  6. Origin of the Diverse Behavior of Oxygen Vacancies in ABO3 Perovskites: A Symmetry Based Analysis

    SciTech Connect (OSTI)

    Yin, W. J.; Wei, S. H.; Al-Jassim, M. M.; Yan, Y. F.

    2012-05-15

    Using band symmetry analysis and density functional theory calculations, we reveal the origin of why oxygen vacancy (V{sub O}) energy levels are shallow in some ABO{sub 3} perovskites, such as SrTiO{sub 3}, but are deep in some others, such as LaAlO{sub 3}. We show that this diverse behavior can be explained by the symmetry of the perovskite structure and the location (A or B site) of the metal atoms with low d orbital energies, such as Ti and La atoms. When the conduction band minimum (CBM) is an antibonding {Gamma}12 state, which is usually associated with the metal atom with low d orbital energies at the A site (e.g., LaAlO{sub 3}), then the V{sub O} energy levels are deep inside the gap. Otherwise, if the CBM is the nonbonding {Gamma}25{prime} state, which is usually associated with metal atoms with low d orbital energies at the B site (e.g., SrTiO{sub 3}), then the V{sub O} energy levels are shallow and often above the CBM. The V{sub O} energy level is also deep for some uncommon ABO{sub 3} perovskite materials that possess a low s orbital, or large-size cations, and an antibonding {Gamma}{sub 1} state CBM, such as ZnTiO{sub 3}. Our results, therefore, provide guidelines for designing ABO{sub 3} perovskite materials with desired functional behaviors.

  8. Recent ooids from Mesopotamian shallow shelf, northwest Arabian Gulf

    SciTech Connect (OSTI)

    Aqrawi, A.A.M.; Sadooni, F.N.

    1987-05-01

    Petrographic and mineralogical analyses of available oolitic samples from Khor Abdulla and Khor Al-Umaya, Mesopotamian shallow shelf of the northwest Arabian Gulf, showed that the ooids exhibit extensive variations in their forms according to their nuclei shapes. The ooids cortices are usually of radial structure and are formed mainly of high magnesium calcite. The sediment distribution of the studied area revealed the existence of an oolitic zone extending NW-SE from east of Bubiyan Island toward the open sea. It is believed that these ooids are usually formed in sheltered environments by direct precipitation of high magnesium-calcite around any available nuclei. Then they are concentrated by agitation on small shoal-margins located to the east of Bubiyan Island. At these shoals they attained their final shapes and then dispersed through the studied area. It is thought that these ooids represent a peculiar example of ooid formation in quiet shallow-water environments.

    2010-02-17

    There is an enduring requirement to improve our ability to detect potential threats and discriminate these from the legitimate commercial and recreational activity ongoing in the nearshore/littoral portion of the maritime domain. The Northwest Maritime Information and Littoral Operations (NW-MILO) Program at PNNL’s Coastal Security Institute in Sequim, Washington is establishing a methodology to detect and classify these threats - in part through developing a better understanding of acoustic signatures in a near-shore environment. The purpose of the acoustic data collection described here is to investigate the acoustic signatures of small vessels. The data is being recorded continuously, 24 hours a day, along with radar track data and imagery. The recording began in August 2008, and to date the data contains tens of thousands of signals from small vessels recorded in a variety of environmental conditions. The quantity and variety of this data collection, with the supporting imagery and radar track data, makes it particularly useful for the development of robust acoustic signature models and advanced algorithms for signal classification and information extraction. The underwater acoustic sensing system is part of a multi-modal sensing system that is operating near the mouth of Sequim Bay. Sequim Bay opens onto the Straight of Juan de Fuca, which contains part of the border between the U.S. and Canada. Table 1 lists the specific components used for the NW-MILO system. The acoustic sensor is a hydrophone permanently deployed at a mean depth of about 3 meters. In addition to a hydrophone, the other sensors in the system are a marine radar, an electro-optical (EO) camera and an infra-red (IR) camera. The radar is integrated with a vessel tracking system (VTS) that provides position, speed and heading information. The data from all the sensors is recorded and saved to a central server. The data has been validated in terms of its usability for characterizing the

  4. Dolomitization of coeval shelf and fore-shelf carbonates, Lower Permian, Midland basin, Texas

    SciTech Connect (OSTI)

    Mazzullo, S.J.; Qiuchang, Ye )

    1991-03-01

    Coeval shelf and fore-shelf carbonates in Lower Permian (Leonardian) rocks in the Midland basin are pervasively dolomitized. Shelf strata consist of a regional mosaic of shelf margin reef, lagoon, and peritidal facies associated with contemporaneous evaporite deposition; fore-shelf facies consist of resedimented shelf margin deposits. Numerous relative sea-level fluctuations that resulted in the formation of Type 1 and 2 unconformities are recognized throughout this section. Mean stable oxygen and carbon isotopic compositions of the shelf strate suggest that dolomitization occurred essentially syndepositionally, likely by interaction with normal marine( ) and hypersaline fluids. In fore-shelf strata petrographic evidence, in combination with paleotemperature estimates from isotopic data and the burial depth-temperature history of these rocks, suggest relatively early (late Permian) dolomitization in rock-dominated systems. Three possible modes of dolomitization could have affected these fore-shelf beds: (1) dolomitization by reflux of normal-marine and/or hypersaline fluids during sea level highstands or lowstands; (2) dolomitization by mixed meteoric-marine fluids during lowstands; and (3) replacement by calcic dolomites via reaction with circulating marine fluids during deposition and early, shallow burial without organic matter influences. The latter mode of origin, however, is favored for most of the rocks examined on the basis of the slightly positive carbon isotopic compositions, Sr versus MgCO{sub 3} compositions (mean Sr 61 ppm, mean MgCO{sub 3} 49.5), and low Mn contents (mean 61 ppm) of the dolomites, although later burial recrystallization is indicated by their relatively depleted isotopic compositions.

    2014-01-01

    The Pacific Northwest National Laboratory (PNNL) has launched a project funded by the Bonneville Power Association (BPA) to identify strategies for increasing industrial energy efficiency and reducing energy costs of Northwest Food Processors Association (NWFPA) plants through deployment of novel combinations and designs of variable-output combined heat and power (CHP) distributed generation (DG), combined cooling, heating and electric power (CCHP) DG and energy storage systems. Detailed evaluations and recommendations of CHP and CCHP DG systems will be performed for several Northwest (NW) food processing sites. The objective is to reduce the overall energy use intensity of NW food processors by 25% by 2020 and by 50% by 2030, as well as reducing emissions and understanding potential congestion reduction impacts on the transmission system in the Pacific Northwest.

  12. Effects of tensile loading on upper shelf fracture toughness

    SciTech Connect (OSTI)

    Joyce, J.A.; Link, R.E.

    1994-03-01

    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.

    This report describes a three-dimensional ocean circulation model and two dimensional stochastic weather model used to calculate hypothetical oil-spill trajectories over the Alaskan Outer Continental Shelf (OCS) areas. Special consideration is given to the movement of sea ice in areas characterized by the presence of seasonal ice, and to ice/water interaction under different current and wind conditions. Spreading, dispersion, and weathering of crude oil, and probable landfalls of trajectories are calculated under hypothetical scenarios of oil spills from tanker accidents and well blow-outs. The report also provides comparisons between simulated data on water and sea ice motion with available field observations.

    1995-12-31

    The upper shelf fracture toughness and tearing resistance of two structural steels, HY-100 and ASTM A533, Gr. B, were determined over a wide range of applied constraint. The constraint conditions were varied by changes in specimen geometry and loading mode. Bend specimens with shallow and deep cracks, compact specimens, and single and double edge notched tension specimens were used in this study. A rotation correction was developed for the single edge notch tension specimen which greatly improved the behavior of the J-R curves determined using this specimen. The experimental results were used to investigate the applicability of the Q and T stress parameters to the correlation of upper shelf initiation toughness, J{sub Ic}, and tearing resistance, T{sub mat}. The J-Q and J-T stress loci, and corresponding plots of material tearing resistance plotted against Q and T, were developed and compared with the expectations of the O`Dowd and Shih and the Betegon and Hancock analyses. 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, T{sub mat}, is dependent on T stress and Q, with the tearing modulus increasing as constraint decreases.

  15. Preliminary studies to determine the shelf life of HEPA filters

    1994-07-18

    We have completed a preliminary study using filter media tests and filter qualification tests to investigate the effect of shelf-life on HEPA filter performance. Our media studies showed that the tensile strength decreased with age, but the data were not sufficient to establish a shelf-life. Thermogravimetric analyses demonstrated that one manufacturer had media with low tensile strength due to insufficient binder. The filter qualification tests (heated air and overpressure) conducted on different aged filters showed that filter age is not the primary factor affecting filter performance; materials and the construction design have a greater effect. An unexpected finding of our study was that sub-standard HEPA filters have been installed in DOE facilities despite existing regulations and filter qualification tests. We found that the filter with low tensile strength failed the overpressure test. The same filter had passed the heated air test, but left the filter so structurally weak, it was prone to blowout. We recommend that DOE initiate a filter qualification program to prevent this occurrence.

  16. Geometry, lateral variability, and preservation of downlapped regressive shelf deposits, eastern Tyrrhenian Margin, Italy

    SciTech Connect (OSTI)

    Field, M.E. ); Trincardi, F. )

    1990-05-01

    The shelf of the eastern Tyrrhenian margin changes substantially in width, shelf-break depth, and sea-floor steepness over relatively short distances, largely due to marked lateral changes in geologic structure. Remnants of late Pleistocene prograded coastal deposits are locally preserved on the middle and outer parts of this complex shelf. Through the authors studies of these prograded deposits they recognize two major controls on the distribution, lateral extent, thickness, and preservation potential. First, prograded (downlapped) deposits formed only where the physiographic shelf break was deeper than the lowstand shoreline, thus providing accommodation space for the lowstand deposits. Second, the proximity and relative size of sediment sources and the local coastal dispersal system influenced the geometry of the deposit. Mid-shelf and shelf-margin bodies composed of seaward-steepening downlapping reflectors were deposited as thin-to-thick continuous prograding sheets over an irregular eroded shelf surface and onto the shelf edge during the last fall and lowstand of sea level. A dearth of sediment at the end of lowstand conditions led to a switch from deposition to erosion. During sea level rise, shoreface erosion produced a major marine erosional (ravinement) surface landward of the 120-m isobath, and much, and in many places all, of the downlapping deposit was removed. Preservation of downlapping deposits is largely a function of their thickness. Thick continuous deposits are common on the shelf edge, whereas on the mid-shelf only thin remnants are preserved locally where depressions or morphologic steps were present in the shelf surface.

  17. Evolution of Permian carbonate shelf and foreshelf detrital systems, Midland basin, Texas

    SciTech Connect (OSTI)

    Mazzullo, S.J.; Reid, A.M. II; Reid, S.T.

    1986-03-01

    A major phase of shelf progradation and consequent filling of the Midland basin began in the Early Permian. Prior to this time, shelf carbonate systems were mostly ineffective in generating coarse detritus in quantities sufficient to infill adjoining basins. Beginning in the Early Permian (Wolfcampian), however, the character of shelf and basin deposition was abruptly modified, in part because of faunal changes - proliferation of rock-forming biotic communities and the consequent potential for rapid shelf-marginal oversteepening - and the effects of sea level fluctuations and periods of shale influx. Shelf systems in the northern Midland basin and Eastern shelf evolved from ramps in the lowermost Wolfcamp to steep rimmed platforms by the lower Leonard. Shelf progradation into the Midland basin was cyclic, with extensive carbonate shelves having developed during sea level highstands and massive shale wedges deposited during alternate lowstands. Coarse megabreccia with markedly little sand dominates in the lower to middle Wolfcamp systems, despite the occurrence of ramps in this section. Such an anomaly can be explained by invoking widespread shelf wastage caused by the inherent instability and failure of the shale slopes on which these ramps were deposited. In certain middle Wolfcamp zones, thin shelf-ramp sections may be recognized only because any thick shelf-marginal buildups that may have been present have been displaced into adjoining basinal tracts. The evolution to rimmed-platform shelves by the lower Leonard strata, foreshelf debris occurs mostly as complexes of megabreccia wedges and aprons, anastomosing megabreccia, and sand-channel and lobe deposits derived from adjoining rimmed-platforms. Major variations exist in the gross geometries of foreshelf units and component reservoirs even laterally within rocks of the same age.

    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.

  19. Geologic evolution of the Late Permian Capitan shelf margin, northern Delaware basin

    SciTech Connect (OSTI)

    Grover, G.A. )

    1991-03-01

    A two-phase model, based on outcrop and subsurface data rimming the northern half of the Delaware basin, characterizes the evolution of the late Guadalupian Capitan shelf margin, a margin that prograded up to 19 km basinward while an interval of over 700 m accumulated. Phase 1, during Seven Rivers shelf (early Capitan) deposition, accounts for 70-80% of the total progradation, over 50% of the total aggradation, and corresponds with shelf facies devoid of siliciclastics, emplacement of abundant carbonate debris on the slope and basin margin, and deposition of 50-70% of the Bell Canyon siliciclastic interval in the basin. The clastics bypassed the growing Capitan margin and were equally important to that of the allochthonous carbonate debris in filling accommodation space to facilitate progradation of the margin. The second phase, during Yates-Tansill (middle-upper Capitan) time, was dominated by aggradation, steepening of the shelf margin, deepening of the basin, and deposition of abundant siliciclastics on the shelf. This model differs from previous reconstructions that show uniform growth of the Capitan reef, and it contradicts the long-standing dogma of reciprocal sedimentation. This two-phase growth model adds insight into deposition of the two principle Guadalupian reservoir facies that account for nearly 50% of the Permian basin in-place oil reserves. Offlapping sheets of inner shelf carbonates (e.g., San Andres Formation, McElroy field) relate to periods of shelf progradation whereas widespread sheets of shelf clastics (e.g., Yates Formation, N. Ward Estes field) reflect periods of shelf aggradation. The model should be useful in evaluating the evolution of other shelves, particularly mixed shelves.

    California outer continental shelf crudes represent an important source of oil for energy future. They are difficult to refine, however, because of their high levels of sulfur, metals, and carbon residue. Improved Unicracking/HDS technology, made possible by a new HDM catalyst, now makes upgrading heavy crudes feasible. The authors extended this technology to upgrading California outer continental shelf crudes into a syncrude with properties similar to Alaskan North Slope crude. This is an attractive solution for handing outer continental shelf crudes in existing refineries.

    Since 1980, a number of Wolfcampian and early Leonardian oil fields have been discovered in a previously unexplored carbonate environment of the Permian basin i.e. basinal fore-shelf debris. These fields range up to 25 MMBOE in size. The Permian basin formed during the Early Pennsylvanian through the earliest Leonardian. Carbonate buildups dominated shelf-edge deposition and a syntectonic wedge of shelf debris was shed into the basins during both high and low sea level stands. Combined eustatic and tectonic sea level fluctuations of over 300 ft have been documented. The geometry, texture, and seismic expression of the debris changes with depositional slope, which ranges from very steep fault-block edges on the Central Basin platform to gentle ramps on the eastern shelf. Productive, low-stand deposits derived from steep shelf edges, consist of turbidite grainstones; clean, very coarse, lithoclastic, debris flaws; and allochthonous slide blocks. These deposits were derived from point sources on the eroded shelf and have a single-lobe or multi-lobe fan geometry. Debris clasts commonly display subaerial lithification and leaching. Lowstand fans extend 4-8 mi into the basin. Productive, lowstand deposits derived from ramp settings have a submarine channel geometry and consist dominantly of grainstone and packstone. Porosity has been enhanced by late subsurface solution. Nonproductive, highstand deposits were derived from a line source and have an apron geometry. These deposits consist of thinly bedded shaly, bioclastic turbidites with no evidence of lithification before final transport.

  3. Recent developments on the North West Shelf - an operators perspective

    Woodside is the operator of the North West Shelf Project Australia's biggest ever resource undertaking (participants - Woodside, BHP, BP, Chevron, MIMI, Shell). Major gas and condensate discoveries in the early 1970s at North Rankin, Goodwyn and Angel saw the birth of the project. The delivery of natural gas to Western Australia commenced in 1984 over a 1500km onshore pipeline, with export of LNG to eight power and gas utilities in Japan, commencing in 1989. The project delivered its 500th LNG cargo in 1995. The North Rankin and Goodwyn facilities are world class. North Rankin A is one of the biggest gas production platforms in the world, with a production capacity of more than 1800 MMscf/d. North Rankin A lies offshore in 130m of water and is connected via a 135km pipeline to the Burrup, Peninsula LNG plant and gas facility, near Dampier, Western Australia. Goodwyn A has a production capacity of over 800 MMscf/d and up to 130,000 b/d condensate. Condensate and gas are exported to North Rankin A via a 23km subsea pipeline. The Goodwyn A platform was commissioned in February, 1995. Oil production from the nearby Wanaea and Cossack fields, discovered in 1989, is planned to commence in November, 1995 at 100,000b/d. Production is via subsea well completions tied back to an FPSO facility located over Wanaea. Woodside is actively exploring to increase reserves. A 3D seismic programme covering some 27202 km is being used to identify further oil and gas prospects.

    Woodside is the operator of the North West Shelf Project Australia`s biggest ever resource undertaking (participants - Woodside, BHP, BP, Chevron, MIMI, Shell). Major gas and condensate discoveries in the early 1970s at North Rankin, Goodwyn and Angel saw the birth of the project. The delivery of natural gas to Western Australia commenced in 1984 over a 1500km onshore pipeline, with export of LNG to eight power and gas utilities in Japan, commencing in 1989. The project delivered its 500th LNG cargo in 1995. The North Rankin and Goodwyn facilities are world class. North Rankin A is one of the biggest gas production platforms in the world, with a production capacity of more than 1800 MMscf/d. North Rankin A lies offshore in 130m of water and is connected via a 135km pipeline to the Burrup, Peninsula LNG plant and gas facility, near Dampier, Western Australia. Goodwyn A has a production capacity of over 800 MMscf/d and up to 130,000 b/d condensate. Condensate and gas are exported to North Rankin A via a 23km subsea pipeline. The Goodwyn A platform was commissioned in February, 1995. Oil production from the nearby Wanaea and Cossack fields, discovered in 1989, is planned to commence in November, 1995 at 100,000b/d. Production is via subsea well completions tied back to an FPSO facility located over Wanaea. Woodside is actively exploring to increase reserves. A 3D seismic programme covering some 27202 km is being used to identify further oil and gas prospects. The Perseus-1 well, drilled in 1995 based on the 3D data, discovered a major gas accumulation in the graben between North Rankin and Goodwyn. A 770{sup 2} km 3D seismic survey was recently acquired to follow up the exciting Laminaria-1 oil discovery. Laminaria is located in 350m of water, and some 500km northwest from Darwin.

    Identifying the onset of C/sub v/ upper-shelf toughness is of paramount importance to the continued integrity of a pressure vessel. Most in-service surveillance programs require that the C/sub v/ upper-shelf toughness be determined. This is particularly true for the surveillance programs for nuclear pressure vessels. In the nuclear systems the change in C/sub v/ upper-shelf energy due to irradiation must frequently be determined with a limited number of surveillance specimens. Currently, fracture appearance is the criterion used to assure that the tests are being conducted in the C/sub v/ upper-shelf temperature range. This procedure is satisfactory when a number of specimens are available and accessible for interpretation. This is not always the case; irradiated specimens must be remotely tested and interpreted. Examining a specimen remotely may result in an erroneous interpretation of the fracture surface. To avoid this possibility we have developed a procedure, using an instrumented Charpy impact tester, that by linear extrapolation can identify the onset of the C/sub v/ upper-shelf toughness regime with as few as two specimens. This paper discusses the development of the procedure and its application.

    The surficial sediment on the continental shelf of the northern Gulf of Mexico is characterized by abundant silty clay which was deposited during the late Pleistocene lowstand and reworked during and after the Holocene transgression. The purposes of this study were to determine the sources of the silt fraction in this surficial sediment by quartz grain roundness and surface texture analysis, and to determine the effects of modern shelf currents upon the distribution of silt. Areal variations in quartz grain roundness and surface texture define six silt provinces on the northern Gulf of Mexico continental shelf. The Mississippi province is the largest province and stretches from the Chandeleur Islands to Matagorda Bay. It is characterized by a mixture of rounded grains that were derived from the sedimentary rocks of the Gulf coastal plain and the Mid-Continent, and angular, fractured grains that were derived from glacial deposits in the northern United States. A comparison of the areal distribution of these six provinces with the late Pleistocene paleogeography of the continental shelf shows evidence for varying degrees of shore-parallel transport of silt by modern shelf currents.

    1989-03-01

    This study relates the Eagle Ford-equivalent Harris delta north of the Stuart City shelf edge with the downdip Woodbine-Eagle Ford section south of that shelf edge. Together, they comprised one large deltaic complex that divided into two major lobes at an avulsion site near Anderson County. One lobe prograded southwestward toward Kurten field in Brazos County; the other (now partly eroded) prograded southeastward beside the low-lying Sabine (uplift) landmass into Polk County. The Polk County lobe crossed the Stuart City shelf edge in the Seven Oaks-Hortense field area and continued to prograde southward into deeper and higher energy water. Such an environment caused this off-shelf Harris delta to oversteepen, resulting in frequent slumps and gravity flows that deposited debris-flow and turbidite sands along with predominantly fine-grained prodelta sediments. More familiar deltaic facies (outer fringe) are present in the uppermost section. Numerous structural and stratigraphic maps and cross sections illustrate the progradation of the downdip Harris delta and its features. The progradation was arrested for a time by deeper water at the older and more precipitous Sligo shelf edge. This progradational hiatus is recorded by a relatively strong reflection that separates two seismic sequences. The younger, onlapping sequence appears to represent continued Harris delta sedimentation. Among the interesting features mapped seismically and/or geologically are mounded reflections that represent the largest slumping events, thickness anomalies associated with the carbonate substrate, and erosional( ) channels at the section top. These off-shelf Harris delta deposits appear to interfinger laterally with a genetically different eastern (Tuscaloosa ) sequence in Tyler and Jasper Counties.

    Northern Power Systems specializes in direct drive wind turbine designs. CRADA CRD-10-394 involved testing the NW2200 wind turbine power train. Power train testing is important because it allows validation of the generator design and some control algorithms prior to installation on a tower, where this data would be more difficult and time consuming to collect. In an effort to keep the commercial product schedule on time, Northern Power requested testing support from the National Renewable Energy Laboratory for this testing. The test program was performed using NREL's 2.5 MW dynamometer test bed at the National Wind Technology Center near Boulder, CO.

    There are three distinct but not mutually exclusive areas of research in this contract, studies of intrusions of the west wall of the Gulf Stream onto the outer continental shelf, studies of the flux of materials across nearshore density fronts, and advances in understanding of the planktonic food web of the continental shelf. Studies of frontal events on the outer and inner continental shelf involve distinctive physical and chemical regimes and have proven to require distinctive biological approaches. The studies of the food web run through our work on both of the frontal regimes, but certain aspects have become subjects in their own right. We have developed a simulation model of the flux of energy through the continental shelf food web which we believe to be more realistic than previous ones of its type. We have examined several of the many roles of dissolved organic compounds in sea water which originate either from release by phytoplankton, digestive processes or metabolites of zooplankton, or extracellular digestion of microorganisms. Methods have been developed under this contract to measure both the chelating capacity of naturally occurring organic materials and the copper concentration in the water. It has been possible to characterize the effects, both toxic and stimulatory, of copper on photosynthesis of naturally occurring phytoplankton populations. It is possible to characterize in considerable detail the course of biological events associated with meanders of the Gulf Stream. We are now in a position to explain the limits to biological productivity of the outer continental shelf of the southeastern US and the reasons why that biological production moves through the food web in the characteristic way that it does.

    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.

    Late Wolfcampian phylloid algal/Tubiphytes biohermal complexes are exposed in three erosional oilers lying about 3 miles west of and parallel to the main Hueco Mountains in far West Texas. The biohermal complexes are located paleogeographically along the shelf margin between the Diablo Platform and Orogrande Basin. Based on fusulinids the shelf margin buildups correlate with well-bedded shelf carbonates of the type Hueco Group in the main Hueco Mountains. The phylloid algal/Tubiphytes shelf margin bioherms contain an upward shallowing facies succession, which, in ascending order, consists of: (1) phylloid algal wackestone-bafflestone, (2) phylloid algal-fusulinid bafflestone-packstone, and (3) Tubiphytes boundstone and Tubiphytes-fusulinid-phylloid algal packstone-grainstone. The crest of the southernmost outlier has a different type of bioherm that consists of nodular boundstones composed of calcisponges, encrusting bryozoans and laminar red algae. The shelf margin complexes prograded over slope facies of dark-gray cherty limestones, which generally lack skeletal fossils, but contain common ichnofossils in upper slope beds. Overlapping tongues and channels of lithoclastic-skeletal packstones and grainstones extend seaward from the phylloid algal/Tubiphytes bioherms into the dark-gray slope facies. Proximal backreef facies consist of mainly skeletal-peloidal packstones and wackestones. The Hueco Mountains outlier exposures are important because: (1) they confirm a Late Wolfcampian shelf margin with distinct topographic relief in the southern Orogrande Basin, and (2) they provide an easily accessible field laboratory where Wolfcampian shelf-to-basin facies relationships and shelf margin bioherms can be studied. Wolfcampian bioherms represent a significant stage in the evolutionary history of Late Paleozoic reef communities and form important petroleum reservoirs in the adjacent Permian Basin.

  19. A Smoothed Particle Hydrodynamics Model for Ice Sheet and Ice Shelf Dynamics

    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) model for coupled ice sheet and ice shelf dynamics. SPH is a fully Lagrangian particle method. It is highly scalable and its Lagrangian nature and meshless discretization are well suited to the simulation of free surface flows, large material deformation, and material fragmentation. In this paper SPH is used to study ice sheet/ice shelf behavior, and the dynamics of the grounding line. The steady state position of the grounding line obtained from the 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 further verified by simulating the plane shear flow of two immiscible fluids and the propagation of a highly viscous blob of fluid along a horizontal surface. 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.

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 Glens law for the creep of polycrystalline ice. A V-shaped bedrock ramp is further introduced to model the real geometry of bedrock slope.

    This paper proposes a process for acceptance of commercial off-the-shelf (COTS) software products for use in reactor systems important to safety. An initial set of four criteria establishes COTS software product identification and its safety category. Based on safety category, three sets of additional criteria, graded in rigor, are applied to approve/disapprove the product. These criteria fall roughly into three areas: product assurance, verification of safety function and safety impact, and examination of usage experience of the COTS product in circumstances similar to the proposed application. A report addressing the testing of existing software is included as an appendix.

    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.

    A Palo geological study suggests that potential hydrocarbon reservoirs occur in shelf-margin carbonates, delta-front sandstones, and fan-delta arkoses. Zones of porous (greater than 10 percent) dolomite are concentrated near shelf margins and have configurations similar to productive Lower Permian shelf-margin trends in New Mexico. Delta-front sandstones (log-computed porosity of 18 to 25 percent) are similar to producing deltaic sandstones of Morris Buie-Blaco Fields in North-Central Texas. Porous (18 percent) fan-delta sandstones along the south flank of the Amarillo Uplift may form reservoirs similiar to that of the Mobeetie Field on the north side of the Amarillo Uplife in Wheeler County, Texas. Potential hydrocarbon source beds occur in slope and basinal environments. Total organic carbon generally ranges from 1 to 2.3 percent by weight and averages 0.589 percent by weight.

    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.

    Longshore sand ridges are frequently observed to occur on the continental shelf where the overlying ocean is stratified. This study formulates a model for the formation and evolution of three-dimensional longshore sand ridges on the continental shelf. The model is based on the interaction of interfacial, weakly nonlinear waves in a stratified ocean with the sedimentary bottom topography.

    When reactor pressure vessel steels exhibit Charpy V-notch impact upper-shelf energy levels of less than 68 J (50 ft-lb), the requirements of Title 10, Code of Federal Regulations, Part 50, Appendix G, are not met. The regulations require, as an option, that a fracture mechanics analysis be performed that conservatively demonstrates adequate safety margins for continued operation. Under conditions where large prefracture crack-tip plastic zones are present, linear-elastic fracture mechanics concepts are not applicable, and the use of elastic-plastic fracture mechanics concepts has been recommended by the US Nuclear Regulatory Commission. A number of Babcock and Wilcox Company-fabricated reactor vessels in commercial pressurized water reactor plants include welds with both relatively low initial Charpy upper-shelf energies and high copper concentrations, which make them highly sensitive to neutron irradiation. As a result, the Charpy upper-shelf energies of many welds are expected to fall below 68 J (50 ft-lb) prior to reaching design life. The Heavy-Section Steel Irradiation Program conducted the Second and Third Irradiation Series to investigate the effects of irradiation on the ductile fracture toughness of seven commercially fabricated, low upper-shelf welds. This report represents analyses of the Charpy impact and tensile test data, including adjustments for irradiation temperature and fluence normalization, which make possible comparison of the irradiation sensitivity the different welds.

    The Wider Caribbean is potentially one of the largest oil producing areas in the world. Major petroleum production areas include Louisiana and Texas, USA; the Bay of Campeche, Mexico; Lake Maracaibo, Venezuela; and Gulf of Paria, Trinidad; all of which are classified as production accident high-risk zones. About 5 million of barrels are transported every day in the Caribbean, thus generating an intense tanker traffic. It has been estimated that oil discharges from tank washings within the Wider Caribbean could be as high as 7 million barrels/year. For all those reasons petroleum pollution is considered as the major environmental problem in the Wider Caribbean area and increasing day to day due to the use of petroleum as the main energy source. On the other hand, the continental shelf of Tabasco state actually represents one of the most productive areas for crude oil in the Gulf of Mexico. Sediments were collected from this area and analyzed for hydrocarbons.

    A method is disclosed using CO for extending the useful shelf-life of refrigerated red blood cells. Carbon monoxide is utilized for stabilizing hemoglobin in red blood cells to be stored at low temperature. Changes observed in the stored cells are similar to those found in normal red cell aging in the body, the extent thereof being directly related to the duration of refrigerated storage.

    Method using CO for extending the useful shelf-life of refrigerated red blood cells. Carbon monoxide is utilized for stabilizing hemoglobin in red blood cells to be stored at low temperature. Changes observed in the stored cells are similar to those found in normal red cell aging in the body, the extent thereof being directly related to the duration of refrigerated storage. 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.

    Exploratory drilling on the Atlantic outer continental shelf remained at about the same level as in 1983. Two wells were spudded in the Baltimore Canyon Trough. Three were completed and announced as dry holes, one in a world record water depth of 6,952 ft (2,119 m). Onshore in the Atlantic coastal plain, a dry hole was drilled in Colleton County, South Carolina, and another well, drilled in 1982 in Lee County, North Carolina, was plugged and abandoned as a dry hole. North Atlantic Lease Sale 82, which was to be held in 2 parts, was cancelled in late 1984. The International Court of Justice determined the United States-Canada boundary line in the North Atlantic. Seismic data acquisition decreased 41% below the 1983 level to 7,223 line-mi(11,625 line-km).

    1981-01-01

    In July 1980, the Office of Outer Continental Shelf (OCS) Information issued an initial report called Outer Continental Shelf Oil and Gas Activities in the South Atlantic (US) and their Onshore Impacts: A Summary Report, July 1980. The purpose of this report was to provide State and local governments with current information about offshore oil and gas resources and onshore activity in the area extending from Cape Hatteras, North Carolina, to Cape Canaveral, Florida. This information was designed to assist in socioeconomic planning for the onshore impacts of oil and gas development in the affected areas. This report, Update 2, discusses Outer Continental Shelf oil and gas activities and their onshore impacts for the period of February 1981 to August 1981. Because of the minimal offshore oil- and gas-related activity in the South Atlantic Region, the onshore impacts are also minimal. Very little, if any, development has occurred as a result of exploration or development. Even though the South Atlantic OCS does contain large areas with hydrocarbon potential, little optimism has been generated by exploration associated with Lease Sale 43. Lease Sale 56 included tracts with geologic conditions more favorable to the generation, migration, and accumulation of hydrocarbons, especially the deepwatr tracts, but industry showed moderate interest in the first deepwater lease sale. The level of nearshore and onshore activity may increase with exploration associated with Lease Sale 56. More permanent onshore development will be contingent on the outcome of exploration efforts.

    In this project we determined primary production and optical variability in the shelf and slope waters off of Cape Hatteras, N.C. These processes were addressed in conjunction with other Ocean Margins Program investigators, during the Spring Transition period and during Summer. We found that there were significant differences in measured parameters between Spring and Summer, enabling us to develop seasonally specific carbon production and ecosystem models as well as seasonal and regional algorithm improvements for use in remote sensing applications.

  20. Multilayer shallow shelf approximation: Minimisation formulation, finite element solvers and applications

    SciTech Connect (OSTI)

    Jouvet, Guillaume

    2015-04-15

    In this paper, a multilayer generalisation of the Shallow Shelf Approximation (SSA) is considered. In this recent hybrid ice flow model, the ice thickness is divided into thin layers, which can spread out, contract and slide over each other in such a way that the velocity profile is layer-wise constant. Like the SSA (1-layer model), the multilayer model can be reformulated as a minimisation problem. However, unlike the SSA, the functional to be minimised involves a new penalisation term for the interlayer jumps of the velocity, which represents the vertical shear stresses induced by interlayer sliding. Taking advantage of this reformulation, numerical solvers developed for the SSA can be naturally extended layer-wise or column-wise. Numerical results show that the column-wise extension of a Newton multigrid solver proves to be robust in the sense that its convergence is barely influenced by the number of layers and the type of ice flow. In addition, the multilayer formulation appears to be naturally better conditioned than the one of the first-order approximation to face the anisotropic conditions of the sliding-dominant ice flow of ISMIP-HOM experiments.

  1. Model for the formation of longshore sand ridges on the continental shelf

    Restrepo, J.M.; Bona, J.L.

    1994-01-05

    A model is proposed for the formation and evolution of three- dimensional sedimentary structures such as longshore sand ridges on the continental shelf in water deeper than that of the shoaling region. Owing to the striking similarity between the bar spacing and the length scales in which interactions among the most energetic modes of shallow water waves take place, we argue that these bars are formed slowly by flows in the turbulent boundary layer generated by weakly nonlinear, dispersive waves. Hence the model is based on the interaction between surficial, weakly nonlinear shallow water waves, having weak spanwise spatial dependence, and the bottom topography. While such underwater structures are not the result of a single formative agent, it is argued that the mechanism proposed in this study does contribute significantly to their generation and evolution. Comparisons of this model with oceanographic data must wait for sufficient data to become available. In conjunction with developing the sand ridge model, this study proposes new mathematical equations of interest in their own right.

A cost-effective, 4 C storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. Preservation of adenosine triphosphate levels and reduction in hemolysis and in membrane vesicle production of red blood cells stored at 4 C for prolonged periods of time is achieved by removing oxygen from the red blood cells at the time of storage; in particular, by flushing with an inert gas. Adenosine triphosphate levels of the stored red blood cells are boosted in some samples by addition of ammonium phosphate. 4 figs.

    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

    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

    Rumaila and Mishrif Formations form the major part of the Cenomanian early Turonian deposits of middle and southern Iraq. The Rumaila Formation consists of lithographic chalky limestone at the lower part and marly limestone and marl at the upper part. The formation represents deep off-shelf deposits, whereas the overlying Mishrif Formation is composed of various types of shallow-shelf carbonates such as rudist-bearing patchy reefs and lagoonal and off-shelf limestones. An environmental model is suggested to delineate the stratigraphic relationships between the above mentioned two formations and to correlate them with their equivalents in central Iraq (i.e., Mahilban, Fahad, and Maotsi Formations). The gradational contact between the two formations and the intertonguing with their equivalents are considered to be the most important stratigraphic phenomena.

    Assemblages of magnetic minerals in sedimentary rocks are of depositional or diagenetic origin. Magnetic, diagenetic, and outcrop studies in rocks from the Capitan shelf margin (U. Permian), West Texas and New Mexico, show that the diagenetic history of these rocks was dominated by anhydrite cementation until uplift from Tertiary times onwards and that the magnetic minerals are of diagenetic origin. Diagenetic studies, including petrographic, cathodoluminescence and electron microprobe analysis, show that the diagenetic history can be divided into three main phases: (1) Pre-burial - cementation by calcium carbonate contemporary with deposition followed by anhydrite cementation and dolomitization. (2) Burial - continued cementation and replacement of some carbonate by anhydrite; accompanied by dolomitization. (3) uplift - minor calcitization of anhydrite accompanied by kaolinite formation. The mineralogy of magnetic particles and the age of remanence acquisition was deduced from thermal and alternating field demagnetization, despite the low magnetic mineral content of most samples. Pyrrhotite acquired remanence at around 190 Ma and from around 45 Ma to recent times. The formation of the oxides, hematite and geothite, from the oxidation of preexisting sulfides and by authigenic processes accompanied the dissolution of anhydrite and the precipitation of the calcite spar cements. These results shed new light on the diagenetic history of the Capitan shelf margin and illustrate the value of magnetic studies of sedimentary rocks when magnetic data are integrated with accompanying diagenetic studies.

    Sale of oil and gas development leases is proposed for 3561 lease tracts containing 20.3 million acres of outer continental shelf lying off the coasts of Rhode Island, New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina. The lease tracts are located beneath 132 to 10,560 feet of water within an area 24 to 140 miles offshore. Oil would become available in 1994, with production peaking in 1999. Gas production would begin in 1998, peak in 1999, and decline by approximately 50% by the year 2005. Development of the hydrocarbon field would involve approximately 22 exploratory wells, 9 delineation wells, 5 platforms, 27 subsea completions, and 54 production wells. If implemented, the lease offering would be held in October 1985.

    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

    Highlights: • The food recovery is seen as suitable way to manage food near to its expiry date. • The variability of the products shelf life must be taken into account. • The paper addresses the mathematic modeling of the profit related to food recovery. • The optimal time to withdraw the products is determinant for food recovery. - Abstract: Food losses represent a significant issue affecting food supply chains. The possibility of recovering such products can be seen as an effective way to reduce such a phenomenon, improve supply chain performances and ameliorate the conditions of undernourished people. The topic has been already investigated by a previous paper enforcing the hypothesis of deterministic and constant Shelf Life (SL) of products. However, such a model cannot be properly extended to products affected by uncertainties of the SL as it does not take into account the deterioration costs and loss of profits due to the overcoming of the SL within the cycle time. Thus the present paper presents an extension of the previous one under stochastic conditions of the food quality. Differently from the previous publication, this work represents a general model applicable to all supply chains, especially to those managing fresh products characterized by uncertain SL such as fruits and vegetables. The deterioration costs and loss of profits are included in the model and the optimal time at which to withdraw the products from the shelves as well as the quantities to be shipped at each alternative destination have been determined. A comparison of the proposed model with that reported in the previous publication has been carried out in order to underline the impact of the SL variability on the optimality conditions. The results show that the food recovery strategy in the presence of uncertainty of the food quality is rewarding, even if the optimal profit is lower than that of the deterministic case.

    The search for oil and gas on the Outer Continental Shelf in the Atlantic continues. Hydrocarbon exploration efforts have been and probably will continue to be concentrated on four major sedimentary basins: the Georges Bank Basin, the Baltimore Canyon Trough, the Carolina Trough, and the Blake Plateau Basin. To date, 46 exploratory wells have been drilled in these areas, most of them in the Mid-Atlantic Planning Area where resource estimates indicate the hydrocarbon potential is the greatest of the three Atlantic Outer Continental Shelf planning areas. Currently, no operators are involved in exploration efforts in the Atlantic. No commercial discoveries have been announced. Since the first and most successful sale of Atlantic Outer Continental Shelf blocks in Lease Sale 40 in August 1976, there have been eight other sales bringing total revenues of almost $3 billion to the Federal Treasury. The current tentative milestone chart for the 5-year offshore leasing schedule calls for four additional lease sales to be held in the Atlantic Outer Continental Shelf. Although no firm plans have been made for the transportation of potential offshore hydrocarbons to onshore processing facilities, it is believed that oil would be transported by tanker or tug-barge system to existing refineries on the Raritan and Delaware Bays. Gas probably would be transported by pipeline to one of several onshore landfalls identifed by Atlantic Coast States and in Federal environmental impact documents. Recent onshore support for Atlantic Outer Continental Shelf exploration came from Davisville, Rhode Island, the only shore support base for the Atlantic that was active during 1984. Three maps are provided in the back pocket of this report for the North Atlantic, Mid-Atlantic and South Atlantic planning areas. 29 refs., 8 figs., 6 tabs.

    1998-01-13

    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. 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 and already accounts for over 12% of the Permian Basin's daily production. 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

    1995-02-01

    The Cronifer 1925 hMo steel, which is known as a superaustenitic steel, possesses a high resistance toward pitting corrosion (PC), crevice corrosion (CC), and toward corrosion cracking (CoC) in media with a high chloride content and in hydrogen-sulfide-containing gases and condensates. The nominal chemical composition of Cronifer 1925 hMo is (%): < 0.02 C, 24.5-25.5 Ni, 20.0-21.0 Cr, < 1.0 Mn, < 0.5 Si, 0.8-1.0 Cu, 6.0-6.8 Mo, 0.18-0.20 N, < 0.005 S, and < 0.03 P. As a result of the high chromium and molybdenum content, the pitting resistance equivalent (PRE) is equal, according to the PRE equation to PRE = % Cr + 3.3% Mo - 30% N = 74%. A stainless steel is considered as corrosion-resisting in sea water at PRE {ge} 35%. The increased nickel content makes Cronifer 1925 hMo also resistant toward CoC under stress in sea water and in other media with high chloride contents, a well as in gas condensates which contain hydrogen sulfide. All this makes the steel effective for use in marine conditions and in media encountered in the shelf production of oil and gas. The addition of nickel preserves the austenitic structure and improves the passivation properties. Copper improves the resistance of the steel toward general corrosion in reducing media; however, too high a copper content is harmful when the steel is used in neutral chloride-containing solutions and must be limited (not higher than 1%). Cronifer 1925 hMo can be used in hydrocarbon production on the shelf in the following equipment: in fire-extinguishing systems which use fresh and sea water; in pipe systems which return the separated water and gases (with high chloride contents at high pressures and elevated temperatures) to the well in order to fill cavities or to maintain pressure; in separating and cooling equipment of gas and oil production platforms and in oil and gas refineries; and in underwater installations, collectors, and pipe systems, operating under pressure.

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 considered a timely effort for near-term goals. Technical progress is summarized for; geostatistical realizations; site-specific simulation;waterflood review; and reservoir characterization.

    The Oxy operated Class 2 Project at West Welch Project is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO2 injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir demonstration characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO2 flood design based on the reservoir characterization.

    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 states Outer Continental Shelf (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.

    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 Outer Continental Shelf (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.

    Work described in this report is part of a continuing effort to develop a new thermal battery technology based on the Li(Si)/FeS/sub 2/ electrochemical couple. The results reported relate to the long shelf-life requirement for thermal batteries designed by Sandia, and include topics relevant to leakage through the hermetic seal and accelerated aging experiments with materials new to the technology. Conclusions relevant to leakage through the hermetic seal are that the maximum leak rate must not exceed 1.8 x 10/sup -7/ w, where w is the grams of Li(Si) contained by a battery, and that a bomb-type leak test can be designed that is adequate for most Li(Si)/FeS/sub 2/ batteries. Conclusions relevant to long-term compatibility of new materials include the following: nickel is not compatible with the iron disulfide in the cathode; the CaSi/sub 2/ additive used to suppress the initial voltage transient does not react or degrade during accelerated aging experiments, but the use of that material can lead to an increase in the variability of the activated lives, especially for long-life batteries; Grafoil current collectors used with the cathode do not degrade in accelerated aging experiments.

    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

    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.

    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.

    This paper presents analyses of the Charpy impact and tensile test data, including adjustments for irradiation temperature and fluence normalization which make possible comparison of the irradiation sensitivity of the different welds. Analyses revealed dependence of yield and ultimate strength on irradiation temperature {minus}0.8 MPA/{degrees}C, respectively. Similarly, the Charpy impact energy changes due to irradiation temperature were {minus}0.5{degrees}C/{degrees}C for transition shift and {minus}0.05 J/{degrees}C for upper-shelf energy decrease. After adjustment to an irradiation temperature of 288{degrees}C and normalization to a fluence of 8 {times} 10{sup 18} neutrons/cm{sup 2} percentage increases in yield strength due to irradiation ranged from about 21 to 35% while those for ultimate strength ranged from about 13 to 20%. The Charpy transition temperature shifts ranged from 59 to 123{degrees}C while the postirradiation upper-shelf energies ranged from 58 to 79 J.

    The Vacuum (Glorieta) field is located on the northwest shelf of the Permian basin in central Lea County, New Mexico. Cumulative oil production of 62 MMBO is primarily from the upper 100 ft of the Leonardian Paddock Member of the Yeso Formation. Cores from 10 wells were examined to identify lithologies and facies relationships. Five lithofacies were identified: (1) fine-grained quartz sandstone/siltstone facies, (2) pelletoid mudstone facies, (3) skeletal packstone/wackestone facies, (4) oolitic-pelletoid grainstone facies, and (5) crystalline dolomite facies. These lithofacies occur sequentially in four shoaling-upward cycles that can be correlated throughout much of the study area. Three major depositional environments are recognized in the Paddock Member of the Yeso Formation: (1) a subtidal open-marine environment in which the oolitic grainstone facies was deposited, (2) a subtidal protected shallow-marine environment where the skeletal packstone/wackestone facies was deposited, and (3) a subtidal to supratidal restricted shallow-marine environment where the pelletoid mudstone facies accumulated. Facies analysis indicates that the Paddock Member was deposited on a broad shallow-marine shelf. Numerous shoaling-upward cycles are possibly related to worldwide Permian sea level fluctuations. Porosity development is enhanced at the upper surface of each shoaling-upward cycle by dissolution of fossil fragments and grains.

    Lithofacies and microfacies analysis of reservoir rocks from the Blalock Lake Southeast field indicate in-situ mound and intermound facies. Mounds grew on remnant Strawn paleohighs across a broad carbonate ramp. Two-dimensional seismic sequence stratigraphy does not confirm a well-defined shelf margin. Rocks from the Powell 8300 field are grainstone and debris-flow facies sourced from the adjacent mounds of the Blalock Lake Southeast field. The authors recognize six major lateral facies in the two field areas: the mound facies, a flanking crinoid mudstone, apron talus, intermound peloidal mudstones, capping grainstones, and downdip grainstone and debris flows. This depositional model also includes a globally documented eustatic sea level fall in the overall transgressive upper Wolfcamp - lower Leonard cycle. The perpendicular depositional trends of the mound facies and the grainstone-debris-flow facies are useful tools that can be applied to exploratory and development efforts.

    The Heavy-Section Steel Technology (HSST) Program at the Oak Ridge National Laboratory under the sponsorship of the Nuclear Regulatory Commission is conducting analytical and experimental studies aimed at understanding the circumstances that would initiate the growth of an existing crack in a reactor pressure vessel (RPV) and the conditions leading to arrest of a propagating crack. Objectives of these studies are to determine (1) if the material will exhibit crack-arrest behavior when the driving force on a crack exceeds the ASME limit, (2) the relationship between K{sub Ia} and temperature, and (3) the interaction of fracture modes (arrest, stable crack growth, unstable crack growth, and tensile instability) when arrest occurs at high temperatures. In meeting these objectives, crack-arrest data are being developed over an expanded temperature range through tests involving large thermally shocked cylinders, pressurized thermally shocked vessels, and wide-plate specimens. The wide-plate specimens provide the opportunity for a significant number of data points to be obtained at relatively affordable costs. These tests are designed to provide fracture-toughness measurements approaching or above the onset of the Charpy upper-shelf regime in a rising toughness region and with an increasing driving force.

    West Welch Unit is one of four large waterflood units in the Welch Field in the northwestern portion of Dawson County, TX. This field was discovered early 1940`s and produces oil under a solution gas drive mechanism from the Sand Adres formation at {approx}4800 ft. This field has been under waterflood for 30 yr and a significant portion has been infill drilled on 20-ac density. A 1982-86 CO{sub 2} injection project in the offsetting South Welch Unit yielded positive results. Recent installation of a CO{sub 2} pipeline near the field allowed phased development of a miscible CO{sub 2} injection project at the South Welch Unit. Reservoir quality is poorer at West Welch Unit due to relative position to sea level during deposition, and this unit is ideal for demonstrating methods for enhancing economics of IOR projects in lower quality SSC (shallow shelf carbonate) reservoirs. This Class 2 project concentrates on the efficient design of a miscible CO{sub 2} project based on detailed reservoir characterization. During the quarter, progress was made on petrophysical analysis and tomography processing. The geologic model is dependent on these, and the actual reservoir simulation cannot start until the geologic model is complete, although all the preliminary simulation work is being done.

    This analysis was updated for Annual Energy Outlook 2009 (AEO): Impact of Limitations on Access to Oil and Natural Gas Resources in the Federal Outer Continental Shelf (OCS). The 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.

    A transgressive systems tract (TST) deposit on the inner continental shelf of the south Tuscany region (central Tyrrhenian Sea, Italy) formed during the last postglacial sea-level rise. Its small-scale stratigraphy has been detailed using high-resolution seismic profiles, gravity cores, and grab samples. The TST deposit overlies a lowstand unconformity, shows a tabular geometry, and comprises three internal architectures of beach facies. Because the lateral distribution of these vertical successions is not random, but parallel to the coast, each architecture represents an individual sedimentary stage during sea-level rise. However, all architectures were formed via shoreface retreat in response to the landward migration of a beach complex over the unconformity. During this migration the beach system was characterized by a source diastem located in the surf zone and by two sediment dispersal systems. One moved the eroded sand over the flat back-barrier palustrine area by storm washover, while the other transported part of this sand to the lower shoreface, forming a reworked sand sheet above the older and inactive source diastem (ravinement surface). The TST architectures originated from a transgressive succession of beach facies, differentiated according to the intensity of shoreface retreat. Architecture A represents a low preservation potential of the original beach complex, Architecture B relatively high preservation, and Architecture C no preservation. The intensity of erosion and the consequent preservation potential were totally controlled by antecedent topography.

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.

    Slope/basin depositional systems consist of combinations of facies, including slump lobes; chute, flute, and channel fills; mounded turbidite lobes; sheet turbidites; low-density turbidite sheets and fills; hemipelagic drapes; and contourite mounds. Specific facies associations are determined by the nature (point source or linear source) and caliber (volume, grain size, sand:mud) of sediment supply to the slope. The extensive well-log, seismic, and core database was used to dissect the stratal and facies architecture of the Andrew depositional system and characterize a logical evolution of the sand-rich shelf-to-basin depositional systems tract. The andrew consists of upper and lower depositional units bounded by downlap terminations and high-gamma marker beds. The lower Andrew displays three distinct sand-rich lobes, delineated by isopach, sand percent, log motif, and seismic facies maps Proximal, mounded, sand-rich units disperse into unchannelized sheet turbidites in the basin. No extensive incised submarine valleys feed this unit, which is characterized by coarsening and thickening-upward log responses and hummocky to discontinuous reflectors. The upper Andrew downlaps the lower unit and a single, linear sediments source was centered in the Witch ground graben. The dispersal pattern and internal character suggest the upper unit is a proximal slope apron, downlapping and filling interlobe bathymetric lows of the underlying unit. Sharp-based, blocky/digitate log signatures, discontinuous chaotic reflectors, and coarse-grained sediment characterize this unit. The lower Andrew represents a structurally focused, sand-rich lobe complex, without associated incised canyons. The Andrew system evolved as the delta platform expanded onto the proximal fan, resulting in a linear sediment source spilling over the slope as a fringing slope apron.

    The search for oil and gas on the Outer Continental Shelf (OCS) in the South Atlantic Region began in 1960, when geophysical surveys of the area were initiated. In 1977, a Continental Offshore Stratigraphic Test (COST) well was drilled in the Southeast Georgia Embayment. In March 1978, the first lease sale, Sale 43, was held, resulting in the leasing of 43 tracts. Approximately a year later, in May 1979, the first exploratory drilling began, and by February 1980, six exploratory wells had been drilled by four companies. Hydrocarbons were not found in any of these wells. Lease Sale 56, the second lease sale in the South Atlantic Region, was held in August 1981. The sale resulted in the leasing of 47 tracts. Most of the leased tracts are in deep water along the Continental Slope off North Carolina. To date, no drilling has occurred on these tracts, but it is likely that two wells will be drilled or will be in the process of being drilled by the end of 1982. Reoffering Sale RS-2 is scheduled for July 1982, and it will include tracts offered in Lease Sale 56 that were not awarded leases. Lease Sale 78 is scheduled to be held in July 1983. The most recent (March 1982) estimates of risked resources for leased lands in the South Atlantic OCS are 27 million barrels of oil and 120 billion cubic feet of gas. To date, onshore impacts resulting from OCS exploration have been minimal, and they were associated with Lease Sale 43 exploratory activities. In June 1981, the South Atlantic Regional Technical Working Group prepared a Regional Transportation Management Plan for the South Atlantic OCS. The plan is principally an integration of regulatory frameworks, policies, and plans that are applicable to pipeline siting from each of the South Atlantic coastal States and Federal agencies with jurisdiction in the area.

    On March 24, 1989, the tanker Exxon Valdez ran aground and spilled over 10 million gallons of crude oil into Prince William Sound (PWS). Alaska, a deep fjord supporting large populations of birds, fish, marine mammals, and benthic organisms. We participated in 2 cruises in May and October to identify specific sedimentary areas and benthic habitats on the Alaskan shelf that may be potentially contaminated by crude oil. To identify benthic areas of potential oil impact, we measured the distribution of Beryllium-7 ([sup 7]Be 53.3-d half-life), an atmospherically deposited radioisotope, in 24 sediment cores collected in PWS and along the Kenai Peninsula at water depths ranging from 80-775 m. Like petroleum hydrocarbons, [sup 7]Be rapidly sorbs to suspended matter in coastal waters and tends to accumulate in sedimentary areas where suspended matter accumulates. The sedimentary distribution of [sup 7]Be was used to identify benthic areas that may be subject to oil contamination and for tracing dispersal and fate of this energy-related contaminant. [sup 210]Pb and [sub 137]Cs were also measured to determine an associated sediment accumulation rate at selected sites. No detectable levels of [sup 7]Be were found in surface sediments at about half of the stations. This suggests that little or no material from the water column has accumulated here in the last 3 months. Sites on the eastern side of Knight Island and along the Kenai Peninsula, downstream of the spill, had [sup 7]Be accumulation inventories ranging from 0.2 to 0.8 pCi/cm[sup 2] occurred at a site on the western side of Montague Island (246 m depth) within the the tidal mixing zone of PWS and the Gulf of Alaska. The high value suggests that water-column materials are focusing and depositing at this site so this benthic habitat may likely be affected by the oil spill. Data from new and reoccupied stations during the October cruise will be presented and areas of potential impact from oil contamination discussed.

    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: l.Advanced petrophysics 1547 2.Three-dimensional (3-D) seismic 3.Cross-well bore tomography 4.Advanced reservoir simulation 5.Carbon dioxide (CO{sub 2}) stimulation treatments 6.Hydraulic fracturing design and monitoring 7. Mobility control agents SUMMARY OF TECHNICAL PROGRESS West Welch Unit is one of four large waterflood units in the Welch Field in the northwestern portion of Dawson County, Texas. The Welch Field was discovered in the early 1940`s and produces oil under a solution gas drive mechanism from the San Andres formation at approximately 4800 ft. The field has been under waterflood for 30 years and a significant portion has been infill-drilled on 20-ac density. A 1982- 86 Pilot C0{sub 2} injection project in the offsetting South Welch Unit yielded positive results. Recent installation of a C0{sub 2} pipeline near the field allowed the phased development of a miscible CO injection project at the South Welch Unit.

    A hybrid-heating microwave oven provides the energy to heat small 10-gram samples of spent metal tritide storage bed material to release tenaciously held decay product {sup 3}He. Complete mass balance procedures require direct measurement of added or produced gases on a tritide bed, and over 1100 C is necessary to release deep trapped {sup 3}He. The decomposition of non-radioactive CaCO{sub 3} and the quantitative measurement of CO{sub 2} within 3% of stoichiometry demonstrate the capabilities of the apparatus to capture generated (released) gases.

    The Mid-Atlantic Baseline Studies Project helped address environmental barriers to offshore wind energy development in the mid-Atlantic region by providing regulators, developers, and other stakeholders with comprehensive baseline ecological data and analyses. Project funders and collaborators from a range of academic institutions, non-governmental organizations, federal agencies, foundations, and private companies came together to study bird, sea turtle, and marine mammal distributions, densities, and movements on the mid-Atlantic Outer Continental Shelf between 2012 and 2014. Specific project activities and goals included the following: (1) Conduct standardized surveys to quantify bird, sea turtle, and marine mammal densities seasonally and annually throughout the study region and identify important habitat use or aggregation areas. (2) Develop statistical models to help understand the drivers of wildlife distribution and abundance patterns. (3) Use individual tracking data for several focal bird species to provide information on population connectivity and individual movements that is complementary to survey data. (4) Identify species that are likely to be exposed to offshore wind energy development activities in the mid-Atlantic study area. (5) Develop U.S.-based technological resources and assessment methods for future monitoring efforts, including a comparison of high resolution digital video aerial surveys to boat-based surveys. (6) Help meet data needs associated with National Environmental Policy Act (NEPA), Marine Mammal Protection Act, and Endangered Species Act requirements, by contributing several years of data and analysis towards future Environmental Impact Statements. This report consists of six parts: Project overview (executive summary and Chapters 1-2); Examining wildlife distributions and relative abundance from a digital video aerial survey platform (Chapters 3-6); Examining wildlife distributions and abundance using boat-based surveys

    Many safety systems, such as those in nuclear power plants, are systems for which the consequences of failure can be severe or catastrophic. These systems must be developed, implemented, and maintained in ways that provide assurance that catastrophic consequences will be prevented. This paper discusses various aspects of the question of using commercially available software in these systems. Risk, grading, and system assessment are discussed, and relevant standards are summarized. Recommendations for addressing key issues are given.

    Montgomery, S.L.

    1997-08-01

    New exploration in the Permian (Leonardian) Bone Spring formation has indicated regional potential in several sandstone sections across portions of the northern Delaware basin. Significant production has been established in the first, second, and third Bone Spring sandstones, as well as in a new reservoir interval, the Avalon sandstone, above the first Bone Spring sandstone. These sandstones were deposited as submarine-fan systems within the northern Delaware basin during periods of lowered sea level. The Bone Spring as a whole consists of alternating carbonate and siliciclastic intervals representing the downdip equivalents to thick Abo-Yeso/Wichita-Clear Fork carbonate buildups along the Leonardian shelf margin. Hydrocarbon exploration in the Bone Spring has traditionally focused on debris-flow carbonate deposits restricted to the paleoslope. Submarine-fan systems, in contrast, extend a considerable distance basinward of these deposits and have been recently proven productive as much as 40-48 km south of the carbonate trend.

    Northwest and Far East Russia contain large quantities of unsecured spent nuclear fuel (SNF) from decommissioned submarines that potentially threaten the fragile environments of the surrounding Arctic and North Pacific regions. The majority of the SNF from the Russian Navy, including that from decommissioned nuclear submarines, is currently stored in on-shore and floating storage facilities. Some of the SNF is damaged and stored in an unstable condition. Existing Russian transport infrastructure and reprocessing facilities cannot meet the requirements for moving and reprocessing this amount of fuel. Additional interim storage capacity is required. Most of the existing storage facilities being used in Northwest Russia do not meet health and safety, and physical security requirements. The United States and Norway are currently providing assistance to the Russian Federation (RF) in developing systems for managing these wastes. If these wastes are not properly managed, they could release significant concentrations of radioactivity to these sensitive environments and could become serious global environmental and physical security issues. There are currently three closely-linked trilateral cooperative projects: development of a prototype dual-purpose transport and storage cask for SNF, a cask transshipment interim storage facility, and a fuel drying and cask de-watering system. The prototype cask has been fabricated, successfully tested, and certified. Serial production is now underway in Russia. In addition, the U.S. and Russia are working together to improve the management strategy for nuclear submarine reactor compartments after SNF removal.

    Laser Engineered Net Shaping{trademark} (LENS{reg_sign}) is a unique, layer additive, metal manufacturing technique that offers the ability to create fully dense metal features and components directly from a computer solid model. LENS offers opportunities to repair and modify components by adding features to existing geometry, refilling holes, repairing weld lips, and many other potential applications. The material deposited has good mechanical properties with strengths typically slightly higher that wrought material due to grain refinement from a quickly cooling weld pool. The result is a material with properties similar to cold worked material, but without the loss in ductility traditionally seen with such treatments. Furthermore, 304L LENS material exhibits good corrosion resistance and hydrogen compatibility. This report gives a background of the LENS process including materials analysis addressing the requirements of a number of different applications. Suggestions are given to aid both the product engineer and the process engineer in the successful utilization of LENS for their applications. The results of testing on interface strength, machinability, weldability, corrosion resistance, geometric effects, heat treatment, and repair strategy testing are all included. Finally, the qualification of the LENS process is briefly discussed to give the user confidence in selecting LENS as the process of choice for high rigor applications. The testing showed LENS components to have capability in repair/modification applications requiring complex castings (W80-3 D-Bottle bracket), thin wall parts requiring metal to be rebuilt onto the part (W87 Firing Set Housing and Y-12 Test Rings), the filling of counterbores for use in reservoir reclamation welding (SRNL hydrogen compatibility study) and the repair of surface defects on pressure vessels (SRNL gas bottle repair). The material is machinable, as testing has shown that LENS deposited material machines similar to that of welded metal. Tool wear is slightly higher in LENS material than in wrought material, but not so much that one would be concerned with increased tooling cost. The LENS process achieved process qualification for the AY1E0125 D-Bottle Bracket from the W80-3 LEP program, and in the effort, also underwent testing in weapons environments. These tests included structural dynamic response testing and drop testing. The LENS deposited parts were compared in these tests with conventionally machined parts and showed equivalency to such an extent that the parts were accepted for use in parallel path subsystem-level weapon environment testing. The evaluation of LENS has shown that the process can be a viable option when either complete metal parts are needed or existing metal parts require modification or repair. The LENS Qualification Technology Investment team successfully investigated new applications for the LENS process and showed that it has great applicability across the Nuclear Weapons Complex as well as in other high rigor applications.

  13. Tectonic controls on Upper Permian lacustrine oil shales in the Junggar basin, NW China

    SciTech Connect (OSTI)

    Carroll, A.R.; Brassell, S.C.; Graham, S.A. )

    1991-03-01

    Collision of the Tarim craton with the southern margin of Asia during the Late Carboniferous-Early Permian resulted in uplift of an ancestral Tian Shan range and geographic isolation of the previously marine Junggar basin. Dramatic shifts from marine to nonmarine sedimentation took place in both the southern Junggar and northern Tarim basins during the Permina. Paleocurrent analysis indicate that by the Late Permian, coarse-grained sediments in both basins were being supplied predominantly from the area of the Tian Shan. During the Late Permian, the southern Junggar received in excess of 5,000 m of nonmarine sediments, including approximately 1,000 m of laminated, highly organic-rich lacustrine mudstones (oil shales). These deposits commonly have TOCs of 20-30%, and Rock-Eval pyrolitic yields reaching 2,000 mg/g, ranking them among the most prolific petroleum source rocks in the world. Based on a comparison of the distribution of steranes and extended tricyclic terpanes, these Upper Permian oil shales appear to be the primary source of oils in the giant Karamay field in the northwestern Junggar basin. Ancestral uplift of the Tian Shan thus produced a complex tectono-hydrologic partitioning of the Late Permina Junggar basin, which exerted a strong influence on the character of petroleum source rocks deposited within the basin.

  14. Biomarker analysis of Upper Permian lacustrine oil shales, Junggar basin, NW China

    1990-05-01

    Upper Permian lacustrine oil shales containing up to 34% TOC (total organic carbon) underlie approximately 50,000 km{sup 2} of the Junggar basin in western China, and appear to be the principal source of oils in the giant Karamay field in the northwestern Junggar and in several recent discoveries in other areas of the basin. The siliceous oil shales were deposited in a sediment-starved foreland basin during a period of predominantly humid climate. Previous biomarker studies of crude oils from Karamay field have documented an abundance of {beta}-carotane (which in some cases dominates the aliphatic hydrocarbon distribution) and gammacerane, suggesting a source bed deposited under hypersaline conditions. However, relatively complete outcrop exposures of finely laminated oil shales in the southern Junggar conspicuously lack evaporites, extensive dessication horizons, or other sedimentological evidence of playa lake environments. Indeed, the aliphatic hydrocarbon distribution in bitumen extracts from southern Junggar oil shales appear characteristic of freshwater to brakish water deposition of organic matter in an anoxic lake. Normal alkanes show a slight odd-over-even preference with relatively low levels of the C{sub 22}, n-alkane, pristane/phytane ratios close to unity, low {beta}-carotane and gammacerane levels, and the absence of C{sub 34}-C{sub 35} hopanes. This apparent difference in source bed depositional environments may be due to tectonic partitioning between separate depocenters of the Late Permian Junggar basin. Alternatively, hypersaline oil shale facies may be limited to deeper basinal areas, whereas upslope southern Junggar sediments record highstands in lake level or influx of fresh water from the adjacent drainage areas.

Sequence and chronostratigraphic analyses indicate the section contains a broad, tectonically controlled aggradational/progradational cycle overprinted by eustatic sea level cycles. Early Leonardian deposition of the Abo Formation and the third Bone Spring sand occurred during a period of rapid subsidence, producing the aggradational geometry observed on seismic and well logs. This followed a time of uplift to the northwest of the study area, which caused enhanced shelf erosion during the late Wolfcampian. The aggradational style of deposition continued through the middle Leonardian. Late Leonardian time is characterized by progradational geometry, due to a slower subsidence rate. This resulted in a 15-km progradation of the Bone Spring shelf margin in the northwestern part of the Delaware basin. A second period of uplift to the northwest followed, leading to the deposition of the sands of the Brushy Canyon Formation (Guadalupian). This aggradational/progradational cycle is followed by a similar cycle which ends after the deposition of the Capitan Formation. Within the carbonate-dominated Leonardian aggradational/progradational cycle, nine sea level cycles are recognized. The lowstand systems tracts within this package are of two types. The lowstands within the aggradational part of the section consist primarily of slope fans, while those associated with progradation contain large lowstand prograding wedges. Steep margins are associated with aggradation, while progradation is characterized by a ramplike geometry. Highstands are widespread on the shelf and prograde into the basin throughout this interval.

    Mesaverde Group sandstone units in 13 closely-spaced wells in the central and southern Piceance Basin of Colorado were correlated utilizing wireline log response quantitatively and qualitatively. Based on these correlations, the environmental subdivisions of the Mesaverde Group were characterized as follows: (1) paralic (upper mixed-marine) zone, occurring in the uppermost Mesaverde Group, includes thick sandstone units which are interpreted to be regionally continuous, (2) fluvial zone, containing point-bars 20 to 30+ ft thick, is interpreted to be correlatable to a maximum of 6800 ft, and (3) paludal zone has insufficient data to adequately characterize the sand units. However, 63 percent of the units are correlatable across at least 139 ft. An approximation of the dimensional characteristics of Mesaverde sandstone units has potential applications in designing hydraulic fracturing treatments and estimating gas reserves more accurately. 15 figures, 2 tables.

  1. Final Technical Report, 30 SEPTEMBER 2002 - 31 JANUARY 2006; ENERGY PARTIONING FOR SEISMIC EVENTS IN FENNOSCANDIA AND NW RUSSIA

    In this project we have addressed the problem of energy partitioning at distances ranging from very local to regional for various kinds of seismic sources. On the local and regional scale (20-220 km) we have targeted events from the region offshore Western Norway where we have both natural earthquake activity as well as frequent occurrence of underwater explosions carried out by the Norwegian Navy. On the small scale we have focused on analysis of observations from an in-mine network of 16-18 sensors in the Pyhasalmi mine in central Finland. This analysis has been supplemented with 3-D finite difference wave propagation simulations in a realistic mine model to investigate the physical mechanisms that partition seismic energy in the near source region in and around the underground mine. The results from modeling and analysis of local and regional data show that mean S/P amplitude ratios for explosions and natural events differ at individual stations and are in general higher for natural events and frequency bands above 3 Hz. However, the distributions of S/P ratios for explosions and natural events overlap in all analyzed frequency bands. Thus, for individual events in our study area, S/P amplitude ratios can only assist the discrimination between an explosion or a natural event. This observation is supported by synthetic seismograms calculated for simple 1-D models which demonstrate that explosions also generate shear-wave energy if they are fired close to an interface with a strong material contrast (as is the case for most explosions), e.g., free surface or the ocean bottom. The larger difference in S/P ratios between earthquakes and explosions for higher frequencies can be explained by the fact that at low frequencies (larger wavelengths), discontinuities and structural heterogeneities in the explosion source region are stronger generators of converted S energy. The S*-phase, for example, is most efficiently generated whenever an explosion source is located close (within one wavelength) to a strong discontinuity. The Pyhasalmi explosions have generally lower S/P ratios than the rockbursts for all frequencies, but the difference is far too small to be significant for classification purposes. The maxima for the explosion distributions are all below 2, whereas they are all above 2 for the rockbursts. The rockbursts also have a wider distribution of S/P ratios, which can be explained by the variability of the radiation patterns from the rockburst sources. S/P ratios for explosions and rockbursts located in the same small area of the mine show results very similar to those for the full data set. This indicates that the observed differences in S/P ratios between explosions and rockbursts are due to differences in the source characteristics, and not due to propagation effects along paths in the mine. 3-D finite-difference simulations were used to model seismic events within the Pyhasalmi mine. In particular, a January 26, 2003 rockburst was modeled at frequencies of 50 Hz (4 meter grid) and 100 Hz (2 meter grid). We were able to match the characteristics of the observed data at 50 Hz particularly well, and the characteristics of the 100 Hz data reasonably well. These results help validate the 3-D geologic mine model and the reliability of our simulations. The simulations showed that significant shear-energy can be produced due to the geologic and structural heterogeneities within the mine. In fact, mode-converted shear-energy generated from mine heterogeneity can dominate the compressional energy from an explosive source. A strong correlation is observed between the distance of a source from a mine heterogeneity and the magnitude of generated shear-energy. The ratio of shear to compressional energy is about a factor of two larger when the source is located within one wavelength from a mine heterogeneity. The simulations also suggest that excavated mine volumes are significantly stronger contributors to shear-energy generation than geologic heterogeneities. However, the simulations reveal that the magnitude of shear-energy ge

    Phase II, Series 2 corrosion testing performed by the Savannah River National Laboratory (SRNL) for the Department of Energy 3013 container has been completed. The corrosion tests are part of an integrated plan conducted jointly by Los Alamos National Laboratory and the Savannah River Site. SRNL was responsible for conducting corrosion studies in small-scale vessels to address the influence of salt composition, water loading, and type of oxide/salt contact on the relative humidity inside a 3013 container and on the resulting corrosion of Type 304L and 316L stainless steel (304L and 316L). This testing was conducted in two phases: Phase I evaluated a broad spectrum of salt compositions and initial water loadings on the salt mixtures exposed to 304L and 316L and the resulting corrosion; Phase II evaluated the corrosion of 304L at specific water loadings and a single salt composition. During Phase I testing at high initial moisture levels (0.35 to 1.24 wt%)a, the roomtemperature corrosion of 304L exposed to a series of plutonium oxide/chloride salt mixtures ranged from superficial staining to pitting and stress corrosion cracking (SCC). 304L teardrop coupons that exhibited SCC were directly exposed to a mixture composed of 98 wt % PuO2, 0.9 wt % NaCl, 0.9 wt % KCl, and 0.2 wt % CaCl2. Cracking was not observed in a 316L teardrop coupon. Pitting was also observed in this environment for both 304L and 316L with depths ranging from 20 to 100 ?m. Neither pitting nor SCC was observed in mixtures with a greater chloride salt concentration (5 and 28 wt%). These results demonstrated that for a corrosive solution to form a balance existed between the water loading and the salt chloride concentration. This chloride solution results from the interaction of loaded water with the hydrating CaCl2 salt. In Phase II, Series 1 tests, the SCC results were shown to be reproducible with cracking occurring in as little as 85 days. The approximate 0.5 wt% moisture level was found to result in an initial relative humidity of ~55% within the small-scale vessels. Pits were found to be associated with cracks and appeared to act as initiators for the cracking. In a vapor-space only exposure, the weld oxide, which results from the TIG closure weld used to fabricate the teardrop coupon, was also shown to be more susceptible to pitting corrosion than a surface free from weld oxide. This result has important implications for the closure weld of the 3013 inner can since the weld oxide on the can internal surface cannot be removed. The results from the Phase II, Series 2 tests further demonstrated the significance of forming a solution with a critical chloride concentration for corrosion to proceed. 304L teardrop coupons were found to corrode only by pitting with a similar oxide/salt mixture as used in Series 1 testing but with a lower water loading of 0.2 wt%, which resulted in an initial relative humidity of 35-38%. These tests ran twice as long as those for Series 1 testing. The exposure condition was also found to impact the corrosion with salt-exposed surfaces showing lower corrosion resistance. Additional analyses of the Series 2 coupons are recommended especially for determining if cracks emanate from the bottom of pits. Data generated under the 2009 3013 corrosion test plan, as was presented here, increased the understanding of the corrosion process within a sealed 3013 container. Along with the corrosion data from destructive evaluations of 3013 containers, the inner can closure weld region (ICCWR) has been identified as the most vulnerable area of the inner can where corrosion may lead to corrosive species leaking to the interior surface of the outer container, thereby jeopardizing the integrity of the 3013 container. A new corrosion plan has been designed that will characterize the corrosion at the ICCWR of 3013 DEs as well as parameters affecting this corrosion.

    The Paradox basin of Utah, Colorado, and Arizona contains nearly 100 small oil fields producing from carbonate mounds within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to three wells with primary per field production ranging from 700 MBO to 2 MMBO at a 15-20% recovery rate. Five fields (Anasazi, Mule, Blue Hogan, Heron North, and Runway) within the Navajo Nation of southeastern Utah have been evaluated for CO{sub 2}-flood projects based upon geological characterization and reservoir modeling. Conventional cores from the five fields show that three compositional reservoir types are present: (1) phylloid algal, (2) bioclastic calcarenite, and (3) bryozoan-dominated. Phylloid algal mounds are abundant in four of the five fields, and exhibit the best overall porosity and permeability. This mound type developed where shallow water depths and low energy allowed establishment of calcareous algal colonies possibly on paleohighs. The principal reservoir rock is algal bafflestone composed mostly of the phylloid Ivanovia and occasionally dolomitized. The Heron North field is a bioclastic calcarenite reservoir. It represents high-energy conditions resulting in carbonate beaches developed over foreshore carbonate rubble. The principal reservoir rocks are grainstones and rudstones having grain-selective dissolution and complete dolomitization. Bryozoan-dominated mounds present in Runway field developed in quiet, below wave-base settings that appear to be localized along Mississippian fault blocks trends. The principal reservoir rocks are bindstone and framestone with no dolomitization. The resulting model suggests that CO{sub 2} miscible flooding of these and other small carbonate reservoirs in the Paradox basin could significantly increase ultimate recovery of oil.

    For many large ferritic steel pressure vessels, assurance of continued safe operation depends on the fracture toughness properties of the base metals and weld metals which are used in the vessel fabrication. The testing procedure discussed in this paper was developed for nuclear pressure vessel steels and their weldments. Consequently these materials served as the basis for the development of the procedure. The procedure is applicable to any steel and hence 2/one quarter/ Cr-1 Mo (A 387 grade D) and C-Mn-Si (A 212 grade B) steels were included in this study. 11 refs.

    Pennyslvanian and Lower Permian shelfal limestones were studied in core and wireline logs on the eastern side of the Central Basin platform in west Texas. Sixty-three (63) cycles were delineated in the study interval, which includes 200-250 m of Canyon (Missourian), Cisco (Virgilian), and Wolfcamp strata. Four general lithofacies are present: fossiliferous wackestones and packstones, grainstones, phylloid algal boundstones, and shales. These lithologies typically occur in 1-18-m-thick cycles bounded by subaerial exposure surfaces. Grainstones in the upper part of some cycles indicate a shallowing of environments prior to subaerial exposure. Many cycles have subaerial exposure surfaces developed on subtidal fossiliferous wackestones or packstones suggesting rapid falls in sea level. Long-term transgressive intervals (transgressive systems tracts or TST) are dominated by thick (>4 m) cycles, whereas long-term regressive intervals (highstand systems tract or HST) are dominated by thinner cycles. Stable carbon isotope data suggest that thick cycles in TSTs were subjected to short periods of subaerial exposure, whereas thin cycles in the HSTs were subjected to much longer subaerial exposure. Where present, reservoir-grade porosity occurs in the upper part of cycles, 0.3-5 m below subaerial exposure surfaces. Prolonged subaerial exposure apparently reduced matrix porosity by allowing more time for calcite precipitation, which was especially effective in reducing porosity in micritic strata below exposure surfaces.

    The Honaker Trail, Paradox, and Pinkerton Trail Formations of the Hermosa Group are recognized throughout most of the San Juan basin. The Paradox Formation is extended southeastward beyond the limits of its evaporite facies into the basin, where it consists of thick shelf-carbonate rocks and thin black shale, sandstone, and siltstone interbeds. Where the Hermosa Group thins onto the marginal uplifts, the Paradox loses the thick carbonate rocks and becomes indistinguishable from the rest of the Hermosa. The Hermosa is correlated in the subsurface with the Madera and Sandia Formations to the southeast. The transitional Rico Formation, between the marine Hermosa Group and the continental Cutler Formation, is identified throughout the subsurface of the San Juan basin and is correlated with similar deposits out-cropping along the northern and eastern margins. The Cutler Formation includes the Organ Rock, Cedar Mesa, and Halgaito members throughout most of the basin. In the vicinity of the Hogback monocline, the Cedar Mesa Sandstone Member undergoes a gradational eastward facies change from cyclic evaporite and sandstone to thick-bedded sandstone. The subsurface Cedar Mesa is correlated in part with similar rocks in the outcropping Abo and Supai Formations.

  9. EIS-0470: U.S. Department of Energy Loan Guarantee for the Cape Wind Energy Project on the Outer Continental Shelf off Massachusetts, Nantucket Sound

    Broader source: Energy.gov [DOE]

    The DOE Loan Programs Office is proposing to offer a loan guarantee to Cape Wind Associates, LLC for the construction and start-up of the Cape Wind Energy Project in Nantucket Sound, offshore of Massachusetts. The proposed Cape Wind Energy Project would consist of up to 130, 3.6-MW turbine generators, in an area of roughly 25-square miles, and would include 12.5 miles of 115-kilovolt submarine transmission cable and an electric service platform. To inform DOE's decision regarding a loan guarantee, DOE adopted the Department of the Interior’s 2009 Final Cape Wind Energy Project EIS, in combination with two Cape Wind Environmental Assessments dated May 2010 and April 2011 (per 40 CFR 1506.4), as a DOE Final EIS (DOE/EIS-0470). The adequacy of the Department of the Interior final EIS adopted by DOE is the subject of a judicial action. This project is inactive.

    The work reported herein covers select tasks in Budget Phase 11. The principle Task in Budget Phase 11 included in this report is Field Demonstration. Completion of many of the Field Demonstration tasks during the last report period enabled an optimum carbon dioxide (CO{sub 2}) flood project to be designed, economically evaluated, and implemented in the field. Field implementation of the project commenced during late 1995, with actual C0{sub 2} injection commencing in mid-July, 1996. This report summarizes activities incurred following initial project start-up, towards the goal of optimizing project performance. The current project has focused on reducing initial investment cost by utilizing horizontal injection wells and concentrating the project in the best productivity area of the field. An innovative C0{sub 2} purchase agreement (no take-or-pay provisions, C0{sub 2} purchase price tied to West Texas Intermediate (WTI) crude oil price) and gas recycle agreement (expensing costs as opposed to a large upfront capital investment for compression) were negotiated to further improve the project economics. The Grayburg-San Andres section had previously been divided into multiple zones based on the core study and gamma ray markers that correlate wells within the Unit. Each zone was mapped as continuous across the field. Previous core studies concluded that the reservoir quality in the South Cowden Unit (SCU) is controlled primarily by the distribution of a bioturbated and diagenetically-altered rock type with a distinctive chaotic texture. The chaotic modifier is derived from the visual effect of pervasive, small-scale intermixing of tan oil-stained reservoir rock with tight gray non- reservoir rock. The chaotic reservoir rock extends from Zone C (4780`-4800`) to the lower part of Zone F (4640`-4680`). Zones D (4755`-4780`) and E (4680`-4755`) are considered the main floodable zones, though Zone F is also productive and Zone C is productive above the oil- water contact. During Budget Phase 1, the Stratamodel computer program was utilized as the primary tool to integrate the diverse geologic, petrophysical, and seismic data into a coherent three dimensional (3-D) model. The basic porosity model having been constructed, critiqued and modified based on field production and detailed cross-section displays, permeability data was imported into the model, and a 3-D interpolation of the permeability was completed.

    The purpose of this project was to economically design an optimum carbon dioxide (CO2) flood for a mature waterflood nearing its economic abandonment. The original project utilized advanced reservoir characterization and CO2 horizontal injection wells as the primary methods to redevelop the South Cowden Unit (SCU). The development plans; project implementation and reservoir management techniques were to be transferred to the public domain to assist in preventing premature abandonment of similar fields.

    The purpose of this project was to economically design an optimum carbon dioxide (CO{sub 2}) flood for a mature waterflood nearing its economic abandonment. The original project utilized advanced reservoir characterization and CO{sub 2} horizontal injection wells as the primary methods to redevelop the South Cowden Unit (SCU). The development plans; project implementation and reservoir management techniques were to be transferred to the public domain to assist in preventing premature abandonment of similar fields. The Unit was a mature waterflood with water cut exceeding 95%. Oil must be mobilized through the use of a miscible or near-miscible fluid to recover significant additional reserves. Also, because the unit was relatively small, it did not have the benefit of economies of scale inherent in normal larger scale projects. Thus, new and innovative methods were required to reduce investment and operating costs. Two primary methods used to accomplish improved economics were use of reservoir characterization to restrict the flood to the higher quality rock in the unit and use of horizontal injection wells to cut investment and operating costs. The project consisted of two budget phases. Budget Phase I started in June 1994 and ended late June 1996. In this phase Reservoir Analysis, Characterization Tasks and Advanced Technology Definition Tasks were completed. Completion enabled the project to be designed, evaluated, and an Authority for Expenditure (AFE) for project implementation submitted to working interest owners for approval. Budget Phase II consisted of the implementation and execution of the project in the field. Phase II was completed in July 2001. Performance monitoring, during Phase II, by mid 1998 identified the majority of producing wells which under performed their anticipated withdrawal rates. Newly drilled and re-activated wells had lower offtake rates than originally forecasted. As a result of poor offtake, higher reservoir pressure was a concern for the project as it limited CO{sub 2} injectivity. To reduce voidage balance, and reservoir pressure, a disposal well was therefore drilled. Several injection surveys indicated the CO{sub 2} injection wells had severe conformance issues. After close monitoring of the project to the end of 1999, it was evident the project would not recover the anticipated tertiary reserves. The main reasons for under-performance were poor in zone CO{sub 2} injection into the upper San Andres layers, poorer offtake rates from newly drilled replacement wells and a higher than required reservoir pressure. After discussion internally within Phillips, externally with the Department of Energy (DOE) and SCU partners, a redevelopment of South Cowden was agreed upon to commence in year 2000. The redevelopment essentially abandoned the original development for Budget Phase II in favor of a revised approach. This involved conformance techniques to resolve out of zone CO{sub 2} injection and use of horizontal wells to improve in zone injectivity and productivity. A phased approach was used to ensure short radius lateral drilling could be implemented effectively at South Cowden. This involved monitoring drilling operations and then production response to determine if larger investments during the second phase were justified. Redevelopment Phase 1 was completed in May 2000. It was deemed a success in regard to finding suitable/cost-effective technology for drilling horizontal laterals and finding a technique that could sustain long-term productivity from the upper layers of the San Andres reservoir. Four existing vertical producing wells were isolated from their existing completions and sidetracked with horizontal laterals into the upper layers of the San Andres. Overall average offtake rates for the four wells increased by a factor of 12 during the first four months after completion of Phase 1. Phase 2 of the redevelopment focused on current CO{sub 2} vertical injection wells. Techniques were applied to resolve near well conformance concerns and then either single or dual laterals were drilled in the upper layers. Additional work required conformance resolution with a horizontal injection well and additional lateral drilling from four existing producing wells. Although Phase 1 had provided a short-term boost to lease offtake, it was Phase 2, by ensuring in zone CO{sub 2} injection in all existing vertical wells, which would provide the longer-term reserve recovery from the upper San Andres. Phase 2 activities commenced in October 2000 with drilling a single lateral in an existing CO{sub 2} injector. Four dual lateral and one single lateral CO{sub 2} injection wells were completed from existing wellbores to replace the poorly performing CO{sub 2} vertical injection wells. Four additional single laterals from existing vertical production wells were also completed. Phase 2 was completed in April 2001.

    Presented in this quarterly report is the Case History and Well Summary for the Vernon Field demonstration project in Isabella County, Michigan. This new case history and well summary format organizes and presents the technical and historical details of the Vernon Field demonstration, as well as the field demonstration results and the applicability of these results to other demonstration projects. This format could be duplicated for other demonstration projects and will be used on all subsequent field demonstrations as they near completion. Planning for the annual project meeting in Tampa, Florida has begun. This meeting will be held March 7-9, 2003 at the same site as the last three meetings. The goals of this project were to: (1) test the use of multi-lateral wells to recover bypassed hydrocarbons and (2) to access the potential of using surface geochemistry to reduce drilling risk. Two new demonstration wells, the State-Smock and the Bowers 4-25, were drilled to test the Dundee Formation at Vernon Field for bypassed oil. Neither well was commercial, although both produced hydrocarbon shows. An extensive geochemical survey in the vicinity of Vernon Field, covering much of Isabella County, has produced a base map for interpretation of anomalies in Michigan. Several potential new anomalies were discovered that could be further investigated.

    One of the main objectives of this demonstration project is to test surface geochemical techniques for detecting trace amounts of light hydrocarbons in pore gases as a means of reducing risk in hydrocarbon exploration and production. As part of the project, several field demonstrations were undertaken to assess the validity and usefulness of the microbial surface geochemical technique. The important observations from each of these field demonstrations are briefly reviewed in this annual report. These demonstrations have been successful in identifying the presence or lack of hydrocarbons in the subsurface and can be summarized as follows: (1) The surface geochemistry data showed a fair-to-good microbial anomaly that may indicate the presence of a fault or stratigraphic facies change across the drilling path of the State Springdale & O'Driscoll No.16-16 horizontal demonstration well in Manistee County, Michigan. The well was put on production in December 2003. To date, the well is flowing nearly 100 barrels of liquid hydrocarbons per day plus gas, which is a good well in Michigan. Reserves have not been established yet. Two successful follow-up horizontal wells have also been drilled in the Springdale area. Additional geochemistry data will be collected in the Springdale area in 2004. (2) The surface geochemistry sampling in the Bear Lake demonstration site in Manistee County, Michigan was updated after the prospect was confirmed and production begun; the original subsurface and seismic interpretation used to guide the location of the geochemical survey for the Charlich Fauble re-entry was different than the interpretation used by the operator who ultimately drilled the well. As expected, the anomaly appears to be diminishing as the positive (apical) microbial anomaly is replaced by a negative (edge) anomaly, probably due to the pressure draw-down in the reservoir. (3) The geochemical sampling program over the Vernon Field, Isabella County, Michigan is now interpreted as a large negative anomaly associated with the entire field. The results of the State Smock horizontal well and the Bowers 4-25 well confirmed the lack of additional recoverable hydrocarbons in the Vernon Field. (4) The surface geochemistry data showed a strong anomaly in the Myrtle Beach, Burke County, North Dakota area that would justify drilling by itself and even more so in conjunction with the structural interpretation from the geological and geophysical data; the microbial values here were the highest we have observed. The Myrtle Beach geochemical survey indicated a good to excellent prospect which was confirmed by drilling, however, a pipeline has not yet been completed that would allow the wells to be placed into production. We also present in this annual report the results of recent efforts to map carbonate facies tracts in the middle Devonian Dundee and Rogers City Limestones using gamma ray, bulk density, and photoelectric effect geophysical well log amplitudes. This work was undertaken to identify fairways for exploration in the Dundee and Rogers City where surface geochemical techniques could then be used to screen potential leads.

    This report covers research activities for the second half of the second project year (October 6, 2001, through April 5, 2002). This work includes description and analysis of cores, correlation of geophysical well logs, reservoir mapping, petrographic description of thin sections, cross plotting of permeability and porosity data, and development of horizontal drilling strategies for the Little Ute and Sleeping Ute fields in Montezuma County, Colorado. Geological characterization on a local scale focused on reservoir heterogeneity, quality, and lateral continuity, as well as possible compartmentalization, within these fields. This study utilizes representative core, geophysical logs, and thin sections to characterize and grade each field's potential for drilling horizontal laterals from existing development wells.

    Three air type solar collector modules using vacuum insulated bottles and three different absorbers were designed, built, and simultaneously tested for comparison of performance. One absorber was flat black paint on cylinders, one was black chrome on copper cylinders and one was ordinary dark brown house insulation known as rock wool. A liquid type solar collector was also designed, built, and tested, which employed similar components of the air type collectors except for painted cans inserted in the short vacuumware bottles serving as the evacuated-tubes. Similar tests were made of flat plate type solar collectors using similar absorbers. The results of these tests are presented.

    The Exxon 975--1 well, located in the southeastern part of the Georges Bank Basin, was drilled to a total depth of 4,452 m relative to the Kelly Bushing. The oldest sediments penetrated by the well are Middle Jurassic (Bajocian-Early Bathonian), but unambiguous seismic correlations with the COST G--1 and G--2 wells show that about 6,860 m of Mesozoic and Cenozoic sedimentary rocks rest on the Paleozoic basement at the 975--1 wellsite. The Jurassic/Cretaceous boundary in the well is placed at 1,673 m; the Cretaceous/Tertiary boundary occurs at 384 m. Limestone is predominant below 3,966 m (Iroquois Formation), and at the intervals 3,810--3,246 m and 1,897--1,654 m (lower and upper tongues of the Abenaki Formation). Siliciclastics of the Mohican, undivided Mic Mac-Mohawk, Missisauga, Logan Canyon, and Dawson Canyon Formations dominate the remainder of the Mesozoic section. The Exxon 975--1 well penetrated updip, more terrestrial lithofacies than the COST G--2, Conoco 145--1, and Mobil 312--1 wells. Salt, anhydrite, dolomite, and the micritic textures of the carbonates in the Iroquois Formation of the Exxon 975--1 well suggest hypersaline restricted marine and supratidal depositional environments. The predominantly nonmarine deltaic siliciclastics of the Mohican, Misaine Shale, and Mic Mac-Mohawk units are thicker in the Exxon 975--1 well, whereas marine carbonates of the Scatarie and Bacarro Limestones are usually thinner than at the downdip (seaward) wellsites. Similarly, the Early Cretaceous Missisauga and Logan Canyon Formations represent lower delta plain (alluvial and swamp) and delta front (beach, bar, and lagoon) facies at the Exxon 975--1 wellsite, whereas correlative downdip facies represent shallow marine to delta front deposition.

    Vertical and horizontal transects were sampled from core and outcrop of the San Andres Formation at Lawyer Canyon, Guadalupe Mountains, New Mexico, to assess permeability variation in a geologic framework of upward-shallowing carbonate cycles and to show the potential effect these variations have on viscous-dominated flow behavior in analogous reservoirs. These cycles occur in a ramp-crest facies, tract, are 3-13 m (10-45 ft) thick, and contain both vertical and lateral variation of lithofacies. Thicker cycles consist of a basal dolomudstone, which is overlain by burrowed dolomudstone, and capped by bar-flank ooid-peloid dolograinstone and bar-crest ooid dolograinstones. In vertical transects, permeability is extremely variable about the mean, yet upward-increasing trends coinciding with the succession of lithofacies typify a given cycle. Semi-variance analysis shows permeability to be uncorrelated vertically at distances greater than 5.5 m (18 ft), which is the average cycle thickness, suggesting that the cycles may equate to fluid-flow unit in a reservoir. Semi-variance analysis of measurements collected along a horizontal transect within bar-crest dolograinstones of a single cycle show permeability is uncorrelated at distances greater than 3.6 m (12 ft). This correlation distance appears to be controlled by alternating porous and tightly cemented zones that formed during dolomitization. Vertical and lateral variogram models were fit to the spatial parameters to generate a variety of conditionally simulated permeability fields. Fluid-flow simulations show viscous-dominated flow behavior is compartmentalized by both the individual cycles and groups of cycles. The basal dolomudstones are potential baffles to flow crossover between cycles, but poorly developed cycles (i.e., those that are mud rich and lack well-developed bar-flank and bar-crest facies) result in the greatest compartmentalization of fluid flow within a succession of cycles.

    At the present, there are no operators drilling in the Mid-Atlantic Region. The prime targets for future exploration will be in areas of 3000 to 6000 feet (914 to 1829 m) depth of water, seaward of previously leased tracts. No commercial discoveries have been found during the 4-year drilling history of the area. Because of the minimal offshore oil- and gas-related activity in the Mid-Atlantic Region, the onshore impacts are also minimal. Little development has occurred as a result of exploration or development. The level of nearshore and onshore activity may increase with exploration associated with upcoming Lease Sale 59. More permanent onshore development will be contingent on the outcome of future exploration efforts. After Lease Sale 59, the next sale is Lease Sale 76, which is tentatively scheduled for March 1983.

    Lease Sale 43, in the Southeast Georgia Embayment, was the first lease sale to be held in the South Atlantic. Two additional sales are scheduled between now and 1985: Sale 56 is scheduled for August 1981 and Sale 78, for January 1984. All leases from Sale 43 remain active, but no drilling has taken place since the last of six dry holes was plugged and abandoned. There are no additional plans for drilling on Sale 43 leases in the immediate future. Future exploration may shift away from previous Sale 43 leased tracts to deep-water areas after Sale 56. One hundred thirty of the 286 proposed Sale 56 tracts are in deep-water. The geologic conditions in the deep-water areas are more favorable for hydrocarbon accumulation than those under shallower waters. Structures that may provide trapping mechanisms have been shown to exist in the area. Because leases in deep-water areas take longer and are more costly to explore and develop than those in areas of shallower water, industry consensus is that longer primary lease terms may be required and some delays in acquiring rigs may be experienced. The Sale 43 area appears to be a region of relatively low hydrocarbon-bearing potential. However, the Bureau of Land Management's Intergovernmental Planning Program is preparing the necessary Regional Transportation Management Plan for the entire South Atlantic OCS Region. Nearly all the support facilities associated with Sale 43 have been removed or converted to other uses. Temporary support facilities are likely to be reactivated only if Sale 56 results in further exploration of the South Atlantic OCS.

    Strata of the Middle Pennsylvanian to Lower Permian Oquirrh-Wood River Basin (OWRB) lie unconformably above the Antler orogenic belt and flysch trough/starved basin in NW Utah, NE Nevada, and SC Idaho. Strata of the basin, now separated geographically by the Neogene Snake River Plain, show similar subsidence histories, identical mixed carbonate-siliciclastic sedimentary fill, and identical chert pebble conglomerate beds supplied by one or more DesMoinesian uplifts containing Lower Paleozoic strata. This conglomerate, of the lower Sun Valley Group, Snaky Canyon Formation, and parts of the Oquirrh Formation, was reworked progressively southward, to at least the Idaho-Utah border. It is present in strata as young as Virgilian. Virgilian to Leonardian rocks are ubiquitously fine-grained mixed carbonate-siliciclastic turbidites. These rocks contain cratonal, well-sorbed subarkosic and quartzose sand and silt in part derived from the Canadian Shield. This siliciclastic fraction is intimately mixed with arenaceous micritized skeletal material and peloids derived from an eastern carbonate platform represented by the Snaky Canyon Formation in east-central Idaho, an eastern facies of the Eagle Creek Member, Wood River Formation in the Boulder Mountains, and the Oquirrh Formation in the Deep Creek Mountains. Subsidence of the OWRB may have been caused by two phases (DesMoinesian and Wolfcampian to Leonardian) of crustal loading by continental margin tectonism to the west. An elevated rim separated the OWRB from coeval volcanogenic basins to the west. Earlier, Antler-age structures may have been reactivated. A new pulse of tectonism occurred in Leonardian to Guadalupian time as in most places carbonatic and phosphatic strata of the Leonardian to Guadalupian Park City and Phosphoria Formation overlie OWRB strata, with different geographic arrangement of basinal, slope, and shelf depocenters.

    The work reported here covers Budget Phase I of the project. The principal tasks in Budget Phase I are the Reservoir Analysis and Characterization Task and the Advanced Technology Definition Task. Completion of these tasks have enabled an optimum carbon dioxide (CO{sub 2}) flood project to be designed and evaluated from an economic and risk analysis standpoint. Field implementation of the project has been recommended to the working interest owner of the South Cowden Unit (SCU) and approval has been obtained. The current project has focused on reducing initial investment cost by utilizing horizontal injection wells and concentrating the project in the best productivity area of the field. An innovative CO{sub 2} purchase agreement (no take or pay requirements, CO{sub 2} purchase price tied to West Texas Intermediate crude oil price) and gas recycle agreements (expensing cost as opposed to large capital investments for compression) were negotiated to further improve project economics. A detailed reservoir characterization study was completed by an integrated team of geoscientists and engineers. The study consisted of detailed core description, integration of log response to core descriptions, mapping of the major flow units, evaluation of porosity and permeability relationships, geostatistical analysis of permeability trends, and direct integration of reservoir performance with the geological interpretation. The study methodology fostered iterative bidirectional feedback between the reservoir characterization team and the reservoir engineering/simulation team to allow simultaneous refinement and convergence of the geological interpretation with the reservoir model. The fundamental conclusion from the study is that South Cowden exhibits favorable enhanced oil recovery characteristics, particularly reservoir quality and continuity.

The principal Tasks in Budget Phase I included in this report are Reservoir Analysis and Characterization; Advanced Technical Studies; and Technology Transfer, Reporting and Project Management Activities for Budget Phase I. The principle Task in Budget Phase II included in this report is Field Demonstration. Completion of these tasks has enabled an optimum carbon dioxide (CO{sub 2}) flood project to be designed, economically evaluated, and implemented in the field. Field implementation of the project commenced during late 1995, with actual CO{sub 2} injection scheduled for start-up in mid-July, 1996. The current project has focused on reducing initial investment cost by utilizing horizontal injection wells and concentrating the project in the best productivity area of the field. An innovative CO{sub 2} purchase agreement (no take-or-pay provisions, CO{sub 2} purchase price tied to West Texas Intermediate (WTI) crude oil price) and gas recycle agreements (expensing costs as opposed to a large upfront capital investment for compression) were negotiated to further improve the project economics. The Grayburg-San Andres section had previously been divided into multiple zones based on the core study and gamma ray markers that correlate wells within the Unit. Each zone was mapped as continuous across the field. Previous core studies concluded that the reservoir quality in the South Cowden Unit (SCU) is controlled primarily by the distribution of a bioturbated and diagenetically-altered rock type with a distinctive {open_quotes}chaotic{close_quotes} texture. The {open_quotes}chaotic{close_quotes} modifier is derived from the visual effect of pervasive, small-scale intermixing of tan oil-stained reservoir rock with tight gray non-reservoir rock.
