoma. In contrast, the general absence of offsets in measured R(rot) across thrust faults combined with a predominance of biaxial vitrinite in the thrust faulted part of the section suggest that the thermal maximum was coeval with thrust faulting in the eastern Ouachita frontal thrust belt of Arkansas. The presence of biaxial vitrinite in an allochthonous section and uniaxial vitrinite in an underlying, autochthonous section suggests that the thermal maximum was coeval with listric thrust faulting in the central Arkoma Basin of Oklahoma, and that rotational reflectance data can be used as a strain indicator to detect subtle decollement zones.

  20. Quantifying the distribution of nanodiamonds in pre-Younger Dryas to recent age deposits along Bull Creek, Oklahoma Panhandle, USA

    High levels of nanodiamonds (nds) have been used to support the transformative hypothesis that an extraterrestrial (ET) event (comet explosion) triggered Younger Dryas changes in temperature, flora and fauna assemblages, and human adaptations [Firestone RB, et al. (2007) Proc Natl Acad Sci USA 104(41):1601616021]. We evaluate this hypothesis by establishing the distribution of nds within the Bull Creek drainage of the Beaver River basin in the Oklahoma panhandle. The earlier report of an abundance spike of nds in the Bull Creek I Younger Dryas boundary soil is confirmed, although no pure cubic diamonds were identified. The lack of hexagonal nds suggests Bull Creek I is not near any impact site. Potential hexagonal nds at Bull Creek were found to be more consistent with graphene/graphane. An additional nd spike is found in deposits of late Holocene through the modern age, indicating nds are not unique to the Younger Dryas boundary. Nd distributions do not correlate with depositional environment, pedogenesis, climate perturbations, periods of surface stability, or cultural activity. PMID:24449875
