Foraging ecology of wintering wading birds along the Gulf of Mexico coast  

E-Print Network (OSTI)

I studied flock composition, distribution and foraging ecology of wintering wading birds along the Gulf of Mexico coast. I focused on geographic variability in wintering wading bird assemblages, the processes that structured these assemblages and habitat use by wading birds. I found considerable variation among three sites, Aransas National Wildlife Refuge (ANWR), Texas; Marsh Island Wildlife Refuge (MIWR), Louisiana; and Chassahowitzka National Wildlife Refuge (CNWR), Florida. Species comprising wintering wading bird assemblages varied regionally. ANWR had the most species-rich assemblage, with eight species. MIWR had only six wading bird species. And CNWR had only three different species. Processes that structured wintering wading bird assemblages also varied regionally. In ANWR, Texas, the Random Fraction niche apportionment model (RF model) best explained the empirical abundance data for ANWR. For abundance data from MIWR a good fit was obtained with the MacArthur Fraction (MF) model and the Power Fraction (PF) models. None of the models fully explained the CNWR abundance data. I also examined patterns of habitat partitioning among wintering wading birds at three different scales at two sites, Matagorda Island National Wildlife Refuge (MINWR) and Laguna Atascosa National Wildlife Refuge (LANWR). At the macrohabitat level, wintering wading birds showed interspecific differences in macrohabitat use of both open water habitats and vegetated flats. At the mesohabitat level all species at MINWR used the category nearest the edge most often, alternatively, at LANWR wading birds were most often in the mesohabitat category of 8.1- 12 m. from the edge. In both locations wading birds partitioned habitat based on water depth. Finally, I found that Great Egrets and Snowy Egrets participated more often in flock foraging and derived more benefits from feeding in flocks than other species. Great Egrets feeding in flocks had a higher mean strike rate than those foraging alone, whereas Snowy Egrets had a higher success rate foraging in flocks than those foraging alone. In the case of the darkercolored species (e.g., Great Blue Herons, etc.) they either showed no difference in behaviors between birds foraging in flocks versus those foraging alone or they actually did worse when they foraged in flocks.

A climatology of springtime convection systems over the Northwest Gulf of Mexico and adjacent coasts  

E-Print Network (OSTI)

A Springtime (March 15-June 15) climatology of Mesoscale Convective Systems (MCS) has been established on the basis of satellite imagery and radar reflectivities over the Northwest Gulf of Mexico and adjacent coastal areas during 1985-1994. The systems are tracked using hourly to half-hourly GOES-7 enhanced infrared satellite imagery. After tracking the storm's upper level cloud shield, radar reflectivities were used to classify the organization of convection within the MCS. The nine primary classes of convective structure were enhanced stratiform rain, embedded unorganized storms, unorganized storms, organized cells, solid line, symmetric line, asymmetric line, multiple convective bands, and embedded line. An examination was performed of the relationship between the synoptic-scale environment with the structure and evolution of these storms. Particular attention was given to synoptic-scale factors that affect convective organization. Climatological attributes such as diurnal characteristics and average durations were extracted from a documentation of more than 3@O meso-systems. Also, severe weather produced by the MCSs was examined. In addition, wind shear and thermodynamic parameters were analyzed during the initial phases of storm development. Since a climatological study has never been recorded for this region, the analysis will be informative for determining what type of interactions there are between synoptic scale forcing and mesoscale weather features in this area. Comparison with similar climatologies conducted in the Central Plains of the US was made to determine if MCS activity in a semi-tropical location was similar to that in more northern latitudes. Moreover, this radar climatology may be used as a resource in the planning of field experiments or operations concerning mesoscale weather throughout the southern portion of the US.

Gulf Coast Distillate Production  

Gasoline and Diesel Fuel Update (EIA)

4 of 15 4 of 15 Notes: PADD 3 is a major source of supply for the East Coast. This graph shows how during the winter of 1997-1998 when distillate stocks were very high, production fell back. In contrast, we entered the winter of 1996-1997 with very low stocks, and refineries reached record production levels as they tried to build stocks late in the season. Notice that production is normally reduced in January as distillate stocks are used to meet demand and as refineries begin maintenance and turnovers, which continue into February. This January is no different. There is room for some production increases in January and February, if refineries postpone maintenance. But postponing maintenance and turnarounds can create problems when the gasoline production season begins in March and April.

Regional Refinery Utilization Shows Gulf Coast Pressure  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: But there is some room for hope. Refineries generally begin maintenance in February or March, and finish in April. The East Coast was experiencing some lengthy refinery maintenance outages, as shown by the drop in utilization that remained low in most of March and April. In the meantime, the East Coast was drawing on extra supplies from the Gulf Coast and imports. The Midwest refineries seem to have been ramping up in April as they finished what maintenance was needed. But the Midwest no longer has the Blue Island refinery, so it also is pulling more product from the Gulf Coast. The high Gulf Coast prices this spring reflect extra "pull" on product from both the Midwest and the East Coast, and probably from California as well. Inputs into Gulf Coast refineries over the last 4 weeks

A wide-field imaging study with interference filters has revealed 35 new Herbig-Haro objects in the Gulf of Mexico. A grism survey has identified 41 Halpha emission-line stars, 30 of them new. A small cluster of partly embedded pre-main sequence stars is located around the known LkHalpha 185-189 group of stars, which includes the recently erupting FUor HBC 722.

Hypoxia in the Northern Gulf of Mexico  

Science Conference Proceedings (OSTI)

Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot support marine life, generally manifests itself in the spring. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. Since 2001, the hypoxic zone has averaged 16,500 km{sup 2} during its peak summer months, an area slightly larger than the state of Connecticut, and ranged from a low of 8,500 km{sup 2} to a high of 22,000 km{sup 2}. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together representatives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Office of Science and Technology Policy to conduct a scientific assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR). In 2000 the CENR completed An Integrated Assessment: Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment), which formed the scientific basis for the Task Force's Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico (Action Plan, 2001). In its Action Plan, the Task Force pledged to implement ten management actions and to assess progress every 5 years. This reassessment would address the nutrient load reductions achieved, the responses of the hypoxic zone and associated water quality and habitat conditions, and economic and social effects. The Task Force began its reassessment in 2005. In 2006 as part of the reassessment, USEPA's Office of Water, on behalf of the Task Force, requested that the U.S. Environmental Protection Agency (USEPA) Science Advisory Board (SAB) convene an independent panel to evaluate the state-of-the-science regarding hypoxia in the Northern Gulf of Mexico and potential nutrient mitigation and control options in the Mississippi-Atchafalaya River basin (MARB). The Task Force was particularly interested in scientific advances since the Integrated Assessment and posed questions in three areas: characterization of hypoxia; nutrient fate, transport and sources; and the scientific basis for goals and management options. The Hypoxia Study Group began its deliberations in September of 2006 and completed its report in August of 2007 while operating under the 'sunshine' requirements of the Federal Advisory Committee Act, which include providing public access to advisory meetings and opportunities for public comment. This Executive Summary summarizes the Hypoxia Study Group's major findings and recommendations.

Northern Gulf of Mexico Continental Shelf Stock  

E-Print Network (OSTI)

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

Improved recovery from Gulf of Mexico reservoirs  

Science Conference Proceedings (OSTI)

The Gulf of Mexico Basin offers the greatest near-term potential for reducing the future decline in domestic oil and gas production. The Basin is less mature than productive on-shore areas, large unexplored areas remain, and there is great potential for reducing bypassed oil in known fields. Much of the remaining oil in the offshore is trapped in formations that are extremely complex due to intrusions Of salt domes. Recently, however, significant innovations have been made in seismic processing and reservoir simulation. In addition, significant advances have been made in deviated and horizontal drilling technologies. Effective application of these technologies along with improved integrated resource management methods offer opportunities to significantly increase Gulf of Mexico production, delay platform abandonments, and preserve access to a substantial remaining oil target for both exploratory drilling and advanced recovery processes. On February 18, 1992, Louisiana State University (the Prime Contractor) with two technical subcontractors, BDNL Inc. and ICF, Inc., began a research program to estimate the potential oil and gas reserve additions that could result from the application of advanced secondary and enhanced oil recovery technologies and the exploitation of undeveloped and attic oil zones in the Gulf of Mexico oil fields that are related to piercement salt dornes. This project is a one year continuation of this research and will continue work in reservoir description, extraction processes, and technology transfer. Detailed data will be collected for two previously studied reservoirs: a South Marsh Island reservoir operated by Taylor Energy and a South Pelto reservoir operated by Mobil. This data will include reprocessed 2-D seismic data, newly acquired 3-D data, fluid data, fluid samples, pressure data, well test data, well logs, and core data/samples. Geologic data is being compiled; extraction research has not begun.

Identification of geopressured occurrences outside of the Gulf Coast  

DOE Green Energy (OSTI)

Methane dissolved in saline formation waters under abnormally high pressure (geopressure) is one of several unconventional gas sources that is under intensive investigation by the Department of Energy. The most well-known and studied region of geopressures in the US is the Gulf Coast geosyncline. Recent studies, however, indicate that this phenomenon is displayed in many other sedimentary basins encompassing lithologies and sedimentary environments unlike those of the Gulf Coast. These include various Rocky Mountain and Mid-Continent basins, onshore and offshore Californian, Alaskan and Pacific Coast basins, and other isolated occurrences. Of this group, two prime target areas, based on the indicated methane content of geopressured formation waters, would include the Cambrian sands of the Rome trough in West Virginia and selected Miocene sediments along the west side of the San Joaquin Valley in California.

This report presents the results of the Gulf of Mexico Regional Collaborative (GoMRC), a year-long project funded by NASA. The GoMRC project was organized around end user outreach activities, a science applications team, and a team for information technology (IT) development. Key outcomes are summarized below for each of these areas. End User Outreach ? Successfully engaged federal and state end users in project planning and feedback ? With end user input, defined needs and system functional requirements ? Conducted demonstration to End User Advisory Committee on July 9, 2007 and presented at Gulf of Mexico Alliance (GOMA) meeting of Habitat Identification committee ? Conducted significant engagement of other end user groups, such as the National Estuary Programs (NEP), in the Fall of 2007 ? Established partnership with SERVIR and Harmful Algal Blooms Observing System (HABSOS) programs and initiated plan to extend HABs monitoring and prediction capabilities to the southern Gulf. ? Established a science and technology working group with Mexican institutions centered in the State of Veracruz. Key team members include the Federal Commission for the Protection Against Sanitary Risks (COFEPRIS), the Ecological Institute (INECOL) a unit of the National Council for science and technology (CONACYT), the Veracruz Aquarium (NOAA’s first international Coastal Ecology Learning Center) and the State of Veracruz. The Mexican Navy (critical to coastal studies in the Southern Gulf) and other national and regional entities have also been engaged. ? Training on use of SERVIR portal planned for Fall 2007 in Veracruz, Mexico Science Applications ? Worked with regional scientists to produce conceptual models of submerged aquatic vegetation (SAV) ecosystems ? Built a logical framework and tool for ontological modeling of SAV and HABs ? Created online guidance for SAV restoration planning ? Created model runs which link potential future land use trends, runoff and SAV viability ? Analyzed SAV cover change at five other bays in the Gulf of Mexico to demonstrate extensibility of the analytical tools ? Initiated development of a conceptual model for understanding the causes and effects of HABs in the Gulf of Mexico IT Tool Development ? Established a website with the GoMRC web-based tools at www.gomrc.org ? Completed development of an ArcGIS-based decision support tool for SAV restoration prioritization decisions, and demonstrated its use in Mobile Bay ? Developed a web-based application, called Conceptual Model Explorer (CME), that enables non-GIS users to employ the prioritization model for SAV restoration ? Created CME tool enabling scientists to view existing, and create new, ecosystem conceptual models which can be used to document cause-effect relationships within coastal ecosystems, and offer guidance on management solutions. ? Adapted the science-driven advanced web search engine, Noesis, to focus on an initial set of coastal and marine resource issues, including SAV and HABs ? Incorporated map visualization tools with initial data layers related to coastal wetlands and SAVs

BOTTLENOSE DOLPHIN (Tursiops truncatus): Northern Gulf of Mexico Oceanic Stock  

E-Print Network (OSTI)

Thirty-eight stocks have been provisionally identified for Gulf of Mexico bottlenose dolphins (Waring et al. 2001). Gulf of Mexico inshore habitat has been separated into 33 bay, sound and estuarine stocks. Three northern Gulf of Mexico coastal stocks include nearshore waters from the shore to the 20 m isobath. The continental shelf stock encompasses waters from 20 to 200 m deep. The Gulf of Mexico oceanic stock encompasses the waters from the 200 m isobath to the seaward extent of the U.S. Exclusive Economic Zone (EEZ; Figure 1). Both “coastal/nearshore ” and “offshore ” ecotypes of bottlenose dolphins (Hersh and Duffield 1990) occur in the Gulf of Mexico (LeDuc and Curry 1998). The offshore and nearshore ecotypes are genetically distinct using both mitochondrial and nuclear markers (Hoelzel et al. 1998). In the northwestern Atlantic, Torres et al. (2003) found a statistically significant break in the distribution of the ecotypes at 34 km from shore. The offshore ecotype was found exclusively seaward of 34 km and in waters deeper than 34 m. Within 7.5 km of shore, all animals were of the coastal ecotype. If the distribution of ecotypes found by Torres et al. (2003) is similar in the northern Gulf of Mexico, the oceanic stock consists of the offshore ecoptype. Based on research currently being conducted on bottlenose dolphins in the Gulf of Mexico, as well as the western North Atlantic Ocean, the structure of these stocks is uncertain, but appears to be complex. The multi-disciplinary research programs conducted over the last two decades (e.g., Wells 1994) are beginning to shed light on stock structures of bottlenose dolphins, though additional analyses are needed before stock structures can be elaborated on in the Gulf of Mexico. As research is completed, it may be necessary to revise all the stocks of bottlenose dolphins in the Gulf of Mexico.

At the end of 2009, the GOM Fed accounted for close to one-fifth of oil proved reserves (second only to Texas) and just over four percent of natural gas proved reserves (the country's seventh largest reporting region). 1 Natural gas proved reserves from the GOM Fed have gradually diminished, both volumetrically and as a percentage of overall U.S. proved reserves. The latter is especially true in recent years as onshore additions (particularly those associated with shale gas activity) have increased considerably. Proved oil reserves from

Gulf of Mexico numerical model. Project summary  

DOE Green Energy (OSTI)

An efficient three-dimensional, time dependent prognostic model of the Gulf of Mexico has been developed. The model is driven by winds and surface heat flux derived from climatological, atmospheric surface data, the result of an intensive data analysis study. Mean velocity, temperature, salinity, turbulence kinetic energy and turbulence macroscale are the prognostic variables. Lateral boundary conditions for temperature and salinity and geostrophically derived velocity at the Straits of Yucatan and Florida are obtained from climatological ocean data. An analytical second moment turbulence closure scheme embedded within the model provides realistic surface mixed layer dynamics. Free surface elevation distributions are calculated with an algorithm which calculates the external (tidal) mode separately from the internal mode. The external mode, an essentially two-dimensional calculation, requires a short integrating timestep whereas the more costly, three-dimensional, internal mode can be executed with a long step. The result is a fully three-dimensional code which includes a free surface at no sacrifice in computer cost compared to rigid lid models.

Identification of geopressured occurrences outside of the Gulf Coast. Final report, Phase I  

DOE Green Energy (OSTI)

As an extension of its efforts in the development of the geopressured resources of the Gulf Coast, the Division of Geothermal Energy of the US Department of Energy is interested in determining the extent and characteristics of geopressured occurrences in areas outside the Gulf Coast. The work undertaken involved a literature search of available information documenting such occurrences. Geopressured reservoirs have been reported from various types of sedimentary lithologies representing virtually all geologic ages and in a host of geologic environments, many of which are unlike those of the Gulf Coast. These include many Rocky Mountain basins (Green River, Big Horn, Powder River, Wind River, Uinta, Piceance, Denver, San Juan), Mid-Continent basins (Delaware, Anadorko, Interior Salt, Williston, Appalachian), California basins (Sacramento, San Joaquin, Los Angeles, Ventura, Coast Ranges), Alaskan onshore and offshore basins, Pacific Coast offshore basins, and other isolated occurrences, both onshore and offshore.

Steerable motor systems in the Gulf of Mexico  

SciTech Connect

Since their introduction to the Gulf of Mexico in September 1985, downhole steerable motor systems have been widely recognized for making major contributions to improved directional and horizontal drilling efficiency as well as the overall advancement of drilling technology. Some sources estimate this advanced technology can improve overall drilling productivity by 50 percent. Others foresee the day when future generations of the current systems will replace the rotary table as the primary drive mechanisms for the bit. While the technological issues are coming into better focus, less visible are the ripple effects of this innovation upon the market participants who supply traditional products and services complimentary to the drilling process. The purpose of this article is to provide an objective evaluation of the performance statistics of steerable motor systems to date in the Gulf of Mexico, thereby allowing for a greater understanding of the future market conditions that may develop with this emerging technology.

A chronostratigraphic framework for the northwestern slope of the gulf of mexico  

E-Print Network (OSTI)

Sediments from two cores, JPC31 and JPC46, were analyzed to better understand the relationship between climate and sediment deposition on the continental slope of the northwestern Gulf of Mexico. These two cores were selected from a suite of cores collected from the slope of the Gulf of Mexico after examining how bulk density varied with depth in the cores. The presence/absence of Globoratalia menardii, down-core variations of the 18O of Globigerinoides ruber, tephrochronology, and radiocarbon dating of G. ruber were used to determine the chronologies of the sediments in the cores. Globorotalia menardii were present until a depth of 100 cm in JPC31. The entrance of G. menardii in the Gulf of Mexico was dated at 8 kyr. Analysis of an ash layer found in both JPC31 and 46 yielded a date of 84 kyr, at depths of 700 cm and 1440 cm, respectively. Radiocarbon dating yielded four ages in JPC31. In sediment core JPC31, Marine Isotope Stage (MIS) 1-5 were recorded. In sediment core JPC46, MIS 2-4 and a portion of MIS 5 were recorded. These results provide a framework for determining general sedimentation rates from the northwestern slope of the Gulf of Mexico. Events in the density profiles in JPC31 and JPC46 were correlated to corresponding events in the rest of the slope cores, allowing the chronologies of JPC31 and JPC46 to be transferred to the suite of the slope cores. Sedimentation rates along different portions of the slope were then calculated, and variations in these sedimentation rates were used to better understand slope sedimentary processes. Sedimentation rates on the northwestern slope of the Gulf of Mexico were calculated for the most recent 120,000 years and compared with climate to deduce trends. Sedimentation rates for MIS 1-5 ranged from 7 cm/kyr to 28 cm/kyr. The sedimentation rate for the last glaciation (MIS 2, 3, and 4) were the highest for the time interval studied. The lowered sea level during glacial advances brings sediments farther out onto the slope; therefore, a higher sedimentation rate is expected during this time. These rates varied from 22 cm/kyr near the coast to 7 cm/kyr toward the abyssal plains. Of the 12 cores analyzed along the slope, JPC23 and JPC24 had the lowest sedimentation rates. This is likely due to high density bottom currents and turbidity currents which carry sediments farther out on the slope. Therefore, the lowest sedimentation rates would be expected a great distance from the land mass and some distance from the abyssal plains.

Economics of producing methane (exclusively) from geopressured aquifers along the Gulf Coast  

SciTech Connect

The purpose of this report was to estimate the cost of producing methane (natural gas) from geopressured aquifers inland from and along the coast of the Gulf of New Mexico. No other economic values of the geopressured brines were considered for exploitation. There were several component tasks of such an overall analysis which had to be completed in order to arrive at the final conclusion. (1) An estimate of the reservoir parameters of the geopressured aquifers; their areal extent, net thickness of productive sand, porosity, permeability, effective compressibility. It is these parameters which determine the production rates and the total recovery of the resource that may be expected within an economic time frame. (2) An estimate of the production rates and cumulative production of geopressured aquifers having reservoir properties falling into the range of values that may be anticipated from the results of the first task. (3) An estimate of the operating and capital costs of drilling wells and producing such geopressured aquifers, integral and significant part of the operating costs is the cost of disposing of the large quantities of produced brines following the desorption of the methane. (4) An estimate of the sales price of the recovered methane using appropriate discount rates.

Predicted impacts from offshore produced water discharges on hypoxia in the Gulf of Mexico.  

SciTech Connect

Summer hypoxia (dissolved oxygen < 2 mg/L) in the bottom waters of the northern Gulf of Mexico has received considerable scientific and policy attention because of potential ecological and economic impacts. This hypoxic zone forms off the Louisiana coast each summer and has increased from an average of 8,300 km{sup 2} in 1985-1992 to over 16,000 km{sup 2} in 1993-2001, reaching a record 22,000 km{sup 2} in 2002. The almost threefold increase in nitrogen load from the Mississippi River Basin (MRB) to the Gulf since the middle of the last century is the primary external driver for hypoxia. A goal of the 2001 Federal Action Plan is to reduce the 5-year running average size of the hypoxic zone to below 5,000 km{sup 2} by 2015. After the Action Plan was developed, a new question arose as to whether sources other than the MRB may also contribute significant quantities of oxygen-demanding substances. One very visible potential source is the hundreds of offshore oil and gas platforms located within or near the hypoxic zone, many of which discharge varying volumes of produced water. The objectives of this study were to assess the incremental impacts of produced water discharges on dissolved oxygen in the northern Gulf of Mexico, and to evaluate the significance of these discharges relative to loadings from the MRB. Predictive simulations were conducted with three existing models of Gulf hypoxia using produced water loads from an industry study. Scenarios were designed that addressed loading uncertainties, settleability of suspended constituents, and different assumptions on delivery locations for the produced water loads. Model results correspond to the incremental impacts of produced water loads, relative to the original model results, which included only loads from the MRB. The predicted incremental impacts of produced water loads on dissolved oxygen in the northern Gulf of Mexico from all three models were small. Even considering the predicted ranges between lower- and upper-bound results, these impacts are likely to be within the errors of measurement for bottomwater dissolved oxygen and hypoxic area at the spatial scale of the entire hypoxic zone.

Oxygen and Carbon Isotopes and Coral Growth in the Gulf of Mexico and Caribbean Sea as Environmental and Climate Indicators  

E-Print Network (OSTI)

The Gulf of Mexico and Caribbean Sea comprise a sensitive and important region, both oceanographically and climatically. A better understanding of the history of climate and marine environmental conditions in this region provides valuable insight into the processes that affect climate globally. This dissertation furthers our understanding of these factors via investigations of the isotopes of corals and seawater, as well as coral growth. Results improve our understanding of how the isotope and coral growth records from the Gulf of Mexico and Caribbean Sea reflect recent environmental conditions, enhancing our ability to reconstruct the history of climate in this important region. Analysis of the relationship between salinity and oxygen isotopic composition of seawater from the Texas/Louisiana continental shelf and Flower Garden Banks yield improved understanding of the relative contribution of the fresh water sources into the northern Gulf of Mexico, and also the oxygen isotopic composition of open-ocean seawater in this region. Variations in the growth of long-lived coral cores from the Flower Garden Banks are compared to local and regional climate conditions, particularly winter air temperatures. During the latter half of the twentieth century, a close correlation has existed between slow coral growth and cold wintertime air temperatures along the Gulf Coast, which are due to a meridional orientation of the North American jet stream (associated with the Pacific/North American climate pattern). Existing long coral growth records are too limited to assess this relationship during earlier years. Knowledge of the marine radiocarbon (14C) reservoir age is important for understanding carbon cycling and calibrating the radiocarbon ages of marine samples. Radiocarbon concentrations in corals from the Flower Garden Banks, Veracruz, and the Cariaco Basin are measured and used to determine the surface ocean 14C reservoir ages for the Gulf of Mexico and Caribbean Sea. Results also indicate that the post-nuclear weapons testing Delta 14-C values of the Gulf of Mexico and Caribbean Sea differ. This difference is attributed to the advection of 14C-depleted surface water from the Southern Hemisphere into the Caribbean Sea. The results reported in this dissertation provide valuable information for understanding the marine environment when using carbonate proxies to study and reconstruct past climate and marine conditions in the Gulf of Mexico and Caribbean.

How Pemex will develop Campeche Sound. [Gulf of Mexico  

Science Conference Proceedings (OSTI)

While many OPEC nations are cutting production in the current so-called ''oil glut '', Mexico is moving at top speed to increase oil and gas production - principally the light crude from Campeche Sound. To boost output from the Gulf of Mexico oil giant, Pemex is drilling 54 development wells and installing 29 platforms in Campeche this year. Seven of the platforms will handle the growing gas production, where Pemex has been flaring 500 MMcfd of gas offshore. This gas will be moved ashore via 47 platforms and 36-in-dia pipe lines now being installed. Two of the seven gas platforms now being installed are among the world's largest. They are designed to handle 400 MMcfd of gas each - twice the capacity of the largest gas platforms operating in the North Sea.

Factors Shaping Macrofaunal Polychaete Communities in the Gulf of Mexico  

E-Print Network (OSTI)

This dissertation addresses large-scale trends in composition, density, taxonomic and functional diversity in deep-sea benthic polychaete communities in the Gulf of Mexico (GoM). The study includes samples from two major sampling programs: the Deep Gulf of Mexico Benthos (DGoMB) program (2000–2002) (51 stations, 200-3700 m) and the SIGSBEE program (Universidad Nacional Autónoma de México), 2008-2010 (27 stations on the Sigsbee Abyssal Plain). Polychaete density decreased exponentially with depth. Alpha diversity did not show a mid-depth maximum and reached its peak near the Mississippi trough. Feeding guild diversity was also highest in the Mississippi trough. The environmental parameters that determine diversity and density of polychaete assemblages and species distribution ranges were examined. Depth, export flux of particulate organic carbon (POC), percent sand and silt were the best predictors of heterogeneity of polychaetes in the GoM. We performed an ecological niche modeling analysis (ENM) based on ‘presence-only’ data of four cosmopolitan species belonging to the Cirratulidae and Spionidae in the GoM. The GoM, being a semi-enclosed ocean basin, offers complex topographic features and hydrographic processes. Comparisons of the overall polychaete diversity and richness patterns from this study for this region indicate a strong geographic variation with increasing depth and distance from the shore. Additionally, the environmental gradients observed play a major role in shaping the spatial distribution of polychaete communities in this region.

SciTech Connect

If 1996 trends continue, exploration and development will flourish in the Gulf of Mexico this year and for many years to come. Able to drill and complete wells in steadily deeper water, and propelled by rising prices for oil and gas, operators are advancing projects throughout the Gulf. The activity is expected to nearly double oil production from the Gulf of Mexico in the next 10 years. The paper discusses targets, technology, activity indicators, operator alliances, specific fields, subsalt production and plans, transportation, Gulf role and outlook.

Sandstone consolidation analysis to delineate areas of high-quality reservoirs suitable for production of geopressured geothermal energy along the Texas Gulf Coast  

DOE Green Energy (OSTI)

Analysis of reservoir quality of lower Tertiary sandstones along the Texas Gulf Coast delineates areas most favorable for geopressured geothermal exploration. Reservoir quality is determined by whole core, acoustic log, and petrographic analyses. The Wilcox Group has good reservoir potential for geopressured geothermal energy in the Middle Texas Gulf Coast and possibly in adjacent areas, but other Wilcox areas are marginal. The Vicksburg Formation in the Lower Texas Gulf Coast is not prospective. Reservoir quality in the Frio Formation increases from very poor in lowermost Texas, to marginal into the Middle Texas Gulf Coast and to good through the Upper Texas Gulf Coast. The Frio Formation in the Upper Texas Gulf Coast has the best deep-reservoir quality of any unit along the Texas Gulf Coast. (MHR)

SNG completes deepest underwater pipelay in Gulf of Mexico  

SciTech Connect

This paper reports that gas began flowing this spring in the deepest underwater, large-diameter pipeline in the U.S. Gulf of Mexico. Water depth along the route of the pipeline varies from approximately 460 ft at the Alabaster platform, increasing to the record depth of 1,220 ft in the Mississippi Canyon area, and decreasing to negligible water depth at the landfall site southwest of Venice. The SNG Mississippi Canyon Block 397 pipeline project exemplifies how a pipeline project can encounter an array of conditions which prompt special design considerations and installation techniques. Important considerations for this project were related to pipe properties, anti-corrosion and weight coatings, span and buckle considerations, and installation equipment. A team effort was used to study, research, test, design, and install this pipeline.

Barrier island evolution and reworking by inlet migration along the Mississippi-Alabama gulf coast  

SciTech Connect

The five barrier islands along the Mississippi-Alabama coast are located 10 to 14 mi (16 to 23 km) offshore and separate Mississippi Sound from the Gulf of Mexico. The barrier islands in the chain are, from east to west: Dauphin Island, Petit Bois Island, Horn Island, Ship Island, and Cat Island. The islands are low sand bodies situated on a relatively broad Holocene sand platform that extends 70 mi (113 km) from Dauphin Island on the east to Cat Island on the west. The platform varies in thickness from 25 to 75 ft (7.6 to 23 m) and rests on Holocene marine clays or on Pleistocene sediments. The barrier island chain predates the St. Bernard lobe of the Mississippi delta complex, which began to prograde about 3,000 years ago, and continued until it was abandoned approximately 1,500 years ago. In contrast to the other islands, Cat Island at the western down-drift end of the Mississippi-Alabama barrier island chain is characterized by more than 12 prominent east west-oriented progradational linear ridges. The ridge system of Cat Island is interpreted as a relict of an earlier stage in the life cycle of the barrier platform when there was a more robust littoral drift system and an abundant sediment supply During the Pre-St. Bernard Delta period of vigorous sedimentation, all of the islands in the barrier chain probably exhibited progradational ridges similar to those now found only on Cat Island. Presently, only vestigial traces of these progradational features remain on the islands to the east of Cat Island. Unlike Cat Island, which has been protected and preserved by the St. Bernard Delta, the other barrier islands have been modified and reworked during the past 1,500 years by processes of island and tidal inlet migration, accompanied by a general weakening of the littoral drift and a reduction of the available sediment supply.

DOE Green Energy (OSTI)

The site chosen for study off the western coast of Mexico between 20--23/sup 0/ North latitude, 105--110/sup 0/ West longitude has a temperature difference resource which is more than adequate for potential OTEC use. The annual mean ..delta..T to 1000 meters is 20.9/sup 0/C. An annual mean ..delta..T of 20.0/sup 0/C is available at 800 meters. The monthly mean ..delta..T for the coldest month of the year is 17.2/sup 0/C; at 800 meters while there is some variation in the monthly mean temperature difference, even the coldest month is adequate. The mixed layer depth is very shallow throughout the entire year. Storms are a problem for this area between May and November. Low sea and swell predominate throughout the year. The surface currents are generally weak to moderate with some variation in direction during the year. The continental shelf is fairly wide for most of the region making the distance to shore from depths of 1000 meters somewhat large. There is one bay from which deep water can be reached within 5 kilometers.

Mercury Contamination in Pelagic Fishes of the Gulf of Mexico  

E-Print Network (OSTI)

Knowledge of mercury concentrations in fish is essential for human health protection. Mercury is a naturally occurring element that acts as a neurotoxin to humans and other species. The biologically available mercury form, methylmercury (MeHg), bio accumulates from small benthic invertebrates to large pelagic fish, and therefore high end consumers and terminal predators have elevated Hg concentrations. The main pathway of MeHg exposure in humans is by consumption of contaminated fish. In this study total Hg concentrations were measured in 10 Gulf of Mexico pelagic fish species using a DMA 80 analyzer. Total Hg concentrations ranged from 0.004 to 3.55 ppm (wet wt). The highest mean concentration (1.04 ppm, wet wt) recorded in king mackerel (Scomberomorus cavalla) exceeded FDA recommended criteria of 1ppm. Dolphinfish (Coryphaena hippurus) and vermilion snapper (Rhomboplites aurorubens) had lowest mean Hg concentrations (tuna (Thunnus atlanticus) and yellowfin tuna (Thunnus albacores) had moderate Hg concentrations (0.39 and 0.36 ppm wet wt respectively). Little tunny (Euthynnus alletteratus) and blacktip shark (Carcharhinus limbatus) had mean concentrations of 0.69 and 0.51 ppm respectively. The relationship between fish length and Hg concentrations was significant for four species.

Coring unconsolidated sands in the Gulf of Mexico  

SciTech Connect

Diamant Board Stratabit has achieved coring recovery rates in soft, unconsolidated formations as high as 99 percent. These rates are achieved using conventional coring equipment in a special configuration to minimize frictional resistance to the core as it passes through the bit and core catcher assembly and enters the inner barrel. This paper describes DBS's coring experience with its Maximum Core Protection System, which has been used at depths from 3000 ft to below 20,000 ft and in deviated holes up to 57 degrees. In the Gulf of Mexico, the system cored over 5800 ft from Matagorda Island to Charlotte Harbor, with an overall recovery rate of 93 percent. In most applications, the hole size dictates the core barrel and core size. Through 9 5/8-in. casing with an 8 1/2-in. by 4-in. core bit, the 6 3/4-in. by 4-in. by 30-ft conventional core barrel will be used with a Fibertube inner barrel to replace the steel inner barrel, allowing a full 4-in. core to be cut. In smaller hole sizes, other equipment with the Maximum Core Protection System will be used. With a top drive unit or long Kelly, a 45-ft or 60-ft barrel may be used. Many times an unconsolidated formation will not support more than 30 ft of core, therefore 30-ft barrels are normally used.

Petroleum geology of the Gulf of California, Mexico  

Science Conference Proceedings (OSTI)

The Gulf of California basin proper is a very young (late Miocene) feature in northwestern Mexico, produced by the tectonic interaction of the Pacific and American plates. Sediments are mostly siliciclastic with thicknesses that may exceed 8,000 m (26,248 ft). Exploratory drilling started in 1979 and since then, ten offshore and seven onshore wells have been spudded. Foremost among the former the Extremeno 1 well tested from a thin deltaic sand 4,115 m deep (13,501 ft) a daily flow of 6.2 million ft{sup 3} of gas and 130 bbl of gas condensate through a 0.25 in. choke with a pressure of 280 kg/cm{sup 2} (3,981 psi). In the southern part of the basin, the offshore Huichol 1 well was also a gas and condensate producer, albeit noncommercial. Geologically, the basin's favorable generation and trapping conditions make up a very attractive scenario for a future petroleum producing province, once exploration priorities are considered timely.

Environmental Assessment: Geothermal Energy Geopressure Subprogram. Gulf Coast Well Testing Activity, Frio Formation, Texas and Louisiana  

DOE Green Energy (OSTI)

This Environmental Assessment (EA) has been prepared to provide the environmental input into the Division of Geothermal Energy's decisions to expand the geothermal well testing activities to include sites in the Frio Formation of Texas and Louisiana. It is proposed that drilling rigs be leased before they are removed from sites in the formation where drilling for gas or oil exploration has been unsuccessful and that the rigs be used to complete the drilling into the geopressured zone for resource exploration. This EA addresses, on a regional basis, the expected activities, affected environment, and the possible impacts in a broad sense as they apply to the Gulf Coast well testing activity of the Geothermal Energy Geopressure Subprogram of the Department of Energy. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay, Atlas) water at high temperatures and high pressures is trapped within Gulf basin sediments. The water is confined within or below essentially impermeable shale sequences and carries most or all of the overburden pressure. Such zones are referred to as geopressured strata. These fluids and sediments are heated to abnormally high temperatures (up to 260 C) and may provide potential reservoirs for economical production of geothermal energy. The obvious need in resource development is to assess the resource. Ongoing studies to define large-sand-volume reservoirs will ultimately define optimum sites for drilling special large diameter wells to perform large volume flow production tests. in the interim, existing well tests need to be made to help define and assess the resource.

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

E-Print Network (OSTI)

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

Risking fault seal in the Gulf Coast: A joint industry study  

SciTech Connect

Analysis of more than 200 faults in a joint-industry study of the Gulf Coast provides a database of actual fault seal behavior in producing fields. This empirical database demonstrates that fault seal behavior is predictable rather than random and that faults are more important than is commonly thought in controlling hydrocarbon accumulations. Quantitative fault seal analysis demonstrates that seal behavior is empirically related to the amount of sand and shale incorporated in the fault zone. Faults with sand-rich gouge leak. Faults with shale-rich gouge seal. An empirically defined threshold allows prediction of fault seal behavior with a high degree of confidence. Fewer than 10% of the faults in the Gulf Coast are exceptions to the rule. Exceptions are a result of other factors including low permeability and high displacement pressure sands, and thin-bedded sand/shale sequences. Examples from these Gulf Coast fields demonstrate the fundamental importance of faults in controlling hydrocarbon accumulations. Faults and fault seal behavior control the presence or absence of hydrocarbons, percent fill, hydrocarbon column heights, entrapment of oil versus gas, and high-side and low-side trap risk. Faults control the lateral distribution of hydrocarbon within fault compartments as well as the vertical distribution of hydrocarbon among stacked sands. Faults control fluid flow during both field development and hydrocarbon migration. Bypassed residual accumulations and unnecessary production wells result from neglecting routine fault seal analysis during field development. Dry holes and mistaken reserves assessments result from neglecting routine fault seal analysis during exploration.

Produced water discharges to the Gulf of Mexico: Background information for ecological risk assessments  

Science Conference Proceedings (OSTI)

This report reviews ecological risk assessment concepts and methods; describes important biological resources in the Gulf of Mexico of potential concern for produced water impacts; and summarizes data available to estimate exposure and effects of produced water discharges. The emphasis is on data relating to produced water discharges in the central and western Gulf of Mexico, especially in Louisiana. Much of the summarized data and cited literature are relevant to assessments of impacts in other regions. Data describing effects on marine and estuarine fishes, mollusks, crustaceans and benthic invertebrates are emphasized. This review is part of a series of studies of the health and ecological risks from discharges of produced water to the Gulf of Mexico. These assessments will provide input to regulators in the development of guidelines and permits, and to industry in the use of appropriate discharge practices.

Comparison of operational energy intensities and consumption of pipelines versus coastal tankers: US Gulf coast to northeast coast routes  

SciTech Connect

This report is a comparative analysis of operational energy intensities and consumption for pipeline shipments versus coastal tanker and tanker-barge movements of light petroleum products from the US Gulf Coast to US East Coast Mid-Atlantic states. It has been prepared for the Office of Transportation Programs of the US Department of Energy (DOE) as part of a project designed to develop energy conservation strategies in the areas of modal shifts and energy materials transport. It also answers an expressed interest of DOE's Office of Competition as to whether energy penalties are being paid in this region by the shipment of this oil by tanker rather than pipeline. Detailed estimates are made of the 1977 energy intensities (EIs) for tankers and the two major pipelines serving these routes; these are the Colonial pipeline (from Houston) and the Plantation pipeline (from Baton Rouge). Estimates of potential operational energy savings gained from diverting these shipments from tankers to pipelines are figured from these EIs plus 1977 tanker short-ton volumes for these products. Also estimated for these diversions are additional savings of petroleum available through shifts from the fuel oil used to power tankers, to the other energy sources used by pipelines (e.g., coal, which is burned by the utilities serving them). Table 1 indicates that these tanker volumes have been large and steady as a whole; however, individual origin ports have had substantial variations since the 1973 Arab oil embargo. Indirect energy requirements of the two modes are not included in this analysis because the methodology for calculating them is still an unresolved research area (e.g., diagreements exist as to how much supporting-infrastructure energy usage should be included for a mode).

Impacts from oil and gas produced water discharges on the gulf of Mexico hypoxic zone.  

Science Conference Proceedings (OSTI)

Shallow water areas of the Gulf of Mexico continental shelf experience low dissolved oxygen (hypoxia) each summer. The hypoxic zone is primarily caused by input of nutrients from the Mississippi and Atchafalaya Rivers. The nutrients stimulate the growth of phytoplankton, which leads to reduction of the oxygen concentration near the sea floor. During the renewal of an offshore discharge permit used by the oil and gas industry in the Gulf of Mexico, the U.S. Environmental Protection Agency (EPA) identified the need to assess the potential contribution from produced water discharges to the occurrence of hypoxia. The EPA permit required either that all platforms in the hypoxic zone submit produced water samples, or that industry perform a coordinated sampling program. This paper, based on a report submitted to EPA in August 2005 (1), describes the results of the joint industry sampling program and the use of those results to quantify the relative significance of produced water discharges in the context of other sources on the occurrence of hypoxia in the Gulf of Mexico. In the sampling program, 16 facilities were selected for multiple sampling - three times each at one month intervals-- and another 34 sites for onetime sampling. The goal of the sampling program was to quantify the sources and amount of oxygen demand associated with a variety of Gulf of Mexico produced waters. Data collected included direct oxygen demand measured by BOD5 (5-day biochemical oxygen demand) and TOC (total organic carbon) and indirect oxygen demand measured by nitrogen compounds (ammonia, nitrate, nitrate, and TKN [total Kjeldahl nitrogen]) and phosphorus (total phosphorus and orthophosphate). These data will serve as inputs to several available computer models currently in use for forecasting the occurrence of hypoxia in the Gulf of Mexico. The output of each model will be compared for consistency in their predictions and then a semi-quantitative estimate of the relative significance of produced water inputs to hypoxia will be made.

Geopressured geothermal fairway evaluation and test-well site location, Frio Formation, Texas Gulf Coast  

DOE Green Energy (OSTI)

Tertiary strata of the Texas Gulf Coast comprise a number of terrigenous depositional wedges, some of which thicken abruptly at their downdip ends as a result of contemporaneous movement of growth faults and underlying salt. The Frio Formation, one of these wedges, has been studied regionally by means of a grid of correlation cross sections aided by micropaleontological control. By means of these sections, the Frio was subdivided into six map units; maps of sandstone distribution within these units delineate principal elongate sandstone trends parallel to the Gulf Coast composed of deltaic, barrier-bar, and strandplain sandstones. These broad regional studies, followed by detailed local investigations, were pursued in order to delineate prospective areas for production of geopressured geothermal energy. A prospective area must meet the following minimum requirements; reservoir volume of 3 cubic miles, minimum permeability of 20 millidarcys (md), and fluid temperatures of 300/sup 0/F. Several geothermal fairways were identified as a result of this Frio study. In summary, detailed geological, geophysical, and engineering studies conducted on the Frio Formation have delineated a geothermal test well site in the Austin Bayou Prospect which extends over an area of 60 square miles. A total of 800 to 900 feet of sandstone will occur between the depths of 13,500 and 16,500 feet. At least 30% of the sand will have core permeabilities of 20 to 60 millidarcys. Temperature at the top of the sandstone section will be 300/sup 0/F. Water, produced at a rate of 20,000 to 40,000 barrels per day, will probably have to be disposed of by injection into shallower sandstone reservoirs. More than 10 billion barrels of water are in place in these sandstone reservoirs of the Austin Bayou Prospect; there should be approximately 400 billion cubic feed of methane in solution in this water.

Oil and gas developments in Louisiana Gulf Coast onshore in 1982  

Science Conference Proceedings (OSTI)

The south Louisiana Gulf Coast onshore area is composed of 38 parishes. Petroleum operators drilled 1,344 wells with a total footage of 15,670,916 ft, a 15% decline from the 1981 total of 1,578 wells. Operators in south Louisiana drilled 283 wildcat wells with a success rate of 11%, 328 other exploratory wells with a success rate of 29%, and 733 development wells with a success rate of 68%. Wildcat drilling discovered 12 significant new fields. These significant new discoveries consist of 5 fields producing from Miocene sands, 5 fields producing from Oligocene Frio or Hackberry sands, and 2 fields producing from Eocene Cockfield and Wilcox sands. For the first time in recent years, there was not a new field discovered within the state's famous Tuscaloosa trend. Operators acquired 1,005,464 acres of mineral leases, a 43% decline from the 1981 total of 1,766,536 acres. Leasing was most active in Lafourche, Calcasieu, Beauregard, Terrebonne, and Jefferson Davis Parishes. Arco led all major companies in acquiring leases in south Louisiana, and Florida Exploration was the most active independent operator. Geophysical activity in the onshore Louisiana Gulf Coast decreased for the first time since 1973. Activity dropped from the 1,734 crew-weeks in 1981 to 1,526 crew-weeks in 1982. The highest levels of geophysical activity were registered in Plaquemines, St. Landry, Terrebonne, Pointe Coupee, and Lafourche Parishes. For the third consecutive year, Arco led all operators in seismic activity in south Louisiana.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

SciTech Connect

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort was made to locate and retain the services of a suitable vessel and submersibles or Remotely Operated Vehicles (ROVs) following the storms and the loss of the contracted vessel, the M/V Ocean Quest and its two submersibles, but these efforts have been fruitless due to the demand for these resources in the tremendous recovery effort being made in the Gulf area. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA).

Classification of surficial sediments: North-Central and Eastern Gulf of Mexico  

E-Print Network (OSTI)

The surface sediments in the North-Central and Eastern Gulf of Mexico can be appropriately characterized by physical property analysis, especially by comparison of wet-bulk density. Two hundred and eighty, 1-5 meter cores have been collected on positive sea floor features in three physiographic regions in the Gulf of Mexico: the Intraslope Basin, Sigsbee Escarpment, and Mississippi Fan regions. Analysis found that using three independent calculations or approximations of wet-bulk density proved to reasonably identify distinct, surficial sediment characteristics for each of these three regions. After initial segregation into three density regimes, the cores were characterized based on analysis of p-wave velocity, porosity, impedance, void ratio, water content, shear strength and various observed physical properties such as grain-size, sediment structure, and color. The methods of characterization lead to the unique classification of surficial sediments in these physiographic regions.

Gulf Coast Programmatic Environmental Assessment Geothermal Well Testing: The Frio Formation of Texas and Louisiana  

DOE Green Energy (OSTI)

In accordance with the requirements of 10 CFR Part 711, environmental assessments are being prepared for significant activities and individual projects of the Division of Geothermal Energy (DGE) of the Energy Research and Development Administration (ERDA). This environmental assessment of geopressure well testing addresses, on a regional basis, the expected activities, affected environments, and possible impacts in a broad sense. The specific part of the program addressed by this environmental assessment is geothermal well testing by the take-over of one or more unsuccessful oil wells before the drilling rig is removed and completion of drilling into the geopressured zone. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay) water at high temperatures and high pressures is trapped within Gulf basin sediments. The water is confined within or below essentially impermeable shale sequences and carries most or all of the overburden pressure. Such zones are referred to as geopressured strata. These fluids and sediments are heated to abnormally high temperatures (up to 260 C) and may provide potential reservoirs for economical production of geothermal energy. The obvious need in resource development is to assess the resource. Ongoing studies to define large-sand-volume reservoirs will ultimately define optimum sites for drilling special large diameter wells to perform large volume flow production tests. In the interim, existing well tests need to be made to help define and assess the resource. The project addressed by this environmental assessment is the performance of a geothermal well test in high potential geothermal areas. Well tests involve four major actions each of which may or may not be required for each of the well tests. The four major actions are: site preparation, drilling a salt-water disposal well, actual flow testing, and abandonment of the well.

High-amplitude reflection packets (HARPs) of the Mississippi Fan, Gulf of Mexico  

E-Print Network (OSTI)

Examination of seismic data from the deep-water Gulf of Mexico reveals the presence of High-Amplitude Reflection Packets (HARPs). An analog study conducted by the Ocean Drilling Program Leg 155 identified and described Amazon Fan HARPs as a stacked, relatively unconfined series of graded turbidites overlain by a channel-levee. HARP seismic facies thin laterally and onlap antecedent bathymetry (preexisting submarine topography). HARP areal extent is controlled by antecedent bathymetry and turbidity flow sediment volumes. Mississippi Fan HARP deposition can be described by three depositional models: the "avulsion" model, the "fill and spill" model, and the "transition" model. The "avulsion" depositional model, developed by Flood et al. (1991), describes avulsion of submarine channel-levees by turbidity flows. Subsequent turbidity flows exit the channel-levee at the avulsion point and are deposited as unchannelized HARPs. The "fill and spill" model, developed by Satterfield and Behrens (1990), describes turbidite deposition in the Gulf of Mexico salt province. Initial stages of the "fill and spill" model accurately describe the seismic geometries of HARPs confined by adjacent salt structures. The "transition" model was developed in this study to describe the Gulf of Mexico HARP seismic geometries seen in the transition zone from the salt province to the abyssal plain. The HARPs described by the "transition" model contain an upslope segment confined by salt structures and a downslope segment confined by antecedent bathymetry. Utilizing seismic data from the Gulf of Mexico and core and well-log data from the Amazon Fan, this study has determined that HARPs and related channel-levees have hydrocarbon play potential. HARP sheet sands, internal HARP channel fill, overlying channel-levee fill, and overbank levee sands are potential reservoir units. Detrital carbonate and hemipelagic shale source rocks are in place in the deep-water Gulf of Mexico. In addition, structurally derived migration pathways combine with percolation as potential migration processes. This study integrates identification and description of HARP seismic facies relationships, current and newly developed depositional models, interpretation of stratigraphic controls, HARP internal reservoir architecture, and determination of HARP hydrocarbon potential in order to predict HARP deposition in the Mississippi Fan and other mud-rich fans worldwide.

Properties of geopressured brines and wells in the Gulf Coast and opportunities for industrial/research participation  

DOE Green Energy (OSTI)

Geopressured reservoirs exhibit pressure gradients in excess of the normal hydrostatic gradient. (In the Gulf Coast area the normal gradient is 0.465 psi/ft.) Pressures may approach lithostatic pressure and have been measured as high as 1.05 psi/ft in the Gulf Coast area. Geopressured basins exist worldwide and in a number of US locations, east, west, north and south. The Gulf Coast area has been studied extensively and is the subject of the DOE geopressured-geothermal research at present. Present industrial interest in the Pleasant Bayou and Hulin wells include: desalination plants, an economic study by a power company for regional use, use of generated electricity by a coalition of towns, aquaculture (catfish farming) research program, and an unsolicited proposal for enhanced oil recovery of heavy oil. Direct uses of the hot brine cover dozens of industries and processes. An example of multiple uses in the USSR is shown. A research spin-off: a sensitive in-line benzene monitor has been designed by USL and will be tested in the near future. An in-line pH monitor is also under development for the harsh conditions of the geopressured-geothermal wells. 24 refs., 12 figs.

DOE Green Energy (OSTI)

Continuous microseismic monitoring networks have been established around three US Department of Energy geopressured-geothermal design wells in southwestern Louisiana since summer 1980 to assess the effects well development may have on subsidence and growth fault activation. The results obtained from this monitoring have shown several unusual characteristics associated with Gulf Coast seismic activity. The observed activity is classified into two dominant types, one with identifiable body phases and the other with only surface wave signatures. The latter type comprises over 99% of the reported 1000+ microseismic event locations. The problem with the slow-moving surface-wave signature events is that rainfall and weather-associated frontal passages seem closely related to these periods of seismic activity at all three wells. After relatively short periods and low levels of flow testing at the Parcperdue and Sweet Lake prospects, seismic monitoring has shown little credible correlation to inferred growth fault locations during periods of flow testing. Longer periods and higher volumes of flow testing at the Rockefeller Refuge prospect should provide a truer indication of induced seismicity attributable to geopressured-geothermal development. 4 refs., 5 figs.

Final report on decommissioning boreholes and wellsite restoration, Gulf Coast Interior Salt Domes of Mississippi  

Science Conference Proceedings (OSTI)

In 1978, eight salt domes in Texas, Louisiana, and Mississippi were identified for study as potential locations for a nuclear waste repository as part of the National Waste Terminal Storage (NWTS) program. Three domes were selected in Mississippi for ``area characterization`` phase study as follows: Lampton Dome near Columbia, Cypress Creek Dome near New Augusta, and Richton Dome near Richton. The purpose of the studies was to acquire geologic and geohydrologic information from shallow and deep drilling investigations to enable selection of sites suitable for more intensive study. Eleven deep well sites were selected for multiple-well installations to acquire information on the lithologic and hydraulic properties of regional aquifers. In 1986, the Gulf Coast salt domes were eliminated from further consideration for repository development by the selection of three candidate sites in other regions of the country. In 1987, well plugging and restoration of these deferred sites became a closeout activity. The primary objectives of this activity are to plug and abandon all wells and boreholes in accordance with state regulations, restore all drilling sites to as near original condition as feasible, and convey to landowners any wells on their property that they choose to maintain. This report describes the activities undertaken to accomplish these objectives, as outlines in Activity Plan 1--2, ``Activity Plan for Well Plugging and Site Restoration of Test Hole Sites in Mississippi.``

Marine mammal fauna of potential OTEC sites in the Gulf of Mexico and Hawaii  

DOE Green Energy (OSTI)

Twenty-seven marine mammal species have been recorded for the Gulf of Mexico, including 7 Mysticetes or baleen whales, 17 Odontocetes or toothed whales, 1 Sirenian (manatee), and 1 or 2 Pinnipeds or seals. The most common species in the Gulf is the bottlenosed dolphin, an inshore species. Offshore, the spotted dolphin, is fairly common. Most other species are recorded from very few sightings or strandings. None of the endangered species is common in potential OTEC sites in the Gulf of Mexico. Twenty-two marine mammals may occur in Hawaii; 2 Mystecetes, 19 Odonotocetes, and the endemic monk seal. The monk seal, an endangered species, lives in the extreme northwestern island chain away from potential OTEC sites. Among the most common cetaceans in Hawaii is the endangered humpback whale. The spinner dolphin and the bottlenosed dolphin are also fairly common. The baleen whales feed on zooplankton during the summer in polar waters, and are migratory, while the toothed whales feed mainly on fish and squid, and are found in temperate or tropical regions year-round. The manatee is vegetarian and the pinnipeds are fish- or squid-eaters. Environmental effects of OTEC which may affect mammals are: toxic effects of biocide release or ammonia spill, biostimulating effects of seawater redistribution, oil spills, or effects of the physical presence of OTEC plants.

Extreme wave height estimation for ocean engineering applications in the Gulf of Mexico  

E-Print Network (OSTI)

Recent hurricanes in the Gulf of Mexico (e.g., Ivan, Dennis, Katrina, Rita and Ike) were observed to develop wave conditions that were near or exceeded the predicted 100-year conditions. As a result, many offshore facilities, as well as coastal infrastructure, which were designed to withstand the 100-year condition, were damaged. New estimates of extreme conditions, which incorporate recently observed maxima, are needed to provide better guidelines for design of coastal and offshore structures. Berek et al. (2007) have used modeled data to develop new criteria, but these estimates can be very sensitive to the data and to the statistical methods used in the development. Berek's estimates also do not cover the entire Gulf of Mexico. We have developed updated estimates of the 100-year extreme wave conditions for the entire Gulf of Mexico using a more comprehensive approach. First, the applicability of standard parametric wind models was examined and appropriate adjustments to the Rankine vortex model were developed to reduce the wind field errors during hurricane conditions. The adjusted winds reduced the error by up to 25 percent compared to the original Rankine vortex model. To obtain reliable wave data, merged wind fields were generated using the NCEP/NCAR Reanalysis 1 project modeled wind data for background wind and the parametric wind model for hurricane conditions. Next, the SWAN wave model was used for the 51-year period from 1958 to 2008 along with multiple statistical methods (Gumbel, Weibull and GEV-Generalized Extreme Value distribution). The effect of the recent hurricane season (2004-2008) shows that maximum 100-year wave height values and their distribution changes. A resampling technique (bootstrap) is used to evaluate and select the optimum statistical method to estimate more appropriate extreme wave conditions.

Site Selection for DOE/JIP Gas Hydrate Drilling in the Northern Gulf of Mexico  

Science Conference Proceedings (OSTI)

In the late spring of 2008, the Chevron-led Gulf of Mexico Gas Hydrate Joint Industry Project (JIP) expects to conduct an exploratory drilling and logging campaign to better understand gas hydrate-bearing sands in the deepwater Gulf of Mexico. The JIP Site Selection team selected three areas to test alternative geological models and geophysical interpretations supporting the existence of potential high gas hydrate saturations in reservoir-quality sands. The three sites are near existing drill holes which provide geological and geophysical constraints in Alaminos Canyon (AC) lease block 818, Green Canyon (GC) 955, and Walker Ridge (WR) 313. At the AC818 site, gas hydrate is interpreted to occur within the Oligocene Frio volcaniclastic sand at the crest of a fold that is shallow enough to be in the hydrate stability zone. Drilling at GC955 will sample a faulted, buried Pleistocene channel-levee system in an area characterized by seafloor fluid expulsion features, structural closure associated with uplifted salt, and abundant seismic evidence for upward migration of fluids and gas into the sand-rich parts of the sedimentary section. Drilling at WR313 targets ponded sheet sands and associated channel/levee deposits within a minibasin, making this a non-structural play. The potential for gas hydrate occurrence at WR313 is supported by shingled phase reversals consistent with the transition from gas-charged sand to overlying gas-hydrate saturated sand. Drilling locations have been selected at each site to 1) test geological methods and models used to infer the occurrence of gas hydrate in sand reservoirs in different settings in the northern Gulf of Mexico; 2) calibrate geophysical models used to detect gas hydrate sands, map reservoir thicknesses, and estimate the degree of gas hydrate saturation; and 3) delineate potential locations for subsequent JIP drilling and coring operations that will collect samples for comprehensive physical property, geochemical and other analyses.

Analysis of the potential use of geothermal energy for power generation along the Texas Gulf Coast  

DOE Green Energy (OSTI)

Three forms of potential geothermal energy may exist in the State of Texas: hot rocks in the Trans Pecos region, convection type geothermal water in the Rio Grande Rift basin, and geopressured geothermal water along the Gulf Coast. Of these, only the geopressured waters have been verified. Exploration wells for oil and gas have established the presence of deep hot water deposits along the coastal area, offshore and inland for 75 miles. These exist in thick shale and sand beds in the geopressured zone. The most favorable area appears to be at depths of 12,000 to 15,000 feet where the temperatures range from 300 to 400/sup 0/F. Indications are that a series of relatively small, 10 to 50 megawatt, power plants could be located along the coastal plain of Texas. These plants could produce at least 20,000 megawatts and possibly as much as 100,000 megawatts under the most favorable conditions. Cost of the power appears to be in the range of 25 to 35 mills per kilowatt hour in 1980 providing the water is saturated with natural gas which could be sold to offset some of the cost. If the gas is present, at least 6 billion cubic feet per day of natural gas would be produced. Unit capital investment for such plants would exceed projected costs for nuclear or fossil fueled power plants. Successful development of a demonstration plant with public funds could establish the viability of geopressured waters as a source of power and natural gas and encourage private investment to exploit this energy source, should it prove competitive with other sources of electric power generation.

Potential Economic Impacts from Offshore Wind in the Gulf of Mexico Region (Fact Sheet)  

SciTech Connect

Offshore wind is a clean, renewable source of energy and can be an economic driver in the United States. To better understand the employment opportunities and other potential regional economic impacts from offshore wind development, the U.S. Department of Energy (DOE) funded research that focuses on four regions of the country. The studies use multiple scenarios with various local job and domestic manufacturing content assumptions. Each regional study uses the new offshore wind Jobs and Economic Development Impacts (JEDI) model, developed by the National Renewable Energy Laboratory. This fact sheet summarizes the potential economic impacts for the Gulf of Mexico region.

Zooplankton from OTEC sites in the Gulf of Mexico and the Caribbean  

DOE Green Energy (OSTI)

The spatial and temporal variations in the abundance of major classes of zooplankton were measured using standard methods, between June and October 1978, at two OTEC sites in the Gulf of Mexico and in the Caribbean near Puerto Rico. The usual oceanic patterns were found with highest numbers near the surface, especially at night, and lowest numbers at 800 to 1000 m. Absolute numbers varied considerably from site to site. As expected, copepods (usually divided between calanoids and cyclopoids) dominated the zooplankton at all sites.

In 1985, the Minerals Management Service initiated an investigation to study the causes of wetland loss in the coastal Gulf of Mexico as part of its Outer Continental Shelf environmental-studies program. The purpose of the two-year study was to investigate the factors that contribute to wetland loss and to determine specifically what percentage of the loss is directly and indirectly related to Federal offshore oil and gas development. The primary goal of the Coastal Effects Program is to delineate the onshore impacts of offshore oil and gas development activities. Volume 3 contains five appendices providing methodological details and data listings.

Preliminary assessment of high-resistivity cap-rock shale in the Frio Formation of the Texas Gulf Coast. Annual report  

DOE Green Energy (OSTI)

Mapping of high resistivity cap rock shales in the Frio Formation of the Texas Gulf Coast shows that few areas of thin cap rock occur in the upper Texas Gulf Coast, and more extensive, thicker cap rock occurs in the lower Texas Gulf Coast. Increases in (1) maximum shale resistivity, (2) unstable minerals (volcanic rock fragments, detrital carbonate grains), and (3) authigenic cementation parallel the increase in cap rock from the upper to the lower Gulf Coast. Similarity in cap rock distribution in two major Frio deltaic depocenters is not evident. Facies analysis of regional cross sections in the lower Texas Gulf Coast and of cross sections in Sarita East field, Kenedy County, shows preferential development of cap rock in the delta-front/slope facies of the Norias delta system. Sand content of the cap rock interval varies from 23 to 41 percent in part of Sarita East field, suggesting that if cap rock is due to authigenic cementation, such sands may act as fluid conduits during mineralization. Cap rock is rarely developed in the shale-rich prodelta and distal delta-front facies. High resistivity cap rock shales have been considered a result of authigenic calcite cementation, but definite evidence for this origin is lacking. Preliminary mineralogic analyses of well cuttings have not yielded satisfactory results. Analysis of core through cap rock and non-cap rock intervals will be required to determine the mineralogic variability within each interval and to accurately assess any mineralogic control of the high resistivity log response.

Population dynamics and movements of the Kemp's ridley sea turtle, lepidochelys kempii, in the northwestern Gulf of Mexico  

E-Print Network (OSTI)

The Kemp’s ridley sea turtle, Lepidochelys kempii, is recovering from devastating declines that reduced nesting activity from a single-day estimate of 10,000- 40,000 females in 1947 to fewer than 300 during all of 1985. Nesting beach monitoring is crucial to estimating population size and reproductive activity, but in-water data are essential for understanding population dynamics and evaluating management strategies. Hook-and-line, stranding, and nesting records, satellite telemetry, and diet analyses were used to characterize ridley population dynamics and movements in the northwestern Gulf of Mexico during 2003-2007. Recreational hook-and-line captures comprised approximately one third of non-nesting encounters along Galveston and Jefferson Counties, Texas. The hook-and-line dataset displayed similar geographical and monthly trends to that of strandings, but was devoid of pelagic-stage, subadult, and adult ridleys. Coastal and bay waters along the upper Texas and western Louisiana coasts were utilized by immature ridleys during warmer months. Nesting occurred along Galveston Island on both armored and unarmored beaches. Inter-nesting females exhibited fidelity to Galveston during nesting season and subsequently migrated to federal waters offshore Louisiana. Crabs were important components of benthic-stage (>25 cm SCL) ridley diet, while worm tubes were targeted by some individuals. Short satellite track durations for immature ridleys precipitated examinations of biofouling, attachment protocols, and turtle excluder device (TED) interactions. Antifouling paints drastically reduced fouling of transmitters. A less-rigid neoprene attachment method was developed to increase transmitter retention on fast-growing juveniles, but further trials are necessary. Transmitters were not damaged or lost during TED trials, but turtle escape times increased when transmitters wedged between TED bars. Projected population growth will increase numbers of Kemp’s ridleys utilizing the Gulf of Mexico and interacting with human activities. Future research should examine year-round distribution and abundance of all life history stages and further characterize recreational hook-and-line capture, nesting activity, movements, and diet. Education efforts targeting the beach-going public, beach residents and workers, and the recreational fishing sector should be employed to promote sea turtle reporting and minimize negative interactions. State and federal managers should examine anthropogenic impacts within the region and determine the need for mitigation and/or regulations to promote continued species recovery.

Significant test results, energy potential, and geology of some Gulf Coast geopressured-geothermal sandstone reservoirs  

Science Conference Proceedings (OSTI)

Geopressured-geothermal reservoir found in the northern Gulf of Mexico basin represent a large potential future energy resource. Three reservoirs in various stages of developmental testing are of current interest. Over a four-year testing period the Gladys McCall 1 (Cameron Parish, Louisiana) produced 27.3 million bbl of brine and 676 million scf of gas at an average rate of 20,000 bbl/day from perforations between 15,158 and 15,490 ft. This lower Miocene sandstone section forms part of a genetic unit of interconnected channel and point-bar sandstones deposited in a lower shelf environment. Pleasant Bayou 2 well (Brazoria County, Texas) is currently being flow-tested at 20,000 bbl/day and has a gas/brine ratio of approximately 23 scf/stb and a temperature of 291/degrees/F. An electric energy conversion system being set up here will test potential for electric generation from geopressured-geothermal energy. Superior Hulin 1 (Vermilion Parish, Louisiana) is a deep (21,549 ft) former gas well proposed to be completed as a geopressured-geothermal well. Initial log analysis indicates that a 570-ft thick sandstone, of probable submarine fan origin, may contain free gas in addition to solution gas and may thus represent an economically feasible geopressured-geothermal well. Gas-separated brine is disposed by subsurface injection into disposal wells. However, in areas where hydrocarbon fields with wells penetrating geopressured sands are present, hot brines could be injected into depleted hydrocarbon zones to aid secondary recovery.

Properties of Geopressured Brines and Wells in the Gulf Coast and Opportunities for Industrial/Research Participation  

DOE Green Energy (OSTI)

Geopressured reservoirs exhibit pressure gradients in excess of the normal hydrostatic gradient. In the Gulf Coast area the normal gradient is 0.465 psi/ft. Pressures may approach lithostatic pressure and have been measured as high as 1.05 psi/ft in the Gulf Coast area. Geopressured basins exist worldwide and in a number of U.S. locations, east, west, north and south. The Gulf Coast area has been studied extensively and is the subject of the DOE geopressured-geothermal research at present. The assumed ranges in resource characteristics include: depth from -12,000 to > -20,000 feet, brine flow rate from 20,000 to 40,000 bpd, temperature from 300 to 400 F, bottomhole pressure from 12,000 to 18,500 psi; salinity from 20,000 to 200,000 mg/L, gas-water ratio from 40 to 80 scf/bbl., and condensate from a trace to production. Energy in the geopressured resource includes gas, thermal, and hydraulic energy. It has been estimated that there are 6,000 quads of methane and 11,000 quads of thermal energy in the Gulf Coast area geopressured-geothermal reservoirs. Estimates run as high as 50,000 quad for the thermal energy (Wallace et al, 1978). Present industrial interest in the Pleasant Bayou and Hulin wells includes: desalination plants, an economic study by a power company for regional use, use of generated electricity by a coalition of towns, aquaculture (catfish farming) research program, and an unsolicited proposal for enhanced oil recovery of heavy oil. Direct uses of the hot brine cover dozens of industries and processes. An example of multiple uses in the USSR is shown. Outside agency interest includes the U.S.G.S., N.S.F., G.R.I., and possibly other areas within DOE. A research spin-off: a sensitive in-line benzene monitor has been designed by USL and will be tested in the near future. An in-line pH monitor is also under development for the harsh conditions of the geopressured-geothermal wells.

Support of Gulf of Mexico Hydrate Research Consortium: Activities to Support Establishment of a Sea Floor Monitoring Station Project  

SciTech Connect

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health, was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical, geological, and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 (MC118) in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. These delays caused scheduling and deployments difficulties but many sensors and instruments were completed during this period. Software has been written that will accommodate the data that the station retrieves, when it begins to be delivered. In addition, new seismic data processing software has been written to treat the peculiar data to be received by the vertical line array (VLA) and additional software has been developed that will address the horizontal line array (HLA) data. These packages have been tested on data from the test deployments of the VLA and on data from other, similar, areas of the Gulf (in the case of the HLA software). The CMRET has conducted one very significant research cruise during this reporting period: a March cruise to perform sea trials of the Station Service Device (SSD), the custom Remotely Operated Vehicle (ROV) built to perform several of the unique functions required for the observatory to become fully operational. March's efforts included test deployments of the SSD and Florida Southern University's mass spectrometer designed to measure hydrocarbon gases in the water column and The University of Georgia's microbial collector. The University of Georgia's rotational sea-floor camera was retrieved as was Specialty Devices storm monitor array. The former was deployed in September and the latter in June, 2006. Both were retrieved by acoustic release from a dispensable weight. Cruise participants also went prepared to recover any and all instruments left on the sea-floor during the September Johnson SeaLink submersible cruise. One of the pore-fluid samplers, a small ''peeper'' was retrieved successfully and in fine condition. Other instrumentation was left on the sea-floor until modifications of the SSD are complete and a return cruise is accomplished.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT

Development of the station has always included the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. This possibility has recently achieved reality via the National Institute for Undersea Science and Technology's (NIUST) solicitation for proposals for research to be conducted at the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research.

Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, have had to be postponed and the use of the vessel M/V Ocean Quest and its two manned submersibles sacrificed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort is being made to locate and retain the services of a replacement vessel and submersibles or Remotely Operated Vehicles (ROVs) but these efforts have been fruitless due to the demand for these resources in the tremendous recovery effort being made in the Gulf area. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA). Subcontractors with FY03 funding fulfilled their technical reporting requirements in the previous report (41628R10). Only unresolved matching funds issues remain and will be addressed in the report of the University of Mississippi's Office of Research and Sponsored Programs.

Deepwater Gulf of Mexico turbidites -- Compaction effects on porosity and permeability  

SciTech Connect

The deepwater Gulf of Mexico is now a major area of activity for the US oil industry. Compaction causes particular concern because most prospective deepwater reservoirs are highly geo-pressured and many have limited aquifer support; water injection may also be problematic. To address some of the issues associated with compaction, the authors initiated a special core-analysis program to study compaction effects on turbidite sand porosity and permeability specifically. This program also addressed a number of subsidiary but no less important issues, such as sample characterization and quality, sample preparation, and test procedures. These issues are particularly pertinent, because Gulf of Mexico turbidites are generally unconsolidated, loose sands, and are thus susceptible to a whole array of potentially serious core-disturbing processes. One key result of the special core analysis program is that turbidite compressibilities exhibit large variations in both magnitude and stress dependence. These variations correlate with creep response in the laboratory measurements. The effects of compaction on permeability are significant. To eliminate complicating effects caused by fines movement, the authors made oil flow measurements at initial water saturation. The measurements indicate compaction reduces permeability four to five times more than porosity on a relative basis.

Spatial and temporal distributions of particulate matter and particulate organic carbon, Northeast Gulf of Mexico  

E-Print Network (OSTI)

The distribution of particulate matter (PM) and particulate organic carbon (POC) was determined during the Northeast Gulf of Mexico Chemical Oceanography and Hydro-graphy program (NEGOM). The hydrography and physical forcing functions were examined to explain particulate matter distribution. PM and POC were determined for discrete samples, and PM was also compared with in situ beam attenuation measure-ments in order to make estimations of continuous particle concentration profiles. Measurements were made three times per year for three years, during 1997-1998, 1998-1999, and 1999-2000, but only the first two years' worth of results are reported here. PM distributions vary seasonally and interannually. General patterns tend to be fairly consistent spatially and temporally during fall and spring, but intensity changes accord-ing to season. Differences present at the surface appear to be due mainly to riverine input of nutrients and particles from the several major rivers that flow into the northeastern Gulf of Mexico. Wind-forced circulation appears to be a minor influence on surface particulate distribution. Secondary eddies can have an effect upon distribution, as seen with an anticyclonic feature over the upper slope during Summer 1998 which entrained less saline, high particulate river water offshore. A similar effect was noted during Summer 1999, but to a lesser degree. A shelf edge current associated with anticyclonic flow seems to be a mechanism responsible for the appearance of nepheloid layers on the outer shelf.

Improved recovery from Gulf of Mexico reservoirs. Quarterly status report, January 1--March 31, 1996  

Science Conference Proceedings (OSTI)

On February 18, 1992, Louisiana State University with two technical subcontractors, BDM, Inc. and ICF, Inc., began a research program to estimate the potential oil and gas reserve additions that could result from the application of advanced secondary and enhanced oil recovery technologies and the exploitation of undeveloped and attic oil zones in the Gulf of Mexico oil fields that are related to piercement salt domes. This project is a one year continuation of this research and will continue work in reservoir description, extraction processes, and technology transfer. Detailed data will be collected for two previously studies reservoirs: a South Marsh Island reservoir operated by Taylor Energy and one additional Gulf of Mexico reservoir operated by Mobil. Additional reservoirs identified during the project will also be studied if possible. Data collected will include reprocessed 2-D seismic data, newly acquired 3-D data, fluid data, fluid samples, pressure data, well test data, well logs, and core data/samples. The new data will be used to refine reservoir and geologic characterization of these reservoirs. Further laboratory investigation will provide additional simulation input data in the form of PVT properties, relative permeabilities, capillary pressure, and water compatibility. Geological investigations will be conducted to refine the models of mud-rich submarine fan architectures used by seismic analysts and reservoir engineers. Research on advanced reservoir simulation will also be conducted. This report describes a review of fine-grained submarine fans and turbidite systems.

Geothermal resources of the Texas Gulf Coast: environmental concerns arising from the production and disposal of geothermal waters. Geological circular 76-7  

DOE Green Energy (OSTI)

Disposal and temporary surface storage of spent geothermal fluids and surface subsidence and faulting are the major environmental problems that could arise from geopressured geothermal water production. Geopressured geothermal fluids are moderately to highly saline and may contain significant amounts of boron. Disposal of hot saline geothermal water in subsurface saline aquifers will present the least hazard to the environment. It is not known, however, whether the disposal of as much as 54,000 m/sup 3/ of spent fluids per day into saline aquifers at the production site is technically or economically feasible. If saline aquifers adequate for fluid disposal cannot be found, geothermal fluids may have to be disposed of by open watercourses, canals, and pipelines to coastal bays on the Gulf of Mexico. Overland flow or temporary storage of geothermal fluids may cause negative environmental impacts. As the result of production of large volumes of geothermal fluid, reservoir pressure declines may cause compaction of sediments within and adjacent to the reservoir. The amount of compaction depends on pressure decline, reservoir thickness, and reservoir compressibility. The magnitude of environmental impact of subsidence and fault activation varies with current land use. Geothermal resource production facilities on the Gulf Coast of Texas could be subject to a series of natural hazards: (1) hurricane- or storm-induced flooding, (2) winds from tropical storms, (3) coastal erosion, or (4) expansive soils. None of these hazards is generated by geothermal resource production, but each has potential for damaging geothermal production and disposal facilities that could, in turn, result in leakage of hot saline geothermal fluids.

Volume and accessibility of entrained (solution) methane in deep geopressured reservoirs - tertiary formations of the Texas Gulf Coast. Final report  

DOE Green Energy (OSTI)

The objective of this project was to appraise the total volume of in-place methane dissolved in formation waters of deep sandstone reservoirs of the onshore Texas Gulf Coast within the stratigraphic section extending from the base of significant hydrocarbon production (8000 ft)* to the deepest significant sandstone occurrence. The area of investigation is about 50,000 mi/sup 2/. Factors that determine the total methane resource are reservoir bulk volume, porosity, and methane solubility; the latter is controlled by the temperature, pressure, and salinity of formation waters. Regional assessment of the volume and the distribution of potential sandstone reservoirs was made from a data base of 880 electrical well logs, from which a grid of 24 dip cross sections and 4 strike cross sections was constructed. Solution methane content in each of nine formations or divisions of formations was determined for each subdivision. The distribution of solution methane in the Gulf Coast was described on the basis of five reservoir models. Each model was characterized by depositional environment, reservoir continuity, porosity, permeability, and methane solubility.

GULF OF MEXICO SEAFLOOR STABILITY AND GAS HYDRATE MONITORING STATION PROJECT  

SciTech Connect

The gas hydrates research Consortium (HRC), established and administered at the University if Mississippi's Center for Marine Research and Environmental Technology (CMRET) has been active on many fronts in FY 03. Extension of the original contract through March 2004, has allowed completion of many projects that were incomplete at the end of the original project period due, primarily, to severe weather and difficulties in rescheduling test cruises. The primary objective of the Consortium, to design and emplace a remote sea floor station for the monitoring of gas hydrates in the Gulf of Mexico by the year 2005 remains intact. However, the possibility of levering HRC research off of the Joint Industries Program (JIP) became a possibility that has demanded reevaluation of some of the fundamental assumptions of the station format. These provisions are discussed in Appendix A. Landmark achievements of FY03 include: (1) Continuation of Consortium development with new researchers and additional areas of research contribution being incorporated into the project. During this period, NOAA's National Undersea Research Program's (NURP) National Institute for Undersea Science and Technology (NIUST) became a Consortium funding partner, joining DOE and Minerals Management Service (MMS); (2) Very successful annual and semiannual meetings in Oxford Mississippi in February and September, 2003; (3) Collection of piston cores from MC798 in support of the effort to evaluate the site for possible monitoring station installation; (4) Completion of the site evaluation effort including reports of all localities in the northern Gulf of Mexico where hydrates have been documented or are strongly suspected to exist on the sea floor or in the shallow subsurface; (5) Collection and preliminary evaluation of vent gases and core samples of hydrate from sites in Green Canyon and Mississippi Canyon, northern Gulf of Mexico; (6) Monitoring of gas activity on the sea floor, acoustically and thermally; (7) Design, construction, and successful deployment of an in situ pore-water sampling device; (8) Improvements to the original Raman spectrometer (methane sensor); (9) Laboratory demonstration of the impact of bacterially-produced surfactants' rates of hydrate formation; (10) Construction and sea floor emplacement and testing--with both watergun and ship noise sources--of the prototypal vertical line array (VLA); (11) Initiation of studies of spatial controls on hydrates; (12) Compilation and analyses of seismic data, including mapping of surface anomalies; (13) Additional field verification (bottom samples recovered), in support of the site selection effort; (14) Collection and preliminary analyses of gas hydrates from new sites that exhibit variant structures; (15) Initial shear wave tests carried out in shallow water; (16) Isolation of microbes for potential medicinal products development; (17) Preliminary modeling of occurrences of gas hydrates.

Scientific Objectives of the Gulf of Mexico Gas Hydrate JIP Leg II Drilling  

Science Conference Proceedings (OSTI)

The Gulf of Mexico Methane Hydrate Joint Industry Project (JIP) has been performing research on marine gas hydrates since 2001 and is sponsored by both the JIP members and the U.S. Department of Energy. In 2005, the JIP drilled the Atwater Valley and Keathley Canyon exploration blocks in the Gulf of Mexico to acquire downhole logs and recover cores in silt- and clay-dominated sediments interpreted to contain gas hydrate based on analysis of existing 3-D seismic data prior to drilling. The new 2007-2009 phase of logging and coring, which is described in this paper, will concentrate on gas hydrate-bearing sands in the Alaminos Canyon, Green Canyon, and Walker Ridge protraction areas. Locations were selected to target higher permeability, coarser-grained lithologies (e.g., sands) that have the potential for hosting high saturations of gas hydrate and to assist the U.S. Minerals Management Service with its assessment of gas hydrate resources in the Gulf of Mexico. This paper discusses the scientific objectives for drilling during the upcoming campaign and presents the results from analyzing existing seismic and well log data as part of the site selection process. Alaminos Canyon 818 has the most complete data set of the selected blocks, with both seismic data and comprehensive downhole log data consistent with the occurrence of gas hydrate-bearing sands. Preliminary analyses suggest that the Frio sandstone just above the base of the gas hydrate stability zone may have up to 80% of the available sediment pore space occupied by gas hydrate. The proposed sites in the Green Canyon and Walker Ridge areas are also interpreted to have gas hydrate-bearing sands near the base of the gas hydrate stability zone, but the choice of specific drill sites is not yet complete. The Green Canyon site coincides with a 4-way closure within a Pleistocene sand unit in an area of strong gas flux just south of the Sigsbee Escarpment. The Walker Ridge site is characterized by a sand-prone sedimentary section that rises stratigraphically across the base of the gas hydrate stability zone and that has seismic indicators of gas hydrate.

Support of Gulf of Mexico Hydrate Research Consortium: Activities to Support Establishment of a Sea Floor Monitoring Station Project  

SciTech Connect

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health, was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical, geological, and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The CMRET has conducted several research cruises during this reporting period: one in April, one in June, one in September. April's effort was dedicated to surveying the mound at MC118 with the Surface-Source-Deep-Receiver (SSDR) seismic surveying system. This survey was completed in June and water column and bottom samples were collected via box coring. A microbial filtering system developed by Consortium participants at the University of Georgia was also deployed, run for {approx}12 hours and retrieved. The September cruise, designed to deploy, test, and in some cases recover, geochemical and microbial instruments and experiments took place aboard Harbor Branch's Seward Johnson and employed the Johnson SeaLink manned submersible. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA). Subcontractors with FY03 funding fulfilled their technical reporting requirements in a previously submitted report (41628R10). Only unresolved matching funds issues remain and will be addressed in the report of the University of Mississippi's Office of Research and Sponsored Programs. In addition, Barrodale Computing Services Ltd. (BCS) completed their work; their final report is the bulk of the semiannual report that precedes (abstract truncated)

Causes of wetland loss in the coastal Gulf of Mexico, Volume 1: executive summary. Final report  

SciTech Connect

In 1985, the Minerals Management Service initiated an investigation to study the causes of wetland loss in the coastal Gulf of Mexico as part of its Outer Continental Shelf environmental-studies program. The purpose of the two-year study was to investigate the factors that contribute to wetland loss and to determine specifically what percentage of the loss is directly and indirectly related to Federal offshore oil and gas development. The primary goal of the Coastal Effects Program is to delineate the onshore impacts of offshore oil and gas development activities. The final report, prepared in three volumes, describes the extent of the contribution of OCS development to coastal land loss. Volume I is the Executive Summary. The report provides a detailed description of both direct and indirect impacts.

Architectural characteristics of fine-grained submarine fans: A model applicable to the Gulf of Mexico  

Science Conference Proceedings (OSTI)

Submarine fan deposits in the Gulf of Mexico, modern and ancient, fall in the category of fine-grained, low overall sand/shale ratio basin-floor fans. Models published over the years that have been applied to both exploration and production are based on sand-rich fans, most of which were deposited in active margin settings. These models should not be used for the Gulf of Mexico or any other deep water system with similar basinal settings. Observations from the excellent outcrops of the Permian Tanqua Karoo in southwestern South Africa, together with information from the modern Mississippi Fan, and the Jackfork turbidites in Arkansas, enable the construction of a model that addresses the architecture of both the macro and meso-scale depositional features of fine-grained turbidite systems. At the entrance to the basin floor the conduit, carved out across the slope, may start to widen. Most of the density flows moving through do not necessarily occupy the conduit`s entire width. The result is a complex of laterally and vertically stacked channel fills and associated levee-overbank deposits with a good degree of connectivity. The channel fills are mostly massive, whereas the levee deposits are low-contrast, low-resistivity thin-bedded sandstones and shales with high permeability. Such sandstones can be potentially very productive. The channels gradually become smaller and as their influence on directing the heads of turbidity currents decreases, oblong sheet sands are deposited, each having a very large width to thickness ratio and a high sand/shale ratio. The vertical stacking patterns within these sheet sands commonly display lateral offset of individual beds or groups of beds, and therefore form a distinct reservoir type with varying internal fluid-flow characteristics.

Support of Gulf of Mexico Hydrate Research Consortium: Activities of Support Establishment of a Sea Floor Monitoring Station Project  

SciTech Connect

The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research that shared the need for a way to conduct investigations of gas hydrates and their stability zone in the Gulf of Mexico in situ on a more-or-less continuous basis. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (SFO) on the sea floor in the northern Gulf of Mexico, in an area where gas hydrates are known to be present at, or just below, the sea floor and to discover the configuration and composition of the subsurface pathways or 'plumbing' through which fluids migrate into and out of the hydrate stability zone (HSZ) to the sediment-water interface. Monitoring changes in this zone and linking them to coincident and perhaps consequent events at the seafloor and within the water column is the eventual goal of the Consortium. This mission includes investigations of the physical, chemical and biological components of the gas hydrate stability zone - the sea-floor/sediment-water interface, the near-sea-floor water column, and the shallow subsurface sediments. The eventual goal is to monitor changes in the hydrate stability zone over time. Establishment of the Consortium succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among those involved in gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative methods and construct necessary instrumentation. Following extensive investigation into candidate sites, Mississippi Canyon 118 (MC118) was chosen by consensus of the Consortium at their fall, 2004, meeting as the site most likely to satisfy all criteria established by the group. Much of the preliminary work preceding the establishment of the site - sensor development and testing, geophysical surveys, and laboratory studies - has been reported in agency documents including the Final Technical Report to DOE covering Cooperative Agreement DEFC26-00NT40920 and Semiannual Progress Reports for this award, DE-FC26-02NT41628. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in MC118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. SFO completion, now anticipated for 2009-10, has, therefore, been delayed. Although delays caused scheduling and deployment difficulties, many sensors and instruments were completed during this period. Software has been written that will accommodate the data that the station retrieves, when it begins to be delivered. In addition, new seismic data processing software has been written to treat the peculiar data to be received by the vertical line array (VLA) and additional software has been developed that will address the horizontal line array (HLA) data. These packages have been tested on data from the test deployments of the VLA and on data from other, similar, areas of the Gulf (in the case of the HLA software). During the life of this Cooperative Agreement (CA), the CMRET conducted many cruises. Early in the program these were executed primarily to survey potential sites and test sensors and equipment being developed for the SFO. When MC118 was established as the observatory site, subsequent cruises focused on this location. Beginning in 2005 and continuing to the present, 13 research cruises to MC118 have been conducted by the Consortium. During September, 2006, the Consortium was able to secure 8 days aboard the R/V Seward Johnson with submersible Johnson SeaLink, a critical chapter in the life of the Observatory project as important documentation, tests, recoveries and deployments were accomplished during this trip (log appended). Consortium members have participated materially in a number of additional cruises including several of the NIUST autonomous underwater vehicle (AUV), Ea

Economic Effects of Land Subsidence Due to Excessive Groundwater Withdrawal in the Texas Gulf Coast Area  

E-Print Network (OSTI)

Land surface subsidence continues to be a destructive force in the Texas Gulf Coast area. The sinking of the surface has been linked by engineers to the withdrawal of groundwater. Subsidence causes damages and property value losses as saltwater encroachment is increased, property is permanently inundated, and temporary flooding is intensified. This study provides estimates of private and public costs attributable to land subsidence in a 945 square mile area that has subsided one foot or more since 1943. Estimates are divided into three sub-areas within this total area to provide insight into the incidence of subsidence-related costs. The sub-areas considered in this study were sub-area I, an 83 square mile area between Houston and Baytown containing square mile sample blocks adjacent to the upper Galveston bay and/or Buffalo Bayou and the Houston Ship Channel; sub-area II, the 25 square mile area surrounding Clear Lake and adjacent land fronting on Galveston bay; and sub-area III, the remaining area within the total 945 square mile area that had experienced subsidence of approximately two feet or more since 1943. Personal interviews, using questionnaires designed for reporting of damages and property value losses by a random sample of owners of residential, commercial and industrial property, comprised the data base for estimating total private costs attributable to subsidence. Public costs (federal, state, county and municipal) were obtained from personal interviews with public officials. In total, over 1100 interviews were conducted in the study area. Data from these interviews were expanded to total cost estimates for the subsiding area. Physical effects of surface subsidence were found to be largely dependent upon location of the property. Most damages and losses in property value occur in those areas in close proximity to Galveston bay and/or major waterways. Temporary flooding, permanent inundation, bulkheading and landfilling were the major subsidence-related causes of cost and/or losses in property value. Structural damages, largely from subsidence aggravated surface faults, were also significant. These comprised a higher proportion of damages in areas remote from the waterfront than in low lying areas subject to frequent flooding or permanent inundation. Estimated annual costs and property value losses totaled over $31.7 million per year for the study area as a whole. These were primarily costs to residential, commercial and industrial property owners, but included over $.5 million per year in public costs for damage abatement or repair to public facilities. Estimated costs by sub-areas revealed a higher incidence and intensity of damage and property value loss in waterfront (I and II) than in non-waterfront areas (III). Estimated costs in sub-areas I, II and III were $8.79 million, $5 million and $17.4 million, respectively. Sub-area I, which made up about 8.8 percent of the total study area, experienced 27.7 percent of total subsidence-related costs. Sub-area II experienced 15.8 percent of total costs while occupying only 3 percent of the total study area. And, although sub-area III had almost 55 percent of the total costs, it includes over 88 percent of the total area. Hence, subsidence damages and losses in property value are concentrated heavily in areas in close proximity to the immediate coastline of Galveston bay, Buffalo Bayou, Clear Lake and Taylor Lake. Other sections throughout the study area experienced damages and property losses but less frequently and less intensively. A comparative analysis of the total costs of groundwater pumping with alternative surface water importation was developed to examine the economic feasibility of importing surface water to displace groundwater as a means of avoiding annual subsidence costs. A break-even analysis revealed that for the five year period 1969-73, the importation of surface water to meet all the area's water needs (up to 198.16 billion gallons per year) would have been economically justifi

38-kHz ADCP investigation of deep scattering layers in sperm whale habitat in the northern Gulf of Mexico  

E-Print Network (OSTI)

A hull-mounted 38-kHz phased-array acoustic Doppler current profiler (ADCP) was used to acoustically survey the continental margin of the northern Gulf of Mexico (GOM) during 6 cruises in 2002-2003. This is the first backscatter survey with a 38-kHz ADCP in the Gulf of Mexico. ADCPs have been used as a proxy to measure the volume backscatter return from plankton in the water column, however previous studies were restricted to the upper 200 to 300 meters due to the relatively high frequency of operation (150-300 kHz) of the transducers. In addition to measuring deep water current velocities, the 38-kHz phased-array ADCP can measure Relative Acoustic Backscatter Intensity (RABI) as deep as 1000 meters. The daytime depth of the main deep scattering layer at 400 to 500 meters was resolved, and locally high backscatter intensity can be seen down to 800 meters. The objectives were to determine how to analyze RABI from the instrument to resolve scattering layers, and then to seek secondary deep scattering layers of potential prey species below the main deep scattering layer, from 600 to 800 meters in the feeding range for Gulf of Mexico sperm whales. Based on RABI from the 38-kHz ADCP, secondary DSLs in sperm whale diving range were more commonly recorded over the continental shelf than in the deep basin region of the Gulf of Mexico. The daytime depths of migrating plankton showed variation depending on physical circulation features (cyclone, anticyclone, proximity to Mississippi river, and Loop Current) present. Vertical migrations compared between concurrently running 38 and 153-kHz ADCPs showed an overlap of acoustic scatterers recorded by the two instruments, however the 153-kHz instrument has much finer vertical resolution. Vertical migration rates were calculated and simultaneous net tow samples from one of the cruises was used to compare abundance estimates by the two methods.

Characteristics of produced water discharged to the Gulf of Mexico hypoxiczone.  

Science Conference Proceedings (OSTI)

Each summer, an area of low dissolved oxygen (the hypoxic zone) forms in the shallow nearshore Gulf of Mexico waters from the Mississippi River Delta westward to near the Texas/Louisiana border. Most scientists believe that the leading contributor to the hypoxic zone is input of nutrients (primarily nitrogen and phosphorus compounds) from the Mississippi and Atchafalaya Rivers. The nutrients stimulate growth of phytoplankton. As the phytoplankton subsequently die, they fall to the bottom waters where they are decomposed by microorganisms. The decomposition process consumes oxygen in the bottom waters to create hypoxic conditions. Sources other than the two rivers mentioned above may also contribute significant quantities of oxygen-demanding pollutants. One very visible potential source is the hundreds of offshore oil and gas platforms located within or near the hypoxic zone. Many of these platforms discharge varying volumes of produced water. However, only limited data characterizing oxygen demand and nutrient concentration and loading from offshore produced water discharges have been collected. No comprehensive and coordinated oxygen demand data exist for produced water discharges in the Gulf of Mexico. This report describes the results of a program to sample 50 offshore oil and gas platforms located within the Gulf of Mexico hypoxic zone. The program was conducted in response to a requirement in the U.S. Environmental Protection Agency (EPA) general National Pollutant Discharge Elimination System (NPDES) permit for offshore oil and gas discharges. EPA requested information on the amount of oxygen-demanding substances contained in the produced water discharges. This information is needed as inputs to several water quality models that EPA intends to run to estimate the relative contributions of the produced water discharges to the occurrence of the hypoxic zone. Sixteen platforms were sampled 3 times each at approximately one-month intervals to give an estimate of temporal variability. An additional 34 platforms were sampled one time. The 50 sampled platforms were scattered throughout the hypoxic zone to give an estimate of spatial variability. Each platform was sampled for biochemical oxygen demand (BOD), total organic carbon (TOC), nitrogen (ammonia, nitrate, nitrite, and total Kjeldahl nitrogen [TKN]), and phosphorus (total phosphorus and orthophosphate). In addition to these parameters, each sample was monitored for pH, conductivity, salinity, and temperature. The sampling provided average platform concentrations for each parameter. Table ES-1 shows the mean, median, maximum, and minimum for the sampled parameters. For some of the parameters, the mean is considerably larger than the median, suggesting that one or a few data points are much higher than the rest of the points (outliers). Chapter 4 contains an extensive discussion of outliers and shows how the sample results change if outliers are deleted from consideration. A primary goal of this study is to estimate the mass loading (lb/day) of each of the oxygen-demanding pollutants from the 50 platforms sampled in the study. Loading is calculated by multiplying concentrations by the discharge volume and then by a conversion factor to allow units to match. The loadings calculated in this study of 50 platforms represent a produced water discharge volume of about 176,000 bbl/day. The total amount of produced water generated in the hypoxic zone during the year 2003 was estimated as 508,000 bbl/day. This volume is based on reports by operators to the Minerals Management Service each year. It reflects the volume of produced water that is generated from each lease, not the volume that is discharged from each platform. The mass loadings from offshore oil and gas discharges to the entire hypoxic zone were estimated by multiplying the 50-platform loadings by the ratio of total water generated to 50-platform discharge volume. The loadings estimated for the 50 platforms and for the entire hypoxic zone are shown in Table ES-2. These estimates and the sampling data from 50 platfo

Impacts of Vessel Noise Perturbations on the Resident Sperm Whale Population in the Gulf of Mexico  

E-Print Network (OSTI)

The Gulf of Mexico is home to two of the world?s ten busiest ports by cargo volume, the Port of New Orleans and the Port of Houston; and in 2008, these ports hosted a combined 14,000 ships, a number which is likely only to increase. Past research shows that this increase in shipping worldwide has historically lead to an increase in ambient noise level of 3-5dB per decade. Sperm whales in the Gulf of Mexico are considered a genetically distinct, resident population. They have a preference for the Louisiana-Mississippi Shelf region which directly overlaps with the entrance to the Mississippi and the Port of New Orleans. Disruptions from vessel noise could influence feeding and breeding patterns essential to the health of the stock. Data used in this analysis were collected continuously over 36 days in the summer of 2001 from bottom moored Navy Environmental Acoustic Recording System (EARS) buoys. Results showed a significant difference (P<0.05) in noise level between hours with ships passing and hours without. Metrics for 56 ship passages were analyzed to compare duration of ship passage with duration of maximum received level (MRL) during ship passage. Results of that analysis showed an average ship passage of 29 minutes with average MRL lasting 23% of the ship passage and an average increase of 40dB. Lastly, click counts were made with the Pamguard. Click counts for ship passages were completed for 35 min and 17.5 min before and after the estimated closest point of approach (CPA) for each ship. Results showed a 36% decrease in the number of detectable clicks as a ship approaches when comparing clicks detected at intervals of both 35 minutes before and 17 minutes before the CPA; additionally, 22% fewer clicks were counted 30 min after the ship than 30 min before (results significant at the P=0.01 level). These results indicate a potential change in sperm whale behavior when exposed to large class size vessel traffic (e.g. tankers and container ships) from major shipping lanes. Recommendations for addressing this issue are discussed.

Amphipods of the deep Mississippi Canyon, northern Gulf of Mexico: ecology and bioaccumulation of organic contaminants  

E-Print Network (OSTI)

In five summer cruises during the period 2000-2004, seventy-four box cores were collected from eleven locations from the Mississippi Canyon (480- 2750m, northern Gulf of Mexico), and an adjacent transect (336-2920) to understand the community structure and trophic function of amphipods and for measuring the bioaccumulation of polycyclic aromatic hydrocarbons, (PAHs). Amphipods were discovered to be an important component of the macrofauna of the Mississippi Canyon (40 % of the total faunal abundance). Seventy two species, belonging to nineteen families, were collected from the study area with 61 species from the canyon and only 38 species from the non-Canyon transect. The head of the canyon (480m) was dominated by dense mats (15,880 ind/m2) of a new amphipod (Ampelisca mississippiana). The logarithm of the amphipod abundance decreased linearly with depth. The species diversity (H`) exhibited a parabolic pattern with a maximum at 1100m. The differences in amphipod abundances and biodiversities were correlated with the variation in the amount of available organic matter. The depression in diversity in the canyon head is thought to be competitive exclusion resulting from the dominance by A.mississippiana, but the high species richness is presumed to be a function of the structural complexity of the canyon. Annual secondary production of A. mississippiana was 6.93 g dry wt m-2, based on size-frequency method and corresponding to an estimated univoltine generation from a regression model. The production/biomass ratio (P/B) was 3.11. Production of this magnitude is comparable to shallow marine ampeliscids but are high for the depauperate northern Gulf of Mexico. The effect of the organic contaminants and the bioavailability to the amphipods was determined through measuring the bioaccumulation of the PAHs. The distribution of PAHs in sediments was different from the distribution in the organisms suggesting preferential uptake/depuration or uptake from pore or bottom waters. The average bioaccumulation factor (4.36 ± 2.55) and the biota sediment accumulation factor (0.24±0.13) for the total PAHs by the ampeliscids were within the range reported for other benthic invertebrates. The average bioaccumulation factors were highest for dibenzothiophenes (up to 132) and alkylated PAHs and lowest for parent high molecular weight PAHs.

Empirical vertical structure of density anomaly in the Gulf of Mexico  

E-Print Network (OSTI)

Climatological vertical structure of density anomaly in the Gulf of Mexico is realistically characterized in a form useful for calibration and/or verification of numerical circulation models, employing a new method that allows variable depth and thermocline ventilation. We do this by local flat bottom dynamic analysis based on the primitive equations referred to an isopycnic coordinate system, so that potential density is treated as a conservative property. A global reference column is constructed for use in a dynamic modal decomposition in terms of local vertical structure functions that integrates seafloor depth and station data in a common spectral representation. The dynamic procedure is followed by joint and simple indirect EOF (empirical orthogonal function) analysis of modal coefficients for the complete data set and for binned subsets of the data. The dominant EOFs resemble dynamic modes, but combinations of dynamic modes are observed in EOFs having small contribution to the total variance. Indirect EOF representation of the data appears to have its greatest implications in the physical interpretation of the dynamic system, specifically in the coupling of dynamic modes.

Ship and satellite observations of chlorophyl stocks in interacting cyclone-anticyclone eddy pairs in the western Gulf of Mexico  

SciTech Connect

When anticyclonic eddies shed by the Loop Current of the Gulf of Mexico reach the western margin of the gulf, they influence the surface circulation over the continental slope and rise. Of particular interest is the generation of cyclone (cold-core)- anticyclone (warm-core) pairs when aging Loop Current eddies interact with the continental margin. In this paper the authors describe the physical and biological characteristics of these cyclone-anticyclone pairs. Their objective was to determine how eddy pairs affect the distribution of phytoplankton in the region and how satellite ocean color measurements are applicable to tracing of the eddies. They present shipboard data collected between 1980 and 1982 on the hydrography, chlorophyll stocks, and nutrient concentrations of eddy pairs in the western Gulf of Mexico and compare these data with coastal zone color scanner (CZCS) images collected during the time frame of the cruises. Surface pigment concentrations followed a seasonal cycle, with low concentrations (0.05-0.1 mg m{sup {minus}3}) found within cyclones and anticyclones from April through early November and higher concentrations (>0.1 mg m{sup {minus}3}) found in the winter. CZCS pigment concentrations were locally high in the flow confluence of cyclone-anticyclone pairs. The CZCS imagery shows that some cyclone-anticyclone geometries transport high-chlorophyll shelf water seaward at least 100-200 km off-shelf. 46 figs., 9 figs., 3 tabs.

Ocean thermal energy conversion ecological data report from OSS Researcher in Gulf of Mexico, (GOTEC-01), July 12-23, 1977  

DOE Green Energy (OSTI)

Ecological measurements important for environmental assessment of the effect of an operating Ocean Thermal Energy Conversion plant were initiated in July 1977 at the proposed Gulf of Mexico site off the coasts of Louisiana, Mississippi, Alabama and Florida. The initial cruise of the OSS Researcher, in a joint effort with the Atlantic Oceanic and Meteorological Laboratories (AOML) of the National Oceanic and Atmospheric Administration (NOAA), and Lawrence Berkeley Laboratory (LBL) took place from 12 to 23 July 1977. The measurements were taken at 15 oceanographic stations to a maximum depth of 1000 m. Water was analyzed for trace metals, nutrients and chlorophyll a and ATP. Physical data, salinity and dissolved oxygen measurements were supplied by NOAA-AOML. Two bioassays were carried out using indigenous phytoplankton to estimate the effect of deep water on the rates of /sup 14/CO/sub 2/ uptake of photic zone algae. The Deep Scattering Layer (DSL) was monitored at the site by a continuously recording 12 kHz depth sounder at the Mobile site. This report presents data collected during the cruise.

An Evaluation of the Available Energy Potential of the Gulf Coast Geopressured Zones  

DOE Green Energy (OSTI)

The geopressured zones presently under serious study in the U.S. are tertiary sediments in the Gulf Coastal basin which are water saturated and exhibit pressures significantly greater than hydrostatic. These sediments are primarily shale, interbedded with sandstone. The top of the geopressured zone is frequently near 10,000 ft. or so, and extends to indeterminate depths. The water contained in these zones is at a moderately elevated temperature and, more significantly, appears to contain dissolved methane at near-saturation values. Conceptually, wells drilled into the geopressured zone might be expected to produce water without pumping, due to the high pressures. The dissolved methane could then be separated at the surface and used conventionally as natural gas. The water may contain sufficient heat to provide a useful source of geothermal energy, and the hydraulic energy might also provide useful work. Development of the geopressured/geothermal resource is largely dependent upon production characteristics of geopressured reservoirs. These in turn are intimately related to properties of the formations, and can be defined within reasonable limits.

Radiation dose and risk to recreational fishermen from ingestion of fish caught near eight oil platforms in the Gulf of Mexico  

SciTech Connect

Offshore production of oil and gas is accompanied by a saline wastewater, called produced water. Produced water discharges to the Gulf of Mexico often contain elevated concentrations of radionuclides that occur naturally in the geologic reservoir along with the oil and gas. These radionuclides may accumulate in organisms that live near offshore oil and gas structures. Because recreational fishing in the Gulf of Mexico is concentrated near oil and gas platforms, there is the potential for increased risks to recreational fishermen from the ingestion of radionuclides in fish caught near produced water discharges. This analysis investigated the potential risk to recreational fishermen from radium and lead-210 in offshore produced water discharged to the Gulf of Mexico.

Occurrence of gas hydrate in Oligocene Frio sand: Alaminos Canyon Block 818: Northern Gulf of Mexico  

SciTech Connect

A unique set of high-quality downhole shallow subsurface well log data combined with industry standard 3D seismic data from the Alaminos Canyon area has enabled the first detailed description of a concentrated gas hydrate accumulation within sand in the Gulf of Mexico. The gas hydrate occurs within very fine grained, immature volcaniclastic sands of the Oligocene Frio sand. Analysis of well data acquired from the Alaminos Canyon Block 818 No.1 ('Tigershark') well shows a total gas hydrate occurrence 13 m thick, with inferred gas hydrate saturation as high as 80% of sediment pore space. Average porosity in the reservoir is estimated from log data at approximately 42%. Permeability in the absence of gas hydrates, as revealed from the analysis of core samples retrieved from the well, ranges from 600 to 1500 millidarcies. The 3-D seismic data reveals a strong reflector consistent with significant increase in acoustic velocities that correlates with the top of the gas-hydrate-bearing sand. This reflector extends across an area of approximately 0.8 km{sup 2} and delineates the minimal probable extent of the gas hydrate accumulation. The base of the inferred gas-hydrate zone also correlates well with a very strong seismic reflector that indicates transition into units of significantly reduced acoustic velocity. Seismic inversion analyses indicate uniformly high gas-hydrate saturations throughout the region where the Frio sand exists within the gas hydrate stability zone. Numerical modeling of the potential production of natural gas from the interpreted accumulation indicates serious challenges for depressurization-based production in settings with strong potential pressure support from extensive underlying aquifers.

Low-frequency variability of currents in the deepwater eastern Gulf of Mexico  

E-Print Network (OSTI)

Vertical structure of the low frequency horizontal currents at the northern edge of the Loop Current during eddy shedding events is observed using concurrent hydrographic, moored, and satellite altimetry data from 2005. Dynamic modes are calculated at three deep (~3000 m), full water-column moorings in the eastern Gulf of Mexico. Time-series of the barotropic and first two baroclinic modes are found using a least squares minimization that fits theoretically derived modes to observed moored velocity data. EOF analyses show that the majority of observed variance is explained by a surface-trapped mode that is highly coherent with the temporal amplitudes of the first baroclinic mode, and a lower, but significant percentage of variance is captured in bottom-intensified modes. Amplitudes of the second empirical mode indicate that currents are more coherent in the ocean interior approaching the Loop Current, as more variance is explained by this mode at the southernmost mooring near the Loop Current. A dynamic mode decomposition of the horizontal currents reveals that the barotropic and first baroclinic modes exhibit low frequency variability and eddy time scales of 10 – 40 days. Second baroclinic mode amplitudes show higher frequency variability and shorter time scales. A model utility test for the least squares fit of modeled to observed velocity shows that the second baroclinic mode is useful to the statistical model during 50 – 85 % of the mooring deployment, and is particularly necessary to the model when cyclonic features are present in the study area. The importance of the second baroclinic mode to the model increases significantly closer to the Loop Current. High-speed currents associated with the Loop Current and anticyclones stimulate a strong first baroclinic response, but the second baroclinic mode amplitudes are found to be similar in magnitude to the first baroclinic mode amplitudes at times. This happens episodically and could be an indication of higher order dynamics related to frontal eddies or Loop Current eddy shedding.

Kinematic and Mechanical Reconstruction of Walker Ridge Structures, Deepwater Gulf of Mexico  

E-Print Network (OSTI)

Recent high-resolution seismic imaging has allowed detailed reconstruction of the relationship between fold development and crestal faulting of the Chinook and Cascade folds in the deepwater Gulf of Mexico. Using 3-D seismic and biostratigraphic data, we have found that (1) short wavelength (~2300m), small amplitude folds (~540m) within the upper Cretaceous and upper Jurassic stratigraphic sequences took place no later than the late Jurassic, (2) large wavelength and amplitude fold growth, starting in the early Cretaceous, was produced by salt withdrawal, and (3) periods of increased sedimentation, fold growth, and fault slip occurred during the middle Miocene and late Miocene. Although the dominant stage of long wavelength, large amplitude fold growth started around early Cretaceous, the development of the Cascade and Chinook structures was continuous, punctuated by episodes of accelerated growth during the middle Miocene at rates of 337 and 235 m/Ma in the Cascade and 203 and 230 m/Ma in the Chinook. A later event of accelerated growth occurred during the late Miocene at rates of 1038 m/Ma in the Cascade and 1189 m/Ma in the Chinook. Accompanying fold growth was sedimentation, which was highest at 1949 m/Ma in the Cascade and 2585 m/Ma in the Chinook. Although limb tilt rates varied through fold growth, the highest rates also occurred during the middle Miocene at 0.330 and 0.196 degree/Ma for the Cascade and Chinook, respectively with the development of crestal faults at maximum slip rates of 88 and 90 m/Ma.

GoMRC Website ‘Meta-analysis Report: Land-use and submerged aquatic vegetation change in the Gulf of Mexico  

SciTech Connect

Over the past century, health and spatial extent of seagrasses has decreased dramatically in the Gulf of Mexico. While some of the changes can be explained by direct impacts to the seagrass beds, we hypothesize that changes in the land use in the watersheds can also be correlated with the decline of seagrasses. Through this meta-analysis, we researched historical and compared trends in seagrass populations and land use in five bays and their watersheds within the Gulf of Mexico: Mobile Bay, Perdido Bay, Tampa Bay, Charlotte Harbor, and Galveston Bay. Using both historical records and spatial datasets, we examined land use and seagrass trends in these five areas.

Salinity variations and chemical compositions of waters in the Frio Formation, Texas Gulf Coast. Annual report  

DOE Green Energy (OSTI)

Waters produced from sandstone reservoirs of the deep Frio Formation exhibit spatial variations in chemical composition that roughly coincide with the major tectonic elements (Houston and Rio Grande Embayments, San Marcos Arch) and corresponding depositional systems (Houston and Norias deltas, Greta-Carancahua barrier/strandplain system) that were respectively active along the upper, lower, and middle Texas Coast during Frio deposition. Within an area, salinities are usually depth dependent, and primary trends closely correspond to pore pressure gradients and thermal gradients. Where data are available (mainly in Brazoria County) the increases in TDS and calcium with depth coincide with the zone of albitization, smectite-illite transition, and calcite decrease in shales. Waters have fairly uniform salinities when produced from the same sandstone reservoir within a fault block or adjacent fault blocks with minor displacement. In contrast, stratigraphically equivalent sandstones separated by faults with large displacement usually yield waters with substantially different salinities owing to the markedly different thermal and pressure gradients across the faults that act as barriers to fluid movement.

Anomalous zones in Gulf Coast Salt domes with special reference to Big Hill, TX, and Weeks Island, LA  

Science Conference Proceedings (OSTI)

Anomalous features in Gulf Coast Salt domes exhibit deviations from normally pure salt and vary widely in form from one dome to the next, ranging considerably in length and width. They have affected both conventional and solution mining in several ways. Gas outbursts, insolubles, and potash (especially carnallite) have led to the breakage of tubing in a number of caverns, and caused irregular shapes of many caverns through preferential leaching. Such anomalous features essentially have limited the lateral extent of conventional mining at several salt mines, and led to accidents and even the closing of several other mines. Such anomalous features, are often aligned in anomalous zones, and appear to be related to diapiric processes of salt dome development. Evidence indicates that anomalous zones are found between salt spines, where the differential salt intrusion accumulates other materials: Anhydrite bands which are relatively strong, and other, weaker impurities. Shear zones and fault displacement detected at Big Hill and Weeks Island domes have not yet had any known adverse impacts on SPR oil storage, but new caverns at these sites conceivably may encounter some potentially adverse conditions. Seismic reflection profiles at Big Hill dome have shown numerous fractures and faults in the caprock, and verified the earlier recognition of a major shear zone transecting the entire salt stock and forming a graben in the overlying caprock. Casing that is placed in such zones can be at risk. Knowledge of these zones should create awareness of possible effects rather than preclude the future emplacement of caverns. To the extent possible, major anomalous zones and salt stock boundaries should be avoided. Shear zones along overhangs may be particularly hazardous, and otherwise unknown valleys in the top of salt may occur along shear zones. These zones often can be mapped geophysically, especially with high-resolution seismic techniques.

Statistical nature of cold fronts within the Gulf of Mexico and their potential influence on OTEC operations  

DOE Green Energy (OSTI)

This study was undertaken to quantify selected aspects of cold fronts as they penetrate southward into the Gulf of Mexico region. A need arises to statistically define the nature of these cold fronts since the Department of Energy's Ocean Thermal Energy Conversion (OTEC) program is geared for determining the feasibility of utilizing the temperature difference between the tropical ocean surface and depths of approximately 1500 m for the production of power. However, severe winters are known to significantly decrease the normal sea surface temperature by approximately 7.2/sup 0/F as well as cause deepening of the mixed layer (Leetmaa, 1977). With an OTEC plant operating at efficiencies of only 2 to 3 percent, the plant could become marginally operational during the winter months. Upon the passage of a cold front, the sea surface will exchange heat to the atmosphere through the fluxes of latent and sensible heat. Garstang (1969) has shown that these fluxes can increase more than an order of magnitude upon the passage of a moderate cold front. Long term, greater than 25 years, meteorological data from the National Climatic Center was used as the basis for determining the impact of cold fronts in the gulf of Mexico region. In particular, surface air temperature and wind direction were analyzed daily during the months of December, January, and February. The drop in temperature as well as the directional wind shift were the criteria for the frontal passage. Surface observation data from Tampa and Key West, Florida were used.

Structural restoration of Louann Salt and overlying sediments, De Soto Canyon Salt Basin, northeastern Gulf of Mexico  

E-Print Network (OSTI)

The continental margin of the northeastern Gulf of Mexico is suited for seismic stratigraphic analysis and salt tectonism analysis. Jurassic strata include the Louann Salt on the continental shelf and upper slope of the Destin Dome OCS area, northeastern Gulf of Mexico. These sediments were deposited in a slowly subsiding, stable tectonic environment. Two-dimensional (2-D) seismic data, supplemented with well log, paleontologic and velocity information were used to infer structural and stratigraphic features, especially small faults in the deep part of the De Soto Canyon Salt Basin area. Six sequence boundaries or correlative paleohorizons were interpreted on Landmark seismic interpretation workstation. They are Base of Salt or Equivalent, Top of Salt, Top of Smackover Formation, Top of Cotton Valley Group, Middle Cretaceous sequence boundary, and Top of Upper Cretaceous. Information generated from structural and stratigraphic analysis are used to analyze the evolution of salt movement and salt mechanism in this area. I used a software package Restore (Dan Schultz-Ela and Ken Duncan, 1991) for structural restoration. This program is suitable for extensional terrane. The restoration of one depth section was achieved through steps introduced by Restore. Regional extension, gravity spreading, and gliding are the most important mechanism of salt flow, buoyancy and differential loading mainly contribute to the vertical development of salt structure in this area.

CHARACTERIZING NATURAL GAS HYDRATES IN THE DEEP WATER GULF OF MEXICO: APPLICATIONS FOR SAFE EXPLORATION AND PRODUCTION ACTIVITIES  

Science Conference Proceedings (OSTI)

In 2000, Chevron began a project to learn how to characterize the natural gas hydrate deposits in the deepwater portions of the Gulf of Mexico. A Joint Industry Participation (JIP) group was formed in 2001, and a project partially funded by the U.S. Department of Energy (DOE) began in October 2001. The primary objective of this project is to develop technology and data to assist in the characterization of naturally occurring gas hydrates in the deep water Gulf of Mexico (GOM). These naturally occurring gas hydrates can cause problems relating to drilling and production of oil and gas, as well as building and operating pipelines. Other objectives of this project are to better understand how natural gas hydrates can affect seafloor stability, to gather data that can be used to study climate change, and to determine how the results of this project can be used to assess if and how gas hydrates act as a trapping mechanism for shallow oil or gas reservoirs. During April-September 2002, the JIP concentrated on: Reviewing the tasks and subtasks on the basis of the information generated during the three workshops held in March and May 2002; Writing Requests for Proposals (RFPs) and Cost, Time and Resource (CTRs) estimates to accomplish the tasks and subtasks; Reviewing proposals sent in by prospective contractors; Selecting four contractors; Selecting six sites for detailed review; and Talking to drill ship owners and operators about potential work with the JIP.

The feeding biomechanics of juvenile red snapper (Lutjanus campechanus) from the northwestern Gulf of Mexico  

E-Print Network (OSTI)

Juvenile red snapper are attracted to structure and settle onto low profile reefs, which serve as nursery grounds. Little is known about their life history during this time. However, recent studies from a shell bank in the NW Gulf of Mexico have shown higher growth rates for juveniles located on mud habitats adjacent to low profile reefs, perhaps due to varied prey availability and abundance. To further investigate the habitat needs of juvenile red snapper, individuals were collected from a low profile shell ridge (on-ridge) and adjacent mud areas (off-ridge) on Freeport Rocks, TX, and divided into three size classes (?3.9 cm SL, 4.0-5.9 cm SL, ?6 cm SL). Feeding morphology and kinematics were characterized and compared among size classes and between the two habitats. A dynamic jaw lever model was used to make predictions about feeding mechanics, and kinematic profiles obtained from high-speed videos of prey capture events validated the model’s predictive ability. Model output suggested an ontogenetic shift in feeding morphology from a juvenile feeding mode (more suction) to an adult feeding mode (more biting). Stomach contents revealed a concomitant shift in prey composition that coincided with the ontogenetic shift in feeding mode. The model also predicted that on-ridge juveniles would have faster jaw closing velocities compared to off-ridge juveniles, which had slower, stronger jaws. Analysis of prey capture events indicated that on-ridge juveniles demonstrated greater velocities and larger displacements of the jaws than off-ridge juveniles. Shape analysis was used to further investigate habitat effects on morphology. Off-ridge juveniles differed from on-ridge in possessing a deeper head and body. Results from model simulations, kinematic profiles, personal observations, and shape analysis all complement the conclusion that on-ridge juveniles exhibited more suction feeding behavior, whereas off-ridge juveniles used more biting behavior. Stomach contents demonstrated an early switch to piscivory in off-ridge juveniles compared to on-ridge juveniles, which may account for higher off-ridge growth rates. Habitat disparity, perhaps available prey composition, generated variations in juvenile feeding mechanics and consequently feeding behavior. This disparity may ultimately affect the growth rates and recruitment success of juvenile red snapper from different habitats.

Sulfide distribution in chemosynthetic communities at hydrocarbon seeps in the Gulf of Mexico  

E-Print Network (OSTI)

Dense macrofaunal communities around hydrocarbon seeps in the Gulf of Mexico (GOM) are supported by the activity of chemoautotrophic microorganisms that couple the oxidation of sulfide (H?S) or methane with the fixation of inorganic carbon into organic biomass. The connections and feedbacks between microbial activity and the geochemistry of these communities are not fully understood. The role of geochemistry in fueling microbially mediated processes was assessed by estimating sediment-water interface fluxes of H?S. Gradient driven H?S fluxes were calculated from fine-scale profiles and Fick's first law, for the top centimeter of sediments underlying Beggiatoa mats, tube worm bushes, and control sites. Profiles were obtained using solid-state mercury-gold amalgam microelectrodes capable of measuring O?, H?S, Mn²?, and Fe²? simultaneously via square and cyclic wave voltammetry. Sediment cores were collected from GOM hydrocarbon seeps using the submersible, Johnson Sea Link. Results focused on H?S as very low to undetectable concentrations of Mn²? and Fe²? were measured in porewaters. Lack of O? detection resulted from the high O? demand, which ranged from 0.006 to 0.584 mmol of O? hr?¹ according to estimates based on measured sulfate reduction rates, typical of these environments. Profiles of H?S in cores from Beggiatoa mats showed a consistent sharp increase in concentration across the sediment-water interface with little inter-annual variation, reflecting the ability of Beggiatoa to exploit favorable chemical environments. Profiles in cores collected distally and proximally to tube worm bushes in 1997 and 1998 were generally depleted over the top three to four centimeters, respectively, reflecting the potential for H?S uptake by underlying tube worm "roots". Fluxes in Beggiatoa mats ranged from -4.1 to -123.0 and -7.2 to -213.4 mmol m?² d?¹ in 1997 and 1998, respectively, into the overlying water. H?S flux from cores collected from tube worm bushes ranged from -50.6 to 5.0 and 0 to -240.2 mmol m?² d?¹ in 1997 and 1998, respectively. Variations in H?S profiles and fluxes in Beggiatoa mats, tube worms, and control sites may help delineate the distribution of different community types and their tolerance of what most consider a harsh environment.

Phytoplankton Responses to Mass Coral Spawning in the Flower Garden Banks, Gulf of Mexico  

E-Print Network (OSTI)

Mass coral spawning represents a nutrient input to coral reef systems that for Pacific reefs has been shown to stimulate pelagic and benthic processes. If phytoplankton in the water column over the reef are able to utilize this annual nutrient input, this could potentially alter phytoplankton biomass and community composition, in what is normally a very oligotrophic system. Sampling was performed at East Flower Garden Bank (EFGB), Gulf of Mexico during May, July, and August 2009. The annual coral spawning event occurred there August 11-14, 2009. Samples were collected morning and evening at three depths and analyzed for nutrients, chlorophyll a, accessory pigments, phytoplankton species composition, and carbon, hydrogen, and nitrogen (CHN). During spawning, only small changes in nutrient concentrations were detected. Dissolved inorganic nitrogen (DIN) peaked on the second day of spawning and N:P ratio was highest on 5/28, likely due to particularly phosphate concentration. Chl a biomass was significantly different between sample dates and the biomass increased steadily throughout the spawning period. The contribution of different phytoplankton classes to total chlorophyll a was determined using known pigment algorithms. Prokaryotes were the dominant class across the entire sampling period with 60-80 percent abundance. Trichodesmium spp. was the dominant genus throughout the study and genus specific changes per sample date were seen. On 8/11 and 8/13 two genera contributed the majority of chl a (Trichodesmium spp. and Ceratium spp.; Cylindrotheca spp. and Trichodesmium spp., respectively). Abundance showed variability during spawning with a peak at 11 cells/ml on 8/12. The high abundance of Trichodesmium spp. could indicate N limitation is alleviated at the Flower Garden Banks (FGB). Current literature on coral spawning is limited to studies performed in the Great Barrier Reef, with assessment areas close to a major shoreline. Genera found at EFGB were similar to those found in other reef systems. It cannot be determined if nutrient input increased diversity, as diversity was high prior to spawning as well. Greater increase in available forms of nitrogen would have likely been found several days post major spawning. The FGB were a unique system to study, as they are coral reefs, but are located 200 km offshore. This study provided a snapshot into phytoplankton dynamics as a result of spawning. Changes across the short time scale were seen in biomass and community composition.

RADIATION DOSE AND RISK TO RECREATIONAL FISHERMEN FROM INGESTION OF FISH CAUGHT NEAR EIGHT OIL PLATFORMS IN THE GULF OF MEXICO  

SciTech Connect

Offshore production of oil and gas is accompanied by a saline wastewater, called produced water. Produced water discharges to the Gulf of Mexico often contain elevated concentrations of radionuclides that occur naturally in the geologic reservoir along with the oil and gas. These radionuclides may accumulate in organisms that live near offshore oil and gas structures. Because recreational fishing in the Gulf of Mexico is concentrated near oil and gas platforms, there is the potential for increased risks to recreational fishermen from the ingestion of radionuclides in fish caught near produced water discharges. This analysis investigated the potential risk to recreational fishermen from radium and lead-210 in offshore produced water discharges to the Gulf of Mexico. The assessment used data collected at eight discharging offshore platforms and two reference locations. These data were collected in a USDOE funded project titled ``Environmental and Economic Assessment of Discharges from Gulf of Mexico Region Oil and Gas Operations'', here called the USDOE Field Study. The risk assessments were done to support risk managers in developing regulations and permits for offshore discharges of produced water.

ASSESSING AND FORECASTING, BY PLAY, NATURAL GAS ULTIMATE RECOVERY GROWTH AND QUANTIFYING THE ROLE OF TECHNOLOGY ADVANCEMENTS IN THE TEXAS GULF COAST BASIN AND EAST TEXAS  

SciTech Connect

A detailed natural gas ultimate recovery growth (URG) analysis of the Texas Gulf Coast Basin and East Texas has been undertaken. The key to such analysis was determined to be the disaggregation of the resource base to the play level. A play is defined as a conceptual geologic unit having one or more reservoirs that can be genetically related on the basis of depositional origin of the reservoir, structural or trap style, source rocks and hydrocarbon generation, migration mechanism, seals for entrapment, and type of hydrocarbon produced. Plays are the geologically homogeneous subdivision of the universe of petroleum pools within a basin. Therefore, individual plays have unique geological features that can be used as a conceptual model that incorporates geologic processes and depositional environments to explain the distribution of petroleum. Play disaggregation revealed important URG trends for the major natural gas fields in the Texas Gulf Coast Basin and East Texas. Although significant growth and future potential were observed for the major fields, important URG trends were masked by total, aggregated analysis based on a broad geological province. When disaggregated by plays, significant growth and future potential were displayed for plays that were associated with relatively recently discovered fields, deeper reservoir depths, high structural complexities due to fault compartmentalization, reservoirs designated as tight gas/low-permeability, and high initial reservoir pressures. Continued technology applications and advancements are crucial in achieving URG potential in these plays.

Causes of wetland loss in the coastal central Gulf of Mexico. Volume 2. Technical narrative. Final report  

Science Conference Proceedings (OSTI)

In 1985, the Minerals Management Service initiated an investigation to study the causes of wetland loss in the coastal Gulf of Mexico as part of its Outer Continental Shelf environmental-studies program. The purpose of the two-year study was to investigate the factors that contribute to wetland loss and to determine specifically what percentage of the loss is directly and indirectly related to Federal offshore oil and gas development. The primary goal of the Coastal Effects Program is to delineate the onshore impacts of offshore oil and gas development activities. Volume II provides an introduction to the study, direct impacts of OCS activities, saltwater intrusion, subsidence and sedimentation, and landscape patterns and aerial imagery.

DEEPWATER SUBSEA LIQUID/GAS SEPARATION PROCESS UNDER LIVE OIL PRODUCTION CONDITIONS IN THE GULF OF MEXICO  

Science Conference Proceedings (OSTI)

This report includes technical progress made during the period October 2001 to October 2002. At the end of the first technical progress report the project was moving from feasibility of equipment design work to application of this equipment to the actual site for potential demonstration. The effort focuses on reservoir analysis cost estimations of not only the sub-sea processing unit but also the wells, pipelines, installation costs, operating procedures and economic modeling of the development scheme associated with these items. Geologic risk analysis was also part of the overall evaluation, which is factored into the probabilistic economic analysis. During this period two different potential sites in the Gulf of Mexico were analyzed and one site in Norway was initiated but not completed during the period. A summary of these activities and results are included here.

Deep water deposits of the Tanqua and Laingsburg subbasins, southwest Karoo Basin, South Africa: Analog for the Gulf of Mexico  

Science Conference Proceedings (OSTI)

The Tanqua and Laingsburg subbasins in South Africa had near-contemporaneous formation and filling and contain Permian-age basin-floor and slope fans that display characteristics similar to deposits in the northern Gulf of Mexico. Outcrop area for each subbasin is about 650 km{sup 2} and individual fans range from 150 to 450 km{sup 2} with lateral continuity of individual fans up to 34 km. Both subbasins were influenced in their formation and in the architecture of their deposits by structures and events associated with the Cape Fold Belt. These fans most likely had a single point source which migrated over the time of basin fill. Unrestricted deposition suggests an open basin depositional setting. The Laingsburg subbasin was strongly influenced by the tectonism associated with the Cape Fold Belt. Deposition occurred in a deeper and narrower basin and the deposits, except for the overlying deltaics cannot be correlated with those of the Tanqua subbasin. The two subbasins, while associated with an active margin, were likely filled at slightly different times. Both had a distant source area which led to deposits exhibiting characteristics of a passive margin depositional environment. Understanding the evolution of the subbasins and the tectonic conditions under which the submarine fans were deposited leads to the determination of the mechanisms that influenced the formation of the fans and their resulting architecture. These fans permit detailed studies on their architecture necessary to (1) increase our understanding of fine-grained, {open_quotes}low{close_quotes} sandstone/shale ratio fans, (2) determine influences of paleostructures and tectonics on basin fill, (3) carry out detailed reservoir simulation programs, and (4) make predictive models of deep-water sands in the northern Gulf of Mexico.

Characterization and origins of high-amplitude reflection packets, HARPs, along the Gulf of Mexico depositional profile  

E-Print Network (OSTI)

High amplitude reflection packets (HARPs) refer to sheet-like sand deposits, showing high-amplitude seismic-reflection character, which are thought to be associated with constructional channel systems. Based on observations of Quaternary deposits from the Amazon Fan, HARPs are interpreted to be related to channel avulsion events. The depositional model from the Amazon Fan suggests when levees fail, sediment gravity flows move through the break into interchannel lows, where lack of confinement results in sheet like sand deposits. Based on 2D and 3D seismic data, HARPs from the Gulf of Mexico not only form from updip channel avulsions, but from additional geological processes. In salt withdrawal minibasins, sediment gravity flows encounter an underfilled depocenter, where lack of confinement results in sheet like deposits. After initial spill into an outboard basin and the development of a graded slope equilibrium profile, slope channel complexes develop as conduits for sediment transport. These depositional processes characterize the "fill and spill" model and can result in the creation of HARP-like deposits. At the toe-of-the Sigsbee Escarpment, turbidity currents flow through nickpoints at the seaward edge of the escarpment and become unconfined, resulting in HARP-like deposition on the abyssal floor. Seismically, these deposits are laterally continuous, have low relief, pinchout downdip, and have internal channelization. Erosive, low-relief, discontinuous channels and a low-relief, flat-bottomed trough cut into the TS-HARP deposits. On the outer fan, at the seaward limit of submarine channels, sediment gravity flows will also become unconfined and deposit HARPs. These HARPs typically consist of shingled sheet-like deposits that may form larger scale mounded features. These observations indicate that HARP-like deposits can form from a variety of depositional processes and in variable depositional settings along the Gulf of Mexico depositional profile.

Improved recovery from Gulf of Mexico reservoirs. Volume III (of 4): Characterization and simulation of representative resources. Final report, February 14, 1995--October 13, 1996  

Science Conference Proceedings (OSTI)

Significant innovations have been made in seismic processing and reservoir simulation. In addition, significant advances have been made in deviated and horizontal drilling technologies. Effective application of these technologies along with improved integrated resource management methods offer opportunities to significantly increase Gulf of Mexico production, delay platform abandonments, and preserve access to a substantial remaining oil target for both exploratory drilling and advanced recovery processes. In an effort to illustrate the impact that these new technologies and sources of information can have upon the estimates of recoverable oil in the Gulf of Mexico, additional and detailed data was collected for two previously studied reservoirs: a South March Island reservoir operated by Taylor Energy and Gulf of Mexico reservoir operated by Mobil, whose exact location has been blind-coded at their request, and an additional third representative reservoir in the Gulf of Mexico, the KEKF-1 reservoir in West Delta Block 84 Field. The new data includes reprocessed 2-D seismic data, newly acquired 3-D data, fluid data, fluid samples, pressure data, well test data, well logs, and core data/samples. The new data was used to refine reservoir and geologic characterization of these reservoirs. Further laboratory investigation also provided additional simulation input data in the form of PVT properties, relative permeabilities, capillary pressures, and water compatibility. Geologic investigations were also conducted to refine the models of mud-rich submarine fan architectures used by seismic analysts and reservoir engineers. These results were also used, in part, to assist in the recharacterization of these reservoirs.

Assist in the recovery of bypassed oil from reservoirs in the Gulf of Mexico. Quarterly status report (final), July 1--September 30, 1994  

SciTech Connect

The objective of this research is to assist the recovery of non contacted oil from known reservoirs on the Outer Continental Shelf in the Gulf of Mexico. Mature offshore reservoirs, declining oil reserves, declining production, and other natural forces are accelerating the abandonment of offshore oil resources and production platforms. As these offshore wells are plugged and the platforms are abandoned, an enormous volume of remaining oil will be permanently abandoned. Significant quantities of this oil could be recovered using advanced technologies now available if the resource can be identified. This project will proceed under three broad phases: (1) Analysis -- TORIS level data will be collected on the major fields located in the piercement salt dome province of the Gulf of Mexico Outer Continental Shelf. Representative reservoirs will be studied in detail in order to evaluate undeveloped and attic oil reserve potential. These detailed investigations will be used to calibrate the TORIS level predictive models. The recovery potential of advanced secondary and enhanced oil recovery processes and the exploitation of undeveloped and attic oil zones for salt dome reservoirs in the Gulf of Mexico will be assessed. (2) Supporting Research -- Supporting research will focus on the modification of public domain reservoir simulation models to accurately simulate the conditions encountered in the piercement salt dome province of the Gulf of Mexico. Laboratory research will focus on the development of fluid relationships that will be used in the simulation of miscible and immiscible processes in the project area. (3) Technology Transfer -- A significant effort is planned to transfer the results of this project to potential users of the technology. Technology transfer activities will also provide feedback channels that will help keep the analysis and supporting research focused on the most important problems associated with this project.

Assessment of economic impact of offshore and coastal discharge requirements on present and future operations in the Gulf of Mexico. Final report  

Science Conference Proceedings (OSTI)

The high potential costs of compliance associated with new effluent guidelines for offshore and coastal oil and gas operations could significantly affect the economics of finding, developing, and producing oil and gas in the Gulf of Mexico. This report characterizes the potential economic impacts of alternative treatment and discharge regulations for produced water on reserves and production in Gulf of Mexico coastal, territorial and outer continental shelf (OCS) waters, quantifying the impacts of both recent regulatory changes and possible more stringent requirements. The treatment technologies capable of meeting these requirements are characterized in terms of cost, performance, and applicability to coastal and offshore situations. As part of this analysis, an extensive database was constructed that includes oil and gas production forecasts by field, data on existing platforms, and the current treatment methods in place for produced water treatment and disposal on offshore facilities. This work provides the first comprehensive evaluation of the impacts of alternative regulatory requirements for produced water management and disposal in coastal and offshore areas of the Gulf of Mexico.

Geology and potential uses of the geopressure resources of the Gulf Coast. [6,000 MW-centuries of recoverable electric energy, 200 Tcf of methane  

DOE Green Energy (OSTI)

The US ERDA has supported efforts to evaluate the potential contribution to the national energy supply of geopressured geothermal resources in the Gulf Coast. Efforts include a program of resource assessment and programs to examine utilization of the resource for the production of electricity and as a source of industrial-process heat. Work on resource assessment has suggested the presence of perhaps as much as 6,000 MW-centuries of recoverable electric energy and of 200 Tcf of methane. This program has emphasized finding significantly large sand bodies within the geopressured stratigraphic section in addition to defining the distribution of abnormal fluid pressures and formation temperatures. Regional sand facies analyses conducted thus far indicate five locations in the Frio formation of Central and South Texas where adequately large geopressured geothermal resources may be present. Engineering studies of energy-conversion systems based on total-flow, flashed-steam, and binary-cycle concepts show that development of electric power from the Gulf Coast geopressure resource is technically feasible. Study of use of the resource as process heat in pulp and paper mills and new sugar refineries has shown that these uses also are technically sound. The thermal content of a barrel of geothermal brine can cost as little as 9 mills when credited for recoverable hydraulic energy and methane. The value of heat approaches 50 mills per bbl for certain applications. All programs have pointed out clearly the need for better specific understanding of the resource, especially its dissolved methane content and its ability to produce for tens of years.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

SciTech Connect

The Gulf of Mexico Hydrates Research Consortium was established in 1999 to assemble leaders in gas hydrates research. The group is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station has always included the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. This possibility has recently received increased attention and the group of researchers working on the station has expanded to include several microbial biologists. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments are planned for fall 2005 and center about the use of the vessel M/V Ocean Quest and its two manned submersibles. The subs will be used to effect bottom surveys, emplace sensors and sea floor experiments and make connections between sensor data loggers and the integrated data power unit (IDP). Station/observatory completion is anticipated for 2007 following the construction, testing and deployment of the horizontal line arrays, not yet funded. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA).

Importance of physical processes on near-surface nutrient distributions in summer in the northeastern Gulf of Mexico  

E-Print Network (OSTI)

As part of the northeastern Gulf of Mexico chemical oceanography and hydrography study, data on salinity, nutrients, and surface chlorophyll were collected three times per year over the northeastern Gulf of Mexico along 11 cross-shelf (normal to bathymetry) transects from the Mississippi River Delta to Tampa Bay. The transects covered the shelf from the 10-m to the 1000-m isobath. In all three summers of 1998, 1999, and 2000, eddies over the continental margin induced strong, eastward anticyclonic flows over the outer shelf and slope. This flow strongly affected the distribution of coastal water on the shelf in all three years, drawing Mississippi River water into the circulation along the 1000-m isobath and reversing the normal offshore salinity gradient. The entrainment of low salinity river water resulted in anomalously high nutrient and chlorophyll a concentrations in the upper 10-20 m over the outer shelf and upper slope. This is in contrast to the typically low standing stocks of phytoplankton that occur over deep water in subtropical summertime conditions. Vertical nutrient distributions indicated that there was uplift of mid-depth water to shallower depth caused by the presence of either cyclones, regions of diverging flow at eddy peripheries, or bottom Ekman layer transport. Comparison of near-surface nutrient distributions in the low salinity entrainment features with those in the region of uplifted mid-depth water showed that the intrusion of an anticyclonic secondary eddy onto this subtropical continental margin caused deep water rich in nutrients to rise to depths as shallow as 35 or 10 m depending on the location and the intensity of the anticyclonic and cyclonic eddies. Thus, the impact of both Mississippi River water and anticyclonic and cyclonic eddies on nutrient distribution may be important in enhancing productivity over the study region during summer. On average, during each summer, the amount of nitrate reaching the outer shelf and slope in the nutrient-depleted, low-salinity river water transported by eddy circulation, provided 15 to 32 % as much nitrate as came from uplifted mid-depth water from either cyclones, diverging flow at eddy peripheries, or bottom Ekman layer transport.

Observations on the flow structures and transport in a warm-core ring in the Gulf of Mexico  

E-Print Network (OSTI)

This study presents several new observations from the study of a warm-core ring (WCR) in the Gulf of Mexico based on the ECCO2 global ocean simulation. Using Lagrangian coherent structures (LCS) techniques to investigate this flow reveals a pattern of transversely intersecting LCS in the mixed layer of the WCR which experiences consistent stretching behavior over a large region of space and time. A detailed analysis of this flow region leads to an analytical model velocity field which captures the essential elements that generate the transversely intersecting LCS. The model parameters are determined from the WCR and the resulting LCS show excellent agreement with those observed in the WCR. The three-dimensional transport behavior which creates these structures relies on the small radial outflow which is present in the mixed layer and is not seen below the pycnocline, leading to a sharp change in the character of the LCS at the bottom of the mixed layer. The flow behavior revealed by the LCS limits fluid excha...

LOW TEMPERATURE X-RAY DIFFRACTION STUDIES OF NATURAL GAS HYDRATE SAMPLES FROM THE GULF OF MEXICO  

SciTech Connect

Clathrate hydrates of methane and other small alkanes occur widespread terrestrially in marine sediments of the continental margins and in permafrost sediments of the arctic. Quantitative study of natural clathrate hydrates is hampered by the difficulty in obtaining pristine samples, particularly from submarine environments. Bringing samples of clathrate hydrate from the seafloor at depths without compromising their integrity is not trivial. Most physical property measurements are based on studies of laboratory-synthesized samples. Here we report X-ray powder diffraction measurements of a natural gas hydrate sample from the Green Canyon, Gulf of Mexico. The first data were collected in 2002 and revealed ice and structure II gas hydrate. In the subsequent time the sample has been stored in liquid nitrogen. More recent X-ray powder diffraction data have been collected as functions of temperature and time. This new data indicates that the larger sample is heterogeneous in ice content and shows that the amount of sII hydrate decreases with increasing temperature and time as expected. However, the dissociation rate is higher at lower temperatures and earlier in the experiment.

Using orbital altimetry and ocean color to characterize habitat of sperm whales in the Gulf of Mexico  

E-Print Network (OSTI)

On Mesoscale Population Study cruises during summers 2004 and 2005 aboard the sailboat Summer Breeze, researchers from the Sperm Whale Seismic Study (SWSS) surveyed for sperm whales along the continental slope of the northern Gulf of Mexico. SWSS scientists tracked 35 groups of whales during these two summers, recording locations where they did and did not encounter whales. Whales were encountered during both summers at approximately the same frequency (19 groups in 38 survey days in 2004; 16 groups in 29 survey days in 2005), but fluke photo-identifications indicated that 85% of individuals encountered during summer 2005 had never been previously identified in the Gulf throughout 10 years of cetacean research. Composition and distribution of these groups also varied between summers. Oceanographic conditions at the edge of the continental shelf differed between 2004 and 2005, which may have modified the usual trophic cascade that begins with near-surface primary production to create local aggregations of prey at the depths where sperm whales forage. Sperm whales are apex, mesopelagic predators, but have been shown to associate with surface primary productivity over large spatial scales and time scales of months to years. The purpose of this thesis was to look for relationships between sperm whale presence and surface oceanography on smaller spatial and shorter temporal scales. Surface ocean color from NASA’s Moderate Imaging Spectroradiometer (MODIS) and surface dynamic height from NASA’s Earth orbital altimeters were evaluated to assess habitat occupied by sperm whales. Passive acoustic monitoring along transect lines for sperm whale clicks permitted determination of sperm whale presence and absence. Sperm whale encounters were in general associated with negative sea surface height and enhanced sea surface chlorophyll (SSC), especially in or near areas where local SSC anomaly was produced by cyclone induced upwelling of nutrients or from coastal water advected off-margin. During summer 2004, SSC was generally high all along the upper continental slope whereas summer 2005 saw relatively low SSC along the upper continental slope. Whales encountered in this study were most highly correlated with SSC two weeks after the initial development of locally highest-SSC anomalies.

Salt Mechanics Primer for Near-Salt and Sub-Salt Deepwater Gulf of Mexico Field Developments  

Science Conference Proceedings (OSTI)

The Gulf of Mexico (GoM) is the most active deepwater region in the world and provides some of the greatest challenges in scope and opportunity for the oil and gas industry. The complex geologic settings and significant water and reservoir depths necessitate high development costs, in addition to requiring innovating technology. The investment costs are substantial: because of the extreme water depths (up to 8000 feet) and considerable reservoir depths (to 30,000 feet below mudline), the cost of drilling a single well can be upwards of 50 to 100 million dollars. Central, therefore, to successful economic exploitation are developments with a minimum number of wells combined with a well service lifetime of twenty to thirty years. Many of the wells that are planned for the most significant developments will penetrate thick salt formations, and the combined drilling costs for these fields are estimated in the tens of billions of dollars. In May 2001, Sandia National Laboratories initiated a Joint Industry Project focused on the identification, quantification, and mitigation of potential well integrity issues associated with sub-salt and near-salt deepwater GoM reservoirs. The project is jointly funded by the DOE (Natural Gas and Oil Technology Partnership) and nine oil companies (BHP Billiton Petroleum, BP, ChevronTexaco, Conoco, ExxonMobil, Halliburton, Kerr-McGee, Phillips Petroleum, and Shell). This report provides an assessment of the state of the art of salt mechanics, and identifies potential well integrity issues relevant to deepwater GoM field developments. Salt deformation is discussed and a deformation mechanism map is provided for salt. A bounding steady-state strain rate contour map is constructed for deepwater GoM field developments, and the critical issue of constraint in the subsurface, and resultant necessity for numerical analyses is discussed.

An analysis of tissues for total PCB and planar PCB concentrations in marine mammals stranded along the Gulf of Mexico  

E-Print Network (OSTI)

New methods developed in this study based upon extracting blubber by the maceration of the tissue in methylene chloride and subjecting the resulting extract to gel-permeation chromatography, provided a quick, reliable alternative to classical extraction and separation methods used for analysis of organochlorine residues in marine mammal tissues. Due to the lipophilic nature of PCBS, tissues high in lipid content, such as blubber and melon, give the best estimation of total body burden for the contaminants analyzed. Toxic Equivalents (TEQS) and baseline concentrations of total and planar PCBs in Atlantic bottlenose dolphins (Tursiops truncatus) which stranded along the Gulf of Mexico were determined in this study. The data suggests that concentrations of total PCBs and planar PCBs are not correlated, hence samples must be analyzed for both compounds in comprehensive studies. In the present study, PCB levels were statistically similar in 3 marine mammal species investigated (T. truncates, Stenella sp. , and Peponocephala electra). There appeared to be little correlation between PCB concentrations and stranding condition, stranding location or stranding year; however, a strong correlation was observed between the levels of PCBS, and the maturity and gender of the specimens analyzed. Male bottlenose dolphins accumulate PCBs throughout their lives as they mature, while females dolphins, once sexually mature, offload much of their body burdens of PCBs to their calves both transplacentally and through lactation. This trend would suggest that PCBs can be used as a chemical tracer in evaluating some biological and reproductive parameters of this species. Finally, preferential distribution of PCBs in different body blubber areas of T. truncatus was not observed in this study. This observation is possibly due to the homogeneous distribution of lipids in the thin blubber layer of these animals.

Salt Control on Sedimentary Processes in Early Pleistocene: Ship Shoal South Addition Blocks 349-358, Gulf of Mexico.  

E-Print Network (OSTI)

The interpretation of 3D seismic data from Ship Shoal South Addition Blocks 349-358, Gulf of Mexico shows a complex interaction between salt, faults, and sedimentary strata. Reconstruction of the geometry of early Pliestocene (about 3.65 Ma) through recent salt and associated sediments reveals the evolution of a supralobal basin in the study area. The basin depocenter shifted from the northeastern part to the center of the study area through time. A small, bulb-shaped, salt-stock structure occurs in the northwest, and a salt sheet structure is present in the southeastern part of the study area. Those structures are part of a pennant-shaped structure bounded by counter regional faults trending northeastward. Salt movements created instability and triggered extensive faulting of the overlying strata. Three-dimensional reconstruction suggests that salt blocked the sediment during the early Pleistocene. The sediment was diverted around the salt high on both east and west sides of the salt body to the southwest and southeast. Stratigraphic interpretation of the interval between 1.35 Ma and 1.95 Ma led to the identification of a highstand systems tract (HST), a transgressive systems tract(TST), and two lowstand systems tracts (LST). The strata are developed normally in the depocenter area, whereas the strata at the basin margin were deformed by salt movement and faulting. Each systems tract is uniquely associated with a certain seismic facies. Three seismic facies were identified associated with LST, TST, and HST. Additionally, seismic sections reveal channel geometries in the LST. Seismic attribute analysis elucidates facies distribution in the systems tracts. Because of its ability to move, to divert sediment, to create instability, and to block sediment transport pathways, salt exercises the main control on the sedimentary processes in the study area.

A Closer Look at Salt, Faults, and Gas in the Northwestern Gulf of Mexico with 2-D Multichannel Seismic Data  

E-Print Network (OSTI)

The sedimentary wedge of the northern Gulf of Mexico is extensively deformed and faulted by salt tectonics. Industry 2-D multichannel seismic data covering a large area (33,800 km2) of the lower Texas continental slope [96 degrees 40'- 93 degrees 40'W; 27 degrees 10N - 26 degrees N] were examined to evaluate the interplay of salt, faults and gas. Seismic interpretation revealed the study area has two different styles of faulting and two different types of salt bodies that vary east to west. The eastern region of the study area has a thin sedimentary section and a massive, nearly continuous salt sheet characterized by minibasins and local salt highs. Faulting in this area appears to be the result of salt tectonism. The western region of the study area has a thick sedimentary wedge, and a few isolated salt diapirs. Long, linear faults are parallel to slope and imply some degree of gravitation sliding. The difference in faulting styles and salt bodies can be attributed to different depositional environments, different styles and amounts of sediment loading and different amounts of salt initially deposited. While there is a widespread occurrence of gas throughout the study area, little evidence of continuous bottom simulating reflectors (BSRs), a widely accepted geophysical indicator of gas hydrate, has been found. The gas hydrate stability zone (GHSZ) was modeled to provide information on the thickness and variability of the stability zone, and provide a baseline in a search for BSRs. The dataset was analyzed for multiple seismic expressions of BSRs, however only a few small and isolated examples were found. Potential fluid escape structures were seen in the seismic data. Despite the great number of potential features found in the seismic data only seven active seeps were found in a seep study by I. R. MacDonald. Seeps were seen in far less abundance than the number of seeps found offshore Louisiana. This may imply a lack of source offshore Texas.

Wilcox sandstone reservoirs in the deep subsurface along the Texas Gulf Coast: their potential for production of geopressured geothermal energy. Report of Investigations No. 117  

DOE Green Energy (OSTI)

Regional studies of the lower Eocene Wilcox Group in Texas were conducted to assess the potential for producing heat energy and solution methane from geopressured fluids in the deep-subsurface growth-faulted zone. However, in addition to assembling the necessary data for the geopressured geothermal project, this study has provided regional information of significance to exploration for other resources such as lignite, uranium, oil, and gas. Because the focus of this study was on the geopressured section, emphasis was placed on correlating and mapping those sandstones and shales occurring deeper than about 10,000 ft. The Wilcox and Midway Groups comprise the oldest thick sandstone/shale sequence of the Tertiary of the Gulf Coast. The Wilcox crops out in a band 10 to 20 mi wide located 100 to 200 mi inland from the present-day coastline. The Wilcox sandstones and shales in the outcrop and updip shallow subsurface were deposited primarily in fluvial environments; downdip in the deep subsurface, on the other hand, the Wilcox sediments were deposited in large deltaic systems, some of which were reworked into barrier-bar and strandplain systems. Growth faults developed within the deltaic systems, where they prograded basinward beyond the older, stable Lower Cretaceous shelf margin onto the less stable basinal muds. Continued displacement along these faults during burial resulted in: (1) entrapment of pore fluids within isolated sandstone and shale sequences, and (2) buildup of pore pressure greater than hydrostatic pressure and development of geopressure.

Environmental Assessment: Geothermal Energy Geopressure Subprogram. Gulf Coast Well Drilling and Testing Activity (Frio, Wilcox, and Tuscaloosa Formations, Texas and Louisiana)  

DOE Green Energy (OSTI)

The Department of Energy (DOE) has initiated a program to evaluate the feasibility of developing the geothermal-geopressured energy resources of the Louisiana-Texas Gulf Coast. As part of this effort, DOE is contracting for the drilling of design wells to define the nature and extent of the geopressure resource. At each of several sites, one deep well (4000-6400 m) will be drilled and flow tested. One or more shallow wells will also be drilled to dispose of geopressured brines. Each site will require about 2 ha (5 acres) of land. Construction and initial flow testing will take approximately one year. If initial flow testing is successful, a continuous one-year duration flow test will take place at a rate of up to 6400 m{sup 3} (40,000 bbl) per day. Extensive tests will be conducted on the physical and chemical composition of the fluids, on their temperature and flow rate, on fluid disposal techniques, and on the reliability and performance of equipment. Each project will require a maximum of three years to complete drilling, testing, and site restoration.

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

SciTech Connect

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

Salt Tectonics and Its Effect on Sediment Structure and Gas Hydrate Occurrence in the Northwestern Gulf of Mexico from 2-D Multichannel Seismic Data  

E-Print Network (OSTI)

This study was undertaken to investigate mobile salt and its effect on fault structures and gas hydrate occurrence in the northwestern Gulf of Mexico. Industry 2-D multichannel seismic data were used to investigate the effects of the salt within an area of 7,577 mi^2 (19,825 km^2) on the Texas continental slope in the northwestern Gulf of Mexico. The western half of the study area is characterized by a thick sedimentary wedge and isolated salt diapirs whereas the eastern half is characterized by a massive and nearly continuous salt sheet topped by a thin sedimentary section. This difference in salt characteristics marks the edge of the continuous salt sheets of the central Gulf of Mexico and is likely a result of westward decline of original salt volume. Beneath the sedimentary wedge in the western part of the survey, an anomalous sedimentary package was found, that is described here as the diapiric, gassy sediment package (DGSP). The DGSP is highly folded at the top and is marked by tall, diapiric features. It may be either deformed shale or the toe of a complex thrust zone detaching the sedimentary wedge from deeper layers. The dataset was searched for the occurrence of bottom simulating reflectors (BSRs), as they are widely accepted as a geophysical indicator of gas trapped beneath gas hydrate deposits, which are known to occur farther east in the Gulf. Although, many seismic signatures were found that suggest widespread occurrence of gas within the upper sediment column, few BSRs were found. Even considering non-traditional definitions of BSRs, only a few occurrences of patchy and isolated BSRs features were identified. The lack of traditional BSRs is likely the result of geologic conditions that make it difficult to recognize gas hydrate deposits. These factors include: (1) unfavorable layer geometries, (2) flow of warm brines from depth, (3) elevated geotherms due to the thermogenic properties of salt and its varying thickness, and (4) widespread low porosity and permeability sediments within the gas hydrate stability zone.

Gas injection as an alternative option for handling associated gas produced from deepwater oil developments in the Gulf of Mexico  

E-Print Network (OSTI)

The shift of hydrocarbon exploration and production to deepwater has resulted in new opportunities for the petroleum industry(in this project, the deepwater depth greater than 1,000 ft) but also, it has introduced new challenges. In 2001,more than 999 Bcf of associated gas were produced from the Gulf of Mexico, with deepwater associated gas production accounting for 20% of this produced gas. Two important issues are the potential environmental impacts and the economic value of deepwater associated gas. This project was designed to test the viability of storing associated gas in a saline sandstone aquifer above the producing horizon. Saline aquifer storage would have the dual benefits of gas emissions reduction and gas storage for future use. To assess the viability of saline aquifer storage, a simulation study was conducted with a hypothetical sandstone aquifer in an anticlinal trap. Five years of injection were simulated followed by five years of production (stored gas recovery). Particular attention was given to the role of relative permeability hysteresis in determining trapped gas saturation, as it tends to control the efficiency of the storage process. Various cases were run to observe the effect of location of the injection/production well and formation dip angle. This study was made to: (1) conduct a simulation study to investigate the effects of reservoir and well parameters on gas storage performance; (2) assess the drainage and imbibition processes in aquifer gas storage; (3) evaluate methods used to determine relative permeability and gas residual saturation ; and (4) gain experience with, and confidence in, the hysteresis option in IMEX Simulator for determining the trapped gas saturation. The simulation results show that well location and dip angle have important effects on gas storage performance. In the test cases, the case with a higher dip angle favors gas trapping, and the best recovery is the top of the anticlinal structure. More than half of the stored gas is lost due to trapped gas saturations and high water saturation with corresponding low gas relative permeability. During the production (recovery) phase, it can be expected that water-gas production ratios will be high. The economic limit of the stored gas recovery will be greatly affected by producing water-gas ratio, especially for deep aquifers. The result indicates that it is technically feasible to recover gas injected into a saline aquifer, provided the aquifer exhibits the appropriate dip angle, size and permeability, and residual or trapped gas saturation is also important. The technical approach used in this study may be used to assess saline aquifer storage in other deepwater regions, and it may provide a preliminary framework for studies of the economic viability of deepwater saline aquifer gas storage.

Development of an assessment methodology for geopressured zones of the upper Gulf Coast based on a study of abnormally pressured gas fields in south Texas  

DOE Green Energy (OSTI)

Detailed study of the producing gas fields in south Texas has identified a total of 47 abnormally pressured fields in a six-county area including Hidalgo, Brooks, Cameron, Willacy, Kenedy, and Live Oak Counties. An assessment methodology for assessing the potential of the deep geopressured zone in south Texas as an energy resource was developed, based on investigation of the reservoir parameters of these fields. This methodology is transferrable to broad areas of the Gulf Coast. The depth of the geopressured zone in the study area ranges from 7000 ft in western Hidalgo to 12,000 ft in central Cameron County. Temperature data from within the fields, corrected to undisturbed reservoir values, yields a 300/sup 0/F isogeothermal surface at depths from 10,500 ft to 17,000 ft over the study area. The question of fluid deliverability was found to be paramount in determining the potential of the geopressure-geothermal resource as a practical source of energy. The critical parameter is the effective reservoir permeability throughout the study region. Individual fields were assessed for their potential to produce large quantities of geothermal fluid based on reservoir study and detailed geological investigation. Five locations within the study region have been selected as potential candidates for further evaluation and possible eventual testing. Based on investigation of permeability and temperature, the upper limit of fluid temperature likely to be produced in the lower south Texas study region is 300/sup 0/F. In Live Oak County, the possibility of producing fluid at higher temperatures is somewhat improved, with a reasonable possibility of producing fluid at 350/sup 0/ to 375/sup 0/F.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

Science Conference Proceedings (OSTI)

A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has already succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to innovate research methods and construct necessary instrumentation. As funding for this project, scheduled to commence December 1, 2002, had only been in place for less than half of the reporting period, project progress has been less than for other reporting periods. Nevertheless, significant progress has been made and several cruises are planned for the summer/fall of 2003 to test equipment, techniques and compatibility of systems. En route to reaching the primary goal of the Consortium, the establishment of a monitoring station on the sea floor, the following achievements have been made: (1) Progress on the vertical line array (VLA) of sensors: Software and hardware upgrades to the data logger for the prototype vertical line array, including enhanced programmable gains, increased sampling rates, improved surface communications, Cabling upgrade to allow installation of positioning sensors, Incorporation of capability to map the bottom location of the VLA, Improvements in timing issues for data recording.

Ocean thermal energy conversion preliminary data report for the November 1977 GOTEC-02 cruise to the Gulf of Mexico Mobile Site  

DOE Green Energy (OSTI)

This is the second in a series of preliminary data reports from cruises to potential Ocean Thermal Energy Conversion (OTEC) sites in the Gulf of Mexico. The data are from the GOTEC-02 cruise to a site at approximately 29/sup 0/N, 88/sup 0/W, the Mobile Site. Twelve oceanographic stations were visited. Due to bad weather, the results are scanty. The reader will note that much of the data is questionable. Current meter results are presented elsewhere (Molinari, Hazelworth and Ortman, 1979). Determinations of the biomass indicators - chlorophyll a, phaeophytins and adenosine triphosphate - and zooplankton, are presented. Results were generally those that might have been predicted from previous studies in the area.

The Combined Effect of Ocean Acidification and Euthrophication on water pH and Aragonite Saturation State in the Northern Gulf of Mexico  

E-Print Network (OSTI)

Rising atmospheric carbon dioxide (CO2) concentrations are increasing the rate at which anthropogenic CO2 is accumulating in the ocean, and thereby acidifying ocean water. However, accumulation of anthropogenic CO2 is not the only process affecting coastal oceans. Anthropogenic inputs of nutrients to coastal waters can result in massive algal blooms, a process known as eutrophication. Microbial consumption of this organic matter depletes bottom waters of oxygen and increases acidity through the release of CO2. This study assesses the synergistic effect of ocean acidification and eutrophication in the coastal ocean using data from six cruises to the northern Gulf of Mexico. In addition, this study investigates the effect of the 2011 Mississippi River flood on coastal pH and aragonite saturation states. Data from a model simulation using data collected from the northern Gulf of Mexico indicates that eutrophication is contributing to acidification of subsurface waters and plays a larger role than acidification from atmospheric CO2 uptake. Furthermore, results from the model simulation show that the decrease in pH since the industrial era is 0.04 units greater than expected from ocean acidification and eutrophication combined. The additional decrease was attributed to the reduced buffering capacity of the region and may be related to the uptake of atmospheric CO2 into O2-depleted and CO2-enriched waters, the addition of atmospheric CO2 into O2-rich and CO2-poor waters, the input of CO2 via respiration into waters in equilibrium with high atmospheric CO2, or a combination of all three processes.

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

E-Print Network (OSTI)

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