The Institute for Geophysics in the Jackson School of Geosciences at The University of Texas at Austin actively contributes to K-12 education, including the development of rigorous Earth and Space Science curriculum designed for secondary school learning environments. Here we report on our efforts to apply an innovative new pedagogical approach, the Legacy Cycle, to scientific ocean drilling paleoclimate data from fossil corals collected offshore Barbados in 2006 and to the creation of a high school water resources education program for Texas high school students supported by a grant from the Texas Water Development Board. The Legacy Cycle makes use of the Internet and computer technology to engage students in extended inquiry learning. A series of inquiry activities are organized around a set of three driving questions, or challenges. Students mimic the work of scientists by generating ideas to address a given challenge, listening to multiple perspectives from experts on the topic, researching a set of sub-questions and revising their original ideas, testing their mettle with labs and quizzes, and finally composing a project or paper that answers the original challenge. The technology makes it easy for students to move through the challenges and the organizational framework since there are hyperlinks to each of the sections (and to reach the other challenges) at the bottom of each webpage. Students' final work is posted to the Internet for others to see, and in this way they leave behind their legacy. Our Legacy Cycle activities use authentic hydrologic, water quality, geochemical, geophysical data, as well as remotely sensed data such as is collected by satellites. They are aligned with the U.S. National Science Education Standards, the new Ocean, Climate and Earth Science Literacy Principles (in development), and the Texas Essential Knowledge and Skills for Earth and Space Science. The work represents a collaboration involving teachers from The University of Texas' UTeach program, the NSF-sponsored Texas Earth and Space Science (TXESS) Revolution program of teacher professional development, and the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching, and scientists from the Institute for Geophysics, the Lamont-Doherty Earth Observatory and the Texas Water Development Board.

Methodology for quantifying uncertainty in coal assessments with an application to a Texas lignite deposit

USGS Publications Warehouse

Olea, R.A.; Luppens, J.A.; Tewalt, S.J.

2011-01-01

A common practice for characterizing uncertainty in coal resource assessments has been the itemization of tonnage at the mining unit level and the classification of such units according to distance to drilling holes. Distance criteria, such as those used in U.S. Geological Survey Circular 891, are still widely used for public disclosure. A major deficiency of distance methods is that they do not provide a quantitative measure of uncertainty. Additionally, relying on distance between data points alone does not take into consideration other factors known to have an influence on uncertainty, such as spatial correlation, type of probability distribution followed by the data, geological discontinuities, and boundary of the deposit. Several geostatistical methods have been combined to formulate a quantitative characterization for appraising uncertainty. Drill hole datasets ranging from widespread exploration drilling to detailed development drilling from a lignite deposit in Texas were used to illustrate the modeling. The results show that distance to the nearest drill hole is almost completely unrelated to uncertainty, which confirms the inadequacy of characterizing uncertainty based solely on a simple classification of resources by distance classes. The more complex statistical methods used in this study quantify uncertainty and show good agreement between confidence intervals in the uncertainty predictions and data from additional drilling. ?? 2010.

Preliminary evaluation of the coal resources for part of the Wilcox Group (Paleocene through Eocene), central Texas

The Wilcox Group of central Texas contains shallow (<500 ft) coal deposits that are mined for use in mine-mouth electric power generating plants. These coal deposits range in apparent rank from lignite to sub-bituminous (Tewalt, 1986), and are similar in rank and composition to shallow coal deposits in the northeast and south Texas areas (fig. 1). The coal zones and associated strata in the central Texas study area generally dip to the southeast toward the Gulf of Mexico coastline and basin center. The central Texas resource assessment area includes parts of eight counties (fig. 2). The assessment area was selected to encompass current mining areas and because of the availability of subsurface stratigraphic data in the area. The assessment area is roughly 160 miles long and 5 to 25 miles wide and generally follows the outcrop of the Paleocene - Eocene Wilcox Group in central Texas (figs. 1 and 2). Approximately 1,800 subsurface stratigraphic records from rotary and core drill holes were used to assess the resources of the central Texas assessment area. Of the 1,800 drill holes, only 168 are public data points and are primarily located in the areas that have been permitted for surface mining (fig. 2; Appendix 1). The remaining 1632 drill holes, which are distributed throughout the assessment area, were provided to the U.S. Geological Survey (USGS) on a confidential basis by various coal companies for use in regional studies. Nine coal zones were identified and assessed in the central Texas assessment area. Several other coal zones (as many as 9 unassessed zones) were identified but were not assessed due to the thinness of the coal beds or the lack of deep stratigraphic data (fig. 3). A total of 7.7 billion short tons of coal was identified in this assessment that excluded the resources within current coal mine lease areas (fig. 2). Corresponding maps were constructed to show the overburden, structure contour of the top of the coal zone, and cumulative coal-zone thickness for each of the nine coal zones. Warwick and Crowley (1995) offer a discussion of the general geologic setting and stratigraphy of the central Texas study area, and Tewalt (1986) presents a discussion of the coal quality aspects of the central Texas study area.

2005-12-01

Many different types of data were collected during SAFOD Phases 1 and 2 (2004-2005) as part of the National Science Foundation's EarthScope program as well as from the SAFOD Pilot Hole, drilled in 2002 and funded by the International Continental Drilling Program (ICDP). Both SAFOD and the SAFOD Pilot Hole are being conducted as a close collaboration between NSF, the U.S. Geological Survey and the ICDP. SAFOD data products include cuttings, core and fluid samples; borehole geophysical measurements; and strain, tilt, and seismic recordings from the multilevel SAFOD borehole monitoring instruments. As with all elements of EarthScope, these data (and samples) are openly available to members of the scientific and educational communities. This paper presents the acquisition, storage and distribution plan for SAFOD data products. Washed and unwashed drill cuttings and mud samples were collected during Phases 1 and 2, along with three spot cores at depths of 1.5, 2.5, and 3.1 km. A total of 52 side-wall cores were also collected in the open-hole interval between 2.5 and 3.1 km depth. The primary coring effort will occur during Phase 3 (2007), when we will continuously core up to four, 250-m-long multilaterals directly within and adjacent to the San Andreas Fault Zone. Drill cuttings, core, and fluid samples from all three Phases of SAFOD drilling are being curated under carefully controlled conditions at the Integrated Ocean Drilling Program (IODP) Gulf Coast Repository in College Station, Texas. Photos of all physical samples and a downloadable sample request form are available on the ICDP website (http://www.icdp-online.de/sites/sanandreas/index/index.html). A suite of downhole geophysical measurements was conducted during the first two Phases of SAFOD drilling, as well as during drilling of the SAFOD Pilot Hole. These data include density, resistivity, porosity, seismic and borehole image logs and are also available via the ICDP website. The SAFOD monitoring program includes fiber-optic strain, tilt, seismic and fluid-pressure recording instruments. Seismic data from the Pilot Hole array are now available in SEED format from the Northern California Earthquake Data Center (http://quake.geo.berkeley.edu/safod/). The strain and tilt instruments are still undergoing testing and quality assurance, and these data will be available through the same web site as soon as possible. Lastly, two terabytes of unprocessed (SEG-2 format) data from a two-week deployment of an 80-level seismic array during April/May 2005 by Paulsson Geophysical Services, Inc. are now available via the IRIS data center (http://www.iris.edu/data/data.htm). Drilling parameters include real-time descriptions of drill cuttings mineralogy, drilling mud properties, and mechanical data related to the drilling process and are available via the ICDP web site. Current status reports on SAFOD drilling, borehole measurements, sampling, and monitoring instrumentation will continue to be available from the EarthScope web site (http://www.earthscope.org).

Field testing advanced geothermal turbodrill (AGT). Phase 1 final report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Maurer, W.C.; Cohen, J.H.

1999-06-01

Maurer Engineering developed special high-temperature geothermal turbodrills for LANL in the 1970s to overcome motor temperature limitations. These turbodrills were used to drill the directional portions of LANL`s Hot Dry Rock Geothermal Wells at Fenton Hill, New Mexico. The Hot Dry Rock concept is to drill parallel inclined wells (35-degree inclination), hydraulically fracture between these wells, and then circulate cold water down one well and through the fractures and produce hot water out of the second well. At the time LANL drilled the Fenton Hill wells, the LANL turbodrill was the only motor in the world that would drill atmore » the high temperatures encountered in these wells. It was difficult to operate the turbodrills continuously at low speed due to the low torque output of the LANL turbodrills. The turbodrills would stall frequently and could only be restarted by lifting the bit off bottom. This allowed the bit to rotate at very high speeds, and as a result, there was excessive wear in the bearings and on the gauge of insert roller bits due to these high rotary speeds. In 1998, Maurer Engineering developed an Advanced Geothermal Turbodrill (AGT) for the National Advanced Drilling and Excavation Technology (NADET) at MIT by adding a planetary speed reducer to the LANL turbodrill to increase its torque and reduce its rotary speed. Drilling tests were conducted with the AGT using 12 1/2-inch insert roller bits in Texas Pink Granite. The drilling tests were very successful, with the AGT drilling 94 ft/hr in Texas Pink Granite compared to 45 ft/hr with the LANL turbodrill and 42 ft/hr with a rotary drill. Field tests are currently being planned in Mexico and in geothermal wells in California to demonstrate the ability of the AGT to increase drilling rates and reduce drilling costs.« less

Guevara, Edgar H.; Breton, Caroline; Hackley, Paul C.

2007-01-01

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.

2003-12-01

The Integrated Ocean Drilling Program (IODP) began on October 1, 2003, following the end of operations of the 20-year Ocean Drilling Program (ODP). Education and outreach is a key component of IODP both nationally and internationally. The JOI Alliance (Joint Oceanographic Institutions, Inc., Texas A&M University, and Lamont Doherty Earth Observatory of Columbia University) will lead activities related to the U.S. drillship, coordinating these education and outreach efforts with those undertaken by the Central Management Organization, other IODP platform operators, and a U.S. Science Support Program successor. The Alliance will serve the national and assist the international scientific drilling communities by providing the results from the U.S. vessel to the public, government representatives, and scientists. The Alliance will expand upon media outreach strategies that were successful in ODP, such as issuing press releases at the conclusion of each leg and for major scientific breakthroughs; conducting tours, press conferences, and events during port calls; working with the press at major scientific meetings, and encouraging journalists to sail on expeditions. The Alliance will increase its education role by developing, coordinating, and disseminating educational materials and programs for teachers and students on the scientific themes and discoveries of IODP science. An important component of the outreach plan is using the vessel and associated laboratories and repositories as classrooms. IODP plans include multiple ship berths each year for teachers, based on the success of a pilot program conducted by ODP in 2001. This program, featuring a teacher onboard for a cruise, was accompanied by a distance-learning program and on-line curriculum models. Teachers can tour, both virtually and directly, laboratories and core repositories and participate in scheduled activities and courses. Using science conducted onboard the ship, the Alliance will develop online curriculum materials, as well as publications and fact sheets geared toward nonscientists. The Alliance will partner with existing scientific and education organizations, including programs at their universities, to widely disseminate IODP results and materials.

Union Texas Petroleum Holdings Inc. has resolved to transplant elsewhere in the world the success of tis 20 year old grass-roots exploration effort on the Badin block in Pakistan. Union Texas Pakistan Inc. (UTP) is actively seeking exploration concessions in Pakistan, and the parent company is on an international bent aimed at finding other areas where it might reproduce its performance in Pakistan. The 104 exploratory wells drilled through April 1, 1997, resulted in 47 discoveries and 57 dry holes for a 45% success rate. Some oil and gas are produced from the Middle Sand units, and some gas ismore » produced from the Basal Sand units. The 1997 Badin exploration plan called for 11 exploratory wells, including one, Tarai Deep-3, that would test a new play concept in Jurassic Chiltan. It also called for Badin`s first 3D seismic surveys, at South Buzdar and Tangri fields on the northern part of the block, and 146 km of 2D seismic acquisition. The paper discusses Badin development, drilling status, operating challenges, oil price and sales, gas markets, local effects, and future developments.« less

We monitored the bacterial communities in the gas-water separator and water storage tank of two newly drilled natural gas wells in the Barnett Shale in north central Texas, using a 16S rRNA gene pyrosequencing approach over a period of 6 months. Overall, the communities were composed mainly of moderately halophilic and halotolerant members of the phyla Firmicutes and Proteobacteria (classes Βeta-, Gamma-, and Epsilonproteobacteria) in both wells at all sampling times and locations. Many of the observed lineages were encountered in prior investigations of microbial communities from various fossil fluid formations and production facilities. In all of the samples, multiple H(2)S-producing lineages were encountered; belonging to the sulfate- and sulfur-reducing class Deltaproteobacteria, order Clostridiales, and phylum Synergistetes, as well as the thiosulfate-reducing order Halanaerobiales. The bacterial communities from the separator and tank samples bore little resemblance to the bacterial communities in the drilling mud and hydraulic-fracture waters that were used to drill these wells, suggesting the in situ development of the unique bacterial communities in such well components was in response to the prevalent geochemical conditions present. Conversely, comparison of the bacterial communities on temporal and spatial scales suggested the establishment of a core microbial community in each sampled location. The results provide the first overview of bacterial dynamics and colonization patterns in newly drilled, thermogenic natural gas wells and highlights patterns of spatial and temporal variability observed in bacterial communities in natural gas production facilities.

International Collaboration in Data Management for Scientific Ocean Drilling: Preserving Legacy Data While Implementing New Requirements.

NASA Astrophysics Data System (ADS)

Rack, F. R.

2005-12-01

The Integrated Ocean Drilling Program (IODP: 2003-2013 initial phase) is the successor to the Deep Sea Drilling Project (DSDP: 1968-1983) and the Ocean Drilling Program (ODP: 1985-2003). These earlier scientific drilling programs amassed collections of sediment and rock cores (over 300 kilometers stored in four repositories) and data organized in distributed databases and in print or electronic publications. International members of the IODP have established, through memoranda, the right to have access to: (1) all data, samples, scientific and technical results, all engineering plans, data or other information produced under contract to the program; and, (2) all data from geophysical and other site surveys performed in support of the program which are used for drilling planning. The challenge that faces the individual platform operators and management of IODP is to find the right balance and appropriate synergies among the needs, expectations and requirements of stakeholders. The evolving model for IODP database services consists of the management and integration of data collected onboard the various IODP platforms (including downhole logging and syn-cruise site survey information), legacy data from DSDP and ODP, data derived from post-cruise research and publications, and other IODP-relevant information types, to form a common, program-wide IODP information system (e.g., IODP Portal) which will be accessible to both researchers and the public. The JANUS relational database of ODP was introduced in 1997 and the bulk of ODP shipboard data has been migrated into this system, which is comprised of a relational data model consisting of over 450 tables. The JANUS database includes paleontological, lithostratigraphic, chemical, physical, sedimentological, and geophysical data from a global distribution of sites. For ODP Legs 100 through 210, and including IODP Expeditions 301 through 308, JANUS has been used to store data from 233,835 meters of core recovered, which are comprised of 38,039 cores, with 202,281 core sections stored in repositories, which have resulted in the taking of 2,299,180 samples for scientists and other users (http://iodp.tamu.edu/janusweb/general/dbtable.cgi). JANUS and other IODP databases are viewed as components of an evolving distributed network of databases, supported by metadata catalogs and middleware with XML workflows, that are intended to provide access to DSDP/ODP/IODP cores and sample-based data as well as other distributed geoscience data collections (e.g., CHRONOS, PetDB, SedDB). These data resources can be explored through the use of emerging data visualization environments, such as GeoWall, CoreWall (http://(www.evl.uic.edu/cavern/corewall), a multi-screen display for viewing cores and related data, GeoWall-2 and LambdaVision, a very-high resolution, networked environment for data exploration and visualization, and others. The U.S Implementing Organization (USIO) for the IODP, also known as the JOI Alliance, is a partnership between Joint Oceanographic Institutions (JOI), Texas A&M University, and Lamont-Doherty Earth Observatory of Columbia University. JOI is a consortium of 20 premier oceanographic research institutions that serves the U.S. scientific community by leading large-scale, global research programs in scientific ocean drilling and ocean observing.

McFarland, M.L.; Hartmann, S.; Ueckert, D.N.

Surface disposal of spent drilling fluids used in petroleum and natural gas exploration causes surface soil contamination that severely inhibits secondary plant succession and artificial revegetation efforts. Selective-placement burial was evaluated at two locations in western Texas for on-site disposal of drilling fluids in arid and semiarid regions. Establishment, yield, and chemical composition of fourwing saltbrush (Atriplex canescens (Pursh Nutt.)) and buffalograss (Buchloe dactyloides (Nutt.) Engelm.) transplants on undisturbed soils and on plots with spent drilling fluids and cuttings buried 30, 90 (with and without a 30-cm coarse limestone capillary barrier) and 150 cm were compared. Survival of both speciesmore » was 97 to 100% 17 months after planting on plots with buried drilling wastes. Canopy cover and aboveground biomass of fourwing saltbrush were greater over buried drilling wastes than on untreated plots, whereas canopy cover and aboveground biomass of buffalograss were not affected by the treatments. Significant increases in Na, M, and Mg concentrations in buffalograss after 17 months on plots with drilling fluids buried 30 cm deep at one location indicated plant uptake of some drilling fluid constituents. Elevated Zn concentrations in fourwing saltbush indicated that a portion of the Zn in the drilling fluids was available for plant uptake, while no evidence of plant accumulation of Ba, Cr, Cu, or Ni from drilling fluids was detected.« less

Potential for deep basin-centered gas accumulation in Travis Peak (Hosston) Formation, Gulf Coastal Basin

Bartberger, Charles E.; Dyman, Thaddeus S.; Condon, Steven M.

2003-01-01

The potential of Lower Cretaceous sandstones of the Travis Peak Formation in the northern Gulf Coast Basin to harbor a basin-centered gas accumulation was evaluated by examining (1) the depositional and diagenetic history and reservoir properties of Travis Peak sandstones, (2) the presence and quality of source rocks for generating gas, (3) the burial and thermal history of source rocks and time of gas generation and migration relative to tectonic development of Travis Peak traps, (4) gas and water recoveries from drill-stem and formation tests, (5) the distribution of abnormal pressures based on shut-in-pressure data, and (6) the presence or absence of gas-water contacts associated with gas accumulations in Travis Peak sandstones. The Travis Peak Formation (and correlative Hosston Formation) is a basinward-thickening wedge of terrigenous clastic sedimentary rocks that underlies the northern Gulf Coast Basin from eastern Texas across northern Louisiana to southern Mississippi. Clastic infl ux was focused in two main fl uvial-deltaic depocenters?one located in northeastern Texas and the other in southeastern Mississippi and northeastern Louisiana. Across the main hydrocarbon-productive trend in eastern Texas and northern Louisiana, the Travis Peak Formation is about 2,000 ft thick. Most Travis Peak hydrocarbon production in eastern Texas comes from drilling depths between 6,000 and 10,000 ft. Signifi cant decrease in porosity and permeability occurs through that depth interval. Above 8,000-ft drilling depth in eastern Texas, Travis Peak sandstone matrix permeabilities often are signifi cantly higher than the 0.1-millidarcy (mD) cutoff that characterizes tight-gas reservoirs. Below 8,000 ft, matrix permeability of Travis Peak sandstones is low because of pervasive quartz cementation, but abundant natural fractures impart signifi cant fracture permeability. Although pressure data within the middle and lower Travis Peak Formation are limited in eastern Texas, overpressured reservoirs caused by thermal generation of gas, typical of basin-centered gas accumulations, are not common in the Travis Peak Formation. Signifi cant overpressure was found in only one Travis Peak sandstone reservoir in 1 of 24 oil and gas fi elds examined across eastern Texas and northern Louisiana. The presence of gas-water contacts is perhaps the most defi nitive criterion indicating that a gas accumulation is conventional rather than a ?sweet spot? within a basin-centered gas accumulation. Hydrocarbon-water contacts within Travis Peak sandstone reservoirs were documented in 17 fi elds and probably occur in considerably more fi elds across the productive Travis Peak trend in eastern Texas and northern Louisiana. All known hydrocarbon-water contacts in Travis Peak reservoirs in eastern Texas, however, occur within sandstones in the upper 500 ft of the formation. Although no gas-water contacts have been reported within the lower three-fourths of the Travis Peak Formation in northeastern Texas, gas production from that interval is limited. The best available data suggest that most middle and lower Travis Peak sandstones are water bearing in northeastern Texas. Insuffi cient hydrocarbon charge relative to permeability of Travis Peak reservoirs might be responsible for lack of overpressure and basin-centered gas within the Travis Peak Formation. Shales interbedded with Travis Peak sandstones in eastern Texas are primarily oxidized fl ood-plain deposits with insuffi cient organic-carbon content to be signifi cant sources of oil and gas. The most likely source rocks for hydrocarbons in Travis Peak reservoirs are two stratigraphically lower units, the Jurassic-age Bossier Shale of the Cotton Valley Group, and laminated, lime mudstones of the Jurassic Smackover Formation. Hydrocarbon charge, therefore, might be suffi cient for development of conventional gas accumulations, but it is insuffi cient for

Influence of the Drilling Mud Formulation Process on the Bacterial Communities in Thermogenic Natural Gas Wells of the Barnett Shale▿†

2011-01-01

The Barnett Shale in north central Texas contains natural gas generated by high temperatures (120 to 150°C) during the Mississippian Period (300 to 350 million years ago). In spite of the thermogenic origin of this gas, biogenic sulfide production and microbiologically induced corrosion have been observed at several natural gas wells in this formation. It was hypothesized that microorganisms in drilling muds were responsible for these deleterious effects. Here we collected drilling water and drilling mud samples from seven wells in the Barnett Shale during the drilling process. Using quantitative real-time PCR and microbial enumerations, we show that the addition of mud components to drilling water increased total bacterial numbers, as well as the numbers of culturable aerobic heterotrophs, acid producers, and sulfate reducers. The addition of sterile drilling muds to microcosms that contained drilling water stimulated sulfide production. Pyrosequencing-based phylogenetic surveys of the microbial communities in drilling waters and drilling muds showed a marked transition from typical freshwater communities to less diverse communities dominated by Firmicutes and Gammaproteobacteria. The community shifts observed reflected changes in temperature, pH, oxygen availability, and concentrations of sulfate, sulfonate, and carbon additives associated with the mud formulation process. Finally, several of the phylotypes observed in drilling muds belonged to lineages that were thought to be indigenous to marine and terrestrial fossil fuel formations. Our results suggest a possible alternative exogenous origin of such phylotypes via enrichment and introduction to oil and natural gas reservoirs during the drilling process. PMID:21602366

This multimedia report shows and describes digital three-dimensional faulted geologic surfaces and volumes of the lithologic units of the Edwards aquifer in the upper Seco Creek area of Medina and Uvalde Counties in south-central Texas. This geologic framework model was produced using (1) geologic maps and interpretations of depositional environments and paleogeography; (2) lithologic descriptions, interpretations, and geophysical logs from 31 drill holes; (3) rock core and detailed lithologic descriptions from one drill hole; (4) helicopter electromagnetic geophysical data; and (5) known major and minor faults in the study area. These faults were used because of their individual and collective effects on the continuity of the aquifer-forming units in the Edwards Group. Data and information were compared and validated with each other and reflect the complex relationships of structures in the Seco Creek area of the Balcones fault zone. This geologic framework model can be used as a tool to visually explore and study geologic structures within the Seco Creek area of the Balcones fault zone and to show the connectivity of hydrologic units of high and low permeability between and across faults. The software can be used to display other data and information, such as drill-hole data, on this geologic framework model in three-dimensional space.

Understanding Science and Technology Interactions Through Ocean Science Exploration: A Summer Course for Science Teachers

2003-12-01

In order to replenish the national supply of science and mathematics educators, the National Science Foundation has supported the formation of the Center for Applications of Information Technology in the Teaching and Learning of Science (ITS) at Texas A&M University. The center staff and affiliated faculty work to change in fundamental ways the culture and relationships among scientists, educational researchers, and teachers. ITS is a partnership among the colleges of education, science, geosciences, agriculture and life science at Texas A&M University. Participants (teachers and graduate students) investigate how science is done and how science is taught and learned; how that learning is assessed, and how scholarly networks among all engaged in this work can be encouraged. While the center can offer graduate degrees most students apply as non-degree seekers. ITS participants are schooled on classroom technology applications, experience working on project teams, and access very current research work being conducted by scientists. ITS offers a certificate program consisting of two summer sessions over two years that results in 12 hours of graduate credit that can be applied to a degree. Interdisciplinary project teams spend three intense weeks connecting current research to classroom practices. During the past summer with the beginning of the two-year sequence, a course was implemented that introduced secondary teachers to Ocean Drilling Program (ODP) contributions to major earth science themes, using core and logging data, engineering (technology) tools and processes. Information Technology classroom applications were enhanced through hands-on laboratory exercises, web resources and online databases. The course was structured around the following objectives. 1. Distinguish the purpose and goals of the Ocean Drilling Program from the Integrated Ocean Drilling Program and describe the comparable science themes (ocean circulation, marine sedimentation, climate history, sea level change and geological time). This objective will be achieved by correctly answering 8 of 10 multiple choice items on course posttest on science themes of ODP/IODP. 2. Describe the technical tools and processes for determining sea level history by preparing and presenting a multimedia presentation on coring. 3. Describe the processes for describing a drill core and apply those processes to core samples from Leg 194 by developing a laboratory analysis report on core samples based on protocol for analyzing cores. 4. Explain the distinguishing features of scientific from industrial coring processes by developing a paper that contrasts scientific from industrial coring processes. 5. Describe the substructure of the ocean basin and the scientific tools (equipment and processes) used to explore this substructure by preparing and presenting a multimedia presentation on bore hole data interpretation. 6. Analyze and interpret data sets from a bore hole by developing a laboratory analysis report on bore-hole data. Student performance data for objectives indicate a 16% average positive change on the science themes addressed in instruction related to objective one occurred. Similarly, a 12% average positive change occurred on science education topics related to earth science among the students in this class. Ongoing contact between faculty members during the academic year is planned as these summer participants engage in implementing IT interventions and professional development experiences based on ocean science data experienced in the summer experience.

Water Use by Texas Oil and Gas Industry: A Look towards the Future

2009-12-01

The Barnett Shale gas play, located in North Texas, has seen a relatively quick growth in the past decade with the development of new “frac” (aka, fracture stimulation) technologies needed to create pathways to produce gas from the very low permeability shales. This technology uses a large amount of fresh water (millions of gallons in a day or two on average) to develop a gas well. Now operators are taking aim at other shale gas plays in Texas including the Haynesville, Woodford, and Pearsall-Eagle Ford shales and at other tight formation such as the Bossier Sand. These promising gas plays are likely to be developed at an even steeper growth rate. There are currently over 12,000 wells producing gas from the Barnett Shale with many more likely to be drilled in the next couple of decades as the play expands out of its core area. Despite the recent gas price slump, thousands more wells may be drilled across the state to access the gas resource in the next few years. As an example, a typical vertical and horizontal well completion in the Barnett Shale consumes approximately 1.2 and 3.0 to 3.5 millions gallons of fresh water, respectively. This could raise some concerns among local communities and other surface water and groundwater stakeholders. We present a preliminary analysis of future water use by the Texas oil and gas industry and compare it to projections of total water use, including municipal use and irrigation. Maps showing large increase in total number of well completions in the Barnett Shale (black dots) from 1998 to 2008. Operators avoided the DFW metro area (center right on the map) until recently. Also shown are the structural limits of the Barnett Shale on its eastern boundaries.

2015-12-01

The booming unconventional oil and gas industry in the Eagle Ford shale in southern Texas continues to grow. Modeling studies of the air quality impacts of the Eagle Ford rely on emission inventories that may underestimate emissions from such operations, and air quality monitoring in the area remains limited. We conducted an air quality study on a ranch in Dimmit County, Texas, which was ranked 6th in Texas for natural gas production and 10th in Texas for oil production as of April 2015. An automated GC-FID was used to measure the concentration of hydrocarbons (C3 - C14), with concurrent measurements of CO, CO2, H2O, O3, NO/NOx. In addition, the concentration and sizing of aerosols ranging from 0.6 to 20 µm aerodynamic diameter were measured with a GRIMM aerosol spectrometer (GRIMM 1.108), and meteorological variables including wind speed, direction, temperature, relative humidity, precipitation, and insolation were recorded. We report on local air quality and changes during the process as observed during the measurement campaign. Local drilling on the ranch began in May 2015 and production started in June 2015, at a site approximately 5 km southeast of the air quality trailer. Local air quality showed typically low, near background abundances of CO and NOx early during the campaign, and more frequent local NOx plumes during the drilling and production phases. Aerosol mass measurements were also relatively low and well within attainment of NAAQS particulate matter standards. We assess OH radical reactivity of individual and/or groups of VOCs using observed concentrations and their reaction rate coefficient with OH, the dominant VOC sink in the troposphere.

The Corpus Christi, Texas, based Cameron Equipment Co., Inc., has developed a closed-loop mud treating system that removes solids from water-based systems and leaves the separated fluid clean and chemical free enough to be re-used directly on the rig. The system has been successfully applied by a Gulf of Mexico operator in areas where zero discharge is required. The alternative mud conditions program offered by the developers is called the Cameron Fluid Recycling System. Designed for closed-loop water-based fluids, the system is a new method of removing solids from normally discharged fluids such as drilling mud, waste and wash water,more » or any other water-based fluid that contains undesirable solids. The patented method efficiently produces end products that are (1) dry solids; and (2) essentially 100% solids-free fluid that can be re-used in the same mud system. All excess drilling mud, and all wash water that would normally go to the reserve pit or a cuttings barge are collected in a tank. Recycled fluid is compatible with the mud system fluid, no harmful chemicals are used, and pH is not altered.« less

National and regional trends in water-well drilling in the United States, 1964-84

Information on national and regional water-well drilling activity is important for water-resource planning and management and for water-related equipment marketing. This report describes a study to analyze drilling trends on the basis of data for selected years from 1964 through 1984. The study focused primarily on the years 1964 and 1980-84 but also included data from 1960. Approximately 397,000 water wells were drilled in the United States in 1984. Seven States, Florida, Texas, New York, Michigan, North Carolina, Virginia, and Ohio, accounted for 39 percent of all the wells drilled in the United States in 1984. Florida led the Nation in drilling activity with 45,600 new wells. The 1984 national drilling total was 2.6 percent greater than the total for 1980 (387,000) and 8.5 percent less than the total for 1964 (434,000). However, these moderate differences do not reflect substantial year-to-year fluctuations that may have occurred during that 20-year period. Qualitative comparisons suggest that drilling activity for a given year is closely related to the number of housing starts for that year. If so, there may have been peaks in drilling activity in 1972 and 1977-78 (corresponding to peaks in housing starts) that are not identified in this study because of a lack of available well-drilling data for those years. Well-drilling data for 1964 and the 1980-84 period probably represent a low to moderate level of drilling activity and, if compared to earlier data, suggest that there has been no substantial growth or decline in the water-well industry as a whole since the 1940's.

Horizontal exploitation of the Upper Cretaceous Austin Chalk of south Texas

DOE Office of Scientific and Technical Information (OSTI.GOV)

Borkowski, R.; Hand, L.; Dickerson, D.

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 suchmore » 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.« less

Chip samples from rotary drilling in the vicinity of a roll-type uranium deposit in the southwestern San Juan Basin were split into a whole-washed fraction, a clay fraction, and a heavy mineral concentrate fraction. Analyses of these fractions determined that cutting samples could be used to identify geochemical halos associated with this ore deposit. In addition to showing a distribution of selenium, uranium, vanadium, and molybdenum similar to that described by Harshman (1974) in uranium roll-type deposits in Wyoming, South Dakota, and Texas, the chemical data indicate a previously unrecognized zinc anomaly in the clay fraction downdip of the uranium ore.

A deep drilling research program titled 'An Industry/DOE Program to Develop and Benchmark Advanced Diamond Product Drill Bits and HP/HT Drilling Fluids to Significantly Improve Rates of Penetration' was conducted at TerraTek's Drilling and Completions Laboratory. Drilling tests were run to simulate deep drilling by using high bore pressures and high confining and overburden stresses. The purpose of this testing was to gain insight into practices that would improve rates of penetration and mechanical specific energy while drilling under high pressure conditions. Thirty-seven test series were run utilizing a variety of drilling parameters which allowed analysis of the performance ofmore » drill bits and drilling fluids. Five different drill bit types or styles were tested: four-bladed polycrystalline diamond compact (PDC), 7-bladed PDC in regular and long profile, roller-cone, and impregnated. There were three different rock types used to simulate deep formations: Mancos shale, Carthage marble, and Crab Orchard sandstone. The testing also analyzed various drilling fluids and the extent to which they improved drilling. The PDC drill bits provided the best performance overall. The impregnated and tungsten carbide insert roller-cone drill bits performed poorly under the conditions chosen. The cesium formate drilling fluid outperformed all other drilling muds when drilling in the Carthage marble and Mancos shale with PDC drill bits. The oil base drilling fluid with manganese tetroxide weighting material provided the best performance when drilling the Crab Orchard sandstone.« less

Efficiency in energy production and consumption

NASA Astrophysics Data System (ADS)

Kellogg, Ryan Mayer

This dissertation deals with economic efficiency in the energy industry and consists of three parts. The first examines how joint experience between pairs of firms working together in oil and gas drilling improves productivity. Part two asks whether oil producers time their drilling optimally by taking real options effects into consideration. Finally, I investigate the efficiency with which energy is consumed, asking whether extending Daylight Saving Time (DST) reduces electricity use. The chapter "Learning by Drilling: Inter-Firm Learning and Relationship Persistence in the Texas Oilpatch" examines how oil production companies and the drilling rigs they hire improve drilling productivity by learning through joint experience. I find that the joint productivity of a lead firm and its drilling contractor is enhanced significantly as they accumulate experience working together. Moreover, this result is robust to other relationship specificities and standard firm-specific learning-by-doing effects. The second chapter, "Drill Now or Drill Later: The Effect of Expected Volatility on Investment," investigates the extent to which firms' drilling behavior accords with a key prescription of real options theory: irreversible investments such as drilling should be deferred when the expected volatility of the investments' payoffs increases. I combine detailed data on oil drilling with expectations of future oil price volatility that I derive from the NYMEX futures options market. Conditioning on expected price levels, I find that oil production companies significantly reduce the number of wells they drill when expected price volatility is high. I conclude with "Daylight Time and Energy: Evidence from an Australian Experiment," co-authored with Hendrik Wolff. This chapter assesses DST's impact on electricity demand using a quasi-experiment in which parts of Australia extended DST in 2000 to facilitate the Sydney Olympics. We show that the extension did not reduce overall electricity consumption, but did cause a substantial intra-day shift in demand consistent with activity patterns that are tied to the clock rather than sunrise and sunset.

The discovery and character of Pleistocene calcrete uranium deposits in the Southern High Plains of west Texas, United States

USGS Publications Warehouse

Van Gosen, Bradley S.; Hall, Susan M.

2017-12-18

This report describes the discovery and geology of two near-surface uranium deposits within calcareous lacustrine strata of Pleistocene age in west Texas, United States. Calcrete uranium deposits have not been previously reported in the United States. The west Texas uranium deposits share characteristics with some calcrete uranium deposits in Western Australia—uranium-vanadium minerals hosted by nonpedogenic calcretes deposited in saline lacustrine environments.In the mid-1970s, Kerr-McGee Corporation conducted a regional uranium exploration program in the Southern High Plains province of the United States, which led to the discovery of two shallow uranium deposits (that were not publicly reported). With extensive drilling, Kerr-McGee delineated one deposit of about 2.1 million metric tons of ore with an average grade of 0.037 percent U3O8 and another deposit of about 0.93 million metric tons of ore averaging 0.047 percent U3O8.The west-Texas calcrete uranium-vanadium deposits occur in calcareous, fine-grained sediments interpreted to be deposited in saline lakes formed during dry interglacial periods of the Pleistocene. The lakes were associated with drainages upstream of a large Pleistocene lake. Age determinations of tephra in strata adjacent to one deposit indicate the host strata is middle Pleistocene in age.Examination of the uranium-vanadium mineralization by scanning-electron microscopy indicated at least two generations of uranium-vanadium deposition in the lacustrine strata identified as carnotite and a strontium-uranium-vanadium mineral. Preliminary uranium-series results indicate a two-component system in the host calcrete, with early lacustrine carbonate that was deposited (or recrystallized) about 190 kilo-annum, followed much later by carnotite-rich crusts and strontium-uranium-vanadium mineralization in the Holocene (about 5 kilo-annum). Differences in initial 234U/238U activity ratios indicate two separate, distinct fluid sources.

Analysis of borehole geophysical information across a uranium deposit in the Jackson Group, Karnes County, Texas

USGS Publications Warehouse

Daniels, Jeffrey J.; Scott, James Henry; Smith, Bruce D.

1979-01-01

Borehole geophysical studies across a uranium deposit in the Jackson Group, South Texas, show the three geochemical environments often associated with uranium roll-type deposits: an altered (oxidized) zone, an ore zone, and an unaltered (reduced) zone. Mineralogic analysis of the total sulfides contained in the drill core shows only slight changes in the total sulfide content among the three geochemical regimes. However, induced polarization measurements on the core samples indicate that samples obtained from the reduced side of the ore zone are more electrically polarizable than those from the oxidized side of the ore zone, and therefore probably contain more pyrite. Analysis of the clay-size fraction in core samples indicates that montmorillonite is the dominant clay mineral. High resistivity values within the ore zone indicate the presence of calcite cement concentrations that are higher than those seen outside of the ore zone. Between-hole resistivity and induced polarization measurements show the presence of an extensive zone of calcite cement within the ore zone, and electrical polarizable material (such as pyrite) within and on the reduced side of the ore zone. A quantitative analysis of the between-hole resistivity data, using a layered-earth model, and a qualitative analysis of the between-hole induced polarization measurements showed that mineralogic variations among the three geochemical environments were more pronounced than were indicated by the geophysical and geologic well logs. Uranium exploration in the South Texas Coastal Plain area has focused chiefly in three geologic units: the Oakville Sandstone, the Catahoula Tuff, and the Jackson Group. The Oakville Sandstone and the Catahoula Tuff are of Miocene age, and the Jackson Group is of Eocene age (Eargle and others, 1971). Most of the uranium mineralization in these formations is low grade (often less than 0.02 percent U3O8) and occurs in shallow deposits that are found by concentrated exploratory drilling programs. The sporadic occurrence of these deposits makes it desirable to develop borehole geophysical techniques that will help to define the depositional environments of the uranium ore, which is characterized by geochemical changes near the uranium deposits. Geochemical changes are accompanied by changes in the physical characteristics of the rocks that can be detected with borehole geophysical tools. This study is concerned with a uranium deposit within the Jackson Group that is located just east of Karnes City, Tex. Five holes were drilled on this property to obtain borehole geophysical data and cores. The cores were analyzed for mineralogic and electrical properties. The borehole geophysical information at this property included induced polarization, resistivity, gamma-gamma density, neutron-neutron, gamma-ray, caliper, and single-point-resistance logs. Between-hole resistivity and induced polarization measurements were made between hole pairs across the ore deposit and off the ore deposit.

Results from Testing of Two Rotary Percussive Drilling Systems

NASA Technical Reports Server (NTRS)

Kriechbaum, Kristopher; Brown, Kyle; Cady, Ian; von der Heydt, Max; Klein, Kerry; Kulczycki, Eric; Okon, Avi

2010-01-01

The developmental test program for the MSL (Mars Science Laboratory) rotary percussive drill examined the e ect of various drill input parameters on the drill pene- tration rate. Some of the input parameters tested were drill angle with respect to gravity and percussive impact energy. The suite of rocks tested ranged from a high strength basalt to soft Kaolinite clay. We developed a hole start routine to reduce high sideloads from bit walk. The ongoing development test program for the IMSAH (Integrated Mars Sample Acquisition and Handling) rotary percussive corer uses many of the same rocks as the MSL suite. An additional performance parameter is core integrity. The MSL development test drill and the IMSAH test drill use similar hardware to provide rotation and percussion. However, the MSL test drill uses external stabilizers, while the IMSAH test drill does not have external stabilization. In addition the IMSAH drill is a core drill, while the MSL drill uses a solid powdering bit. Results from the testing of these two related drilling systems is examined.

Horizontal drilling in the Austin Chalk: Stratigraphic factors

DOE Office of Scientific and Technical Information (OSTI.GOV)

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. Horizontalmore » 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.« less

HIGH-POWER TURBODRILL AND DRILL BIT FOR DRILLING WITH COILED TUBING

DOE Office of Scientific and Technical Information (OSTI.GOV)

Robert Radtke; David Glowka; Man Mohan Rai

2008-03-31

Commercial introduction of Microhole Technology to the gas and oil drilling industry requires an effective downhole drive mechanism which operates efficiently at relatively high RPM and low bit weight for delivering efficient power to the special high RPM drill bit for ensuring both high penetration rate and long bit life. This project entails developing and testing a more efficient 2-7/8 in. diameter Turbodrill and a novel 4-1/8 in. diameter drill bit for drilling with coiled tubing. The high-power Turbodrill were developed to deliver efficient power, and the more durable drill bit employed high-temperature cutters that can more effectively drill hardmore » and abrasive rock. This project teams Schlumberger Smith Neyrfor and Smith Bits, and NASA AMES Research Center with Technology International, Inc (TII), to deliver a downhole, hydraulically-driven power unit, matched with a custom drill bit designed to drill 4-1/8 in. boreholes with a purpose-built coiled tubing rig. The U.S. Department of Energy National Energy Technology Laboratory has funded Technology International Inc. Houston, Texas to develop a higher power Turbodrill and drill bit for use in drilling with a coiled tubing unit. This project entails developing and testing an effective downhole drive mechanism and a novel drill bit for drilling 'microholes' with coiled tubing. The new higher power Turbodrill is shorter, delivers power more efficiently, operates at relatively high revolutions per minute, and requires low weight on bit. The more durable thermally stable diamond drill bit employs high-temperature TSP (thermally stable) diamond cutters that can more effectively drill hard and abrasive rock. Expectations are that widespread adoption of microhole technology could spawn a wave of 'infill development' drilling of wells spaced between existing wells, which could tap potentially billions of barrels of bypassed oil at shallow depths in mature producing areas. At the same time, microhole coiled tube drilling offers the opportunity to dramatically cut producers' exploration risk to a level comparable to that of drilling development wells. Together, such efforts hold great promise for economically recovering a sizeable portion of the estimated remaining shallow (less than 5,000 feet subsurface) oil resource in the United States. The DOE estimates this U.S. targeted shallow resource at 218 billion barrels. Furthermore, the smaller 'footprint' of the lightweight rigs utilized for microhole drilling and the accompanying reduced drilling waste disposal volumes offer the bonus of added environmental benefits. DOE analysis shows that microhole technology has the potential to cut exploratory drilling costs by at least a third and to slash development drilling costs in half.« less

The effects of school physical education grants on obesity, fitness, and academic achievement.

PubMed

von Hippel, Paul T; Bradbury, W Kyle

2015-09-01

Foundations and governments fund a number of programs that provide grants to improve school physical education or other forms of school-based physical activity. The effects of these grant programs are unknown. We evaluate the effects of Texas Fitness Now, a program in which the state of Texas granted $37 million to improve physical education in high-poverty middle schools over the 4 school years from 2007-08 to 2010-11. The stated goals of Texas Fitness Now were to reduce obesity, increase fitness, and raise academic achievement. We summarize how Texas Fitness Now funds were spent and estimate the impact of Texas Fitness Now using a fixed-effects longitudinal model that exploits changes in schools' eligibility over time. Changes in eligibility occurred when eligibility expanded to new schools after year 2 and when the program was terminated after year 4. Most Texas Fitness Now funds were spent on sports and fitness equipment. Smaller amounts were spent on anti-obesity curricula. Texas Fitness Now improved strength and flexibility, especially among girls, but it did not improve BMI or academic achievement, and it had mixed effects on aerobic capacity. The fitness benefits were not lost in the year after the program ended, perhaps because schools kept the equipment that they had bought during their years of eligibility. The results of Texas Fitness Now were typical for an intervention that relied almost exclusively on physical activity. Programs that improve BMI as well as fitness tend to have a more fully developed nutrition component. Copyright © 2015 Elsevier Inc. All rights reserved.

Overcoming Murphy`s Law to gain ERP - a case study at Gibbons Creek Lignite Mine, Texas

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lancaster, E.M.; Horbaczewski, J.K.

1997-12-31

As of January 1997, there are 2,586 acres of reclaimed land in the Extended Responsibility Period (ERP) at Gibbons Creek Lignite Mine, Texas. This achievement has taken approximately five years to accomplish - from 1991 to 1996. During this period, there were a number of issues, some of which appeared to follow Murphy`s Law (whatever can go wrong, will go wrong!). For example, the ERP candidate areas were split among three permit areas, which first had to be consolidated to facilitate the ERP process. Minesoil issues, identified as ERP prerequisites, became entangled in an overall renewal/revision of the newly-consolidated Permitmore » 26B. Special-purpose vegetation studies were performed to investigate the effects of different minesoil textures. In the meantime, small depressional areas, wetland/wildlife enhancement areas, reclamation ponds and restored drainages became the subjects of attention from landowners and regulatory agencies. Some of these structures and features were subsequently reclaimed; others were approved via the permitting process. In some cases, the only way out of the impasse was through land acquisition. Finally, after all these issues had been resolved, an unforeseen oil-well drilling program crisscrossed the proposed ERP areas with a network of oil well pads and service roads, requiring a post-mining land use change. Eventually, whatever could go wrong, went right, and entry of lands into ERP was accomplished.« less

Feltis, R.D.; Robinson, G.B. Jr.

1963-01-01

A test-drilling program was conducted by the U.S. Geological Survey in the upper Sevier River drainage basin (fig. 1) in the summer of 1962. The program was part of a ground-water investigation made in cooperation with the Utah State Engineer. The drilling was financed cooperatively through the State Engineer by the U.S. Geological Survey, Garfield, Piute, Sevier, Sanpete, and Millard Counties, and various water users within those counties. Drilling began in May and continued through September 1962, and 21 test holes were drilled.

Trends in hydraulic fracturing distributions and treatment fluids, additives, proppants, and water volumes applied to wells drilled in the United States from 1947 through 2010: data analysis and comparison to the literature

USGS Publications Warehouse

Gallegos, Tanya J.; Varela, Brian A.

2015-01-01

Hydraulic fracturing is presently the primary stimulation technique for oil and gas production in low-permeability, unconventional reservoirs. Comprehensive, published, and publicly available information regarding the extent, location, and character of hydraulic fracturing in the United States is scarce. This national spatial and temporal analysis of data on nearly 1 million hydraulically fractured wells and 1.8 million fracturing treatment records from 1947 through 2010 (aggregated in Data Series 868) is used to identify hydraulic fracturing trends in drilling methods and use of proppants, treatment fluids, additives, and water in the United States. These trends are compared to the literature in an effort to establish a common understanding of the differences in drilling methods, treatment fluids, and chemical additives and of how the newer technology has affected the water use volumes and areal distribution of hydraulic fracturing. Historically, Texas has had the highest number of records of hydraulic fracturing treatments and associated wells in the United States documented in the datasets described herein. Water-intensive horizontal/directional drilling has also increased from 6 percent of new hydraulically fractured wells drilled in the United States in 2000 to 42 percent of new wells drilled in 2010. Increases in horizontal drilling also coincided with the emergence of water-based “slick water” fracturing fluids. As such, the most current hydraulic fracturing materials and methods are notably different from those used in previous decades and have contributed to the development of previously inaccessible unconventional oil and gas production target areas, namely in shale and tight-sand reservoirs. Publicly available derivative datasets and locations developed from these analyses are described.

An interactive drilling simulator for teaching and research

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cooper, G.A.; Cooper, A.G.; Bihn, G.

1995-12-31

An interactive program has been constructed that allows a student or engineer to simulate the drilling of an oil well, and to optimize the drilling process by comparing different drilling plans. The program operates in a very user-friendly way, with emphasis on menu and button-driven commands. The simulator may be run either as a training program, with exercises that illustrate various features of the drilling process, as a game, in which a student is set a challenge to drill a well with minimum cost or time under constraints set by an instructor, or as a simulator of a real situationmore » to investigate the merit of different drilling strategies. It has three main parts, a Lithology Editor, a Settings Editor and the simulation program itself. The Lithology Editor allows the student, instructor or engineer to build a real or imaginary sequence of rock layers, each characterized by its mineralogy, drilling and log responses. The Settings Editor allows the definition of all the operational parameters, ranging from the drilling and wear rates of particular bits in specified rocks to the costs of different procedures. The simulator itself contains an algorithm that determines rate of penetration and rate of wear of the bit as drilling continues. It also determines whether the well kicks or fractures, and assigns various other {open_quotes}accident{close_quotes} conditions. During operation, a depth vs. time curve is displayed, together with a {open_quotes}mud log{close_quotes} showing the rock layers penetrated. If desired, the well may be {open_quotes}logged{close_quotes} casings may be set and pore and fracture pressure gradients may be displayed.

Modeling the mesozoic-cenozoic structural evolution of east texas

Pearson, Ofori N.; Rowan, Elisabeth L.; Miller, John J.

2012-01-01

The U.S. Geological Survey (USGS) recently assessed the undiscovered technically recoverable oil and gas resources within Jurassic and Cretaceous strata of the onshore coastal plain and State waters of the U.S. Gulf Coast. Regional 2D seismic lines for key parts of the Gulf Coast basin were interpreted in order to examine the evolution of structural traps and the burial history of petroleum source rocks. Interpretation and structural modeling of seismic lines from eastern Texas provide insights into the structural evolution of this part of the Gulf of Mexico basin. Since completing the assessment, the USGS has acquired additional regional seismic lines in east Texas; interpretation of these new lines, which extend from the Texas-Oklahoma state line to the Gulf Coast shoreline, show how some of the region's prominent structural elements (e.g., the Talco and Mount Enterprise fault zones, the East Texas salt basin, and the Houston diapir province) vary along strike. The interpretations also indicate that unexplored structures may lie beneath the current drilling floor. Structural restorations based upon interpretation of these lines illustrate the evolution of key structures and show the genetic relation between structural growth and movement of the Jurassic Louann Salt. 1D thermal models that integrate kinetics and burial histories were also created for the region's two primary petroleum source rocks, the Oxfordian Smackover Formation and the Cenomanian-Turonian Eagle Ford Shale. Integrating results from the thermal models with the structural restorations provides insights into the distribution and timing of petroleum expulsion from the Smackover Formation and Eagle Ford Shale in eastern Texas.

2013-03-01

Shell's "difficulties" during its 2012 program to drill offshore oil and natural gas exploration wells in the Alaskan Arctic Ocean "have raised serious questions regarding its ability to operate safely and responsibly in the challenging and unpredictable conditions offshore Alaska," according to the report "Review of Shell's 2012 Alaska Offshore Oil and Gas Exploration Program," issued by the U.S. Department of the Interior (DOI) on 8 March. Noting the company's lack of adequate preparation for drilling in the Arctic, its failure to deploy a specialized Arctic Containment System, and the grounding of the Kulluk drilling rig near Kodiak Island last December, the report recommends that Shell develop a comprehensive and integrated plan describing its future drilling program and related operations and that it commission a third-party audit of its management systems, including its safety and environmental management systems program.

2009-12-01

The TeXas Earth and Space Science (TXESS) Revolution, a professional development program for 8th- thru 12th-grade Earth Science teachers, presented a one-week Petroleum Science and Technology Institute at The University of Texas at Austin campus. The summer program was a joint effort between the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering. The goal of the institute was to focus on the STEM components involved in the petroleum industry and to introduce teachers to the larger energy resources theme. The institute kicked off with a welcoming event and tour of a green, energy-efficient home (LEED Platinum certified) owned by one of the petroleum engineering faculty. Tours of the home included an introduction to rainwater harvesting, solar energy, sustainable building materials and other topics on energy efficiency. Classroom topics included drilling technology (including a simulator lab and an overview of the history of the technology), energy use and petroleum geology, well-logging technology and interpretation, reservoir engineering and volumetrics (including numerous labs combining chemistry and physics), risk assessment and economics, carbon capture and storage (CO2 sequestration technology) and hydraulic fracturing. A mid-week field trip included visiting the Ocean Star offshore platform in Galveston, the Weiss Energy Hall at the Houston Museum of Science and Schlumberger (to view 3-D visualization technology) in Houston. Teachers remarked that they really appreciated the focused nature of the institute and especially found the increased use of mathematics both a tool for professional growth, as well as a challenge for them to use more math in their science classes. STEM integration was an important feature of the summer institute, and teachers found the integration of science (earth sciences, geophysics), technology, engineering (petroleum, chemical and reservoir) and mathematics particularly valuable. Pre-conception surveys and post-tests indicate a significant gain in these teachers' knowledge of petroleum science and technology. In particular, teachers noted that a large area of new knowledge was gained in the area of carbon capture and storage technology.

Uniform Distribution of Yttrium and Heavy Rare Earth Elements in Round Top Mountain Rhyolite Deposit , Sierra Blanca Texas, USA: Data, Significance, and Origin

NASA Astrophysics Data System (ADS)

Pingitore, N. E., Jr.; Clague, J. W.; Gorski, D.

2014-12-01

The Round Top Mountain peraluminous rhyolite, exposed at the surface in Sierra Blanca, Hudspeth County, west Texas, USA, is enriched in yttrium and heavy rare earth elements (YHREEs). Other potentially valuable elements in the deposit include Be, Li, U, Th, Sn, F, Nb, and Ta. Texas Rare Earth Resources Corp. proposes to extract the YHREEs from the host mineral variety yttrofluorite by inexpensive heap leaching with dilute sulfuric acid, which also releases some of the Be, Li, U, F, and Th from other soluble minor minerals. Data: Feldspars and quartz comprise 90-95% of the rhyolite, with pheonocrysts of up to 250 microns set in an aphanitic matrix that hosts the typically sub-micron target yttrofluorite. Reverse circulation cuttings from some 100 drill holes, two drill cores, and outcrop and trench observations suggest striking physical homogeneity through this billion-plus ton surface-exposed laccolith, about 1200 feet high and a mile in diameter (375 x 1600 m). Gray to pink, and other minor hues, color variation derives from magnetite—hematite redox reaction. Plots of Y, 13 REEs, U, Th, and Nb analyses from over 1500 samples collected from 64 drill holes (color codes in figure) exhibit remarkably little variation in the concentration of these elements with geographic position or depth within the laccolith. Importance: Uniform mineralization grades help insure against the mining production surprises often associated with vein deposits and heterogeneous open pit deposits. At Round Top, mine feedstock can be relatively constant over the life of the mine (multiple decades), so the mechanical mining process can be optimized early on and not need expensive alterations later. Likewise, the chemical and physical parameters of the heap leach can be perfected. The sensitive and expensive process of extraction of elements and element groups from the pregnant leach solution and purification also can be optimized. Origin: The remarkable homogeneity of the YHREE distribution through the laccolith suggest YHREE and associated mineralization from a late-stage fluorine vapor generated within the magma in situ, rather than from injection of a F-rich fluid from an external source. The micron-scale cavities that produce up to 5% original porosity in the rhyolite may be nano-analogues of the cavities associated with granite pegmatites.

Reservoir characterization using core, well log, and seismic data and intelligent software

NASA Astrophysics Data System (ADS)

Soto Becerra, Rodolfo

We have developed intelligent software, Oilfield Intelligence (OI), as an engineering tool to improve the characterization of oil and gas reservoirs. OI integrates neural networks and multivariate statistical analysis. It is composed of five main subsystems: data input, preprocessing, architecture design, graphics design, and inference engine modules. More than 1,200 lines of programming code as M-files using the language MATLAB been written. The degree of success of many oil and gas drilling, completion, and production activities depends upon the accuracy of the models used in a reservoir description. Neural networks have been applied for identification of nonlinear systems in almost all scientific fields of humankind. Solving reservoir characterization problems is no exception. Neural networks have a number of attractive features that can help to extract and recognize underlying patterns, structures, and relationships among data. However, before developing a neural network model, we must solve the problem of dimensionality such as determining dominant and irrelevant variables. We can apply principal components and factor analysis to reduce the dimensionality and help the neural networks formulate more realistic models. We validated OI by obtaining confident models in three different oil field problems: (1) A neural network in-situ stress model using lithology and gamma ray logs for the Travis Peak formation of east Texas, (2) A neural network permeability model using porosity and gamma ray and a neural network pseudo-gamma ray log model using 3D seismic attributes for the reservoir VLE 196 Lamar field located in Block V of south-central Lake Maracaibo (Venezuela), and (3) Neural network primary ultimate oil recovery (PRUR), initial waterflooding ultimate oil recovery (IWUR), and infill drilling ultimate oil recovery (IDUR) models using reservoir parameters for San Andres and Clearfork carbonate formations in west Texas. In all cases, we compared the results from the neural network models with the results from regression statistical and non-parametric approach models. The results show that it is possible to obtain the highest cross-correlation coefficient between predicted and actual target variables, and the lowest average absolute errors using the integrated techniques of multivariate statistical analysis and neural networks in our intelligent software.

Geology of the Southern Guadalupe Mountains, Texas

USGS Publications Warehouse

King, Philip B.

1948-01-01

This report deals with an area of 425 square miles in the western part of Texas, immediately south of the New Mexico line. The area comprises the south end of the Guadalupe Mountains and the adjacent part of the Delaware Mountains; it includes the highest peaks in the State of Texas. The area is a segment of a large mountain mass that extends 50 miles or more northward and southward. The report describes the geology of the area, that is, the nature of its rocks, tectonics, and surface features, and the evidence that they give as to the evolution of the area through geologic time. Incidental reference is made to the geology of surrounding regions in order to place the area in its environment. The Permian system of the southwestern United States has been until recently one of the intriguing but little known subjects of American stratigraphy. In the latter half of the nineteenth century after the western. United States was settled, the "red bed" sections of the Permian were studied and reported on by many geologists, but up to 1920 the existence of a contemporaneous marine sequence in western Texas and southeastern New Mexico was little appreciated. Since that year the discovery of extensive oil fields and potash beds in this region gave an impetus to the study of the Permian rocks, and furnished the geologist with records of hundreds of drill holes from which to deduce the nature of the strata not exposed at the surface. At the same time geologists have studied the rocks in the outcropping areas, and have compared them with the strata encountered by drilling.Much remains to be done in order to understand the history of Permian time in the region. The physical and chemical conditions that caused. the deposition of .the various and often complexly related deposits need to be better understood. More of the fossils of the rich and interesting marine faunas should be described, and the relations of the fossils to their environments should be determined. Further, a satisfactory scheme of correlation is needed, and also a subdivision into series that will express the contemporaneity of strata in different areas. One useful contribution to the solution of these problems is the detailed study of sequences of rocks exposed at the surface in the different mountain ranges of Texas and New Mexico.This report deals with one such sequence of rocks in western Texas, the one exposed in the southern Guadalupe Mountains (fig. 1). Here, the Permian rocks are magnificently exposed, to a thickness of about 4,000 feet (pl. 1). They are all of marine origin, and belong to the middle part of the system, with the base concealed and the top absent. Overlying and underlying beds, however, are found in nearby areas.

Salton Sea Scientific Drilling Program

USGS Publications Warehouse

Sass, J.H.

1988-01-01

The Salton Sea Scientific Drilling Program (SSSDP) was the first large-scale drilling project undertaken by the U.S Continental Scientific Drilling Program. The objectives of the SSSDP were (1) to drill a deep well into the Salton Sea Geothermal Field in the Imperial Valley of California, (2) to retrieve a high percentage of core and cuttings along the entire depth of the well, (3) to obtain a comprehensive suite of geophysical logs, (4) to conduct flow tests at two depths  (and to take fluid samples therefrom), and (5) to carry out several downhole experiments. These activites enabled the U.S Geological Survey and cooperating agencies to study the physical and chemical processes involved in an active hydrothermal system driven by a molten-rock heat source. This program, orginally conceived by Wilfred A. Elders, professor of geology at the University of California at Riverside, was coordinated under an inter-agency accord among the Geological Survey, the U.S Department of Energy, and the National Science Foundation.

The Affordance Template ROS Package for Robot Task Programming

NASA Technical Reports Server (NTRS)

Hart, Stephen; Dinh, Paul; Hambuchen, Kimberly

2015-01-01

This paper introduces the Affordance Template ROS package for quickly programming, adjusting, and executing robot applications in the ROS RViz environment. This package extends the capabilities of RViz interactive markers by allowing an operator to specify multiple end-effector waypoint locations and grasp poses in object-centric coordinate frames and to adjust these waypoints in order to meet the run-time demands of the task (specifically, object scale and location). The Affordance Template package stores task specifications in a robot-agnostic XML description format such that it is trivial to apply a template to a new robot. As such, the Affordance Template package provides a robot-generic ROS tool appropriate for building semi-autonomous, manipulation-based applications. Affordance Templates were developed by the NASA-JSC DARPA Robotics Challenge (DRC) team and have since successfully been deployed on multiple platforms including the NASA Valkyrie and Robonaut 2 humanoids, the University of Texas Dreamer robot and the Willow Garage PR2. In this paper, the specification and implementation of the affordance template package is introduced and demonstrated through examples for wheel (valve) turning, pick-and-place, and drill grasping, evincing its utility and flexibility for a wide variety of robot applications.

Optimizing Geothermal Drilling: Oil and Gas Technology Transfer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tilley, Mitch; Eustes, Alfred; Visser, Charles

There is a significant amount of financial risk associated with geothermal drilling; however, there are opportunities to improve upon current practices and technologies used. The scope of this drilling operational study included 21 geothermal wells and 21 oil and gas wells. The goal was to determine a 'perfect well' using historical data to compare the best oil and gas well to the best geothermal well. Unfortunately, limitations encountered in the study included missing data (bit records, mud information, etc.), poor data collection, and difficult to ascertain handwriting. An online software database was used to format drilling data to IADC codedmore » daily drilling reports and generate analysis figures. Six major issues have been found in geothermal drilling operations. These problems include lost circulation, rig/equipment selection, cementing, penetration rate, drilling program, and time management. As a result of these issues, geothermal drilling averages 56.4 days longer than drilling comparable oil and gas wells in the wells in this study. Roughly $13.9 million would be lost due to non-productive time in the 21 geothermal wells and only $1.3 million in the oil and gas wells, assuming a cost of $50,000 per day. Comparable events such as drilling the same sized hole, tripping in/out, cementing, and running the same size casing took substantially less time in the oil and gas wells. Geothermal wells were drilled using older and/or less advanced technology to depths less than 10,000 feet, while oil and gas wells reached 12,500 feet faster with purpose built rigs. A new approach is now underway that will optimize drilling programs throughout the drilling industry. It is the use of Mechanical Specific Energy (MSE) as a tool to realize efficient drilling processes. However, a work-flow must also be established in order for there to be an efficient drilling program. Potential improvements for current geothermal operations are: the use of electronic records, real time services, and official glossary terms to describe rig operations, and advanced drilling rigs/technology.« less

EPA proposes to find that these changes to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations and are consistent with EPA policies. Texas submitted revisions to these programs on June 10, 2005, and February 1, 2006. EPA disapproved these SIP revisions on September 15, 2010 (75 FR 56424). In response to the 2010 disapproval, Texas submitted revisions to these programs in two separate SIP submittals on March 11, 2011. These SIP submittals include resubmittal of the rules that were previously submitted June 10, 2005, and February 1, 2006, and subsequently disapproved by EPA on September 15, 2010. On February 22, 2012, Texas proposed further revisions to the NSR Reform Program to further clarify and ensure compliance with Federal requirements relating to NSR Reform. On May 3, 2012, Texas provided a letter to EPA which requested that EPA parallel process the revisions proposed February 22, 2012, and included a demonstration showing how its submitted rules are at least as stringent as the Federal NSR Reform Program. Texas has requested that EPA parallel process the revisions proposed February 22, 2012, and consider the May 3, 2012, letter in the review of the March 11, 2011, SIP submittals.

Teaching Marine Geoscience at Sea: Integrated Ocean Drilling Program's School of Rock Explores Cascadia Subduction Zone - Cores, Logs, and ACORKs

NASA Astrophysics Data System (ADS)

Reagan, M.; Collins, J.; Ludwig, K. A.; Slough, S.; Delaney, M. L.; Hovan, S. A.; Expedition 328 Scientists

2010-12-01

For twelve days this past September, seventeen formal and informal educators from the US, UK, and France joined six instructors and a small science party on the scientific drillship JOIDES Resolution for the Integrated Ocean Drilling Program (IODP)’s Cascadia ACORK Expedition. The educators were part of the annual “School of Rock (SOR)” education program. SOR is coordinated by the U.S. Implementing Organization (USIO) of IODP and is designed to engage participants in seagoing Earth systems research and education workshops onboard the JOIDES Resolution and on shore at the Gulf Coast Core Repository in Texas. The scientific objective of the Cascadia ACORK expedition was to install a new permanent hydrologic observatory at ODP Site 889 to provide long-term monitoring of the pressure at the frontal part of the Cascadia accretionary prism. This year’s SOR workshop focused on how cores, logs, and ACORKs shed light on the hydrology and geology of the Cascadia subduction zone in the Northeast Pacific. In addition to observing the deployment of the ACORK, the SOR participants conducted daily hands-on analyses of archived sediment and hard-rock cores with scientists and technicians who specialize in IODP research using the lab facilities on the ship. Throughout the expedition, participants engaged in different activities and lessons designed to explore the deep biosphere, methane hydrates, paleoceanography, sedimentology, biostratigraphy, seafloor spreading, and drilling technology. The workshop also provided participants with “C3” time; time to communicate their experience using the successful joidesresolution.org website and other tools, make connections to their prior knowledge and expertise, and to be creative in developing and planning new education and outreach activities based on their new knowledge and research. As part of participating in the expedition, participants committed to further developing and testing their education and outreach products after the expedition, conducting post-expedition projects in conjunction with the U.S. Implementing Organization and their own institutions, and to participating actively in post-cruise evaluation. Since its inception in 2005, 75 SOR graduates and staff have conducted over 150 workshops and short courses for 3,000 participants in more than 30 U.S. states and five other nations. Integral to the success of the program is the evaluation process that takes place during and after each SOR. In particular, SOR evaluations take advantage of the power of video data collection to demonstrate the transformative nature of SOR expeditions. Video evaluations offer a unique opportunity to collect and preserve participant “voice” to document true transformative broader impacts. Along with video evaluations, the program also employs more traditional evaluation methods such as internal evaluator observations, open-ended questionnaires, and participant journals.

The Geological Sciences department at the University of Texas at El Paso (UTEP) hosted the EarthTech outreach program - a one-week intensive summer camp for low-income, at-risk high school students. The EarthTech program engaged students in STEM activities from geological and environmental sciences. Developed and led by university student-mentors with guidance from a supervising faculty member, the course engaged Upward Bound students with lectures, interactive projects, and excursions to local ecological preserves and geological sites around El Paso, Texas. Topics covered plant and animal distribution and diversity, water and soil dynamics, evolution and paleontology, geohazards, and planetary science. Field trips were combined with hands-on activities, including activities from DIG Texas teaching modules. The NSF-funded DIG Texas Instructional Blueprints project is organizing vetted, high quality online educational resources and learning activities into teaching modules. The modules follow a storyline and demonstrate congruency with the Next Generation Science Standards. Selected DIG Texas resources were included in the daily curriculum to complement the field trip and other hands-on activities. EarthTech students created ESRI Online GIS story maps in which they showed the locations of the field trips, incorporated photographs they had taken, and provided written reflections about their camp experiences. The DIG Texas project evaluation collected survey and interview data from the university student mentors throughout the week to ascertain the efficacy of the program. This poster presentation will include an overview of the program, including examples of work and evaluation results.

Flared natural gas-based onsite atmospheric water harvesting (AWH) for oilfield operations

NASA Astrophysics Data System (ADS)

Wikramanayake, Enakshi D.; Bahadur, Vaibhav

2016-03-01

Natural gas worth tens of billions of dollars is flared annually, which leads to resource waste and environmental issues. This work introduces and analyzes a novel concept for flared gas utilization, wherein the gas that would have been flared is instead used to condense atmospheric moisture. Natural gas, which is currently being flared, can alternatively power refrigeration systems to generate the cooling capacity for large scale atmospheric water harvesting (AWH). This approach solves two pressing issues faced by the oil-gas industry, namely gas flaring, and sourcing water for oilfield operations like hydraulic fracturing, drilling and water flooding. Multiple technical pathways to harvest atmospheric moisture by using the energy of natural gas are analyzed. A modeling framework is developed to quantify the dependence of water harvest rates on flared gas volumes and ambient weather. Flaring patterns in the Eagle Ford Shale in Texas and the Bakken Shale in North Dakota are analyzed to quantify the benefits of AWH. Overall, the gas currently flared annually in Texas and North Dakota can harvest enough water to meet 11% and 65% of the water consumption in the Eagle Ford and the Bakken, respectively. Daily harvests of upto 30 000 and 18 000 gallons water can be achieved using the gas currently flared per well in Texas and North Dakota, respectively. In fifty Bakken sites, the water required for fracturing or drilling a new well can be met via onsite flared gas-based AWH in only 3 weeks, and 3 days, respectively. The benefits of this concept are quantified for the Eagle Ford and Bakken Shales. Assessments of the global potential of this concept are presented using data from countries with high flaring activity. It is seen that this waste-to-value conversion concept offers significant economic benefits while addressing critical environmental issues pertaining to oil-gas production.

Application of an Area-of-Review (AOR) Concept to the East Texas Field and Other Selected Texas Oilfields

DOE Office of Scientific and Technical Information (OSTI.GOV)

Warner, Don L.; Koederitz, Leonard F.; Laudon, Robert C.

The Underground Injection Control Regulations promulgated in 1980, under the Safe Drinking Water Act of 1974, require Area-of-Review (AOR) studies be conducted as part of the permitting process for newly drilled or converted Class II injection wells. Existing Class II injection wells operating at the time regulations became effective were excluded from the AOR requirement. The AOR is the area surrounding an injection well or wells defined by either the radial distance within which pressure in the injection zone may cause migration of the injection and/or formation fluid into an underground source of drinking water (USDW) or defined by amore » fixed radius of not less than one-fourth mile. In the method where injection pressure is used to define the AOR radial distance, the AOR is also known as the ''zone of endangering influence.''« less

Abeyta, Cynthia G.; Frenzel, P.F.

1999-01-01

Geologic and hydrologic data for the Municipal Solid Waste Landfill Facility on the U.S. Army Air Defense Artillery Center and Fort Bliss in El Paso County, Texas, were collected by the U.S. Geological Survey in cooperation with the U.S. Department of the Army. The 106.03-acre landfill has been in operation since January 1974. The landfill contains household refuse, Post solid wastes, bulky items, grass and tree trimmings from family housing, refuse from litter cans, construction debris, classified waste (dry), dead animals, asbestos, and empty oil cans. The depth of the filled areas is about 30 feet and the cover, consisting of locally derived material, is 2 to 3 feet thick. Geologic and hydrologic data were collected at or adjacent to the landfill during (1) drilling of 10 30- to 31-foot boreholes that were completed with gas-monitoring probes, (2) drilling of a 59-foot borehole, (3) drilling of a 355-foot borehole that was completed as a ground-water monitoring well, and (4) in situ measurements made on the landfill cover. After completion, the gas- monitoring probes were monitored on a quarterly basis (1 year total) for gases generated by the landfill. Water samples were collected from the ground-water monitoring well for chemical analysis. Data collection is divided into two elements: geologic data and hydrologic data. Geologic data include lithologic descriptions of cores and cuttings, geophysical logs, soil- gas and ambient-air analyses, and chemical analyses of soil. Hydrologic data include physical properties, total organic carbon, and pH of soil and sediment samples; soil-water chloride and soil-moisture analyses; physical properties of the landfill cover; measurements of depth to ground water; and ground-water chemical analyses. Interpretation of data is not included in this report.

The Cattle Fever Tick Eradication Program was the first parasite eradication program of veterinary importance in the United States and is considered to be one of the greatest disease eradication programs of all time. The program's utilization of pasture vacation and dipping of cattle in acaricide has been extremely successful for controlling Rhipicephalus (Boophilus) microplus (Canestrini) and R. (B.) annulatus (Say), collectively known as cattle fever ticks, on cattle along the Texas border with Mexico for decades. However, the increase of white-tailed deer, Odocoileus virginianus (Zimmermann), populations in South Texas over the last 50 yr has compromised the success of the program. R. (B.) microplus and R. (B.) annulatus infestation data have confirmed that O. virginianus can support the maintenance and movement of both species of cattle fever tick within the permanent quarantine or buffer zone in South Texas along the Rio Grande, and also in the cattle fever tick-free area north and east of the buffer zone. Over the last two decades, increasing populations of exotic nilgai antelope, Boselaphus tragocamelus (Pallas), in South Texas have further complicated cattle fever tick eradication efforts. Historical cattle fever tick infestation data, host source data, and geographical data support the continued role of O. virginianus in maintaining reinfestations of R. (B.) microplus and R. (B.) annulatus in South Texas as well as the increasing role of nilgai antelope in cattle fever tick maintenance and dispersal.

Rock melting technology and geothermal drilling

NASA Technical Reports Server (NTRS)

Rowley, J. C.

1974-01-01

National awareness of the potential future shortages in energy resources has heightened interest in exploration and utilization of a variety of geothermal energy (GTE) reservoirs. The status of conventional drilling of GTE wells is reviewed briefly and problem areas which lead to higher drilling costs are identified and R and D directions toward solution are suggested. In the immediate future, an expanded program of drilling in GTE formations can benefit from improvements in drilling equipment and technology normally associated with oil or gas wells. Over a longer time period, the new rock-melting drill bits being developed as a part of the Los Alamos Scientific Laboratory's Subterrene Program offer new solutions to a number of problems which frequently hamper GTE drilling, including the most basic problem - high temperature. Two of the most favorable characteristics of rock-melting penetrators are their ability to operate effectively in hot rock and produce glass linings around the hole as an integral part of the drilling process. The technical advantages to be gained by use of rock-melting penetrators are discussed in relation to the basic needs for GTE wells.

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

DOE Office of Scientific and Technical Information (OSTI.GOV)

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 zonesmore » 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.« less

Description and results of test-drilling program at Picatinny Arsenal, New Jersey, 1982-84

USGS Publications Warehouse

Harte, P.T.; Sargent, B.P.; Vowinkel, E.F.

1986-01-01

Picatinny Arsenal, located in north-central New Jersey, has a long history of explosives manufacturing. Past industrial activities and past waste-disposal practices have caused some groundwater contamination problems. In 1982, the U.S. Geological Survey, in cooperation with the U.S. Army, began a water resources investigation of the Arsenal. The test drilling program is designed to define the hydrogeology and install observation wells. Twenty-two boreholes were drilled and 21 observation wells installed in these holes. All drilling was done in a glaciated valley. The report includes lithologic and gamma-ray logs, results of grain-size analyses, well-construction data, and some groundwater levels. The generalized stratigraphic sequence of geologic units penetrated from the test-drilling program are from lower to upper: (1) pre-dominantly dolomitic Leithsville Formation, (2) in the upper part of bedrock, a weathered dolomite zone, (3) a thin discontinuous mantle of till, and (4) stratified drift deposit up to 208 ft thick.

CENSUS AND STATISTICAL CHARACTERIZATION OF SOIL AND WATER QUALITY AT ABANDONED AND OTHER CENTRALIZED AND COMMERCIAL DRILLING-FLUID DISPOSAL SITES IN LOUISIANA, NEW MEXICO, OKLAHOMA, AND TEXAS

DOE Office of Scientific and Technical Information (OSTI.GOV)

Alan R. Dutton; H. Seay Nance

2003-06-01

Commercial and centralized drilling-fluid disposal (CCDD) sites receive a portion of spent drilling fluids for disposal from oil and gas exploration and production (E&P) operations. Many older and some abandoned sites may have operated under less stringent regulations than are currently enforced. This study provides a census, compilation, and summary of information on active, inactive, and abandoned CCDD sites in Louisiana, New Mexico, Oklahoma, and Texas, intended as a basis for supporting State-funded assessment and remediation of abandoned sites. Closure of abandoned CCDD sites is within the jurisdiction of State regulatory agencies. Sources of data used in this study onmore » abandoned CCDD sites mainly are permit files at State regulatory agencies. Active and inactive sites were included because data on abandoned sites are sparse. Onsite reserve pits at individual wells for disposal of spent drilling fluid are not part of this study. Of 287 CCDD sites in the four States for which we compiled data, 34 had been abandoned whereas 54 were active and 199 were inactive as of January 2002. Most were disposal-pit facilities; five percent were land treatment facilities. A typical disposal-pit facility has fewer than 3 disposal pits or cells, which have a median size of approximately 2 acres each. Data from well-documented sites may be used to predict some conditions at abandoned sites; older abandoned sites might have outlier concentrations for some metal and organic constituents. Groundwater at a significant number of sites had an average chloride concentration that exceeded nonactionable secondary drinking water standard of 250 mg/L, or a total dissolved solids content of >10,000 mg/L, the limiting definition for underground sources of drinking water source, or both. Background data were lacking, however, so we did not determine whether these concentrations in groundwater reflected site operations. Site remediation has not been found necessary to date for most abandoned CCDD sites; site assessments and remedial feasibility studies are ongoing in each State. Remediation alternatives addressed physical hazards and potential for groundwater transport of dissolved salt and petroleum hydrocarbons that might be leached from wastes. Remediation options included excavation of wastes and contaminated adjacent soils followed by removal to permitted disposal facilities or land farming if sufficient on-site area were available.« less

Integrating petroleum and sulfur data to map the Guadalupian-Ochoan (Middle to Upper Permian) Boundary of the Delaware Basis, Trans-Pecos, Texas

NASA Astrophysics Data System (ADS)

Dishron, Joseph B.

2011-12-01

The Delaware Basin of the Permian Basin is a classic intra-cratonic basin of West Texas and Southeast New Mexico. Hydrocarbon exploration and production have occurred in the region since the early 1920s, and, as a result, the formations related to these oil and gas reserves have been studied in great detail. Some formations in the Delaware Basin, however, have not been studied in such detail, and this thesis examines one, lesser-known unit that could have economic potential. The Lamar Limestone (Lamar Lime) of the Bell Canyon Formation has commonly been dismissed as a production interval; rather, it has been described as a source and seal rock for the Ramsey Sand of the lower Bell Canyon Formation. However, recent studies found that the Lamar Lime was contributing to production, and it has been described by Trentham (2006) as a potentia "mini Barnett" reservoir. The depths of these deposits are in a range that is ideal for oil accumulation. This study made use of data from wells and test holes drilled in the western Delaware Basin, Culberson County, Texas. Many oil and gas wells have been drilled in the western Delaware Basin, but they are concentrated in the north and east portions of Culberson County. In addition, sulfur wells were drilled in the area in the late 1960s and early 1970s. Analyses of the well logs of these wells and of core and outcrop studies were completed to gain a better understanding of the distribution and economic potential of the Lamar. Both datasets were combined to provide information not readily available in the oil and gas dataset. The Lamar Lime is an excellent marker bed because it underlies thick evaporites. The evaporite sequences are Ochoan in age, and, therefore, the contact of the Lamar Lime (Bell Canyon Formation) and the Castile Formation is the approximate boundary for the Guadalupian-Ochoan Series. The Castile Formation, the Salado Formation, and the Rustler Formation (from oldest to youngest) are the evaporite units that consist of halite, gypsum, and anhydrite and are discussed herein. The boundary also marks a significant faunal-extinction event. The high organic content found in the Lamar Lime helps to evaluate the economic potential. Updated isopach and structural contour maps extend the knowledge of the Lamar Lime more to the western Delaware Basin.

Gas Hydrate Research Site Selection and Operational Research Plans

NASA Astrophysics Data System (ADS)

Collett, T. S.; Boswell, R. M.

2009-12-01

In recent years it has become generally accepted that gas hydrates represent a potential important future energy resource, a significant drilling and production hazard, a potential contributor to global climate change, and a controlling factor in seafloor stability and landslides. Research drilling and coring programs carried out by the Ocean Drilling Program (ODP), the Integrated Ocean Drilling Program (IODP), government agencies, and several consortia have contributed greatly to our understanding of the geologic controls on the occurrence of gas hydrates in marine and permafrost environments. For the most part, each of these field projects were built on the lessons learned from the projects that have gone before them. One of the most important factors contributing to the success of some of the more notable gas hydrate field projects has been the close alignment of project goals with the processes used to select the drill sites and to develop the project’s operational research plans. For example, IODP Expedition 311 used a transect approach to successfully constrain the overall occurrence of gas hydrate within the range of geologic environments within a marine accretionary complex. Earlier gas hydrate research drilling, including IODP Leg 164, were designed primarily to assess the occurrence and nature of marine gas hydrate systems, and relied largely on the presence of anomalous seismic features, including bottom-simulating reflectors and “blanking zones”. While these projects were extremely successful, expeditions today are being increasingly mounted with the primary goal of prospecting for potential gas hydrate production targets, and site selection processes designed to specifically seek out anomalously high-concentrations of gas hydrate are needed. This approach was best demonstrated in a recently completed energy resource focused project, the Gulf of Mexico Gas Hydrate Joint Industry Project Leg II (GOM JIP Leg II), which featured the collection of a comprehensive set of logging-while-drilling (LWD) data through expected gas-hydrate-bearing sand reservoirs in seven wells at three sites in the Gulf of Mexico. The discovery of thick hydrate-bearing sands at two of the sites drilled in the Gulf Mexico validated the integrated geological and geophysical approach used in the pre-drill site selection process to identify gas hydrate reservoirs that may be conducive to energy production. The results of the GOM JIP Leg II LWD expedition are also being used to support the selection of sites for a future drilling, logging, and coring program. Operationally, recent drilling programs, such as ODP Leg 204, IODP Expedition 311, the Japanese Toaki-oki to Kumano-nada drilling leg, the Indian NGHP Expedition 01, and the South Korean Gas Hydrate Research and Development Organization Expedition 01 have demonstrated the great benefit of a multi-leg drilling approach, including the initial acquisition of LWD data that was used to then select sites for the drilling of complex core and wireline logging test holes. It is obvious that a fully integrated site selection approach and a “goal based” operational plan, possibly including numerous drill sites and drilling legs, are required considerations for any future gas hydrate research project.

Runnegar, B.

2004-12-01

Access to unweathered and uncontaminated samples of the least altered, oldest, sedimentary rocks is essential for understanding the early history of life on Earth and the environments in which it may have existed. For this reason, the NASA Astrobiology Institute (NAI) has embarked on two international programs, a series of Field Workshops aimed at making the most important surface samples available to investigators, and the Astrobiology Drilling Program (ADP), which serves to provide access to fresh subsurface samples when the scientific objectives require them. The Astrobiology Drilling Program commenced in Western Australia in 2003 with the initiation of its first project, the Archean Biosphere Drilling Project (ABDP). Funding for the ABDP came mainly from the Japanese Government through Kagoshima University and from NASA through the NAI Team at Pennsylvania State University, but significant technical and logistic support was provided by the Geological of Western Australia and, to a lesser extent, by the University of Western Australia. Six diamond drill cores totalling 1.4 km were obtained from astrobiologically important successions in the 3.3-3.5 Ga-old Pilbara Craton of northern Western Australia. Drilling in 2004 also occurred in Western Australia. The Deep Time Drilling Project (DTDP), a spin-off from the NAI's Mission to Early Earth Focus Group, completed one long hole, aimed mainly at fossil biomolecules (biomarkers) and other geochemical indicators of early life. The DTDP and the ABDP also jointly drilled two other important holes 2004, one through the oldest known erosion surface (and possible soil profile). The other intersected well-preserved middle Archean sediments. These efforts parallel other drilling initiatives within the wider astrobiological community that are taking place in Western Australia, South Africa, Spain, and arctic Canada. The ADP is managed by the NAI through a Steering Committee appointed by the NAI Director. Samples of cores obtained through ADP projects are available to the whole community, following a one year embargo, upon application to project PIs and the ADP Steering Committee.

Beyond 2013 - The Future of European Scientific Drilling Research - An introduction.

NASA Astrophysics Data System (ADS)

Camoin, G.; Stein, R.

2009-04-01

The Integrated Ocean Drilling Program (IODP) is funded for the period 2003-2013, and is now starting to plan the future of ocean drilling beyond 2013, including the development of new technologies, new emerging research fields as and the societal relevance of this programme. In this context an interdisciplinary and multinational (USA, Europe, Japan, Asian and Oceanian countries), key conference - INVEST IODP New Ventures in Exploring Scientific Targets - addressing all international IODP partners is therefore planned for September 23rd-25th 2009 in Bremen, Germany (more information at http://www.iodp.org and http://marum.de/iodp-invest.html) to discuss future directions of ocean drilling research and related aspects such as ventures with related programmes or with industry. The first critical step of INVEST is to define the scientific research goals of the second phase of the Integrated Ocean Drilling Program (IODP), which is expected to begin in late 2013. INVEST will be open to all interested scientists and students and will be the principal opportunity for the international science community to help shape the future of scientific ocean drilling. The outcome of the conference will be the base to draft a science plan in 2010 and to define new goals and strategies to effectively meet the challenges of society and future ocean drilling. The current EGU Session and the related two days workshop which will be held at the University of Vienna will specifically address the future of European scientific drilling research. The major objectives of those two events are to sharpen the European interests in the future IODP and to prepare the INVEST Conference and are therefore of prime importance to give weight to the European propositions in the program renewal processes, both on science, technology and management, and to provide the participants with information about the status/process of ongoing discussions and negotiations regarding program structure, and provide them with the expected framework (available drilling platforms and anticipated funding levels). The key items that should be addressed during the EGU Session and the workshop will especially include : (1) The future of ECORD (science, technology, management). (2) New research initiatives and emerging fields in scientific drilling (3) Relationships between IODP and other programs (e.g. ICDP, IMAGES etc). (4) Collaboration between academia and industry. (5) New technologies and the Mission Specific Platform approach.

The next stage was the Ocean Drilling Program (ODP) launched in 1985 with a new drill ship, the JOIDES Resolution. The exploration of the ocean seafloor continued, between 2003 and 2013, through the Integrated Ocean Drilling Program (IODP). During that time, in addition to the JOIDES Resolution, operated by the US, the scientists had at their service the Chikyu, operated by Japan, and Mission-Specific-Platforms, funded and implemented by the European Consortium for Ocean Research Drilling. Currently, scientific ocean drilling continues through the collaboration of scientists from 25 nations within the International Ocean Discovery Program (IODP). Over the last 50 years, the scientific ocean drilling expeditions conducted by these programmes have drilled and cored more than 3500 holes. The numerous sediment and rock samples recovered from the ocean floor have provided important insight on the active biological, chemical, and geological processes that have shaped the Earth over millions of years. During an expedition, once the 9.5-meter long cores arrive from the seafloor, the technicians label and cut them into 1.5-meter sections. Next, the shipboard scientists perform several analysis using non-destructive methods. Afterward, the technicians split the cores into two halves, the "working half", which scientists sample and use aboard the drilling platform, and the "archive half", which is kept in untouched condition after being visually described and photographed with a digital imaging system. The shipboard photographer also takes several close-up pictures of the archive-half core sections. This work presents some examples of how teachers can use DSDP/ODP/IODP core photographs and digital images, available through the Janus and LIMS online databases, to develop inquiry-based learning activities for secondary level students.

Much additional ground water could be obtained from both the "Alta Loma" sand and the upper part of the Beaumont clay, especially in the northern and western parts of the county. Before large developments of supplies are planned, however, these areas should be explored by test drilling. The problems of well spacing and pumping rates should be thoroughly studied in order to determine the maximum development permitted by the ground-water supply. Current observations should be continued with special emphasis on the progress of salt-water encroachment.

Initial Results from the New Stress Map of Texas Project

NASA Astrophysics Data System (ADS)

Lund Snee, J. E.; Zoback, M. D.

2015-12-01

Modern techniques for characterizing tectonic stress orientation and relative magnitude have been successfully used for more than 35 years. Nevertheless, large areas of North America lack high spatial resolution maps of stress orientation, magnitude, and faulting regime. In Texas, for example, <30 A-C-quality stress orientations are currently registered on the World Stress Map and only 7 of these points also describe the stress regime. Stress data are foundational elements of attempts to characterize tectonic driving forces, understand hazards associated with induced seismicity, and optimize production of oil, gas, and geothermal resources. This year, we launched the Texas Stress Map project to characterize tectonic stress patterns at higher spatial resolution across Texas and nearby areas. Following a successful effort just completed in Oklahoma, we will evaluate borehole breakouts, drilling-induced tensile fractures, shear wave anisotropy, and earthquake data. The principal data source will be FMI (fullbore formation microimager), UBI (ultrasonic borehole imager), cross-dipole sonic, density, and caliper logs provided by private industry. Earthquake moment tensor solutions from the U.S. Geological Survey, Saint Louis University and other sources will also be used. Our initial focus is on the Permian Basin and Barnett Shale petroleum plays due to the availability of data, but we will expand our analysis across the state as the project progresses. In addition, we hope to eventually apply the higher spatial resolution data coverage to understanding tectonic and geodynamic characteristics of the southwestern United States and northeastern Mexico. Here we present early results from our work to constrain stress orientations and faulting regime in and near Texas, and we also provide a roadmap for the ongoing research.

SMALLER FOOTPRINT DRILLING SYSTEM FOR DEEP AND HARD ROCK ENVIRONMENTS; FEASIBILITY OF ULTRA-HIGH SPEED DIAMOND DRILLING

DOE Office of Scientific and Technical Information (OSTI.GOV)

Alan Black; Arnis Judzis

2004-10-01

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high (greater than 10,000 rpm) rotational speeds. The work includes a feasibility of concept research effort aimed at development and test results that will ultimately result in the ability to reliably drill ''faster and deeper'' possibly with rigs having a smaller footprint to be more mobile. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration rockmore » cutting with substantially lower inputs of energy and loads. The project draws on TerraTek results submitted to NASA's ''Drilling on Mars'' program. The objective of that program was to demonstrate miniaturization of a robust and mobile drilling system that expends small amounts of energy. TerraTek successfully tested ultrahigh speed ({approx}40,000 rpm) small kerf diamond coring. Adaptation to the oilfield will require innovative bit designs for full hole drilling or continuous coring and the eventual development of downhole ultra-high speed drives. For domestic operations involving hard rock and deep oil and gas plays, improvements in penetration rates is an opportunity to reduce well costs and make viable certain field developments. An estimate of North American hard rock drilling costs is in excess of $1,200 MM. Thus potential savings of $200 MM to $600 MM are possible if drilling rates are doubled [assuming bit life is reasonable]. The net result for operators is improved profit margin as well as an improved position on reserves. The significance of the ''ultra-high rotary speed drilling system'' is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm--usually well below 5,000 rpm. This document details the progress to date on the program entitled ''SMALLER FOOTPRINT DRILLING SYSTEM FOR DEEP AND HARD ROCK ENVIRONMENTS; FEASIBILITY OF ULTRA-HIGH SPEED DIAMOND DRILLING'' for the period starting June 23, 2003 through September 30, 2004. TerraTek has reviewed applicable literature and documentation and has convened a project kick-off meeting with Industry Advisors in attendance. TerraTek has designed and planned Phase I bench scale experiments. Some difficulties in obtaining ultra-high speed motors for this feasibility work were encountered though they were sourced mid 2004. TerraTek is progressing through Task 3 ''Small-scale cutting performance tests''. Some improvements over early NASA experiments have been identified.« less

Sub-Ocean Drilling

NASA Technical Reports Server (NTRS)

1981-01-01

The National Science Foundation (NSF) initialized a new phase of exploration last year, a 10 year effort jointly funded by NSF and several major oil companies, known as the Ocean Margin Drilling Program (OMDP). The OMDP requires a ship with capabilities beyond existing drill ships; it must drill in 13,000 feet of water to a depth 20,000 feet below the ocean floor. To meet requirements, NSF is considering the conversion of the government-owned mining ship Glomar Explorer to a deep ocean drilling and coring vessel. Feasibility study performed by Donhaiser Marine, Inc. analyzed the ship's characteristics for suitability and evaluated conversion requirement. DMI utilized COSMIC's Ship Motion and Sea Load Computer program to perform analysis which could not be accomplished by other means. If approved for conversion, Glomar Explorer is expected to begin operations as a drillship in 1984.

Estimating gas kick arrival to better manage surface flow

DOE Office of Scientific and Technical Information (OSTI.GOV)

Merryman, J.

1997-06-01

There are many quality, expertly designed programs for teaching rig crews prevention and control of well kicks. Much time and money has been spent training rig crews for procedures and methods to avoid kicks, and what to do if you have one, even though all accepted practices were followed. One false/bad result from this training is that individuals have come away from this training believing that once a gas kick is circulated through the choke, all problems are simple and manageable, i.e., the danger has passed. What you do with gas once it is downstream of the choke has notmore » been given enough emphasis in some training programs, including the one the author is involved in. This article, prepared from experiences on actual rig locations in Wyoming and Argentina, and developed for well control training in Parker Drilling Co.`s Training Center, Odessa, Texas, describes a method for estimating the time, in pump strokes and/or minutes, for a gas kick to reach surface. Reducing pump strokes (circulating flowrate) and knowing available time to gas kick arrival allows the crew to prepare surface handling equipment. Common misconceptions about gas handling and potential resulting problems are noted. An example calculation describes the calculation procedure.« less

Technology Development and Field Trials of EGS Drilling Systems at Chocolate Mountain

DOE Data Explorer

Steven Knudsen

2012-01-01

Polycrystalline diamond compact (PDC) bits are routinely used in the oil and gas industry for drilling medium to hard rock but have not been adopted for geothermal drilling, largely due to past reliability issues and higher purchase costs. The Sandia Geothermal Research Department has recently completed a field demonstration of the applicability of advanced synthetic diamond drill bits for production geothermal drilling. Two commercially-available PDC bits were tested in a geothermal drilling program in the Chocolate Mountains in Southern California. These bits drilled the granitic formations with significantly better Rate of Penetration (ROP) and bit life than the roller cone bit they are compared with. Drilling records and bit performance data along with associated drilling cost savings are presented herein. The drilling trials have demonstrated PDC bit drilling technology has matured for applicability and improvements to geothermal drilling. This will be especially beneficial for development of Enhanced Geothermal Systems whereby resources can be accessed anywhere within the continental US by drilling to deep, hot resources in hard, basement rock formations.

Lack of training threatening drilling talent supply

When oil prices crashed in the mid-1980s, the industry tightened budgets. Among the austerity measures taken to survive the consequences of low product prices was an end to expensive, long-term investment training of drilling engineers. In the absence of traditional sources of trained drilling talent, forward-looking contractors are creating their own training programs. The paper describes the activities of some companies who are setting up their own training programs, and an alliance being set up by Chevron and Amoco for training. The paper also discusses training drilling managers, third-party trainers, and the consequences for the industry that does not renewmore » its inventory of people.« less

Towards a distributed infrastructure for research drilling in Europe

NASA Astrophysics Data System (ADS)

Mevel, C.; Gatliff, R.; Ludden, J.; Camoin, G.; Horsfield, B.; Kopf, A.

2012-04-01

The EC-funded project "Deep Sea and Sub-Seafloor Frontier" (DS3F) aims at developing seafloor and sub seafloor sampling strategies for enhanced understanding of deep-sea and sub seafloor processes by connecting marine research in life and geosciences, climate and environmental change, with socio-economic issues and policy building. DS3F has identified access to sub seafloor sampling and instrumentation as a key element of this approach. There is a strong expertise in Europe concerning direct access to the sub seafloor. Within the international program IODP (Integrated Ocean Drilling Program), ECORD (European Consortium for Ocean Research Drilling) has successfully developed the concept of mission specific platforms (MSPs), contracted on a project basis to drill in ice covered and shallow water areas. The ECORD Science Operator, lead by the British Geological Survey (BGS) has build a internationally recognized expertise in scientific ocean drilling, from coring in challenging environment, through down hole measurements and laboratory analysis to core curation and data management. MARUM, at the Bremen University in Germany, is one of the three IODP core repositories. Europe is also at the forefront of scientific seabed drills, with the MeBo developed by MARUM as well as the BGS seabed rocks drills. Europe also plays a important role in continental scientific drilling and the European component of ICDP (International Continental Scientific Drilling Program) is strengthening, with the recent addition of France and foreseen addition of UK. Oceanic and continental drilling have very similar scientific objectives. Moreover, they share not only common technologies, but also common data handling systems. To develop an integrated approach to technology development and usage, a move towards a a distributed infrastructure for research drilling in Europe has been initiated by these different groups. Built on existing research & operational groups across Europe, it will facilitate the sharing of technological and scientific expertise for the benefit of the science community. It will link with other relevant infrastructure initiatives such as EMSO (European Marine Seafloor Observatories). It will raise the profile of scientific drilling in Europe and hopefully lead to better funding opportunities.

1994-01-01

Coal test drilling in the Thar Desert of southeast Pakistan was conducted as part of the Coal Exploration and Assessment Program (COALREAP) involving the United States Agency for International Development (USAID), the Geological Survey of Pakistan (GSP), and the U.S. Geological Survey. Drilling was performed in the Thar Desert, or Great Indian Desert, approximately 175 km northeast of Karachi. Twenty five exploration holes were drilled between January 1992 and May 1994. Drill core was described by geologists of the Pakistan Geological Survey and coal samples were analyzed in both the United States and Pakistan. U.S. Geological Survey geologists offered technical assistance, trained GSP personnel, and managed the drilling program according to an agreement with USAID under the Energy Planning and Development Project.Drilling was performed by the Geological Survey of Pakistan. During drilling, the first 50 m was rotary drilled and cuttings collected every 2 m for examination. Average depth for all coal beds is 214 m with a total average thickness of 10 m of coal per drill hole. Core was described, boxed, and stored at the Geological Survey of Pakistan core library at Sonda, near Hyderabad. Approximately 6,412 m of Paleocene to Eocene rock was drilled of which 3,990 m was cored and 1,113 m was rotary drilled.There was 1,309 m of core loss. Geophysical logging of each drill hole permitted detailed thicknesses of coal to be determined. Analysis of the coal indicated a rank of lignite B with an as-received heating value over 5,000 Btu.This report presents data collected at the drill sites and should be used inconjunction with the published interpretive report (Fassett and Durrani, 1994) and the USGS Open-File Report 94-167, which contains analysis of the coal samples. Tables provide quick reference to numeric data and results. Detailed index maps and specific data, for each drill hole are included. This report covers drill holes TP-5 to TP-31. Drill holes TP-16, 17, 21, 26, 27, and 29 were planned but not drilled due to time restraints and (or) a determination that those drill sites were not needed to effectively delineate the coal deposit. The basic data for drill holes TP-1 through TP-4 are included in SanFilipo and others, 1994 however, some data for these drill holes are included for consistency.

Rowan Gorilla I rigged up, heads for eastern Canada

DOE Office of Scientific and Technical Information (OSTI.GOV)

Not Available

1984-03-01

Designed to operate in very hostile offshore environments, the first of the Rowan Gorilla class of self-elevating drilling rigs has been towed to its drilling assignment offshore Nova Scotia. About 40% larger than other jackups, these rigs can operate in 300 ft of water, drilling holes as deep as 30,000 ft. They also feature unique high-pressure and solids control systems that are expected to improve drilling procedures and efficiencies. A quantitative formation pressure evaluation program for the Hewlett-Packard HP-41 handheld calculator computes formation pressures by three independent methods - the corrected d exponent, Bourgoyne and Young, and normalized penetration ratemore » techniques for abnormal pressure detection and computation. Based on empirically derived drilling rate equations, each of the methods can be calculated separately, without being dependent on or influenced by the results or stored data from the other two subprograms. The quantitative interpretation procedure involves establishing a normal drilling rate trend and calculating the pore pressure from the magnitude of the drilling rate trend or plotting parameter increases above the trend line. Mobil's quick, accurate program could aid drilling operators in selecting the casing point, minimizing differential sticking, maintaining the proper mud weights to avoid kicks and lost circulation, and maximizing penetration rates.« less

Land subsidence associated with hydrocarbon production, Texas Gulf Coast

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kreitler, C.W.; White, W.A.; Akhter, M.S.

1988-01-01

Although ground-water withdrawal has been the predominant cause of land subsidence in the Texas Gulf Coast, localized subsidence and faulting have also resulted from hydrocarbon production. Subsidence was documented as early as the 1920s over the Goose Creek field. Since then, subsidence and/or faulting have been identified over the Saxet, South Houston, Chocolate Bayou, Hastings, Alco-Mag, Clinton, Mykawa, Blue Ridge, Webster, and Caplen oil fields. Oil-production-related subsidence over these fields generally creates few environmental or engineering problems. One exception is the subsidence and faulting over the Caplen oil field on Bolivar Peninsula, where more than 1,000 ac of saltwater marshmore » has been replaced by subaqueous flats. Subsidence may be occurring over other fields but has not been identified because of limited releveled benchmark data. An evaluation of drill-stem and bottom-hole pressure data for the Frio Formation in Texas indicates extensive depressurization presumably from hydrocarbon production. Nearly 12,000 measurements from a pressure data base of 17,000 measurements indicate some depressurization. Some of the Frio zones have pressure declines of more than 1,500 psi from original hydrostatic conditions. Subsidence and faulting may be associated with these fields in the Frio as well as other Tertiary formations where extensive hydrocarbon production and subsequent depressurization have occurred.« less

Ozone impacts of natural gas development in the Haynesville Shale.

PubMed

Kemball-Cook, Susan; Bar-Ilan, Amnon; Grant, John; Parker, Lynsey; Jung, Jaegun; Santamaria, Wilson; Mathews, Jim; Yarwood, Greg

2010-12-15

The Haynesville Shale is a subsurface rock formation located beneath the Northeast Texas/Northwest Louisiana border near Shreveport. This formation is estimated to contain very large recoverable reserves of natural gas, and during the two years since the drilling of the first highly productive wells in 2008, has been the focus of intensive leasing and exploration activity. The development of natural gas resources within the Haynesville Shale is likely to be economically important but may also generate significant emissions of ozone precursors. Using well production data from state regulatory agencies and a review of the available literature, projections of future year Haynesville Shale natural gas production were derived for 2009-2020 for three scenarios corresponding to limited, moderate, and aggressive development. These production estimates were then used to develop an emission inventory for each of the three scenarios. Photochemical modeling of the year 2012 showed increases in 2012 8-h ozone design values of up to 5 ppb within Northeast Texas and Northwest Louisiana resulting from development in the Haynesville Shale. Ozone increases due to Haynesville Shale emissions can affect regions outside Northeast Texas and Northwest Louisiana due to ozone transport. This study evaluates only near-term ozone impacts, but the emission inventory projections indicate that Haynesville emissions may be expected to increase through 2020.

Assessment of continuous oil resources in the Wolfcamp shale of the Midland Basin, Permian Basin Province, Texas, 2016

USGS Publications Warehouse

Gaswirth, Stephanie B.

2017-03-06

The U.S. Geological Survey completed a geology-based assessment of undiscovered, technically recoverable continuous petroleum resources in the Wolfcamp shale in the Midland Basin part of the Permian Basin Province of west Texas. This is the first U.S. Geological Survey evaluation of continuous resources in the Wolfcamp shale in the Midland Basin. Since the 1980s, the Wolfcamp shale in the Midland Basin has been part of the “Wolfberry” play. This play has traditionally been developed using vertical wells that are completed and stimulated in multiple productive stratigraphic intervals that include the Wolfcamp shale and overlying Spraberry Formation. Since the shift to horizontal wells targeting the organic-rich shale of the Wolfcamp, more than 3,000 horizontal wells have been drilled and completed in the Midland Basin Wolfcamp section. The U.S. Geological Survey assessed technically recoverable mean resources of 20 billion barrels of oil and 16 trillion cubic feet of associated gas in the Wolfcamp shale in the Midland Basin.

How PEMEX engineered a deep well completion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Antimo A., J.C.

1971-09-01

Completion and testing of Petroleos Mexicano's W. Reynosa Well No. 1 in the NE. Frontier District south of the Texas border required engineering innovation to combat the 375/sup 0/F temperatures and pressures near 18,000 psi. Drilled to nearly 18,000 ft, the well was completed and tested below 17,000 ft. Completion plans were designed to determine the economic importance of the reservoir and to provide information and experience in planning future completions to 20,000 ft and deeper. Interval selection was based in part on data acquired during drilling, including lithology, geologic age, rock characteristics, and sensitivity to damage caused by drillingmore » fluids. A set of logs was obtained and evaluated by computer in correlation with mud-log and pressure data. The logs also were correlated with logs from other wells in the area. Pressure gradients in the Reynosa field indicated the possibility of pressures on the order of 10,000 psi, and required the use of specially designed valves rated to 20,000 psi, in conjunction with a casinghead that would permit drilling to the projected depth. A choke manifold consisted of an interchangeable, manually operated positive choke and a set of automatic adjustable chokes.

Scientific Ocean Drilling: A Legacy of ODP Education and Community Engagement by JOI/USSSP

NASA Astrophysics Data System (ADS)

Johnson, A.; Cortes, M.; Farrell, J. W.

2003-12-01

The U.S. Science Support Program (USSSP) was established in 1986 to support the participation of U.S. scientists in the international Ocean Drilling Program (ODP). Since inception, USSSP has been managed by Joint Oceanographic Institutions (JOI), through a cooperative agreement with NSF, and guided by the U.S. Science Advisory Committee (USSAC). One of USSSP's primary goals has been to enhance the scientific contribution of ocean drilling and to maintain its vitality through a broad range of education and outreach activities. USSSP's first educational program, the Schlanger Ocean Drilling Fellowship, was established to encourage doctoral candidates to conduct research aboard the ODP drill ship, JOIDES Resolution. Since 1987, 74 fellowships have been awarded and the program has been expanded to include shorebased ODP-related research and Masters degree candidates. USSSP's second major educational activity is the Distinguished Lecturer Series. To date, 70 scientists have spoken about their ODP research at 334 institutions, effectively reaching new and diverse educational communities. In addition, USSSP has developed and distributed two interactive educational CD-ROMs (ODP: Mountains to Monsoons and Gateways to Glaciation) and an educational poster (Blast from the Past). All three items are popular supplements in classrooms from middle school to college because they present accessible scientific content, demonstrate the scientific method, and illustrate the collaborative and international nature of scientific research. USSSP's outreach efforts have included publishing the JOI/USSAC Newsletter since 1988 and ODP's Greatest Hits (abstracts written by U.S. scientists). The latter is broadly used because it communicates exciting scientific results in lay terms. USSSP has sponsored other educational efforts including a workshop to seek recommendations for educational activities to be associated with future scientific ocean drilling. NSF is currently considering the response to their solicitation of proposals to manage a successor program to USSSP, which will support the involvement of U.S. scientists in the new Integrated Ocean Drilling Program. The educational and outreach component of the new USSSP will target students at all levels, building upon improving on the USSSP-ODP achievements.

Optimizing Geothermal Drilling: Oil and Gas Technology Transfer

Denninger, Kate; Eustes, Alfred; Visser, Charles

There is a significant amount of financial risk associated with geothermal drilling. This study of drilling operations seeks opportunities to improve upon current practices and technologies. The scope of this study included analyzing 21 geothermal wells and 21 oil and gas wells. The goal was to determine a 'Perfect Well' using historical data to compare the best oil and gas well to the best geothermal well. Unfortunately, limitations encountered in the study included missing data (bit records, mud information, etc.) and poor data collection practices An online software database was used to format drilling data to IADC coded daily drillingmore » reports and generate figures for analysis. Six major issues have been found in geothermal drilling operations. These problems include lost circulation, rig/ equipment selection, cementing, penetration rate, drilling program, and time management. As a result of these issues, geothermal drilling averaged 56.4 days longer than drilling comparable oil and gas wells in the wells in this study. Roughly $13.9 million was spent on non-productive time in the 21 geothermal wells, compared with only $1.3 million in the oil and gas wells, assuming a cost of $50,000 per day. Comparable events such as drilling the same sized hole, tripping in/out, cementing, and running the same size casing took substantially less time in the oil and gas wells. Geothermal wells were drilled using older and/or less advanced technology to depths less than 10,000 feet, while oil and gas wells reached 12,500 feet faster with purpose built rigs. A new approach is now underway that will optimize drilling programs throughout the drilling industry using Mechanical Specific Energy (MSE) as a tool to realize efficient drilling processes. Potential improvements for current geothermal operations are: the use of electronic records, real time services, and official glossary terms to describe rig operations, and advanced drilling rigs/technology.« less

Key catalysts for Marcellus Shale drilling in New York were identified. New York remains the only state in the nation with a legislative moratorium on high-volume hydraulic fracturing, as regulators and state lawmakers work to balance the advantages of potential economic benefits while protecting public drinking water resources and the environment. New York is being particularly careful to work on implementing sufficiently strict regulations to mitigate the environmental impacts Pennsylvania has already seen, such as methane gas releases, fracturing fluid releases, flowback water and brine controls, and total dissolved solids discharges. In addition to economic and environmental lessons learned, themore » New York Department of Environmental Conservation (DEC) also acknowledges impacts to housing markets, security, and other local issues, and may impose stringent measures to mitigate potential risks to local communities. Despite the moratorium, New York has the opportunity to take advantage of increased capital investment, tax revenue generation, and job creation opportunities by increasing shale gas activity. The combination of economic benefits, industry pressure, and recent technological advances will drive the pursuit of natural gas drilling in New York. We identify four principal catalysts as follows: Catalyst 1: Pressure from Within the State. Although high-volume hydraulic fracturing has become a nationally controversial technology, shale fracturing activity is common in every U.S. state except New York. The regulatory process has delayed potential economic opportunities for state and local economies, as well as many industry stakeholders. In 2010, shale gas production accounted for $18.6 billion in federal royalty and local, state, and federal tax revenues. (1) This is expected to continue to grow substantially. The DEC is under increased pressure to open the state to the same opportunities that Alabama, Arkansas, California, Colorado, Kansas, Louisiana, Montana, New Mexico, North Dakota, Ohio, Oklahoma, Pennsylvania, South Dakota, Texas, Utah, West Virginia, and Wyoming are pursuing. Positive labor market impacts are another major economic draw. According to the Revised Draft SGEIS on the Oil, Gas and Solution Mining Regulatory Program (September 2011), hydraulic fracturing would create between 4,408 and 17,634 full-time equivalent (FTE) direct construction jobs in New York State. Indirect employment in other sectors would add an additional 29,174 FTE jobs. Furthermore, the SGEIS analysis suggests that drilling activities could add an estimated $621.9 million to $2.5 billion in employee earnings (direct and indirect) per year, depending upon how much of the shale is developed. The state would also receive direct tax receipts from leasing land, and has the potential to see an increase in generated indirect revenue. Estimates range from $31 million to $125 million per year in personal income tax receipts, and local governments would benefit from revenue sharing. Some landowner groups say the continued delay in drilling is costing tens of thousands of jobs and millions of dollars in growth for New York, especially in the economically stunted upstate. A number of New York counties near Pennsylvania, such as Chemung, NY, have experienced economic uptick from Pennsylvania drilling activity just across the border. Chemung officials reported that approximately 1,300 county residents are currently employed by the drilling industry in Pennsylvania. The Marcellus shale boom is expected to continue over the next decade and beyond. By 2015, gas drilling activity could bring 20,000 jobs to New York State alone. Other states, such as Pennsylvania and West Virginia, are also expected to see a significant increase in the number of jobs. Catalyst 2: Political Reality of the Moratorium. Oil and gas drilling has taken place in New York since the 19th century, and it remains an important industry with more than 13,000 currently active wells. The use of hydraulic fracturing in particular has been employed for decades. Yet, as technological advancements have enabled access to gas in areas where drilling is not common practice, public concern has ballooned. Opponents argue that more oversight is necessary to protect the environment and public health, while supporters believe the industry is already adequately regulated. Although it is important for New York to complete a thorough environmental and regulatory review, an extended ban could lead to litigation by property owners who have been stripped of the ability to lease their mineral rights. Other states are moving forward by implementing legislative guidelines or rules created by commissions to ensure that resources are developed safely. One of the most controversial issues in other states to date has revolved around the public disclosure of chemical additives in drilling fluid. While the industry is hesitant to reveal trade secrets, the public and many officials want the security of knowing what chemicals are pumped into the ground. Industry transparency could help mitigate the public concern and controversy that is delaying a lift of the moratorium. Currently, at least five other states have set chemical disclosure rules. Arkansas, Michigan, Montana, Texas, and Wyoming require disclosure of the chemical components of drilling fluid. Colorado has the most stringent rules, requiring not just the disclosure of the additives but of their concentrations as well. As more states continue to allow hydraulic fracturing, New York will likely lift the moratorium and instead implement more stringent regulations that help to alleviate public concern surrounding hydraulic fracturing. This will allow the state to safely pursue the expansive opportunities offered by the Marcellus shale without falling behind economically. Catalyst 3: Energy and Infrastructure Benefits. Natural gas provides a key source of energy in the Northeast. The DEC estimates the Marcellus shale gas resource potential to be between 168-516 Tcf. Even at the low end of this range, Marcellus alone could supply seven years of total U.S. energy consumption, and it would provide a local resource for New York. One report suggests that savings from lower natural gas costs would result in an average annual savings of $926 per household. (4) Industry growth is leading to lower natural gas and electric power prices, while decreasing reliance on Liquid Natural Gas (LNG) imports and enhancing domestic energy security. This makes development of the resources an even more attractive commitment to New York. In addition, the natural gas business is predominantly regional in scope. Drilling companies would be required to build new pipelines for gas development in New York, therefore State regulators face valuable ancillary benefits of natural gas development such as infrastructure improvements. Catalyst 4: Technology Improvements. Lastly, the moratorium itself does not prevent the use of alternative drilling technologies, such as non-hydraulic fracturing, for shale gas production. Developers are already using new systems in Texas and Canada, as well as in France where hydraulic fracturing is banned country-wide. Commercial viability of these new technologies could ultimately provide an alternative to jumpstart shale drilling in New York if necessary. The potential benefits from development of the Marcellus shale in New York are undeniable, though regulators are still working to balance the need to stimulate the economy with environmental protection and public health. Since closing the public comment period in January, the DEC has signaled that much more work is needed, making no promises to near-term completion. While, neighboring states are feeling the economic benefits of drilling, the political environment and the recession continues adding pressure to the process in New York state.« less

A Broadband Investigation of the Texas/Gulf of Mexico Passive Margin

The lithosphere of central and east Texas underwent two cycles of continental rifting and orogeny from the formation of Laurentia and assembly through the breakup of Pangea. The craton itself, exposed in the Llano uplift of central Texas, formed ~1.4 Ga as part of the great expanse of Mesoproterozoic crust that makes up southern Laurentia. Some of this crust was deformed during the Grenville orogeny ~1.1 Ga. Southern Laurentia was subsequently stable until rifting began in Cambrian time (~530 Ma). Suturing of Gondwana to Laurentia (310-290 Ma) during the assembly of Pangea formed the Ouachita orogen in west Texas. Sometime before 200 Ma rifting was initiated, opening the Gulf of Mexico (GoM). In north and east Texas the Ouachita front lies north of GoM rifting but, according to deep seismic data, Ouachita structures appear to coincide with GoM rifting in south and central Texas. This suggests that rifting in that region occurred along structures that were weakened previously by Ouachita deformation and reactivated during the Jurassic opening of the GoM. It is not clear whether the process that created the Gulf of Mexico and led to the formation of Texas' Gulf Coast Plain (GCP) is best described as "active" or "passive" rifting. A recent study interpreted the GCP to be a volcanic rifted margin—an active rifting process—using available gravity, magnetic, drilling and geological data, but older studies describe the opening of the GoM as a passive event. In the coastal plain, a large magnetic anomaly suggests that the crust here was modified by volcanism. Seismic data are sparse and of limited quality in the Gulf Coast region so we conducted a 2.5-year broadband seismograph transect across the GCP in an effort to clarify its structure and origin. In all, twenty-three broadband seismographs were deployed in a line from Matagorda Island, in the Gulf of Mexico, to Johnson City, TX, on the uplifted Llano Plateau from July 2010 to December 2012. These seismographs have an average spacing of 15 km and coincided with the deployment of EarthScope Transportable Array stations in central and east Texas. We will present the results of P- and S-wave tomographic inversions for upper mantle structure beneath the array.

Hundreds of Cruises, Thousands of People, Endless Discoveries - Education and Outreach in the Integrated Ocean Drilling Program

NASA Astrophysics Data System (ADS)

Peart, L.; Niemitz, M.; Boa, S.; Corsiglia, J.; Klaus, A.; Petronotis, K.; Iturrino, G.

2005-12-01

For 37 years, scientific ocean drilling programs have sponsored hundreds of expeditions, drilled at over 1,800 sites and recovered over 200 miles of core. The discoveries of these programs have led to important realizations of how our earth works. Past expeditions have validated the theory of plate tectonics, provided unparalleled ancient climate records and recovered evidence of the asteroid impact that wiped out the dinosaurs 65 million years ago - and new discoveries occur with every expedition. By producing education materials and programs and encouraging mass media journalists' interest in our news, we strive to fulfill our commitment to communicate our programs' scientific discoveries to the public, in a way that people - not just other scientists - understand. With the advent of the Integrated Ocean Drilling Program (IODP), education and outreach efforts have expanded to pursue new opportunities and engage wider audiences. Through our strategy of Teaching for Science, Learning for LifeTM, our education efforts seek to utilize the interdisciplinary nature of scientific ocean drilling to teach career awareness, scientific methods, teamwork, and problem solving techniques for a lifetime of learning, decision making and good citizenship. In pursuit of this goal, we have implemented professional and resource development programs and expanded our outreach at education-focused conferences to help teachers use IODP science to satiate the student's need to learn the methods of science that apply to everyday life. We believe that this message also applies to life-long learners and thus we have focused our efforts on news media outreach and education opportunities surrounding ports of call of the JOIDES Resolution, permanent and traveling museum exhibits. In addition, our outreach to undergraduate and graduate audiences, through a lecture series, research fellowships and internships, helps to create future generations of science leaders.

Sass, J.H.; Elders, W.A.

1986-01-01

The Salton Sea Scientific Drilling Project, was spudded on 24 October 1985, and reached a total depth of 10,564 ft. (3. 2 km) on 17 March 1986. There followed a period of logging, a flow test, and downhole scientific measurements. The scientific goals were integrated smoothly with the engineering and economic objectives of the program and the ideal of 'science driving the drill' in continental scientific drilling projects was achieved in large measure. The principal scientific goals of the project were to study the physical and chemical processes involved in an active, magmatically driven hydrothermal system. To facilitate these studies, high priority was attached to four areas of sample and data collection, namely: (1) core and cuttings, (2) formation fluids, (3) geophysical logging, and (4) downhole physical measurements, particularly temperatures and pressures.

Environmental effects monitoring at the Terra Nova offshore oil development (Newfoundland, Canada): Program design and overview

DeBlois, Elisabeth M.; Tracy, Ellen; Janes, G. Gregory; Crowley, Roger D.; Wells, Trudy A.; Williams, Urban P.; Paine, Michael D.; Mathieu, Anne; Kilgour, Bruce W.

2014-12-01

An environmental effects monitoring (EEM) program was developed by Suncor (formerly Petro-Canada) in 1997/98 to assess effects of the Terra Nova offshore oil and gas development on the receiving environment. The Terra Nova Field is located on the Grand Banks approximately 350 km southeast of Newfoundland (Canada), at approximately 100 m water depth. The EEM program was developed with guidance from experts in government, academia and elsewhere, and with input from the public. The EEM program proposed by Suncor was accepted by Canadian regulatory agencies and the program was implemented in 2000, 2001, 2002, 2004, 2006, 2008 and 2010, with pre-development sampling in 1997. The program continues to be implemented every two years. EEM includes an assessment of alterations in sediment quality through examination of changes in sediment chemistry, particle size, toxicity and benthic invertebrate community structure. A second component of the program examines potential effects on two species of commercial fishing interest: Iceland scallop (Chlamys islandica) and American plaice (Hippoglossoides platessoides). Chemical body burden for these two species is examined and taste tests are performed to assess the presence of taint in edible tissues. Effects on American plaice bioindicators are also examined. A final component of the program assesses potential effects of the Terra Nova development on water quality and examines water column chemistry, chlorophyll concentration and physical properties. The papers presented in this collection focus on effects of drill cuttings and drilling muds on the seafloor environment and, as such, report results on sediment quality and bioaccumulation of drilling mud components in Iceland scallop and American plaice. This paper provides information on drilling discharges, an overview of the physical oceanography at the Terra Nova Field, and an overview of the field program designed to assess environmental effects of drilling at Terra Nova.

An Improved Approach for Forecasting Ecological Impacts from Future Drilling in Unconventional Shale Oil and Gas Plays.

Directional well drilling and hydraulic fracturing has enabled energy production from previously inaccessible resources, but caused vegetation conversion and landscape fragmentation, often in relatively undisturbed habitats. We improve forecasts of future ecological impacts from unconventional oil and gas play developments using a new, more spatially-explicit approach. We applied an energy production outlook model, which used geologic and economic data from thousands of wells and three oil price scenarios, to map future drilling patterns and evaluate the spatial distribution of vegetation conversion and habitat impacts. We forecast where future well pad construction may be most intense, illustrating with an example from the Eagle Ford Shale Play of Texas. We also illustrate the ecological utility of this approach using the Spot-tailed Earless Lizard (Holbrookia lacerata) as the focal species, which historically occupied much of the Eagle Ford and awaits a federal decision for possible Endangered Species Act protection. We found that ~17,000-45,500 wells would be drilled 2017‒2045 resulting in vegetation conversion of ~26,485-70,623 ha (0.73-1.96% of pre-development vegetation), depending on price scenario ($40-$80/barrel). Grasslands and row crop habitats were most affected (2.30 and 2.82% areal vegetation reduction). Our approach improves forecasts of where and to what extent future energy development in unconventional plays may change land-use and ecosystem services, enabling natural resource managers to anticipate and direct on-the-ground conservation actions to places where they will most effectively mitigate ecological impacts of well pads and associated infrastructure.

Shallow Aquifer Methane Gas Source Assessment

NASA Astrophysics Data System (ADS)

Coffin, R. B.; Murgulet, D.; Rose, P. S.; Hay, R.

2014-12-01

Shale gas can contribute significantly to the world's energy demand. Hydraulic fracturing (fracking) on horizontal drill lines developed over the last 15 years makes formerly inaccessible hydrocarbons economically available. From 2000 to 2035 shale gas is predicted to rise from 1% to 46% of the total natural gas for the US. A vast energy resource is available in the United States. While there is a strong financial advantage to the application of fracking there is emerging concern about environmental impacts to groundwater and air quality from improper shale fracking operations. Elevated methane (CH4) concentrations have been observed in drinking water throughout the United States where there is active horizontal drilling. Horizontal drilling and hydraulic-fracturing can increase CH4 transport to aquifers, soil and the vadose zone. Seepage can also result from casing failure in older wells. However, there is strong evidence that elevated CH4 concentrations can be associated with topographic and hydrogeologic features, rather than shale-gas extraction processes. Carbon isotope geochemistry can be applied to study CH4source(s) in shallow vadose zone and groundwater systems. A preliminary TAMU-CC isotope data set from samples taken at different locations in southern Texas shows a wide range of CH4 signatures suggesting multiple sources of methane and carbon dioxide. These data are interpreted to distinguish regions with methane contributions from deep-sourced horizontal drilling versus shallow system microbial production. Development of a thorough environmental assessment using light isotope analysis can provide understanding of shallow anthropogenic versus natural CH4sources and assist in identifying regions that require remedial actions.

Preston, Sandra; Barna, J. W.; Geiger, S.; Johnson, R.; Rimm, N.; Griffin, J.; Watson, K.

2008-05-01

McDonald Observatory can be a leader in Texas for the International Year of Astronomy (IYA09) celebration. Our strategy builds on the IYA09 program, tailoring it for the Texas audience, while also nationally promoting McDonald Observatory, UT Astronomy, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) and our partnership in the Giant Magellan Telescope (GMT). We will also use this opportunity to make a concentrated outreach effort toward the Hispanic and Spanish-speaking communities in Texas and the nation, aligning with the IYA09 objective for improving relations with underrepresented and minority populations. Fundraising is a key ingredient to our success in 2009 and the future. With NASA Office of Space Science funding for education and public outreach being rethought, we will be focusing on new sources for fundraising, including private donations and corporate sponsorship, augmented by planned giving. We will take advantage of the timing to raise funds for special IYA09 programs, as well as for our large telescope projects HETDEX and GMT, along with our endowment and planned giving programs for education, outreach, and research. We will work with the UT McCombs School of Business on corporate sponsorship. During this time we will also go through a branding experience that will visually unify McDonald Observatory, UT Astronomy, and the education and public outreach programs. A consistent brand that can be used on the website and other media is our goal to build a stronger public presence that will aid us in our fundraising efforts. A Public Relations Internship Project produced a report to help launch this process. We are working with the UT College of Communications Advertising Department and with Hill Strategic Brand Solutions in Houston, Texas. We hope that our efforts will produce Texas-sized results!

A critical review of existing innovative science and drilling proposals within IODP

NASA Astrophysics Data System (ADS)

Behrmann, J. H.

2009-04-01

In the present phase of the Integrated Ocean Drilling Program (IODP) activities are guided by the Initial Science Plan that identified three major themes: The Deep Biosphere and the Subseafloor Ocean; Environmental Change, Processes and Effects; and Solid Earth Cycles and Geodynamics. New initiatives and complex drilling proposals were developed that required major advances in drilling platforms and technologies, and expansion of the drilling community into new areas of specialization. The guiding themes in the Initial Science Plan are instrumental for the proposal development and evaluation, and will continue to represent the goals of IODP until 2013. A number of innovative and highly ranked individual proposals and coordinated sets of proposals ready to be drilled has been forwarded by the Science Planning Committee (SPC) to the IODP Operations Task Force (OTF) for scoping, planning and scheduling. For the Deep Biosphere theme these include proposals to drill targets in the Central Atlantic, the Okinawa Trough, and the Southern Pacific. The Environmental Change, Processes and Effects theme is proposed to - among others - be studied by a coordinated approach regarding the Southeast Asian Monsoon, but also by proposals addressing sdimentation, facies evolution and the paleoclimate record in the Atlantic and Indian Oceans. The Solid Earth Cycles and Geodynamics theme is represented by several proposals addressing subduction processes, seismogenesis, and oceanic crust formation mainly in the Pacific. Some of these have shaped drilling programs that are already in the process of being carried out, such as drilling in the Nankai Trough off Japan (the NantroSEIZE project), or drilling in oceanic crust created in a superfast spreading environment in the Eastern Pacific. There are many remaining issues to be addressed, and drilling programs to be completed before the end of the present phase of IODP in 2013. Planning of expeditions needs to be done in such a way that a balance between risk, cost, and scientific impact is achieved. At least part of the dilling also is required to be a necessary precursor for future investigations in coming phases of Ocean Drilling. Presently IODP faces the challenges of tight budgetary constraints, increasing operating costs of their platforms, and the need to develop drilling schedules that allow off-contract work of the R/V Chikyu and R/V Joides Resolution drilling vessels. Chikyu will operate within IODP for an average of 7 months per year over a 5-year period with the goals of achieving major milestones in NantroSEIZE, maximizing the use of the vessel for riser drilling, and start a new IODP project that requires riser drilling. Joides Resolution will also operate an average of 7 months per year with the goal of optimizing operating days within the restrictions imposed by the prioritized science. Mission Specific Platform expeditions will be carried out once every two years on average, with the goal of pioneering drilling in new, challenging environments. For the first time in IODP history, operations of Chikyu, Joides Resolution and Mission Specific Platform expeditions will be conducted simultaneously in 2009. This new phase of operations provides an unprecedented chance of progress in scientific ocean drilling.

The Georges Bank monitoring program 1985; analysis of trace metals in bottom sediments during the third year of monitoring

USGS Publications Warehouse

Bothner, Michael H.; Rendigs, R. R.; Campbell, Esma; Doughten, M.W.; Parmenter, C.M.; O'Dell, C. H.; DiLisio, G.P.; Johnson, R.G.; Gillison, J.R.; Rait, Norma

1986-01-01

Of the 12 elements analyzed in bulk (undifferentiated) sediments collected adjacent to drilling rigs on Georges Bank, only barium was found to increase in concentration during the period when eight exploratory wells were drilled (July 1981 until September 1982). The maximum postdrilling concentration of barium (a major element in drilling mud) reached 172 ppm in bulk sediments near the drill site in block 410. This concentration is higher than the predrilling concentration at this location by a factor of 5.9. This maximum barium concentration is within the range of predrilling concentrations (28-300 ppm) measured in various sediment types from the regional stations of this program. No drilling-related changes in the concentrations of the 11 other metals have been observed in bulk sediments at any of the locations sampled in this program. We estimate that about 25 percent of the barite discharged at block 312 was present in the sediments within 6 km of the rig, 4 weeks after drilling was completed at this location (drilling period was December 8, 1981-June 27, 1982). For almost a year following completion of this well, the inventory of barite decreased rapidly, with a half-life of 0.34 year. During the next year, the inventory decreased at a slower rate (half-life of 3.4 years). The faster rate probably reflects resuspension and sediment transport of bariterich material residing at the sediment surface. Elevated barium concentrations in post-drilling sediment-trap samples from block 312 indicate that such resuspension can occur up to at least 25 m above the sea floor. As the remaining barite particles are reworked deeper into the sediments by currents and bioturbation, removal by sediment-transport processes is slower. The barite discharged during the exploratory phase of drilling is associated with the fine fraction of sediment and is widely distributed around the bank. We found evidence for barium transport to Great South Channel, 115 km west of the drilling, and to stations 2 and 3, 35 km east of the easternmost drilling site. Small increases in barium concentrations, present in the fine fraction of sediment only, were measured also at the heads of both Lydonia and Oceanographer Canyons, located 8 and 39 km, respectively, seaward of the nearest exploratory well.

An Automated, Low Mass, Low Power Drill for Acquiring Subsurface Samples of Ground Ice for Astrobiology Studies on Earth and on Mars

NASA Technical Reports Server (NTRS)

Briggs, G. A.; McKay, C.; George, J.; Derkowski, G.; Cooper, G.; Zacny, K.; Baker, R. Fincher; Pollard, W.; Clifford, S.

2003-01-01

As a project that is part of NASA s Astrobiology Technology & Instrument Development Program (ASTID), we are developing a low mass (approx.20kg) drill that will be operated without drilling fluids and at very low power levels (approx.60 watts electrical) to access and retrieve samples from permafrost regions of Earth and Mars. The drill, designed and built as a joint effort by NASA JSC and Baker-Hughes International, takes the form of a down-hole unit attached to a cable so that it can, in principle, be scaled easily to reach significant depths. A parallel laboratory effort is being carried out at UC Berkeley to characterize the physics of dry drilling under martian conditions of pressure, temperature and atmospheric composition. Data from the UCB and JSC laboratory experiments are being used as input to a drill simulation program which is under development to provide autonomous control of the drill. The first Arctic field test of the unit is planned for May 2004. A field expedition to Eureka on Ellesmere Island in Spring 2003 provided an introduction for several team members to the practical aspects of drilling under Arctic conditions. The field effort was organized by Wayne Pollard of McGill University and Christopher McKay of NASA ARC. A conventional science drill provided by New Zealand colleagues was used to recover ground ice cores for analysis of their microbial content and also to develop techniques using tracers to track the depth of penetration of contamination from the core surface into the interior of the samples.

Texas Hydrogen Education Final Scientific/Technical Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hitchcock, David; Bullock, Dan

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 Statemore » 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 fork lifts, and hydrogen fueling) are effective for engaging target audiences, and (3) a clear path forward is needed for state and local agencies interested in project implementation (funding, financing, preliminary design, technical assistance, etc.).« less

2014-01-01

Purpose Hispanic women in Texas have among the highest rates of cervical cancer incidence and mortality in the country. Increasing regular Papanicolaou test screening and HPV vaccination are crucial to reduce the burden of cervical cancer among Hispanics. This paper presents lessons learned from community-based cervical cancer control programs in Texas and highlights effective intervention programs, methods and strategies. Methods We reviewed and summarized cervical cancer control efforts targeting Hispanic women in Texas, focusing on interventions developed by researchers at the University of Texas, School of Public Health. We identified commonalities across programs, highlighted effective methods, and summarized lessons learned to help guide future intervention efforts. Results Community-academic partnerships were fundamental in all steps of program development and implementation. Programs reviewed addressed psychosocial, cultural, and access barriers to cervical cancer control among low-income Hispanic women. Intervention approaches included lay health worker (LHW) and navigation models and used print media, interactive tailored media, photonovellas, client reminders, one-on-one and group education sessions. Conclusions Small media materials combined with LHW and navigation approaches were effective in delivering Pap test screening and HPV vaccination messages and in linking women to services. Common theoretical methods included in these approaches were modeling, verbal persuasion, and facilitating access. Adaptation of programs to an urban environment revealed that intensive navigation was needed to link women with multiple access barriers to health services. Collectively, this review reveals 1) the importance of using a systematic approach for planning and adapting cervical cancer control programs; 2) advantages of collaborative academic-community partnerships to develop feasible interventions with broad reach; 3) the use of small media and LHW approaches and the need for tailored phone navigation in urban settings; and 4) coordination and technical assistance of community-based efforts as a way to maximize resources.

Smaller Footprint Drilling System for Deep and Hard Rock Environments; Feasibility of Ultra-High-Speed Diamond Drilling

DOE Office of Scientific and Technical Information (OSTI.GOV)

Arnis Judzis; Alan Black; Homer Robertson

2006-03-01

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high rotational speeds (greater than 10,000 rpm). The work includes a feasibility of concept research effort aimed at development that will ultimately result in the ability to reliably drill ''faster and deeper'' possibly with smaller, more mobile rigs. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration (ROP) rock cutting with substantially lower inputs of energymore » and loads. The significance of the ultra-high rotary speed drilling system is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm--usually well below 5,000 rpm. This document details the progress to date on the program entitled ''Smaller Footprint Drilling System for Deep and Hard Rock Environments: Feasibility of Ultra-High-Speed Diamond Drilling'' for the period starting 1 October 2004 through 30 September 2005. Additionally, research activity from 1 October 2005 through 28 February 2006 is included in this report: (1) TerraTek reviewed applicable literature and documentation and convened a project kick-off meeting with Industry Advisors in attendance. (2) TerraTek designed and planned Phase I bench scale experiments. Some difficulties continue in obtaining ultra-high speed motors. Improvements have been made to the loading mechanism and the rotational speed monitoring instrumentation. New drill bit designs have been provided to vendors for production. A more consistent product is required to minimize the differences in bit performance. A test matrix for the final core bit testing program has been completed. (3) TerraTek is progressing through Task 3 ''Small-scale cutting performance tests''. (4) Significant testing has been performed on nine different rocks. (5) Bit balling has been observed on some rock and seems to be more pronounces at higher rotational speeds. (6) Preliminary analysis of data has been completed and indicates that decreased specific energy is required as the rotational speed increases (Task 4). This data analysis has been used to direct the efforts of the final testing for Phase I (Task 5). (7) Technology transfer (Task 6) has begun with technical presentations to the industry (see Judzis).« less

The TXESS Revolution: A Partnership to Advance Earth and Space Science in Texas

NASA Astrophysics Data System (ADS)

Ellins, K. K.; Olson, H. C.; Willis, M.

2007-12-01

The Texas State Board of Education voted in 2006 to require a fourth year of science for graduation from high school and to authorize the creation of a new senior level Earth Systems and Space Science course as an option to fulfill that requirement. The new Earth Systems and Space Science course will be a capstone course for which three required science courses(biology, chemistry and physics)are prerequisites. Here, we summarize the collective efforts of business leaders, scientists and educators who worked collaboratively for almost a decade to successfully reinstate Earth science as part of Texas' standard high school curriculum and describe a new project, the Texas Earth and Space Science (TXESS) Revolution, a 5-year professional development program for 8th -12th grade minority and minority-serving science teachers and teacher mentors in Texas to help prepare them to teach the new capstone course. At the heart of TXESS Revolution is an extraordinary partnership, involving (1) two UT-Austin academic units, the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering; (2) TERC, a not-for-profit educational enterprise in Massachusetts with 30 years experience in designing science curriculum; (3) the University of South Florida; and (4) the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching, a statewide network of teacher mentors and science teachers. With guidance from the Texas Education Agency, the state agency charged with overseeing education, the TXESS Revolution project will provide teachers with access to high quality materials and instruction aligned with the Texas educational standards for the new capstone course through: a program of eight different 3-day professional development academies offered to both teachers and teachers mentors; immersive summer institutes, field experiences, and a Petroleum Science and Technology Institute; training on how to implement Earth Science by Design, a teacher professional development program developed by TERC and the American Geological Institute with National Science Foundation (NSF) funding; and an online learning forum designed to keep teachers and teacher mentors in contact with facilitators and fellow project-participants between and after training, as well as share best practices and new information. The new capstone course promises to be a rigorous and dynamic change to the way Earth and Space Science has been presented previously anywhere in the U.S. and will provide many opportunities for professional development and the dissemination of suitable Earth and Space Science curriculum. The TXESS Revolution project welcomes opportunities to collaborate with geoscience consortia, programs, organizations and geoscience educators to advance Earth and Space Science in Texas. NSF's Opportunities to Enhance Diversity in the Geosciences program, the Shell Oil Company and the Jackson School of Geosciences are together funding the TXESS Revolution project.

Floods on small streams in Texas

USGS Publications Warehouse

Ruggles, Frederick H.

1966-01-01

The first streamflow station in Texas was established on the Rio Grande at El Paso on May 10, 1889. Sip,ce that time the systematic collection of streamflow data. has expanded. In 1915 the Texas Board of Water Engineers (now the Texas Water Development Board) entered into a cooperative agreement with the U. S. Geological Survey for the purpose of expanding the network of stream-gaging stations in Texas. Sites were selected for stream-gaging stations to obtain hydrologic data for water supply and flood control. Therefore, the stream-gaging stations were located principally on major streams. Today, after three-quarters of a century.of hydrologic data collection, peak discharge data on small streams are still deficient in Texas. The Geological Survey and the Texas Highway Department, therefore, have entered into a cooperative program to collect peak discharge data on small streams for the purpose of deriving flood-frequency data needed for the economical design of culverts and small bridges.

Comparative Analysis of Cutting Efficiency and Surface Maintenance Between Different Types of Implant Drills: An In Vitro Study.

This study evaluated cutting efficiency (CE) and linear wear of dental implant drills after 450 standardized osteotomies on bovine ribs. Diamond-like carbon-coated steel drills (SG), acid-treated steel drills (EG), and ceramic drills (ZG) were divided into 6 subgroups according to the number of uses. A robot-controlled program performed systematic instrumentation, timing, axial loading, and managed feed rate. CE was recorded in a polyurethane resin blank and end wear (VBBmax) was analyzed under stereo microscopy. After osteotomies in beef ribs, CE for the Ø2.0-mm drill decreased 10.2% in SG and 10.9% in ZG; for the Ø3.0-mm drill, CE decreased 30.6% in SG, 8.5% in ZG, and improved in EG. The greatest wear occurred in Ø2.0-mm drills; ZG drills (Ø3.0 mm) exhibited only edge frittering, as confirmed on scanning electron microscopy. After 50 exposures to mechanical loads, steel and ceramic drills lost CE. Whereas cutting and thermal performance improved in experimental drills, the Ø2.0-mm drill exhibited the most signs of wear proportional to use. These findings suggest that, with the methodology employed, the life of these drills exceeds 50 osteotomies.

After a lengthy battle with the Texas A&M University Radiation Safety Office, the Texas Department of State Health Services granted us a license for the production of radionuclides in July 2015, allowing us to work in earnest in our project objectives. Experiments began immediately after licensing, and we started the assembly and testing of our target systems. There were four analytical/theoreticalmore » projects and two experimental target systems. These were for At-211 production and for Zn- 62/Cu-62 production. The theoretical projects were related to the production of Mo-99/Tc-99m using (a) a subcritical aqueous target system and (b) production of Tc-99m from accelerator-generated Mo-99 utilizing a photon-neutron interaction with enriched Mo-100 targets. The two experimental projects were the development of targetry systems and production of At-211 and Zn-62/Cu-62 generator. The targetry system for At-211 has been tested and production of At-211 is chronic depending of availability of beam time at the cyclotron. The installation and testing of the targetry system for the production of Zn-62/Cu-62 has not been finalized. A description of the systems is described. The academic program in radionuclide production and separation methods was initiated in the fall of 2011; due to the lack of a radiochemistry laboratory, it was suspended.

Losing and Saving and Losing Physics in Texas

NASA Astrophysics Data System (ADS)

Marder, Michael

2015-03-01

Texas has the second-largest population of the states, and played even a larger role in education reform movements of the past 15 years than its size would indicate. In the Fall of 2011, physicists across the country were surprised to learn that six university physics programs in Texas were threatened with closure because of small graduation numbers. Five of them ultimately closed. Many of the faculty at the institutions losing programs came together and formed a consortium that eventually made it possible to continue offering physics,by unconventional means, to their undergraduates. In the Spring of 2013 came an even larger change. Physics had been part of the recommended high school graduation plan in Texas. As part of a bill making sweeping changes to high school graduation requirements and accountability, the physics requirement was removed. Physics may partly be falling victim to the national focus on STEM, which suggests that the various disciplines of science are interchangeable and not individually important. None of the changes in Texas are hard to imagine coming to other states as well.

Evaluation of commercial utility of ERTS-A imagery in structural reconnaissance for minerals and petroleum

NASA Technical Reports Server (NTRS)

Saunders, D. F.; Thomas, G. E.

1973-01-01

Five areas in North America (North Slope-Alaska, Superior Province-Canada, Williston Basin-Montana, Colorado and New Mexico-West Texas) are being studied for discernibility of geological evidence on ERTS-1 imagery, Evidence mapped is compared with known mineral/hydrocarbon accumulations to determine the value of the imagery in commercial exploration programs. Evaluation has proceeded in the New Mexico-West Texas area while awaiting imagery in the other areas. To date, results have been better than expected. Clearly discernible structural lineaments in New Mexico-West Texas are evident on the photographs. Comparison of this evidence with known major mining localities in New Mexico indicates a clear pattern of coincidence between the lineaments and mining localities. In West Texas, lineament and geomorphological evidence obtainable from the photographs define the petroleum-productive Central Basin Platform. Based on evaluation results in the New Mexico-West Texas area and on cursory results in the other four areas of North America, ERTS-1 imagery will be extremely valuable in defining the regional and local structure in any commercial exploration program.

Scientific Drilling of Impact Craters - Well Logging and Core Analyses Using Magnetic Methods (Invited)

NASA Astrophysics Data System (ADS)

Fucugauchi, J. U.; Perez-Cruz, L. L.; Velasco-Villarreal, M.

2013-12-01

Drilling projects of impact structures provide data on the structure and stratigraphy of target, impact and post-impact lithologies, providing insight on the impact dynamics and cratering. Studies have successfully included magnetic well logging and analyses in core and cuttings, directed to characterize the subsurface stratigraphy and structure at depth. There are 170-180 impact craters documented in the terrestrial record, which is a small proportion compared to expectations derived from what is observed on the Moon, Mars and other bodies of the solar system. Knowledge of the internal 3-D deep structure of craters, critical for understanding impacts and crater formation, can best be studied by geophysics and drilling. On Earth, few craters have yet been investigated by drilling. Craters have been drilled as part of industry surveys and/or academic projects, including notably Chicxulub, Sudbury, Ries, Vredefort, Manson and many other craters. As part of the Continental ICDP program, drilling projects have been conducted on the Chicxulub, Bosumtwi, Chesapeake, Ries and El gygytgyn craters. Inclusion of continuous core recovery expanded the range of paleomagnetic and rock magnetic applications, with direct core laboratory measurements, which are part of the tools available in the ocean and continental drilling programs. Drilling studies are here briefly reviewed, with emphasis on the Chicxulub crater formed by an asteroid impact 66 Ma ago at the Cretaceous/Paleogene boundary. Chicxulub crater has no surface expression, covered by a kilometer of Cenozoic sediments, thus making drilling an essential tool. As part of our studies we have drilled eleven wells with continuous core recovery. Magnetic susceptibility logging, magnetostratigraphic, rock magnetic and fabric studies have been carried out and results used for lateral correlation, dating, formation evaluation, azimuthal core orientation and physical property contrasts. Contributions of magnetic studies on impact age, cratering, target-impactite stratigraphy, ejecta, impact dynamics, hydrothermal alterations and post-impact processes are presented. The challenges and perspectives of drilling studies of impact craters are discussed.

Paleomagnetic and Magnetostratigraphic Studies in Drilling Projects of Impact Craters - Recent Studies, Challenges and Perspectives

Paleomagnetic studies have long been successfully carried out in drilling projects, to characterize the borehole columns and to investigate the subsurface structure and stratigraphy. Magnetic susceptibility logging and magnetostratigraphic studies provide data for lateral correlation, formation evaluation, azimuthal core orientation, physical properties, etc., and are part of the tools available in the ocean and continental drilling programs. The inclusion of continuous core recovery in scientific drilling projects have greatly expanded the range of potential applications of paleomagnetic and rock magnetic studies, by allowing laboratory measurements on core samples. For this presentation, we concentrate on drilling studies of impact structures and their usefulness for documenting the structure, stratigraphy and physical properties at depth. There are about 170-180 impact craters documented in the terrestrial record, which is a small number compared to what is observed in the Moon, Mars, Venus and other bodies of the solar system. Of the terrestrial impact craters, only a few have been studied by drilling. Some craters have been drilled as part of industry exploration surveys and/or academic projects, including notably the Sudbury, Ries, Vredefort, Manson and many other craters. As part of the Continental ICDP program, drilling projects have been conducted on the Chicxulub, Bosumtwi, Chesapeake and El gygytgyn craters. Drilling of terrestrial craters has proved important in documenting the shallow stratigraphy and structure, providing insight on the cratering and impact dynamics. Questions include several that can only be addressed by retrieving core samples and laboratory analyses. Paleomagnetic, rock magnetic and fabric studies have been conducted in the various craters, which are here summarized with emphasis on the Chicxulub crater and Yucatan carbonate platform. Chicxulub is buried under a kilometer of younger sediments, making drilling an essential tool. Oil exploration included several boreholes, and additionally we have drilled 11 boreholes with continuous core recovery. Contributions and limitations of paleomagnetism for investigating the impact age, crater stratigraphy, cratering, ejecta emplacement, impact dynamics, hydrothermal system and post-impact processes are discussed.

Application of drilling, coring, and sampling techniques to test holes and wells

USGS Publications Warehouse

Shuter, Eugene; Teasdale, Warren E.

1989-01-01

The purpose of this manual is to provide ground-water hydrologists with a working knowledge of the techniques of test drilling, auger drilling, coring and sampling, and the related drilling and sampling equipment. For the most part, the techniques discussed deal with drilling, sampling, and completion of test holes in unconsolidated sediments because a hydrologist is interested primarily in shallow-aquifer data in this type of lithology. Successful drilling and coring of these materials usually is difficult, and published research information on the subject is not readily available. The authors emphasize in-situ sampling of unconsolidated sediments to obtain virtually undisturbed samples. Particular attention is given to auger drilling and hydraulic-rotary methods of drilling because these are the principal means of test drilling performed by the U.S. Geological Survey during hydrologic studies. Techniques for sampling areas contaminated by solid or liquid waste are discussed. Basic concepts of well development and a detailed discussion of drilling muds, as related to hole conditioning, also are included in the report. The information contained in this manual is intended to help ground-water hydrologists obtain useful subsurface data and samples from their drilling programs.

Comparison of early exploration at Platanares (Honduras) and Wairakei (New Zealand)

1989-01-01

Early exploration at Wairakei, New Zealand, is compared with the present state of exploration of Platanares, Honduras. In retrospect, geothermometer temperatures favor Platanares (e.g., 220 vs. 190??C for Na-K-Ca), but two 600-m drill holes encountered lower temperatures (160??C). Wairakei, explored before the advent of chemical geothermometry, also had disappointing early drilling results (but better than Platanares; one of the first six holes hit T > 180??C). The Wairakei drilling program was nevertheless continued at full speed and by well 20 a successful drilling strategy was discovered.

Natural gas hydrates are of interest as a future hydrocarbon source, however, the formation and physical properties of such systems are not fully understood. In May 2017, the University of Texas drilled two holes in Green Canyon Block 955, northern Gulf of Mexico to collect pressurized core from a thick, 100 m accumulation of gas hydrate in a silt dominated submarine canyon levee system. The expedition, known as UT-GOM2-01, collected 21, 10-m pressure cores from Holes H002 and H005. Approximately half of the cores successfully pressurized and were fully recovered. Unsuccessful cores that did not pressurize generally had low core recovery. By analyzing the sediment composition in known gas hydrate reservoirs, we can construct a more detailed picture of how and why gas hydrates accumulate, as mineralogy can affect physical properties such as porosity and permeability as well as geophysical measurements such as resistivity. Using X-ray diffraction (XRD) on bulk sediment powders, we determined the bulk mineralogy of the samples. Moreover, we investigated drilling mud contamination using XRD and light optical analysis. In some cores, contamination was easily recognized visually as dense sludge between the core barrel and the recovered sediment core, however drilling mud is best observed both along the liner and interbedded within the sediment on X-ray computed tomography scans. To fully identify the presence and influence of drilling mud, we use XRD to analyze samples on cores collected both while drilling mud was used in hole and when only seawater was used in hole and consider the density anomalies observed on the XCT scans. The preliminary XRD light optical microscopy results show that the silt-dominated reservoir is primarily composed of quartz, with minor alkali feldspar, amphibole, muscovite, dolomite, and calcite. Samples from intervals with suspected drilling mud contamination show a similar composition, but with the addition of barite, a common component in drilling mud. Understanding why contamination occurs will improve the coring process and ensure maximum recovery in the future. The XRD data also show the presence of 7-angstrom clay minerals, most likely chlorite and serpentine, but more analysis is required in order to verify the identification and to establish relative abundances of each mineral.

The Swedish Deep Drilling Program (SDDP) Collisional Orogeny in the Scandinavian Caledonides (COSC) project is a multidisciplinary investigation of the Scandian mountain belt. Cenozoic uplift of the Scandes has exposed a lower- to middle-crustal level section through this Himalaya-type orogen, providing unique opportunities to better understand not only the Caledonides, but also on-going orogeny and the earthquake-prone environments of modern mountains belts. COSC will also contribute to our knowledge of mountain belt hydrology, provide the first information about deep thermal gradients for paleoclimate modeling and potential geothermal energy resources, contribute new information about the deep biosphere, and improve our understanding of the Cenozoic uplift history of the Scandes. The drilling program targets the far-traveled (> 400 km) allochthons of the Scandinavian Caledonides and their emplacement across the Baltoscandian foreland basin onto the platform of continent Baltica. Two 2.5 km deep holes are planned. COSC-1, to be drilled in the summer of 2013, will target the high-grade metamorphic complex of the Seve Nappes (SNC) and its contact to underlying allochthons. COSC-2 will start in the lower thrust sheets, pass through the basal décollement and investigate the character of the deformation in the underlying basement. An international science team, including expertise on Himalaya-Tibet and other young orogens, is running the science program. New high-resolution reflection seismic data provide excellent images of the upper crust. Alternative interpretations of the reflectors' origin, particularly those in the basement, will be tested. The site of COSC-1 is based on a 3D geological model, constructed from surface geology, recent and vintage regional reflection seismic profiles, regional and local gravity data, and high-resolution aeromagnetics, acquired recently by the Geological Survey of Sweden. The drilling will be carried out utilising the new Swedish scientific drilling infrastructure, located at Lund University, an Atlas Copco CT20 diamond core-drilling rig, with versatile drilling equipment (see EGU2012-7379), providing the ideal platform for core-drilling to 2.5 km depths. Existing drilling, sampling and testing techniques (e.g. triple-tube core drilling for best core quality) will need to be adapted to highly variable lithologies and new techniques will be developed, as necessary. COSC-1 drilling operations and the directly related on-site investigations are financed by ICDP and the Swedish Research Council. All drill cores will be transferred to the core repository of the Geological Survey of Sweden, and a sampling party will be announced later this year. Researchers who want to participate in COSC and contribute their expertise are encouraged to inform us of their interests.

ELF Aquitaine used horizontal drilling during a pilot test program to bring commercial production from its Rospo Mare oil discovery in the Adriatic, which would have been a costly disappointment if drilled by a conventional vertical well bore. Rospo Mare is a large reservoir containing a top column of highly viscous crude underlain by a water column. The company felt that a well bore that penetrated the reservoir vertically would bring early flooding of the oil column and yield only water. By penetrating the reservoir with a horizontal well drilled high in the oil column, the well successfully produced onmore » numerous tests from Oct. 1982 until the end of the test program in 1983. Production was termed excellent, with productivity during tests reportedly reaching ca 15 times the rate produced from nearby vertical wells. However, ELF said the results usually average ca 5 times the usual rate of vertical wells.« less

The Auto-Gopher Deep Drill

NASA Technical Reports Server (NTRS)

Badescu, Mircea

2014-01-01

Subsurface penetration by coring, drilling or abrading is of great importance for a large number of space and earth applications. An Ultrasonic/Sonic Drill/Corer (USDC) has been in development at JPL's Nondestructive Evaluation and Advanced Actuators (NDEAA) lab as an adaptable tool for many of these applications. The USDC uses a novel drive mechanism to transform the high frequency ultrasonic or sonic vibrations of the tip of a horn into a lower frequency sonic hammering of a drill bit through an intermediate free-flying mass. The USDC device idea has been implemented at various scales from handheld drills to large diameter coring devices. A series of computer programs that model the function and performance of the USDC device were developed and were later integrated into an automated modeling package. The USDC has also evolved from a purely hammering drill to a rotary hammer drill as the design requirements increased form small diameter shallow drilling to large diameter deep coring. A synthesis of the Auto-Gopher development is presented in this paper.

On July 16, 1953, a diamond core-drilling program was begun in the pumpkin Buttes area to secure geologic information. Drilling was terminated March 11, 1964, after 12 holes had been completed for a total of 5,813 feet. An investigational rotary noncore-drilling project was conducted from June l4, to September 17, 1954, in the southern part of the Powder River Basin, Campbell, Johnson, and Converse Counties, Wyoming. Drilling was done in the Pumpkin Buttes area and the Converse County area. A total of 52,267 feet was drilled and the average depth of hole was 75.3 feet. Forty-one anomalous areas in themore » Powder River Basin were drilled; of these, three in Converse County were found to contain possible commercial ore bodies.

1983-03-01

The powerful Rosenbrock search technique, which optimizes both the search directions using the Gram-Schmidt procedure and the step size using the Fibonacci line search method, has been used to optimize the drilling program of an oil well drilled in Bai-Hassan oil field in Kirkuk, Iran, using the twodimensional drilling model of Galle and Woods. This model shows the effect of the two major controllable variables, weight on bit and rotary speed, on the drilling rate, while considering other controllable variables such as the mud properties, hydrostatic pressure, hydraulic design, and bit selection. The effect of tooth dullness on the drillingmore » rate is also considered. Increasing the weight on the drill bit with a small increase or decrease in ratary speed resulted in a significant decrease in the drilling cost for most bit runs. It was found that a 48% reduction in this cost and a 97-hour savings in the total drilling time was possible under certain conditions.« less

HOLEGAGE 1.0 - STRAIN GAGE HOLE DRILLING ANALYSIS PROGRAM

NASA Technical Reports Server (NTRS)

Hampton, R. W.

1994-01-01

There is no simple and perfect way to measure residual stresses in metal parts that have been welded or deformed to make complex structures such as pressure vessels and aircraft, yet these locked-in stresses can contribute to structural failure by fatigue and fracture. However, one proven and tested technique for determining the internal stress of a metal part is to drill a test hole while measuring the relieved strains around the hole, such as the hole-drilling strain gage method described in ASTM E 837. The program HOLEGAGE processes strain gage data and provides additional calculations of internal stress variations that are not obtained with standard E 837 analysis methods. The typical application of the technique uses a three gage rosette with a special hole-drilling fixture for drilling a hole through the center of the rosette to produce a hole with very small gage pattern eccentricity error. Another device is used to control the drilling and halt the drill at controlled depth steps. At each step, strains from all three strain gages are recorded. The influence coefficients used by HOLEGAGE to compute stresses from relieved hole strains were developed by published finite element method studies of thick plates for specific hole sizes and depths. The program uses a parabolic fit and an interpolating scheme to project the coefficients to other hole sizes and depths. Additionally, published experimental data are used to extend the coefficients to relatively thin plates. These influence coefficients are used to compute the stresses in the original part from the strain data. HOLEGAGE will compute interior planar stresses using strain data from each drilled hole depth layer. Planar stresses may be computed in three ways including: a least squares fit for a linear variation with depth, an integral method to give incremental stress data for each layer, or by a linear fit to the integral data (with some surface data points omitted) to predict surface stresses before strain gage sanding preparations introduced additional residual stresses. Options are included for estimating the effect of hole eccentricity on calculations, smoothing noise from the strain data, and inputting the program data either interactively or from a data file. HOLEGAGE was written in FORTRAN 77 for DEC VAX computers under VMS, and is transportable except for system-unique TIME and DATE system calls. The program requires 54K of main memory and was developed in 1990. The program is available on a 9-track 1600 BPI VAX BACKUP format magnetic tape (standard media) or a TK50 tape cartridge. The documentation is included on the tape. DEC VAX and VMS are trademarks of Digital Equipment Corporation.

Concept Study: Exploration and Production in Environmentally Sensitive Arctic Areas

DOE Office of Scientific and Technical Information (OSTI.GOV)

2008-12-31

The Alaska North Slope offers one of the best prospects for increasing U.S. domestic oil and gas production. However, this region faces some of the greatest environmental and logistical challenges to oil and gas production in the world. A number of studies have shown that weather patterns in this region are warming, and the number of days the tundra surface is adequately frozen for tundra travel each year has declined. Operators are not allowed to explore in undeveloped areas until the tundra is sufficiently frozen and adequate snow cover is present. Spring breakup then forces rapid evacuation of the areamore » prior to snowmelt. Using the best available methods, exploration in remote arctic areas can take up to three years to identify a commercial discovery, and then years to build the infrastructure to develop and produce. This makes new exploration costly. It also increases the costs of maintaining field infrastructure, pipeline inspections, and environmental restoration efforts. New technologies are needed, or oil and gas resources may never be developed outside limited exploration stepouts from existing infrastructure. Industry has identified certain low-impact technologies suitable for operations, and has made improvements to reduce the footprint and impact on the environment. Additional improvements are needed for exploration and economic field development and end-of-field restoration. One operator-Anadarko Petroleum Corporation-built a prototype platform for drilling wells in the Arctic that is elevated, modular, and mobile. The system was tested while drilling one of the first hydrate exploration wells in Alaska during 2003-2004. This technology was identified as a potentially enabling technology by the ongoing Joint Industry Program (JIP) Environmentally Friendly Drilling (EFD) program. The EFD is headed by Texas A&M University and the Houston Advanced Research Center (HARC), and is co-funded by the National Energy Technology Laboratory (NETL). The EFD participants believe that the platform concept could have far-reaching applications in the Arctic as a drilling and production platform, as originally intended, and as a possible staging area. The overall objective of this project was to document various potential applications, locations, and conceptual designs for the inland platform serving oil and gas operations on the Alaska North Slope. The University of Alaska Fairbanks assisted the HARC/TerraPlatforms team with the characterization of potential resource areas, geotechnical conditions associated with continuous permafrost terrain, and the potential end-user evaluation process. The team discussed the various potential applications with industry, governmental agencies, and environmental organizations. The benefits and concerns associated with industry's use of the technology were identified. In this discussion process, meetings were held with five operating companies (22 people), including asset team leaders, drilling managers, HSE managers, and production and completion managers. Three other operating companies and two service companies were contacted by phone to discuss the project. A questionnaire was distributed and responses were provided, which will be included in the report. Meetings were also held with State of Alaska Department of Natural Resources officials and U.S. Bureau of Land Management regulators. The companies met with included ConcoPhillips, Chevron, Pioneer Natural Resources, Fairweather E&P, BP America, and the Alaska Oil and Gas Association.« less

Engineering report on drilling in the San Rafael Swell area, Utah

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jones, L.I.

1980-05-01

The San Rafael Swell drilling project was conducted by Bendix Field Engineering Corporation in support of the US Department of Energy National Uranium Resource Evaluation (NURE) program. This project consisted of 27 drill holes ranging in depth from 120.0 ft (36.5 m) to 3,700.0 ft (1,127.7 m). A total of 41,716 ft (12,715 m) was drilled, of which 3,099.8 ft (944.8 m) were cored. Geophysical logging was supplied by Century Geophysical Corporation and Bendix Field Engineering Corporation. The objective of the project was to test the uranium potential of the Triassic and Jurassic sandstone units and to investigate areas wheremore » industry was unlikely to drill in the near future. Drilling commenced September 24, 1978, and was finished on December 17, 1979.« less

New scientific ocean drilling depth record extends study of subseafloor life

NASA Astrophysics Data System (ADS)

Showstack, Randy

2012-09-01

The Japanese deep-sea drilling vessel Chikyu set a new depth record for scientific ocean drilling and core retrieval by reaching a depth of 2119.5 meters below the seafloor (mbsf) on 6 September. This is 8.5 meters deeper than the prior record, set 19 years ago. Three days later, on 9 September, Chikyu set another record by reaching a drilling depth of 2466 mbsf, the maximum depth that will be attempted during the current expedition. The 6 September record was set on day 44 of the Deep Coalbed Biosphere off Shimokita expedition, which is expedition 337 of the Integrated Ocean Drilling Program (IODP). It occurred at drilling site C0020 in the northwestern Pacific Ocean, approximately 80 kilometers northeast from Hachinohe, Japan. The expedition is scheduled to conclude on 30 September.

2011 Astronomy Day at McDonald Observatory

NASA Astrophysics Data System (ADS)

Preston, Sandra; Hemeway, M.; Wetzel, M.

2012-01-01

Our philosophy is that everyday is Astronomy Day because the McDonald Observatory's Frank N. Bash Visitors Center is open 362 days a year. So, how did we create a special celebration for the "Astronomy Day” declared by the Astronomical League? During September 26-29 we conducted 20 videoconferences and served 12,559 students with "Astronomy Day” programming. Connect2Texas provides bridging for a network of Texas-based museums and cultural, historical, and scientific organizations that offer educational content to schools throughout the state via videoconferencing. Connect2Texas connected McDonald Observatory to 334 schools; most of these schools were in Texas, but schools in a dozen other states also participated. While most schools had a "view-only" connection, at least 20 of the schools had interactive connections, whereby the students could ask questions of the presenter. Connect2Texas also collects evaluation information from the participating schools that we will use to produce a report for our funders and make modifications to future programs as need be. The videoconferences were offered free of charge. The theme for the 2011 Astronomy Day program was the Year of the Solar System, which aligns with NASA's theme for 2011 and 2012. By aligning with this NASA theme, we could leverage NASA artwork and materials to both advertise and enrich the learning experience. Videoconference materials also included pre- and post-videoconference assessment sheets, an inquiry based activity, and pre- and post-videoconference activities, all of which were made available online. One of the lessons learned from past Astronomy Day videoconferences is that the days the Astronomical League declares as "Astronomy Day” are not always good days for Texas schools to participate. So, we choose an Astronomy Day that meets the needs of Texas schools and our schedule - so any day can be Astronomy Day. 2011 Astronomy Day was made possible by The Meyer-Levy Charitable Trust.

Hawaii Scientific Drilling Project: Objectives, Successes, Surprises and Frustrations

Depaolo, D. J.; Stolper, E.; Thomas, D. M.

2008-12-01

The Hawaii Scientific Drilling Project (HSDP) is a long-running project undertaken with the objective of studying a mantle plume by drilling an extended sequence of lavas from a single Hawaiian volcano. The project originated with a proposal to NSF in late 1986 with the idea of drilling to the Moho under Hilo; the target depth was estimated at 12km, commensurate with the depth reached by the drilling program then being pursued by the USSR and that proposed in the U.S. for the southern Appalachians, and in line with the aspirations of the nascent DOSECC program. Subsequently, due to limitations in funding and reorganization of the drilling program into what later became the NSF Continental Dynamics Program, HSDP was re-scoped with the objective of drilling deeply enough (ca. 4.5km) to recover most of the eruptive history of a single volcano. The project first went to a pilot stage, which resulted in coring to a depth of 1.1km in late 1993. The pilot stage was relatively inexpensive (1M including science) and productive. Funding was then obtained from NSF and ICDP in 1995 (ca. 12M) with the objective of drilling to 4.5km. Drilling was originally planned for a five-year period, in two campaigns. The first campaign, in 1999, resulted in efficient coring to a depth of 3.1km over a period of 6 months; it used about 40 percent of the funds and was also highly productive. Deepening the hole below 3.1km turned out to be both difficult and expensive, although for interesting reasons. To facilitate deeper drilling the hole needed to be reamed to a larger diameter; but when this was done the well unexpectedly started to flow. We now know that there are several deep pressurized aquifers, with varying salt content, but these hydrological phenomena were totally unanticipated. A key finding, also unanticipated, is that cold seawater circulates through the volcanic pile in volumes sufficient to refrigerate the entire section below 700m depth to temperatures about 25 degrees below a normal geothermal gradient. In early 1999 when the first drilling campaign was organized, the price of oil was 10 USD (rigs and drilling crews were available and reasonably priced); in early 2003 when hole opening was being arranged, the price of oil was 30 USD, and for the coring campaigns in 2005 and 2007 it was 50 to 70 USD. For these reasons, and because trip times were longer and deeply buried pillow basalts more difficult to drill, the remainder of the project funds (and then some) were needed to deepen the hole from 3.1 to 3.5km. Nevertheless, the project obtained a nearly continuous, and virtually unweathered, core consisting of lava flows, hyaloclastite, minor intrusives and sediment from a 3260m section of the Mauna Kea volcano, covering an age range from 200 to over 600 ka. It also recovered a 250m and a 280m section of the Mauna Loa volcano. A wealth of geological, volcanological, petrological, geochemical, geomagnetic, geodynamic, hydrological, and geobiological data have come from the core and the well, and more are coming in. The unprecedented geochemical-petrological data sets are a major success, as is the fact that geochemists can work together, but the hoped-for detailed geochronology for the core has proven difficult to obtain.

High Resolution Vertical Seismic Profile from the Chicxulub IODP/ICDP Expedition 364 Borehole: Wave Speeds and Seismic Reflectivity.

We acquired a closely-spaced vertical seismic profile (VSP) in the Chicxulub K-Pg Impact Crater drilling program borehole to calibrate the existing surface seismic profiles and provide complementary measurements of in situ seismic wave speeds. Downhole seismic records were obtained at spacings ranging from 1.25 m to 5 m along the borehole from 47.5 m to 1325 mwsf (meters wireline below sea floor) (Fig 1a) using a Sercel SlimwaveTM geophone chain (University of Alberta). The seismic source was a 30/30ci Sercel Mini GI airgun (University of Texas), fired a minimum of 5 times per station. Seismic data processing used a combination of a commercial processing package (Schlumberger's VISTA) and MatlabTM codes. The VSP displays detailed reflectivity (Fig. 1a) with the strongest reflection seen at 600 mwsf (280 ms one-way time), geologically corresponding to the sharp contact between the post-impact sediments and the target peak ring rock, thus confirming the pre-drilling interpretations of the seismic profiles. A two-way time trace extracted from the separated up-going wavefield matches the major reflection both in travel time and character. In the granitic rocks that form the peak ring of the Chicxulub impact crater, we observe P-wave velocities of 4000-4500 m/s which are significantly less than the expected values of granitoids ( 6000 m/s) (Fig. 1b). The VSP measured wave speeds are confirmed against downhole sonic logging and in laboratory velocimetry measurements; these data provide additional evidence that the crustal material displaced by the impact experienced a significant amount of damage. Samples and data provided by IODP. Samples can be requested at http://web.iodp.tamu.edu/sdrm after 19 October 2017. Expedition 364 was jointly funded by ECORD, ICDP, and IODP with contributions and logistical support from the Yucatan State Government and UNAM. The downhole seismic chain and wireline system is funded by grants to DRS from the Canada Foundation for Innovation and the Alberta Enterprise and Advanced Education Grants Program.

2006-03-01

Operators continue to look for ways to improve hard rock drilling performance through emerging technologies. A consortium of Department of Energy, operator and industry participants put together an effort to test and optimize mud driven fluid hammers as one emerging technology that has shown promise to increase penetration rates in hard rock. The thrust of this program has been to test and record the performance of fluid hammers in full scale test conditions including, hard formations at simulated depth, high density/high solids drilling muds, and realistic fluid power levels. This paper details the testing and results of testing two 7more » 3/4 inch diameter mud hammers with 8 1/2 inch hammer bits. A Novatek MHN5 and an SDS Digger FH185 mud hammer were tested with several bit types, with performance being compared to a conventional (IADC Code 537) tricone bit. These tools functionally operated in all of the simulated downhole environments. The performance was in the range of the baseline ticone or better at lower borehole pressures, but at higher borehole pressures the performance was in the lower range or below that of the baseline tricone bit. A new drilling mode was observed, while operating the MHN5 mud hammer. This mode was noticed as the weight on bit (WOB) was in transition from low to high applied load. During this new ''transition drilling mode'', performance was substantially improved and in some cases outperformed the tricone bit. Improvements were noted for the SDS tool while drilling with a more aggressive bit design. Future work includes the optimization of these or the next generation tools for operating in higher density and higher borehole pressure conditions and improving bit design and technology based on the knowledge gained from this test program.« less

In 2003, Texas initiated an experiment to address enrollment disparities in its medical schools. With bipartisan support from key Texas legislators, funding was allocated in 2002 to establish the Joint Admission Medical Program (JAMP). Texas' then eight medical schools created, through JAMP, a partnership with the state's 31 public and 34 private undergraduate colleges and universities. Cognizant of legal prohibitions against reliance solely on race or ethnicity in promoting diversity, JAMP is designed to enhance opportunities for economically disadvantaged students from across the state, including those from (1) rural and remote areas of the state, and (2) institutions that have historically sent few students to medical school. Now in its seventh year of operation, JAMP is overseen by a council with representatives from all nine Texas medical schools. For the six years-2003 to 2008-for which data are available, indicators of JAMP performance can be seen in (1) the numbers of applicants to JAMP (1,230 applicants in the first six years), (2) levels of JAMP participation (480 participants), and (3) matriculation of JAMP participants into medical schools (164 of 288 of those accepted into the program in the years 2003-2006).The authors provide a brief history of JAMP, describe its structure and operation, summarize objective performance data, and identify some of the challenges still faced. These include increasing the participation of students from underrepresented minority groups within the legal structure for the program, and fostering substantive participation in JAMP by all of Texas' undergraduate institutions. A focused effort is under way to strengthen the evaluative aspects of JAMP so that more comprehensive data, including subjective evaluation data from participants, can be shared with colleagues in the future.

Foot drill is a key component of military training and is characterized by frequent heel stamping, likely resulting in high tibial shock magnitudes. Higher tibial shock during running has previously been associated with risk of lower limb stress fractures, which are prevalent among military populations. Quantification of tibial shock during drill training is, therefore, warranted. This study aimed to provide estimates of tibial shock during military drill in British Army Basic training. The study also aimed to compare values between men and women, and to identify any differences between the first and final sessions of training. Tibial accelerometers were secured on the right medial, distal shank of 10 British Army recruits (n = 5 men; n = 5 women) throughout a scheduled drill training session in week 1 and week 12 of basic military training. Peak positive accelerations, the average magnitude above given thresholds, and the rate at which each threshold was exceeded were quantified. Mean (SD) peak positive acceleration was 20.8 (2.2) g across all sessions, which is considerably higher than values typically observed during high impact physical activity. Magnitudes of tibial shock were higher in men than women, and higher in week 12 compared with week 1 of training. This study provides the first estimates of tibial shock magnitude during military drill training in the field. The high values suggest that military drill is a demanding activity and this should be considered when developing and evaluating military training programs. Further exploration is required to understand the response of the lower limb to military drill training and the etiology of these responses in the development of lower limb stress fractures.

The use of drilling by the U.S. Antarctic program

This report on drilling in the Antarctic has been prepared by the U.S. National Science Foundation (NSF) to assist principal investigators and others in complying with the National Environmental Policy Act (NEPA) and the Antarctic Treaty of 1961. Implementing regulations for NEPA are spelled out in 40 CFR 1500-1508. Environmental protection under the Antarctic Treaty is addressed in the Protocol on Environmental Protection to the Antarctic Treaty (hereafter referred to as the Protocol), which was adopted by 26 countries in 1991. In the United States, responsibility for compliance with these requirements rests with the NSF Office of Polar Programs (OPP),more » which manages the U.S. Antarctic Program (USAP). The USAP recognizes the potentially profound impacts that its presence and activities can have on the antarctic environment. In its extensive support of operations and research in Antarctica, the USAP uses all practical means to foster and maintain natural conditions while supporting scientific endeavors in a safe and healthful manner. Reducing human impacts on the antarctic environment is a major goal of the USAP. The USAP`s operating philosophy is based on broad yet reasonable and practical assumptions concerning environmental protection. The USAP maintains three year-round stations on the continent to support scientific research. Research and associated support operations at these stations and camps sometimes involve drilling into ice, soil, or ocean sediments. In order to comply with NEPA and the Protocol, it is necessary for principal investigators and others to assess the environmental effects of drilling. This report has been prepared to assist in this process by describing various drilling technologies currently available for use in Antarctica, generally characterizing the potential environmental impacts associated with these drilling techniques, and identifying possible mitigation measures to reduce impacts.« less

Drilling the first horizontal well in the Gulf of Mexico; A case history of East Cameron Block 278 Well B-12

Fisher, E.K.; French, M.R.

East Cameron Block 278 Well B-12 was the first horizontal well drilled in the Gulf of Mexico. This gas well, located in the Texaco Inc. operated Eat Cameron 265 field, was drilled and completed in May 1990. The objective formation was a high-permeability, shallow, unconsolidated gas sand located about 1,450 ft below the mudline (BML). The success of this well proved that horizontal wells are viable alternatives to extended-reach development wells from offshore platforms in the Gulf of Mexico. The cost to drill and complete this horizontal well was less than comparable extended-reach development wells drilled in the same field.more » A minimal increase in drilling costs accompanied by considerable savings in completion costs resulted in favorable economics for the project. Drilling a shallow horizontal well in the Gulf of Mexico presented several challenges.

Climate Change Impacts on Texas Water: A White Paper Assessment of the Past, Present and Future and Recommendations for Action

DOE Office of Scientific and Technical Information (OSTI.GOV)

Banner, Jay L.; Jackson, Charles S.; Yang, Zong-Liang

2010-09-01

Texas comprises the eastern portion of the Southwest region, where the convergence of climatological and geopolitical forces has the potential to put extreme stress on water resources. Geologic records indicate that Texas experienced large climate changes on millennial time scales in the past, and over the last thousand years, tree-ring records indicate that there were significant periods of drought in Texas. These droughts were of longer duration than the 1950s 'drought of record' that is commonly used in planning, and they occurred independently of human-induced global climate change. Although there has been a negligible net temperature increase in Texas overmore » the past century, temperatures have increased more significantly over the past three decades. Under essentially all climate model projections, Texas is susceptible to significant climate change in the future. Most projections for the 21st century show that with increasing atmospheric greenhouse gas concentrations, there will be an increase in temperatures across Texas and a shift to a more arid average climate. Studies agree that Texas will likely become significantly warmer and drier, yet the magnitude, timing, and regional distribution of these changes are uncertain. There is a large uncertainty in the projected changes in precipitation for Texas for the 21st century. In contrast, the more robust projected increase in temperature with its effect on evaporation, which is a dominant component in the region's hydrologic cycle, is consistent with model projections of frequent and extended droughts throughout the state. For these reasons, we recommend that Texas invest resources to investigate and anticipate the impacts of climate change on Texas water resources, with the goal of providing data to inform resource planning. This investment should support development of (1) research programs that provide policy-relevant science; (2) education programs to engage future researchers and policy-makers; and (3) connections between policy-makers, scientists, water resource managers, and other stakeholders. It is proposed that these goals may be achieved through the establishment of a Texas Climate Consortium, consisting of representatives from academia, industry, government agencies, water authorities, and other stakeholders. The mission of this consortium would be to develop the capacity to provide decision makers with the information needed to develop adaptation strategies in the face of future climate change and uncertainty.« less

Smaller Footprint Drilling System for Deep and Hard Rock Environments; Feasibility of Ultra-High-Speed Diamond Drilling

DOE Office of Scientific and Technical Information (OSTI.GOV)

TerraTek, A Schlumberger Company

2008-12-31

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high rotational speeds (greater than 10,000 rpm). The work includes a feasibility of concept research effort aimed at development that will ultimately result in the ability to reliably drill 'faster and deeper' possibly with smaller, more mobile rigs. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration (ROP) rock cutting with substantially lower inputs of energymore » and loads. The significance of the 'ultra-high rotary speed drilling system' is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm - usually well below 5,000 rpm. This document provides the progress through two phases of the program entitled 'Smaller Footprint Drilling System for Deep and Hard Rock Environments: Feasibility of Ultra-High-Speed Diamond Drilling' for the period starting 30 June 2003 and concluding 31 March 2009. The accomplishments of Phases 1 and 2 are summarized as follows: (1) TerraTek reviewed applicable literature and documentation and convened a project kick-off meeting with Industry Advisors in attendance (see Black and Judzis); (2) TerraTek designed and planned Phase I bench scale experiments (See Black and Judzis). Improvements were made to the loading mechanism and the rotational speed monitoring instrumentation. New drill bit designs were developed to provided a more consistent product with consistent performance. A test matrix for the final core bit testing program was completed; (3) TerraTek concluded small-scale cutting performance tests; (4) Analysis of Phase 1 data indicated that there is decreased specific energy as the rotational speed increases; (5) Technology transfer, as part of Phase 1, was accomplished with technical presentations to the industry (see Judzis, Boucher, McCammon, and Black); (6) TerraTek prepared a design concept for the high speed drilling test stand, which was planned around the proposed high speed mud motor concept. Alternative drives for the test stand were explored; a high speed hydraulic motor concept was finally used; (7) The high speed system was modified to accommodate larger drill bits than originally planned; (8) Prototype mud turbine motors and the high speed test stand were used to drive the drill bits at high speed; (9) Three different rock types were used during the testing: Sierra White granite, Crab Orchard sandstone, and Colton sandstone. The drill bits used included diamond impregnated bits, a polycrystalline diamond compact (PDC) bit, a thermally stable PDC (TSP) bit, and a hybrid TSP and natural diamond bit; and (10) The drill bits were run at rotary speeds up to 5500 rpm and weight on bit (WOB) to 8000 lbf. During Phase 2, the ROP as measured in depth of cut per bit revolution generally increased with increased WOB. The performance was mixed with increased rotary speed, with the depth cut with the impregnated drill bit generally increasing and the TSP and hybrid TSP drill bits generally decreasing. The ROP in ft/hr generally increased with all bits with increased WOB and rotary speed. The mechanical specific energy generally improved (decreased) with increased WOB and was mixed with increased rotary speed.« less

Although major progress in Arctic Ocean research has been made during the last decades, the knowledge of its short- and long-term paleoceanographic and paleoclimatic history as well as its plate-tectonic evolution is much behind that from the other world's oceans. That means - despite the importance of the Arctic in the climate system - the data base we have from this area is still very weak, and large parts of the climate history have not been recovered at all in sedimentary sections. This lack of knowledge is mainly caused by the major technological/ logistic problems in reaching this permanently ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. With the successful completion of IODP Expedition 302 ("Arctic Coring Expedition" - ACEX), the first Mission Specific Platform (MSP) expedition within the Integrated Ocean Drilling Program - IODP, a new era in Arctic research has begun. For the first time, a scientific drilling in the permanently ice-covered Arctic Ocean was carried out, penetrating about 430 meters of Quaternary, Neogene, Paleogene and Campanian sediment on the crest of Lomonosov Ridge close to the North Pole. The success of ACEX has certainly opened the door for further scientific drilling in the Arctic Ocean, and will frame the next round of questions to be answered from new drill holes to be taken during the next decades. In order to discuss and plan the future of scientific drilling in the Arctic Ocean, an international workshop was held at the Alfred Wegener Institute (AWI) in Bremerhaven/Germany, (Nov 03-05, 2008; convenors: Bernard Coakley/University of Alaska Fairbanks and Ruediger Stein/AWI Bremerhaven). About 95 scientists from Europe, US, Canada, Russia, Japan, and Korea, and observers from oil companies participated in the workshop. Funding of the workshop was provided by the Consortium for Ocean Leadership (US), the European Science Foundation, the Arctic Ocean Sciences Board, and the Nansen Arctic Drilling Program as well as by sponsorships from British Petroleum, ConocoPhillips, ExxonMobil, Norwegian Petroleum Directorate, StatoilHydro, and Shell International. The major targets of the workshop were: (1) to bring together an international group of Arctic scientists, young scientists and ocean drilling scientists to learn and exchange ideas, experience and enthusiasm about the Arctic Ocean; (2) to develop a scientific drilling strategy to investigate the tectonic and paleoceanographic history of the Arctic Ocean and its role in influencing the global climate system; (3) to summarize the technical needs, opportunities, and limitations of drilling in the Arctic; (4) to define scientific and drilling targets for specific IODP-type campaigns in Arctic Ocean key areas to be finalized in the development of drilling proposals. Following overview presentations about the history of the Arctic Ocean, legacy of high-latitude ocean drilling, existing site-survey database, technical needs for high-latitude drilling, possibilities of collaboration with industry, and the process of developing ocean-drilling legs through IODP, the main part of the workshop was spent in thematic and regional break-out groups discussing the particular questions to be addressed by drilling and the particular targets for Arctic scientific drilling. Within the working groups, key scientific questions (related to the overall themes paleoceanography, tectonic evolution, petrology/geochemistry of basement, and gas hydrates) and strategies for reaching the overall goals were discussed and - as one of the main results - core groups for further developing drilling proposals were formed. Based on discussions at this workshop, approximately ten new pre-proposals are planned to be submitted to IODP for the April 01- 2009 deadline. We hope that the development of new scientific objectives through the pre-proposal process will help reshape plans for scientific ocean drilling beyond 2013 and direct the program north towards these critical priorities and advance exploration of the Arctic.

In this work we develop nonlinear mathematical models describing coupled lateral vibrations of a rotating drill string under the effect of external supersonic gas and internal fluid flows. An axial compressive load and a torque also affect the drill string. The mathematical models are derived by the use of Novozhilov's nonlinear theory of elasticity with implementation of Hamilton's variation principle. Expressions for the gas flow pressure are determined according to the piston theory. The fluid flow is considered as added mass inside the curved tube of the drill string. Using an algorithm developed in the Mathematica computation program on the basis of the Galerkin approach and the stiffness switching method the numerical solution of the obtained approximate differential equations is found. Influences of the external loads, drill string angular speed of rotation, parameters of the gas and fluid flows on the drill string vibrations are shown.
