    Andrews, F.L.; Wells, F.C.; Shelby, W.J.; McPherson, E.M.

    1988-01-01

    Lake Austin and Town Lake are impoundments on the Colorado River in Travis County, central Texas, and are a source of water for municipal industrial water supplies, electrical-power generation, and recreation for more than 500,000 people in the Austin metropolitan area. Small vertical temperature variations in both lakes were attributed to shallow depths in the lakes and short retention times of water in the lakes during the summer months. The largest areal variations in dissolved oxygen generally occur in Lake Austin during the summer as a result of releases of water from below the thermocline in Lake Travis. Except for iron, manganese, and mercury, dissolved concentrations of trace elements in water collected from Lake Austin and Town Lake did not exceed the primary or secondary drinking water standards set by the US Environmental Protection Agency. Little or no effect of stormwater runoff on temperature, dissolved oxygen, or minor elements could be detected in either Lake Austin or Town Lake. Little seasonal or areal variation was noted in nitrogen concentrations in Lake Austin or Town lake. Total phosphorus concentrations generally were small in both lakes. Increased concentrations of nitrogen and phosphorus were detected after storm runoff inflow in Town Lake, but not in Lake Austin; densities of fecal-coliform bacteria increased in Lake Austin and Town Lake, but were substantially greater in Town Lake than in Lake Austin. 18 refs., 38 figs., 59 tabs.

    The Austin Chalk is a carbonate limestone which has major outcropping near Austin, Texas. Around Austin, San Antonio, and San Marcos it finds its major expression in the so-called Balcones Escarpment, a jutting limestone promontory that divides the Texas hill country from the Black Gumbo Farmland to the east, and forms one of the longest, most noticeable geologic features in the state. The Chalk is known to run through the entire Gulf Coast Littoral - Louisiana, Mississippi, and Alabama. A map shows the locations of the major uplifts, downwarps, fault zones, and tectonic belts in the Austin Chalk play.

  18. Outbreak of Rickettsia typhi infection - Austin, Texas, 2008.

    PubMed

    2009-11-20

    Murine typhus is a fleaborne rickettsial disease caused by the organism Rickettsia typhi. Symptoms include fever, headache, chills, vomiting, nausea, myalgia, and rash. Although murine typhus is endemic in southern Texas, only two cases had been reported during the past 10 years from Austin, located in central Texas. On August 8, 2008, the Austin/Travis County Department of Health and Human Services (ATCDHHS) contacted the Texas Department of State Health Services (TDSHS) concerning a cluster of 14 illnesses with serologic findings indicative of murine typhus. On August 12, 2008, TDSHS initiated an investigation with assistance from CDC to characterize the magnitude of the outbreak and assess potential animal reservoirs and peridomestic factors that might have contributed to disease. This report summarizes the clinical and environmental findings of that investigation. Thirty-three confirmed cases involved illness comparable to that associated with previous outbreaks of murine typhus. Illness ranged from mild to severe, with 73% of patients requiring hospitalization. Delayed diagnosis and administration of no or inappropriate antibiotics might have contributed to illness severity. Environmental investigation suggested that opossums and domestic animals likely played a role in the maintenance and spread of R. typhi; however, their precise role in the outbreak has not been determined. These findings underscore the need to increase awareness of murine typhus and communicate appropriate treatment and prevention measures through the distribution of typhus alerts before and throughout the peak vector season of March-November.

    1991-03-01

    Ichnofossils are abundant in outcrops of the Austin Chalk near Waxahachie, Texas (designated site of the Super-Conducting Super Collider). The abundance and diversity of ichnofossils in Austin strata contrast with the paucity of other macrofossils, except large inoceramids. The lower Austin Chalk (Coniacian) disconformably overlies the Eagle Ford Shale (Turonian). Planolites, Thalassinoides, and Chondrites are conspicuous in the lower Austin. Some lower Austin strata contain well-preserved burrows having menicus fillings. However, most lower Austin ichnofossils are poorly preserved and have compacted. The middle Austin Marl and upper Austin Chalk (Santonain) contain Planolites, Chondrites, Thalassinoides, and Pseudobilobites. Several thin, intensely burrowed, Fe-stained, horizons within the middle Austin represent omission surfaces having postomission Thalassinoides. The upper Austin disconformably underlies the Taylor Marl (Campanian). The Austin-Taylor contact is a Rhizocorallium-infested omission surface overlain by a condensed bed of phosphatic and pyritic bioclasts. Upper Austin occurrences of Rhizocorallium and Pseudobilobites are unique for North American Cretaceous chalks. Based on cross-cutting relationships and differences in morphology, diameter, and burrow-filling sediments, numerous ichnospecies of Thalassinoides are discernable throughout the Austin. Variations in preservation quality exhibited by successive generations of ichnofossils record progressive changes in substrate consistency. Earliest formed burrows have diffuse outlines representing an initial thixotropic (softground) Austin substrate. Subsequent generations of burrows have more distinct outlines recording a gradual increase in substrate firmness. Paleo-firmgrounds are common in Austin outcrops; evidence of hardgrounds is lacking. The Thalassinoides-dominated Austin ichnoassemblage represents an inner shelf paleoenvironment.

  6. Fracture development and mechanical stratigraphy of Austin Chalk, Texas

    SciTech Connect

    Corbett, K.; Friedman, M.; Spang, J.

    1987-01-01

    The mechanical stratigraphy of the Upper Cretaceous Austin Chalk is established from study of fracture intensity along its outcrop trend from Dallas to San Antonio and westward to Langtry, Texas, and in the subsurface from study of cores and/or fracture identification logs from 30 wells. Three mechanical-stratigraphic units are recognized. Representative samples from the three mechanical-stratigraphic units were experimentally shortened, dry, at 10, 17, 34, and 70 MPa confining pressure, at 24/sup 0/C, and at a strain rate of 2.5 x 10/sup -4/ sec/sup -1/ to determine if the relative mechanical behavior observed at the surface could be extrapolated into the subsurface at different simulated burial depths. SEM photomicrographs of undeformed specimens show that smectite and other clays are distributed as large (30 ..mu..m), discrete, amorphous, concentrated masses throughout the chalk. They are comminuted along the induced fracture surfaces where their grain size is 0.5 ..mu..m or less. These observations suggest that smectite acts as a soft-inclusion, localizing shear failure and corresponding weakening the material. 9 figures, 5 tables.

  7. Positron research at the University of Texas at Austin

    NASA Astrophysics Data System (ADS)

    Goktepeli, Sinan

    The objective of the research presented in this dissertation is to advance the applications of positron annihilation research. An intense positron beam facility was designed and constructed, and a method was developed to better analyze the defect structure of solids. The Texas Reactor-based Intense Positron beam facility (TRIP) was designed to provide a monoenergetic/monodirectional beam of at least 108 e +/sec on a sample. This increase in beam intensity will enhance many positron research techniques both in atomic physics and materials science. The TRIP facility, the result of a collaboration between UT Austin and UT Arlington, is being developed around the concept of multiple scattering of positrons from solid krypton. A large area copper source will be irradiated in a beam port of the 1 MW TRIGA Mark-II research reactor at UT Austin. The source will form the bottom face of a cube with the remaining faces made of tungsten. All surfaces will be cooled down to 22 K and coated with krypton. The top face of the cube has a 1 cm diameter hole to allow for the passage of positrons. The fast beta particles emitted from the β+ decay of 64Cu will be moderated while passing through the krypton. The non- moderated positrons will lose their energy while interacting with the remaining walls. The positrons will be removed from the box by an electric field and electrostatically delivered to the sample. The work on the TRIP facility is ongoing. The results of early measurements at UT Arlington have shown that the facility will be able to achieve its goals. The method developed to better analyze the positron depth profiling (PDP) experiments uses the difference spectra of the measured Doppler broadened annihilation peaks. The difference spectra, which are obtained by subtracting the bulk peak shape from the peaks recorded for each incident positron energy, enhance the differences of the observed peaks, while removing the bulk annihilation term from the multi-state annihilation

  8. Austin Chalk (!) Petroleum System: Upper Cretaceous, Southeastern Texas

    SciTech Connect

    Dawson, W.C.; Katz, B.J.; Robison, V.D.

    1995-10-01

    The Austin Group (Coniacian-Santonian) is a sequence of interstratified chalk and marl deposited during a sea-level highstand as a transgressive unit. Austin Chalk deposition occurred on a southeastward-dipping carbonate ramp that exhibits distinctive onshore and offshore chalk lithofacies. Discrete intervals within offshore Austin lithofacies display good to excellent source rock potential. Organic carbon content ranges upward to 20.0 wt. % with generation potentials exceeding 45 mg HC/g of rock measured. Source potential increases basinward where offshore chalk units exhibit increases in both organic richness and net thickness. These organically rich units display an affinity for the Type II reference curve. Hydrogen index values typically exceed 300 mg HC/g TOC. Several geochemical indices suggest that the oil-window is located at relatively shallow depths (6,700 ft). Offshore chalks sourced onshore Austin reservoirs through lateral migration (along fractures and stylolites) which occurred during the middle Tertiary. Hydrocarbons may also have been sourced from the underlying Eagle Ford Shale (Turonian). Austin Shale reservoirs are characterized by low porosity/low permeability dual pore systems consisting of microporous matrix and fractures. Diagenesis (mechanical compaction, styloitization, and calcite cementation) has strongly modified Austin Chalk pore systems. Matrix porosity generally decreases with increasing depth because of progressive burial diagenesis. Austin reservoirs typically have two major sets of fractures; reservoir performance is related to fracture connectivity. Austin Chalk reservoirs are sealed by the overlying Taylor Marl (Campanian).

  9. Nature and significance of Austin-Taylor unconformity on western margin of east Texas basin

    SciTech Connect

    Surles, M.A. Jr.

    1984-04-01

    The Taylor Marl unconformably overlies the Austin Chalk on the western margin of the East Texas basin. Along this contact, up to 275 ft (84 m) of upper Austin is missing in the Waco area and up to 450 ft (137 m) in Bell County. However, the Austin Chalk appears to have been more-or-less uniformly deposited throughout the study area. Apparently regional uplift caused a regression that terminated Austin deposition and was related to the erosion of the upper Chalk. While the unconformity is areally extensive, slightly angular, and accounts for a relatively long period of time, the mechanism of erosion that caused the unconformity is still uncertain. Erosion was terminated by the deposition of the lower Taylor Marl. Taylor A, the lowermost subdivision of the lower Taylor, was deposited in a near-shore environment that was highly variable. Of particular interest is the relationship of this unconformity to structure and probably to oil occurrence in the Austin Chalk in McLennan and Falls Counties. Major Austin fracturing, which apparently does not extend into the Taylor in Falls County, clearly indicates that structure in the Chalk, at least in part, antedates Taylor deposition. Oil occurrence in the Chalk is clearly related to fracturing and probably is localized by post-Austin-pre-Taylor fracture systems.

  15. Cyclic sedimentation, synsedimentary volcanism, microfabrics, and fracture intensity in the Austin Chalk, Texas

    SciTech Connect

    Hovorka, S.D. )

    1992-01-01

    Pelagic depositional environments of the Austin Chalk (Coniacian-Santonian) were influenced by sea-level variation, planktonic productivity, and allochthonous detrital input. Subtle differences in chalk facies influence fracture intensity, therefore imposing stratigraphic variability on hydrologic properties of the Austin Chalk. Variations in fracture intensity may affect ground-water flow through the Superconducting Super Collider (SSC) site south of Dallas in the same way that they influence hydrocarbon production in South Texas. The lower Austin Chalk was deposited during transgression. Glauconitic sandstone is overlain by cyclic chalk containing chalk-filled channels. Meter-thick chalk/marl cycles have frequencies in the Milankovitch spectrum. Marl accumulated during episodes of decreased planktonic productivity. Maximum flooding is indicated by organic-rich marls in the upper part of the Lower Austin Chalk. Shallowing during deposition of the middle and upper Austin Chalk is indicated by increasing abundance of winnowed lag deposits and firm grounds, resulting in increased faunal diversity. Authigenic clay, a product of alteration of volcanic ash codeposited with the chalk and marl, increases ductility in the middle Austin Chalk. The stratigraphic distribution of authigenic clay corresponds to disseminated biotite, quartz, and feldspar phenocrysts in most samples of the middle Austing Chalk. Authigenic clay decreases porosity, influences porosity-permeability relationships, and provides a regionally traceable low SP log response that correlates with low fracture intensity.

  16. A unique Austin Chalk reservoir, Van field, Van Zandt County, Texas

    SciTech Connect

    Lowe, J.T. )

    1990-09-01

    Significant shallow oil production from the Austin Chalk was established in the Van field, Van Zandt County, in East Texas in the late 1980s. The Van field structure is a complexly faulted domal anticline created by salt intrusion. The Woodbine sands, which underlie the Austin Chalk, have been and continue to be the predominant reservoir rocks in the field. Evidence indicates that faults provided vertical conduits for migration of Woodbine oil into the Austin Chalk where it was trapped along the structural crest. The most prolific Austin Chalk production is on the upthrown side of the main field fault, as is the Woodbine. The Austin Chalk is a soft, white to light gray limestone composed mostly of coccoliths with some pelecypods. Unlike the Austin Chalk in the Giddings and Pearsall fields, the chalk at Van was not as deeply buried and therefore did not become brittle and susceptible to tensional or cryptic fracturing. The shallow burial in the Van field was also important in that it allowed the chalk to retain primary microporosity. The production comes entirely from this primary porosity. In addition to the structural position and underlying oil source from the Woodbine, the depositional environment and associated lithofacies are also keys to the reservoir quality in the Van field as demonstrated by cores from the upthrown and downthrown (less productive) sides of the main field fault. It appears that at the time of Austin Chalk deposition, the main field fault was active and caused the upthrown side to be a structural high and a more agreeable environment for benthonic organisms such as pelecypods and worms. The resulting bioturbation enhanced the reservoir's permeability enough to allow migration and entrapment of the oil. Future success in exploration for analogous Austin Chalk reservoirs will require the combination of a favorable environment of deposition, a nearby Woodbine oil source, and a faulted trap that will provide the conduit for migration.

  17. Trace fossils and paleoenvironments of lower and middle Austin Chalk (upper Cretaceous), north-central Texas

    Dawson, W.C. ); Reaser, D.F. )

    1990-09-01

    Outcrops of lower and middle Austin Chalk in the vicinity of Cedar Hill and Waxahachie, Texas (designated site of the Superconducting Super Collider), are profusely bioturbated. The lower Austin (Coniacian) disconformably overlies the Eagle Ford Shale (Turonian) and consists of about 60 m of medium- to thick-bedded indurated chalk with thin intervening marls. The middle Austin (Santonian) is composed of about 65 m of thick-bedded marl containing thin beds of argillaceous chalk. Both chalk and marl units are moderately to intensely bioturbated. However, ichnofossils are more conspicuous in chalks where multiple episodes of burrowing are recognizable. Early formed burrows (indistinct mottles) represent the initial softground Austin substrate. Later generations of well-preserved burrows record a post-compaction (dewatered) firmground substrate. No hardgrounds have been recognized. The abundance and diversity of ichnofossils in Austin strata are in marked contrast to the paucity of other megafauna, except large inoceramids. Planolites, Teichichnus, Thalassinoides, and Chondrites are the predominant ichnogenera in the lower Austin; these forms are superimposed on a background of nondiagnostic, irregularly shaped mottles. Some strata contain well-preserved J-, S-, T-, U-, Y-, and X-shaped traces having menicus fillings. These subhorizontal, endogenic, full-relief burrows are typically infilled with dark gray (pyritic) chalk. Locally, pyrite or Fe-oxide-filled vertical tubes are preserved. Many traces have been deformed by compaction. The middle Austin contains Planolites, Chondrites, Thalassinoides, Pseudobilobites, and both small- and large-diameter, sinuous, horizontal burrows. These ichnofossils are infilled with chalk or comminuted shells and are more resistant to weathering than the surrounding middle Austin marl. Intensely burrowed horizons occur in association with distinctive Fe-stained chalk beds.

The information will be useful in determining the extent to which progressive urbanization will affect the yeild and mode of occurrence of storm runoff. The major streams in the study area are the Colorado River, Onion Creek, Barton Creek, Walnut Creek, Bull Creek, Boggy Creek, Shoal Creek, Williamson Creek, Slaughter Creek, Bear Creek, and Waller Creek. Detailed rainfall-runoff computations are presented for eight storm periods during the 1979 water year. Water-quality data for sites in the Austin metropolitan area are also given in this report.

  1. Assessment of fracture-induced anisotropy in the Austin Chalk Formation (Upper Cretaceous), central Texas

    Edwards, D.A. )

    1990-05-01

    This study relates geophysical and geological data to the detection of fractures and their influence on the movement of fluid in the Atco Member of the Austin Chalk in central Texas. In areas of production, the Austin Chalk has very low matrix permeabilities, with hydrocarbons confined to zones of near-vertical, stress-aligned fractures. Horizontal drilling has been estimated to increase per well reserves in the Austin Chalk from 75,000 bbl and 82 mmcf to 500,000 bbl and 500 mmcf. The objective of deviated wells in the Austin Chalk is to intersect at right angles as many of the hydrocarbon-prone fracture zones as possible. Therefore, the detection and description of these fracture zones prior to drilling is critical. Fractures have been proven to influence the velocities of shear waves. To assess shear wave velocities in different directions, several shear wave refraction and three-component vertical seismic profiles have been acquired. These data provided a measure of the fracture-induced shear wave anisotropy and an indication of the dominant fracture trend. Other data, including azimuthal resistivity surveys, cores, and aerial photographs, provided additional control for evaluating the fractures. The final phase of the study compares the geophysical and geological interpretations to the result of shallow groundwater pumping tests. The pumping tests have been conducted in vertical boreholes and were designed to evaluate the influence of the fracturing on fluid movement.

  3. Horizontal exploitation of the Upper Cretaceous Austin Chalk of south Texas

    1990-05-01

    Horizontal drilling in the fractured Austin Chalk of south Texas has proven to be a viable technology for exploiting reserve opportunities in mature trends as well as in frontier areas. To date, the results of an interdisciplinary approach to the regional analysis of structure and stress regimes combined with studies of the depositional characteristics of the Austin Chalk and Eagleford Shale have been a success. Productive characteristics of the Austin Chalk indicate the influence of regional fractures on the preferential flow direction and partitioning in the Pearsall field area of the trend. Well bore orientation and inclination are designed such that multiple fracture swarms at several stratigraphic horizons are intersected with a single horizontal well bore. As a result of the greater frequency of fracture contacts with the well bore, there is a significant increase in the ultimate recovery of hydrocarbons in place. Conventional vertical drilling techniques are frequently ineffective at encountering these laterally partitioned fracture sets, resulting in lower volumes of recoverable hydrocarbons. Additionally, horizontal well bores may increase ultimate recovery of hydrocarbons by lowering the pressure gradient to the well bore and maximizing the reservoir energy.

  4. Application of thematic mapper imagery to oil exploration in Austin Chalk, central Gulf Coast basin, Texas

    SciTech Connect

    Reid, W.M.

    1988-02-01

    One of the newest major oil plays in the Gulf Coast basin, the Austin Chalk reportedly produces in three belts: an updip belt, where production is from fractured chalk in structurally high positions along faults above 7000 ft; a shallow downdip belt, where the chalk is uniformly saturated with oil from 7000 to 9000 ft; and a deeper downdip belt saturated with gas and condensate below 9000 ft. The updip fields usually occur on the southeastern, upthrown side of the Luling, Mexia, and Charlotte fault zones. Production is from fractures that connect the relatively sparse matrix pores with more permeable fracture systems. The fractures resulted from regional extensional stress during the opening of the Gulf Coast basin on the divergent margin of the North American plate during the Laramide orogeny. The fractures are more common in the more brittle chalk than in the overlying Navarro and underlying Eagle Ford shales, which are less brittle. The oil in the updip traps in the chalk may have been generated in place downdip, and migrated updip along the extension fractures into the updip traps during or after the Laramide orogeny. A fairway of previously unmapped updip faults and drag folds has been mapped using Thematic Mapper imagery and seismic, structural, and resistivity maps near the Nixon field, Burleson County, Texas. This fairway, prospective for oil from the Austin Chalk, contains wells reported to produce from the Austin Chalk which lie along lineaments and linear features on the Thematic Mapper imagery and faults in the seismic and structure maps.

  6. Dynamic depositional and early diagenetic processes in a deep-water shelf setting, upper cretaceous Austin Chalk, North Texas

    SciTech Connect

    Hovorka, S.D.; Nance, H.S.

    1994-12-31

    The Austin Chalk of north Texas was deposited on a deep-water shelf north of the Sea Marcos Platform during a worldwide Coniacian and Santonian sea-level highstand. Transgressive (lowermost lower Austin Chalk), highstand (uppermost lower Austin Chalk), and regressive (middle and upper Austin Chalk) phases of cyclic chalk and marl sedimentation are recognized in excavations and tunnels created in Ellis County for the Superconducting Super Collider provide new evidence of sediment transport during Austin Chalk deposition. During transgression, bottom currents syndepositionally reworked nannoplankton oozes, incising channels as much as 120 ft across and 8 ft deep. Weakly burrowed channel fills having preservation of fine lamination document rapid infilling. Channel fills are composed of pyritized and carbonized wood and Inoceramus lag deposits, pellets, echinoderm fragments, and globigerinid grainstones, and coccolith ooze. During maximum highstand, bottom reworking was suppressed. Detrital content of highstand marls is low (>20 percent); organic content is high (1.4 to 3.5 percent). Coccolith preservation is excellent because of minimal diagenetic alteration. Regression is marked by resumed channel cutting and storm-bed winnowing in the middle and upper Austin Chalk. Suppressed resistivity log response and recessive weathering characteristics of the middle Austin Chalk are not primarily related to depositional environment but rather to increased input of volcanic ash during the accumulation of this interval. Early stabilization of ash produced clay-coated microfabrics in sediments that are otherwise similar to the transgressive deposits.

  10. Sequential vein growth with fault displacement: An example from the Austin Chalk Formation, Texas

    NASA Astrophysics Data System (ADS)

    Lee, Young-Joon; Wiltschko, David V.; Grossman, Ethan L.; Morse, John W.; Lamb, William M.

    1997-10-01

    To determine the opening and precipitation history and characteristics of vein-forming fluids, analyses of oxygen and carbon isotopes and trace elements were carried out on multilayered crack-seal calcite veins in the Austin Chalk Formation near San Antonio, Texas. The veins developed within the normal fault zones possessing unique chemical and textural characteristics which indicate sequential vein development. They are composed of alternating millimeter- to submillimeter-thick calcite veinlets and host lithons, occasionally crosscut by coarse, equant-grained secondary calcite veins. Regular changes in δ18O (e.g., -2.6 to -5.6‰, Pee Dee belemnite (PDB)) of the calcite veinlets along the length of veins suggest that the individual calcite veinlets were sequentially developed. A systematic δ18O decrease in the vein opening direction primarily resulted from a continuous increase in temperature of the ascending fluids delivered to the Austin Chalk. Relatively constant δ13C (approximately +1.4±0.4‰, PDB) for the multilayered veins and most secondary veins indicates that the composition of fluids from which the calcite veins precipitated was initially buffered by the bulk chalk. There is no spatial variation in trace element composition of the calcite veinlets along the length of veins. Low Sr concentrations in both calcite veinlets and secondary veins relative to those of the host chalk reflect a low partition coefficient of Sr in calcite during vein formation. Normal faults in the Cretaceous Austin Chalk were conduits to upwardly mobile vein-forming fluids.

    Town Lake, the last in the chain of Highland Lakes on the Colorado River, runs through the center of Austin, Texas. On any given day, grebes and coots dot the water, rowers skim alongside, and the sparkle of the sun on the water can be admired from the adjacent hike and bike path and from the windows of nearby office buildings. During the summer months, crowds gather along the shores of Town Lake to watch as many as 1 million Mexican Free-Tail bats emerge from under the Congress Avenue bridge. But below the lazily moving azure water lies a bed of sediment about 1 meter (m) thick?sediment that has been deposited gradually since the reservoir was formed in 1959 and that has been recording changes in water quality since that time. What can this sediment tell us about the history of water quality in the Colorado River? And what does it say about the effects of the rapid urbanization of Austin and the future health of our environment?

    2013-12-01

    Periodic releases from an upstream dam cause rapid stage fluctuations in the Colorado River near Austin, Texas. These daily pulses modulate fluid exchange and residence times in the hyporheic region, where biogeochemical reactions have been found to be more pronounced. We have installed two transects of wells perpendicular to the river in order to further examine the reactions occurring in this zone of surface-water and groundwater exchange. One well transect records physical water level fluctuations and allows us to map hydraulic head gradients and fluid movement. The second transect allows for water sample collection at three discrete depths. Samples were collected on a regular (approximately hourly) basis from 12 wells for at least 24-hours and were analyzed for nutrients, carbon, major ions, and stable isotopes. The results will provide a detailed picture of biogeochemical processes in hyporheic zones driven by upstream dam operations.

    A demonstration compressed natural gas (CNG) bus has been operating on The University of Texas at Austin shuttle system since 1992. This CNG vehicle, provided by the Blue Bird Company, was an opportunity for the University to evaluate the effectiveness of a CNG bus for shuttle operations. Three basic operating comparisons were made: (1) fuel consumption, (2) tire wear, and (3) vehicle performance. The bus was equipped with a data logger, which was downloaded regularly, for trip reports. Tire wear was monitored regularly, and performance tests were conducted at the Natural Gas Vehicle Technology Center. Overall, the data suggest that fuel costs for the CNG bus are comparable to those for University diesel buses. This is a result of the lower fuel price for natural gas. Actual natural gas fuel consumption was higher for the CNG buses than for the diesel buses. Due to weight differences, tire wear was much less on the CNG buses. Finally, after installation of a closed-loop system, the CNG bus out-performed the diesel bus on acceleration, grade climbing ability, and speed.

    Selected water quality properties and constituents of stormflow and base flow at 18 sites on 11 streams in the Austin area, Texas, were compared to determine the relation between degree of urbanization and water quality. Sample sites were grouped into four development classifications based on percentage of impervious cover of the drainage basin. For each site and development classification, concentrations and densities of water quality properties and constituents in samples collected during base flow were compared. Except for dissolved solids, concentrations during the rising stage of stormflow generally were larger than during the falling stage. The concentrations in stormflow were larger than in base flow. For the five sites that had sufficient samples from each flow category for statistical comparisons, median concentrations in stormflow were significantly larger than in base flow. Concentrations in the rising stage were more variable and significantly larger than in the falling stage. Except for dissolved solids, median concentrations in samples collected during stormflow increased with increasing urbanization. Medians for base flow also were larger for more urban classifications. The ratio of the number of samples with detectable concentrations to total sample analyzed of 18 minor inorganic constituents and the concentrations of many of these constituents increased with increasing urbanization. Twenty-two of 42 synthetic organic compounds investigated were detected in one or more samples and were detected more frequently and in larger concentrations at sites with more urban classifications.

    The Center for Electromechanics at the University of Texas at Austin (CEM-UT) has developed, while performing research associated with several Defense Advanced Research Projects Agency (DARPA) contracts, a velocity dependent friction model that accurately predicts the losses associated with a plasma armature railgun. Test results from CEM-UT's 1 m long, 1.27 cm square bore, plasma-armature railgun have been used to determine the validity of the model. Deviation between calculated and measured performance is typically less than 5% at railgun currents below 500 kA, however, at currents greater than 500 kA, the deviation increases. Experimental evidence suggests that the railguns lack of stiffness and subsequent venting of driving pressure rather than the electromechanical model is primarily responsible for the divergence between predicted and measured results. To test this theory a railgun was built using external preloading rings (Ringfeder) to increase its stiffness. On the first test of the Ringfeder railgun, 625 kA was discharged into the gun and the projectile was accelerated to 5.9 km/s. Test data indicates that the projectile accelerated through the entire length of the railgun and that a minimum amount of plasma leakage occurred during the test. An analysis of the 625-kA test was done to compare the results of CEM-UT's frictional loss model to ablation and viscous drag loss models.

  1. The effects of urbanization on floods in the Austin metropolitan area, Texas

    Veenhuis, J.E.; Gannett, D.G.

    1986-01-01

    The effects of urbanization on flood peaks in streams in the Austin metropolitan area Texas were studied in two separate analyses. In the first analysis, annual peak discharge records at 13 streamflow gaging sites were used to compute a recorded flood frequency relation for each site. Rainfall and streamflow data for 10 to 20 storms for each of these sites were used to simulate 55 annual peak discharges. These simulated discharges also were used to develop a flood frequency relation at each site. The flood frequency relations from recorded and generated data were then combined by weighting the recorded flood frequency by the years of record at each site to produce a combined (or weighted) flood frequency at each site. Flood frequencies for all 13 sites were subsequently regressed against basin characteristics at each site to determine possible effects of urbanization. The regression analysis of the combined flood frequency data for the 13 sites yielded an equation for estimating floods of a given recurrence interval at ungaged sites in the Austin area, as a function of the contributing drainage area, the total impervious area percentage, and basin shape. The regression equation estimates that a near fully developed hypothetical drainage basin (impervious area percentage, 45%) would have discharges for the 2 yr and 100 yr recurrence interval that are 99% and 73% greater, respectively, than discharges for those frequencies from a rural drainage basin (impervious percentage, 0). In the second analysis, records at one streamflow gaging site on Waller Creek were analyzed for changes in rainfall-runoff and flood frequency relations due to urbanization. Annual peak discharges from 1956 to 1980 and data from a total of 80 storms at the Waller Creek site were analyzed. Both analyses showed increases comparable to those predicted using the equations developed from the 13-station analysis.

    The University of Texas at Austin has one of the largest astronomy graduate programs in the U.S. As of several years ago, there were over 50 students enrolled, although the current number is closer to 35. During the decade 1980-89, a total of 85 students entered the program, of whom 64 (75%) completed the Ph.D. About a third (33%) of the Ph.D. graduates currently hold postdoctoral positions in astronomy. (Note that the sample includes some students who received their degrees within the last four or five years.) Another 35% hold permanent (or tenure-track) faculty jobs or positions at government laboratories or observatories in the U.S.; if one includes those who hold such positions in other countries, the total rises to 45%. (Some of these were foreign students who returned to their country of origin.) The remaining individuals are supported by grants (``soft money'') or are employed by companies doing work mostly unrelated to astronomy. Examination of the job histories and experiences of this cohort gives us crucial, realistic information on the present-day job market and prospects for professional success for new Ph.D.'s in astronomy. This is extremely important at a time when the American Astronomical Society and the profession at large is re-examining the effectiveness and goals of current graduate programs in astronomy. I report here results from a survey of this large cohort of recent graduates, including such information as the average number of postdocs held, and average number of years between receiving the Ph.D. and finding a permanent position in astronomy.

    Faults and joints are conduits for ground-water flow and targets for horizontal drilling in the petroleum industry. Spacing and size distribution are rarely predicted accurately by current structural models or documented adequately by conventional borehole or outcrop samples. Tunnel excavations present opportunities to measure fracture attributes in continuous subsurface exposures. These fracture measurements ran be used to improve structural models, guide interpretation of conventional borehole and outcrop data, and geostatistically quantify spatial and spacing characteristics for comparison to outcrop data or for generating distributions of fracture for numerical flow and transport modeling. Structure maps of over 9 mi of nearly continuous tunnel excavations in Austin Chalk at the Superconducting Super Collider (SSC) site in Ellis County, Texas, provide a unique database of fault and joint populations for geostatistical analysis. Observationally, small faults (<10 ft. throw) occur in clusters or swarms that have as many as 24 faults, fault swarms are as much as 2,000 ft. wide and appear to be on average 1,000 ft. apart, and joints are in swarms spaced 500 to more than 2l,000 ft. apart. Semi-variograms show varying degrees of spatial correlation. These variograms have structured sills that correlate directly to highs and lows in fracture frequency observed in the tunnel. Semi-variograms generated with respect to fracture spacing and number also have structured sills, but tend to not show any near-field correlation. The distribution of fault spacing can be described with a negative exponential, which suggests a random distribution. However, there is clearly some structure and clustering in the spacing data as shown by running average and variograms, which implies that a number of different methods should be utilized to characterize fracture spacing.

    The U.S. Geological Survey, in cooperation with the San Antonio Water System, developed a geodatabase of geologic and hydrogeologic information for selected wells penetrating the Austin Group in central Bexar County, Texas. The Austin Group functions as an upper confining unit to the Edwards aquifer and is the thickest and most permeable of the Edwards aquifer confining units. The geologic and hydrogeologic information pertains to a 377-square-mile study area that encompasses central Bexar County. Data were compiled primarily from drillers' and borehole geophysical logs from federal, State, and local agencies and published reports. Austin Group characteristics compiled for 523 unique wells are documented (if known), including year drilled, well depth, altitude of top and base of the Austin Group, and thickness of the Austin Group.

  6. Simulation of a two-pollutant, two-season pollution offset system for the Colorado River of Texas below Austin

    1992-05-01

    A pollution offset system is a discharge permit system in which transfers are made subject to a restriction that no violations of water quality standards occur at any location. Simulation of a pollution offset system with seasonal variation and multiple pollutants allows for comparison of the savings possible from these design features. A simulation model (Qual-TX) developed by the Texas Water Commission is applied to a case study region near Austin, Texas, yielding impact coefficients for an economic optimization model without investment whose least cost solution represents the theoretical equilibrium of a pollution offset system. The optimization model finds short-run savings of 17.5% for a pollution offset system, as compared to a command and control policy that would also achieve the dissolved oxygen standard. Seasonal variation in permit design produces minimal effects; virtually all savings come from allowing pollution offsets for the two different pollutants.

    Over the period of this grant (1986-92), 23 graduate students were supported by the Center and received education and training in hypersonics through MS and Ph.D. programs. An additional 8 Ph.D. candidates and 2 MS candidates, with their own fellowship support, were attracted to The University of Texas and were recruited into the hypersonics program because of the Center. Their research, supervised by the 10 faculty involved in the Center, resulted in approximately 50 publications and presentations in journals and at national and international technical conferences. To provide broad-based training, a new hypersonics curriculum was created, enabling students to take 8 core classes in theoretical, computational, and experimental hypersonics, and other option classes over a two to four semester period. The Center also developed an active continuing education program. The Hypersonics Short Course was taught 3 times, twice in the USA and once in Europe. Approximately 300 persons were attracted to hear lectures by more than 25 of the leading experts in the field. In addition, a hypersonic aerodynamics short course was offered through AIAA, as well as short courses on computational fluid dynamics (CFD) and advanced CFD. The existence of the Center also enabled faculty to leverage a substantial volume of additional funds from other agencies, for research and graduate student training. Overall, this was a highly successful and highly visible program.

  14. Effects of runoff controls on the quantity and quality of urban runoff at two locations in Austin, Texas

    1987-01-01

    Rapid urban development in the Austin metropolitan area, Texas, is causing concern about increasing peak discharges from stream runoff and the degradation of the quality of water in receiving streams, lakes, and aquifers. In an attempt to reduce peak discharges and improve water quality, runoff controls are being required in certain watersheds. This report summarizes the precipitation, streamflow, and water quality data collected from September 1982 to September 1984 upstream and downstream from runoff controls at two locations, and presents the effects of these runoff controls on streamflow and the quality of runoff water. The runoff controls at the two locations are a detention and filtering pond near Barton Creek Square Shopping Center, a large shopping center located southwest of downtown Austin, and a grass-covered swale control in the Alta Vista Planned Unit Development, a multiple-family housing area. Data indicate that as a result of the Barton Creek Square Shopping Center detention and filtering pond, peak discharges were reduced and peak concentration and loads of most of the analyzed constituents were reduced. However, the grass-covered swale control had little effect on reducing the peak discharges and peak concentrations at the Alta Vista Planned Unit Development. (USGS)

    Petro-Hunt Corp. used a unique horizontal-well design to optimize development of an irregularly shaped lease in the Austin chalk formation in Texas. Two medium-radius horizontal bores were drilled in opposite directions from one vertical hole to maximize horizontal displacement in the lease. Underbalanced drilling techniques were used to prevent formation damage. The well design resulted in a significant cost savings per horizontal foot compared with 24 offset wells that the operator drilled. This paper reviews well planning and drilling and emphasizes techniques used to intersect thin horizontal targets and to initiate the second horizontal bore. Production results and drilling economics are discussed briefly, and ideas on future dual-horizontal-well applications are presented.

  17. PAH Concentrations Decline Following 2006 Ban on Coal-Tar-Based Pavement Sealants in Austin, Texas

    Van Metre, P. C.; Mahler, B. J.

    2013-12-01

    Recent studies have concluded that coal-tar-based pavement sealants (CT sealants) are a major source of polycyclic aromatic hydrocarbons (PAHs) in non-industrial urban settings in the United States. In 2006, Austin, TX, became the first jurisdiction in the U.S. to ban the use of CT sealants. We evaluated PAH concentrations following the ban by analyzing sediment cores collected from Lady Bird Lake in 2012; Lady Bird Lake impounds the Colorado River in central Austin and receives runoff from much of the greater Austin area. The mean sum concentration of the 16 U.S. Environmental Protection Agency Priority Pollutant PAHs (∑PAH16) in one of two 2012 sediment cores analyzed for PAHs declined 75% from before 2006 (mean of 4 samples=8,090 μg kg-1) to 2012 (mean of 2 samples=2,030 μg kg-1), reversing a 40-year (1959-1999) upward trend in PAH concentrations that was previously documented. The downward trend in PAH concentrations in the seven uppermost 1 cm sampling intervals in the first 2012 core was statistically significant (r=0.93, p-value=0.002). Post-2008 PAH trends in the second 2012 core were similar (significant downward trend in the six uppermost 1 cm sampling intervals and mean 2012 ∑PAH16 of 2,390 μg kg-1); however, pre-2007 sediment did not appear to have been preserved in this core likely because of the effects of flooding on sediment deposition and mixing at this site--the largest flood on the Colorado River in Austin in 20 years was in 2007. On the basis of a comparison of lake-sediment PAH profiles to 22 PAH source profiles, the PAH loading to lake sediment continues to be dominated by CT sealants. The continued dominance of proportional PAH loading by CT sealants in spite of decreased concentrations since 2006 might be because legacy CT sealant and contaminated soils and sediments continue to yield PAHs to runoff. A previous study using source-receptor modeling concluded that CT sealants were the largest PAH source to 40 urban lakes studied in the

  19. Pressure solution and microfracturing in primary oil migration, Upper Cretaceous Austin Chalk, Texas Gulf Coast

    1996-09-01

    The Upper Cretaceous Austin Chalk is a well known source rock and fractured reservoir in the Gulf Coast. Production is mainly from tectonic fractures, and the mechanism by which oil migrated from the matrix into the fractures is poorly understood. Microfracturing due to oil generation offers a possible explanation for the mechanism of the primary migration of oil in the Austin Chalk. Petrographic study shows that the major components of the primary migration system are the solution seams and the associated microfractures. Pressure solution is manifest as centimeter to millimeter-scale solution seams and smaller microseams. The solution seams are composites formed by the superposition of the smaller microseams. A significant amount of organic matter was concentrated in the seams along with other insoluble residue. Swarms of horizontal microfractures, many of them filled with calcite and other residue, are associated with the seams. Vertical, tectonic fractures that constitute the reservoir porosity, intersect the solution seams. Pressure solution concentrated organic matter within the solution seams and oil was generated there. It is postulated that the accompanying increase in fluid volume raised the pore pressures and fractured the rock. The newly created microfractures were avenues for migration of fluids from the seams, perhaps by microfracture propagation.

  1. Career Outcomes for Astronomy Ph.D. Graduates of the University of Texas at Austin: The Next Generation

    NASA Astrophysics Data System (ADS)

    Dinerstein, Harriet L.

    2011-01-01

    Sixteen years ago I conducted a survey of the career trajectories and outcomes of 78 individuals who earned Ph.D.s from the Department of Astronomy at the University of Texas at Austin during the period 1984-1995 (Dinerstein, H. 1996, AAS, 189.0501). In the current poster I extend these statistics up to the present, adding 68 Ph.D. recipients from 1996-2010. This is a sufficiently large sample to search for secular trends such as possible changes in duration of the postdoctoral stage, redistribution of demographics among different kinds of long-term positions, and the emergence of new categories of astronomy-related employment. The picture is less discouraging than one might expect. As of 2010, about 75% of the Texas graduates 7 - 14 years past the Ph.D. are still doing astronomy, and most of those in non-astronomical careers left the field by choice (and often have had considerable success in their alternate careers). Of those 6 years or less past the Ph.D., 50% were in postdoctoral positions and less than 10% had left astronomy. Recent reconsiderations of the employment market (Metcalfe, T.S. 2008, PASP, 120, 229; Seth, A. 2009, Astro2010: The Astronomy and Astrophysics Decadal Survey, Position Paper No. 51) make the point that a typical astronomer who ultimately achieves a permanent position will have held two or three prior temporary positions; this was equally true three decades ago. There has been notable growth nationwide in the number of astronomers employed as faculty at small liberal arts colleges and other undergraduate-centered institutions, a trend that to some degree was anticipated by the University of Texas cohort, which included a number of students for whom this was their personal goal. In a world where job certainty is no longer so prevalent, motivated and resourceful astronomers are finding ways to remain active members of our community.

    An economic evaluation has been performed to determine the expected returns on investment for a drilling program in the Giddings, Austin Chalk Gas Field. Using projected production schedules of selected well types from the encountered reserve distribution, computer based cashflow analyses were performed under six hypothesized future scenarios of varying hydrocarbon pricing, demand, taxation, and inflation. For the six future scenarios studied, the Giddings Gas Field drilling program was found to produce a positive, after tax net present value, using 15% as a discount factor. Furthermore, the returns on investment were higher for an independent than for a major producer. Results suggest a drilling program initiated in the near future will prove to be an attractive economic venture.

    The kerogen and bitumen from samples of the Austin Chalk from the subsurface of southeastern Texas were analyzed to determine the origin of the organic matter and the alteration of the kerogen to form petroleum. The effects of mineral composition on the rate of alteration and on the composition of hydrocarbons generated was examined. The source-rock potential and the processes of migration and reservoiring in the chalk are considered.

    Flunitrazepam (Rohypnol) is a benzodiazepine sedative-hypnotic that has generated significant media attention in the United States because of its abuse and its association with "date rape." A field investigation was conducted in south Texas to ascertain the nature and consequences of the abuse of flunitrazepam. In semistructured interviews, 66 subjects identified as flunitrazepam users were asked about their use of alcohol and other drugs and their sexual behaviors. Many subjects identified the drugs they had used as "roches" and gave descriptions of tablets of other benzodiazepines that were not consistent with flunitrazepam. Almost all subjects used other drugs, primarily alcohol and marijuana. Adverse consequences included amnesia, discoordination, automobile accidents, sexual assault, and respiratory depression or arrest. A significant proportion of the subjects reported that continued use was unappealing to them. The abuse of sedative-hypnotics in southeast Texas involves several benzodiazepines and is not limited to flunitrazepam. PMID:8811586

    Four sections were measured along a 1/4 mi length of Little Walnut Creek. The first section was 165 ft north of the US. 290 bridge while the fourth was 1/4 mi upstream. Structurally, the stream follows the fault in this section. Small faults can be found perpendicular to the primary fault and apparently account not only for minor variation in local dip (8{degrees}SE, parallel to 5{degrees}NW) but also for the placement of at least one tributary. Megainvertebrate exoskeletons were found to have been inhabited by incrusting bryozoans, boring bryozoans, and sponges. These fossils were found on both interior and exterior surfaces of Exogyra laeviuscula E tigrina, and interior surfaces of Inoceramus. A low-energy environment allowed exposure of megainvertebrate exoskeletons after death but also prevented fracturing. Low siltation rates also extended exoskeleton availability after organismic death. The nonboring bryozoans are cheilostomes and at least one species, Pyripora, has been described from the Kansas Cretaceous as well as European Cretaceous sites. The boring bryozoans are primarily represented by Terebripora sp. In conclusion, this section of Dessau Chalk Formation, Upper Austin Group, was mostly a low-energy environment, shallow, limy mud platform. This substrate was probably not stable enough for bryozoan colonization as unattached colonies have not been found in sediments. Therefore, bryozoan substrates were limited to living and dead Exogyra sp. and dead Inoceramus sp. exoskeletons.

  6. Estimating organic maturity from well logs, Upper Cretaceous Austin Chalk, Texas Gulf coast

    1990-09-01

    The Austin Chalk is both a source rock for oil and a fractured reservoir, and the evaluation of its organic maturity from well logs could be an aid to exploration and production. Geochemical measurements have shown three zones of organic maturity for source materials: (1) an immature zone to depths of 6,000 ft, (2) a peak-generation and accumulation zone from 6,000 to 6,500 ft, and (3) a mature, expulsion and migration zone below 6,500 ft. The response of common well logs identifies these zones. True resistivity (R{sub t}) is low in the immature zone, increases to a maximum in the peak-generation zone, and decreases to intermediate values in the expulsion zone. Density and neutron porosities are different in the immature zone but are nearly equal in the peak generation and expulsion zones. Correlations with conventional core analyses indicate that R{sub t} values between 9 and 40 ohm-m in the expulsion zone reflect a moveable oil saturation of 10 to 20% in the rock matrix. The moveable saturation provides oil from the matrix to fractures and is essential for sustained oil production. Therefore, the evaluation of moveable oil from well logs could be important in exploration.

  7. Application of thematic mapper imagery to oil exploration in Austin Chalk, Central Gulf Coast basin, Texas

    SciTech Connect

    Reid, W.M.

    1988-01-01

    One of the newest major oil plays in the Gulf Coast basin, the Austin Chalk reportedly produces in three belts: an updip belt, where production is from fractured chalk in structurally high positions along faults above 7,000 ft; a shallow downdip belt, where the chalk is uniformly saturated with oil from 7,000 to 9,000 ft; and a deeper downdip belt saturated with gas and condensate below 9,000 ft. The updip fields usually occur on the southeastern, upthrown side of the Luling, Mexia, and Charlotte fault zones. Production is from fractures that connect the relatively sparse matrix pores with more permeable fracture systems. The fractures resulted from regional extensional stress during the opening of the Gulf Coast basin on the divergent margin of the North American plate during the Laramide orogeny. The fractures are more common in the more brittle chalk than in the overlying Navarro and underlying Eagle Ford shales, which are less brittle. The oil in the updip traps in the chalk may have been generated in place downdip, and migrated updip along the extension fractures into the updip traps during or after the Laramide orogeny.

This result is unchanged when the preliminary temperature structure derived by the Voyager Radio Occultation Experiment is used instead of Appleby's model c. Out of the six Pluto-Charon mutual events observed this year, data were obtained on four.

    NSF GK-12 Fellows at The University of Texas at Austin Institute for Geophysics (UTIG) actively contribute to K-12 education by linking K-12 students and teachers to research scientists and recent discoveries, and by developing hands-on learning activities designed primarily for secondary school learning environments. The excitement of the new Integrated Ocean Drilling Program (IODP), an international research program that explores the history and structure of the Earth by studying the sediments and rocks beneath the seafloor, has provided UTIG's GK-12 Fellows with an incentive to develop new, and revise existing, inquiry-based learning activities based on the science, technology and/or data of scientific ocean drilling. These activities, grouped into a curriculum module, address the mechanics of collecting cores, fossil identification and age relationships within a core, and the interpretation of geophysical logs. They expose teachers and students to the exciting science and advanced technology of the IODP and the achievements of the Ocean Drilling Program, which preceded IODP. UTIG scientists active in the IODP guided the development of the module's science content. The module activities are aligned with U.S. educational standards, but could be adapted for use in other countries that participate in the IODP. Where this isn't possible, they can serve as an example of educational curriculum materials that underscore the vital nature of international collaboration.

    Rapid urbanization has accelerated land use and land cover changes, and generated the urban heat island effect (UHI). Previous studies have reported positive effects of neighborhood landscapes on mitigating urban surface temperatures. However, the influence of neighborhood landscape spatial patterns on enhancing cooling effects has not yet been fully investigated. The main objective of this study was to assess the relationships between neighborhood landscape spatial patterns and land surface temperatures (LST) by using multi-regression models considering spatial autocorrelation issues. To measure the influence of neighborhood landscape spatial patterns on LST, this study analyzed neighborhood environments of 15,862 single-family houses in Austin, Texas, USA. Using aerial photos, geographic information systems (GIS), and remote sensing, FRAGSTATS was employed to calculate values of several landscape indices used to measure neighborhood landscape spatial patterns. After controlling for the spatial autocorrelation effect, results showed that larger and better-connected landscape spatial patterns were positively correlated with lower LST values in neighborhoods, while more fragmented and isolated neighborhood landscape patterns were negatively related to the reduction of LST.

  12. Role of shale thickness on vertical connectivity of fractures: application of crack-bridging theory to the Austin Chalk, Texas

    NASA Astrophysics Data System (ADS)

    Rijken, Peggy; Cooke, Michele L.

    2001-07-01

    Contrasting material properties of alternating chalk and shale layers control vertical connectivity of fractures. Our field observations within the Austin Chalk, Texas indicate that: (1) the majority of vertical fractures occur in chalk layers and abut against contacts with shale layers, (2) thicker shale layers have greater resistance to fracture propagation than thinner shale layers. From these observations we hypothesize both the resistance of shale to fracturing and the thickness of shale layers may inhibit fracture propagation across the shale and into the next chalk layer. We model crack propagation within a three-layered system (brittle chalk:fracture resistant shale:brittle chalk). The modeled crack extends across the shale, but closing tractions applied to the crack segment within the shale layer simulate resistance of shale to fracturing. The crack-tip lies a short distance within the unfractured chalk layer simulating a coplanar flaw with potential to propagate. If the stress intensity factor at the flaw exceeds the chalk fracture toughness, the crack propagates, thereby bridging and eventually rupturing the shale layer. For any chalk thickness, there is a critical shale thickness above which fractures cross the shale layer and below which fractures arrest at shale. Finite Element Method (FEM) analysis evaluates the influence of shale ductility within the chalk: shale: chalk system. Although remote and fluid pressure driven fractures produce identical stress intensity factors in elastic chalk/shale systems, lower driving stresses are required to propagate fluid pressure driven fractures through a system ductile shale layers than fractures under remote tension.

    Concentrations, loads, and yields of particle-associated (hydrophobic) contaminants (PACs) in urban runoff in creeks in Austin, Texas, were characterized using an innovative approach: large-volume suspended-sediment sampling. This approach isolates suspended sediment from the water column in quantities sufficient for direct chemical analysis of PACs. During 1999-2004, samples were collected after selected rain events from each of five stream sites and Barton Springs for a study by the U.S. Geological Survey, in cooperation with the City of Austin. Sediment isolated from composited samples was analyzed for major elements, metals, organochlorine compounds, and polycyclic aromatic hydrocarbons (PAHs). In addition, at the Shoal Creek and Boggy Creek sites, individual samples for some events were analyzed to investigate within-event variation in sediment chemistry. Organochlorine compounds detected in suspended sediment included chlordane, dieldrin, DDD, DDE, DDT, and polychlorinated biphenyls (PCBs). Concentrations of PACs varied widely both within and between sites, with higher concentrations at the more urban sites and multiple nondetections at the least-urban sites. Within-site variation for metals and PAHs was smaller than between-site variation, and concentrations and yields of these and the organochlorine compounds correlated positively to the percentage of urban land use in the watershed. Loads of most PACs tested correlated significantly with suspended-sediment loads. Concentrations of most PACs correlated strongly with three measures of urban land use. Variation in suspended-sediment chemistry during runoff events was investigated at the Shoal and Boggy Creek sites. Five of the eight metals analyzed, dieldrin, chlordane, PCBs, and PAHs were detected at the highest concentrations in the first sample collected at the Shoal Creek site, a first-flush effect, but not at the Boggy Creek site.

    2009-10-01

    The Summer Nuclear Engineering Institute (SNEI) at the University of Texas is a four week course that provides an opportunity for undergraduates to experience the field of nuclear engineering. This experience is especially important if you are a sophomore or junior and are not majoring in nuclear engineering as an undergrad, but would like to explore what nuclear engineering is like. Students will study fundamental nuclear engineering concepts, gain hands-on experience at UT's research reactor and receive six transferrable college credits. The SNEI program was first held in July of 2009, and will be held once again in the summer of 2010; it is funded by the U.S. Nuclear Regulatory Commission Nuclear Education Grant Program which covers housing, meal plan, a travel and textbook allowance and a 1000 stipend.

  17. Quantity and quality of runoff reduction and recharge enhancement from constructed rain gardens and vegetated retention ponds in Austin, Texas

    Rain gardens and retention ponds are intended to reduce storm water and pollutant runoff to rivers and streams, rain gardens by enhancing infiltration and retention ponds by promoting evaporation. The City of Austin, Texas is actively investing money and time into these storm water management solutions, but there are no data comparing their effectiveness. In particular, comparisons of rain gardens against control plots and new wetland-vegetated retention pond designs against traditional grassy pond designs are lacking. This study quantifies the quantity and quality of storm runoff to and from five sites: three engineered sites, two rain gardens receiving direct runoff from the same residential roof and a planted retention pond receiving municipal parking lot runoff, and two control sites, a mulched residential lawn receiving direct roof runoff and a grassy municipal retention pond receiving parking lot runoff. A locally installed rain gauge monitors precipitation rates and we collect and analyze rainwater chemistry. Each site is instrumented with bottles to collect direct runoff samples and suction lysimeters within and below the root zone, at 10 cm and 40 cm depth, from which to collect soil water. Soil moisture sensors at 5 cm, 25 cm, and 50 cm depth are used to monitor changes in soil moisture profiles over time. Evapotranspiration rates were determined using local meteorological data and stomatal conductance measurements at the sites. Infiltrometer tests, soil characterizations, and vegetation surveys were also conducted at each site. The soil at the rain gardens are highly mixed with pebbles at the top and become a more uniform soil towards the bottom of the root zone. This differs from the control site where the soil is uniform except for the thin layer of wood chips at the surface. The water samples were analyzed for pH, dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and cations (incl. cadmium, iron, zinc, and lead) and anions (incl

    Faculty and staff at the University of Texas at Austin collected solar resource measurements at their campus using equipment on loan from the National Renewable Energy Laboratory. The equipment was used to train students on the operation and maintenance of solar radiometers and was returned to NREL's Solar Radiation Research Laboratory upon completion of the CRADA. The resulting data augment the solar resource climatology information required for solar resource characterizations in the U.S. The cooperative agreement was also consistent with NREL's goal of developing an educated workforce to advance renewable energy technologies.

  19. Occurrence of oil in the Austin Chalk at Van field, Van Zandt County, Texas: A unique geologic setting

    1990-09-01

    The Austin Chalk is buried to a depth of only 2,100-2,500 ft and has retained primary microporosity unlike the typical deep fractured chalk reservoirs. The Van structure is a complexly faulted domal anticline created by salt intrusion and is approximately 2,000 ft higher than surrounding structures in the area. A major northwest-dipping fault acts as the primary trapping mechanism. The field has produced 0.5 billion BO from thick Woodbine sands since its discovery in 1929. Occurrence of oil in the Austin Chalk has been known since the field discovery, but prior completions were low rate oil producers. Recent development of a large fracture stimulation technique has resulted in increased production rates of up to 300 BOPD. The Austin Chalk reservoir limits were determined by isopaching feet of minimum productive resistivity having porosity above a cutoff value. The resistivity/porosity isopach showed a direct correlation between Austin Chalk productivity and the Austin Chalk structure and faulting pattern. Structural evidence along with oil typing indicate that the oil in the Austin Chalk has migrated upward along fault planes and through fault juxtaposition from the Woodbine sands 200 ft below the Austin Chalk. Thin-section and scanning electron microscopy work performed on conventional cores showed that the Van Austin Chalk formation is a very fine grained limestone composed primarily of coccoliths. Various amounts of detrital illite clay are present in the coccolith matrix. All effective porosity is micro-intergranular and ranges from 15 to 35%. Based on the core analyses, the main porosity reducing agent and therefore control on reservoir quality is the amount of detrital clay present filling the micropores. Permeability is very low with values ranging from 0.01 to 1.5 md. There is no evidence of significant natural fractures in the core. Artificial fractures are therefore required to create the permeability needed to sustain commercial production rates.

    2006-01-01

    From 2003 to 2005, the U.S. Geological Survey, in cooperation with the Texas Commission on Environmental Quality, collected and analyzed water samples from the four springs (orifices) of Barton Springs in Austin, Texas (Upper, Main, Eliza, and Old Mill Springs), with the objective of characterizing water quality. Barton Springs is the major discharge point for the Barton Springs segment of the Edwards aquifer. A three-pronged sampling approach was used: physicochemical properties (including specific conductance and turbidity) were measured continuously; samples were collected from the four springs routinely every 2 weeks (during August-September 2003) to 3 weeks (during June 2004-June 2005) and analyzed for some or all major ions, nutrients, trace elements, soluble pesticides, and volatile organic compounds; and samples were collected from the four springs at more closely spaced intervals during the 2 weeks following two storms and analyzed for the same suite of constituents. Following the two storms, samples also were collected from five of the six major streams that provide recharge to Barton Springs. Spring discharge during both sample collection periods was above average (60 cubic feet per second or greater). Barton Springs was found to be affected by persistent low concentrations of atrazine (an herbicide), chloroform (a drinking-water disinfection by-product), and tetrachloroethene (a solvent). Increased recharge from the major recharging streams resulted in increased calcium, sulfate, atrazine, simazine, and tetrachloroethene concentrations and decreased concentrations of most other major ions, nitrate, and chloroform at one or more of the springs. These changes in concentration demonstrate the influence of water quality in recharging streams on water quality at the springs even during non-stormflow conditions. The geochemical compositions of the four springs indicate that Upper Spring is more contaminated and is influenced by a contributing flow path that

    1981-08-01

    The Austin Chalk is an impure onshore chalk that was deposited on a ramp marginal to the Gulf of Mexico during the Late Cretaceous. Basinal chalks are organic rich, commonly containing 0.5-5.0% amorphous, sapropelic kerogen derived from marine organic matter with only trace amounts of terrestial kerogen. Less organic matter was deposited and perserved in oxygenated shallow water, and fresh-water diagenesis oxidized the organic matter on outcrop. In each sample, the kerogen is concentrated in microstylolites, with organic fluids segregated in micropores in the chalk.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Texas Army National Guard (ARNG) property in Austin, Texas. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing, preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining, site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the Bee Caves Armory property, the requirements of the Department of Defense Installation Restoration Program. Of concern is the potential for hazardous waste to be present on the property as a result of the former Nike Missile Base operations or in the form of original construction materials. Environmentally sensitive operations associated with the property from that period include (1) underground fuel storage, (2) hazardous materials storage/use, (3) disposal of hazardous waste and (4) release of hazardous waste water.

    The US DOE initiated this project to evaluate the performance of an air conditioner retrofit program in Austin, Texas. The City's Austin's Resource Management Department pursued this project to quantify the retrofit effect of replacing low-efficiency air conditioners with high-efficiency air conditioners in single-family detached homes. If successfully implemented, this retrofit program could help defer construction of a new power plant which is a major goal of this department. The project compares data collected from 12 houses during two cooling seasons under pre-retrofit and then post-retrofit air conditioner units. The existing low-efficiency air conditioners were monitored during the 1987 cooling season, replaced during the 1987--88 heating season with new, smaller sized, high-efficiency units, and then monitored again during the 1988 cooling season. Results indicated that the air conditioner retrofits reduce the annual air conditioner electric consumption and peak electric demand by an average of 38%. When normalized to the nominal capacity of the air conditioner, average demand savings were 1.12 W/ft{sup 2} and estimated annual energy savings were 1.419 kWh/ft{sup 2}. Individual air conditioner power requirements were found to be a well defined function of outdoor temperature as expected. In the absence of detailed data, estimates of the peak demand reductions of new air conditioners can be made from the manufacturer's specifications. Air conditioner energy consumption proved to be strongly linear as a function of the outdoor temperature as expected when taken as an aggregate. No noticeable differences in the diversity factor of the air conditioner usage were found. Analysis of the retrofit effect using PRISM yields estimates of the reduction in normalized annual consumption (NAC) and annual cooling consumption of 12% and 30%. 2 refs., 11 figs., 17 tabs.

  9. Concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) and Major and Trace Elements in Simulated Rainfall Runoff From Parking Lots, Austin, Texas, 2003

    2004-01-01

    Samples of creek bed sediment collected near seal-coated parking lots in Austin, Texas, by the City of Austin during 2001?02 had unusually elevated concentrations of polycyclic aromatic hydrocarbons (PAHs). To investigate the possibility that PAHs from seal-coated parking lots might be transported to urban creeks, the U.S. Geological Survey, in cooperation with the City of Austin, sampled runoff and scrapings from four test plots and 13 urban parking lots. The surfaces sampled comprise coal-tar-emulsion-sealed, asphalt-emulsion-sealed, unsealed asphalt, and unsealed concrete. Particulates and filtered water in runoff and surface scrapings were analyzed for PAHs. In addition, particulates in runoff were analyzed for major and trace elements. Samples of all three media from coal-tar-sealed parking lots had concentrations of PAHs higher than those from any other types of surface. The average total PAH concentrations in particulates in runoff from parking lots in use were 3,500,000, 620,000, and 54,000 micrograms per kilogram from coal-tar-sealed, asphalt-sealed, and unsealed (asphalt and concrete combined) lots, respectively. The probable effect concentration sediment quality guideline is 22,800 micrograms per kilogram. The average total PAH (sum of detected PAHs) concentration in filtered water from parking lots in use was 8.6 micrograms per liter for coal-tar-sealed lots; the one sample analyzed from an asphalt-sealed lot had a concentration of 5.1 micrograms per liter and the one sample analyzed from an unsealed asphalt lot was 0.24 microgram per liter. The average total PAH concentration in scrapings was 23,000,000, 820,000, and 14,000 micrograms per kilogram from coal-tar-sealed, asphalt-sealed, and unsealed asphalt lots, respectively. Concentrations were similar for runoff and scrapings from the test plots. Concentrations of lead and zinc in particulates in runoff frequently exceeded the probable effect concentrations, but trace element concentrations showed no

  10. Investigation of Hyporheic Thermal Flux and Downstream Attenuation Driven by Hydropeaking in the Colorado River, Austin, Texas

    2015-12-01

    Thermal flux related to regulated river hydropeaking has been extensively researched at the single-study site scale, but little work has been done quantifying the downstream attenuation of a single regulated flood pulse at multiple sites. In order to better understand this flood pulse attenuation we instrumented four sites with temperature probes along a 91 km stretch of the Colorado River downstream of longhorn dam, Austin, TX. Piezometer transects perpendicular to the river at each site were instrumented with HOBO thermistors over a 1.4m screened interval within the saturated zone at 20cm spacing. As flood pulses are attenuated downstream, temperature gradients and distance of lateral temperature pulse penetration into the bank are hypothesized to decrease. The data collected in this investigation will test this hypothesis by providing 2D temperature cross-sections along an attenuating flood pulse, providing detailed spatial data on temperature gradients adjacent to the river.

  11. PAH concentrations in lake sediment decline following ban on coal-tar-based pavement sealants in Austin, Texas

    Van Metre, Peter C.; Mahler, Barbara J.

    2013-01-01

    Recent studies have concluded that coal-tar-based pavement sealants are a major source of polycyclic aromatic hydrocarbons (PAHs) in urban settings in large parts of the United States. In 2006, Austin, TX, became the first jurisdiction in the U.S. to ban the use of coal-tar sealants. We evaluated the effect of Austin’s ban by analyzing PAHs in sediment cores and bottom-sediment samples collected in 1998, 2000, 2001, 2012, and 2014 from Lady Bird Lake, the principal receiving water body for Austin urban runoff. The sum concentration of the 16 EPA Priority Pollutant PAHs (∑PAH16) in dated core intervals and surficial bottom-sediment samples collected from sites in the lower lake declined about 44% from 1998–2005 to 2006–2014 (means of 7980 and 4500 μg kg–1, respectively), and by 2012–2014, the decline was about 58% (mean of 3320 μg kg–1). Concentrations of ∑PAH16 in bottom sediment from two of three mid-lake sites decreased by about 71 and 35% from 2001 to 2014. Concentrations at a third site increased by about 14% from 2001 to 2014. The decreases since 2006 reverse a 40-year (1959–1998) upward trend. Despite declines in PAH concentrations, PAH profiles and source-receptor modeling results indicate that coal-tar sealants remain the largest PAH source to the lake, implying that PAH concentrations likely will continue to decline as stocks of previously applied sealant gradually become depleted.

    Twenty-two bottom-sediment samples were collected from Town Lake in Austin, Texas, in 1991 and 1992 and analyzed for chlorinated insecticides by a reconnaissance-quality, electron-capture gas chromatography screening method developed by the U.S. Geological Survey (USGS). Four different chlorinated insecticides (aldrin, chlordane, dieldrin, and p,p'-DDT) and two degradation products of p,p'-DDT (p,p'-DDD and p,p'-DDE) were detected in these samples. The most significant insecticides detected were chlordane, which was detected in 20 of the 22 samples at concentrations that ranged from 26 to 140 micrograms per kilogram, and p,p'-DDT, which was detected in all 22 samples at concen- trations that ranged from 5 to 40 micrograms per kilogram. Degradation products of p,p'-DDT were detected in all 22 samples. Concentrations of p,p'-DDD ranged from not detected to 117 micrograms per kilogram and for p,p'-DDE from 9 to 97 micrograms per kilogram. Of the 22 samples collected, 15 also were analyzed by the standard USGS laboratory analytical method for chlorinated insecticides to determine the comparability of the two methods. Correlation coefficients were calculated for chlordane (0.8662), p,p'-DDT (0.6393), p,p'-DDD (0.9401), p,p'-DDE (0.8595), and dieldrin (0.3819). A paired sign test at the 95 percent confidence level showed no significant difference between the screening method and laboratory analytical method for all detected insecticides except aldrin. P-values were calculated from the data for chlordane (l.0000), p,p'-DDT (0.1796), p,p'-DDD (l,0000), p,p'-DDE (0.1796), and dieldrin (0.2891).

    1991-04-01

    Horizontal drilling in the Cretaceous Austin chalk trend of South Texas continues to set a fast pace. The Texas Railroad Commission has issued nearly 900 permits to drill horizontal wells in the Pearsall field area alone from 1984 through February 1991. TRC issued 1,485 permits for horizontal wells statewide during that period, including 1,285 since Jan. 1, 1990. Statewide, operators have reported completion of 685 horizontal wells. That includes 472 in Pearsall field, where TRC has issued 882 permits, and 121 in Giddings field, where 305 permits have been issued. Frio County, site of Pearsall field, led Texas counties with 494 permits and 278 horizontal completions. Oil drilling and reentry work is under way in many areas, and horizontal Austin chalk gas/condensate completions have been reported in Dimmit and Burleson counties.

    1983-01-01

    Development drilling in the Austin chalk primarily is centered in a 5-county area between Giddings and Caldwell, Texas. Latest statistics indicate that 182 producers currently are operating in the area with a projected total production of approx. 125,000 bopd and 400 MMcfd. Cumulative oil production stands at nearly 75 million bbl. Surface production facilities include pumping units, production batteries, compressor stations, processing plants, and pipeline gathering systems for both oil and gas. An overview and a discussion of these facilities, as they pertain to the Giddings field and the Austin Chalk, are presented.

    This study presents design completion techniques being used to stimulate the Austin Chalk Formation in the Giddings field and Gonzales County, Texas. As background information, a history of the Giddings field and development of the Austin Chalk is discussed. The main purpose is to consider factors affecting fracture treatment design, including fracture height, pump rates, types of fracturing fluids, proppant concentrations, and leak-off controls. This is to insure effective and successful stimulation treatment. Possible alternative design considerations for future fracture treatments also are discussed.

  15. Favorable prices justify Austin Chalk plants

    SciTech Connect

    Mickey, V.

    1981-03-01

    The elements of economics required to justify new natural gas processing plants seem to come together in the Austin Chalk trend of south-central Texas. The Mapco pipeline which originates in the western overthrust belt and carries natural gas liquids to Mont Belvieu, Texas, provides a market for the liquids. With 110 rigs drilling in a 4-county area of the Chalk (Burleson, Lee, Fayette, and Brazos), natural gas reserves are being proven adequate to justify the many new plants being placed in the area. Natural gas liquids prices, which historically are closely correlated with crude oil prices, are reflecting the impact of partial decontrol of those prices. Improvements in natural gas processing technology allow for more energy-efficient plants with more control over the liquids products produced. The result is a hotbed of natural gas processing activity in the Austin Chalk trend.

    Wells drilled in the Central Texas Austin Chalk formation tend to deplete rapidly, with production rates declining to 10 bopd or less within months of completion. According to the authors, these wells can often be restored with a dendritic fracturing treatment. Production from 50 conventionally fraced chalk wells averaged only 6 bopd. After dendritic fracturing, average output increased to 61.2 bopd. Similar results were obtained from wells not previously treated.

This area's difficulties have included high pressure gas, lost circulation in low pressure zones, varying content of producing formations, varying grades and qualities of production in the same producing zones, and faulting. The potential for severe kicking is always present, and casing failures are common. Procedures for dealing with the expected kicks, lost circulation, difficult casing jobs, and variable production are described.

  5. Seismic and horizontal drilling unlock Austin Chalk

    SciTech Connect

    1990-09-01

    Giddings is a Texas field whose economic production is totally dependent on the development of natural fracture porosity. Matrix porosities and permeabilities in the Austin Chalk limestone, the primary objective, are incapable of maintaining commercial hydrocarbon production. This paper discusses how fracture identification from seismic data has been used as a successful prospecting tool in the area for over ten years. The advent of horizontal drilling technology now allows the development of multiple seismic fracture indicators in the same wellbore. These indicators often represent unique hydrocarbon accumulations.

    The object of this work is to discuss the most widely used stimulation techniques employed in the Austin Chalk formation in S. Texas. Although this trend has been explored for years and continues to be one of the most active in the country, there remains a difference of opinion over how to effectively stimulate this reservoir. Several schools of thought regarding types of fluids, additives, and general treating techniques are examined. The fracture geometry of various treatments as predicted by pre-treatment computer designs are compared to the parameters obtained from post-frac analysis.

  7. Late Cretaceous (Austin Group) volcanic deposits as a hydrocarbon trap

    SciTech Connect

    Hutchinson, P.J.

    1994-09-01

    A Late Cretaceous submarine igneous extrusion occurs in the subsurface of southwestern Wilson County, Texas. The Coniacian-Santonian-aged (Austin Group) volcanic eruption discharged large volumes of magnetite-rich olivine nephelinite, that upon quenching, formed an extensive nontronitic clay layer. This clay deposit formed a trapping mechanism for hydrocarbons beneath the volcano; production from these features is normally attributed to the shoal-water carbonate facics developed on top of the volcano. The heat energy of the volcano may have thermally matured the calcareous sediments of the Austin Chalk contiguous with the volcano. The normally grayish-colored Austin Chalk in contact with the intrusive portion of the igneous material displays a greenish color suggesting thermal alteration. The overlying nontronite trapped the mobile hydrocarbons, and early emplacement may have preserved some of the original porosity and permeability of the Austin Chalk. Austin Chalk-aged volcanic deposits produce hydrocarbons from stratigraphic traps within the volcanic material, within the porous beachrock, and structurally within overlying sandstones. The intruded Austin Chalk also behaves as a reservoir because the original porosity and permeability is maintained through early emplacement of oil and the overlying volcanic clay prevents vertical migration. Marcefina Creek, discovered in 1980 from an {open_quotes}augen{close_quotes}-shaped seismic signature and an aerial magnetic survey, produces from the fractured chalk beneath the nontronitic clay layer. This field has produced over seven million bbl of oil from over 40 wells from fractured and porous rock beneath the volcano.

  8. Relation of Specific Conductance in Ground Water to Intersection of Flow Paths by Wells, and Associated Major Ion and Nitrate Geochemistry, Barton Springs Segment of the Edwards Aquifer, Austin, Texas, 1978-2003

    Understanding of karst flow systems can be complicated by the presence of solution-enlarged conduits, which can transmit large volumes of water through the aquifer rapidly. If the geochemistry at a well can be related to streamflow or spring discharge (springflow), or both, the relations can indicate the presence of recent recharge in water at the well, which in turn might indicate that the well intersects a conduit (and thus a major flow path). Increasing knowledge of the occurrence and distribution of conduits in the aquifer can contribute to better understanding of aquifer framework and function. To that end, 26 wells in the Barton Springs segment of the Edwards aquifer, Austin, Texas, were investigated for potential intersection with conduits; 26 years of arbitrarily timed specific conductance measurements in the wells were compared to streamflow in five creeks that provide recharge to the aquifer and were compared to aquifer flow conditions as indicated by Barton Springs discharge. A nonparametric statistical test (Spearman's rho) was used to divide the 26 wells into four groups on the basis of correlation of specific conductance of well water to streamflow or spring discharge, or both. Potential relations between conduit intersection by wells and ground-water geochemistry were investigated through analysis of historical major ion and nitrate geochemistry for wells in each of the four groups. Specific conductance at nine wells was negatively correlated with both streamflow and spring discharge, or streamflow only. These correlations were interpreted as evidence of an influx of surface-water recharge during periods of high streamflow and the influence at the wells of water from a large, upgradient part of the aquifer; and further interpreted as indicating that four wells intersect major aquifer flow paths and five wells intersect minor aquifer flow paths (short, tributary conduits). Specific conductance at six wells was positively correlated with spring

    Hutchinson, P.J.

    1994-12-31

    An Upper Cretaceous submarine igneous extrusion occurs in the subsurface of southwestern Wilson County, Texas. The Coniacian-Santonian-aged (Austin Group) volcanic eruption discharged large volumes of magnetite-rich olivine nephelinite that upon quenching formed an extensive nontronitic clay layer. This clay deposit formed a trapping mechanism for hydrocarbon beneath the volcano. Production from volcanic plugs is normally attributed to the shoal-water carbonate facies developed on top of the volcanic, the palagonite tuff ({open_quotes}serpentine{close_quotes}), and overlying sandstones. The heat energy of the volcano may have thermally matured the calcarous sediments of adjacent parts of the Austin Chalk. The normally grayish-colored suggesting thermal alteration. The overlying nontronite trapped mobile hydrocarbons, and this early emplacement of oil may have preserved some of the original porosity and permeability of the Austin Chalk. Austin Chalk-aged volcanic deposits produce hydrocarbons from stratigraphic traps within the volcanic material, within the porous beachrock, and structurally within overlying sandstones. The intruded Austin Chalk also behaves as a reservoir because the original porosity and permeability are maintained by early emplacement of oil and the overlying volcanic clay acts as a seal by preventing vertical migration. Marcelina Creek field, discovered in 1980 from an {open_quotes}augen{close_quotes}-shaped seismic signature and an aerial magnetic survey, produces from the fractured chalk beneath the nontronitic clay layer. This field has produced more than 15 million barrels of oil from more than 60 wells in fractured and porous rock beneath the volcano.

  12. Horizontal drilling in the Austin Chalk: Stratigraphic factors

    Durham, C.O. Jr. ); Bobigian, R.A. )

    1990-05-01

    Horizontal drilling has renewed interest in the Austin chalk in south-central Texas. Large fields on opposite sides of the San Marcos arch Giddings to the northeast and Pearsall to the southwest were active with vertical drilling 10 years ago. Giddings' 4,500 Austin wells produced 209 million BO and 934 bcfg of gas through 1988; Pearsall's 1,440 wells produced 57 million BO and 35 bcfg of gas. Most vertical wells were completed, 20% were economic successes, 40% were marginal, 40% were uneconomic due to uneven areal distribution of near-vertical fractures and small faults, which provide reservoirs in otherwise tight chalk. Horizontal drilling, led by Amoco in Giddings and Oryx in Pearsall, enhances the chances of encountering the fractures by drilling perpendicular to the fracture trend. Horizontal drilling requires preselection of the stratigraphic horizon to be penetrated. One must understand the variable Austin stratigraphy to choose the zone with the most brittle character and best matrix porosity, both reduced by increased clay content. Chalk 130 ft thick on the San Marcos arch thickens to 600 to 800 ft in central Giddings field where middle marl separates lower and upper chalk Northeastward only lower chalk is preserved beneath a post-Austin submarine channel. The Austin thickens to 300-500 ft in Pearsall field where middle member ash beds separate lower and upper chalk inhibiting vertical reservoir communication. Locally, on the Pearsall arch, ash is missing, lower chalk thickens, and upper chalk thins.

  13. Structural stratigraphy of Austin Chalk

    SciTech Connect

    Corbett, K.P.; Friedman, M.

    1983-03-01

    The mechanical behavior (structural stratigraphy) of the Upper Cretaceous Austin Chalk is established from the study of fracture intensity along its outcrop trend from Dallas to San Antonio and westward to Langtry, Texas, and in the subsurface from the study of core and/or fracture identification logs from 39 wells. Three mechanical-stratigraphic units are recognized as: (1) an upper, fractured massive chalk corresponding to the Bid House Chalk Member, (2) a middle, ductile chalk-marl corresponding to the Dessau Chalk and Burditt Marl Members, and (3) a lower, fractured massive chalk corresponding to the Atco Chalk Member. Representative samples from these units were experimentally shortened dry, at 10, 17 34, and 70-MPa confining pressure, 24/sup 0/C (75/sup 0/F), and at 2.5 x 10/sup -4/ s/sup -1/ to determine if the relative mechanical behavior observed at the surface could be extrapolated into the subsurface at different simulated depths of burial. The experimentally determined ductilities do parallel those determined from outcrop and subsurface studies. Through multiple linear regression analyses of strength versus intrinsic rock properties and environmental parameters, it appears that first porosity and then smectite-content are most strongly correlated with strength. For low-porosity specimens (9 to 13.5%) smectite present in amounts as little as 1% by volume has the highest correlation with strength accounting for 83% of its variability. SEM photomicrographs show that the clays are smeared-out along the induced shear fracture surfaces where they are greatly reduced in grain-size. These observations suggest that the smectite acts mechanically as a soft-inclusion, localizing shear failure and correspondingly weakening the material.

    The Texas Center for Health Disparities, a National Institute on Minority Health and Health Disparities Center of Excellence, presents an annual conference to discuss prevention, awareness education and ongoing research about health disparities both in Texas and among the national population. The 2013 Texas Conference on Health Disparities brought together experts, in research, patient care and community outreach, on the “Intersection of Smoking, Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and Cancer”. Smoking, HIV/AIDS and cancer are three individual areas of public health concern, each with its own set of disparities and risk factors based on race, ethnicity, gender, geography and socio-economic status. Disparities among patient populations, in which these issues are found to be comorbid, provide valuable information on goals for patient care. The conference consisted of three sessions addressing “Comorbidities and Treatment”, “Public Health Perspectives”, and “Best Practices”. This article summarizes the basic science, clinical correlates and public health data presented by the speakers. PMID:24227993

  5. Homing in on sweet spots in Cretaceous Austin chalk

    SciTech Connect

    Thomas, G.E. ); Sonnenberg, F.P.

    1993-11-29

    In discussing the nature and causes of fracturing in the Cretaceous Austin chalk of south central Texas, many geologists and operators involved in horizontal drilling of the chalk consider regional rock stress as the probable main cause of the fractures. If Austin chalk fractures are mainly the result of regional extensional stress without localizing factors, then fractured sweet spots are randomly distributed and successful exploration is more or less a matter of luck, usually dependent upon the coincidental placement of a seismic line. But if local, deep-seated structure or basement topography are the main causes of sweet spots, then a successful exploration method would be to first delineate the basement paleo structure or topography and secondly, place a seismic line to confirm the delineated features. Finding localities of maximum fracturing and production would than be based on scientific logic rather than luck. It is the purpose of this article to present the results of an examination of these alternative causes for the Austin chalk fracturing in the hope of determining the most cost effective exploration method for the fractured chalk reservoir.

  6. Fracture detection techniques in the Georgetown and Austin Chalk formations

    SciTech Connect

    Julian, P.J.

    1982-09-01

    This study relates the success of detecting and analyzing naturally fractured systems in the Austin Chalk and Georgetown Formations from log evaluations. The Austin Chalk is composed principally of calcareous unicellular algal remains called cocospheres and their disunited, gearshaped, skeletal remains called cocoliths. The Georgetown Formation is a hard, dense, and finely brittle limestone. Both formations contain matrix porosity, but are dependent on open fracture systems for economical hydrocarbon production. Hence, defining and evaluating the developed fracture systems before setting an expensive casing string is important. The Dual Induction Log and the Compensated Neutron-Formation Density Log offers an economical method of evaluating these fracture systems. Case studies in Robertson, Milam, and Burleson Counties, Texas have shown that fracture systems near the wellbore can be detected. Attempts to determine the existence of hydrocarbons in fracture systems using logs were successful in the Austin Chalk and Georgetown Formations. Full core analyses were also successful in determining the existence of these fracture systems. However, obtaining core samples on all wells as a method of determining fracture systems is not recommended due to the high cost of coring.

  7. Typical well nonexistent in Austin Chalk

    Mickey, V.

    1981-11-01

    Discoveries of localized large-capacity reservoirs capable of sustaining high-rate production distinguish the current Austin Chalk play from past booms in the S.E. Texas trend. The chalk gained its reputation for high initial potentials with quick decline rates in the area of the Pearsall field in Frio County; this is southwest of the current focus of play in Burleson, Lee, Fayette, Washington, and Gonzales Counties. In this portion of the vast producing trend a different kind of rock exists - one that is highly fractured and gives up large amounts of hydrocarbons for a sustained period. An example of high-rate sustained production is in the Birch Creek area near Lake Somerville in Burleson County. Projected reserves should average 100,000 to 125,000 bbl/well. With varying amounts of associated gas from 400 MMCF to one billion cubic feet. Initial production tests on these wells range from 200 to 500 bopd and 200 MCFD to 3 MMCFD. After several months of production, the wells indicate capacity to hold up to initial performance.

  9. Solubility and dissolution kinetics of gypsum as a function of CO2 partial pressure: Implications for geological carbon sequestration William Wolfe, Philip Bennett The University of Texas at Austin, Jackson School of Geosciences

    2011-12-01

    The storage of carbon dioxide in deep saline (non-potable) aquifers has received increasing attention as a possible near term solution to the emission of carbon dioxide into the atmosphere. As a result of CO2 introduction, a wide array of geochemical reactions will occur involving both the aqueous phase and the solid mineral phase. Potential CO2 storage formations are typically saline Na:Cl or NaCa:ClSO4 type water. To gain insight into the dynamics of this system under the conditions of carbon sequestration we examined the solubility and dissolution/precipitation rates of gypsum in aqueous solutions as a function of CO2 partial pressure. Experimental variables ranged from 30-60 degrees C, 0.1-5 molar NaCl, and 1-130 atmospheres of CO2. Most standard geochemical models predict that gypsum solubility will increase with increasing dissolved CO2 due to the increased acidity driving the protonation of sulfate to form bisulfate: H+ + SO4= <=> HSO4- Thus decreasing sulfate concentration and driving further dissolution of gypsum. However, our findings show that increasing dissolved CO2 results in the precipitation of gypsum, with gypsum solubility decreasing by up to 30-50% at all temperatures examined. Solutions initially at equilibrium with gypsum will nucleate and precipitate gypsum as pCO2 increases. This behavior was predicted by Li and Duan, (2011) based on model results but no experimental evidence was found by the authors. Potential factors for this behavior include a decrease in the activity of water due to hydration of dissolved CO2, or possibly the destabilization of the CaSO4 neutral complex increasing the activity of free Ca++ and SO4= in solution, driving the precipitation of gypsum. We are exploring both of these possible scenarios. The saline aquifers of the Texas gulf coast are a potential target for carbon dioxide sequestration, and many of these aquifers have high Ca and SO4 concentrations due to reaction with gypsum. Precipitation of gypsum under high

    Socioeconomic position, racial/ethnic minority status, and other characteristics of the macro-environment may be important moderators of genetic influence on a wide array of psychosocial outcomes. Designed to maximize representation of low socioeconomic status families and racial/ethnic minorities, the Texas Twin Project is an on-going study of school-age twins (preschool through 12th grade) enrolled in public schools in the Austin, Texas and Houston, Texas metropolitan areas. School rosters are used to identify twin families from a target population with sizable populations of African-American (18%), Hispanic / Latino (48%), and non-Hispanic White (27%) children and adolescents, over half of whom meet U.S. guidelines for classification as economically disadvantaged. Initial efforts have focused on a large-scale, family-based survey study involving both parent and child reports of personality, psychopathology, physical health, academic interests, parent-child relationships, and aspects of the home environment. In addition, the Texas Twin Project is the basis for an in-laboratory study of adolescent decision-making, delinquency, and substance use. Future directions include geographic expansion of the sample to the entire state of Texas (with a population of over 25 million people) and genotyping of participating twins. PMID:23111007

    1990-05-01

    Since 1984, Amoco has pursued horizontal completions within the Burleson, Lee, and Fayette county areas of the Austin Chalk trend in central Texas. To date, two different drilling methods have been based to drill ten horizontal wells, which have been successfully completed and are presently producing. With use of both the short- and medium-radius drilling methods, significant cost reductions were realized and well performance was defined and optimized during the program. The program's overall success was directly attributable to the cooperative efforts of a team of drillers, reservoir engineers, and geologists. The drilling methods used by Amoco and the results of horizontal drilling in the Austin Chalk give production data that compare horizontal well performance against offset vertical well performance, which in this program resulted in horizontal/vertical well production ratios of 2.5 to 7. In addition, a significant relationship between length of horizontal well bore and production ratios was observed.

  11. Austin Chalk fracture mapping using frequency data derived from seismic data

    NASA Astrophysics Data System (ADS)

    Najmuddin, Ilyas Juzer

    Frequency amplitude spectra derived from P-wave seismic data can be used to derive a fracture indicator. This fracture indicator can be used to delineate fracture zones in subsurface layers. Mapping fractures that have no vertical offset is difficult on seismic sections. Fracturing changes the rock properties and therefore the attributes of the seismic data reflecting off the fractured interface and data passing through the fractured layers. Fractures have a scattering effect on seismic energy reflected from the fractured layer. Fractures attenuate amplitudes of higher frequencies in seismic data preferentially than lower frequencies. The amplitude spectrum of the frequencies in the seismic data shifts towards lower frequencies when a spectrum from a time window above the fractured layer is compared with one below the fractured layer. This shift in amplitudes of frequency spectra can be derived from seismic data and used to indicate fracturing. A method is developed to calculate a parameter t* to measure this change in the frequency spectra for small time windows (100ms) above and below the fractured layer. The Austin Chalk in South Central Texas is a fractured layer, and it produces hydrocarbons from fracture zones with the layer (Sweet Spots). 2D and 3D P-wave seismic data are used from Burleson and Austin Counties in Texas to derive the t* parameter. Case studies are presented for 2D data from Burleson County and 3D data from Austin County. The t* parameter mapped on the 3D data shows a predominant fracture trend parallel to strike. The fracture zones have a good correlation with the faults interpreted on the top of Austin Chalk reflector. Production data in Burleson County (Giddings Field) is a proxy for fracturing. Values of t* mapped on the 2D data have a good correlation with the cumulative production map presented in this study.

    The mitochondrial gene T-urf13 from maize (Zea mays L.) with Texas male-sterile (T) cytoplasm codes for a unique 13 kd polypeptide, T-URF13, which is implicated in cytoplasmic male sterility and sensitivity to the insecticide methomyl and to host-specific fungal toxins produced by Helminthosporium maydis race T (HmT toxin) and Phyllosticta maydis (Pm toxin). A chimeric gene coding for T-URF13 fused to the mitochondrial targeting peptide from the Neurospora crassa ATP synthase subunit 9 precursor was constructed. Expression of this gene in the yeast Saccharomyces cerevisiae yielded a polypeptide that was translocated into the membrane fraction of mitochondria and processed to give a protein the same size as maize T-URF13. Methomyl, HmT toxin and Pm toxin inhibited growth of yeast cells expressing the gene fusion on medium containing glycerol as sole carbon source and stimulated respiration with NADH as substrate by isolated mitochondria from these cells. These effects were not observed in yeast cells expressing T-URF13 without a targeting peptide. The results show that T-URF13 is sufficient to confer sensitivity to methomyl and the fungal toxins in a heterologous eukaryotic system, and suggest that mitochondrial localization of T-URF13 is critical for these functions.

    Considers the influence of fracture height, well site position, pump rates, types of fracture fluids, proppant concentrations, and leak-off controls. Careful attention to each of these factors can result in successful stimulation treatment and optimum production rates. The Austin Chalk trend stretches along the entire Gulf Coast from Mexico into Louisiana. Well position relative to faults and natural fractures in the Austin Chalk is the single most critical factor directly affecting productivity. Observations include: cross-linked fluids are necessary in most cases to achieve desired proppant concentration and distribution; there appears to be a relationship between fracture height and pump time; accurate estimates of fracture height are necessary to develop the desired propped fracture length; and leak-off in natural fractures potentially compromises well productivity.

  6. Horizontal technology helps spark Louisiana`s Austin chalk trend

    1996-04-29

    A handful of companies paced by some of the most active operators in the US are pressing the limits of horizontal technology to ramp up Cretaceous Austin chalk exploration and development (E and D) across Louisiana. Companies find applications in Louisiana for lessons learned drilling horizontal wells to produce chalk intervals in Texas in Giddings, Pearsall, and Brookeland fields. Continuing advances in horizontal well technology are helping operators deal with deeper, hotter reservoirs in more complex geological settings that typify the chalk in Louisiana. Better horizontal drilling, completion, formation evaluation, and stimulation techniques have enabled operators to produce oil and gas from formations previously thought to be uneconomical. Most of the improved capabilities stem from better horizontal tools. Horizontal drilling breakthroughs include dual powered mud motors and retrievable whipstocks, key links in the ability to drill wells with more than one horizontal lateral. Better geosteering tools have enabled operators to maintain horizontal wellbores in desired intervals by signaling bit positions downhole while drilling. This paper reviews the technology and provides a historical perspective on the various drilling programs which have been completed in this trend. It also makes predictions on future drilling successes.

  7. Characterization of the Austin Chalk producing trend

    Fracture patterns and reservoir dual characteristics are presented for a portion of the fractured Austin Chalk producing trend. The production histories of 1,235 wells from Giddings Field covering portions of Lee, Burleson, Washington, and Fayette counties were analyzed by decline curve analysis. Production of the average Austin Chalk well is usually characterized by an early rapid decline and a later slow decline. The average initial effective decline rate is about 90% per year, and lasts about six months to one year. For the later, less dramatic decline, the average is about 35% per year. Statistical results of well performance indicate no difficulty in finding oil in the Austin Chalk producing trend. However, areas of high fracture density must be encountered for a well to be profitable. A contour map of the iso-reserves was prepared for a better understanding of the fracture system and reservoir characteristics. Besides the general northeast-southwest production trend, the map shows anomalies in the fracture system and reservoir characteristics. A simple, rapid technique to estimate reservoir parameters directly from the double-decline behavior of log (rate) versus time curves is given. Values of flow capacity, storage capacity, dimensionless fracture storage parameter (..omega..), and dimensionless interporosity flow parameter (lambda) can be estimated by this technique.

    This paper reports on the completion of a Cretaceous Austin chalk horizontal oil well near a basaltic cone in the Uvalde volcanic field area of Dimmit County, Tex. The well is the HDP Inc. 1 autumn Unit, about 9 miles northeast to Carrizo Springs HDP, which stands for horizontal development and production, of Palo Alto, Calif., drilled the well on a farmout from American Exploration Co., Houston. It initially pumped and flowed 1,600 b/d of oil without stimulation from openhole. HDP drilled about 1,500 ft of horizontal and deviated hole in Austin chalk B-1, the producing horizon. Production in late August was about 500 b/d of oil, pending determination of proration unit size and allowable. The well, in the greater Pearsall field Austin chalk play along the Dimmit-Savala county line, is the first horizontal chalk producer in Elaine field. The field has produced mainly from Escondido sand, Olmos sand and Anacacho limestone, all in the Upper Cretaceous.

    Drilling activity across south Texas declined in 1983. Particularly hard hit were wildcat drilling and new gas field completions. Most significant successes were in deep Sligo gas exploration. Best production came from the developing deep Wilcox trend. Drilling for fractured Austin Chalk and for Paleozoic objectives had the largest declines relative to 1982. 1 figure, 7 tables.

  10. Seismic characterization of fracture orientation in the Austin Chalk using azimuthal P-wave AVO

    NASA Astrophysics Data System (ADS)

    Al-Shuhail, Abdullatif Adulrahman

    The Austin Chalk is a naturally fractured reservoir. Horizontal drilling, to intersect more fractures, is the most efficient method to develop this reservoir. Information about the predominant fracture orientation in the subsurface is essential before horizontal drilling. This information may be provided by cores, well logs, outcrop, or seismic data. In this study, I apply the azimuthal P-wave AVO method suggested by Ruger and Tsvankin (1997) on 2-D P-wave seismic data in Gonzales County, Texas, in order to determine the fracture azimuth in the Austin Chalk. The data also include oil production from horizontal wells and various types of well logs from vertical wells in the study area. The raw seismic data was imaged through a processing sequence that preserved the relative changes of amplitudes with offset. The stacked sections of some seismic lines showed that the top of the Austin Chalk reflector is laterally inconsistent. This is interpreted as an indication of fractured zones in the subsurface. This interpretation was strengthened by well logs that indicated fracturing in nearby wells. The AVO gradient of every CDP in a seismic line was determined. The median AVO gradient of all the CDPs in a seismic line was chosen to represent the whole line. The median AVO gradients of the lines and their corresponding line azimuths were used repeatedly to solve the azimuthal AVO equation, of Ruger and Tsvankin (1997), for the fracture azimuth using a combination of three different lines every time. The resultant fracture-azimuth solutions clustered about two, nearly perpendicular, azimuths: N58E and S31E. To resolve the inherently ambiguous solutions, the results from the production and well log data were used. Since the production and well log data indicated the presence of NE-trending fractures, I chose the N58E direction as the fracture azimuth. This result agreed with the results of other studies in surrounding areas, using different methods, about the fracture azimuth

    This study aimed to investigate which abilities are measured by the Austin Maze. One hundred and eight university students were administered a battery of eight neuropsychological tests including, the Austin Maze, the Tower of London, the Wisconsin Card Sort Test, Block Design, the Visual Spatial Learning Test, Digit Span Backwards, the Brown-Peterson Task and the Wide Range Achievement Test of Reading. Results indicated that visuospatial ability and memory both significantly contributed to performance on the Austin Maze, but differed in the degree to which they explained the performance depending on which measure of maze performance was employed. It appears that visuospatial ability is measured in early trials of the Austin Maze when individuals are orienting themselves to the path. In later trials individuals must call upon visuospatial memory to consolidate the details of the path. Executive function and working memory were not found to be significantly implicated in performance on the Austin Maze. PMID:9989018

  16. Evaluation of Austin Chalk from cores

    SciTech Connect

    Craft, J.M.

    1982-01-01

    To evaluate the economic and producing capacity of the Austin Chalk it is necessary to recognize the existence of 2 types of reservoirs, the matrix and the fracture reservoir. These 2 reservoirs are vastly different in their ability to store and produce hydrocarbons. A detailed definition of each and an understanding of their interdependence and interaction is necessary for a successful evaluation. The fracture reservoir can, in its natural state, have a very high permeability and capacity to transmit liquids or gas. It can have significant storage capacity. Matrix porosity and oil saturation indicate zones of matrix hydrocarbon accumulation. The permeability present would not flow significant amounts of fluid without the presence of a fracture system, either natural or artificially induced. Fractures must have sufficient permeability to reduce pressure in the fracture approaching well-bore flowing pressure.

  19. Induced microearthquake patterns and oil-producing fracture systems in the Austin chalk

    1998-04-01

    Microearthquakes collected during hydraulic stimulation allowed us to study fracture zones in Austin chalk oil reservoirs at two sites in the Giddings field, Texas. We deployed three-component, downhole geophone tools in production wells at depths of 2100 m and greater, one near Cook's Point, and two on the Matcek lease near Caldwell. At Cook's Point, we collected 482 microseismic events during a 4000 m 3 (25,000 bbl) hydraulic stimulation in an offset well. We collected 770 events during a similar operation on the Matcek lease. Many seismograms contained reflected phases that constrained location depths to the production zone at the base of the Austin chalk. By restricting all microearthquake locations to production depths, we located 20% of the Cook's Point events and over 60% of the Matcek events. At both sites we observed only the fracture wing closest to the observation stations. Locations formed elongated patterns extending up to 1 km from the stimulation well and trending N60°E, parallel to the known, regional fracture trend. The Cook's Point seismic zone measured over 100 m in width, while long stretches of the Matcek seismic zone narrowed to 30 m or less. We believe that the width of the seismic zone reflected the density of conductive fractures and thus, the volume of the reservoir accessed by the stimulation. Indeed, production rates in the first year following stimulation were much higher at Cook's Point, where we observed the wider of the two seismic zones.

    Bent-housing steerable downhole motors helped maintain course for a deep, hot, horizontal well in the Austin chalk. The Navasota Unit No. 1 was planned as a B zone, single downdip lateral, Austin chalk horizontal well with a maximum departure from vertical of 3,767 ft and a planned total depth (TD) of 17,342 ft measured depth (MD)/14,172 ft TVD. The Austin chalk was found significantly deeper in this well than planned, which resulted in an actual TD of 17,899 ft MD/14,993 ft TVD, the deepest (TVD) horizontal well in the Austin chalk to date. The well was spudded on August 6, 1994, and took 52 days to reach TD. The static bottom hole temperature was almost 350 F. The paper describes the well plan, drilling results, and the lateral section.

    Preliminary results of a program to observe Comet Austin (1990c1) from 16 April to 4 May and from 11 May to 27 May 1990 using the West Auxiliary of the McMath Solar Telescope on Kitt Peak, Arizona were presetned. The observations were made with a 15 cm duel-etalon Fabry-Perot scanning and imaging spectrometer with two modes of operation: a high resolution mode with a velocity resolution of 1.2 km/s and a medium resolution mode with a velocity resolution 10 km/s. Scanning data was obtained with an RCA C31034A photomultiplier tube and imaging data was obtained with a Photometrics LN2 cooled CCD camera with a 516 by 516 Ford chip. The results include: (1) information on the coma outflow velocity from high resolution spectral profiles of (OI)6300 and NH2 emissions, (2) gaseous water production rates from medium resolution observation of (OI)6300, (3) spectra of H2O(+) emissions in order to study the ionized component of the coma, (4) spatial distribution of H2O(+) emission features from sequences of velocity resolved images (data cubes), and (5) spatial distribution of (OI)6300 and NH2 emissions from medium resolution images. The field of view on the sky was 10.5 arcminutes in diameter. In the imaging mode the CCD was binned 4 by 4 resulting in 7.6 sec power pixel and a subarray readout for a field of view of 10.5 min.

    There have been more than 4500 laterals drilled in the Austin Chalk. This paper looks at estimated ultimate recoveries (EUR) on a barrels/acre basis for these Austin Chalk wells. Baffels/acre recoveries were computed by estimating ultimate per-well recoveries, drilled density and the impact of vertical production. The data were then analyzed for depletion and infill potential. Certain areas were selected for further study using an artificial neural network. The network was built and used to study the effects of parameters such as lateral length, first production date, structure of the Austin Chalk, etc. on these recoverable barrel/acre numbers. The methodology and regional results of the study are reviewed with detailed analyses shown in selected areas.

  2. Anomalous magnetization in the Austin Chalk: implications for magnetic studies in rocks and sediments

    Ellwood, B.B.; Balsam, W.L.

    1985-01-01

    Same day sampling and magnetic measurement of a one meter thick bed in a new road cut of the Upper Cretaceous Austin Chalk (northeastern Texas) has yielded a zone of anomalous magnetic behavior. Initial measurement of the anisotropy of magnetic susceptibility (AMS) indicated unusually high anisotropies and low bulk susceptibilities characteristic of a magnetocrystalline anisotropy which might be expected for the mineral siderite. Natural remanent magnetization (NRM) moments for these samples were low and directions were typical for samples which had acquired a normal geomagnetic field overprint at the site. Remeasurement of the NRM 3 days later yielded an increase in moment to >1 x 10/sup -3/ A/m for some samples and a direction parallel to the laboratory field. Isothermal remanent magnetization (IRM) of these samples indicates saturation at low induction values (<100 mT). AMS remeasurement over a period of weeks revealed a steady decrease in the anisotropy magnitudes and a change in direction. All of these results are consistent with the initial presence of siderite in the Austin Chalk samples. After sampling, exposure to the air, and subsequent oxidation in the laboratory, the siderite appears to have altered to ..gamma..Fe/sub 2/O/sub 3/ (maghemite), increasing the magnetic moment and changing NRM and AMS directions in these samples. It is predicted that changes will reflect the continued conversion from the less stable ..gamma..Fe/sub 2/O/sub 3/ to ..cap alpha..Fe/sub 2/O/sub 3/ (hematite). Evaluation of this possibility is currently in progress.

  6. Controls on fracture distribution in the Giddings Austin Chalk

    SciTech Connect

    Wagner, D.T. )

    1990-09-01

    Fracture distribution in the Giddings Austin Chalk is controlled by both structure and the stratigraphy of the Austin Group. Parameters that most affect reservoir performance include fracture width, height, and spacing, as well as the number of fracture sets and their orientations. Lateral variance of these parameters is a function of structural position, while vertical change is related to stratigraphy. The Austin Chalk productive trend is thought to coincide with the hingeline of the Gulf Coast basin, where extension has been concentrated during subsidence of the basin. Fracturing is attributed to a number of mechanisms including normal faulting, bending over buried structures, gravity creep, differential compaction, and aquathermal pressuring. A change in structural style from faulting to flexure takes place from west to east across the Giddings field, accompanied by a change in fracture distribution. In the west, fractures develop only in close proximity to faults whereas in the east they are more widely distributed over broad warps. Stratigraphic controls include lithology, porosity, bed thickness, and ductility contrast between adjacent beds. The Austin Chalk consists of sparse biomicrite interbedded with marls, shales, and clay seams. In general, thin beds are more highly fractured than thick beds, and clean limestone is more highly fractured than marl or shale. Where the more ductile marls and clays exceed a critical thickness, fractures tend to terminate within individual chalk beds, resulting in barriers to vertical flow within the reservoir.

    June 2007 was one of the wettest Junes on record for the state of Texas. Starting in late May, a string of low-pressure systems settled in over the U.S. Southern Plains and unleashed weeks of heavy to torrential rain. During the final week of June, much of Texas, Oklahoma, and Kansas received more than 330 percent of their average rainfall, said the National Climatic Data Center. The widespread heavy rain brought deadly floods to the entire region. On July 6, the Associated Press reported that every major river basin in Texas was at flood stage, an event that had not occurred since 1957. In addition to causing floods, the rains stimulated plant growth. The grassy, often arid, plains and plateaus of northern Mexico (bottom left), Texas (center), and New Mexico (top, left of center) burst to life with dense vegetation as this vegetation anomaly image shows. Regions where plants were growing more quickly or fuller than average are green, while areas where growth is below average are brown. Most of Texas is green, with a concentrated deep green, almost black, spot where vegetation growth was greatest. This area of western Texas is where the Pecos River flows out of New Mexico and heads southeast to the Rio Grande. In the darkest areas, vegetation was more than 100 percent above average. The brown spots in northeastern Texas and Oklahoma (top, right of center) may be areas where persistent clouds or water on the ground are hiding the plants from the satellite's view. Plants may also be growing less than average if swamped by too much rain. The image was made with data collected by the SPOT satellite between June 11 and June 20, 2007. NASA imagery created by Jesse Allen, Earth Observatory, using SPOT data provided courtesy of the USDA Foreign Agricultural Service and processed by Jennifer Small and Assaf Anyamba of the GIMMS Group at NASA GSFC.

  9. Horizontal wells up odds for profit in Giddings Austin chalk

    Maloy, W.T. )

    1992-02-17

    This paper reports on horizontal drilling in the Giddings field Austin chalk which has significantly improved average well recoveries and more than offset increased drilling costs. Although not the panacea originally promoted, horizontal drilling, in Giddings field, offers economic profits to the average investor. Economic analysis indicates that the typical investor is making money by earning returns in excess of market values. Field-wide development will, therefore, remain active unless oil prices or average well recoveries fall below $12/bbl or 112,000 bbl of oil equivalent (BOE), respectively. The application of technological innovation in the Giddings field may culminate in the drilling of over 2,000 horizontal Austin chalk wells, and has conceivably increased recoverable reserves by 400 million BOE.

    Railroads continue to play an important role in moving domestic and international freight through Texas, contributing to economic growth in the state. This study addresses the potential for implementing a rail planning process in the Texas Department of Transportation. In order to accomplish this, successful rail planning processes at other US departments of transportation were evaluated and exemplary programs identified. Three reports were published addressing a variety of findings. The first, published by the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin, provides an overview and examination of 32 state rail policies, plans, and programs for both passenger and freight traffic. The second report, also published by the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin, provides information on exemplary state rail programming and planning based on case studies of California, Florida, North Carolina, and the state of Washington. The third report, published by the Texas Transportation Institute at Texas A and M University, provides (1) a framework for rail planning in Texas, (2) identification of current rail issues in Texas, (3) a case study on urban rail rationalization, and (4) a characterization of the rail system in Texas. In each report, detailed appendices are provided to complement the findings and recommendations. In this project summary report, an implementation schedule is recommended to institute rail planning in the Texas Department of Transportation.

  11. The Consequences of Physics GRE Requirements for Graduate School: A Case Study at UT Austin

    Siders, Jennifer L. W.

    1996-05-01

    Five years ago the Physics Department at the University of Texas at Austin began requiring a 700 on the Physics GRE for admission to Ph.D. Candidacy. This requirement eventually led the admissions committee to use an unofficial requirement of 600 for graduate admissions because of the difficulty students had bringing up their scores. Shortly thereafter, we noticed a dramatic drop in the number of women graduate students entering our department. Three years worth of data from American applicants to the UT Physics department was analyzed (31 women, 363 men). The 600 cutoff eliminated 55 percent of the female applicants and 24 percent of male applicants. Only 10 percent of the women applicants had over a 700 while 47 percent of the male applicants had already achieved a score higher than 700. The average Physics GRE score for male applicants was 100 points higher than the average female applicants score. The correlation between undergraduate GPA and Physics GRE score is very small. 97 percent of the female applicants and 90 percent of the male applicants had GPA's over a 3.00. We will discuss our results and the changes that were made at UT.

    Asquith, William H.

    1998-01-01

    Peak-flow frequency for 38 stations with at least 8 years of data in natural (unregulated and nonurbanized) basins was estimated on the basis of annual peak-streamflow data through water year 1995. Peak-flow frequency represents the peak discharges for recurrence intervals of 2, 5, 10, 25, 50, 100, 250, and 500 years. The peak-flow frequency and drainage basin characteristics for the stations were used to develop two sets of regression equations to estimate peak-flow frequency for tributaries of the Colorado River in the study area. One set of equations was developed for contributing drainage areas less than 32 square miles, and another set was developed for contributing drainage areas greater than 32 square miles. A procedure is presented to estimate the peak discharge at sites where both sets of equations are considered applicable. Additionally, procedures are presented to compute the 50-, 67-, and 90-percent prediction interval for any estimation from the equations.

    Three high-coulomb explosively actuated opening switches which have demonstrated reliability and fast switching in railgun experiments are presented. Two of these switches first provide a low-conductivity path to transfer energy from homopolar generators to inductive energy stores and then open to commutate current to the railgun. One is a monolithic aluminum element with machined stress concentrations, and the other uses reloadable cartridges mechanically clamped. The third switch is designed to interrupt current in a compulsator-powered railgun experiment. In the event of a short-circuit fault, the switch automatically opens in order to prevent overheating of the compulsator armature windings. The design and excellent performance of these switches are reviewed.

    The multiple-comparison tests indicate that, for some constituents, a single sampling site for a constituent or property might adequately characterize the water quality of Lake Travis for that constituent or property. However, multiple sampling sites are required to provide information of sufficient temporal and spatial resolution to accurately evaluate other water-quality constituents for the reservoir. For example, the water-quality data from surface samples and from bottom samples indicate that nutrients (nitrogen, phosphorus) might require additional sampling sites for a more accurate characterization of their in-lake dynamics.

  9. Fault controlled sequential vein dilation: competition between slip and precipitation rates in the Austin Chalk, Texas

    NASA Astrophysics Data System (ADS)

    Lee, Young-Joon; Wiltschko, David V.

    2000-09-01

    Multi-layered calcite veins in a dilatant jog of a left-stepping, left-slipping shallowly buried fault segment are composed of alternating millimeter- to submillimeter-thick calcite veinlets and host lithons forming a coarse 'crack-seal' texture. The grain fabrics in calcite veinlets are mostly equant or irregular, suggesting face-controlled grain growth in a fluid-filled cavity. The relatively thick veinlets can be developed by progressive fault slip and veinlet opening simultaneously with calcite precipitation under low effective stress. Continuous changes in the oxygen isotopic compositions of the calcite veinlets along the length of veins suggest that the individual calcite veinlets were sequentially developed from the footwall to the hanging wall. There is no particular evidence that these veins represent excursions in fluid pressure or instantaneous fracture opening related to episodic fault slip; the fracture formation and filling cycle could have taken place along a continuously slipping fault contained within a porous rock with normal fluid pressure.

    The reflectance of huminite in 19 cuttings samples was determined in support of ongoing investigations into the coal bed methane potential of subsurface Paleocene and Upper Cretaceous coals of South Texas. Coal cuttings were obtained from the Core Research Center of the Bureau of Economic Geology, The University of Texas at Austin. Geophysical logs, mud-gas logs, driller's logs, completion cards, and scout tickets were used to select potentially coal-bearing sample suites and to identify specific sample depths. Reflectance measurements indicate coals of subbituminous rank are present in a wider area in South Texas than previously recognized.

  11. Opportunities for horizontal drilling in Texas

    SciTech Connect

    Finley, R.J.; Laubach, S.E.; Tyler, N.; Holtz, M.H. )

    1991-03-01

    To date, horizontal drilling in Texas has been effective in achieving production increases where natural fracturing is significant, as in the Pearsall field of the Austin Chalk trend of south Texas. Projected average ultimate recoveries of 500,000 bbl of oil and 500 mmcf of gas per horizontal well compare with 75,000 bbl and 82 mmcf for vertical wells in that field. In addition to increasing production from naturally fractured reservoirs, horizontal drilling applications can enhance production where coning problems exist, where the reservoir zone is thin, where a gravity drainage mechanism exists, or where macroscale heterogeneity can be overcome to produce from complex, compartmentalized reservoirs. Major Texas reservoirs have been classified into 47 oil plays and 73 gas plays that are useful in evaluating the application of horizontal drilling. Geological character amenable to horizontal drilling is evident in at least 10 oil plays containing 144 reservoirs, more than two Bbl of proved reserves, and eight Bbbl of uncovered mobile oil. At least seven gas plays containing more than 124 reservoirs with cumulative production of more than 19.7 tcf are amenable to horizontal drilling. Tight gas reservoirs may benefit from multiple hydraulic fracture treatments from horizontal well sections drilled parallel to the minimum horizontal stress direction. Although play analysis defines general suitability, applications of horizontal drilling depend upon geologic, engineering, and, most importantly, economic assessments of specific prospects. Increased understanding of fractured reservoirs and of scales of reservoir heterogeneity will enhance future applications.

  12. Opportunities for horizontal drilling in Texas

    SciTech Connect

    Finley, R.J.; Laubach, S.E.; Tyler, N.; Holtz, M.H.

    1990-01-01

    Highly productive wells drilled in the Pearsall field (Austin Chalk) of South Texas have shown that horizontal drilling is an extremely effective technique for developing unrecovered oil and natural gas, particularly in mature hydrocarbon provinces that contain natural fractures. Production can also be enhanced where the reservoir-quality zone or the oil column is thin or where gravity-drainage production occurs. Although they are not current targets of horizontal drilling activity, many other kinds of reservoirs contain depositional heterogeneities that interfere with recovery by vertical wells. Use of horizontal drilling to tap multiple reservoir compartments in these reservoirs has significant potential but has yet to be fully tested. The resource target of unrecovered mobile oil in the nine Texas plays and subplays discussed in this report, amounting to more than 8 billion barrels of oil, warrants further testing of horizontal drilling in areas of depositional heterogeneities and multiple reservoir compartments. The authors summarize geological and engineering characteristics of selected formations in Texas that have been or are potential targets for horizontal drilling.

    Skilled formation evaluation is essential to economic well completions in the Cretaceous carbonate trend of South and Central Texas. The Austin chalk and Buda lime wells within this trend are known for high initial production rates followed by rapid production decline probably due to completion in zones of insufficient porosity and permeability. Therefore, the proper use of geophysical wireline data to locate fractures and determine fracture quality and hydrocarbon potential prior to setting casing is an essential element in evaluating the economics of any given well. This work details current successful evaluation procedures utilized in the trend. 11 refs.

    A spectrum of Comet Austin (1988 c1) has been obtained from 910 to 1180 A. Three bright emission lines were detected, including a forbidden oxygen line (1128 A), which are attributable to radiative pumping of neutral oxygen by solar Lyman-beta. The relative strengths of the observed features should prove to be a useful diagnostic of the physical conditions and radiation fields in cometary comae. In addition, the absence of strong spectral features from highly volatile species such as He, Ar, or N2 can be used to place constraints on the thermal environment under which the comet was formed and has been processed.

    Ultraviolet spectra of comet Austin (1982) obtained in July 1982 at heliocentric distances ranging from 1.10 to 0.81 AU preperihelion with the IUE reveal that the comet is very similar in chemical composition and appearance to comet Bradfield (1979X). In addition, the derived H2O production rate is found to vary with heliocentric distance as r to the -3.6, similar to the r to the -3.7 behavior found for comet Bradfield. It is pointed out, however, that the limited sample rate precludes the observation of the short-term variations which could be produced by a rotating nonuniform cometary nucleus.

    So called ``water-fracs`` have obtained excellent results in the Austin Chalk formation of Giddings field. This inexpensive treatment uses high volumes of water but no proppant. The reasons the treatment is successful include imbibition, gravity drainage, skin damage removal, and repressurization of the reservoir to enhance recovery. Union Pacific Resources Co. (UPRC) has treated about 250 vertical and 150 horizontal wells with very high economic success rates. Incremental recoveries from horizontal well water fracs alone exceed 5 million bbl of oil equivalent (6 Mcf = 1 bbl).

    Comprehension of the alloying effects of major candidate light elements on the phase diagram and elasticity of iron addresses pressing issues on the composition, thermal structures, and seismic features of the Earth's core. Integrating this mineral physics research with the educational objectives of the CAREER award was facilitated by collaboration with the University of Texas at Austin's premier teaching program, UTeach. The UTeach summer outreach program hosts three one-week summer camps every year exposing K-12th graders to university level academia, emphasizing math and science initiatives and research. Each week of the camp either focuses on math, chemistry, or geology. Many of the students were underrepresented minorities and some required simultaneous translation; this is an effect of the demographics of the region, and caused some language barrier challenges. The students' opportunity to see first-hand what it is like to be on a university campus, as well as being in a research environment, such as the mineral physics lab, helps them to visualize themselves in academia in the future. A collection of displayable materials with information about deep-Earth research were made available to participating students and teachers to disseminate accurate scientific knowledge and enthusiasm. These items included a diamond anvil cell and diagrams of the diamond crystal structure, the layers of the Earth, and the phases of carbon to show that one element can have very different physical properties purely based on differences in structure. The students learned how advanced X-ray and optical laser spectroscopies are used to study properties of planetary materials in the diamond anvil cell. Stress was greatly placed on the basic mathematical relationship between force, area, and pressure, the fundamental principle involved with diamond anvil cell research. Undergraduate researchers from the lab participated in the presentations and hands-on experiments, and answered any

    Urbanization can cause significant changes to both flow and water quality in streams and tributaries. In the Austin, Texas, area, previous studies have demonstrated that streamwater strontium isotope compositions (87Sr/86Sr) correlate with measures of urbanization when comparing non-urbanized streams to their urban counterparts. The inclusion of municipal water into natural surface water is inferred from the mean 87Sr/86Sr value found in urbanized streams, which falls between the high value in treated municipal water and the lower values found in local surface streams sourcing from non-urbanized catchments. Fluoride is added to municipal tap water in the treatment process, and a correlation between 87Sr/86Sr and fluoride is observed in streamwater sampled from the watersheds around Austin. These relationships represent some of the principal findings reported in Christian et al. (2011). Current research is testing the hypothesis that municipal water influx in urban areas is a primary modifier of stream- and spring-water chemistry in a single watershed that contains a strong gradient in land use. We compare 87Sr/86Sr and other chemical constituents with potential contributing endmembers, such as municipal tap water and wastewater, local soil and rock leachates, and land use within the Bull Creek watershed. As a consequence of the history of land development, some Bull Creek tributaries are sourced and flow almost entirely in fully-developed areas, whereas others are located in protected natural areas. Thirteen tributaries were monitored and classified as either urbanized or non-urbanized based upon land use within the tributary catchment. Springs in the Bull Creek watershed were also sampled and are similarly classified. The Bull Creek watershed is composed of Lower Cretaceous limestone with significantly lower 87Sr/86Sr than that of municipal water taken from the Lower Colorado River, which is underlain in part by Precambrian rocks upstream of Austin. There are

    The Texas Intense Positron Source (TIPS) is a reactor-based low-energy positron beam facility utilizing some novel techniques in positron beam production. This facility will be located at the University of Texas (UT) at Austin Nuclear Engineering Teaching Laboratory (NETL) and is being developed by UT Austin and UT Arlington researchers. TIPS will use a large area (total area of 900-1800 cm 2) 64Cu source to supply fast β + particles for subsequent moderation to form an intense monoenergetic positron beam in the energy range of 0-50 keV with an expected intensity of 10 8 e +/s. Natural copper will be neutron activated near the core of the NETL 1 MW TRIGA Mark II research reactor to produce the 64Cu isotope. The activated source will be transported to the moderator/remoderator assembly, outside the biological shield of the reactor. This assembly combines the primary moderation and posterior remoderation of the fast β + particles into one stage using solid Kr to produce a low-energy positron source of a few eV with a diameter of 8 mm. The low-energy positron beam is then extracted by an electrostatic modified SOA gun and after further acceleration to 5 keV, the beam is focused onto the object slit of a 90° bending magnet. After further focusing and another 90° bend, the beam enters the main accelerator/decelerator that transports the beam onto the target for experimentation. The components of TIPS have been manufactured and are currently being optimized. In this communication we present some of the details of the TIPS facility and furthermore briefly discuss its intended applications.

    The Lower Colorado River Authority (LCRA) in Austin, Texas, manages the Highland Lakes reservoir system in Central Texas, a series of six lakes on the Lower Colorado River. This system provides water to approximately 1.1 million people in Central Texas, supplies hydropower to a 55-county area, supports rice farming along the Texas Gulf Coast, and sustains in-stream flows in the Lower Colorado River and freshwater inflows to Matagorda Bay. The current, prolonged drought conditions are severely taxing the LCRA's system, making allocation and management decisions exceptionally challenging, and affecting the ability of constituents to conduct proper planning. In this work, we further develop and evaluate season-ahead statistical streamflow and precipitation forecast models for integration into LCRA decision support models. Optimal forecast lead time, predictive skill, form, and communication are all considered.

    Far-UV rocketborne spectrometer observations have established upper Ar and He abundance limits on Comet Austin. These limits indicate, relative to solar abundance, that Comet Austin is depleted in He/O and no more than 30-times enriched in Ar/O. Implications of these values for thermal conditions experienced during formation and evolution are discussed.

    1993-01-01

    3-micron and 10-micron spectra and IR photometry of the dynamically new Comet Austin 1990 V were obtained for March-May 1990. An unusual 9-11 micron emission feature 15-20 percent above the continuum is evident at 0.78 AU postperihelion. The shape, in particular a peak at 11.06 micron, differs from that seen in Halley and several other comets, suggesting a difference in the mineralogy of the silicate grains. The 3.1-7.7 micron spectrum at 0.35 AU shows no obvious feature; feature/continuum contrast of the 3.36 micron emission feature is less than about 5 percent. Based on the IR photometry and a dust model weighted toward small grains, the dust production rate on 6 May at 0.78 AU was about 3 x 10 exp 5 g/s. The corresponding dust/gas mass ratio was about 0.1, classifying Austin as a dust-poor comet. This designation refers only to the relative dust cross section, not to the total mass.

    The spatial distributions of the brightest features in the far-UV spectrum of Comet Austin were measured, and it is found that they are generally similar to those found for Comet Halley during two rocket observations in 1986. As in Halley, the CO profile can be fit to a radial outflow profile for a source whose size is smaller than the instrumental spatial resolution. Neither the shape nor the magnitude of the extended atomic carbon profiles, however, can be satisfactorily explained by the photodissociation of CO. No evidence is found for an extended source of CO in the coma; thus, suggestions that the additional carbon can come directly from grains are difficult to accept since Austin is a low-dust comet. The presence of the O I 1356 A feature implies that there is a photoelectron excitation source in the coma. The measured O I 1304 A distribution is consistent with H2O being the dominant source of oxygen in the coma. The atomic sulfur profile matches that expected for a daughter product of relatively short-lived parents.

    Thermal-infrared (10 and 20 micron) images of Comet Austin were obtained on UT 30.6 Apr., 1.8, 2.8, and 3.6 May 1990. The NASA-Marshall Space Flight Center 20 pixel bolometer array at the NASA 3 meter Infrared Telescope Facility in Hawaii was used. The 10.8 micron (FWHM = 5.3 microns) maps were obtained with maximum dimensions of 113 arcsec (57,500 km) in RA and 45 arcsec (23,000 km) in declination, with a pixel size of 4.2 x 4.2 arcsec. A smaller, 45 x 18 arcsec, map was obtained in the 19.2 micron (FWHM = 5.2 microns) bandpass. At the time of these observations Comet Austin's heliocentric and geocentric distances were 0.7 and 0.5 AU respectively. The peak flux density (within the brightest pixel) was 23 + or - 2 Janskys for the first three dates and only marginally lower the last day; i.e., within the observational uncertainties no evidence was found for day-to-day variability like that observed in Comet Halley. A dynamical analysis of the morphology of the extended dust emission is used to constrain the size distribution and production rate of the dust particles. The results of this analysis are compared with similar studies carried out on comets P/Giacobini-Zinner, P/Brorsen-Metcalf, P/Halley, P/Tempel 2, and Wilson (1987).

    Located at TRI/Austin, and operated under a Department of Defense contract, is the Nondestructive Testing Information Analysis Center (NTIAC). This is a full service Information Analysis Center sponsored by the Defense Technical Information Center (DTIC), although services of NTIAC are available to other government agencies, government contractors, industry and academia. The principal objective of NTIAC is to help increase the productivity of the nation`s scientists, engineers, and technical managers involved in, or requiring, nondestructive testing by providing broad information analysis services of technical excellence. TRI/Austin is actively pursuing commercialization of several products based on results from outside funded R and D programs. As a small business, TRI/Austin has limited capabilities for large scale fabrication, production, marketing or distribution. Thus, part of a successful commercialization process involves making appropriate collaboration arrangements with other organizations to augment TRI/Austin`s capabilities. Brief descriptions are given here of two recent commercialization efforts at TRI/Austin.

    Meaningful measurements with respect to the cometary Balmer-alpha (H-alpha) emission are difficult and require the use of special equipment. The first ground-based observations of H-alpha emission from a cometary hydrogen corona were conducted on comet Kohoutek 1973 XII with a large-aperture Fabry-Perot spectrometer installed at the McMath solar telescope at Kitt Peak National Observatory. The present investigation is concerned with the second ground-based observations of cometary H-alpha emission carried out during the apparition of comet Austin 1982g. A 150 mm dual-etalon Fabry-Perot spectrometer was employed in the experiment. Use was made of an observatory which is designed for the high spectral resolution study of faint extended sources such as interstellar and geocoronal emission lines. The investigation demonstrates that hydrogen production rates from comets as faint as about 7th magnitude can be routinely measured from the ground at minimal cost.

    A cold neutron source has been designed, constructed, and tested by the Nuclear Engineering Teaching Laboratory (NETL) at The University of Texas at Austin. The Texas Cold Neutron Source (TCNS) is located in one of the beam ports of the NETL 1-MW TRIGA Mark II research reactor. The main components of the TCNS are a cooled moderator, a heat pipe, a cryogenic refrigerator, and a neutron guide. 80 ml of mesitylene moderator are maintained at about 30 K in a chamber within the reactor graphite reflector by the heat pipe and cryogenic refrigerator. The heat pipe is a 3-m long aluminum tube that contains neon as the working fluid. The cold neutrons obtained from the moderator are transported by a curved 6-m long neutron guide. This neutron guide has a radius of curvature of 300 m, a 50 × 15 mm cross-section, 58Ni coating, and is separated into three channels. The TCNS will provide a low-background subthermal neutron beam for neutron capture and scattering research. After the installation of the external portion of the neutron guide, a neutron focusing system and a Prompt Gamma Activation Analysis facility will be set up at the TCNS.

    The one year internship required for partial fulfillment of the Doctor of Engineering Degree was completed at the Governor's Energy Management Center in Austin, Texas. The intern worked for the State Agencies Department of the Energy Management Center. The intern was involved in a variety of projects, but the primary projects requiring the greatest time were the involvement with the design reviews for energy efficiency of new prisons being constructed in Texas, conducting energy management audits at 18 major state universities, and the technical and administrative assistance to the State Cogeneration Council. Other project involvement included managing the preliminary engineering design of the cogeneration facility at Austin State Hospital, responsibility for applying for a $1.4 million dollar crude oil refund on the behalf of all state agencies in Texas, and assisting in the planning and coordination of the $48 million Revolving Loan Program for the state of Texas. The internship taught many things about management and communications. The experience also provided a better understanding of how the state and federal government operate. The greatest contribution of the internship experience was the improvement of the intern's written and oral communication skills.

    The south Texas report includes 58 counties within Texas Railroad Commission Districts 1, 2, and 4, and portions of the Texas offshore. Overall exploratory activity decreased 9% from 1980 totals. District 1 experienced an increase in activity of 7%; in both Districts 2 and 4 there was a downturn of 9%. Average depth figures continued to increase; in Districts 1, 2, and 4, wells were drilled an average of 31%, 7%, and 4% deeper, respectively. The success rate of District 1 improved from 37% to 51%, whereas District 2 fell from 66% to 48% and District 4 remained the same at 60%. There were 27 new onshore Miocene reservoirs found; however, there were no new fields discovered. There were 272 Oligocene discoveries made onshore in 1981. In the Frio trend, successful exploratory activity was down 27% with 204 new reservoirs found. Vicksburg trend activity levels remained steady with 68 new discoveries made. Eocene discoveries totaled 168, down 23% from 1980 totals. The Wilcox Group, the dominant Eocene producing trend, was successfully explored for 109 new reservoirs. Activity in the Cretaceous trend was up 56% in 1981 with 148 discoveries made. The most concentrated drilling was in the Austin Chalk-Buda producing areas of Frio, Gonzales, and Wilson Counties. There were 2 Jurassic discoveries, 1 in McMullen County and the other in Bastrop County. Exploration activity in the south Texas offshore area resulted in the finding of 13 new reservoirs, 5 of which were new fields.

  18. Ozone Air Quality Impacts of Shale Gas Development in South Texas Urban Areas

    NASA Astrophysics Data System (ADS)

    Chang, C.; Liao, K.

    2013-12-01

    Recent technological advances, mainly horizontal drilling and hydraulic fracturing, and continued drilling in shale, have increased domestic production of oil and gas in the United State (U.S.). However, shale gas developments could also affect the environment and human health, particularly in areas where oil and gas developments are new activities. This study is focused on the impacts of shale gas developing activities on summertime ozone air quality in South Texas urban areas since many of them are already ozone nonattainment areas. We use an integrated approach to investigate the ozone air quality impact of the shale gas development in South Texas urban areas. They are: (1) satellite measurement of precursors, (2) observations of ground-level ozone concentrations, and (3) air mass trajectory modeling. Nitrogen dioxide (NO2) is an important precursor to ozone formation, and summertime average tropospheric nitrogen dioxide (NO2) column densities measured by the National Aeronautics and Space Administration's Ozone Monitoring Instrument increased in the South Texas shale area (i.e., the Eagle Ford Shale area) in 2011 and 2012 as compared to 2008-2010. The U.S. Environmental Protection Agency's ground-level observations showed summertime average and peak ozone (i.e., the 4th highest daily maximum 8-hour average ozone) concentrations slightly increased from 2010 to 2012 in Austin and San Antonio. However, the frequencies of peak ozone concentrations above the 75ppb ozone standard have been significantly increasing since 2011 in Austin and San Antonio. It is expected to increase the possibilities of violating the ozone National Ambient Air Quality Standard (NAAQS) for South Texas urban areas in the future. The results of trajectory modeling showed air masses transported from the southeastern Texas could reach Austin and San Antonio and confirmed that emissions from the Eagle Ford Shale area could affect ozone air quality in South Texas urban areas in 2011 and 2012

    1993-03-01

    More than 1,300 Austin Moore hemiarthroplasties have been reviewed in the literature, with no reports of fracture of the stem. Many patients with these hip implants had good function. The lack of stem fractures in patients with good functions has not been explained and contrasts with stem fractures that have occurred in patients with cemented prostheses of other designs during the same time. We used three-dimensional finite-element analysis and free-body diagrams to explain the lack of fractures for this device by a description of the probable load-transfer mechanisms between the prosthesis and the bone. Results from our finite-element analysis indicate that, with good calcar-collar support, the stresses in the stem are small because the stem portion of the prosthesis and the bone are uncoupled and, consequently, do not share the resultant bending moment of the head and abductor forces. If the stem is coupled to the bone so that the resultant bending moment is shared, high stresses in the stem are predicted; such stresses are inconsistent with the complete absence of fractures of these prostheses. The results of the finite-element analysis further showed that loss of calcar-collar support with proximal fixation through the fenestrations resulted in high stresses in the stem and stress shielding of the proximal medial cortex. The uncoupled prosthesis also may be modeled with a free-body diagram as a three-force member loaded at the head, stem tip, and in the proximal region. With this model, it can be shown that the reaction force of the stem tip, and thus the peak bending stress in the stem, increases as calcar-collar support is decreased. If there is no calcar-collar support, proximal support must be provided by some combination of integration of bone in the fenestrations and wedging due to the lateral-medial taper of the device. Stresses in the stem are largest when there is no wedging, but high stresses develop in the cancellous bone in the fenestrations. When

    Extensive roadcuts on U.S. Highway 90 in the vicinity of Langtry in west Texas display superb exposures of well-bedded chalky limestones comprising the lowest 27 m (89 ft) of the Austin Chalk equivalent. The limestone occurs as highly persistent beds averaging about 40 cm (15 in.) thick and separated by shale partings averaging 2-3 cm (about 1 in.). Limestone-shale contacts are very sharp. Nannoplankton indicate a Turonian to Santonian age and an outer shelf source; sedimentary features suggest redeposition by moderately low-density turbidity currents in a midfan setting characterized by distinctive distributary channels with channel-mouth bars and levees. The informal term Langtry formation is applied to these strata, which flank shallower water platform facies to the east, north, and west (Austin Chalk and San Vicente Member of the Boquillas Formation), and pass into basinal limestones of the San Felipe Formation in the La Mula basin to the south.

    Comet Austin (1989c1) was observed post-perihelion at a heliocentric distance near 1.25 AU. The wavelength range was from the atmospheric cutoff at 3000 to 4000 A. The coma spectra were calibrated into flux units and the contaminating sky spectrum and solar scattered light continuum were subtracted, leaving an ultraviolet spectrum of about 1.5-A resolution and excellent signal-to-noise ratio. The spectrum is dominated by emissions from OH, NH, CH, C3, and CN, some of the weaker emissions of which are seen here for the first time. More bands of CO(2+) were found than in any previous investigation and several intensity anomalies were noted; H2CO, OH(+), NCN, N(2+), and CN(+) may be present. Several emission features well above the noise level remain unidentified. The relative intensities of the OH and CN bands agree with the predictions of resonance fluorescence when one considers the potential effects of contamination by other molecules. The effects of the ozone absorption spectrum are not fully removed by the data-reduction process, although this does not affect these results.

    Pressure build-up data collected from wells in the Giddings Austin Chalk field have been analyzed through use of techniques currently available to the petroleum industry. The slope of ..delta..T vs. ..delta..P, along with a Horner graph and knowledge of well history, should indicate which method of analysis is applicable. The operator should know what kind of stimulation, if any; was performed on the well and the degree of success. A Horner graph, along with a graph of ..delta..T vs. ..delta..P should be plotted as a matter of course. Information gained from proper analysis of build-up data may be used both in well diagnosis and in prediction of well performance. In well diagnosis, a pressure buildup-falloff test is one of the few means of analyzing a problem well. Properly analyzed build-up data will give estimates of average reservoir pressure, in situ permeability, and fracture length. These data will aid in fracture optimization, reserve prediction, and performance prediction.

    Updated age assignments and new collections of molluscan fossils from lower Cenomanian through upper Campanian strata in Texas permit a much refined biostratigraphic correlation with the rocks of New Mexico and the Western Interior. Generic names of many Late Cretaceous ammonites and inoceramid bivalves from Texas are updated to permit this correlation. Strata correlated in the west-to-east transect include the lower Cenomanian Beartooth Quartzite and Sarten Sandstone of southwest New Mexico, and the Eagle Mountains Formation, Del Rio Clay, Buda Limestone, and. basal beds of the Chispa Summit, Ojinaga, and Boquillas Formations of the Texas-Mexico border area. Middle Cenomanian strata are lacking in southwestern New Mexico but are present in the lower parts of the Chispa Summit and Boquillas Formations in southwest Texas. Upper Cenomanian and lower Turonian rocks are present at many localities in New Mexico and Texas in the Mancos Shale and Chispa Summit, Ojinaga, and Boquillas Formations. Middle Turonian and younger rocks seem to be entirely nonmarine in southwestern New Mexico, but they are marine in the Rio Grande area in the Chispa. Summit, Ojinaga, and Boquillas Formations. The upper part of the Chispa Summit and Boquillas contain late Turonian fossils. Rocks of Coniacian and Santonian age are present high in the Chispa Summit, Ojinaga, and Boquillas Formations, and in the lower part of the Austin. The San Carlos, Aguja, Pen, and Austin Formations contain fossils of Campanian age. Fossils representing at least 38 Upper Cretaceous ammonite zones are present along the transect. Collections made in recent years in southwestern New Mexico and at Sierra de Cristo Rey just west of downtown El Paso, Texas, have been well treated and do not need revision. Taxonomic names and zonations published in the pre-1970 literature on the Rio Grande area of Texas have been updated. New fossil collections from the Big Bend National Park, Texas, allow for a much refined correlation

    Bhosale, Pradeep; Suryawanshi, Ashish; Mittal, Amber

    2012-01-01

    Background: Though Austin Moore (AM) replacement prosthesis has fairly good short term results for intracapsular femoral neck fractures in the elderly, it still is a compromised option and has a high failure rate in the long run. The objective of the present retrospective study is to analyze the functional outcome, assess survivorship of revision total hip arthroplasty (THA) at mid to long term followup, and evaluate intraoperative difficulties faced during conversion of failed aseptic AM prosthesis to cemented THA. Materials and Methods: Eighty-nine cemented THA surgeries for failed AM prosthesis were performed between 1986 and 2005. AM failures were classified into seven groups on the basis of mode of failure. Infected failures were excluded from the study. There were 35 men and 54 women in the study group. The mean age was 68 years (range 57–91 years). Mean followup was 8 years (range 5–13 years). Results: Average Harris Hip Score improved from 65 preoperatively (range 42–73) to 87 (range 76–90) at 1 year postoperatively and to 86 (range 75–89) at the last followup. The overall complication rate was 4.5%. Conclusion: Conversion THA is an excellent treatment strategy for symptomatic failed AM hemiarthroplasty in terms of pain relief and restoration of function and mobility as near as possible to the preinjury level. Also, hemiarthroplasty should not be used in physically active patients, even in elderly individuals. Careful patient selection for hemiarthroplasty versus THA is vital and may decrease the incidence of complications and ameliorate the outcomes in the treatment of intracapsular femoral neck fractures.

  8. Petrography and geochemistry of vein-filling calcites, balcones fault zone, upper cretaceous strata, north-central Texas

    1994-12-31

    The Austin Chalk and the underlying Eagle Ford Shale are transected by en echelon faults and fractures, associated with the Balcones Fault Zone, along an outcrop trend that extends from Dallas to Austin, Texas. These faults and fractures strike generally northeastward, and many are cemented by sparry calcite. Slickensides, preserved on outer surfaces of calcite cements, record fault movement. Early calcite cements are nonferroan, and later cements are ferroan calcite. Petrographic analyses indicate the occurrence of fir-tree zoning and fluorescent inclusions within calcite cements. Vein-filling cements have stable isotopic signatures {delta}{sup 18}O -5.7 to -9.8% PDB; {delta}{sup 13}C +1.6 to +2.7% PDB that are markedly depleted in {delta}{sup 18}O relative to the chalk matrix, inoceramid shells, and the estimated value for Cretaceous seawater. The depleted {delta}{sup 18}O signatures of the vein-filling calcites are suggestive of precipitation from warm basinal fluids. {delta}{sup 13}C analyses reveal that the Austin Chalk buffered the carbon incorporated into the calcite cements. These veins probably formed by a {open_quotes}crack-seal mechanism{close_quotes}, whereby episodic increases in hydropressure caused fracturing. Precipitation of calcite cements within fractures is induced by subsequent decreases in pore pressure. Tectonic and diagenetic features in these outcrops provide analogs for fractured Austin Chalk reservoirs.

    2011-06-30

    The Texas Hydrogen Education project builds on past interest in hydrogen and fuel cells to help create better informed leaders and stakeholders and thereby improve decision making and planning for inclusion of hydrogen and fuel cell technologies as energy alternatives in Texas. In past years in Texas, there was considerable interest and activities about hydrogen and fuel cells (2000-­‐2004). During that time, the Houston Advanced Research Center (HARC) created a fuel cell consortium and a fuel cell testing lab. Prior to 2008, interest and activities had declined substantially. In 2008, in cooperation with the Texas H2 Coalition and the State Energy Conservation Office, HARC conducted a planning process to create the Texas Hydrogen Roadmap. It was apparent from analysis conducted during the course of this process that while Texas has hydrogen and fuel cell advantages, there was little program and project activity as compared with other key states. Outreach and education through the provision of informational materials and organizing meetings was seen as an effective way of reaching decision makers in Texas. Previous hydrogen projects in Texas had identified the five major urban regions for program and project development. This geographic targeting approach was adopted for this project. The project successfully conducted the five proposed workshops in four of the target metropolitan areas: San Antonio, Houston, Austin, and the Dallas-­‐Ft. Worth area. In addition, eight outreach events were included to further inform state and local government leaders on the basics of hydrogen and fuel cell technologies. The project achieved its primary objectives of developing communication with target audiences and assembling credible and consistent outreach and education materials. The major lessons learned include: (1) DOE’s Clean Cities programs are a key conduit to target transportation audiences, (2) real-­‐world fuel cell applications (fuel cell buses, fuel cell

  10. The Dust Environment of Comet Austin 1990 V

    Fulle, M.; Bosio, S.; Cremonese, G.; Cristaldi, S.; Liller, W.; Pansecchi, L.

    1993-05-01

    We analyse 12 Schmidt plates concerning the dust tail of comet Austin 1990V taken at the Observatories of Catania, Cerro Tololo, ESO and Siding Spring during May and June, 1990. The absolute calibration of the images was performed by means of some standard fields of the Guide Star Photometric Catalogue I (Lasker et al. 1988) detected on the same plates containing the comet images. At the beginning of June the predicted Neck-Line Structure (Fulle & Pansecehi 1990) was detected and well observed as a streamer superimposed on the dust tail and an opposite sunward spike. We apply the inverse Monte- Carlo dust tail model (Fulle 1989) to two different sets of images, which provide results in reciprocal close agreement even if in the two sets the dust tail has a very different shape. We analyse dust grains of diameters between 10 μm and 10 cm ejected during the time interval -160 d < t < +60 d (days related to perihelion). The ejection velocity of millimeter-sized dust grains reaches its maximum value of 0.1 km s-1 at t = +10 d. The mass loss rate reaches a broad maximum of at least 3 l07 g s-1 a few days before perihelion. The power index of the time-averaged size distribution is -3.0±0.2. Strongly anisotropic dust ejections from the nucleus surface are incompatible with the observed shape of the dust tail. Further, the results of the photometry of the Neck-Line concerning the size dependence of the dust velocity and the observed length of the sunward spike indicate that the classical power index of the size dependence of the dust velocity u = -½ cannot account for all the observations. On the contrary, significantly higher index, u = -⅙, allows to reproduce very closely all the available data of the C/1990V dust tail. Also the size distribution and the mass loss rate given by the Neck- Line photometry agree with the results of the inverse Monte-Carlo model, thus supplying the first example of complete agreement between the two models. Although C/1990V was a new

    1982-07-01

    Problems in drilling and completing Texas wells with high-pressure gas and lower-pressure zones (where the mud system is lost into the pay zone) are described; wells that have a gas zone in the lower zone and oil zone in the upper; wells with an oil zone in upper and lower zones but with different gravity weight and color; and wells where high-pressure gas kicks are found in the upper zone and returns are lost in the lower. Topics include isolating the pay zone and cementing the liner. Whether to frac or acidize is determined by checking fractures, fluorescences, and gas shows. Goal is to reach the fault in the chalk.

    Over the past three years, McDonald Observatory has offered special Astronomy Day videoconference programs to students across Texas—the second largest state in the U.S. (Only Alaska is larger). Videoconferencing allows many students and teachers access to our Observatory, which is remotely located 180 miles (290 kilometers) from any major city. McDonald Observatory partners with Connect2Texas to advertise the Astronomy Day event. Connect2Texas provides the electronic bridge between schools and the Observatory. They also provide an online evaluation for teachers to complete. In 2009 the Astronomy Day videoconference celebrated the International Year of Astronomy and the historic observations made by Galileo Galilei. During the videoconference, the classes explore the Moon or Venus by making real-time telescopic observations. Students also receive an introduction to the Observatory, an opportunity to perform an activity relating to Galileo's observations, and an interview with an astronomer. A website provides teachers pre-and post-video conference materials, instructions, and a certificate of completion that can be customized for each student. The website also lists content alignment with state science education standards.

  3. Geology and geophysics of south-central Zavala and adjoining parts of Dimmit Counties, Texas

    Gravity, magnetic, and seismic surveys combined with subsurface geologic investigations resulted in very intriguing interpretations of an area east of Crystal City, Texas. The study area includes the south-central part of Zavala County east of the Nueces River and the adjoining parts of Dimmit County to the south. The Elaine field is included in the study area. Gravity and magnetic residuals were calculated using the least-squares method, and the magnetic surveys revealed several serpentine plugs, which are confirmed by seismic interpretations. Although no geophysics work was done, subsurface study shows that Elaine field is the largest of these plugs. Seismic studies also show that the Austin Chalk, on whose surface the lava was extruded, is highly fractured and faulted. The Austin under the Elaine field is the lowest structural feature in the area. The Anacacho was deposited on the lava surface, and in the Elaine area it has a reeflike appearance. Isopachs of younger sediments show that they are draped and differentially compacted over the plugs, and that the Elaine plug affects sediments as young as Escondido. Production in the area is mainly from the San Miguel, but significant amounts of hydrocarbons have also been produced from Eagle Ford, Austin, Anacacho, and Olmos reservoirs.

  7. Effective-stress-law behavior of Austin chalk rocks for deformation and fracture conductivity

    Warpinski, N.R.; Teufel, L.W.

    1994-08-01

    Austin chalk core has been tested to determine the effective law for deformation of the matrix material and the stress-sensitive conductivity of the natural fractures. For deformation behavior, two samples provided data on the variations of the poroelastic parameter, {alpha}, for Austin chalk, giving values around 0.4. The effective-stress-law behavior of a Saratoga limestone sample was also measured for the purpose of obtaining a comparison with a somewhat more porous carbonate rock. {alpha} for this rock was found to be near 0.9. The low {alpha} for the Austin chalk suggests that stresses in the reservoir, or around the wellbore, will not change much with changes in pore pressure, as the contribution of the fluid pressure is small. Three natural fractures from the Austin chalk were tested, but two of the fractures were very tight and probably do not contribute much to production. The third sample was highly conductive and showed some stress sensitivity with a factor of three reduction in conductivity over a net stress increase of 3000 psi. Natural fractures also showed a propensity for permanent damage when net stressed exceeded about 3000 psi. This damage was irreversible and significantly affected conductivity. {alpha} was difficult to determine and most tests were inconclusive, although the results from one sample suggested that {alpha} was near unity.

    Patterns of microearthquakes detected downhole defined fracture orientation and extent in the Austin chalk, Giddings field, TX and the 76 field, Clinton Co., KY. We collected over 480 and 770 microearthquakes during hydraulic stimulation at two sites in the Austin chalk, and over 3200 during primary production in Clinton Co. Data were of high enough quality that 20%, 31% and 53% of the events could be located, respectively. Reflected waves constrained microearthquakes to the stimulated depths at the base of the Austin chalk. In plan view, microearthquakes defined elongate fracture zones extending from the stimulation wells parallel to the regional fracture trend. However, widths of the stimulated zones differed by a factor of live between the two Austin chalk sites, indicating a large difference in the population of ancillary fractures. Post-stimulation production was much higher from the wider zone. At Clinton Co., microearthquakes defined low-angle, reverse-fault fracture zones above and below a producing zone. Associations with depleted production intervals indicated the mapped fractures had been previously drained. Drilling showed that the fractures currently contain brine. The seismic behavior was consistent with poroelastic models that predicted slight increases in compressive stress above and below the drained volume.

    Cogeneration is defined as the generation of electric power and coincident recovery of useful thermal energy from a single prime mover using a single fuel. The 1 MW gas turbine cogeneration system at Texas Department of Mental Health and Mental Retardation (TDMHMR), Austin, came on line in March, 1992 and is a unique application of federal and state funds. This system has been analyzed for its present performance and loads using hourly measured data. The Energy Systems Laboratory (ESL) at Texas A and M University has been collecting hourly data for natural gas use and the electrical energy produced by the engine since August, 1992. Waste heat recovered by the Waste Heat Recovery Boiler (WHRB) is also monitored. This paper describes the present system, analyzes the system using hourly monitored data, calculates energy and dollar savings, compares the measured results with the estimated savings, and discusses some of the problems encountered during the first year of operation.

    The transport system design and construction for The Texas Intense Positron Source (TIPS) facility has been completed. This facility is located on beam port 1 of The University of Texas at Austin TRIGA Mark II 1.1 MW research reactor. The TIPS will provide a high intensity, variable energy positron beam for use in material studies. The natural copper source is transported into beam port 1 of the reactor where it is irradiated at close proximity to the reactor core. The transport system is an L-shaped aluminum channel that utilizes pulleys to drive a source cart. The copper source is transported on the cart into and out of the beam port for irradiation. After removal from the beam port, the activated copper positron source will be placed into a vacuum chamber where the positrons are moderated with annealed tungsten foil and electrostatically extracted.

    The old diagnostic neutral beam injector first operated at the University of Texas at Austin is ready for rejoining the joint Texas experimental tokamak (J-TEXT). A new set of high voltage power supplies has been equipped and there is no limitation for beam modulation or beam pulse duration henceforth. Based on the spectra of fully striped impurity ions induced by the diagnostic beam the design work for toroidal charge exchange recombination spectroscopy (CXRS) system is presented. The 529 nm carbon VI (n = 8 - 7 transition) line seems to be the best choice for ion temperature and plasma rotation measurements and the considered hardware is listed. The design work of the toroidal CXRS system is guided by essential simulation of expected spectral results under the J-TEXT tokamak operation conditions. PMID:25430328

    Introduction Whether patterns of physical activity in different communities can be attributed to the built environment or instead reflect self-selection is not well understood. The objective of this study was to examine neighborhood preferences and behavior-specific physical activity among residents who moved to a new urbanist-designed community. Methods We used data from a 2009 survey (n = 424) that was designed and administered to evaluate neighborhood preferences and behavior-specific physical activity before and after residents moved. Data were grouped and stratified by pre-move physical activity levels into low-, middle-, and high-activity groups. We used Student’s paired sample t test and Wilcoxon signed-rank test to compare pre- and post-move scores and used an analysis of variance to compare mean changes as a function of pre-move physical activity level. Results After moving, the high-activity group continued to be significantly more active than the middle- and low-activity groups (P < .001). However, we saw the biggest increase in pre- to post-move total physical activity in the low-activity group (mean increase, 176.3 min/wk) compared with the middle- (mean increase, 69.5 min/wk) and high-activity groups (mean decrease, 67.9 min/wk). All 3 groups had significant increases in walking inside the neighborhood for recreation. The preferred neighborhood features with the most significant pre- to post-move change scores were those associated with greater walkability. Conclusion This study supports the role the environment plays in physical activity. These data suggest that moving to an activity-friendly neighborhood can positively affect physical activity levels, particularly among residents who had previously been least active. PMID:23786909

    There are no published reports of domestic or sylvatic trichinellosis in Texas. The aim of the present survey was to determine the presence of Trichinella species in selected representative species of potential wildlife reservoirs in southern Texas. In 1998-99, tongues of 211 wild mammals were collected in southern Texas: 154 coyotes (Canis latrans), three bobcats (Lynx rufus), 32 racoons (Procyon lotor), 13 opossum (Didelphis marsupialis), four ocelots (Leopardus pardalis) and five wild boars (Sus scrofa). Presence of Trichinella sp. larvae was investigated by artificial digestion and larvae of positive samples were identified at the species level by a multiple-polymerase chain reaction analysis. Nine (5.8%) coyotes had trichinellosis; in the muscles of seven of these coyotes, the larvae were identified as Trichinella murrelli. This is the first report of sylvatic trichinellosis in Texas.

    The Lower Cretaceous Pearsall Formation, a regionally occurring limestone and shale interval of 500-600-ft maximum thickness (Rose, 1986), is being evaluated as part of an ongoing U.S. Geological Survey (USGS) assessment of undiscovered hydrocarbon resources in onshore Lower Cretaceous strata of the northern Gulf of Mexico. The purpose of this report is to release preliminary vitrinite and bitumen reflectance, total organic carbon, and pyrolysis data for Pearsall Formation, Glen Rose Formation, Hosston Formation, Austin Group, and Eagle Ford Group samples from the Maverick Basin in south Texas in order to aid in the characterization of these strata in this area. The preliminary nature of this report and the data contained herein reflect that the assessment and characterization of these samples is a work currently in progress. Pearsall Formation subdivisions are, in ascending stratigraphic order, the Pine Island Shale, James Limestone, and Bexar Shale Members (Loucks, 2002). The Lower Cretaceous Glen Rose Formation is also part of the USGS Lower Cretaceous assessment and produces oil in the Maverick Basin (Loucks and Kerans, 2003). The Hosston Formation was assessed by the USGS for undiscovered oil and gas resources in 2006 (Dyman and Condon, 2006), but not in south Texas. The Upper Cretaceous Austin Group is being assessed as part of the USGS assessment of undiscovered hydrocarbon resources in the Upper Cretaceous strata of the northern Gulf of Mexico and, along with the Upper Cretaceous Eagle Ford Group, is considered to be an important source rock in the Smackover-Austin-Eagleford Total Petroleum System (Condon and Dyman, 2006). Both the Austin Group and the Eagle Ford Group are present in the Maverick Basin in south Texas (Rose, 1986).

    Kelly, Larry Joe

    This dissertation reports an exploration of one statewide case in the remarkable expansion of the American public high school in the early twentieth century. Specifically, it focuses on the curricula of early twentieth century secondary school system of the state of Texas. In particular, its development was shepherded, from 1886--1917, by the University of Texas. The vehicle was the university's program of affiliation with its approval of high schools in the state. Affiliation essentially was a system of accreditation of the state's high schools. It contributed the first systematic effort to provide guidance for the academic programs, teachers, and facilities for the state's rapidly developing high schools. A variety of social, political, and economic conditions affected the University's affiliation system. These conditions external and internal to the state constituted the formative circumstances for the development of secondary curricula in Texas. Mathematics, history, English, and Latin were the primary affiliated subjects during the late 1800's. Science offerings did not become affiliated subjects in the University of Texas affiliation program until the early 1900's. This study focused on the development and inclusion of science offerings in the curricula of affiliated high schools. It probed the nature and extent of the science course offerings in the growing number of affiliated Texas high schools. Its findings identify among other matters, the science courses that were offered in affiliated Texas high schools, textbooks used, and laboratory facilities. The involvement of The University of Texas at Austin in establishing high school curricular standards, the reconfiguration of the school day, the redesign of the curricula, the inspection and affiliation process, all provided standards for improvements in school districts that lacked effective state governmental guidance and supervision. This endeavor by the university, assumed by the State Department of

  12. A geospatial tool for wildfire threat analysis in central Texas

    Hunter, Bruce Allan

    Wildland fires in the United States are not always confined to wilderness areas. The growth of population centers and housing developments in wilderness areas has blurred the boundaries between rural and urban. This merger of human development and natural landscape is known in the wildland fire community as the wildland urban interface or WUI, and it is within this interface that many wildland fires increasingly occur. As wildland fire intrusions in the WUI increase so too does the need for tools to assess potential impact to valuable assets contained within the interface. This study presents a methodology that combines real-time weather data, a wildland fire behavior model, satellite remote sensing and geospatial data in a geographic information system to assess potential risk to human developments and natural resources within the Austin metropolitan area and surrounding ten counties of central Texas. The methodology uses readily available digital databases and satellite images within Texas, in combination with an industry standard fire behavior model to assist emergency and natural resource managers assess potential impacts from wildland fire. Results of the study will promote prevention of WUI fire disasters, facilitate watershed and habitat protection, and help direct efforts in post wildland fire mitigation and restoration.

    Launched in 2006, over 8,700 residential energy upgrades have been completed through Austin Energy's Home Performance with Energy Star (HPwES) program. The program's lending partner, Velocity Credit Union (VCU) has originated almost 1,800 loans, totaling approximately $12.5 million. Residential energy efficiency loans are typically small, and expensive to originate and service relative to larger financing products. National lenders have been hesitant to deliver attractive loan products to this small, but growing, residential market. In response, energy efficiency programs have found ways to partner with local and regional banks, credit unions, community development finance institutions (CDFIs) and co-ops to deliver energy efficiency financing to homeowners. VCU's experience with the Austin Energy HPwES program highlights the potential benefits of energy efficiency programs to a lending partner.

  20. Austin Chalk: cross-link gel water, slick water fracs common in Giddings field

    SciTech Connect

    1981-05-01

    Of the approx. 600 wells drilled in the Giddings field, Austin Chalk trend in the last year, most were probably completed by cross-link gel fracs or slick water fracs. Although open hole completions are not uncommon in the chalk, they are not really practical in most situations, given the 600 to 800 ft of gross pay usually encountered in the Austin Chalk trend. Most of the open hole completions occur when an operator takes a kick while drilling and decides to drop a mud pill over the zone, run casing above it, cement it in and produce the interval open hole. Chalk wells are subject to kick at any time during drilling because of natural fracturing systems throughout the trend. Mud weights are generally fairly light for faster drilling, approx. 9.4 to 9.8 lb, depending on the particular area.

    Spectroscopic observations of Comet Austin (1989c1) at millimeter wavelengths are reported. The rotational transitions of hydrogen cyanide and formaldehyde were detected. Hydrogen sulfide and methanol, neither of which has previously been detected in a comet, were identified. The presence of hydrogen sulfide places severe constraints on the formation of cometary nuclei, whereas that of methanol supports the hypothesis that cometary nuclei have retained, at least in part, some primitive material originating from the solar nebula.

    Home Performance with ENERGY STAR (HPwES) is a jointly managed program of the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). This program focuses on improving energy efficiency in existing homes via a whole-house approach to assessing and improving a home's energy performance, and helping to protect the environment. As one of HPwES's local sponsors, Austin Energy's HPwES program offers a complete home energy analysis and a list of recommendations for efficiency improvements, along with cost estimates. To determine the benefits of this program, the National Renewable Energy Laboratory (NREL) collaborated with the Pacific Northwest National Laboratory (PNNL) to conduct a statistical analysis using energy consumption data of HPwES homes provided by Austin Energy. This report provides preliminary estimates of average savings per home from the HPwES Loan Program for the period 1998 through 2006. The results from this preliminary analysis suggest that the HPwES program sponsored by Austin Energy had a very significant impact on reducing average cooling electricity for participating households. Overall, average savings were in the range of 25%-35%, and appear to be robust under various criteria for the number of households included in the analysis.

  20. Seismicity of west Texas

    SciTech Connect

    Dumas, D.B.

    1981-01-01

    A four year seismic study has found the Basin and Range province of west Texas and the adjacent area of Mexico to be more seismically active then than heretofore known. A University of Texas five station seismic array around the Marfa Basin has located or detected approximately 800 local and regional earthquakes with S-P times of less than 30 sec. A crustal model for the Basin and Range is derived from natural and artificial sources and contains four layers having velocities of 3.60, 4.93, 6.11, and 6.60 km/sec, respectively, overlying a mantle of 8.37 km/sec. A moderate level of seismic activity has been detected near Van Horn, in the Marfa Basin, and along the Texas-Mexico border between latitudes 30 and 31/sup 0/N. Five earthquake sequences were recorded, two near the Texas-Mexico border and three in the Marfa Basin. Four of these sequences showed quiescent periods in foreshock activity preceding the main shock. On the eastern side of the Marfa Basin a diffuse linear seismic zone may represent an unmapped fault, striking N 50/sup 0/W that coincides with Muehlberger's proposed eastern boundary of Basin and Range faulting. A new epicenter for the Valentine, Texas earthquake of August 16, 1931 has been relocated instrumentally at the northern end of this diffuse zone. Regional and local teleseismic P-wave arrival time anomalies observed for the nearby Gnome underground nuclear explosion of 1961 are used to determine station corrections and thus to locate the new 1931 epicenter at 3.69/sup 0/N, 104.57/sup 0/W. Several estimates of magnitude (m/sub b/) based on intensity data range from 5.6 to 6.4. Fault-plane and composite fault-plane solutions support Muehlberger's hypothesis that the Basin and Range is undergoing extension in a SW-NE direction.

  1. Catalogue of Texas spiders.

    This catalogue lists 1,084 species of spiders (three identified to genus only) in 311 genera from 53 families currently recorded from Texas and is based on the "Bibliography of Texas Spiders" published by Bea Vogel in 1970. The online list of species can be found at http://pecanspiders.tamu.edu/spidersoftexas.htm. Many taxonomic revisions have since been published, particularly in the families Araneidae, Gnaphosidae and Leptonetidae. Many genera in other families have been revised. The Anyphaenidae, Ctenidae, Hahniidae, Nesticidae, Sicariidae and Tetragnathidae were also revised. Several families have been added and others split up. Several genera of Corinnidae were transferred to Phrurolithidae and Trachelidae. Two genera from Miturgidae were transferred to Eutichuridae. Zoridae was synonymized under Miturgidae. A single species formerly in Amaurobiidae is now in the Family Amphinectidae. Some trapdoor spiders in the family Ctenizidae have been transferred to Euctenizidae. Gertsch and Mulaik started a list of Texas spiders in 1940. In a letter from Willis J. Gertsch dated October 20, 1982, he stated "Years ago a first listing of the Texas fauna was published by me based largely on Stanley Mulaik material, but it had to be abandoned because of other tasks." This paper is a compendium of the spiders of Texas with distribution, habitat, collecting method and other data available from revisions and collections. This includes many records and unpublished data (including data from three unpublished studies). One of these studies included 16,000 adult spiders belonging to 177 species in 29 families. All specimens in that study were measured and results are in the appendix. Hidalgo County has 340 species recorded with Brazos County at 323 and Travis County at 314 species. These reflect the amount of collecting in the area. PMID:27103878

  4. Vein-filling calcites (petrography and geochemistry): Balcones fault zone, Upper Cretaceous outcrops, north-central Texas

    1994-09-01

    The Austin Chalk and the underlying Eagle Ford Shale are transacted by en echelon faults and fractures, associated with the Balcones fault zone, along an outcrop trend that extends from Dallas to Austin, Texas. These faults and fractures strike northeastward (N35{degrees} to 40{degrees}E) and are cemented by multiple generations of sparry calcite. Vein widths range from 0.1 to 45 cm. Slickensides, preserved on outer surfaces of calcite cements, record fault movement. Inclusions of country rock are present within calcite-filled veins, and rarely, open fracture porosity is observed in outcrop. Early calcite cements are nonferroan and later cements are ferroan calcite. Petrographic analyses indicate the occurrence of {open_quotes}fir-tree{close_quotes} zoning and fluorescent inclusions within calcite cements. Vein-filling cements have stable isotopic signatures ({delta}{sup 18}O-6.3 to -9.8{per_thousand} PDB; {delta}{sup 13}C +1.6 to +2.5{per_thousand} PDB) that are markedly depleted in {delta}{sup 13}O relative to the chalk matrix, inoceramid shells, and the estimated value for Cretaceous seawater. Trace element analyses indicate the presence of strontium (980-1600 ppm), manganese (750-1975 ppm), zinc (10-20 ppm), and copper (5-10 ppm) in the calcite cements. The negative {delta}{sup 18}O signatures of the vein-filling calcites are suggestive of precipitation from warm fluids. {delta}{sup 13}C analyses reveal that the Austin Chalk buffered the carbon incorporated into the calcite cements. These veins probably formed by a {open_quotes}crack-seat mechanism{close_quotes} whereby episodic increases in hydropressure caused fracturing. Precipitation of calcite cements within fractures is induced by subsequent decreases in pore pressure. Tectonic and diagenetic features in these outcrops provide analogs for fractured Austin Chalk reservoirs.

  6. Medicolegal hell in Texas.

    Korcok, M

    1995-10-01

    In the "war zones" of Texas, lawyers use billboards, television commercials and Yellow Page advertisements to announce their availability to help the "unjustly injured," and medicolegal lawsuits are as common as the rain that sweeps in from the nearby Gulf of Mexico. Almost 75% of the suits are dismissed without award or settlement, since many are plainly frivolous. However, even these can mean torment for physicians, who have to hire lawyers, answer charges, collect paperwork, take time off work for depositions and consultations, and then worry about how insurers will react the next time premiums are due--even if they are cleared. Texas estimates that defensive medicine practised because of legal fears costs the state at least $702 million annually, spending that is bound to continue as long as one lawsuit is filed annually for every 5.3 doctors in the state.

    Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

    The aim of this paper is to show how "conceptual analysis"-the philosophical method used by Gilbert Ryle and John Austin-can contribute to behavior analysis in general and in particular to the elucidation and development of views put forward by B. F. Skinner. One of the key requirements is a sensitivity to the precise circumstances in which particular combinations of words are uttered. Without such sensitivity, it is difficult to make informed decisions as to when ways of talking should be changed and when they should be left as they are. PMID:22478170

    The appearance of the bright comet Austin 1989c1 in April-May of 1990 allowed us to test a new imaging instrument at the Joint Observatory for Cometary Research (JOCR). It is a 300mm lens/charge coupled device (CCD) system with interference filters appropriate for cometary emissions. The 13 frames were made into a time-lapse movie showing the evolution of the plasma tail. We were able to follow at least two large-scale waves out through the main tail structure. During the sequence, we saw two new tail rays form and undergo similar wave motion.

    Comet Okazaki-Levy-Rudenko (1989r) was studied over a wide range of wavelengths from the UV to the submillimeter. Using visual magnitude estimates from the IAU Circulars and reported submillimeter fluxes in conjunction with the thermal infrared spectroscopy and filter photometry, the nature of the grains and the behavior of the comet can be assessed and compared to other comets studied under this program. In addition, preliminary results from a collaborative infrared study of Comet Austin are presented which address the nature of the dust in that comet. Progress on a model for cometary properties and brightness behavior is discussed.

  14. Record Rainfall and Flooding in Texas and Oklahoma, May 2015; Extent and Historical Perspective

    Cepeda, J. C.

    2015-12-01

    Heavy rains began in Texas and Oklahoma in early May 2015 and continued through the end of the month. Both states set all-time records for mean statewide precipitation; Texas - 227mm (8.93 in), Oklahoma - 357mm (14.06 in) -- for the period of record (1895-2015). These new statewide records were set despite the fact that the western portions of both Texas and Oklahoma received only modest rainfall. Parameters used in this study to evaluate the magnitude and historical perspective of the May 2015 rainfall included daily and total storm precipitation, stream flow, changes in the Palmer Drought Severity Index (PDSI), and changes in reservoir water levels. Although the Dallas-Fort Worth area and the cities of Austin, Houston and Oklahoma City sustained the most serious flood events, more than 100 localities in the two states reported some flooding. The region with the largest amounts of precipitation extended from north-central Texas northeastward into eastern Oklahoma. Cumulative May rainfall in this region exceeded 508 mm (20 in). Provisional stream flow data for the river basins most affected -- Red River, Brazos, Colorado, and Trinity rivers -- reveal significant peaks, but the peaks generally are within the ranges of the historical record. With the exception of the Red River the most significant flooding relative to historic flood peaks, occurred on tributaries to the major rivers. Comparison of the PDSI for the months of April and June reveals the dramatic impact of the precipitation during May. By the first week of June both states are classified as moderately moist - with the exception of the extreme northeastern corner of Oklahoma. Changes in Reservoir levels (as a percent of capacity) between April and June was greatest for the Rolling Plains region (+ 15.5%), with lesser, but significant gains in South and Central Texas and the Central Oklahoma region.

    After eight years of singular effort, the UT-TRIGA Mark II research reactor was licensed and is fully operational. This reactor is the focus of a new reactor laboratory facility which is located at the Balcones Research Center, a north Austin campus of The University of Texas at Austin. The UT-TRIGA reactor is licensed for 1.1 MW steady power operation and 3 dollar pulsing. A startup program was implemented upon receipt of the facility license on January 17, 1992. Several facility features are unique to this startup. Among these were the use of fuel with various burnup and a digital control system. The reactor laboratory staff with assistance from a General Atomics instrumentation engineer performed all phases of the startup program. Core loading began in February 1992 with final testing completed in May 1992. Several unusual problems were encountered during this time. Experiment authorizations have been written to resume Neutron Activation Analysis programs and isotope production. Several neutron beam tube experiments are in the design and test phase. (author)

    A new strategy of multi-objective structural optimization is integrated into Austin-Moore prosthesis in order to improve its performance. The new resulting model is so-called Improved Austin-Moore. The topology optimization is considered as a conceptual design stage to sketch several kinds of hollow stems according to the daily loading cases. The shape optimization presents the detailed design stage considering several objectives. Here, A new multiplicative formulation is proposed as a performance scale in order to define the best compromise between several requirements. Numerical applications on 2D and 3D problems are carried out to show the advantages of the proposed model. PMID:27028554

    A Neutron Depth Profiling (NDP) facility has been developed at The University of Texas at Austin (UT) Nuclear Engineering Teaching Laboratory. Thermal neutrons from the tangential beam port of the UT 1-MW TRIGA Mark II research reactor are utilized. The UT-NDP facility consists of a neutron beam collimator, target chamber, beam catcher, and necessary data acquisition and process electronics. The collimator was designed to achieve a high quality thermal neutron beam with good intensity and minimum contamination of neutrons above thermal energies. A target chamber for NDP was constructed from 40.6 cm diameter aluminum tubing. The chamber can accommodate several small samples as well as a single large sample with a diameter up to 30.5 cm. Depth profiles for borophosphosilicate glass films on silicon wafers were measured using the UT-NDP facility. Other potential applications of the UT-NDP facility include the study of implanted boron in semiconductor material; study of nitrogen in metals; and study of helium behavior in metals, and metallic and amorphous alloys.

    The Center for Electromechanics at the University of Texas at Austin (CEM-UT) presently has five experimental electromagnetic (e.m.) launchers or railguns in operation. An additional ten fully operational railguns are presently decommissioned and five new launchers are being fabricated. Several different parallel rail configurations and geometries are being studied as well as augmented rails and coaxial launchers. Recent tests utilizing the magnetic flux generated in a coil have produced promising results for work with coilgun launchers. Electromagnetic launchers at CEM-UT have been used in a wide variety of experiments. Particles of 50-500 μm in diameter have been accelerated up to 11 km/s to determine the effects of micrometeorite impacts on materials used in space applications and 2.5-kg packages have been launched to 2.6 km/s (8.1 MJ muzzle energy) in ballistic tests. Paper studies on launching 100-kg payloads at 10 km/s have also been conducted to determine the feasibility of launching satellites with e.m. launchers.

    1995-07-10

    The supervisory control and data acquisition (scada) system along Aquila Gas Pipeline`s more than 2,000-mile system evolved without a controlling plan over the last 14 years to become, nonetheless, workable and effective. The old system operated at about 20 bits per sec (bps), monitoring 210 points and taking a complete poll in 20 min. Although this system served the company well, in 1991 the company bought another pipeline and agreed to sell gas to a power plant. This change involved adding two new highly automated metering stations that required a more sophisticated remote terminal unit (RTU). To fulfill this need, two Fisher remote operating controllers (ROCs) were purchased. The vendor also provided three more to be tried as electronic flow meters. Meanwhile, horizontal drilling arrived in the Central Texas Austin Chalk oil field, prompting rapid expansion. Sales of natural gas increased from 60 MMcfd in 1991 to more than 300 MMcfd in 1994. The pipeline network increased from 1,200 miles in 1991 to more than 2,000 miles in 1994. Telemetering stations increased from 35 to 62, and requirements for speed and accuracy changed drastically. Two new requirements were remote operation of block valves and control valves. The paper describes the pipeline`s evolution.

  11. Hyporheic Flow and Heat Transport Within a Bed-to-Bank Transect of a Large Regulated River: Colorado River, Austin, TX

    NASA Astrophysics Data System (ADS)

    Gerecht, K.; Cardenas, B.; Guswa, A. J.; Sawyer, A. H.; Swanson, T.; Nowinski, J. D.

    2010-12-01

    The stage and discharge of the Lower Colorado River (LCR) near Austin, Texas is regulated by a series of dams for hydropower generation, flood management, water supply, and recreation. Daily releases from a dam, 23 km upstream of the study site, cause the stage at the site to fluctuate by more than 1.5 m with a mean depth of 1.3 m. These fluctuations cause the LCR at the study site to transition from a regionally gaining river to a river that both gains and loses over each daily cycle. To assess the effects of the flow management on river-groundwater exchange, we collected temperature and head measurements across a hyporheic-to-riparian transect that were highly resolved in both space and time over two campaigns of three days each. These observations show that river-groundwater exchange flux is consistently larger close to the bank and decreases with distance from the bank. Correspondingly, both the depth of the hyporheic zone and the exchange time are greatest near the bank. Adjacent to the bank streambed head response is hysteretic, with hysteresis dissipating with increased distance from the bank, indicating that transient bank storage affects the direction and magnitude of vertical exchange close to the bank. Hyporheic zone temperature is perturbed up to one meter below the bed. When the river stage is high, which coincides with when the river is coldest, downward advection of heat from a previous cycles’ warm-water pulse warms the hyporheic zone. When the river is at its lowest stage but warmest temperature, upwelling groundwater cools the hyporheic zone. These hydraulic and thermal alterations may change the biogeochemical and ecologic dynamics of the river and its hyporheic and riparian zones, including the hyporheic zone’s capacity to act as a biological filter and habitat.

    1991-03-01

    The SSC, a large (54 mi, or 87 km, in circumference) scientific instrument designed to accelerate, guide, and focus opposing beams of protons around an oval bedrock tunnel to collision, will be located near Waxahachie in northern Ellis County, Texas. Construction of the collider tunnel will involve excavation of three Upper Cretaceous rock bodies. From oldest to youngest, these are the Eagle Ford, Austin, and Taylor groups. Approximately 70% of the tunnel will traverse the 500-ft-thick (153-m) Austin Chalk. The site lies along the northeastward extension of the central Texas Balcones fault system, a zone of inactive, en echelon normal faults. In the SSC vicinity, most faults are generally straight to broadly curving and strike northeast to east-northeast. Dips of the larger faults range from 45{degree} to 80{degree} northwest or southeast. Displacements of the large faults range up to an estimated 100 ft (30 m). Some of the faults bound small, northeastward-trending grabens that are more than 2000 ft (610 m) wide and 3.5 mi (5.5 km) long. Features associated with the faults include (1) low (relief up to 40 ft, or 12 m) resequent fault-line scarps, (2) normal and reverse drag with strata inclined more than 40{degree} at places, (3) crystalline calcite fracture fillings with slickensides preserved on the outer surfaces of the fillings, and (4) broad (up to 1 mi, or 1.6 km, wide), northward-trending flexures that occur at some places. Joints present in the SSC vicinity are nearly vertical and usually reflect the local structure. Most structural features exposed along the collider path developed in response to sediment loading in the Gulf basin; the imposed stresses resulted in rotation and possible sliding of a large stratal mass gulfward.

  17. Geologic models and evaluation of undiscovered conventional and continuous oil and gas resources: Upper Cretaceous Austin Chalk

    USGS Publications Warehouse

    Pearson, Krystal

    2012-01-01

    The Upper Cretaceous Austin Chalk forms a low-permeability, onshore Gulf of Mexico reservoir that produces oil and gas from major fractures oriented parallel to the underlying Lower Cretaceous shelf edge. Horizontal drilling links these fracture systems to create an interconnected network that drains the reservoir. Field and well locations along the production trend are controlled by fracture networks. Highly fractured chalk is present along both regional and local fault zones. Fractures are also genetically linked to movement of the underlying Jurassic Louann Salt with tensile fractures forming downdip of salt-related structures creating the most effective reservoirs. Undiscovered accumulations should also be associated with structure-controlled fracture systems because much of the Austin that overlies the Lower Cretaceous shelf edge remains unexplored. The Upper Cretaceous Eagle Ford Shale is the primary source rock for Austin Chalk hydrocarbons. This transgressive marine shale varies in thickness and lithology across the study area and contains both oil- and gas-prone kerogen. The Eagle Ford began generating oil and gas in the early Miocene, and vertical migration through fractures was sufficient to charge the Austin reservoirs.

  10. A geological assessment: What`s ahead for Louisiana Austin chalk

    SciTech Connect

    Maloy, W.T.

    1997-06-02

    Both noteworthy and recent, the extension of the Austin chalk horizontal drilling play into Louisiana has been as closely watched as it has been controversial. The play has been controversial for the critics who claim the Louisiana chalk boom is simply the latest chapter in the chalk`s boom and bust history. The play is closely watched by chalk enthusiasts who have seen Louisiana horizontal wells yield as much as 80,000 bbl of oil and 250 MMcf of gas in a single month. Who is right? How will the play develop? This article presents a geological assessment of the play and offers some insights into the future of horizontal drilling in Louisiana.

  11. A possible detection of infrared emission from carbon monoxide in Comet Austin (1989c1)

    NASA Technical Reports Server (NTRS)

    Disanti, Michael A.; Mumma, Michael J.; Lacy, John H.; Parmar, Parvinder

    1992-01-01

    A cryogenic IR echelle grating spectrometer has been used to probe the nu = 1-0 rovibrational band of the CO molecule in Comet Austin. Line emission has been detected at the Doppler-shifted frequency expected for the cometary P(3) line, in scans which are noted to cover only the first 3000 sec of May 16, 1990 observations; this is suggested to be due to an outburst of comparable duration. No detections were made of the P(2) line, which was predicted by models to occur at the 3.5 sigma level even for relatively high coma temperatures. If the outburst was accompanied by enhanced dust production, an increase by a factor of 2.5 is consistent with the present observational data and CO/dust may have been enriched in the outbursting volume relative to the remainder of the nucleus.

  12. Lightcurve of comet Austin(1989c1) and its dust mantle development

    NASA Technical Reports Server (NTRS)

    Hasegawa, Hitoshi; Watanabe, Jun-Ichi

    1992-01-01

    Brightness variations of comet Austin(1989c1) were investigated in terms of the variations of water production rate. We translated the visual brightness data into water production rates using Newburn's semi-empirical law. The curve of the water production rates as a function of heliocentric distance was compared with the model calculations that assumed energy balance between the solar incident and vaporization of water. Thermal flow in a dust mantle at a surface of the nucleus is also included in the model. The model calculations including the dust mantle are more favorable for the observed rate than non-dust mantle cases. The extinction after the perihelion passage suggests that the dust mantle developed gradually.

    Reeve, R.P.; Peters, E.J.

    1982-01-01

    An economic evaluation has been performed to determine the expected returns on investment for a drilling program in the Giddings, Austin Chalk gas field. Using projected production schedules of selected well types from the encountered reserve distribution, computer based cashflow analyses were performed under 6 hypothesized future scenarios of varying hydrocarbon pricing, demand, taxation, and inflation. For the 6 future scenarios studied, the Giddings gas field drilling program was found to produce a positive, after tax net present value, using 15% as a discount factor. Furthermore, the returns on investment were higher for an independent than for a major producer. The results suggest a drilling program initiated in the near future will prove to be an attractive economic venture. 15 references.

  20. Perspectives and Challenges for Water Desalination - A Socio-Economic Multi-Regional Analysis and a Case Study for Texas

    NASA Astrophysics Data System (ADS)

    Ziolkowska, J. R.; Scanlon, B. R.; Young, M.

    2013-12-01

    Water desalination is anticipated to become a prospective solution for mitigating future water shortages in Texas. As of 2010, 46 municipal brackish water desalination plants were operating in Texas with an estimated total desalination capacity of about 120 million gallons per day (2.3% of state water use) (TWDB 2010; TWDB 2013). In 2011, 99% of the State of Texas suffered extreme drought, with large portions suffering through exceptional drought. This event was classified as the one-year drought of record. Moreover, the growing population of Texas and the subsequent growing water demand create an immediate need for long-term planning for a reliable and efficient water supply. Desalination, even though acknowledged as a reliable option in many countries in the world, requires high investment costs and energy inputs. Current costs of desalinated water can range between US1.09/1,000 gallons and US3.7/1,000 gallons (Arroyo and Shirazi 2012), which are about two to three times higher than water costs from conventional sources (San Antonio Water System 2012; AustinTexas.gov 2013). Economic efficiency is still the main factor determining future developments of desalination investments in Texas, and the technology is still emerging. While currently only investment, maintenance and total capital costs per unit water are considered as factors determining viability of a desalination plant, this study aims at depicting a broader picture of socio-economic impacts related to the construction project itself, both in the immediate region and adjacent communities and interlinked sectors. This study presents an Input-Output model for the brackish water desalination plant in San Antonio, with the first stage expected to be completed in 2016. By using multi-regional and sectoral multipliers, the analysis shows that constructing the desalination plant can create 2,050 jobs in the San Antonio region, while it will add 316 more jobs in other regions in Texas by 2016. Construction will

    2003-12-01

    The University of Texas at Austin Institute for Geophysics (UTIG) is engaged in six K-12 education and outreach programs, including two NSF-sponsored projects--GK-12: Linking Graduate Fellows with K-12 Students and Teachers and Cataclysms and Catastrophes--Texas Teachers in the Field, Adopt-a-School, Geoscience in the Classroom, and UT's Science and Engineering Apprenticeship Program. The GK-12 Program is central to UTIG's effort and links the six education projects together. While the specific objectives of each project differ, the broad goals of UTIG's education and outreach are to provide high-quality professional development for teachers, develop curriculum resources aligned with state and national education standards, and promote interaction between teachers, scientists, graduate students, and science educators. To achieve these goals, UTIG has forged funded partnerships with scientific colleagues at UT's Bureau of Economic Geology, Marine Science Institute and Department of Geological Sciences; science educators at UT's Charles A. Dana Center and in the Department of Curriculum and Instruction in the College of Education; teachers in six Texas independent school districts; and 4empowerment.com, a private education company that established the "Cyberways and Waterways" Web site to integrate technology and education through an environmentally-based curriculum. These partnerships have allowed UTIG to achieve far more than would have been possible through individual projects alone. Examples include the development of more than 30 inquiry-based activities, hosting workshops and a summer institute, and participation in local science fairs. UTIG has expanded the impact of its education and outreach and achieved broader dissemination of learning activities through 4empowerment's web-based programs, which reach ethnically diverse students in schools across Texas. These partnerships have also helped UTIG and 4empowerment to secure additional funding for other education

    Current statistical methods may be unable to accurately predict recurrence intervals of rare, large-magnitude floods, especially in semiarid regions having positively skewed annual flood distributions, great hydrologic variability, and widely spaced gaging stations. Current approaches rely on historical data, but catastrophic floods may have recurrence intervals far greater than the length of historical records. In the lower Pecos and Devils Rivers of southwestern Texas, paleoflood discharge and frequency estimates are extended over 10,000 years by the study of slack-water flood sediments. Slack-water deposits are typically fine-grained sand and silt that accumulate during floods in areas where current velocity is reduced, i.e., in back-flooded tributary mouths, channel expansions, downstream from bedrock spurs and/or slump blocks, and in shallow caves along bedrock walls. Radiocarbon dating of organic detritus in slack-water deposits establishes the flood chronology while paleoflood discharges can be estimated by slope-area techniques. Paleoflood information extracted from slack-water sediments can greatly extend flood records. These floods may be weighted like historical data in log Pearson type 3 calculations of flood frequency. Our morphostratigraphic approach combines recorded data with geomorphic evidence to derive estimates of flood frequency. This technique offers an inexpensive and rapid way to assess catastrophic flood risk.

    2003-06-01

    In the spring of 2002, the Department of Energy provided an initial 1-year grant to the Bureau of Economic Geology (BEG) at The University of Texas at Austin (UT). The grant covered the one-year operational expenses of a worldclass core and cuttings facility located in Houston, Texas, that BP America donated to the BEG. The DOE investment of $300,000, matched by a $75,000 UT contribution, provided critical first-year funds that were heavily leveraged by the BP gift of $7.0 million in facilities and cash. DOE also provided a one-month extension and grant of $30,000 for the month of May 2003. A 5-year plan to grow a permanent endowment in order to manage the facility in perpetuity is well under way and on schedule. The facility, named the Houston Research Center, represents an ideal model for a strong Federal, university, and private partnership to accomplish a national good. This report summarizes the activities supported by the initial DOE grant during the first 13 months of operation and provides insight into the activities and needs of the facility in the second year of operation.

    Shell Oil Company donated its proprietary core and sample repository to the Bureau of Economic Geology, The University of Texas at Austin, in 1994. This collection of geologic materials is composed of 325,000 boxes of rocks and samples housed in a 32,700-ft{sup 2} warehouse in Midland, Texas. The material includes cores from more than 3,000 wells (75,000 boxes) and cuttings from more than 90,000 wells (260,000 boxes). In addition to the warehouse space, the repository consists of layout rooms, a processing room, and office space. The U.S. Department of Energy provided $375,000 under Grant Number DE-FG22-94BC14854 for organizing the collection, staffing the facility, and making the material available to the public for the first 5 years of operation. Shell Oil Company provided an endowment of $1.3 million to cover the cost of operating the facility after the fifth year of operation.

  6. New Ulm field: an example of Cretaceous shelf-slope instability in east Texas

    SciTech Connect

    Pinero, E.

    1984-04-01

    The New Ulm field in Austin County, Texas, is an example of the structural and stratigraphic complexity above the Cretaceous Edwards shelf margin of east Texas. Deep wells and improved seismic data provide documentation of structural patterns and deepwater facies not previously considered in the Gulf Coast reservoir play modeling. Study of the data implies the Late Cretaceous to Eocene section was deposited along a shelf-slope break. Late Cretaceous, pre-Midway sedimentation was affected by structurally induced slope instability, and consequent gravity faulting and slumping resulted in an irregular sea-floor surface. Paleocene Midway sands were carried onto this surface by storm-generated density currents where the uneven topography caused deposition in constructional channels. Continued deposition of the fluvio-deltaic Wilcox on this surface caused faulting and folding by differential compaction. The folds are minor and the faults small and steep, not like the typical large growth faults of the Gulf Coast. Upper Wilcox sediments were progressively less disturbed as the region stabilized. New Ulm field production includes gas from the Midway Formation and oil and gas from the Wilcox Group. Midway reservoirs are stratigraphic, consisting of fluvio-deltaic sandstones within faulted anticlines. This study adds evidence to data describing shelf-slope geology along the Edwards margin. The setting can be a new type of hydrocarbon play in the Gulf Coast.

    Pair plasmas and intense gamma-ray sources are ubiquitous in the high-energy universe, from pulser winds to gamma-ray bursts (GRB). Their study can be greatly enhanced if such sources can be recreated in the laboratory under controlled conditions. In 2012 and 2013, a joint Rice-University of Texas team performed over 130 laser shots on thick gold and platinum targets using the 100 Joule Texas Petawatt Laser in Austin. The laser intensity of many shots exceeded 1021 W.cm-2 with pulses as short as 130 fs. These experiments probe a new extreme regime of ultra-intense laser - high-Z solid target interactions never achieved before. In addition to creating copious pairs with the highest density (>1015/cc) and emergent e +/e- ratio exceeding 20% in many shots, these experiments also created the highest density multi-MeV gamma-rays, comparable in absolute numbers to those found inside a gamma-ray burst (GRB). Potential applications of such intense pair and gamma-ray sources to laboratory astrophysics and innovative technologies will be discussed. Work supported by DOE HEDLP program.

    The reduction of the precipitation depth from a design storm for a point to an effective (mean) depth over a watershed often is important for cost-effective design of hydraulic structures by reducing the volume of precipitation. A design storm for a point is the depth of precipitation that has a specified duration and frequency (recurrence interval). The effective depth can be calculated by multiplying the design-storm depth by an areal-reduction factor (ARF). ARF ranges from 0 to 1, varies with the recurrence interval of the design storm, and is a function of watershed characteristics such as watershed size and shape, geographic location, and time of year that the design storm occurs. This report documents an investigation of ARF by the U.S. Geological Survey, in cooperation with the Texas Department of Transportation, for the 1-day design storm for Austin, Dallas, and Houston, Texas. The ?annual maxima-centered? approach used in this report specifically considers the distribution of concurrent precipitation surrounding an annual precipitation maxima. Unlike previously established approaches, the annual maxima-centered approach does not require the spatial averaging of precipitation nor explicit definition of a representative area of a particular storm in the analysis. Graphs of the relation between ARF and circular watershed area (to about 7,000 square miles) are provided, and a technique to calculate ARF for noncircular watersheds is discussed.

  9. Texas Solar Collaboration DOE Rooftop Solar Challenge City of Houston Project Summary

    The City of Houston is committed to achieving a sustainable solar infrastructure. In 2008, Houston was named a United States Department of Energy (DOE) Solar America City. As a Solar America City, Houston teamed with the Houston Advanced Research Center (HARC), Sandia National Laboratory (Sandia), industry, and academia, to implement the Solar Houston Initiative and prepare the Solar Houston Plan. The Solar Houston initiative was focused on identifying and overcoming barriers associated with establishing a solar infrastructure that is incorporated into the City of Houston’s overall energy plan. A broad group of Houston area stakeholders, facilitated by HARC, came together to develop a comprehensive solar plan that went beyond technology to address barriers and establish demonstrations, public outreach, education programs and other activities. The plan included proposed scopes of work in four program areas: policies, solar integration, public outreach, and education. Through the support of the DOE SunShot Rooftop Solar Challenge (RSC) grant to the Texas Collaboration (San Antonio, Austin, and Hosuton), Houston has been able to implement several of the recommendations of the Solar Houston Plan. Specific recommendations that this project was able to support include; Working with the other Texas Solar America Cities (San Antonio and Austin), to harmonize permitting and inspection processes to simplify for installers and lower soft costs of installation; Participating in state level solar policy groups such as the Texas Renewable Energy Industries Association (TRIEA); Continued coordination with the local transmission and distribution utility (CenterPoint) and retail electric providers (REP); Identification of opportunities to improve permitting and interconnection; Providing training on PV systems to City inspectors; Educating the public by continuing outreach, training, and workshops, particularly using the the Green Building Resources Center; Evaluating methods of

  10. The solar wind structure that caused a large-scale disturbance of the plasma tail of comet Austin

    The plasma tail of Comet Austin (1989c1) showed remarkable disturbances because of the solar maximum periods and its orbit. Figure 1 shows photographs of Comet Austin taken in Shibata, Japan, on 29 Apr. 1990 UT, during about 20 minutes with the exposure times of 90 to 120 s. There are two main features in the disturbance; one is many bowed structures, which seem to move tailwards; and the other is a large-scale wavy structure. The bowed structures can be interpreted as arcade structures brushing the surface of both sides of the cometary plasma surrounding the nucleus. We identified thirteen structures of the arcades from each of the five photographs and calculated the relation between the distance of each structure from the cometary nucleus, chi, and the velocity, upsilon. The result is shown. This indicates that the velocity of the structures increases with distance. This is consistent with the result obtained from the observation at the Kiso Observatory.

    Vitrinite reflectance measurements were made to determine the rank of selected subsurface coal and coaly shale samples from Young County, north-central Texas, for the National Coal Resources Database System State Cooperative Program conducted by the Bureau of Economic Geology at The University of Texas at Austin. This research is the continuation of a pilot study that began in adjacent Archer County, and forms part of a larger investigation of the coalbed methane resource potential of Pennsylvanian coals in north-central Texas. A total of 57 samples of coal and coaly shale fragments were hand-picked from drill cuttings from depths of about 2,000 ft in five wells, and Ro determinations were made on an initial 10-sample subset. Electric-log correlation of the sampled wells indicates that the collected samples represent coal and coaly shale layers in the Strawn (Pennsylvanian), Canyon (Pennsylvanian), and Cisco (Pennsylvanian-Permian) Groups. Coal rank in the initial sample subset ranges from lignite (Ro=0.39), in a sample from the Cisco Group at a depth of 310 to 320 ft, to high volatile bituminous A coal (Ro=0.91) in a sample from the lower part of the Canyon Group at a depth of 2,030 to 2,040 ft.

  16. Conference Summary

    Sanders, David B.

    2014-07-01

    This conference on ``Multi-wavelength AGN Surveys and Studies'' has provided a detailed look at the explosive growth over the past decade, of available astronomical data from a growing list of large scale sky surveys, from radio-to-gamma rays. We are entering an era were multi-epoch (months to weeks) surveys of the entire sky, and near-instantaneous follow-up observations of variable sources, are elevating time-domain astronomy to where it is becoming a major contributor to our understanding of Active Galactic Nuclei (AGN). While we can marvel at the range of extragalactic phenomena dispayed by sources discovered in the original ``Markarian Survey'' - the first large-scale objective prism survey of the Northern Sky carried out at the Byurakan Astronomical Observtory almost a half-century ago - it is clear from the talks and posters presented at this meeting that the data to be be obtained over the next decade will be needed if we are to finally understand which phase of galaxy evolution each Markarian Galaxy represents.

  17. The near ultraviolet spectra of comets P/Brorsen-Metcalf and Austin

    1990-01-01

    Results are reported on spectrophotometric observations of comets P/Brorsen-Metcalf and Austin from 3000 to 3600 A at a spectral resolution of about 1.8 A. The strongest features are the OH(A-X) 0-0 and 1-1 bands, and the NH(A-X) 0-0 bands. For the first time, the OH(A-X) 0-1 band was clearly found. The existence of the CN(B-X) 2-1 and 3-2 bands were verified and measured. A feature at 3258 A that was first seen in uncalibrated spectra was detected, and was identified as the NH singlet (c-a) 0-0 transition. The CO2(+) features at 3378, 3504, and 3512 A were also firmly identified. This ion was reported as being present in the tail of Comet Bester (1984 I) by Swings and Page (1950). The identification of a weak feature at 3547 A was proposed as the fundamental transition of H2CO, which would make this the first optical cometary detection of this molecule which is very abundant in giant molecular clouds.

  18. Edwin Austin Abbey's The Passage of the Hours: Astronomy as History

    NASA Astrophysics Data System (ADS)

    Ricci, P. L.

    2016-01-01

    The Passage of the Hours (1909-1911) in the Pennsylvania State Capitol at Harrisburg is one of the most original and least known astronomical ceilings in the United States. Designed by the American artist Edwin Austin Abbey (1852-1911) to complement the Italian Renaissance style architecture of the House of Representatives, the mural combines two classical traditions of representing the night sky: a celestial map with the constellations of the zodiac and the personifications of the Hours. Set in a shallow dome twenty-four feet in diameter, Abbey's constellation figures float in a dazzling firmament where the Milky Way streams between the Sun and the Moon. The artist placed the Horae of Greek mythology around the dome's circumference in the position of the numbers on an astronomical clock. In the tradition of Italian Renaissance architecture, the celestial ceiling in the House of Representatives was part of an iconographic program affirming the cosmological origin of a polity. The astronomical theme relates to Abbey's murals in the House Chamber of the first public reading of the Declaration of Independence in 1776 from David Rittenhouse's observatory in Philadelphia, which the astronomer constructed to study the transit of Venus in 1769. The artist included a portrait of Rittenhouse holding his telescope among the worthies in the adjacent mural of The Apotheosis of Pennsylvania. Contemporary as well as historical events encouraged Abbey's use of astronomical imagery: the depiction of a comet may record the much-anticipated return of Halley's Comet in 1910.

  19. Rearrangement of REE's in Austin Glen Fm. (Ord. ), Ulster Co. , NY

    1993-03-01

    Austin Glen turbidites are part of the allochthonous Taconic sequence of the Appalachian foreland basin. Graywackes in the sequence are rich in quartz, sedimentary rock fragments and carbonate, but have little feldspar. The abundant matrix makes it difficult to recognize volcanic components. REE patterns and Nd isotopes were analyzed to distinguish the relative abundance of volcanic versus older crustal components. REE patterns for shales and graywackes in a hundred-meter section are characterized by variable LREE-enrichment. An inclined array was expected on the f[sub Sm/Md] [minus] [var epsilon][sub Nd] diagram resulting from mixed sources. The vertical array shows that the samples had the same Nd-isotopic composition at 470 Ma. The restricted [var epsilon][sub Nd] of 8.0 [plus minus] 0.4 indicates the provenance was dominated by older crustal components that likely had similar Sm/Nd. The large variation in f[sub Sm/Nd] requires rearrangement of the REEs during sedimentary processes or early diagenesis at about 470 Ma.

  20. A radio source occultation experiment with comet Austin 1982g, with unusual results

    NASA Technical Reports Server (NTRS)

    De Pater, I.; Ip, W.-H.

    1984-01-01

    A radio source occultation by comet Austin 1982g was observed on September 15-16, 1982. A change in the apparent position of 1242 + 41 by 1.3 arcsec occurred when the source was 220,000 km away from the cometary ion tail. If this change was due to refraction by the cometary plasma, it indicates an electron density of the plasma of about 10,000/cu cm. When the radio source was on the other side of the plasma tail, at a distance of 230,000 km, the position angle of the electric vector of the radio source changed gradually over about 140 deg within two hours. This observation cannot be explained in terms of ionospheric Faraday rotation, and results from either an intrinsic change in the radio source or Faraday rotation in the cometary plasma due to a change in the direction and/or strength of the magnetic field. In the latter case, the cometary coma must have an electron density and a magnetic field strength orders of magnitude larger than current theories predict.
