Northern Gulf of Mexico Continental Shelf Stock

waters from 20 to 200m deep in the northern Gulf from the U.S.-Mexican border to the Florida Keys (Figure 1). Both “coastal ” and “offshore ” ecotypes of bottlenose dolphins occur in the Gulf of Mexico (Hersh and Duffield 1990; LeDuc and Curry 1998). The Continental Shelf Stock probably consists of a mixture of both the coastal and offshore ecotypes. The offshore and coastal ecotypes are genetically distinct using both mitochondrial and nuclear markers (Hoelzel et al. 1998). In the northwestern Atlantic, Torres et al. (2003) found a statistically significant break in the distribution of the ecotypes at 34 km from shore. The offshore ecotype was found exclusively seaward of 34km and in waters deeper than 34 m. Within 7.5km of shore, all animals were of the coastal ecotype. The continental shelf is much wider in the Gulf of Mexico so these results may not apply. The continental shelf stock range may extend into Mexican and Cuban territorial waters; however, there are no available estimates of either abundance or mortality from those countries. A stranded dolphin from the Florida Panhandle was rehabilitated and released over the shelf off western Florida, and traveled into the Atlantic Ocean (Wells et al. 1999). The bottlenose dolphins inhabiting waters <20m deep in

Mid-Atlantic Regional Wind Energy Institute  

DOE Green Energy (OSTI)

As the Department of Energy stated in its 20% Wind Energy by 2030 report, there will need to be enhanced outreach efforts on a national, state, regional, and local level to communicate wind development opportunities, benefits and challenges to a diverse set of stakeholders. To help address this need, PennFuture was awarded funding to create the Mid-Atlantic Regional Wind Energy Institute to provide general education and outreach on wind energy development across Maryland, Virginia, Delaware, Pennsylvania and West Virginia. Over the course of the two-year grant period, PennFuture used its expertise on wind energy policy and development in Pennsylvania and expanded it to other states in the Mid-Atlantic region. PennFuture accomplished this through reaching out and establishing connections with policy makers, local environmental groups, health and economic development organizations, and educational institutions and wind energy developers throughout the Mid-Atlantic region. PennFuture conducted two regional wind educational forums that brought together wind industry representatives and public interest organizations from across the region to discuss and address wind development in the Mid-Atlantic region. PennFuture developed the agenda and speakers in collaboration with experts on the ground in each state to help determine the critical issue to wind energy in each location. The sessions focused on topics ranging from the basics of wind development; model ordinance and tax issues; anti-wind arguments and counter points; wildlife issues and coalition building. In addition to in-person events, PennFuture held three webinars on (1) Generating Jobs with Wind Energy; (2) Reviving American Manufacturing with Wind Power; and (3) Wind and Transmission. PennFuture also created a web page for the institute (http://www.midatlanticwind.org) that contains an online database of fact sheets, research reports, sample advocacy letters, top anti-wind claims and information on how to address them, wind and wildlife materials and sample model ordinances. Video and presentations from each in-person meeting and webinar recordings are also available on the site. At the end of the two-year period, PennFuture has accomplished its goal of giving a unified voice and presence to wind energy advocates in the Mid-Atlantic region. We educated a broad range of stakeholders on the benefits of wind energy and gave them the tools to help make a difference in their states. We grew a database of over 500 contacts and hope to continue the discussion and work around the importance of wind energy in the region.

Mid-Atlantic Wind - Overcoming the Challenges  

SciTech Connect

This study, supported by the US Department of Energy, Wind Powering America Program, Maryland Department of Natural Resources and Chesapeake Bay Foundation, analyzed barriers to wind energy development in the Mid-Atlantic region along with options for overcoming or mitigating them. The Mid-Atlantic States including Delaware, Maryland, North Carolina and Virginia, have excellent wind energy potential and growing demand for electricity, but only two utility-scale projects have been installed to date. Reasons for this apathetic development of wind resources were analyzed and quantified for four markets. Specific applications are: 1) Appalachian mountain ridgeline sites, 2) on coastal plains and peninsulas, 3) at shallow water sites in Delaware and Chesapeake Bays, Albemarle and Pamlico Sounds, and 4) at deeper water sites off the Atlantic coast. Each market has distinctly different opportunities and barriers. The primary barriers to wind development described in this report can be grouped into four categories; state policy and regulatory issues, wind resource technical uncertainty, economic viability, and public interest in environmental issues. The properties of these typologies are not mutually independent and do interact. The report concluded that there are no insurmountable barriers to land-based wind energy projects and they could be economically viable today. Likewise potential sites in sheltered shallow waters in regional bay and sounds have been largely overlooked but could be viable currently. Offshore ocean-based applications face higher costs and technical and wind resource uncertainties. The ongoing research and development program, revision of state incentive policies, additional wind measurement efforts, transmission system expansion, environmental baseline studies and outreach to private developers and stakeholders are needed to reduce barriers to wind energy development.

Potential alternative energy technologies on the Outer Continental Shelf.  

SciTech Connect

This technical memorandum (TM) describes the technology requirements for three alternative energy technologies for which pilot and/or commercial projects on the U.S. Outer Continental Shelf (OCS) are likely to be proposed within the next five to seven years. For each of the alternative technologies--wind, wave, and ocean current--the TM first presents an overview. After each technology-specific overview, it describes the technology requirements for four development phases: site monitoring and testing, construction, operation, and decommissioning. For each phase, the report covers the following topics (where data are available): facility description, electricity generated, ocean area (surface and bottom) occupied, resource requirements, emissions and noise sources, hazardous materials stored or used, transportation requirements, and accident potential. Where appropriate, the TM distinguishes between pilot-scale (or demonstration-scale) facilities and commercial-scale facilities.

Impacts of Increased Access to Oil & Natural Gas Resources in the Lower 48 Federal Outer Continental Shelf (released in AEO2007)  

Reports and Publications (EIA)

This analysis was updated for AEO2009: Impact of Limitations on Access to Oil and Natural Gas Resources in the Federal Outer Continental ShelfThe OCS is estimated to contain substantial resources of crude oil and natural gas; however, some areas of the OCS are subject to drilling restrictions. With energy prices rising over the past several years, there has been increased interest in the development of more domestic oil and natural gas supply, including OCS resources. In the past, Federal efforts to encourage exploration and development activities in the deep waters of the OCS have been limited primarily to regulations that would reduce royalty payments by lease holders. More recently, the States of Alaska and Virginia have asked the Federal Government to consider leasing in areas off their coastlines that are off limits as a result of actions by the President or Congress. In response, the Minerals Management Service (MMS) of the U.S. Department of the Interior has included in its proposed 5-year leasing plan for 2007-2012 sales of one lease in the Mid-Atlantic area off the coastline of Virginia and two leases in the North Aleutian Basin area of Alaska. Development in both areas still would require lifting of the current ban on drilling.

Continental Shelf Research 26 (2006) 194--205  

E-Print Network (OSTI)

The benthic communities of the deep insular shelf at the Hind Bank marine conservation district (MCD), an important spawning aggregation site for groupers, were studied with the Seabed autonomous underwater vehicle (AUV) at depths between 32 and 54 m. Four digital phototransects provided data on benthic species composition and abundance of the insular shelf off St. Thomas, US Virgin Islands. Within the western side of the MCD, well-developed coral reefs with 43% mean living coral cover were found. The Montastrea annularis complex was dominant at all four sites between 33 and 47 m, the depth range where reefs were present. Maximum coral cover found was 70% at depths of 38--40 m. Quantitative determinations of sessile benthic populations, as well as the presence of motile megabenthic invertebrates and algae were obtained. The Seabed AUV provided new quantitative and descriptive information of a unique coral reef habitat found within this deeper insular shelf area.

Epibenthic invertebrates and fishes of the continental shelf of the northwestern Gulf of Mexico  

E-Print Network (OSTI)

Data from 34 epibenthic trawls were made on the continental shelf of the northwestern Gulf of Mexico between depths 13 and 400 meters. These took 6,468 individuals belonging to 251 species of demersal fishes and invertebrates, with a mean number of 287 individuals per hectare. The average biomass for all the assemblages was 294 mg/m2 (0.294 g/m2), and the average diversity (H') was 2.0. Hypoxic conditions were not found during the investigation. There was no correlation found between the number of species and depth. Biomass and diversity were not statistically significant between nearshore and offshore. A relatively high number of species were collected from the northwestern Gulf of Mexico compared with the northeastern Gulf; in addition, northwestern Gulf diversity lies between stable tropical shelves and those in temperate latitudes. Evaluation of the percentage similarity indices between stations showed low similarity among the assemblages.

Phytoplankton distributions and species composition across the Texas-Louisiana continental shelf during two flow regimes of the Mississippi River  

E-Print Network (OSTI)

Phytoplankton abundance and species composition were examined over the Texas-Louisiana continental shelf during May 1992 and May 1993, as part of a phytoplankton diversity study funded by the Office of Naval Research. Phytoplankton distribution data were assessed in relation to the hydrography and physical processes on the shelf, which were studied as part of the Texas-Louisiana Shelf Circulation and Transport Processes Study (LATEX A). Phytoplankton group distributions from 1992 , which was an average flow year for the Mississippi River, were compared with observations from 1993, which was a record flow year. Water samples for phytoplankton determinations were examined at 22 locations on cross-shelf transacts from 90.5' to 94.0'W longitude. Samples were collected at the surface and the chlorophyll maximum from Niskin bottles attached to a Sea-Bird SBE911plus CTD, preserved in 1% glutaraldehyde, and analyzed using the Uterm6hl method and the inverted-microscope technique. Unique phytoplankton distributions and regionspecific hydrography and physical processes were found on the inner, middle, and outer shelf during both flow regimes. Some differences were found in May 1993 due to the record river discharge. In 1992 and 1993, the inner shelf was diatom dominated, and was characterized by the highest nutrient and lowest safety values. River discharge and associated nutrients were focused by the localized downcoast flow predominant on the inner shelf area during the month of May. Water column stability decreased moving from the eastern part of the shelf to the western part in May 1992. The opposite regime was present in May 1993. Inner shelf nutrient concentrations in May 1993 were approximately double those in May 1992. The increased river discharge in 1993 caused a dramatic shift in dominant diatom species to Skeletonema costatum (Grevifle) Grunow, which is found in a range of salinities, temperatures, and depths. Chain-forming diatom and others were predominant in both years. On the middle shelf, the presence of tychopelagic diatoms reflected the possibility of benthic regeneration of nutrients and resuspension into the upper water column. This flux from the benthos supported the phytoplankton community on the middle shelf, where a near-bottom chlorophyll maximum was found. Lower concentrations of phytoplankton were present on the middle shelf than the inner shelf during both years. The upper 30-70 m of the water column on the middle shelf were found to be oligotrophic, so smaller or more motile cers such as dinoflagenates, microflagellates, and coccolithophorids became more dominant. The outer shelf upper water column was nutrient-poor as well during both years, and dinoflageuates, microflagellates, and coccolithophorids were even more dominant than on the middle shelf. The diatom population decreased more moving from the middle to the outer shelf. Effects of a warm core Loop Current eddy were evident on the outer shelf area. Upwelling processes shallower than 100 m may provide a means of supporting the phytoplankton population at the chlorophyll maximum on the outer shelf. The location of the increased volume of river water across the shelf in May 1993 was identified based on the increase in overall phytoplankton abundance in May 1993.

West Florida Continental Shelf: a study of geothermal flows and other processes affecting radionuclides and trace metals. Progress report, October 1, 1979-July 1, 1980  

DOE Green Energy (OSTI)

Research progress is reported for the period October 1979-July 1980. Physical and chemical investigations have been made of the single known geothermal discharge on the West Florida Continental Shelf. It was discovered the discharge phenomenon is of regional extent. The origin of the discharges is normal seawater which enters the substrate of the Floridian plateau. The discharges are enriched in Ra 226 and Rn 222, heavy metals (Pb, Ca), and calcium, and depleted in magnesium. The effects of these thermal discharges on the shelf environment were investigated.

The distribution and optical response of particles on the continental shelf and their relationship to cross-isopycnal mixing  

E-Print Network (OSTI)

The relationships of optics, particles, and hydrography to shelf mixing processes were analyzed on a mid-continental shelf south of New England. The objectives were to characterize the types, sizes and sources of particles present in the water column and their effects on optics during conditions of strong stratification (late summer) and weak stratification (spring) and to determine how the particles and optics change over time in response to different forcing functions (wind, surface gravity waves, internal waves, solibors - large scale internal waves- and tides). An unexpected opportunity was presented by the passage of Hurricane Edouard close to the sampling site. Under both strong and weak stratification, surface oaters had high values of fluorescence, particulate organic carbon, and chlorophyll a. Mid-waters contained higher concentrations of particulate organic carbon than bottom oaters, but the optical characteristics of particles more closely resembled those of bottom waters (resuspended and adverted material). Strongly stratified conditions typically exhibited little mixing, with the exception of when extreme forcing events, such as the hurricane, passed through the sampling site. Most of the events sampled during the summer cruise were the result of addiction rather than mixing. Spring conditions included weakly stratified waders with frequent wind events (Nor'easters). Strong forcing events caused surface mixing initially, but solar heating stratified surface waders and gradually inhibited mixing. Particle size distribution changed with stratification. A dramatic increase was observed with the passage of the hurricane, and an initial increase in large particles followed by a substantial increase in smaller particles was observed during a spring phytoplankton bloom. Spring particle settling flux was 3 times higher in the bottom 40 meters than during the previous summer. Relationships between optics and discrete samples generally correlate better under mixed conditions than stratified conditions. During the stratified period, particle distributions were constrained by density layers, where as during weakly stratified periods, the waders were more mixed, leading to a more uniform distribution of particulate matter in the surface and the bottom waters.

Species profiles: Life histories and environmental requirements of coastal fishes and invertebrates (Mid-Atlantic)  

Science Conference Proceedings (OSTI)

Species profiles are literature summaries of the life history, distribution and environmental requirements of coastal fishes and invertebrates. Profiles are prepared to assist with environmental impact assessment. The Atlantic menhaden (Brevoortia tyrannus) is an important commercial fish along the Atlantic coast. In the South Atlantic Region, Atlantic menhaden spawn during winter in continental shelf waters. Adults then move inshore and northward in spring; some move into estuaries as far as the brackish-freshwater boundary. Atlantic menhaden larvae in the South Atlantic Region enter estuaries after 1 to 3 months at sea. Young fish move into the shallow regions of estuaries and seem to prefer vegetated marsh habitats. Atlantic menhaden are size-selective plankton feeders as larvae, and filter feeders as juveniles and adults. Due to their large population size, individual growth rates, and seasonal movements, Atlantic menhaden annually consume and redistribute large amounts of energy and materials. They are also important prey for large game fishes such as bluefish (Pomatomus saltatrix), striped bass (Morone saxatilis), and bluefin tuna (Thunnus thynnus). The Atlantic menhaden is associated with estuarine and nearshore systems during all phases of its life cycle. Young menhaden require these food-rich habitats to survive and grown. Destruction of estuarine wetlands has decreased nursery habitat available to Atlantic menhaden and other estuarine wetlands has decreased nursery habitat available to Atlantic menhaden and other estuarine-dependent species. 115 refs., 2 figs., 2 tabs.

Economic and legal aspects of the organization of planning and construction of structures on the Continental Shelf of Arctic Seas of Russia  

SciTech Connect

At the current stage of development of Russia`s economy the problem arises of refining the concept and working out a strategy of developing the oil gas resources of the continental shelf. The given concept determines the main strategic directions with respect to the disposition, volumes, and scope of works, creation and use of special equipment, structures, and floating equipment, determination of the extent and dynamics of investments, evaluation of the potential possibilities of various financial sources, etc. Strategy is based on the fairly long-term (15-20 years) cost effectiveness of exploration and development of offshore oil and gas reserves governed by the high geologic prospects and poor study of the continental shelf of Russia. The approach to the solution of this problem obviously, should provide for the follow stages: Planning an exploration program realized mainly by centralized budgetary funds. The second stage is a prediction of the results of the competition, i.e., prediction of the number of specific blocks being claimed. A special problem is the selection of the form of licensing agreement. The existing legislation, particularly the Russian Federation Mineral Resources Law, provides for forms of concession and production sharing in addition to the traditional leasing form. One of the problems is the absence of an official division of Russian water areas according to their status: territoral waters, 200-mile exclusive (economic) zone, and continental shelf. Legal problems begin with the presence of variant readings in the formulation of the concepts of three aforementioned zones. All these problems either directly or indirectly determine the economic conditions and successfulness of the converted and other enterprises and organizations developing offshore oil and gas resources.

The Roles of Advection and In Situ Growth in Determining the Dynamics of Continental Shelf Zooplankton: High Frequency Measurements of Zooplankton Biomass Coupled with Measurements of Secondary Productivity in the Middle Atlantic Bight  

DOE Green Energy (OSTI)

Evaluation of the role of continental margins in planetary carbon cycles can be approached in various ways, with the extremes being knowledge generated either by large-scale studies of a few basic characteristics of the carbon cycle of shelves worldwide (comparative approach) or by temporally intensive studies of a few sites selected to typify contrasting processes. Mechanisms of cross-shelf transfer, for example, are presently of great interest and within the US there are at least four differing continental shelf environments in which cross-shelf processes are driven by storms (southern Bering Sea, northeastern US), by jets and eddies (northern California coast), by freshwater runoff (Bering Sea, Gulf of Mexico), and by frontal meanders and filaments of the Gulf Stream (southeastern US). Because the type and magnitude of the physical forcing, and its variability on an annual scale, are fundamental to the response of the carbon cycle, investigation of each of these shelves would offer insight useful to predictive global understanding of the carbon cycle on continental shelves.

Microbial community structure of hydrothermal deposits from geochemically different vent fields along the Mid-Atlantic Ridge  

Science Conference Proceedings (OSTI)

To evaluate the effects of local fluid geochemistry on microbial communities associated with active hydrothermal vent deposits, we examined the archaeal and bacterial communities of 12 samples collected from two very different vent fields: the basalt-hosted Lucky Strike (37 17'N, 32 16.3'W, depth 1600-1750 m) and the ultramafic-hosted Rainbow (36 13'N, 33 54.1'W, depth 2270-2330 m) vent fields along the Mid-Atlantic Ridge (MAR). Using multiplexed barcoded pyrosequencing of the variable region 4 (V4) of the 16S rRNA genes, we show statistically significant differences between the archaeal and bacterial communities associated with the different vent fields. Quantitative polymerase chain reaction (qPCR) assays of the functional gene diagnostic for methanogenesis (mcrA), as well as geochemical modelling to predict pore fluid chemistries within the deposits, support the pyrosequencing observations. Collectively, these results show that the less reduced, hydrogen-poor fluids at Lucky Strike limit colonization by strict anaerobes such as methanogens, and allow for hyperthermophilic microaerophiles, like Aeropyrum. In contrast, the hydrogen-rich reducing vent fluids at the ultramafic-influenced Rainbow vent field support the prevalence of methanogens and other hydrogen-oxidizing thermophiles at this site. These results demonstrate that biogeographical patterns of hydrothermal vent microorganisms are shaped in part by large scale geological and geochemical processes.

Continental drilling  

DOE Green Energy (OSTI)

The Workshop on Continental Drilling was convened to prepare a report for submission to the US Geodynamics Committee with respect to the contribution that could be made by land drilling to resolve major problems of geodynamics and consider the mechanisms by which the responsibility for scientific planning, establishment of priorities, administration, and budgeting for a land-drilling program within the framework of the aims of the Geodynamics Project would best be established. A new and extensive program to study the continental crust is outlined in this report. The Workshop focused on the following topics: processes in the continental crust (mechanism of faulting and earthquakes, hydrothermal systems and active magma chambers); state and structure of the continental crust (heat flow and thermal structure of the crust; state of ambient stress in the North American plate; extent, regional structure, and evolution of crystalline continental crust); short hole investigations; present state and needs of drilling technology; drill hole experimentation and instrumentation; suggestions for organization and operation of drilling project; and suggested level of effort and funding. Four recommendations are set down. 8 figures, 5 tables. (RWR)

Organic geochemistry of continental margin and deep ocean sediments  

Science Conference Proceedings (OSTI)

The objective of this research continues to be the understanding of the complex processes of fossil fuel formation and migration. DOE funded research to date has focused on case histories'' of down-hole well profiles of light hydrocarbons, pyrograms, pyrolysis-GC and -GCMS parameters, and biomarker data from wells in the Louisiana and Texas Gulf Coasts the Alaskan North Slope. In the case of the Alaskan North Slope, geological data and one-dimensional maturation modeling have been integrated in order to better constrain possible source rocks, timing, and migration routes for oil and gas generation and expulsion processes.This period, biomarker analyses and organic petrographic analyses were completed for the Ikpikpuk well. In the case of the Gulf Coast, we have obtained a one-dimensional maturation model of the Cost B-1 well in E. Cameron field of the Louisiana Gulf Coast. The completed E. Cameron data set adds to the enigma of the Gulf Coast oils found on the continental shelf of Louisiana. If significant quantities of the oil are coming from relatively organic lean Tertiary rocks, then non-conventional'' expulsion and migration mechanisms, such as gas dissolved in oil must be invoked to explain the Gulf Coast oils reservoired on the Louisiana continental shelf. We are designing and starting to assemble a hydrous pyrolysis apparatus to follow, the laboratory, rates of generation and expulsion of sediment gases. Initiation of some new research to examine {delta}{sup 13}C of individual compounds from pyrolysis is also described. We are beginning to examine both the laboratory and field data from the Gulf Coast in the context of a Global Basin Research Network (GBRN). The purpose is to better understand subsurface fluid flow processes over geologic time in sedimentary basins and their relation to resource accumulation (i.e., petroleum and metal ores). 58 refs.

{open_quotes}Rosshelf{close_quotes} company and development of the Arctic Shelf of Russia  

Science Conference Proceedings (OSTI)

The Russian {open_quotes}Rosshelf{close_quotes} company for developing the shelf is the nucleus of a new branch of industry for developing oil and gas fields on shelves of Russia, primarily in the Arctic. {open_quotes}Rosshelf{close_quotes}, created on the basis of leading naval defence enterprises, Russia`s largest geological and mining enterprises, and territorial organizations managing the northern regions of Russia, obtained a license in March 1993 for the right to use the natural resources of Europe`s largest Shtokman gas-condensate field and Prirazlomnoe oil field in the Barents Sea and thus has all the conditions and possibilities for the successful organization of oil and gas production on the continental shelf of Russia. The goals of {open_quotes}Rosshelf{close_quotes} are: the production of oil and gas equipment at converted defence enterprises, including under foreign license and for export; the development of oil and gas fields on the continental shelf of Russia; the creation of new prospective technologies for offshore oil and gas production under conditions of the Russian and mainly the arctic shelf. {open_quotes}Rosshelf{close_quotes} should develop the Pechora Sea fields, mainly the Prirazlomnoe oil field with its relatively small depth and distance from the shore. It is planned to develop Europe`s largest Shtokman field at a distance of 600 km from the shore in the course of 10-12 years with expenditures of about $6 billion. The use of defence technologies underlying the activities of {open_quotes}Rosshelf{close_quotes} gives the company a real change to reach the world level of offshore oil- and gas-production technology. Broad cooperation with foreign companies, mainly in the area of engineering, finances, ecology, and safety, planned also for this. Calculations show that already the priority projects of {open_quotes}Rosshelf{close_quotes} will provide 250,000-300,000 highly skilled jobs at Russian defence enterprises.

The North West Shelf Project; Australian LNG facility ahead of schedule  

Science Conference Proceedings (OSTI)

The LNG complex, one of the most important natural resource developments ever undertaken in Australia, will provide a major new export industry for the country. It is based on vast hydrocarbon resources, primarily natural gas, discovered in the early 1970s on the North West Continental Shelf. The project consists of the North Rankin A gas drilling and production platform, a 70-mile subsea pipeline carrying the gas to shore, a domestic gas plant and three LNG trains. A second drilling and production platform, to be located in the Goodwyn field about 23 km from the North Rankin A platform, is now in the development stages. The complex is detailed in this paper.

Tank vessels transferring Outer Continental Shelf (OCS) oil proposed design and equipment standards  

SciTech Connect

The US Coast Guard proposes to require US and foreign flag tank vessels engaged in the transfer of OCS oil in bulk as cargo from an offshore oil exploitation or production facility to shore to have segregated ballast tanks, dedicated clean ballast tanks, or special ballast arrangements by 6/1/80. This proposal would implement the Port and Tanker Safety Act of 1978 and would eliminate the mixing of ballast water and oil, thus reducing operational pollution that could occur if there was a substantial increase in vessel traffic. Comments must be received by 6/16/80.

Benthic study of the continental slope off Cape Hatteras, North Carolina. Volume 3. Appendices  

SciTech Connect

The Point is an area that supports a most productive pelagic fishery, including tuna, swordfish, marlin, and more. The objective of the study is to analyze video tapes from near the Point, in order to provide data on epibenthic, megafaunal invertebrates including species composition, relative abundances, and large scale (1 km) distribution. The Point is not a defined spot on a chart. Although fishermen do use the steep shelf break for location, they generally look for the west wall of the Gulf Stream. The Point and the oil lease site coincidentally occur where the Gulf Stream parts the continental slope, just north of the eastern-most tip of Cape Hatteras.

Wind- and Buoyancy-modulated Along-shore Circulation over the Texas-Louisiana Shelf  

E-Print Network (OSTI)

Numerical experiments are used to study the wind- and buoyancy-modulated along-shore circulation over the Texas-Louisiana continental shelf inshore of 50-m water depth. Most attention is given to circulation in the non-summer flow regime. A major focus of this study is on a unique along-shore flow phenomenon – convergent along- shore flows, which is controlled jointly by wind forcing and buoyancy fluxes from the Mississippi-Atchafalaya river plume. The second problem addresses the forcing effect of buoyancy on the general along-shore circulation pattern over the shelf in non-summer. The convergent along-shore flows are characterized by down-coast flow from the northern shelf encountering up-coast flow from the southern shelf. This phenomenon is explored for both weather band and seasonal timescales. For the weather band, investigations are focused on non-summer convergent events. The formation of convergent flows is primarily caused by along-coast variation in the along-shore component of wind forcing, which in turn is due to the curvature of the Texas-Louisiana coastline. In general, along-shore currents are well correlated with along-shore winds. However, the points of convergence of currents and winds are not co-located; but rather, points of convergence of currents typically occur down-coast of points of convergence of wind. This offset is mainly caused by buoyancy forcing that forces down-coast currents and drives the point of convergence of currents further down-coast. No specific temporal shift pattern is found for the weather-band convergence, whereas monthly

Geologic evolution and aspects of the petroleum geology of the northern East China Sea shelf basin  

Science Conference Proceedings (OSTI)

Analysis of multichannel seismic reflection profiles reveals that the northern East China Sea shelf basin experienced two phases of rifting, followed by regional subsidence. The initial rifting in the Late Cretaceous created a series of grabens and half grabens, filled by alluvial and fluviolacustrine deposits. Regional uplift and folding (Yuquan movement) in the late Eocene-early Oligocene terminated the initial rifting. Rifting resumed in the early Oligocene, while alluvial and fluviolacustrine deposition continued to prevail. A second phase of uplift in the early Miocene terminated the rifting, marking the transition to the postrift phase. The early postrift phase (early Miocene-late Miocene) is characterized by regional subsidence and westward and northwestward marine transgression. Inversion (Longjing movement) in the late Miocene interrupted the postrift subsidence, resulting in an extensive thrust-fold belt in the eastern part of the area. The entire area entered a stage of regional subsidence again and has become a broad continental shelf. Source rocks include synrift lacustrine facies, fluvial shales, and coal beds. Synrift fluvial, lacustrine, and deltaic deposits, postrift littoral and/or shallow-marine sandstones, and fractured basement have the potential to provide reservoirs. Various types of hydrocarbon traps (e.g., faulted anticlines, overthrusts, rollover anticlines, faults, unconformity traps, combination structural-stratigraphic traps, weathered basement, and stratigraphic traps) are recognized, but many of these traps have not been tested.

The basins on the Argentine continental margin  

Science Conference Proceedings (OSTI)

After the stabilization of the central Gondwana Craton, orogenic belts were accreted, as a result of convergence events and an extensive passive margin developed in southwestern Gondwana. Thermal subsidence in Parana, Karoo-Ventania basins and the Late Paleozoic-Early Mesozoic rifts, were modified by the Gondwana breakup and the South Atlantic opening. Early Paleozoic marine transgressions deposited the Table Mountain Group in Ventania. In southwestern Patagonia foreland clastics were deposited. Magmatic arcs and marine units indicate a tectonic trough was formed, alternating with continental sequences, over Late Paleozoic metamorphics and intrusives, resulting from plastered terrains along the Gondwana margin. In Patagonia, Permo-Carboniferous continental and glacio marine clastics infill the basins, while in Ventania, paralic sequences, grade from neritic to continental to the northeast, extending beneath the continental margin. The Triassic-Jurassic rift basins progressed onto regional widespread acid lavas and were infilled by lagoonal organic-rich sequences. Early drift phase built basins transverse to the margin, with fluvio-lacustrine sequences: Salado, Colorado, Valdes-Rawson, San Julian and North Malvinas intracratonic basins, which underwent transtensional faulting. Post-Oxfordian to Neocomian brackish sequences, onlapped the conjugate basins during the margin`s drift, with petroleum systems, as in Austral and Malvinas. In the Valanginian, basic extrusions commenced to form on the continental border, heralding the oceanic phase. Due to thermal subsidence, offlaping sediments prograded onto the remaining half-grabens. Several petroleum systems, proven and hypothetical, are identified in this region.

Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments that Contain Hydrates and High Concentrations of Methane Authors: Colwell, F. (speaker, Oregon State University), Hangsterfer, A., Brodie, E., Daly, R., Holland, M., Briggs, B., Carini, P., Torres, M., Kastner, M., Long, P., Schaef, H., Delwiche, M., Winters, W., and Riedel, M. Venue: American Geophysical Union’s fall meeting in San Francisco, CA, December 10–14, 2007 (http://www.agu.org/meetings/fm07/ [external site]). Abstract: Deep subseafloor sediments with high concentrations of organic carbon and microbially generated methane contain microbial communities that play an important role in the biogeochemical cycling of carbon. However, there remains a limited understanding of the fine (centimeter)-scale sediment properties (e.g., grain size, presence/absence of hydrates) that determine key microbial attributes in deep marine sediments. This project’s objective is to determine the quantity, diversity, and distribution of microbial communities in the context of abiotic properties in gas-rich marine sediments. DNA was extracted from deep marine sediments cored from various continental shelf locations, including offshore India and the Cascadia Margin. Abiotic characterization of the same sediments included grain size analysis, chloride concentrations in sediment pore waters, and presence of hydrates in the sediments as determined by thermal anomalies. As in past studies of such systems, most of the samples yielded low levels of DNA (0.3-1.5 ng/g of sediment). Bacterial DNA appeared to be more easily amplified than archaeal DNA. Initial attempts to amplify DNA using primers specific for the methanogen functional gene, methyl-CoM-reductase, were unsuccessful. Infrequently, cores from relatively shallow sediments (e.g., 0.5 mbsf Leg 204, 1251B-1H) from central (Hydrate Ridge) and northern (offshore Vancouver Island) Cascadia and from India’s eastern margin contained macroscopically visible, pigmented biofilms. One of these biofilms was composed of high concentrations of cell clusters when viewed microscopically. The predominant cells in the Hydrate Ridge biofilm were large (ca. 10 um) cocci, and preliminary characterization of the 16S rDNA amplified and sequenced from this biofilm suggests the prevalence of a microbe with 97% similarity to mycobacteria. These discrete biofilm communities appear to be distinctive relative to the normally sparse distribution of cells in the sediments. By determining how the abiotic properties of deep marine sediments control the numbers and distribution of microbial communities that process organic matter, project researchers hope to provide better parameters for computational models that describe carbon cycling in these systems.

From 1982 through 2008, Congress annually enacted appropriations riders prohibiting the Minerals Management Service (MMS) of the U.S. Department of the Interior from conducting activities related to leasing, exploration, and production of oil and natural gas on much of the Federal OCS. Further, a separate executive ban (originally put in place in 1990 by President George H.W. Bush and later extended by President William J. Clinton through 2012) also prohibited leasing on the OCS, with the exception of the Western Gulf of Mexico, portions of the Central and Eastern Gulf of Mexico, and Alaska. In combination, those actions prohibited drilling along the Atlantic and Pacific coasts, in the eastern Gulf of Mexico, and in portions of the central Gulf of Mexico. The Gulf of Mexico Energy Security Act of 2006 (Public Law 109-432) imposed yet a third ban on drilling through 2022 on tracts in the Eastern Gulf of Mexico that are within 125 miles of Florida, east of a dividing line known as the Military Mission Line, and in the Central Gulf of Mexico within 100 miles of Florida.

Ross Ice Shelf in situ radio-frequency ice attenuation  

E-Print Network (OSTI)

We have measured the in situ average electric field attenuation length for radio-frequency signals broadcast vertically through the Ross Ice Shelf. We chose a location, Moore Embayment, south of Minna Bluff, known for its high reflectivity at the ice-sea interface. We confirmed specular reflection and used the return pulses to measure the average attenuation length from 75-1250 MHz over the round-trip distance of 1155 m. We find the average electric field attenuation length to vary from 500 m at 75 MHz to 300 m at 1250 MHz, with an experimental uncertainty of 55 to 15 m. We discuss the implications for neutrino telescopes that use the radio technique and include the Ross Ice Shelf as part of their sensitive volume.

Effects of tensile loading on upper shelf fracture toughness  

Science Conference Proceedings (OSTI)

Constraint has been an important consideration in fracture mechanics from the earliest work that was done to develop the 1974 version of the ASTM Standard E399. O`Dowd and Shih (1991) have proposed that the difference in crack tip stress fields can be quantified in terms of a field quantity that they have call Q. The Q quantity is a function of J, the crack shape and size, the structural geometry, mode of loading and on the level of deformation and can only be calculated from a high resolution elastic-plastic computational analysis. A similar, simpler, but more controversial approach has been suggested by Betegon and Hancock (1991), who use the non-singular term of the elastic, crack singularity solution, called the T-Stress, as a measure of elastic-plastic crack tip constraint. The objective of this work is to develop some upper shelf, elastic-plastic experimental results to attempt to investigate the applicability of the Q and T stress parameters to the correlation of upper shelf initiation toughness and J resistance curves. The first objective was to obtain upper shelf J resistance curves, J{sub Ic}, and tearing resistance results for a range of applied constraint. The J-Q and J-T stress loci were developed and compared with the expectations of the O`Dowd and Shih and the Betegon and Hancock analyses. Constraint was varied by changing the crack length and also by changing the mode of loading from bending to predominantly tensile. The principle conclusions of this work are that J{sub Ic} does not appear to be dependent on T stress or Q while the material tearing resistance is dependent on T stress and Q, with the tearing modulus increasing as constraint decreases.

Midlatitude Continental Convective Clouds Experiment Midlatitude Continental Convective Clouds Experiment Convective processes play a critical role in the Earth's energy balance through the redistribution of heat and moisture in the atmosphere and their link to the hydrological cycle. Accurate representation of convective processes in numerical models is vital towards improving current and future simulations of Earths climate system. Despite improvements in computing power, current operational weather and global climate models are unable to resolve the natural temporal and spatial scales important to convective processes and therefore must turn to parameterization schemes to represent these processes. In turn, parameterization schemes in cloud-resolving models need to be evaluated for their generality and application to a

Impact of Limitations on Access to Oil and Natural Gas Resources in the Federal Outer Continental Shelf (released in AEO2009)  

Reports and Publications (EIA)

The U.S. offshore is estimated to contain substantial resources of both crude oil and natural gas, but until recently some of the areas of the lower 48 OCS have been under leasing moratoria. The Presidential ban on offshore drilling in portions of the lower 48 OCS was lifted in July 2008, and the Congressional ban was allowed to expire in September 2008, removing regulatory obstacles to development of the Atlantic and Pacific OCS.

Miocene structure of Mustang Island, Mustang Island East Addition and part of Matagorda Island, Outer Continental Shelf areas, Gulf of Mexico  

E-Print Network (OSTI)

Understanding the Miocene structure of Mustang Island and the neighboring areas in the northwestern Gulf of Mexico helps to increase knowledge of the geology and hence contribute to petroleum exploration and production in the area. Interpretation of about 1465 miles of multifold, migrated seismic reflection data, integrated with 35 well log data, served to detail the Miocene structure and its evolution. Early Miocene sedimentation resulted in differential loading of mobile substrates of shale. This caused movement of the shale basinward. Further loading caused overlying sediments to yield, forming the Clemente-Tomas fault. This is a listric, down to the basin growth fault, lying on the seaward flanks of a shale ridge. Rollover anticlines characterize the hangingwall blocks of this fault especially in the southwestern part of the study area. These rollover anticlines could be potential hydrocarbon traps. Rapid sedimentation during the Middle Miocene was responsible for the formation of the contemporaneous growth faults of the Corsair-Wanda system. The Corsair fault is an extensive, listric, mostly concave up growth fault that diagonally runs through the area along a southwest-northeast trend. A salt withdrawal syncline separates the Wanda from the Corsair fault. This suggests that the Corsair formed as a result of primary salt withdrawal. Planar rotation of hangingwall blocks of the Corsair fault formed structural highs that are able to accumulate hydrocarbons. Continued sedimentation during the Middle-Upper Miocene caused the underlying salt to undergo secondary withdrawal. This withdrawal caused the overlying sediments to collapse into a half-turtle anticline upon which the Wanda fault appears to detach. The half-turtle anticlines and a series of horsts could be prospective zones of hydrocarbon accumulation. The Wanda fault zone appears to lie along the landward limit of salt deposition in this part of the Gulf of Mexico. The only salt diapir in the area lies immediately basinward of the Wanda fault.

Use of instrumented charpy tests to determine onset of upper-shelf energy  

SciTech Connect

The Charpy V-notch (C/sub v/) upper-shelf energy is usually defined as that temperature range in which the surface of the C/sub v/ specimen exhibits an appearance indicative of a 100 percent ductile fracture. In an attempt to avoid the need for interpretation, the selection of the C/sub v/ upper-shelf energy is based on the results from an instrumented impact test which provides a permanent record of the load-deflection history of a C/sub v/ specimen during the testing sequence. In the brittle-ductile transition temperature regime, a precipitous drop in the load trace occurs. The amount of the drop decreases at higher temperatures until it is zero, and the zero-drop-in-load temperature is identical to the onset of the C/sub v/ upper shelf. This relationship between the drop in load and energy in an instrumented impact test provides incontestable assurance that the C/sub v/ upper shelf has been obtained. This relationship between drop in load and temperature permits a prediction of the onset of the upper-shelf temperature with as few as two instrumented impact tests. It is also shown that nil-ductility temperature (NDT) (determined by the drop-weight test) is released to the C/sub v/ upper shelf. For the SA-508 Class 2 and SA-533 Grade B Class 1 steels employed in the fabrication of pressure vessels for light-water reactors, C/sub v/ testing at NDT + 180$sup 0$F (100$sup 0$C) will provide upper-shelf energy values.

Geologic Framework of the 2005 Keathley Canyon Geologic Framework of the 2005 Keathley Canyon Gas Hydrate Research Well, Northern Gulf of Mexico Authors: D.R. Hutchinson, P.E. Hart, T.S. Collett, K.M. Edwards, and D.C. Twichell, U.S. Geological Survey, and F. Snyder, WesternGeco-Schlumberger. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco, Mexico, May 22-25, 2007 (http://www.agu.org/meetings/ja07/ [external site]). Abstract: The project was located in the Casey Basin in the northern Gulf of Mexico at 1,335 m water depth. A grid of 2-D high-resolution multichannel seismic lines around the drill sites, targeted for imaging depths down to at least 1,000 m subbottom, reveals multiple disconformities that bound seven mappable seismic stratigraphic units. A major disconformity in the middle of the units stands out for its angular baselapping geometry. From the seismic and drilling data, three episodes of sedimentary deposition and deformation are inferred. The oldest episode consists of fine-grained muds deposited during a period of relative stability in the basin (Units E, F, and G). A second episode (Units C and D) consists of large vertical displacements associated with infilling and ponding of sediment. This second interval corresponds with intercalated fine and coarse-grained material in the drill hole, which sampled the thin edges of much thicker units. The final episode (Units A and B) occurred during much-subdued vertical displacement. Hemipelagic drape (Unit A) characterizes the modern seafloor deposits. The basin is mostly filled. Its sill is part of a subsiding graben that is only 10-20 m shallower than the deepest point in the basin, indicating that gravity-driven transport would mostly bypass the basin. Contemporary faulting along the basin margins has selectively reactivated an older group of faults. The intercalated sand and mud deposits of Units C and D are tentatively correlated with late Pleistocene deposition derived from the western shelf-edge delta/depocenter of the Mississippi River, which was probably most active from 320 ka to 70 ka (Winker and Booth, 2000). Gas hydrate occurs within near-vertical fractures in Units E and F of the oldest episode. The presence of sand within the gas hydrate stability zone is not sufficient to concentrate gas hydrate, even though dispersed gas hydrate occurs deeper in the fractured mud/clay-rich sections of Units E and F.

II: Subsurface sequestration of methane-derived carbon in gas-hydrate-bearing marine sediments II: Subsurface sequestration of methane-derived carbon in gas-hydrate-bearing marine sediments HyFlux - Part II: Subsurface sequestration of methane-derived carbon in gas-hydrate-bearing marine sediments Authors: Naehr, T.H., Asper, V., Garcia, O., Kastner, M., Leifer, I., MacDonald, I.R., Solomon, E., Yvon-Lewis, S., and Zimmer, B. Venue: AGU Fall Meeting, San Francisco, CA, December 15-19 2008 -- Session OS25: Methane Flux from Naturally Occurring Marine Gas Hydrates http://www.agu.org Abstract: The recently funded DOE/NETL study "HyFlux: Remote sensing and sea-truth measurements of methane flux to the atmosphere" (see MacDonald et al.: HyFlux - Part I) will combine sea surface, water column and shallow subsurface observations to improve our estimates of methane flux from submarine seeps and associated gas hydrate deposits to the water column and atmosphere along the Gulf of Mexico continental margin and other selected areas world-wide. As methane-rich fluids rise towards the sediment-water interface, they will interact with sulfate-rich pore fluids derived from overlying bottom water, which results in the formation of an important biogeochemical redox boundary, the so-called sulfate-methane interface, or SMI. Both methane and sulfate are consumed within the SMI and dissolved inorganic carbon, mostly bicarbonate (HCO3-) and hydrogen sulfide are produced, stimulating authigenic carbonate precipitation at and immediately below the SMI. Accordingly, the formation of authigenic carbonates in methane- and gas-hydrate-rich sediments will sequester a portion of the methane-derived carbon. To date, however, little is known about the quantitative aspects of these reactions. Rates of DIC production are not well constrained, but recent biogeochemical models indicate that CaCO3 precipitation rates may be as high as 120 µmol cm-2a-1. Therefore, AOM-driven carbonate precipitation must be considered when assessing the impact of gas-hydrate-derived methane on the global carbon cycle.

Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Authors: Robert S. Bowman, New Mexico Technological University, Socorro, NM; Enid J. Sullivan, Los Alamos National Laboratory, Los Alamos, NM; and Lynn E. Katz and Kerry A. Kinney, University of Texas, Austin, TX. Venue: 44th Annual Meeting of the Clay Minerals Society in Santa Fe, NM, June 3–7, 2007 (http://www.clays.org/home/HomeAnnualMeeting.html [external site]). Abstract: About 2.3 billion cubic meters (600 billion gallons) of wastewater (produced water) is generated each year as a byproduct of oil and gas operations in the continental United States. Disposal of this water represents about 10% of the cost of hydrocarbon production. Inexpensive treatment technologies can lower the cost of disposal and generate higher-quality water for other uses. Surfactant-modified zeolite (SMZ) has been shown to effectively sorb a variety of nonpolar organic compounds from water. SMZ was tested as a medium to remove benzene, toluene, ethylbenzene, and xylenes (BTEX) from produced water generated during extraction of coalbed natural gas. BTEX removal is necessary prior to surface discharge of produced waters or as a pretreatment for reverse osmosis. We demonstrated in laboratory column experiments that BTEX-saturated SMZ is readily regenerated by air sparging. There was no loss in BTEX sorption capacity, and a minor decrease in hydraulic conductivity, after 50 sorption/regeneration cycles. Based upon the laboratory results, a pilot-scale produced-water treatment system was designed and tested at a reinjection facility in the San Juan Basin of New Mexico. The SMZ-based system was designed to treat up to 110 liters (30 gallons) of produced water per hour on a continuous basis by running two SMZ columns in series. The system performed as predicted, based on laboratory results, over repeated feed and regeneration cycles during the month-long operation. The BTEX-laden sparge gases were treated with a vapor-phase bioreactor system, resulting in an emissions-free process

ARM - Midlatitude Continental Convective Clouds (jensen-sonde)  

DOE Data Explorer (OSTI)

A major component of the Mid-latitude Continental Convective Clouds Experiment (MC3E) field campaign was the deployment of an enhanced radiosonde array designed to capture the vertical profile of atmospheric state variables (pressure, temperature, humidity wind speed and wind direction) for the purpose of deriving the large-scale forcing for use in modeling studies. The radiosonde array included six sites (enhanced Central Facility [CF-1] plus five new sites) launching radiosondes at 3-6 hour sampling intervals. The network will cover an area of approximately (300)2 km2 with five outer sounding launch sites and one central launch location. The five outer sounding launch sites are: S01 Pratt, KS [ 37.7oN, 98.75oW]; S02 Chanute, KS [37.674, 95.488]; S03 Vici, Oklahoma [36.071, -99.204]; S04 Morris, Oklahoma [35.687, -95.856]; and S05 Purcell, Oklahoma [34.985, -97.522]. Soundings from the SGP Central Facility during MC3E can be retrieved from the regular ARM archive. During routine MC3E operations 4 radiosondes were launched from each of these sites (approx. 0130, 0730, 1330 and 1930 UTC). On days that were forecast to be convective up to four additional launches were launched at each site (approx. 0430, 1030, 1630, 2230 UTC). There were a total of approximately 14 of these high frequency launch days over the course of the experiment.

Structure of continental rifts: Role of older features and magmatism  

SciTech Connect

Recent geological and geophysical studies in several continental rifts have begun to shed light on the details of the processes which govern the structural evolution of these important exploration targets. In Kenya and Tanzania, the classic East African rift has been the object of several investigations which reveal that its location follows the boundary (suture ) between the Tanzanian craton (Archean) and Mozambiquan belt (Proterozoic), The Baikal rift also follows a similar boundary, and the Mid-continent rift of North America appears to do the same. Rifts themselves often act as zones of weakness which are reactivated by younger tectonic regimes. The classic North American example of this effect is the Eocambrian Southern Oklahoma aulacogen which was deformed to create the Anadarko basin and Wichita uplift in the late Paleozoic. The Central basin platform has a similar history although the original rift formed at [approximately]1,100Ma. Integration of geophysical data with petrologic and geochemical data from several rift zones has also provided a new picture of the nature and extent of magmatic modification of the crust. An interesting contradiction is that Phanerozoic rifts, except the Afar region, show little evidence for major magmatic modification of the crust whereas, at least in North America, many Precambrian rifts are associated with very large mafic bodies in the crust. The Kenya rift displays evidence for modification of the lower crust in a two-phase magmatic history, but upper crustal magmatic features are limited to local intrusions associated with volcanoes. In this rift, complex basement structure plays a much more important role than previously realized, and the geophysical signatures of basement structure and magmatism are easy to confuse. If this is also the case in other rifts, additional rift basins remain to be discovered.

Midlatitude Continental Convective Clouds Experiment (MC3E)  

SciTech Connect

Convective processes play a critical role in the Earth’s energy balance through the redistribution of heat and moisture in the atmosphere and subsequent impacts on the hydrologic cycle. Global observation and accurate representation of these processes in numerical models is vital to improving our current understanding and future simulations of Earth’s climate system. Despite improvements in computing power, current operational weather and global climate models are unable to resolve the natural temporal and spatial scales that are associated with convective and stratiform precipitation processes; therefore, they must turn to parameterization schemes to represent these processes. In turn, the physical basis for these parameterization schemes needs to be evaluated for general application under a variety of atmospheric conditions. Analogously, space-based remote sensing algorithms designed to retrieve related cloud and precipitation information for use in hydrological, climate, and numerical weather prediction applications often rely on physical “parameterizations” that reliably translate indirectly related instrument measurements to the physical quantity of interest (e.g., precipitation rate). Importantly, both spaceborne retrieval algorithms and model convective parameterization schemes traditionally rely on field campaign data sets as a basis for evaluating and improving the physics of their respective approaches. The Midlatitude Continental Convective Clouds Experiment (MC3E) will take place in central Oklahoma during the April–May 2011 period. The experiment is a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the National Aeronautics and Space Administration’s (NASA) Global Precipitation Measurement (GPM) mission Ground Validation (GV) program. The field campaign leverages the unprecedented observing infrastructure currently available in the central United States, combined with an extensive sounding array, remote sensing and in situ aircraft observations, NASA GPM ground validation remote sensors, and new ARM instrumentation purchased with American Recovery and Reinvestment Act funding. The overarching goal is to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land that have never before been available. Several different components of convective cloud and precipitation processes tangible to both the convective parameterization and precipitation retrieval algorithm problem are targeted, such as preconvective environment and convective initiation, updraft/downdraft dynamics, condensate transport and detrainment, precipitation and cloud microphysics, spatial and temporal variability of precipitation, influence on the environment and radiation, and a detailed description of the large-scale forcing.

Dynamics of marine pelagic bacterial communities on the Texas-Louisiana shelf  

E-Print Network (OSTI)

Microbial community interactions within many ecosystems are still relatively unknown. Investigating links between environmental dynamics and shifting pelagic bacterial community structures on the Texas-Louisiana shelf, Eubacterial community profiles of Operational Taxonomic Units (OTUs) were generated using Automated Ribosomal Intergenic Spacer Analysis (ARISA) of the 16S rDNA and 23S rDNA intergenic spacer region. This ITS region is highly variable in both length and sequence. Community diversity was assessed by the comparison of ARISA-generated community fingerprints of samples collected from four distinct regions along the Texas-Louisiana shelf in a cross-shelf pattern on 10m, 20m, and 40m isobaths. Incubations of samples with a thymidine analog, 5-Bromodeoxyuridine (BrdU), allowed for the isolation and analysis of the actively growing subset within the total bacterial population. Community composition was determined through the construction of clone libraries for sequencing and putative phyla affiliation of community 16 rRNA genes. Hydrographic data were also collected for analysis of shifts in microbial community diversity correlated with a variety of influential environmental factors. ARISA profiles of Eubacterial species richness suggest strong distinction between the two communities found within Zones A and C along the Texas-Louisiana Shelf. Further analysis of salinity gradients originating from the two main fluvial sources, the Mississippi and the Atchafalaya Rivers, identified possible sources of variation between the individual communities. Whereas composition of these communities remains discrete between regions, the active subset of the population becomes more similar across the shelf through the summer. Possibly due to undersampling of hypoxic sites, no relationship could be determined between hypoxia formation and the Eubacterial community dynamics. Several OTUs within the communities were identifiable as ? - and ? - Proteobacteria, Actinobacteria, Synechococcus, Prochlorococcus, and Cytophaga/Flavobacterium/Bacteroides. Through validation studies of 5-Bromodeoxyuridine field sampling, this study indicates the power of BrdU incorporation and ARISA analysis to study a dynamic environmental system and explore the factors that determine the structure of the pelagic community on the Texas-Louisiana Shelf.

Geochemistry of Precambrian carbonates: 3-shelf seas and non-marine environments of the Archean  

SciTech Connect

A comprehensive whole-rock study of mineralogical, chemical, and isotopic attributes of Archean carbonates suggests that their lithologies and facies have been controlled by tectonic setting. In the first two papers of this series they have shown that the dominant lithology of sedimentary carbonates in greenstone belt settings is limestone. In this paper the authors suggest that the Archean shelf sequences are mostly dolostone, and the contemporaneous lacustrine playa lakes are characterized by limestone facies. The present study is of the shelf environments of the Archean, represented by the Pongola Supergroup of South Africa and the Hamersley Group of Australia. The lacustrine playa examples have been sampled from the Ventersdorp Supergroup of South Africa and the Fortescue Group of Australia. Geological, trace element, and oxygen isotope considerations of the shelf carbonates suggest that their original mineralogy may have been aragonite and that the Pongola dolostones probably represent a direct dolomitization product of this precursor. In contrast, the stabilization of the Hamersley carbonates may have involved an additional step of transformation of a metastable precursor into limestone prior to dolomitization.

Continental margin subsidence and heat flow: important parameters in formation of petroleum hydrocarbons  

Science Conference Proceedings (OSTI)

Passive continental margins have been shown to subside with a 50-My exponentially decaying rate which cannot be explained by isostatic compensation for sediment loading. This suggests that the subsidence is dominated by geodynamic processes similar to those in the deep ocean. Two simple geologic models for continental breakup are developed: (1) attenuation of continental lithosphere; and (2) intrusion of mantle diapirs. These models for rifting give a direct relation between subsidence of passive margins and their surface heat flow through time. On this basis we develop a method of reconstructing the thermal history of sedimentary strata from regional subsidence and sedimentation history. Because generation of petroleum hydrocarbons depends on the intergrated time/temperature history of buried organic material, this reconstruction technique can be used to determine the depth to the oil range of the hydrocarbon generation window in advance of drilling. By way of example, we reconstruct time/temperature/depth plots and estimate hydrocarbon maturity for one site in the Falkland Plateau and three sites in the North Atlantic near Cape Hatteras. In addition to providing a method for evaluating hydrocarbon potential in frontier regions where there is little or no well control, this approach suggests that there may be significant potential for oil and gas generation on the outer part of the continental rise and in deep-sea sedimentary basins. 13 figures, 1 table.

A virtual tall tower network for understanding continental sources and sinks of CO2  

SciTech Connect

Our understanding of the North American terrestrial carbon cycle is limited by both a lack of continental atmospheric CO2 data, and by a need for methods to interpret these and other continental data with confidence. In response to this challenge a rapid expansion of the N. American carbon cycle observational network is underway. This expansion includes a network of continuous, continental CO2 mixing ratio observations being collected at a subset of AmeriFlux towers. Progress in developing this resource includes instrument development, site installation, calibration and intercalibration efforts, and initiation of a uniform data product. Progess in applying these data include proposed methods for interpreting surface layer measurements in atmospheric inversions (the virtual tall towers approach), examination of coherence patterns in continental mixing ratios in response to weather and climate, and application of these mixing ratio measurements in formal atmospheric inversions. Future work will merge these methods with interpretation of flux towers observations of terrestrial carbon fluxes in an effort to create a single coherent diagnosis of North American terrestrial carbon fluxes over a multi-year period.

Smoothed particle hydrodynamics Non-Newtonian model for ice-sheet and ice-shelf dynamics  

SciTech Connect

Mathematical modeling of ice sheets is complicated by the non-linearity of the governing equations and boundary conditions. Standard grid-based methods require complex front tracking techniques and have limited capability to handle large material deformations and abrupt changes in bottom topography. As a consequence, numerical methods are usually restricted to shallow ice sheet and ice shelf approximations. We propose a new smoothed particle hydrodynamics (SPH) non-Newtonian model for coupled ice sheet and ice shelf dynamics. SPH, a fully Lagrangian particle method, is highly scalable and its Lagrangian nature and meshless discretization are well suited to the simulation of free surface ?ows, large material deformation, and material fragmentation. In this paper, SPH is used to study 3D ice sheet/ice shelf behavior, and the dynamics of the grounding line. The steady state position of the grounding line obtained from SPH simulations is in good agreement with laboratory observations for a wide range of simulated bedrock slopes, and density ratios, similar to those of ice and sea water. The numerical accuracy of the SPH algorithm is veri?ed by simulating Poiseuille ?ow, plane shear ?ow with free surface and the propagation of a blob of ice along a horizontal surface. In the laboratory experiment, the ice was represented with a viscous Newtonian ?uid. In the present work, however, the ice is modeled as both viscous Newtonian ?uid and non-Newtonian ?uid, such that the e?ect of non-Newtonian rheology on the dynamics of grounding line was examined. The non-Newtonian constitutive relation is prescribed to be Glen’s law for the creep of polycrystalline ice. A V-shaped bedrock ramp is further introduced to model the real geometry of bedrock slope.

In the experiment, the ice was represented with a viscous newtonian fluid. For consistency, in the described SPH model the ice is also modeled as a viscous newtonian fluid. Typically, ice sheets are modeled as a non-Newtonian fluid, accounting for the changes in the mechanical properties of ice. Implementation of a non-Newtonian rheology in the SPH model is the subject of our ongoing research.

Annual daylighting performance of a passive optical light shelf in sidelit  

NLE Websites -- All DOE Office Websites (Extended Search)

Annual daylighting performance of a passive optical light shelf in sidelit Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Title Annual daylighting performance of a passive optical light shelf in sidelit perimeter zones of commercial buildings Publication Type Report Year of Publication 2013 Authors McNeil, Andrew, and Eleanor S. Lee Keywords bidirectional scattering distribution functions, building energy efficiency, daylighting, Radiance simulations Abstract Sunlight redirecting systems have the potential to significantly offset electric lighting energy use in deep perimeter zones of buildings where the windows are subject to high daylight availability. New Radiance modeling tools have recently been developed and validated, enabling accurate and timely simulation analysis of the annual energy and comfort performance of these optically-complex, anisotropic systems. A parametric study was conducted using these tools to evaluate the performance of a commercially-available passive optical light shelf (OLS) in a 17.4 m deep (57 ft), south-facing open plan office zone in three climates. Daylighting efficiency, discomfort glare, and lighting energy savings with continuous dimming and bi-level switching controls were determined at varying depths within the zone. The OLS decreased lighting energy use significantly throughout the depth of the space and achieved these savings with minimal discomfort glare in the area near the window. Annual lighting energy use intensity was reduced to 1.71-1.82 kWh/ft2-yr (22-27%) over the full depth of the perimeter zone across the three climates modeled (Phoenix, Washington DC, and Minneapolis) compared to a non-daylit zone at 2.34 kWh/ft2-yr. There was a greater occurrence of discomfort glare (3-7% during daytime work hours) if the occupant was in a seated view position looking at the window from the back of the room. The system is passive, needing no adjustment during the day and over the seasons and can be used as a retrofit measure in existing buildings. These results are encouraging and demonstrate how the primary daylit sidelit area can be extended well beyond the defined limits provided by the newly adopted ASHRAE 90.1-2010 code (i.e., 1.0 times the head height of the window).

CO2 Huff-n-Puff Process in a Light Oil Shallow Shelf Carbonate Reservoir  

Science Conference Proceedings (OSTI)

The principal objective of the Sundown Slaughter Unit (SSU) CO2 Huff- n- Puff (H- n- P) project is to determine the feasibility and practicality of the technology in a waterflooded shallow shelf carbonate environment. Sundown Slaughter Unit is the second demonstration site associated with this project, following the unsuccessful test at Central Vacuum Unit. The ultimate goal will be to develop guidelines based on commonly available data that other operators in the industry can use to investigate the applicability of the process within other fields. The technology transfer objective of the project is to disseminate the knowledge gained through an innovative plan in support of the Department of Energy's (DOE) objective of increasing domestic oil production and deferring the abandonment of shallow shelf carbonate (SSC) reservoirs. Tasks associated with this objective are carried out in what is a timely effort for near- term goals. The goal of this Sundown Slaughter Unit Project is to demonstrate the CO2 Huff- n- Puff process in a waterflooded, light oil, shallow shelf carbonate reservoir within the Permian Basin. The CO2 Huff- n- Puff process is a proven enhanced oil recovery technology for Louisiana- Texas gulf coast sandstone reservoirs. The reader is referred to three Society of Petroleum Engineer (SPE) papers, No. 15502, No. 16720 & No. 20208 for a review of the theory, mechanics of the process, and several case histories. The process has even been shown to be moderately effective in conjunction with steam on heavy California crude oils. Although the technology is proven in gulf coast sandstones, it continues to be a very underutilized enhanced recovery option for carbonates. The goal of this technology demonstration is to gain an overall understanding of the reservoir qualities that influence CO2 Huff- n- Puff production responses within a heterogeneous reservoir such as the shallow shelf carbonate environment of the Sundown Slaughter Unit. A generalized reservoir model was developed and used to determine the importance of various geological and operational influences upon the CO2 Huff- n- Puff process at CVU. The findings at CVU would be applied to the demonstration site at SSU without further simulation studies being conducted at SSU.

Performance of commercial off-the-shelf microelectromechanical systems sensors in a pulsed reactor environment  

Science Conference Proceedings (OSTI)

Prompted by the unexpected failure of piezoresistive sensors in both an elevated gamma-ray environment and reactor core pulse tests, we initiated radiation testing of several MEMS piezoresistive accelerometers and pressure transducers to ascertain their radiation hardness. Some commercial off-the-shelf sensors are found to be viable options for use in a high-energy pulsed reactor, but others suffer severe degradation and even catastrophic failure. Although researchers are promoting the use of MEMS devices in radiation-harsh environment, we nevertheless find assurance testing necessary.

Milliwatt generator heat source shelf-life-related pressure-burst capsule evaluations  

DOE Green Energy (OSTI)

Three Milliwatt Generator Heat Source (MWGHS) shelf-life-related capsules were pressure-burst tested after thermal aging. Shelf-life capsules PB-08-03 (MC2893) and MPT-11-33 (MC3599) were tested at 1,010 C and capsule PB-07-13 (MC2893) was tested at 1,100 C. Subsequent to pressure-burst testing, each capsule was bubble-leak tested then metallographically examined. Post-mortem evaluation consisted of metallography, microhardness, scanning electron microscopy (SEM), and oxygen and nitrogen analysis. Capsules PB-08-03 and PB-07-13 failed by elevated temperature stress-rupture in the coarse-grained cap to body welds, as has been documented for previous capsules. Pressure-burst testing of capsule MPT-11-33 was terminated prior to failure after 739 hours on test at 1,010 C, however, microscopic examination of the weld indicated that similar failure had began to occur in the interior portion of the capsule to body weld. Evidence was obtained indicating that metallurgical changes occurred during the pressure-burst test performed at 1,100 C. The metallurgical observations of a preferred site for elevated temperature deformation and fracture (the coarse-grained weld region) and structural instability (the property changes during testing at 1,100 C) need to be considered in component lifetime prediction and modeling efforts.

Changes in cell buoyant density, vesiculation, and the tendency of stored cells to bind autologous IgG antibody directed against polymerized band 3 IgG, all of which are related to red blood cell senescence and increase with refrigerated storage time, have been substantially slowed when red blood cells are treated with CO. Removal of the carbon monoxide from the red blood cells is readily and efficiently accomplished by photolysis in the presence of oxygen so that the stored red blood cells may be safely transfused into a recipient.

MITAS-2009 Expedition, U.S. Beaufort Shelf and Slope—Lithostratigraphy Data Report  

SciTech Connect

The volume of methane released through the Arctic Ocean to the atmosphere and its potential role in the global climate cycle have increasingly become the focus of studies seeking to understand the source and origin of this methane. In 2009, an international, multi-disciplinary science party aboard the U.S. Coast Guard icebreaker Polar Sea successfully completed a trans-U.S. Beaufort Shelf expedition aimed at understanding the sources and volumes of methane across this region. Following more than a year of preliminary cruise planning and a thorough site evaluation, the Methane in the Arctic Shelf/Slope (MITAS) expedition departed from the waters off the coast of Barrow, Alaska in September 2009. The expedition was organized with an international shipboard science team consisting of 33 scientists with the breadth of expertise necessary to meet the expedition goals. NETL researchers led the expedition’s initial core processing and lithostratigraphic evaluations, which are the focus of this report. This data report is focused on the lithostratigraphic datasets from the recovered vibra cores and piston cores. Operational information about the piston and vibra cores such as date acquired, core name, total length, water depth, and geographic location is provided. Once recovered, gas samples were immediately collected from cores. In addition, each core was run through the Geotek multi-sensor core logger for magnetic susceptibility, P-wave velocity, resistivity, and gamma-density measurements (Rose et al., 2010). After the samples and measurements were completed, the cores were split into working and archive halves. Visual core descriptions of the archive half was completed for each core. Samples for shipboard smear slides, coarse fractions, and XRD analyses were collected, as well as corresponding samples for post-cruise grain size analysis from the working half of each core. Line scan images of the split core surfaces were collected post-expedition. The methods used to characterize the lithostratigraphy of the recovered cores are described.

Temperature, salinity, and dissolved oxygen concentrations records reveal the presence of an alongshelf meander, which is manifested vertically and horizontally as a wave-like distribution of the properties in the water column. The observations suggest the meander is a ubiquitous characteristic of the shelf with alongshore spatial scale approximately 50 km and less, which is consistent with the locations of sandy shoals along the coast and the local deformation radius. Twelve numerical experiments using an idealized three-dimensional shelf circulation model were performed to evaluate the relative importance of the variable bottom topography and freshwater forcing on the development, evolution, and scales of the dynamic instabilities. The inclusion of the shoals into the bottom topography showed the development of the dynamic instabilities as the flow passed over the shoals and downstream. Introduction of fresh water onto the shelf resulted in greater salinity differences, and, as a consequence in the formation of the dynamically unstable salinity fronts along the plume edge. The combination of the freshwater forcing and shoaling topography produced competing and complex interactions. Six numerical experiments were analyzed in order to investigate the effect of dynamic instabilities on spatial and temporal patterns of dissolved oxygen concentrations along the shelf. Although a linear relationship between Brunt-Väisälä frequency and dissolved oxygen deficit was expected, a nonlinear loop-like relationship was discovered that reflects the response of biochemical properties to the alongshelf variability of the density field. Comparison of the numerical modeling runs to observations of density and dissolved oxygen concentrations on the Louisiana Shelf reinforces the importance of physical processes such as topographic steering and/or freshwater forcing on the alongshore distribution of physical and biochemical properties. It suggests that the time scales of respiration (~3 days) and buoyancy transfer processes (~5-7 days), associated with the physical processes that are responsible for water column stability and ventilation, are similar to the time scales associated with the benthic respiration rates.

A probabilistic tornado wind hazard model for the continental United States  

SciTech Connect

A probabilistic tornado wind hazard model for the continental United States (CONUS) is described. The model incorporates both aleatory (random) and epistemic uncertainties associated with quantifying the tornado wind hazard parameters. The temporal occurrences of tornadoes within the continental United States (CONUS) is assumed to be a Poisson process. A spatial distribution of tornado touchdown locations is developed empirically based on the observed historical events within the CONUS. The hazard model is an aerial probability model that takes into consideration the size and orientation of the facility, the length and width of the tornado damage area (idealized as a rectangle and dependent on the tornado intensity scale), wind speed variation within the damage area, tornado intensity classification errors (i.e.,errors in assigning a Fujita intensity scale based on surveyed damage), and the tornado path direction. Epistemic uncertainties in describing the distributions of the aleatory variables are accounted for by using more than one distribution model to describe aleatory variations. The epistemic uncertainties are based on inputs from a panel of experts. A computer program, TORNADO, has been developed incorporating this model; features of this program are also presented.

CO2 Huff-n-Puff Process in a Light Oil Shallow Shelf Carbonate Reservoir  

Science Conference Proceedings (OSTI)

The application of cyclic CO2, often referred to as the CO2 Huff-n-Puff process, may find its niche in the maturing waterfloods of the Permian Basin. Coupling the CO2 Huff-n-Puff process to miscible flooding applications could provide the needed revenue to sufficiently mitigate near-term negative cash flow concerns in the capital-intensive miscible projects. Texaco Exploration & Production Inc. and the U. S. Department of Energy have teamed up in an attempt to develop the CO2 Huff-n-Puff process in the Grayburg and San Andres formations which are light oil, shallow shelf carbonate reservoirs that exist throughout the Permian Basin. This cost-shared effort is intended to demonstrate the viability of this underutilized technology in a specific class of domestic reservoir. A significant amount of oil reserves are located in carbonate reservoirs. Specifically, the carbonates deposited in shallow shelf (SSC) environments make up the largest percentage of known reservoirs within the Permian Basin of North America. Many of these known resources have been under waterflooding operations for decades and are at risk of abandonment if crude oil recoveries cannot be economically enhanced 1,2 . The selected sites for this demonstration project are the Central Vacuum Unit waterflood in Lea County, New Mexico and the Sundown Slaughter Field in Hockley County, Texas. Miscible CO2 flooding is the process of choice for enhancing recovery of light oils 3 and already accounts for over 12% of the Permian Basin?s daily production.4 There are significant probable reserves associated with future miscible CO2 projects. However, many are marginally economic at current market conditions due to large up-front capital commitments for a peak response, which may be several years in the future. The resulting negative cash-flow is sometimes too much for an operator to absorb. The CO2 Huff-n-Puff process is being investigated as a near-term option to mitigate the negative cash-flow situation--allowing acceleration of inventoried miscible CO2 projects when coupled together. The CO2 Huff-n-Puff process is a proven enhanced oil recovery technology in Louisiana-Texas Gulf-coast sandstone reservoirs 5,6 . Application seems to mostly confine itself to low pressure sandstone reservoirs 7 . The process has even been shown to be moderately effective in conjunction with steam on heavy California crude oils 8,9 . A review of earlier literature 5,10,11 provides an excellent discussion on the theory, mechanics of the process, and several case histories. Although the technology is proven in light oil sandstones, it continues to be a very underutilized enhanced recovery option for carbonates. However, the theories associated with the CO2 Huff-n-Puff process are not lithology dependent. It was anticipated that this project would show that the application of the CO2 Huff-n-Puff process in shallow shelf carbonates could be economically implemented to recover appreciable volumes of light oil. The goals of the project were the development of guidelines for cost-effective selection of candidate reservoirs and wells, along with estimating recovery potential.

ARM - Midlatitude Continental Convective Clouds - Single Column Model Forcing (xie-scm_forcing)  

Science Conference Proceedings (OSTI)

The constrained variational objective analysis approach described in Zhang and Lin [1997] and Zhang et al. [2001]was used to derive the large-scale single-column/cloud resolving model forcing and evaluation data set from the observational data collected during Midlatitude Continental Convective Clouds Experiment (MC3E), which was conducted during April to June 2011 near the ARM Southern Great Plains (SGP) site. The analysis data cover the period from 00Z 22 April - 21Z 6 June 2011. The forcing data represent an average over the 3 different analysis domains centered at central facility with a diameter of 300 km (standard SGP forcing domain size), 150 km and 75 km, as shown in Figure 1. This is to support modeling studies on various-scale convective systems.

Determinants of alternative fuel vehicle choice in the continental United States.  

SciTech Connect

This paper describes the ongoing investigation into the determinants of alternative fuel vehicle choice. A stated preference vehicle choice survey was conducted for the 47 of the continental U.S. states, excluding California. The national survey is based on and is an extension of previous studies on alternative fuel vehicle choice for the State of California conducted by the University of California's Institute of Transportation Studies (UC ITS). Researchers at UC ITS have used the stated-preference national survey to produce a series of estimates for new vehicle choice models. Three of these models are presented in this paper. The first two of the models were estimated using only the data from the national survey. The third model presented in this paper pools information from the national and California surveys to estimate a true national model for new vehicle choice.

SRNL PHASE II SHELF LIFE STUDIES - SERIES 1 ROOM TEMPERATURE AND HIGH RELATIVE HUMIDITY  

SciTech Connect

The Savannah River National Laboratory (SRNL) Phase II, Series 1 shelf-life corrosion testing for the Department of Energy Standard 3013 container is presented and discussed in terms of the localized corrosion behavior of Type 304 stainless steel in contact with moist plutonium oxide and chloride salt mixtures and the potential impact to the 3013 inner container. This testing was designed to address the influence of temperature, salt composition, initial salt moisture, residual stress and type of oxide/salt contact on the relative humidity inside a 3013 container and the initiation and propagation of localized corrosion, especially stress corrosion cracking. The integrated plan is being conducted by Los Alamos National Laboratory and SRNL. SRNL is responsible for conducting a corrosion study in small scale vessels containing plutonium oxide and chloride salts under conditions of humidity, temperature and oxide/salt compositions both within the limits of 3013 storage conditions as well as beyond the 3013 storage requirements to identify margins for minimizing the initiation of stress corrosion cracking. These worst case conditions provide data that bound the material packaged in 3013 containers. Phase I of this testing was completed in 2010. The Phase II, Series 1 testing was performed to verify previous results from Phase I testing and extend our understanding about the initiation of stress corrosion cracking and pitting that occur in 304L under conditions of room temperature, high humidity, and a specific plutonium oxide/salt chemistry. These results will aid in bounding the safe storage conditions of plutonium oxides in 3013 containers. A substantial change in the testing was the addition of the capability to monitor relative humidity during test exposure. The results show that under conditions of high initial moisture ({approx}0.5 wt%) and room temperature stress corrosion cracking occurred in 304L teardrop coupons in contact with the oxide/salt mixture at times as short as 85 days. In all cases, the cracking appeared to be associated with pitting or localized general corrosion. Crack initiation at other sites, such as surface imperfections or inclusions, cannot be excluded. Cracks appear in most cases to initiate through an intergranular mode and transition to a transgranular mode.

Commercial Off-the-Shelf (COTS) Components and Enterprise Component Information System (eCIS)  

Science Conference Proceedings (OSTI)

The purpose of the project was to develop the processes for using commercial off-the-shelf (COTS) parts for WR production and to put in place a system for implementing the data management tools required to disseminate, store, track procurement, and qualify vendors. Much of the effort was devoted to determining if the use of COTS parts was possible. A basic question: How does the Nuclear Weapons Complex (NWC) begin to use COTS in the weapon Stockpile Life Extension Programs with high reliability, affordability, while managing risk at acceptable levels? In FY00, it was determined that a certain weapon refurbishment program could not be accomplished without the use of COTS components. The elements driving the use of COTS components included decreased cost, greater availability, and shorter delivery time. Key factors that required implementation included identifying the best suppliers and components, defining life cycles and predictions of obsolescence, testing the feasibility of using COTS components with a test contractor to ensure capability, as well as quality and reliability, and implementing the data management tools required to disseminate, store, track procurement, and qualify vendors. The primary effort of this project then was to concentrate on the risks involved in the use of COTS and address the issues of part and vendor selection, procurement and acceptance processes, and qualification of the parts via part and sample testing. The Enterprise Component Information System (eCIS) was used to manage the information generated by the COTS process. eCIS is a common interface for both the design and production of NWC components and systems integrating information between SNL National Laboratory (SNL) and the Kansas City Plant (KCP). The implementation of COTS components utilizes eCIS from part selection through qualification release. All part related data is linked across an unclassified network for access by both SNL and KCP personnel. The system includes not only NWC part information but also includes technical reference data for over 25 Million electronic and electromechanical commercial and military parts via a data subscription. With the capabilities added to the system through this project, eCIS provides decision support, parts list/BOM analysis, editing, tracking, workflows, reporting, and history/legacy information integrating manufacturer reference, company technical, company business, and design data.

Long-term Statistics of Continental Cumuli: Does Aerosol Trigger Cumulus Variability?  

Science Conference Proceedings (OSTI)

Atmospheric aerosols may control the formation, maintenance, and dissipation of cumuli by changing their microphysics. Recent observational and modeling results exist both in support and against strong potential impacts of aerosol [1-3]. Typically, the aerosol impact on water clouds has been investigated for regions with high aerosol loading and/or large atmospheric moisture [4]. Can we provide observational evidence of the aerosol-cloud relationship for a relatively dry continental region with low/moderate aerosol burden? To address this question, we revisit the aerosol-cloud relationship at the Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) Southern Great Plains (SGP) site. In comparison with highly polluted regions, the SGP site is characterized by relatively small-to-moderate aerosol loading. Also, moisture content is small-to-moderate (compared to marine and coastal regions) for the SGP site. Because cumulus clouds have important impacts on climate forcing estimations [5] and are susceptible to aerosol effects [6], we focus on fair-weather cumuli (FWC) and their association with aerosol concentration and other potentially important factors. This association is investigated using a new 8-year aerosol and cloud climatology (2000-2007) developed with collocated and coincident surface and satellite observations.

Workshop on core and sample curation for the National Continental Scientific Drilling Program  

DOE Green Energy (OSTI)

The Workshop on Core and Sample Curation was held to discuss the best means of handling, distributing, and advertising samples and data collected during a Continental Scientific Drilling Program (CSDP) and to establish better communication between sample curators regarding common problems. It was geneerally agreed that CSDP samples should be handled, on a regional basis, by existing data systems and sample repositories judged to have adequate staff and support. Repository design, sample handling procedures, and sample accounting systems were discussed. Across North America, support for curation of geological samples was varied, but it was strongest within states or regions with well-established energy and mineral industries. A well-supported repository pays for itself through the circulation and preservation of samples and stratigraphic information. A national CSDP must have a well-established curatorial policy and system of regional repositories to circulate information and samples throughout the scientific community. Well-curated samples and data are a national resource with considerable benefits for industry and academia. Attendees agreed to form a Society of Geoscience Curators to maintain communication between curators from private, government, and university repositories and core research laboratories.

The effect of LNG on the relationship between UK and Continental European natural gas markets  

E-Print Network (OSTI)

The long-term relationship between the prices of natural gas in the United Kingdom and oil-indexed natural gas in the North West European market is the result of seasonal arbitrage. This paper empirically investigates this long-term relationship and offers two main contributions: (i) To the best knowledge of the author, this is the first study to take into account important UK spot gas market drivers such as seasonality, temperature and gas storage injection/withdrawal behaviour when examining the structural relationship between UK and Continental European markets. (ii) The effect of UK import capacity extensions since 2005, through both pipeline and LNG regasifcation capacity, on this longterm relationship will be analyzed. The results suggest that there is a signifcant structural break in 2006 when the two markets decouple and move from an old to a new, much weaker, long-term relationship. From the end of 2008 onwards, the time at which UK LNG imports started to increase, this long-term relationship appears to break down altogether.

Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Authors: C.J. Rawn, R. Sassen, S.M. Ulrich, E.A. Payzant, B.C. Chakoumakos, and T.J. Phelps Venue: 6th International Conference on Gas Hydrates, Fairmont Hotel, Vancouver, Canada July 6-10, 2008. http://www.icgh.org/ [external site]. Abstract: Clathrate hydrates of methane and other small alkanes occur widespread as terrestrial components in marine sediments of the continental margins and in permafrost sediments of the arctic. Quantitative study of natural clathrate hydrates is hampered by the difficulty in obtaining pristine samples, particularly from submarine environments. Bringing samples of clathrate hydrate from the seafloor at depths without compromising their integrity is not trivial. Most physical property measurements are based on studies of laboratory-synthesized samples. Here we report x-ray powder diffraction measurements of a natural gas hydrate sample from the Green Canyon, Gulf of Mexico (GOM). The first data were collected in 2002 and revealed ice and structure II gas hydrate. In the subsequent time the sample has been stored in liquid nitrogen. Recently new x-ray powder diffraction data have been collected as a function of temperature. Rietveld refinements on this new data show that there is approximately 50 wt % gas hydrate with structure type II and 50% ice at -140, -130, -115, -100, and -85oC. The Rietveld refinements on the data sets collected at -70 and -55oC show the amount of structure type II hydrate decreasing to approximately 40% and 37%, respectively. The Rietveld refinement of the data set collected at -40oC shows a sharp decrease in the amount of structure type II hydrate to approximately 9%. Rietveld refinements on the data sets collected at -25 and -10oC indicated that the structure type II hydrate is still present at 7 and 3%, respectively

Assssment and Mapping of the Riverine Hydrokinetic Resource in the Continental United States  

DOE Green Energy (OSTI)

Segment-specific theoretical resource was aggregated by major hydrologic region in the contiguous, lower 48 states and totaled 1,146 TWh/yr. The aggregate estimate of the Alaska theoretical resource is 235 TWh/yr, yielding a total theoretical resource estimate of 1,381 TWh/yr for the continental US. The technically recoverable resource in the contiguous 48 states was estimated by applying a recovery factor to the segment-specific theoretical resource estimates. The recovery factor scales the theoretical resource for a given segment to take into account assumptions such as minimum required water velocity and depth during low flow conditions, maximum device packing density, device efficiency, and flow statistics (e.g., the 5 percentile flow relative to the average flow rate). The recovery factor also takes account of ?back effects? ? feedback effects of turbine presence on hydraulic head and velocity. The recovery factor was determined over a range of flow rates and slopes using the hydraulic model, HEC-RAS. In the hydraulic modeling, presence of turbines was accounted for by adjusting the Manning coefficient. This analysis, which included 32 scenarios, led to an empirical function relating recovery factor to slope and discharge. Sixty-nine percent of NHDPlus segments included in the theoretical resource estimate for the contiguous 48 states had an estimated recovery factor of zero. For Alaska, data on river slope was not readily available; hence, the recovery factor was estimated based on the flow rate alone. Segment-specific estimates of the theoretical resource were multiplied by the corresponding recovery factor to estimate

APPLICATION OF RESERVOIR CHARACTERIZATION AND ADVANCED TECHNOLOGY TO IMPROVE RECOVERY AND ECONOMICS IN A LOWER QUALITY SHALLOW SHELF SANANDRES RESERVOIR  

Science Conference Proceedings (OSTI)

The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three-dimensional (3-D) seismic; (3) Crosswell bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO{sub 2}) stimulation treatments; (6) Hydraulic fracturing design and monitoring; (7) Mobility control agents.

Depositional sequences and integrated recovery efficiency forecast models for San Andres and Clearfork Units in the Central Basin Platform and the Northern Shelf, west Texas  

E-Print Network (OSTI)

This paper develops depositional sequences of the carbonate ramp and the carbonate shelf models for an idealized cycle and multiple cycles of depositions. Based on the developed depositional sequences, the integrated recovery efficiency forecast models of primary, initial waterflood and infill drilling are developed for the San Andres and Clearfork reservoirs in Central Basin Platform and the Northern Shelf, west Texas. The geological parameters and well spacing are considered major factors for controlling recovery efficiencies. The depositional environment and diagenesis are controlling geological factors affecting oil recovery efficiencies. The depositional sequences characterize the vertical and lateral variations of depositional-energy environments in development of the carbonate ramp and the carbonate shelf The depositional-energy environment controls the depositional rock's facies. The well-sorted and large-size grainstones are related to the higher depositional-energy environment. The poorly-sorted and small-size rocks are related to the lower depositional-energy environment. The depositions of the San Andres and Clearfork formation in the Central Basin Platform, separately, follow the prograding-ramp sequences of one major cycle with multiple subcycles. The lumping depositional energy increases from the inner platform to the platform boundary. Similarly, the depositions of San Andres and Clearfork formation in the Northern Shelf also follow one major prograding cycle with multiple subcycles, separately. However, the lumping depositional energy, decreases from the inner platform to the platform boundary. A normalized depositional energy index is defined based on the depositional sequences of the ramp and shelf models. Normalization is also used to define a porosity index and a well spacing index. Linear and exponential regressions on a database are conducted to develop recovery efficiency forecast models which include depositional energy, porosity and well spacing indices. Section 17, Dollarhide Clearfork Unit is used as an example to show the applications of the recovery efficiency forecast models.

Canada-USA Salmon Shelf Survival Study, 2007-2008 Annual Report.  

DOE Green Energy (OSTI)

Historically, salmon stocks from the Columbia River and Snake River formed one of the most valuable fisheries on the west coast of North America. However, salmon and steelhead returns sharply declined during the 1980s and 1990s to reach nearly 1 million fish. Although several factors may be responsible for the decline of Columbia River salmon and steelhead, there is increasing evidence that these drastic declines were primarily attributable to persistently unfavorable ocean conditions. Hence, an understanding of the effects of ocean conditions on salmon production is required to forecast the return of salmon to the Columbia River basin and to assess the efficacy of mitigation measures such as flow regulation on salmon resources in this system. The Canadian Program on High Seas Salmon has been collecting juvenile salmon and oceanographic data off the west coast of British Columbia and Southeast Alaska since 1998 to assess the effects of ocean conditions on the distribution, migration, growth, and survival of Pacific salmon. Here, we present a summary of the work conducted as part of the Canada-USA Salmon Shelf Survival Study during the 2008 fiscal year and compare these results with those obtained from previous years. The working hypothesis of this research is that fast growth enhances the marine survival of salmon, either because fast growing fish quickly reach a size that is sufficient to successfully avoid predators, or because they accumulate enough energy reserves to better survive their first winter at sea, a period generally considered critical in the life cycle of salmon. Sea surface temperature decreased from FY05 to FY08, whereas, the summer biomass of phytoplankton increased steadily off the west coast of Vancouver Island from FY05 to FY08. As in FY07, zooplankton biomass was generally above average off the west coast of Vancouver Island in FY08. Interestingly, phytoplankton and zooplankton biomass were higher in FY08 than was expected from the observed nutrient concentration that year. This suggests nutrients were more effectively by phytoplankton in FY08. In addition, the abundance of lipid-rich northern copepods increased from FY05 to FY08, whereas lipid-poor southern copepods showed the opposite pattern, suggesting that growth conditions were more favorable to juvenile salmon in FY08 than in previous years. However, growth indices for juvenile coho salmon were near the 1998-2008 average, both off the west coast of Vancouver Island and Southeast Alaska, indicating that additional factors beside prey quality affect juvenile salmon growth in the marine environment. Catches of juvenile Chinook, sockeye and chum salmon off the west coast of Vancouver Island in June-July 2008 were the highest on record during summer since 1998, suggesting that early marine survival for the 2008 smolt year was high. Interestingly, the proportion of hatchery fish was high (80-100%) among the juvenile Columbia River Chinook salmon caught off the British Columbia coast during summer, suggest that relatively few wild Chinook salmon are produced in the Columbia River Chinook. In addition, we also recovered two coded-wire tagged juvenile Redfish Lake sockeye salmon in June 2008 off the west coast of British Columbia. As relatively few Redfish Lake sockeye smolts are tagged each year, this also suggests that early marine survival was high for these fish, and may result in a high return in 2009 if they mature at age three, or in 2010 if they mature at age four. To date, our research shows that different populations of Columbia River salmon move to different locations along the coastal zone where they establish their ocean feeding grounds and overwinter. We further show that ocean conditions experienced by juvenile Columbia River salmon vary among regions of the coast, with higher plankton productivity and temperatures off the west coast of Vancouver Island than in Southeast Alaska. Hence, different stocks of juvenile salmon originating from the Columbia River and Snake River are exposed to different ocean conditions and may respond differ

ARM - Midlatitude Continental Convective Clouds - Ultra High Sensitivity Aerosol Spectrometer(tomlinson-uhsas)  

DOE Data Explorer (OSTI)

Ultra High Sensitivity Aerosol Spectrometer (UHSASA) A major component of the Mid-latitude Continental Convective Clouds Experiment (MC3E) field campaign was the deployment of an enhanced radiosonde array designed to capture the vertical profile of atmospheric state variables (pressure, temperature, humidity wind speed and wind direction) for the purpose of deriving the large-scale forcing for use in modeling studies. The radiosonde array included six sites (enhanced Central Facility [CF-1] plus five new sites) launching radiosondes at 3-6 hour sampling intervals. The network will cover an area of approximately (300)2 km2 with five outer sounding launch sites and one central launch location. The five outer sounding launch sites are: S01 Pratt, KS [ 37.7oN, 98.75oW]; S02 Chanute, KS [37.674, 95.488]; S03 Vici, Oklahoma [36.071, -99.204]; S04 Morris, Oklahoma [35.687, -95.856]; and S05 Purcell, Oklahoma [34.985, -97.522]. Soundings from the SGP Central Facility during MC3E can be retrieved from the regular ARM archive. During routine MC3E operations 4 radiosondes were launched from each of these sites (approx. 0130, 0730, 1330 and 1930 UTC). On days that were forecast to be convective up to four additional launches were launched at each site (approx. 0430, 1030, 1630, 2230 UTC). There were a total of approximately 14 of these high frequency launch days over the course of the experiment. These files contain brightness temperatures observed at Purcell during MC3E. The measurements were made with a 5 channel (22.235, 23.035, 23.835, 26.235, 30.000GHz) microwave radiometer at one minute intervals. The results have been separated into daily files and the day of observations is indicated in the file name. All observations were zenith pointing. Included in the files are the time variables base_time and time_offset. These follow the ARM time conventions. Base_time is the number seconds since January 1, 1970 at 00:00:00 for the first data point of the file and time_offset is the offset in seconds from base_time.

Assssment and Mapping of the Riverine Hydrokinetic Resource in the Continental United States  

SciTech Connect

The U.S. Department of Energy (DOE) funded the Electric Power Research Institute and its collaborative partners, University of Alaska ? Anchorage, University of Alaska ? Fairbanks, and the National Renewable Energy Laboratory, to provide an assessment of the riverine hydrokinetic resource in the continental United States. The assessment benefited from input obtained during two workshops attended by individuals with relevant expertise and from a National Research Council panel commissioned by DOE to provide guidance to this and other concurrent, DOE-funded assessments of water based renewable energy. These sources of expertise provided valuable advice regarding data sources and assessment methodology. The assessment of the hydrokinetic resource in the 48 contiguous states is derived from spatially-explicit data contained in NHDPlus ?a GIS-based database containing river segment-specific information on discharge characteristics and channel slope. 71,398 river segments with mean annual flow greater than 1,000 cubic feet per second (cfs) mean discharge were included in the assessment. Segments with discharge less than 1,000 cfs were dropped from the assessment, as were river segments with hydroelectric dams. The results for the theoretical and technical resource in the 48 contiguous states were found to be relatively insensitive to the cutoff chosen. Raising the cutoff to 1,500 cfs had no effect on estimate of the technically recoverable resource, and the theoretical resource was reduced by 5.3%. The segment-specific theoretical resource was estimated from these data using the standard hydrological engineering equation that relates theoretical hydraulic power (Pth, Watts) to discharge (Q, m3 s-1) and hydraulic head or change in elevation (??, m) over the length of the segment, where ? is the specific weight of water (9800 N m-3): ??? = ? ? ?? For Alaska, which is not encompassed by NPDPlus, hydraulic head and discharge data were manually obtained from Idaho National Laboratory?s Virtual Hydropower Prospector, Google Earth, and U.S. Geological Survey gages. Data were manually obtained for the eleven largest rivers with average flow rates greater than 10,000 cfs and the resulting estimate of the theoretical resource was expanded to include rivers with discharge between 1,000 cfs and 10,000 cfs based upon the contribution of rivers in the latter flow class to the total estimate in the contiguous 48 states. Segment-specific theoretical resource was aggregated by major hydrologic region in the contiguous, lower 48 states and totaled 1,146 TWh/yr. The aggregate estimate of the Alaska theoretical resource is 235 TWh/yr, yielding a total theoretical resource estimate of 1,381 TWh/yr for the continental US. The technically recoverable resource in the contiguous 48 states was estimated by applying a recovery factor to the segment-specific theoretical resource estimates. The recovery factor scales the theoretical resource for a given segment to take into account assumptions such as minimum required water velocity and depth during low flow conditions, maximum device packing density, device efficiency, and flow statistics (e.g., the 5 percentile flow relative to the average flow rate). The recovery factor also takes account of ?back effects? ? feedback effects of turbine presence on hydraulic head and velocity. The recovery factor was determined over a range of flow rates and slopes using the hydraulic model, HEC-RAS. In the hydraulic modeling, presence of turbines was accounted for by adjusting the Manning coefficient. This analysis, which included 32 scenarios, led to an empirical function relating recovery factor to slope and discharge. Sixty-nine percent of NHDPlus segments included in the theoretical resource estimate for the contiguous 48 states had an estimated recovery factor of zero. For Alaska, data on river slope was not readily available; hence, the recovery factor was estimated based on the flow rate alone. Segment-specific estimates of the theoretical resource were multiplied by the corresponding recovery factor to estimate

Application of lactic acid in combination with melanosis inhibitors to improve shelf life of Texas brown shrimp (Penaeus aztecus)  

E-Print Network (OSTI)

The shelf life of fresh shrimp stored on ice is limited by two factors: melanosis (blackspot) and microbial spoilage. In this study L-lactic acid was tested, alone and in combination with sodium bisulfite and 4-hexylresorcinol, to determine their effectiveness as both melanosis and microbial spoilage inhibitors. Brown shrimp (Penaeus aztecus) were obtained from the Gulf of Mexico on board a commercial fishing vessel. Immediately after harvest, the shrimp were separated from the rest of the catch. The shrimp were then headed, washed, and sorted into six groups that were treated by dipping for I min in the following solutions: (1) Control (sea water), (2) 1.0% L-lactic acid, (3) 1.25% sodium bisulfite, (4) 0.0025% 4-hexylresorcinol, (5) 1.25% sodium bisulfite with 1.0% L-lactic acid, or (6) 0.0025% 4- hexylresorcinol with 1.0% L-lactic acid. Each of the six groups of shrimp was split into 2 subgroups. One subgroup of shrimp was treated immediately after sorting and the other subgroup was treated after a 2-hr delay on deck at ambient temperature to simulate normal practices during peak harvesting times. Each subgroup of shrimp was placed in a nylon mesh bag, completely submerged in the appropriate dip solution for 1 min with moderate up and down agitation, and drained. Each treatment group was stored on ice for 16 days in separate ice chests, and examined over the storage period for aerobic plate count (APC), pH, and degree of melanosis. Overall, this study demonstrated that treatment with L-lactic acid, alone or in combination with 4-hexylresorcinol, had no detectable effect on the microbiological shelf life of brown shrimp (Penaeus aztecus). In addition, 4-hexylresorcinol performed exceptionally well as a melanosis inhibitor, whether alone or in combination with L-lactic acid. However, extensive bacterial growth was demonstrated in the 4-hexylresorcinol dip solution during normal storage on deck, creating the potential for a heavy bacterial inoculation of shrimp during a typical dipping process. Addition of L-lactic acid to the 4-hexylresorcinol dip solution prevented bacterial growth in the dip solution and did not interfere with melanosis inhibition.

CO{sub 2} Huff-n-Puff process in a light oil shallow shelf carbonate reservoir  

SciTech Connect

The application of cyclic CO{sub 2}, often referred to as the CO{sub 2} Huff-n-Puff process, may find its niche in the maturing waterfloods of the Permian Basin. Coupling the CO{sub 2} H-n-P process to miscible flooding applications could provide the needed revenue to sufficiently mitigate near-term negative cash flow concerns in the capital intensive miscible projects. Texaco Exploration and Production Inc. and the US Department of Energy have teamed up in an attempt to develop the CO{sub 2} Huff-n-Puff process in the Grayburg and San Andres formations, a light oil, shallow shelf carbonate reservoir that exists throughout the Permian Basin. This cost-shared effort is intended to demonstrate the viability of this underutilized technology in a specific class of domestic reservoir. The selected site for this demonstration project is the Central Vacuum Unit waterflood in Lea County, New Mexico. The goals of the project are the development of guidelines for cost-effective selection of candidate reservoirs and wells, along with estimating recovery potential. This project has two defined budget periods. The first budget period primarily involves tasks associated with reservoir analysis and characterization, characterizing existing producibility problems, and reservoir simulation of the proposed technology. The final budget period covers the actual field demonstration of the proposed technology. Technology transfer spans the entire course of the project. This report covers the concluding tasks performed under the second budget period.

HETEROGENEOUS SHALLOW-SHELF CARBONATE BUILDUPS IN THE PARADOX BASIN, UTAH AND COLORADO: TARGETS FOR INCREASED OIL PRODUCTION AND RESERVES USING HORIZONTAL DRILLING TECHNIQUES  

Science Conference Proceedings (OSTI)

The Paradox Basin of Utah, Colorado, Arizona, and New Mexico contains nearly 100 small oil fields producing from carbonate buildups within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to 10 wells with primary production ranging from 700,000 to 2,000,000 barrels (111,300-318,000 m{sup 3}) of oil per field and a 15 to 20 percent recovery rate. At least 200 million barrels (31.8 million m{sup 3}) of oil will not be recovered from these small fields because of inefficient recovery practices and undrained heterogeneous reservoirs. Several fields in southeastern Utah and southwestern Colorado are being evaluated as candidates for horizontal drilling and enhanced oil recovery from existing vertical wells based upon geological characterization and reservoir modeling case studies. Geological characterization on a local scale is focused on reservoir heterogeneity, quality, and lateral continuity, as well as possible reservoir compartmentalization, within these fields. This study utilizes representative cores, geophysical logs, and thin sections to characterize and grade each field's potential for drilling horizontal laterals from existing development wells. The results of these studies can be applied to similar fields elsewhere in the Paradox Basin and the Rocky Mountain region, the Michigan and Illinois Basins, and the Midcontinent region. This report covers research activities for the second half of the third project year (October 6, 2002, through April 5, 2003). The primary work included describing and mapping regional facies of the upper Ismay and lower Desert Creek zones of the Paradox Formation in the Blanding sub-basin, Utah. Regional cross sections show the development of ''clean carbonate'' packages that contain all of the productive reservoir facies. These clean carbonates abruptly change laterally into thick anhydrite packages that filled several small intra-shelf basins in the upper Ismay zone. Examination of upper Ismay cores identified seven depositional facies: open marine, middle shelf, inner shelf/tidal flat, bryozoan mounds, phylloid-algal mounds, quartz sand dunes, and anhydritic salinas. Lower Desert Creek facies include open marine, middle shelf, protomounds/collapse breccia, and phylloid-algal mounds. Mapping the upper Ismay zone facies delineates very prospective reservoir trends that contain porous, productive buildups around the anhydrite-filled intra-shelf basins. Facies and reservoir controls imposed by the anhydritic intra-shelf basins should be considered when selecting the optimal location and orientation of any horizontal drilling from known phylloidalgal reservoirs to undrained reserves, as well as identifying new exploration trends. Although intra-shelf basins are not present in the lower Desert Creek zone of the Blanding sub-basin, drilling horizontally along linear shoreline trends could also encounter previously undrilled, porous intervals and buildups. Technology transfer activities consisted of a technical presentation at a Class II Review conference sponsored by the National Energy Technology Laboratory at the Center for Energy and Economic Diversification in Odessa, Texas. The project home page was updated on the Utah Geological Survey Internet web site.

Evaluating the Influence of Pore Architecture and Initial Saturation on Wettability and Relative Permeability in Heterogeneous, Shallow-Shelf Carbonates  

Science Conference Proceedings (OSTI)

Thin (3-40 ft thick), heterogeneous, limestone and dolomite reservoirs, deposited in shallow-shelf environments, represent a significant fraction of the reservoirs in the U.S. midcontinent and worldwide. In Kansas, reservoirs of the Arbuckle, Mississippian, and Lansing-Kansas City formations account for over 73% of the 6.3 BBO cumulative oil produced over the last century. For these reservoirs basic petrophysical properties (e.g., porosity, absolute permeability, capillary pressure, residual oil saturation to waterflood, resistivity, and relative permeability) vary significantly horizontally, vertically, and with scale of measurement. Many of these reservoirs produce from structures of less than 30-60 ft, and being located in the capillary pressure transition zone, exhibit vertically variable initial saturations and relative permeability properties. Rather than being simpler to model because of their small size, these reservoirs challenge characterization and simulation methodology and illustrate issues that are less apparent in larger reservoirs where transition zone effects are minor and most of the reservoir is at saturations near S{sub wirr}. These issues are further augmented by the presence of variable moldic porosity and possible intermediate to mixed wettability and the influence of these on capillary pressure and relative permeability. Understanding how capillary-pressure properties change with rock lithology and, in turn, within transition zones, and how relative permeability and residual oil saturation to waterflood change through the transition zone is critical to successful reservoir management and as advanced waterflood and improved and enhanced recovery methods are planned and implemented. Major aspects of the proposed study involve a series of tasks to measure data to reveal the nature of how wettability and drainage and imbibition oil-water relative permeability change with pore architecture and initial water saturation. Focus is placed on carbonate reservoirs of widely varying moldic pore systems that represent the major of reservoirs in Kansas and are important nationally and worldwide. A goal of the project is to measure wettability, using representative oils from Kansas fields, on a wide range of moldic-porosity lithofacies that are representative of Kansas and midcontinent shallow-shelf carbonate reservoirs. This investigation will discern the relative influence of wetting and pore architecture. In the midcontinent, reservoir water saturations are frequently greater than 'irreducible' because many reservoirs are largely in the capillary transition zone. This can change the imbibition oil-water relative permeability relations. Ignoring wettability and transition-zone relative permeabilities in reservoir modeling can lead to over- and under-prediction of oil recovery and recovery rates, and less effective improved recovery management. A goal of this project is to measure drainage and imbibition oil-water relative permeabilities for a large representative range of lithofacies at differ ent initial water saturations to obtain relations that can be applied everywhere in the reservoir. The practical importance of these relative permeability and wettability models will be demonstrated by using reservoir simulation studies on theoretical/generic and actual reservoir architectures. The project further seeks to evaluate how input of these new models affects reservoir simulation results at varying scales. A principal goal is to obtain data that will allow us to create models that will show how to accurately simulate flow in the shallow-structure, complex carbonate reservoirs that lie in the transition zone. Tasks involved to meet the project objectives include collection and consolidation of available data into a publicly accessible relational digital database and collection of oil and rock samples from carbonate fields around the state (Task 1). Basic properties of these rocks and oils will be measured and used in wettability tests. Comparison will be performed between crude and synthetic oil wettability and

Application of Reservoir Characterization and Advanced Technology to Improve Recovery and Economics in a Lower Quality Shallow Shelf Carbonate Reservoir  

SciTech Connect

The OXY-operated Class 2 Project at West Welch is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO{sub 2} flood design based on the reservoir characterization. Although Budget Period 1 for the Project officially ended 12/31/96, reservoir characterization and simulation work continued during the Budget Period 2. During the fifth and sixth annual reporting periods (8/3/98-8/2/00) covered by this report, work continued on interpretation of the cross well seismic data to create porosity and permeability profiles which were distributed into the reservoir geostatistically. The initial interwell seismic CO{sub 2} monitor survey was conducted, the acquired data processed and interpretation started. Only limited well work and facility construction was conducted in the project area. The CO{sub 2} injection initiated in October 1997 was continued, although the operator had to modify the operating plan in response to low injection rates, well performance and changes in CO{sub 2} supply. CO{sub 2} injection was focused in a smaller area to increase the reservoir processing rate. By the end of the reporting period three producers had shown sustained oil rate increases and ten wells had experienced gas (CO{sub 2}) breakthrough.

CO{sub 2} Huff-n-Puff process in a light oil shallow shelf carbonate reservoir. 1994 Annual report  

SciTech Connect

It is anticipated that this project will show that the application of the CO{sub 2} Huff-n-Puff process in shallow shelf carbonates can be economically implemented to recover appreciable volumes of light oil. The goals of the project are the development of guidelines for cost-effective selection of candidate reservoirs and wells, along with estimating recovery potential. The selected site for the demonstration project is the Central Vacuum Unit waterflood in Lea County, New Mexico. Work is nearing completion on the reservoir characterization components of the project. The near-term emphasis is to, (1) provide an accurate distribution of original oil-in-place on a waterflood pattern entity level, (2) evaluate past recovery efficiencies, (3) perform parametric simulations, and (4) forecast performance for a site specific field demonstration of the proposed technology. Macro zonation now exists throughout the study area and cross-sections are available. The Oil-Water Contact has been defined. Laboratory capillary pressure data was used to define the initial water saturations within the pay horizon. The reservoir`s porosity distribution has been enhanced with the assistance of geostatistical software. Three-Dimensional kriging created the spatial distributions of porosity at interwell locations. Artificial intelligence software was utilized to relate core permeability to core porosity, which in turn was applied to the 3-D geostatistical porosity gridding. An Equation-of-State has been developed and refined for upcoming compositional simulation exercises. Options for local grid-refinement in the model are under consideration. These tasks will be completed by mid-1995, prior to initiating the field demonstrations in the second budget period.

Effect of electron beam irradiation on quality and shelf-life of Tommy Atkins mango (Mangifera indica l.) and blueberry (Vaccinium corymbsum l.)  

E-Print Network (OSTI)

The main goal of this research was to determine the feasibility of using electron beam irradiation as an alternative disinfestation technology while preserving the overall quality of mangoes, and to verify its suitability for the preservation shelf life of blueberries. Physicochemical and sensory characteristics of the fruits were evaluated. Mangoes were irradiated at 1.0, 1.5 and 3.1 kGy using a 10MeV (10 kW) linear accelerator (LINAC) with double beam fixture. Samples were stored at 12�ºC and 62.7% RH for 21 days. Blueberries packed in plastic clamshell containers were irradiated at 1.1, 1.6 and 3.2 kGy doses using the same linear accelerator with a single beam. The shelf life of the berries stored at 5�ºC and 70.4% RH was evaluated for 14 days. The firmness of mangoes irradiated at 1.5 and 3.1 kGy significantly (p > 0.05) decreased during storage. There was a reduction of total sugars (8.1% and 14.1%) in samples irradiated at 1.0 kGy and 1.5 kGy, respectively. All irradiated mangoes had significantly lower (50- 70 %) ascorbic acid content throughout storage. The phenolic compounds increased in samples irradiated at 1.5 kGy (27.4%) and 3.1 kGy) (18.3%). Sensory evaluation of the fruits irradiated with 3.1 kGy showed significantly less acceptability for overall quality, color, texture and aroma. Irradiation of blueberries at 1.1 kGy had no significant (p > 0.05) effect on the fruits' physicochemical characteristics with the exception of ascorbic acid which decreased by 17% after 14 days. A significant decrease in texture (firmness) of irradiated berries was observed during storage time. Total sugars decreased in all irradiated fruits while total phenolics and tannins increased (10 -20%). Sensory attributes of samples irradiated with 1.1 kGy and 1.6 kGy were found acceptable by the panelists. The high dose-treated fruits were considered unacceptable. The results from this research suggest that a 1.5 kGy is the best treatment to maintain the quality attributes of mangoes and increase the shelf life by three days. The electron beam irradiation of packed blueberries at doses of 1.1 and 1.6 kGy ensures and enhances the quality and the shelf life of blueberries up to 14 days.

Evaluation of a Deep Plan Office Space Daylit with an Optical Light Pipe and a Specular Light Shelf  

E-Print Network (OSTI)

This research developed the Optical Light Pipe (OLP) as a feasible solution to solve the problem of insufficient daylighting in deep plan office spaces for predominantly sunny climates. It further combined the OLP with a Specular Light Shelf (SLS) to achieve uniform daylighting. This research was performed with an experimental setup of two 1:4 scale models of deep plan office spaces, modified from an earlier research on optical light pipe at College Station, TX. Blinds and shading devices were installed on the south façade to provide daylight to the front zone of a 20 feet by 30 feet office module. The back zone was daylit by the OLP hidden in the plenum. The existing OLP design was optimized through computer aided ray-tracing. The SLS design was based on an earlier prototype designed at Lawrence Berkeley National Labs (LBNL). Results were based on observations made on clear and cloudy sky days between February 3rd and March 17th. The OLP achieved more than 300 lux of average workplane illuminance for 7.4 hours, when global horizontal illuminance was greater than 40,000 lux. It also achieved 200 lux of illuminance higher than an earlier prototype (Martins-Mogo, 2005) on workplane between 1000hrs and 1630hrs. It exhibited a glare free daylight distribution with luminance ratios well within prescribed limits on most of the vertical surfaces, with a relatively uniform illuminance distribution on back taskplane. OLP was better than windows with blinds and shading at providing diffuse daylight in backzone on a cloudy day, when global horizontal illuminance was greater than 20,000 lux. The OLP used in combination with SLS achieved more than 500 lux of average workplane illuminance for 6 hours, when global horizontal illuminance was greater than 40,000 lux. SLS also produced more uniform illuminance levels on the workplane at all times and on the leftwall at most times. However, it produced non-uniform luminance distribution on walls and ceiling and luminance ratios higher than allowable limits on the sidewall for some morning hours, and hence needed further refinement in design.

Limitations of ad hoc "SKA+VLBI" configurations & the need to extend SKA to trans-continental dimensions  

E-Print Network (OSTI)

The angular resolution of the proposed Square Kilometre Array, SKA, must be extended towards the milliarcsecond scale if it is to resolve the distant starburst galaxies that are likely to dominate the radio source counts at micro and sub-microJy flux levels. This paper considers the best way of extending SKA's angular resolution towards the milliarcsecond scale. Two possible SKA-VLBI configurations have been investigated and simulated SKA and SKA-VLBI visibility data sets generated. The effects of non-uniform data weighting on the associated images are considered. The results suggest that the preferred option is for SKA to be extended to trans-continental dimensions. By retaining 50% of the array's collecting area within a region no larger than 50 km, the surface brightness sensitivity of the array at arcsec resolution is hardly compromised. In this configuration SKA's capabilities are impressive: in a single 12 hour run, between 100-1000 sources will be simultaneously detected and imaged with arcsecond, sub-arcsecond and milliarcsecond resolution.

The impact of climate and CO{sub 2} changes on ecosystem dynamics of the continental United States  

Science Conference Proceedings (OSTI)

The VEMAP study used three biogeochemical (BGC) models to investigate the impact of changes in climate and CO{sub 2} concentrations over the continental US. These models were Biome-BGC, CENTURY, and TEM. Differences among the BGC models and the climate scenarios (three different GCM-derived 2xCO{sub 2} climates were used) contributed equally to the variation in estimates of C dynamics under changing climate and CO,. The response of the individual biogeochemical models to increases in temperature and tp water stress are largely responsible for their behavior under climate change. All three models generally predict increases in C uptake when increases in temperature are not vastly greater than increases in precipitation, such as seen in the GFDL scenario. Differences in the biotic response to elevated CO{sub 2} determined the overall response of NPP and total system C storage due to differences on the manner in which plant C/N, transpiration, and photosynthesis are modified by the three different BGC models.

ARM - Midlatitude Continental Convective Clouds Experiment (MC3E): Multi-Frequency Profilers, Surface Meteorology (williams-surfmet)  

DOE Data Explorer (OSTI)

This data was collected by the NOAA 449-MHz and 2.8-GHz profilers in support of the Department of Energy (DOE) and NASA sponsored Mid-latitude Continental Convective Cloud Experiment (MC3E). The profiling radars were deployed in Northern Oklahoma at the DOE Atmospheric Radiation Mission (ARM) Southern Great Plans (SGP) Central Facility from 22 April through 6 June 2011. NOAA deployed three instruments: a Parsivel disdrometer, a 2.8-GHz profiler, and a 449-MHz profiler. The parasivel provided surface estimates of the raindrop size distribution and is the reference used to absolutely calibrate the 2.8 GHz profiler. The 2.8-GHz profiler provided unattenuated reflectivity profiles of the precipitation. The 449-MHz profiler provided estimates of the vertical air motion during precipitation from near the surface to just below the freezing level. By using the combination of 2.8-GHz and 449-MHz profiler observations, vertical profiles of raindrop size distributions can be retrieved. The profilers are often reference by their frequency band: the 2.8-GHz profiler operates in the S-band and the 449-MHz profiler operates in the UHF band. The raw observations are available as well as calibrated spectra and moments. This document describes how the instruments were deployed, how the data was collected, and the format of the archived data.

Relationships of Light Transmission, Stratification and Fluorescence in the Hypoxic Region of the Texas-Louisiana Shelf in Spring/Summer 2009  

E-Print Network (OSTI)

The growth of phytoplankton in hypoxic waters requires nutrients and light. In river plumes of the coastal ocean, river borne surface nutrient concentrations decrease with distance from the river mouth. Light availability at the surface also changes with distance from the river source, as particulates and other materials sink through the water column. Using in situ CTD sensors, water samples of nutrients, and ship flow-through data from two Louisiana Shelf research cruises, April and July 2009, the relationship between transmissivity, photosynthetically available radiation (PAR), stratification, and fluorescence are analyzed. PAR is measured using a silicon photovoltaic detector and is measured in the 400 to 700 nm range. A fluorometer is used to measure the fluorescence of chlorophyll a in g/L and is a proxy indicator for phytoplankton biomass. The Louisiana Shelf is home to the largest hypoxic zone in the western hemisphere, covering on average more than 15000 sq. km. The Louisiana hypoxic zone occurs seasonally in summer and is typically dissipated by physical processes in fall. Hypoxia is defined as waters that have a dissolved oxygen concentration of 1.4 ml/L and is the level at which marine organisms are typically adversely affected. Preliminary results show expected relationships between transmissivity and fluorescence in the water column indicating a positive correlation between light availability and fluorescence. The spatial distribution of stratification, light availability, fluorescence, and nutrients are compared for the different seasons.

CO{sub 2} Huff-n-Puff process in a light oil shallow shelf carbonate reservoir. Quarterly technical progress report, Fourth quarter 1995  

Science Conference Proceedings (OSTI)

The principle objective of the Central Vacuum Unit (CVU) CO{sub 2} Huff-n-Puff (H-n-P) project is to determine the feasibility and practicality of the technology in a waterflooded shallow shelf carbonate environment. The results of parametric simulation of the CO{sub 2} H-n-P process, coupled with the CVU reservoir characterization components will determine if this process is technically and economically feasible for field implementation. The technology transfer objective of the project is to disseminate the knowledge gained through an innovative plan in support of the Department of Energy`s objective of increasing domestic oil production and deferring the abandonment of shallow shelf carbonate (SSC) reservoirs. Texaco Exploration and Production Inc`s. (TEPI) mid-term plans are to implement a full-scale miscible CO{sub 2} project in the CVU. TEPI has concluded all of the Tasks associated with the First Budget Period. The DOE approved the TEPI continuation application. Budget Period No. 2 is now in progress. Initial injection of CO{sub 2} began in November, and after a short shut-in period for the soak, the well was returned to production in late December, 1995.

CO2 Huff-n-Puff process in a light oil shallow shelf carbonate reservoir. Annual report, January 1, 1995--December 31, 1995  

SciTech Connect

The application of cyclic CO{sub 2}, often referred to as the CO{sub 2} Huff-n-Puff process, may find its niche in the maturing waterfloods of the Permian Basin. Coupling the CO{sub 2} H-n-P process to miscible flooding applications could provide the needed revenue to sufficiently mitigate near-term negative cash flow concerns in the capital intensive miscible projects. Texaco Exploration & Production Inc. and the U.S. Department of Energy have teamed up in an attempt to develop the CO{sub 2} Huff-n-Puff process in the Grayburg/San Andres formation; a light oil, shallow shelf carbonate reservoir within the Permian Basin. This cost-shared effort is intended to demonstrate the viability of this underutilized technology in a specific class of domestic reservoir. A significant amount of oil reserves are located in carbonate reservoirs. Specifically, the carbonates deposited in shallow shelf (SSC) environments make up the largest percentage of known reservoirs within the Permian Basin of North America. Many of these known resources have been under waterflooding operations for decades and are at risk of abandonment if crude oil recoveries cannot be economically enhanced. The selected site for this demonstration project is the Central Vacuum Unit waterflood in Lea County, New Mexico.

Using Recent Advances in 2D Seismic Technology and Surface Geochemistry to Economically Redevelop a Shallow Shelf Carbonate Reservoir: Vernon Field, Isabella County, M, Class III  

SciTech Connect

In this project a consortium consisting of Cronus Exploration (Traverse City, MI), Michigan Technological University (Houghton, MI) and Western Michigan University (Kalamazoo, MI) proposed to develop and execute an economical and environmentally sensitive plan for recovery of hydrocarbons from an abandoned shallow-shelf carbonate field that is typical of many fields in the U.S. Midwest. This is a 5-year project that will use surface geochemistry as a tool to reduce risk in locating and producing hydrocarbons in Class II fields. The project will develop new techniques for measuring hydrocarbon gases in the soil horizon to locate new and bypassed oil in the shallow-shelf carbonate environments typified by the Dundee and Trenton Formations of the Michigan Basin (Fisher et. al., 1988). In Phase I of the project, the consortium proposes to re-develop the Vernon Oil field located in Vernon Twp, Isabella County, Michigan and produce both bypassed hydrocarbons from the original field and to locate and produce extensions of the original field.

Science Conference Proceedings (OSTI)

The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three-dimensional (3-D) seismic; (3) Crosswell bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO{sub 2}) stimulation treatments; (6) Hydraulic fracturing design and monitoring; and (7) Mobility control agents.

Environmental sampling and mud sampling program of CSDP (Continental Scientific Drilling Program) core hole VC-2B, Valles Caldera, New Mexico  

DOE Green Energy (OSTI)

An environmental sampling and drilling mud sampling program was conducted during the drilling operations of Continental Scientific Drilling Program (CSDP) core hole VC-2B, Valles caldera, New Mexico. A suite of four springs and creeks in the Sulphur Springs area were monitored on a regular basis to ensure that the VC-2B drilling program was having no environmental impact on water quality. In addition, a regional survey of springs in and around the Jemez Mountains was conducted to provide background data for the environmental monitoring. A drilling mud monitoring program was conducted during the operations to help identify major fluid entries in the core hole. 32 refs., 14 figs., 7 tabs.

The responses of net primary production (NPP) and total carbon storage for the continental United States to changes in atmospheric CO{sub 2}, climate, and vegetation  

Science Conference Proceedings (OSTI)

We extrapolated 3 biogeochemistry models (BIOME-BGC, CENTURY, and TEM) across the continental US with the vegetation distributions of 3 biogeography models (BIOME2, DOLY, and MAPSS) for contemporary climate at 355 ppmv CO{sub 2} and each of 3 GCM climate scenarios at 710 ppmv. For contemporary conditions, continental NPP ranges from 3132 to 3854 TgC/yr and total carbon storage ranges from 109 to 125 PgC. The responses of NPP range from no response (BIOME-BGC with DOLY or MAPSS vegetations for UKMO climate) to increases of 53% and 56% (TEM with BIOME2 vegetations for GFDL and OSU climates). The responses of total carbon storage vary from a decrease of 39% (BIOME-BGC with MAPSS vegetation for UKMO climate) to increases of 52% and 56% (TEM with BIOME2 vegetations for OSU and GFDL climates). The UKMO responses of BIOME-BGC with MAPSS vegetation are caused by both decreased forest area (from 44% to 38%) and photosynthetic water stress. The OSU and GFDL responses of TEM with BIOME2 vegetations are caused by forest expansion (from 46% to 67% for OSU and to 75% for GFDL) and increased nitrogen cycling.

Heat Flow and Gas Hydrates on the Continental Margin of India: Building on Results from NGHP Expedition 01  

SciTech Connect

The Indian National Gas Hydrate Program (NGHP) Expedition 01 presented the unique opportunity to constrain regional heat flow derived from seismic observations by using drilling data in three regions on the continental margin of India. The seismic bottom simulating reflection (BSR) is a well-documented feature in hydrate bearing sediments, and can serve as a proxy for apparent heat flow if data are available to estimate acoustic velocity and density in water and sediments, thermal conductivity, and seafloor temperature. Direct observations of temperature at depth and physical properties of the sediment obtained from drilling can be used to calibrate the seismic observations, decreasing the uncertainty of the seismically-derived estimates. Anomalies in apparent heat flow can result from a variety of sources, including sedimentation, erosion, topographic refraction and fluid flow. We constructed apparent heat flow maps for portions of the Krishna-Godavari (K-G) basin, the Mahanadi basin, and the Andaman basin and modeled anomalies using 1-D conductive thermal models. Apparent heat flow values in the Krishna-Godavari (K-G) basin and Mahanadi basin are generally 0.035 to 0.055 watts per square meter (W/m2). The borehole data show an increase in apparent heat flow as water depth increases from 900 to 1500 m. In the SW part of the seismic grid, 1D modeling of the effect of sedimentation on heat flow shows that ~50% of the observed increase in apparent heat flow with increasing water depth can be attributed to trapping of sediments behind a "toe-thrust" ridge that is forming along the seaward edge of a thick, rapidly accumulating deltaic sediment pile. The remainder of the anomaly can be explained either by a decrease in thermal conductivity of the sediments filling the slope basin or by lateral advection of heat through fluid flow along stratigraphic horizons within the basin and through flexural faults in the crest of the anticline. Such flow probably plays a role in bringing methane into the ridge formed by the toe-thrust. Because of the small anomaly due to this process and the uncertainty in thermal conductivity, we did not model this process explicitly. In the NE part of the K-G basin seismic grid, a number of local heat flow lows and highs are observed, which can be attributed to topographic refraction and to local fluid flow along faults, respectively. No regional anomaly can be resolved. Because of lack of continuity between the K-G basin sites within the seismic grid and those ~70 km to the NE in water depths of 1200 to 1500 m, we do not speculate on the reason for higher heat flow at these depths. The Mahanadi basin results, while limited in geographic extent, are similar to those for the KG basin. The Andaman basin exhibits much lower apparent heat flow values, ranging from 0.015 to 0.025 W/m2. Heat flow here also appears to increase with increasing water depth. The very low heat flow here is among the lowest heat flow observed anywhere and gives rise to a very thick hydrate stability zone in the sediments. Through 1D models of sedimentation (with extremely high sedimentation rates as a proxy for tectonic thickening), we concluded that the very low heat flow can probably be attributed to the combined effects of high sedimentation rate, low thermal conductivity, tectonic thickening of sediments and the cooling effect of a subducting plate in a subduction zone forearc. Like for the K-G basin, much of the local variability can be attributed to topography. The regional increase in heat flow with water depth remains unexplained because the seismic grid available to us did not extend far enough to define the local tectonic setting of the slope basin controlling this observational pattern. The results are compared to results from other margins, both active and passive. While an increase in apparent heat flow with increasing water depth is widely observed, it is likely a result of different processes in different places. The very low heat flow due to sedimentation and tectonics in the Andaman basin is at the low end of glob

Comparison of acoustic impedance and time-amplitude analysis techniques for reservoir description of a Gulf of Mexico shelf edge Clastic Field  

SciTech Connect

Post-stack, time-amplitude techniques are routinely used in the estimation of reserves and the positioning of wells in low impedance, unconsolidated reservoir sands in the offshore Gulf of Mexico (Texas and Louisiana). Time amplitude analysis of 3D seismic data, when properly calibrated, can yield reliable estimates of net hydrocarbon pay, reservoir distribution, and volumetrics. Acoustic impedance (Al) analysis can also be used for such prospect appraisal and development work. However, the combined use of both techniques for reservoir description is not common. Some advantages in acoustic impedance (over amplitude analysis) are: (1) properly constrained Al traces better image the reservoir rock configuration (that is, they provide a more [open quotes]geologic[close quotes] view) thereby facilitating interpretation of reservoir distribution and interconnectivity, and (2) Al volumetrics methodology can provide more accurate estimates of average pay for reservoirs that are not seismically isolated from one another. A possible disadvantage is the difficulty in incorporating a proper baseline (low frequency) constraint for the required Al trace inversion. This paper reports the advantages and disadvantages of both techniques in characterizing net pay, volumetrics, and reservoir continuity in a producing Gulf of Mexico oil field in a shelf-edge delta depositional system.

Experimental study of a R-407C drop-in test on an off-the-shelf air conditioner with a counter-cross-flow evaporator  

SciTech Connect

An off-the-shelf 2-ton window air conditioner having an energy efficiency ratio of 10 was used to perform a drop-in test with R-407C. Laboratory tests were performed using a parallel-cross-flow (PCF) evaporator and a counter-cross-flow (CCF) evaporator. The CCF configuration is designed to take advantage of the temperature glide of R-407C so that the warm evaporator inlet air will be in contact with the higher temperature part of the evaporator coils first. The test results indicated that, at the Air Conditioning and Refrigeration Institute-rated indoor and outdoor conditions, the cooling capacity was 8% higher and system coefficient of performance about 3.8% higher for the CCF evaporator than for the PCF evaporator. The test results also showed that the latent load for CCF was 30.6% higher than for PCF. The far better dehumidification effect provided by the CCF evaporator design is desirable for areas where the latent load is high. The experimental findings should be useful for future efforts to design a dehumidifier that uses a zeotropic refrigerant that provides a significant temperature glide. R-22 test data from a previous project are included as a reference.

APPLICATION OF RESERVOIR CHARACTERIZATION AND ADVANCED TECHNOLOGY TO IMPROVE RECOVERY AND ECONOMICS IN A LOWER QUALITY SHALLOW SHELF SAN ANDRES RESERVOIR  

SciTech Connect

The OXY-operated Class 2 Project at West Welch is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO{sub 2} flood design based on the reservoir characterization. Although Budget Period 1 for the Project officially ended 12/31/96, reservoir characterization and simulation work continued during the Budget Period 2. During the seventh annual reporting period (8/3/00-8/2/01) covered by this report, work continued on interpretation of the interwell seismic data to create porosity and permeability profiles which were distributed into the reservoir geostatistically. The initial interwell seismic CO{sub 2} monitor survey was conducted and the acquired data processed and interpretation started. Only limited well work and facility construction were conducted in the project area. The CO{sub 2} injection initiated in October 1997 was continued, although the operator had to modify the operating plan in response to low injection rates, well performance and changes in CO{sub 2} supply. CO{sub 2} injection was focused in a smaller area to increase the reservoir processing rate. By the end of the reporting period three producers had shown sustained oil rate increases and six wells had experienced gas (CO{sub 2}) breakthrough.

First CSDP (Continental Scientific Drilling Program)/thermal regimes core hole project at Valles Caldera, New Mexico (VC-1): Drilling report  

DOE Green Energy (OSTI)

This report is a review and summary of the core drilling operations of the first Valles Caldera research borehole (VC-1) under the Thermal Regimes element of the Continental Scientific Drilling Program (CSDP). The project is a portion of a broader program that seeks to answer fundamental scientific questions about magma, rock/water interactions, and volcanology through shallow (<1-km) core holes at Long Valley, California; Salton Sea, California; and the Valles Caldera, New Mexico. The report emphasizes coring operations with reference to the stratigraphy of the core hole, core quality description, core rig specifications, and performance. It is intended to guide future research on the core and in the borehole, as well as have applications to other areas and scientific problems in the Valles Caldera. The primary objectives of this Valles Caldera coring effort were (1) to study the hydrogeochemistry of a subsurface geothermal outflow zone of the caldera near the source of convective upflow, (2) to obtain structural and stratigraphic information from intracaldera rock formations in the southern ring-fracture zone, and (3) to obtain continuous core samples through the youngest volcanic unit in Valles Caldera, the Banco Bonito rhyolite (approximately 0.1 Ma). All objectives were met. The high percentage of core recovery and the excellent quality of the samples are especially notable. New field sample (core) handling and documentation procedures were successfully utilized. The procedures were designed to provide consistent field handling of the samples and logs obtained through the national CSDP.

Hydrothermal brecciation in the Jemez Fault zone, Valles Caldera, New Mexico: Results from CSDP (Continental Scientific Drilling Program) corehole VC-1  

DOE Green Energy (OSTI)

Paleozoic and Precambrian rocks intersected deep in Continental Scientific Drilling Program corehole VC-1, adjacent to the late Cenozoic Valles caldera complex, have been disrupted to form a spectacular breccia sequence. The breccias are of both tectonic and hydrothermal origin, and probably formed in the Jemez fault zone, a major regional structure with only normal displacement since mid-Miocene. Tectonic breccias are contorted, crushed, sheared, and granulated; slickensides are commmon. Hydrothermal breccias, by contrast, lack these frictional textures, but arej commonly characterized by fluidized matrix foliation and prominent clast rounding. Fluid inclusions in the hydrothermal breccias are dominantly two-phase, liquid-rich at room temperature, principally secondary, and form two distinctly different compositional groups. Older inclusions, unrelated to brecciation, are highly saline and homogenize to the liquid phase in the temperature range 189 to 246/sup 0/C. Younger inclusions, in part of interbreccia origin, are low-salinity and homogenize (also to liquid) in the range 230 to 283/sup 0/C. Vapor-rich inclusions locally trapped along with these dilute liquid-rich inclusions document periodic boiling. These fluid-inclusion data, together with alteration assemblages and textures as well as the local geologic history, have been combined to model hydrothermal brecciation at the VC-1 site.

ARM - Midlatitude Continental Convective Clouds Experiment (MC3E): Multi-Frequency Profilers, S-band Radar (williams-s_band)  

DOE Data Explorer (OSTI)

This data was collected by the NOAA 449-MHz and 2.8-GHz profilers in support of the Department of Energy (DOE) and NASA sponsored Mid-latitude Continental Convective Cloud Experiment (MC3E). The profiling radars were deployed in Northern Oklahoma at the DOE Atmospheric Radiation Mission (ARM) Southern Great Plans (SGP) Central Facility from 22 April through 6 June 2011. NOAA deployed three instruments: a Parsivel disdrometer, a 2.8-GHz profiler, and a 449-MHz profiler. The parasivel provided surface estimates of the raindrop size distribution and is the reference used to absolutely calibrate the 2.8 GHz profiler. The 2.8-GHz profiler provided unattenuated reflectivity profiles of the precipitation. The 449-MHz profiler provided estimates of the vertical air motion during precipitation from near the surface to just below the freezing level. By using the combination of 2.8-GHz and 449-MHz profiler observations, vertical profiles of raindrop size distributions can be retrieved. The profilers are often reference by their frequency band: the 2.8-GHz profiler operates in the S-band and the 449-MHz profiler operates in the UHF band. The raw observations are available as well as calibrated spectra and moments. This document describes how the instruments were deployed, how the data was collected, and the format of the archived data.

Geochemical assessment of gaseous hydrocarbons: mixing of bacterial and thermogenic methane in the deep subsurface petroleum system, Gulf of Mexico continental slope  

E-Print Network (OSTI)

Mixtures of bacterial and thermogenic methane are found both at vents at the seafloor and in reservoirs in the deep subsurface of the Gulf of Mexico continental slope. The C1-C5 gas that most recently charged reservoirs of Jolliet (GC 184), Genesis (GC 160/161) and Petronius (VK 786) fields is estimated to include 17%-28%, 31%-51%, 31%-49% bacterial methane, respectively. Geochemical assessment of the reservoir gas in the fields show that the gas may be the product of thermal cracking of Upper Jurassic crude oil before final migration to the reservoirs. The gas from three different fields is of similar thermal maturity levels. In contrast to oil in reservoirs in the fields, which shows biodegradation effects, the C1-C5 reservoir gas is unaltered by biodegradation. Late gas migration may have occurred at or near present burial depth and flushed the reservoir system of previously biodegraded hydrocarbon gas to include any previous bacterial methane. Molecular and isotopic properties of reservoir gas and oil suggest that bacterial methane mixed with thermogenic hydrocarbon gas before entering the reservoirs. Thus the source of the bacterial methane is logically deeper than the present depth (>~4 km) and temperatures of the reservoirs. High sedimentation rate and low geothermal gradient may offer conditions favorable for generation and preservation of bacterial methane in deep subsurface petroleum system of the Gulf slope. Bacterial methane dispersed across the large drainage areas of the deep subsurface petroleum system may have been swept by migrating fluids at >4 km, and then charged both vents (GC 185, GC 233 and GC 286) at the seafloor and reservoirs in the deep subsurface. The volume of bacterial methane from geologically significant depth in rapidly subsiding basins may be underestimated.

ARM - Midlatitude Continental Convective Clouds  

Science Conference Proceedings (OSTI)

Convective processes play a critical role in the Earth's energy balance through the redistribution of heat and moisture in the atmosphere and their link to the hydrological cycle. Accurate representation of convective processes in numerical models is vital towards improving current and future simulations of Earths climate system. Despite improvements in computing power, current operational weather and global climate models are unable to resolve the natural temporal and spatial scales important to convective processes and therefore must turn to parameterization schemes to represent these processes. In turn, parameterization schemes in cloud-resolving models need to be evaluated for their generality and application to a variety of atmospheric conditions. Data from field campaigns with appropriate forcing descriptors have been traditionally used by modelers for evaluating and improving parameterization schemes.
