FINAL TECHNICAL REPORT, U.S. Department of Energy: Award No. DE-EE0002855 "Demonstrating the Commercial Feasibility of Geopressured-Geothermal Power Development at Sweet Lake Field - Cameron Parish, Louisiana"  

Science Conference Proceedings (OSTI)

The goal of the project was to demonstrate the commercial feasibility of geopressured-geothermal power development by exploiting the extraordinarily high pressured hot brines know to exist at depth near the Sweet Lake oil and gas field in Cameron Parish, Louisiana. The existence of a geopressured-geothermal system at Sweet Lake was confirmed in the 1970's and 1980's as part of DOE's Geopressured-Geothermal Program. That program showed that the energy prices at the time could not support commercial production of the resource. Increased electricity prices and technological advancements over the last two decades, combined with the current national support for developing clean, renewable energy and the job creation it would entail, provided the justification necessary to reevaluate the commercial feasibility of power generation from this vast resource.

Analysis of ecological effects of geopressured-geothermal resource development. Geopressured-geothermal technical paper No. 4  

DOE Green Energy (OSTI)

The activities involved in geopressured-geothermal resource production are identified and their ecological impacts are discussed. The analysis separates those activites that are unique to geopressured-geothermal development from those that also occur in oil and gas and other resource developments. Of the unique activities, those with the greatest potential for serious ecological effect are: (1) accidental brine discharge as a result of a blowout during well drilling; (2) subsidence; (3) fault activation and enhanced seismicity; and (4) subsurface contamination of water, hydrocarbon, and mineral reservoirs. Available methods to predict and control these effects are discussed.

Geopressured-geothermal development and coastal subsidence in Louisiana  

DOE Green Energy (OSTI)

Elevation changes at the Parcperdue geopressured-geothermal test site in southwestern Louisiana range from 0.8 to 0.16 in/y (+2 to -4 mm/y) and reflect natural base-line movements associated with salt dome growth and the compaction of thick, recent sediments. Natural variation is the primary cause of greater movement at the nearby Rockefeller Refuge geopressured-geothermal test site where base-line movement rates range from -0.43 to -0.55 in/y (-12 to -14 mm/y). Holocene sediments in the coastal marshlands at Rockefeller Refuge are more susceptible to compactional subsidence than upland Pleistocene formations at Parcperdue. Anomalous subsidence at both test sites coincided with site preparation and well drilling and may have been related to loading of surficial soils by the weight of drilling equipment. Elevation changes monitored after drilling and during formation testing were consistent with base-line subsidence rates, indicating that loading was temporary. Anomalous base-line subsidence rates coinciding with areas of historical fluid withdrawal indicate that these effects may outweigh the effects of present geopressured-geothermal development.

Geopressured geothermal drilling and completions technology development needs  

DOE Green Energy (OSTI)

Geopressured geothermal formations found in the Texas and Louisiana gulf coast region and elsewhere have the potential to supply large quantities of energy in the form of natural gas and warm brine (200 to 300/sup 0/F). Advances are needed, however, in hardware technology, well design technology, and drilling and completion practices to enable production and testing of exploratory wells and to enable economic production of the resource should further development be warranted. This report identifies needed technology for drilling and completing geopressured geothermal source and reinjection wells to reduce the cost and to accelerate commercial recovery of this resource. A comprehensive prioritized list of tasks to develop necessary technology has been prepared. Tasks listed in this report address a wide range of technology needs including new diagnostic techniques, control technologies, hardware, instrumentation, operational procedure guidelines and further research to define failure modes and control techniques. Tasks are organized into the functional areas of well design, drilling, casing installation, cementing, completions, logging, brine reinjection and workovers.

Geopressured geothermal bibliography (Geopressure Thesaurus)  

DOE Green Energy (OSTI)

This thesaurus of terminology associated with the geopressured geothermal energy field has been developed as a part of the Geopressured Geothermal Information System data base. A thesaurus is a compilation of terms displaying synonymous, hierarchical, and other relationships between terms. These terms, which are called descriptors, constitute the special language of the information retrieval system, the system vocabulary. The Thesaurus' role in the Geopressured Geothermal Information System is to provide a controlled vocabulary of sufficient specificity for subject indexing and retrieval of documents in the geopressured geothermal energy field. The thesauri most closely related to the Geopressure Thesaurus in coverage are the DOE Energy Information Data Base Subject Thesaurus and the Geothermal Thesaurus being developed at the Lawrence Berkeley Laboratory (LBL). The Geopressure Thesaurus differs from these thesauri in two respects: (1) specificity of the vocabulary or subject scope and (2) display format.

Louisiana Gulf Coast seismicity induced by geopressured-geothermal well development  

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.

Variable pressure supercritical Rankine cycle for integrated natural gas and power production from the geopressured geothermal resource  

DOE Green Energy (OSTI)

A small-scale power plant cycle that utilizes both a variable pressure vaporizer (heater) and a floating pressure (and temperature) air-cooled condenser is described. Further, it defends this choice on the basis of classical thermodynamics and minimum capital cost by supporting these conclusions with actual comparative examples. The application suggested is for the geopressured geothermal resource. The arguments cited in this application apply to any process (petrochemical, nuclear, etc.) involving waste heat recovery.

Design and operation of a geopressurized-geothermal hybrid cycle power plant  

DOE Green Energy (OSTI)

Geopressured-geothermal resources can contribute significantly to the national electricity supply once technical and economic obstacles are overcome. Power plant performance under the harsh conditions of a geopressured resource was unproven, so a demonstration power plant was built and operated on the Pleasant Bayou geopressured resource in Texas. This one megawatt facility provided valuable data over a range of operating conditions. This power plant was a first-of-a-kind demonstration of the hybrid cycle concept. A hybrid cycle was used to take advantage of the fact that geopressured resources contain energy in more than one form -- hot water and natural gas. Studies have shown that hybrid cycles can yield thirty percent more power than stand-alone geothermal and fossil fuel power plants operating on the same resource. In the hybrid cycle at Pleasant Bayou, gas was burned in engines to generate electricity directly. Exhaust heat from the engines was then combined with heat from the brine to generate additional electricity in a binary cycle. Heat from the gas engine was available at high temperature, thus improving the efficiency of the binary portion of the hybrid cycle. Design power output was achieved, and 3445 MWh of power were sold to the local utility over the course of the test. Plant availability was 97.5% and the capacity factor was over 80% for the extended run at maximum power production. The hybrid cycle power plant demonstrated that there are no technical obstacles to electricity generation at Pleasant Bayou. 14 refs., 38 figs., 16 tabs.

Industry participation in DOE-sponsored geopressured geothermal resource development. Final report, 1 September 1977-30 April 1979  

DOE Green Energy (OSTI)

A series of DOE/Industry forums were carried out to keep industry advised of the DOE program to develop the geopressured geothermal resources of the Gulf Coast. A total of eighteen meetings were held with registered attendance of 621 representing a good cross section of industry, state, and federal agencies. An Overview Group and four working subgroups - site selection, drilling and testing, environmental/laboratory research, and legal institutional were established to subdivide the DOE programs into areas of interest and expertise. During the contract period three overview, four site selection, three drilling and testing, five environmental/laboratory research and three legal/institutional meetings have been conducted. Interest in and attendance at the meetings continue to grow reflecting increased industry contact with the DOE Geopressured Geothermal Resource Development Program. Two other studies were carried out for DOE under this contract; a Salt Water Disposal Study and an Industry Survey to evaluate the DOE Resource Development Program. The Salt Water Disposal Study reviewed subsurface salt water disposal experience on the Texas and Louisiana Gulf Coast. This preliminary study concluded that subsurface brine disposal should be possible in the areas of interest with adequate evaluation of the geology of each area and a well designed and constructed surface and subsurface facility. The industry survey indicated general satisfaction with the technical design of the resource evaluation program but felt the program should be moving faster.

Results from geopressured-geothermal subsidence studies  

DOE Green Energy (OSTI)

Benchmark networks have been installed around each of the US Department of Energy geopressured-geothermal test sites in southwestern Louisiana. These networks are periodically surveyed to detect subsidence which may be attributable to depressurization of the geopressured-geothermal reservoirs. The acquired leveling data have been adjusted to account for regional base-line movement determined in another study. The effects of geopressured-geothermal development can only be assessed after carefully examining other potential causes of subsidence. The histories of oil and gas production and ground-water withdrawal around the geopressured-geothermal test site at Parcperdue indicate that oil, gas, and ground-water production may contribute much more to anomalous subsidence than recent geopressured-geothermal brine production. A trend-surface analysis of leveling data for the Parcperdue test site allowed for the separation of a regional component of movement attributable to uplift in the Iberian structural axis to the east and subsidence above a Pleistocene depocenter to the west of the test site. Residual deviations from the regional trend may be associated with the temporary loading and compaction of surface soils caused by the weight of drilling equipment and with ground-water withdrawal.

Geopressured-geothermal well activities in Louisiana  

DOE Green Energy (OSTI)

Since September 1978, microseismic networks have operated continuously around US Department of Energy (DOE) geopressured-geothermal well sites to monitor any microearthquake activity in the well vicinity. Microseismic monitoring is necessary before flow testing at a well site to establish the level of local background seismicity. Once flow testing has begun, well development may affect ground elevations and/or may activate growth faults, which are characteristic of the coastal region of southern Louisiana and southeastern Texas where these geopressured-geothermal wells are located. The microseismic networks are designed to detest small-scale local earthquakes indicative of such fault activation. Even after flow testing has ceased, monitoring continues to assess any microearthquake activity delayed by the time dependence of stress migration within the earth. Current monitoring shows no microseismicity in the geopressured-geothermal prospect areas before, during, or after flow testing.

DOE Green Energy (OSTI)

Information collected and analyzed for a preliminary environmental analysis of geopressured geothermal prospect areas in Colorado and DeWitt Counties, Texas is presented. Specific environmental concerns for each geopressured geothermal prospect area are identified and discussed. Approximately 218 km/sup 2/(85 mi/sup 2/) were studied in the vicinity of each prospect area to: (1) conduct an environmental analysis to identify more and less suited areas for geopressured test wells; and (2) provide an environmental data base for future development of geopressured geothermal energy resources. A series of maps and tables are included to illustrate environmental characteristics including: geology, water resources, soils, current land use, vegetation, wildlife, and meteorological characteristics, and additional relevant information on cultural resources, power- and pipelines, and regulatory agencies. A series of transparent overlays at the scale of the original mapping has also been produced for the purposes of identifying and ranking areas of potential conflict between geopressured geothermal development and environmental characteristics. The methodology for ranking suitability of areas within the two prospect areas is discussed in the appendix. (MHR)

Potential environmental hazards associated with geopressured-geothermal resource development in coastal Louisiana  

Science Conference Proceedings (OSTI)

Gulf Coast high temperature (> 275 F) geopressured brines are more or less saturated with dissolved natural gas. These can be exploited at high flow rated (> 20,000 barrels per day) using wells completed with modified conventional technology for extracting gas from brine. Surface subsidence, fault reactivation, induced subsurface faulting and fracturing, brine spills, wetland loss, and the contamination of fresh water aquifers are the major potential hazards involved in this resource development which were all taken into consideration for implementing the environmental monitoring program being currently carried out at the well test sites. High volume production from a geopressured reservoir causes depressurization, compaction, and dewatering which could translate into surface subsidence rates that are greater than base line rates unless pressure is maintained by water ingress at the boundaries of producing reservoirs. Subsidence is of critical concern in coastal Louisiana where much of the land surface is at or below sea level. Increased subsidence will result in urban flooding, wetland loss, and loss of ecosystem habitats. Induced stresses could result in new faulting and fracturing enabling fluid flow between previously unconnected reservoirs and possibly contaminating fresh water aquifers. Fault displacements and minor earth movements can be detected with microseismic monitoring which is being done. Brine spills at well sites which could not be contained within levees will seriously impact the surrounding marshes and some minor wetland loss may occur in establishing production sites. Continued no major environmental impact attributable to resource testing.

The Geopressured-Geothermal Program: Energy conversion status and future possibilities  

DOE Green Energy (OSTI)

The Geopressured-Geothermal Program, sponsored by the Department of Energy (DOE) began in 1976 with the Wells of Opportunity. This early research concentrated on resource characterization at several locations in Texas and Louisiana. More recently, the program has included well operations and supporting university research in geoscience and engineering. Long term flow testing, reinjection of brine, and scale prevention were accomplished at the Gladys McCall Well. The Pleasant Bayou Well provided additional data for modeling and predicting geopressured reservoir behavior. This year a hybrid power system (HPS) was constructed at Pleasant Bayou in cooperation with the Electric Power Research Institute (EPRI). This is the first conversion of the geopressured-geothermal resource to electricity. An economic review of geopressured-geothermal resource development concludes that using off-the-shelf technology, electricity can be produced for $0.125/kWh from a Gladys McCall type resource (40,000 bpd brine production, 27 scf methane/bbl, 288{degree}F brine, and 10-year resource life). The Pleasant Bayou type resource can produce electricity for $0.32/kWh. Advanced technology could reduce the cost to $0.16/kWh. A review and status of the HPS is presented with future possibilities for the program, including (1) recovery of medium and heavy oil with hot geopressured brine, (2) direct use, especially aquaculture, and (3) development and use of advanced technology for conversion at the Hulin Well, the deepest, hottest well in the program. The estimated improvement in efficiencies with advanced conversion technology range from 100 to 160%. This would greatly reduce the cost to produce electricity. 6 refs., 7 figs., 2 tabs.

Parcperdue Geopressure -- Geothermal Project: Appendix E  

DOE Green Energy (OSTI)

The mechanical and transport properties and characteristics of rock samples obtained from DOW-DOE L.R. SWEEZY NO. 1 TEST WELL at the Parcperdue Geopressure/Geothermal Site have been investigated in the laboratory. Elastic moduli, compressibility, uniaxial compaction coefficient, strength, creep parameters, permeability, acoustic velocities (all at reservoir conditions) and changes in these quantities induced by simulated reservoir production have been obtained from tests on several sandstone and shale samples from different depths. Most important results are that the compaction coefficients are approximately an order of magnitude lower than those generally accepted for the reservoir sand in the Gulf Coast area and that the creep behavior is significant. Geologic characterization includes lithological description, SEM micrographs and mercury intrusion tests to obtain pore distributions. Petrographic analysis shows that approximately half of the total sand interval has excellent reservoir potential and that most of the effective porosity in the Cib Jeff Sand is formed by secondary porosity development.

Geopressured geothermal bibliography. Volume II (geopressure thesaurus). Second Edition  

DOE Green Energy (OSTI)

This thesaurus of terminology associated with the geopressured geothermal energy field has been developed as a part of the Geopressured Geothermal Information System data base. It is a compilation of terms displaying synomymous, hierarchical, and other relationships between terms. These terms, which are called descriptors, constitute the special language of the information retrieval system - the system vocabulary. The function of this thesaurus is to provide a standardized vocabulary for the information storage and retrieval system to facilitate both the indexing and subject-searching processes. In indexing, a thesaurus is used to translate the natural language of the document to be indexed into the standardized system vocabulary and to place the document at the appropriate level of generality or specificity in relation to the other documents in the data base. In subject retrieval, the thesaurus is used to match the natural language used in search requests with the system vocabulary and to find the most appropriate term to represent a concept.

Technical support for geopressured-geothermal well activities in Louisiana  

DOE Green Energy (OSTI)

Continuous recording microearthquake monitoring networks have been established around US Department of Energy (DOE) geopressured-geothermal design wells in southwestern Louisiana and southeastern Texas since summer 1980 to assess the effects well development may have had on subsidence and growth-fault activation. This monitoring has shown several unusual characteristics of Gulf Coast seismic activity. The observed activity is classified into two dominant types, one with identifiable body phases (type 1) and the other with only surface-wave signatures (type 2). During this reporting period no type 1 or body-wave events were reported. A total of 230 type 2 or surface-wave events were recorded. Origins of the type 2 events are still not positively understood; however, little or no evidence is available to connect them with geopressured-geothermal well activity. We continue to suspect sonic booms from military aircraft or some other human-induced source. 37 refs., 16 figs., 6 tabs.

Economic review of the geopressured-geothermal resource with recommendations  

SciTech Connect

This report presents the results of an economic study conducted by the INEL under DOE Contract No. AC07-76ID01570 to evaluate the breakeven price to market energy from a geopressured-geothermal resource. A breakeven price is a minimum, per unit charge required for the developer to recover all direct and indirect costs and a rate of return sufficient to compensate the developer for depreciation, the time value of money, and the risk of failure. The DOE Geopressured-Geothermal Research Program and the DOE well testing and operations at three locations in the Gulf Coast region provide the bulk of resource and economic characteristics for this study. A menu-driven model was developed in LOTUS-123 to calculate the breakeven price to market gas and electricity from a geopressured-geothermal resource. This model was developed using the present value methodology and conservative assumptions. Assuming present well constraints and current off-the-shelf conversion technology, the breakeven price for electricity is about $0.26/kWh using only the thermal energy from a Hulin-type resource. Assuming identical resource and technology constraints, the breakeven price is reduced to about $0.15/kWh when using all available energy forms (methane, hydraulic, and thermal). Assuming the use of available advanced technologies, the breakeven price is reduced to about $0.10/kWh. Assuming the higher quality resource (with higher temperature and gas content) in the South Texas cases, the breakeven cost is about $0.095/kWh. Using advanced technology, this cost is further reduced to about $0.05/kWh. Both costs are within program goals. The results of this study suggest that the future direction of the Geopressured-Geothermal Program emphasize (a) selection of higher quality resource, (b) advanced energy conversion technology, and (c) total energy utilization.

The geopressured-geothermal resource: Transition to commercialization  

DOE Green Energy (OSTI)

The Geopressured-Geothermal resource has an estimated 5700 recoverable quad of gas and 11,000 recoverable quad of thermal energy in the onshore Texas and Louisiana Gulf Coast area alone. After 15 years the program is now beginning a transition to commercialization. The program presently has three geopressured-geothermal wells in Texas and Louisiana. The Pleasant Bayou Well has a 1 MWe hybrid power system converting some gas and the thermal energy to electricity. The Gladys McCall Well produced over 23 MM bbls brine with 23 scf per bbl over 4 1/2 years. It is now shut-in building up pressure. The deep Hulin Well has been cleaned out and short term flow tested. It is on standby awaiting funds for long-term flow testing. In January 1990 an Industrial Consortium for the Utilization of the Geopressured-Geothermal Resource was convened at Rice University, Houston, TX. Sixty-five participants heard industry cost-shared proposals for using the hot geopressured brine. Proposals ranged from thermal enhanced oil recovery to aquaculture, conversion, and environmental clean up processes. By the September meeting at UTA-Balcones Research Center, industry approved charters will have been received, an Advisory Board will be appointed, and election of officers from industry will be held. 11 refs., 8 figs., 1 tab.

Technology Transfer, Reaching the Market for Geopressured-Geothermal Resources  

DOE Green Energy (OSTI)

Technology transfer to the industrial sector for geopressured-geothermal technology has included diverse strategies, with successes and obstacles or roadblocks. Numerical data are tabulated in terms of response to the various strategies. Strategy categories include the following: feasibility studies and reports, consortium activities and proceedings, the Geothermal Resource Council, national and international meetings of the American Association of Petroleum Geologists, other societal and organizational meetings, and conferences, Department of Energy solicitation of interest in the Commerce Business Daily, industry peer review panels, and the Secretary's Technology Initiative. Additionally, the potential of a 12-page color brochure on the geopressured-geothermal resource, workshops, and cooperative research and development agreement (CRADA) is discussed. In conclusion, what is the best way to reach the market and what is the winning combination? All of the above strategies contribute to technology transfer and are needed in some combination for the desired success. The most successful strategy activities for bringing in the interest of the largest number of industries and the independents are the consortium meetings, one-on-one telephone calling, and consortium proceedings with information service followup. the most successful strategy activities for bringing in the interest and participation of ''majors'' are national and international peer reviewed papers at internationally recognized industry-related society meetings, and on-call presentations to specific companies. Why? Because quality is insured, major filtering has already taken place, and the integrity of the showcase is established. Thus, the focused strategy is reduced to a target of numbers (general public/minors/independents) versus quality (majors). The numerical results of the activities reflecting four years of technology transfer following the 15 year lead in the early phases of geopressured-geothermal program under the leadership of Dr. Myron Dorfman, reflect a dynamic surveying of what works in technology transfer with industry in the area of geopressured-geothermal resources. The identified obstacles can be removed and future efforts can benefit by this cataloging and discussion of results.

Recoverable Resource Estimate of Identified Onshore Geopressured Geothermal Energy in Texas and Louisiana (Presentation)  

Science Conference Proceedings (OSTI)

Geopressured geothermal reservoirs are characterized by high temperatures and high pressures with correspondingly large quantities of dissolved methane. Due to these characteristics, the reservoirs provide two sources of energy: chemical energy from the recovered methane, and thermal energy from the recovered fluid at temperatures high enough to operate a binary power plant for electricity production. Formations with the greatest potential for recoverable energy are located in the gulf coastal region of Texas and Louisiana where significantly overpressured and hot formations are abundant. This study estimates the total recoverable onshore geopressured geothermal resource for identified sites in Texas and Louisiana. In this study a geopressured geothermal resource is defined as a brine reservoir with fluid temperature greater than 212 degrees F and a pressure gradient greater than 0.7 psi/ft.

Geopressured-geothermal well activities in Louisiana. Annual report, 1 January 1991--31 December 1991  

DOE Green Energy (OSTI)

Since September 1978, microseismic networks have operated continuously around US Department of Energy (DOE) geopressured-geothermal well sites to monitor any microearthquake activity in the well vicinity. Microseismic monitoring is necessary before flow testing at a well site to establish the level of local background seismicity. Once flow testing has begun, well development may affect ground elevations and/or may activate growth faults, which are characteristic of the coastal region of southern Louisiana and southeastern Texas where these geopressured-geothermal wells are located. The microseismic networks are designed to detest small-scale local earthquakes indicative of such fault activation. Even after flow testing has ceased, monitoring continues to assess any microearthquake activity delayed by the time dependence of stress migration within the earth. Current monitoring shows no microseismicity in the geopressured-geothermal prospect areas before, during, or after flow testing.

Geopressured geothermal resource of the Texas and Louisiana Gulf Coast: a technology characterization and environmental assessment  

DOE Green Energy (OSTI)

Two aspects of the Texas and Louisiana Gulf Coast geopressured geothermal resource: (1) the technological requirements for well drilling, completion, and energy conversion, and, (2) the environmental impacts of resource exploitation are examined. The information comes from the literature on geopressured geothermal research and from interviews and discussions with experts. The technology characterization section emphasizes those areas in which uncertainty exists and in which further research and development is needed. The environmental assessment section discusses all anticipated environmental impacts and focuses on the two largest potential problems: (a) subsidence and (b) brine disposal.

Subsurface evaluation of the geopressured-geothermal Chloe Prospect, Calcasieu Parish, Louisiana  

DOE Green Energy (OSTI)

A 123 square mile area approximately 10 miles east of Lake Charles, Louisiana, has been studied to assess its potential geopressured-geothermal resources. Subsurface information was used to study the structure and stratigraphy of the area as they related to the development of geopressured aquifers. The Middle Frio Hackberry wedge was found to contain the geopressured-geothermal reservoir sand, as well as the shales responsible for the origin and sealing of the geopressured strata. The major reservoir within the wedge is the Hackberry massive A sand.

Future for geopressured-geothermal resources  

SciTech Connect

The geopressured-geothermal production technologies for recompleting the Hulin Well and design and operation of surface facilities appear to be well in hand. A preliminary capital cost estimate indicates $4.45 million is required to recomplete and prepare the Hulin Well for production testing. The planned recompletion of the production well, surface facilities, and disposal well will have the capability to handle 24,000 barrels per day (bpd) of brine. If the reservoir can produce this design flow of brine saturated with gas, and the gas can be sold for $1.30/thousand cubic feet (mcf), DOE should have a positive cash flow about $530 per day for the first year. If gas zones are located above the brine as indicated by logs, the positive cash flow could reach $4130 per day or higher. The principal uncertainties are the gas content of the brine and the reservoir performance, both initially and long term. A private developer would need a market price for natural gas of from $1.38 to $4.60 per mcf for a reasonable return on investment depending on the reservoir performance and whether or not zones of excess gas are actually encountered. 7 refs., 6 figs.

Analysis of electricity production costs from the geopressured geothermal resource  

SciTech Connect

The economics of the geopressured geothermal resource along the northern coast of the Gulf of Mexico is assessed. Geopressured waters are nearly under twice the normal hydrostatic pressure and believed to be saturated with methane. The costs of generating electricity from this resource are estimated based on the description and conceptual development plans provided by the United States Geological Survey (USGS). Methane content and selling prices are the most important factors affecting the commercial potential of geopressured resources--so it is important that electrical generation be viewed as a by-product of methane production. On the same incremental cost basis, the cost of electricity generated from the geohydraulic energy is potentially competitive with conventional energy sources. This would require development of a small commercial high pressure, hydraulic turbine to extract geohydraulic energy at the wellhead in plants of about 3 MW capacity. Price/quantity relationships are developed for electricity generation from geopressured resources for each of three development plans proposed by USGS. Studies, based on field constructed plants, indicated an optimum power plant size in the range of 20 to 60 MWe, depending on water temperature. However, if standardized thermal conversion power plants could be factory produced in the 6 MWe range competitively with larger field constructed plants, then the optimum plant size might be reduced to single wellhead units.Wellhead units would completely eliminate fluid transmission costs, but would probably incur higher costs for heat rejection, power plant operation, and electrical transmission. The upper cost target for competitive wellhead plants would be on the order of $800/kW in 1975 dollars.

The feasibility of hydraulic energy recovery from geopressured- geothermal resources  

DOE Green Energy (OSTI)

This report presents the results of a study conducted by the Idaho National Engineering Laboratory (INEL) for DOE on the application of hydraulic energy recovery from geopressured-geothermal resources. The report examines both the technical and economic feasibility. Previous reports and demonstrations of geopressured-geothermal energy have been directed to the recovery of heat and methane. This report is specifically directed to extracting the pressure component of a typical reservoir. The pressure energy available in a 220 psia geopressured fluid could yield 1.49 W{center dot}h per pound and an average well could produce 500kW. The best available device for recovering this energy is a Pelton turbine. Commercial Pelton turbines are not available for this application but are technically feasible. Suitable turbines could be developed with first of a kind engineering and tooling costs of approximately $227,000. The breakeven cost to add conversion of hydraulic energy to an existing methane/heat recovery system would be $0.030 per kWh based on a 10 year lifetime. Development testing is necessary to understand the effect of the dissolved gases, verify cavitation suppression, and materials selection. Cavitation suppression would be provided by utilizing the gas backpressure of the dissolved methane and carbon dioxide that exists in the geofluid. It is estimated that adding conversion of hydraulic energy to an operating system recovering heat and methane could reduce the overall cost of electrical production by about 1.5 cents per kWh. This is not a viable stand-alone system is the well costs are to be born by the conversion of hydraulic energy alone. 5 refs., 4 figs., 2 tabs.

Fiscal Year 1992 Annual Operating Plan for the Geopressured-Geothermal Research Program ($4.3 Million Budget)  

Science Conference Proceedings (OSTI)

This plan describes the Geopressured-Geothermal Research Program. A Geopressured well in Texas (Pleasant Bayou) will undergo a slow test and a pressure buildup test. A geopressured well in Louisiana (Gladys McCall) will be flow tested for a short period, logged, plugged and abandoned or turned over to industry early in FY 92. A second deep geopressured well in Louisiana, the Hulin Well, is being kept on standby. Related university research in geology, numerical reservoir modeling, subsidence, microseismicity, and water quality will continue, with program data reviews initiated in appropriate areas. Increased emphasis on integrated reservoir engineering will be implemented. The well activities coupled with the related university research are designed to improve the ability to forecast reservoir productive capacity, to verify the reliability of the resource as a long-term energy resource, and to determine the environmental effects of long-term production. By these means, the Geopressured-Geothermal Research Program is developing a solid technology base that private industry can use to evaluate the geopressured-geothermal resource. The Industrial Consortium for utilization of the resource will be continued. Use projects in Louisiana and Texas will be evaluated. A geopressured reservoir review will be managed by INEL. The DOE Field Office, Idaho will make preparations to complete the program. [DJE-2005

US Gulf Coast geopressured-geothermal reservoir simulation. Final report (Year 3)  

DOE Green Energy (OSTI)

Several reservoir model improvements incorporated into the UTA model are described. The most significant modification to the model was the inclusion of semiimplicit treatment of transmissibilities so as to better handle two-phase flow problems associated with flow near the wellbore. A description of the reservoir mechanics presumed operative in geopressured-geothermal reservoirs is included. A mathematical model describing two-dimensional flow in compacting porous media is developed from the Lagrangian point of view. A description of the way the differential equations are approximated by finite differences and subsequently solved by means of numerical procedures is presented. Various sensitivity studies made with the reservoir model are described. Particular emphasis was given to the study of potential shale dewatering effects on reservoir depletion and the effects of compaction on fluid recovery. To study shale dewatering, the shale thickness and the shale vertical permeability were treated as variables in several simulation experiments. The effects of compaction were modeled with optimistic and pessimistic values for the uniaxial compaction coefficient in an attempt to define a region of expected reservoir performance. Laboratory analysis of core samples obtained from the geopressured-geothermal test well was completed by the end of year 3. These data indicate that the uniaxial compaction coefficient is of the same order of magnitude as the pessimistic value used on the sensitivity studies. Because of this the expected fluid recovery from geopressured reservoirs has been reduced to a nominal 5% of the in-place volumes rather than the previously reported 10%.

Operations research and systems analysis of geopressured-geothermal energy in Louisiana. Final report for the period June 1, 1978-August 31, 1979  

DOE Green Energy (OSTI)

The primary purpose was to provide a projection of the probable future contribution of the geopressured-geothermal energy resource in Louisiana to the overall energy requirements of the nation. A number of associated objectives were emphasized: namely, development of the tools and methodology for performing economic analyses, application of these tools to specific prospects about which adequate resource assessments have been made, identification of the impediments to resource development, and socio-economic analysis of the impact of development of the resource on these specific prospects. An overview of the geopressured-geothermal resource activities in Louisiana is provided first, followed by a detailed discussion and review of the achievements of this project. Finally the major conclusions and findings of this project with respect to commercial viability, impediments, and social and economic impact are presented, and recommendations are made for future systems analysis work.

Testing geopressured geothermal reservoirs in existing wells: Detailed completions prognosis for geopressured-geothermal well of opportunity, prospect #1  

SciTech Connect

This prospective well of opportunity was originally drilled and completed as a gas producer by Wrightsman Investment Company in early 1973. The original and present producing interval was from 15,216 to 15,238 feet. IMC Exploration Company, Inc. acquired the property from Wrightsman and is the present owner operator. The well is presently shut in s a non-economic producer and IMC proposed to perform plug and abandonment operations in April, 1980. This well has a good geopressured-geothermal water sand behind the 5-1/2 inch casing that has 94 feet of net sand thickness. Pursuant to DOE/NVO authorization of March 11,1980, Eaton negotiated an option agreement with IMC whereby IMC would delay their abandonment operations for a period of 90 days to permit DOE to evaluate the well for geopressure-geothermal testing. The IMC-Eaton option agreements provide that IMG will delay plugging the well until June 15, 1980. If Eaton exercises its option to acquire the well, IMC will sell the well bore, and an adjacent salt water disposal well, to Eaton for the sole consideration of Eaton assuming the obligation to plug and abandon the wells in accordance with lease and regulatory requirements. If Eaton does not exercise its option, then Eaton will pay IMC $95,000 cash and IMC will proceed with plugging and abandonment at the termination of the option period.

Methane extraction from geopressured-geothermal brine at wellhead conditions  

DOE Green Energy (OSTI)

Disposal of geopressured-geothermal brine effluents by injection is expected to be costly, even into shallow aquifers. If injection into the production reservoir becomes necessary to maintain productivity and to minimize subsidence, the injection pumping costs can become overwhelming. An option aimed at reducing injection pump operating costs is to maintain a higher than normal pressure at the production wellhead to reduce the injection pumping load. The crucial element, however, is that a significant portion of CH/sub 4/ remains in solution and must be recovered in order for the pressure maintenance option to be cost effective. A laboratory and field test capability has been established, and several methods for extracting dissolved CH/sub 4/ at high temperature and pressure are being evaluated. Solvent extraction and use of hydraulic motors or turbines coupled to CH/sub 4/ recovery systems are the leading candidate methods.

Survey of California Geopressured-Geothermal Potential  

SciTech Connect

Geopressured reservoirs contain three types of energy: thermal, hydraulic, and methane gas. The thermal energy generally is a function of depth of burial. It can be converted to electricity using the binary or flash power plant cycle, the flash technology being commercial only if the fluid temperature exceeds about 340 F. The hydraulic energy can be converted to electrical power using a hydraulic turbine. The dissolved gas can be separated and either used to produce electricity using a gas turbine or sold commercially. These reservoirs occur in many states in the USA, including California. An overburden pressure is caused by the combined weight of the formation rock and the fluids (water/gas/oil) present in the pore spaces overlying the formation of interest. The overburden pressure, in general, increases relatively uniformly with depth, whereas the hydrostatic gradient is mainly a function of two variables: the dissolved solids concentration and the temperature gradient. The hydrostatic pressure gradient for fresh water is 0.433 psi/ft. Geopressured reservoirs are overpressured; that is, the fluid pressure in the reservoir exceeds the pressure corresponding to the local hydrostatic pressure gradient. (Fig. 3) Confining bed or cap rock is necessary in order for a formation to be geopressured. Otherwise, the pressure would equalize to hydrostatic through upward flow. The pressures in a geopressured reservoir may approach the overburden pressure of about 1 psi/ft. Gulf Coast geopressured reservoirs typically exist between 12,000 to 20,000 feet below the surface. Flow rates of between 10,000 to 40,000 barrels per day, temperatures from 270 to 500 F, bottom hole pressures from 12,000 to 18,500 pounds psi, salinities of 20,000 to 200,000 milligrams per liter, and gas contents of 23 to 100 standard cubic feet per barrel, have been reported from geopressured wells.

Operations research and systems analysis of geopressured/geothermal resources in Texas. Final report  

DOE Green Energy (OSTI)

A preliminary resource assessment, based on the best available parameters, was made to identify potentially suitable fairways. Of those examined only the Brazoria Fairway in the Frio Formation was able to produce sufficient fluid to meet the minimum requirements. These requirements are based upon the need for a well to produce an initial flow rate of 40,000 bbl/day with a 6% decline rate over a 30 year production period. Next, a development planning analysis was done to determine the number of wells that would have to be drilled in the fairway, considering the probability of success, and the number of drilling rigs available. The results of this analysis provided a time phased scenario and costs of developing the fairway. These were next used in an economic analysis. The economic analysis was performed to determine the present worth of using the resource under a range of values for the key economic parameters. The results of this study indicate that the commercial development of geopressured, geothermal resource is highly dependent upon the pricing of natural gas in the US, the development of tax incentives to spur development, and a better understanding of the nature of the resource through additional well tests.

Consolidation of geologic studies of geopressured geothermal resources in Texas. 1982 annual report  

DOE Green Energy (OSTI)

Detailed structural mapping at several horizons in selected study areas within the Frio growth-fault trend demonstrates a pronounced variability in structural style. At Sarita in South Texas, shale mobilization produced one or more shale ridges, one of which localized a low-angle growth fault trapping a wedge of deltaic sediments. At Corpus Christi, shale mobilization produced a series of large growth faults, shale-cored domed anticlines, and shale-withdrawal basins, which become progressively younger basinward. At Blessing, major growth faults trapped sands of the Greta/Carancahua barrier system with little progradation. At Pleasant Bayou, a major early growth-fault pattern was overprinted by later salt tectonics - the intrusion of Danbury Dome and the development of a salt-withdrawal basin. At Port Arthur, low-displacement, long-lived faults formed on a sand-poor shelf margin contemporaneously with broad salt uplifts and basins. Variability in styles is related to the nature and extent of Frio sedimentation and shelf-margin progradation and to the presence or absence of salt. Structural styles that are conducive to the development of large geothermal reservoirs include blocks between widely spaced growth faults having dip reversal, salt-withdrawal basins, and shale-withdrawal basins. These styles are widespread on the Texas Gulf Coast. However, actually finding a large reservoir depends on demonstrating the existence of sufficient sandstone with adequate quality to support geopressured geothermal energy production.

Structural evolution of three geopressured-geothermal areas in the Texas Gulf Coast  

DOE Green Energy (OSTI)

Detailed analysis of geological and seismic data from several geopressured geothermal areas (Cuero, Blessing, Pleasant Bayou) reveals similarities in structural-stratigraphic relationships that form geopressured aquifers as well as differences in structural complexity and evolution that characterize the different areas. In these examples, geopressured sandstones are isolated on the updip side by downfaulting against shelf-slope shales, and on the downdip side by upfaulting against transgressive marine shales. Moreover, they are isolated above and below by thick sequences of transgressive shale or interbedded sandstone and shale. Prospective reservoirs are found where delatic and associated sandstones (distributary channel, delta front, barrie-strandplain) were deposited seaward of major growth faults and near the shelf margin. Structural development in these areas began with rapid movement of relatively straight to sinuous down-to-the basin growth faults with narrow to wide spacings and varying amounts of rollover. Later structural movement was characterized by continued but slower movement of most growth faults. In the Pleasant Bayou area, late salt diapirism superimposed a dome-and-withdrawal-basin pattern on the earlier growth-fault style.

Testing geopressured geothermal reservoirs in existing wells: Detailed completion prognosis for geopressured-geothermal well of opportunity, prospect #2  

DOE Green Energy (OSTI)

A geopressured-geothermal test of Martin Exploration Company's Crown Zellerbach Well No. 2 will be conducted in the Tuscaloosa Trend. The Crown Zellerbach Well No. 1 will be converted to a saltwater disposal well for disposal of produced brine. The well is located in the Satsuma Area, Livingston parish, Louisiana. Eaton proposes to test the Tuscaloosa by perforating the 7 inch casing from 16,718 feet to 16,754 feet. The reservoir pressure at an intermediate formation depth of 16,736 feet is anticipated to be 12,010 psi and the temperature is anticipated to be 297 F. Calculated water salinity is 16,000 ppm. The well is expected to produce a maximum of 16,000 barrels of water a day with a gas content of 51 SCF/bbl. Eaton will re-enter the test well, clean out to 17,000 feet, run production casing and complete the well. The disposal well will be re-entered and completed in the 9-5/8 inch casing for disposal of produced brine. Testing will be conducted similar to previous Eaton annular flow WOO tests. An optional test from 16,462 feet to 16,490 feet may be performed after the original test and will require a workover with a rig on location to perform the plugback. The surface production equipment utilized on previous tests will be utilized on this test. The equipment has worked satisfactorily and all parties involved in the testing are familiar with its operation. Weatherly Engineering will operate the test equipment. The Institute of Gas Technology (IGT) and Mr. Don Clark will handle sampling, testing and reservoir engineering evaluation, respectively. wireline work required will be awarded on basis of bid evaluation. At the conclusion of the test period, the D.O.E. owned test equipment will be removed from the test site, the test and disposal wells plugged and abandoned and the sites restored to the satisfaction of all parties.

Subsurface and seismic investigation of the geopressured-geothermal potential of south Louisiana. Final report  

DOE Green Energy (OSTI)

Specific sites (areas) for geopressured-geothermal energy potential have been evaluated: (1) Abbeville Area, (2) Chloe Area, (3) Turtle Bayou Field-Kent Bayou Field Area and (4) Lirette-Chauvin-Lake Boudreaux Area. To arrive at geologic conclusions concerning the geopressured-geothermal energy potential of each area, the following factors have been considered in this study: (1) depth of geopressured sands, (2) geopressured sand volumes, (3) porosities, (4) permeabilities, (5) temperatures, (6) salinities, (7) dissolved gas content, (8) structure - especially as it relates to continuity of reservoirs, and (9) petroleum prodution - espeially if the geopressured fluids are driving mechanisms for current petroleum prodution. To evaluate these parameters the most useful source of information has been petroleum well logs which most commonly are a continuous depth survey of the spontaneous potential (SP) and the electrical resistivity of the subsurface formations. A separate thesis for each of the above four areas was processed separately.

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.

Session 12: Land Subsidence and Microseismicity Associated with Geopressured-Geothermal Fluid Production  

DOE Green Energy (OSTI)

Subsidence and fault-related surface displacements are the chief environmental concerns related to the long-term production of large volumes of fluids from geopressured-geothermal reservoirs. Environmental monitoring efforts at the three designed test well sites in Louisiana (Parcperdue, Sweet Lake, and Gladys McCall) have focused on leveling surveys, recording of microseismic events, and tiltmeter installation to provide baseline and fluid-production-related data useful in measuring land-surface and faulting effects of testing. Analysis of pretesting land-surface elevation surveys has revealed a complex pattern of subsidence related to sediment compaction, basin subsidence, and possibly to ground-water production and soil wetting and drying. The relative importance of each of these is not clear and the impact of geopressured-geothermal fluid production has not been determined. A three-year period of microseismic monitoring has produced reports by contractors of some 1000 suspected microseismic events; many of these require further verification. 64 events were recorded at Parcperdue, 141 at Gladys McCall, and 893 at Sweet Lake. Considering only events recorded by 5 stations or more reduces the total to 316, of which only six have the classic microseismic event characteristics. Analysis of all recorded events and their relation to fluid production and/or disposal is continuing. Tiltmeter data from Sweet Lake indicate that ground deformation correlates with fluid production and seismicity. This relationship is being studied and will be compared with data from Gladys McCall gathered during fluid production. The complexity of background subsidence and fault-related processes in the Gulf Coast area makes identification of processes directly related to geopressured-geothermal fluid production very difficult. Data from Sweet Lake suggest a correlation; hopefully, results from Gladys McCall will clarify interpretations made thus far.

The feasibility of recovering medium to heavy oil using geopressured- geothermal fluids  

DOE Green Energy (OSTI)

The feasibility, economics and environmental concerns of producing more domestic oil using thermal enhanced oil recovery (TEOR) are reviewed and the unique nature of geopressured-geothermal (GPGT) fluids for thermal recovery are outlined. Current methods of TEOR are briefly discussed and it is noted that these methods are presently under scrutiny by both federal and state air quality agencies; and moreover, they often involve costly operational and mechanical problems associated with heating water on the surface for injection into the target reservoir. The characteristics of the GPGT resources as seen through previous Department of Energy (DOE) studies from sites in Louisiana and Texas are discussed. These studies indicate sufficient quantities of GPGT fluids can be produced to sustain a TEOR project. The Alworth Field in the south Texas Mirando Trend is proposed as a TEOR pilot site. The target reservoirs for injection of the GPGT fluids are the Jackson and Yegua sandstones of the upper Eocene Epoch. The reservoirs contain an estimated 4 MMbbls of heavy oil in place (OIP) (18.6{degree}API) of which it is estimated that at least 1 MMbbls could be recovered by TEOR. The problems associated with using the GPGT fluids for TEOR include those normally associated with hot water flooding but in addition the reaction of the brine from the geopressured-geothermal reservoir with the target reservoir is uncertain. Under the elevated temperatures associated with GPGT TEOR, actual increased porosity and permeability are possible. 120 refs., 40 figs., 13 tabs.

Depletion and recovery behavior of the Gladys McCall geopressured geothermal reservoir  

DOE Green Energy (OSTI)

Many sedimentary basins throughout the world contain sealed fault blocks in which the pore fluids are at higher pressures and temperatures than normal as a consequence of their depositional environment. The U.S. Department of Energy has drilled, completed, and tested four deep research wells in selected geopressured geothermal prospects in the Texas-Louisiana Gulf Coast region to evaluate the recoverability of the thermal, hydraulic, and chemical (methane) energy in this potential energy resource. The wells are expensive and the specific energy of the fluids is relatively small, but the total recoverable energy from a single well can be extremely large. Long-term testing of the Gladys McCall No. 1 research well, located in Cameron Parish, Louisiana, U.S.A., has defined an impressively large geopressured geothermal reservoir. In this paper an integrated analysis of the test data is presented, and a numerical model is constructed that matches the available data for the 6.5-year test history of the well.

In 1990, research at the Bureau of Economic Geology concentrated on evaluating the potential of using geopressured-geothermal water for hot-water flooding of heavy-oil reservoirs. Favorable geothermal reservoirs are defined by thick deltaic sandstones and growth-fault-bounded compartments. Potential geothermal reservoirs are present at a depth of 11,000 ft (3,350 m) to 15,000 ft (4,570 m) and contain water at temperatures of 350 F (177 C) to 383 F (195 C) in Fandango field, Zapata County. One potential geothermal reservoir sandstone in the upper Wilcox (R sandstone) is composed of a continuous sand body 100 ft (30 m) to greater than 200 ft (>61 m) thick. Fault blocks average 2 to 4 mi{sup 2} (5.2 to 10.4 km{sup 2}) in area.

Geopressured Geothermal Resource and Recoverable Energy Estimate for the Wilcox and Frio Formations, Texas (Presentation)  

DOE Green Energy (OSTI)

An estimate of the total and recoverable geopressured geothermal resource of the fairways in the Wilcox and Frio formations is made using the current data available. The flow rate of water and methane for wells located in the geopressured geothermal fairways is simulated over a 20-year period utilizing the TOUGH2 Reservoir Simulator and research data. The model incorporates relative permeability, capillary pressure, rock compressibility, and leakage from the bounding shale layers. The simulations show that permeability, porosity, pressure, sandstone thickness, well spacing, and gas saturation in the sandstone have a significant impact on the percent of energy recovered. The results also predict lower average well production flow rates and a significantly higher production of natural gas relative to water than in previous studies done from 1975 to 1980. Previous studies underestimate the amount of methane produced with hot brine. Based on the work completed in this study, multiphase flow processes and reservoir boundary conditions greatly influence the total quantity of the fluid produced as well as the ratio of gas and water in the produced fluid.

Pleasant Bayou geopressured/geothermal testing project, Brazoria County, Texas. Final report  

DOE Green Energy (OSTI)

Phase II-B production testing of the Pleasant Bayou No. 2 well began September 22, 1982. The test plan was designed to evaluate the capabilities of the geopressured-geothermal reservoir during an extended flow period. Tests were conducted to determine reservoir areal extent; aquifer fluid properties; fluid property change with production; information on reservoir production drive mechanism; long-term scale and corrosion control methods; and disposal well operations. Operatinal aspects of geopressured-geothermal production were also evaluated. The test was discontinued prematurely in May 1983 because of a production tubing failure. Most of the production tubing was recovered from the well and cause of the failure was determined. Plans for recompletion of the well were prepared. However, the well was not recompleted because of funding constraints and/or program rescheduling. In March 1984, the Department of Energy, Nevada Operations Office (DOE/NV) directed that the site be placed in a standby-secured condition. In August 1984, the site was secured. Routine site maintenance and security was provided during the secured period.

Consolidated Research Program United States Gulf Coast Geopressured-Geothermal Program  

DOE Green Energy (OSTI)

The logging research program in the DOE Geopressured-Geothermal Energy Project was set up to (a) carry out research on logging problems important to the DOE program; (b) provide advice on logging programs in DOE wells; (c) monitor log quality during data acquisition; (d) provide log analyses as requested by DOE and (e) provide other services as skills and time permit. Funding for the project amounted to about $50,000/year from 1979 to 1985 (direct cost plus overhead). In 1986 DOE funding began to increase and was about $100,000 per year for the last three years of the project (1988-91). In addition to DOE funding, the Gas Research Institute Tight Gas Sands Project contributed to our boron research by about $7,000 per year during 1989-91, plus about $100,000 worth of core and log data from five tight gas sand wells in East and West Texas and in Wyoming.

Preliminary conceptual design of commercial geopressured geothermal fuel plants  

SciTech Connect

Previous feasibility studies Bechtel (1975), TRW (1975) for electric power generation utilizing geothermal resources have tended to focus primarily on the power plant and have neglected the fuel production and effluent disposal facilities. The Dow Chemical USA study (1974) for the Governor's Energy Advisory Council, State of Texas, placed equal emphasis on the power plant and the fuel plant. The study reported in Chapter II and in what follows in this chapter, also places equal emphasis on the two types of facilities. It is important that the fuel plant, the well field, the fuel processing plant, and the effluent disposal facility be the subject of a preliminary conceptual design and costing activity so that economic and net energetics analysis can be performed. The activity also serves to assess technological maturity of the fuel plant and to identify technical problems requiring further study. The resource considered was the model resource outlined in Sectio B, Chapter II. Fuel plants were outlined for three power generation plants: single-stage flash steam, two-stage flash steam, and propane secondary working fluid plant.

T-F and S/DOE Gladys McCall No. 1 well, Cameron Parish, Louisiana. Geopressured-geothermal well report, Volume II. Well workover and production testing, February 1982-October 1985. Final report. Part 1  

DOE Green Energy (OSTI)

The T-F and S/DOE Gladys McCall No. 1 well was the fourth in a series of wells in the DOE Design Wells Program that were drilled into deep, large geopressured-geothermal brine aquifers in order to provide basic data with which to determine the technological and economic viability of producing energy from these unconventional resources. This brine production well was spudded on May 27, 1981 and drilling operations were completed on November 2, 1981 after using 160 days of rig time. The well was drilled to a total depth of 16,510 feet. The target sands lie at a depth of 14,412 to 15,860 feet in the Fleming Formation of the lower Miocene. This report covers well production testing operations and necessary well workover operations during the February 1982 to October 1985 period. The primary goals of the well testing program were: (1) to determine reservoir size, shape, volume, drive mechanisms, and other reservoir parameters, (2) to determine and demonstrate the technological and economic viability of producing energy from a geopressured-geothermal brine aquifer through long-term production testing, and (3) to determine problem areas associated with such long-term production, and to develop solutions therefor.

Methods for collection and analysis of geopressured geothermal and oil field waters  

DOE Green Energy (OSTI)

Present methods are described for the collection, preservation, and chemical analysis of waters produced from geopressured geothermal and petroleum wells. Detailed procedures for collection include precautions and equipment necessary to ensure that the sample is representative of the water produced. Procedures for sample preservation include filtration, acidification, dilution for silica, methyl isobutyl ketone (MIBK) extraction of aluminum, addition of potassium permanganate to preserve mercury, and precipitation of carbonate species as strontium carbonate for stable carbon isotopes and total dissolved carbonate analysis. Characteristics determined at the well site are sulfide, pH, ammonia, and conductivity. Laboratory procedures are given for the analysis of lithium, sodium, potassium, rubidium, cesium, magnesium, calcium, strontium, barium, iron, manganese, zinc, lead, aluminum, and mercury by atomic absorption and flame emission spectroscopy. Chloride is determined by silver nitrate titration and fluoride by ion-specific electrode. Bromide and iodide concentrations are determined by the hypochlorite oxidation method. Sulfate is analyzed by titration using barium chloride with thorin indicator after pretreatment with alumina. Boron and silica are determined colorimetrically by the carmine and molybdate-blue methods, respectively. Aliphatic acid anions (C/sub 2/ through C/sub 5/) are determined by gas chromatography after separation and concentration in a chloroform-butanol mixture.

Factors controlling reservoir quality in tertiary sandstones and their significance to geopressured geothermal production  

DOE Green Energy (OSTI)

Variable intensity of diagenesis is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the upper and lower Texas coast. Detailed comparison of Frio sandstone from the Chocolate Bayou/Danbury Dome area, Brazoria County, and Vicksburg sandstones from the McAllen Ranch Field area, Hidalgo County, reveals that extent of diagenetic modification is most strongly influenced by (1) detrital mineralogy and (2) regional geothermal gradients. The regional reservoir quality of Frio sandstones from Brazoria County is far better than that characterizing Vicksburg sandstones from Hidalgo County, especially at depths suitable for geopressured geothermal energy production. However, in predicting reservoir quality on a site-specific basis, locally variable factors such as relative proportions for porosity types, pore geometry as related to permeability, and local depositional environment must also be considered. Even in an area of regionally favorable reservoir quality, such local factors can significantly affect reservoir quality and, hence, the geothermal production potential of a specific sandstone unit.

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.

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.

Technical support for geopressured-geothermal well activities in Louisiana; Final report, 1 January 1992--31 December 1993  

DOE Green Energy (OSTI)

The US Department of Energy has operated continuous-recording, microearthquake monitoring networks at geopressured-geothermal test well sites since 1980. These microseismic networks were designed to detect microearthquakes indicative of fault activation and/or subsidence that can potentially result from the deep subsurface withdrawal and underground disposal of large volumes of brine during well testing. Seismic networks were established before the beginning of testing to obtain background levels of seismicity. Monitoring continued during testing and for some time after cessation of flow testing to assess any delayed microseismicity caused by the time dependence of stress migration within the earth. No flow testing has been done at the Hulin well since January 1990, and the Pleasant Bayou well has been shut down since September 1992. Microseismic monitoring continued at the Hulin and Pleasant Bayou sites until 31 December 1992, at which time both operations were shut down and field sites dismantled. During 1992, the networks recorded seismic signals from earthquakes, sonic booms, geophysical blasting, thunderstorms, etc. However, as in previous years, no local microseismic activity attributable to geopressured-geothermal well testing was recorded.

Testing geopressured geothermal reservoirs in existing wells. Wells of Opportunity Program final contract report, 1980-1981  

DOE Green Energy (OSTI)

The geopressured-geothermal candidates for the Wells of Opportunity program were located by the screening of published information on oil industry activity and through direct contact with the oil and gas operators. This process resulted in the recommendation to the DOE of 33 candidate wells for the program. Seven of the 33 recommended wells were accepted for testing. Of these seven wells, six were actually tested. The first well, the No. 1 Kennedy, was acquired but not tested. The seventh well, the No. 1 Godchaux, was abandoned due to mechanical problems during re-entry. The well search activities, which culminated in the acceptance by the DOE of 7 recommended wells, were substantial. A total of 90,270 well reports were reviewed, leading to 1990 wells selected for thorough geological analysis. All of the reservoirs tested in this program have been restricted by one or more faults or permeability barriers. A comprehensive discussion of test results is presented.

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)

Feasibility study: Application of the geopressured-geothermal resource to pyrolytic conversion or decomposition/detoxification processes  

DOE Green Energy (OSTI)

This study presents a preliminary evaluation of the technical and economic feasibility of selected conceptual processes for pyrolytic conversion of organic feedstocks or the decomposition/detoxification of hazardous wastes by coupling the process to the geopressured-geothermal resource. The report presents a detailed discussion of the resource and of each process selected for evaluation including the technical evaluation of each. A separate section presents the economic methodology used and the evaluation of the technically viable process. A final section presents conclusions and recommendations. Three separate processes were selected for evaluation. These are pyrolytic conversion of biomass to petroleum like fluids, wet air oxidation (WAO) at subcritical conditions for destruction of hazardous waste, and supercritical water oxidation (SCWO) also for the destruction of hazardous waste. The scientific feasibility of all three processes has been previously established by various bench-scale and pilot-scale studies. For a variety of reasons detailed in the report the SCWO process is the only one deemed to be technically feasible, although the effects of the high solids content of the geothermal brine need further study. This technology shows tremendous promise for contributing to solving the nation's energy and hazardous waste problems. However, the current economic analysis suggests that it is uneconomical at this time. 50 refs., 5 figs., 7 tabs.

Preliminary test results and geology of the DOE/Superior Hulin. number sign. 1 geopressured-geothermal well, Vermillion Parish, Louisiana  

Science Conference Proceedings (OSTI)

The DOE/Superior Hulin {number sign}1 well is the most recent of the current three geopressured-geothermal prospects being tested by the Department of Energy (DOE) under its geopressured-geothermal program initiated in 1975. The other prospects under evaluation are Gladys McCall {number sign}1 (Cameron Parish, LA) and Pleasant Bayou {number sign}2 (Brazoria County, TX). The main objective of this research program is to evaluate the commercial viability of energy production from high temperature (275{degrees}+F.), geopressured, natural-gas-saturated brine sandstone aquifers occur-ring in the Gulf Coast area. The DOE/Superior Hulin {number sign}1 well is located 7.5 mi (12 km) south of the town of Erath, Louisiana. It was originally drilled and later sidetracked as an exploration well by Superior Oil Company to a depth of 21,549 ft (6,568 m) and completed in 1979. The well produced 0.3 bcf gas in 19 months from the interval between 21,059 and 21,094 ft (6,419-6,429 m). Later, owing to production problems caused by tubing/casing failure, Superior abandoned production and transferred the well to DOE for testing under the geopressured-geothermal program. The well has recently been cleaned and recompleted by Eaton Operating Company, Houston, Texas, and plugged back to 20,725 ft (6,317 m). This well penetrates the deepest known Gulf Coast geopressured-geothermal reservoir and has a maximum recorded temperature of 338{degrees}F with a 560 ft (171 m) thick sandstone. Regional geologic work indicates that the Hulin sandstone represents either a submarine canyon or an unstable shelf delta type of environment. The well is presently perforated at the bottom of the sandstone from 20,610 to 20,690 ft (6282-6306 m) for preliminary short-term testing now in progress. Initial testing indicates the gas-brine ratio to be 31 SCF/STB.

The well provided the second geopressured-geothermal test to be completed under the DOE-Gruy Well of Opportunity program. The completion in a geopressured aquifer of Oligocene age at approximately 14,700 feet and the testing of hot salt water from this zone were accomplished without significant difficulty. Some problems were encountered with the wireline and wireline high-pressure lubricator associated with the running of bottomhole instruments. The objectives of the project were all accomplished, and good test data were obtained on the flow rates of gas and water. The gas content was 24 standard cubic feet per stock tank barrel of water. The disposal well accepted the full wellhead stream at temperatures as high as 255{sup 0}F (124{sup 0}C). Over the 10-day flow period the hot brine did not appear to adversely affect the clay minerals in the disposal aquifer. A conclusion from this operation is that presently available wirelines and pressure lubricators are not adaptable for use with uninhibited well fluids under flowing conditions. In addition, this test demonstrated that injection of scale inhibitor down the annulus eliminated scale buildup within the flow string and surface facilities. (MHR)

Investigation and evaluation of geopressured-geothermal wells. Fairfax Foster Sutter No. 2 well, St. Mary Parish, Louisiana. Volume I. Completion and testing. Final report  

DOE Green Energy (OSTI)

The Fairfax Foster Sutter No. 2 well, located in the East Franklin area of St. Mary Parish, Louisiana, is the first successful test of a geopressured-geothermal aquifer under the Well-of-Opportunity program. The section tested was the MA-6 sand of lower Miocene age which has produced large quantities of gas from the adjacent but structurally separated Garden City field. In the subject well the observed temperature was 270{sup 0}F (132{sup 0}C) and the measured gradient was 0.77 psi/ft. The gross sand thickness was 270 feet, the net sand thickness 190 feet, and the tested interval 58 net feet. The temperatures and pressures encountered approached the limits of the surface-recording bottomhole pressure gauge and particularly the single-conductor cables on which the gauges were run. The objectives of the tests were all accomplished, and data were obtained which will contribute to the overall assessment of the geopressured-geothermal resource of the Upper Gulf of Mexico basin. In general, the gas solubility (22.8 scf/bbl) was as expected for the temperature, pressure, and salinity of the brine. The produced water was more saline than expected (160,000 mg/l). The high concentrations of dissolved solids, coupled with the evolution of CO{sub 2} from these waters during production, created a scaling problem in the tubular goods and surface equipment that will have to be addressed in future tests.

Investigation and Evaluation of Geopressured - Geothermal Wells, Final Report; Alice C. Plantation No. 2 Well, St. Mary Parish, Louisiana; Volume 1; Narrative Report  

DOE Green Energy (OSTI)

Gruy Federal, Inc. (Gruy) operates under Contract No. EG-77-C-08-1528 to the Department of Energy, Division of Geothermal Energy, to evaluate potential alternate energy sources occurring within geopressured-geothermal (Geo) aquifers in Miocene, Oligocene, Tuscaloosa, Wilcox, and Frio formations along the Texas and Louisiana Gulf Coast. The project is entitled ''Investigation and Evaluation of Geopressured-Geothermal Wells''. The original period of performance was from September 26, 1977, through September 30, 1978; the contract was later extended through September 30, 1979. The first well on which testing was attempted under this contract was the Alice C. Plantation No. 2 Well, located in St. Mary Parish, Louisiana. Originally drilled by the Sun Oil Company to a total depth of 19,000 feet, this well was abandoned as a dry hole in January 1964. Gruy's reentry attempt ended with plugging and abandonment after a saltwater flow on September 17, 1978. This report is a comprehensive document detailing all events and costs relating to the Alice C. plantation well, from its initial selection as a reentry well through the plugging and abandonment operations.

The feasibility of applying geopressured-geothermal resources to direct uses  

DOE Green Energy (OSTI)

This study concludes that direct use technologies, especially desalinated water production, can contribute significantly to the value added process and the overall economic viability in developing a geopressured resource. Although agriculture and aquaculture applications are marginal projects when they are the only use of a geopressured well, the small margin of profitability can contribute to improving the overall economics of the direct use development. The added complexity from a technical and management aspect may add to the overall risk and unpredictability of the project. Six combination of direct uses received economic evaluation that resulted in 15% discounted payback periods ranging from 4 to over 10 years. Many other combinations are possible depending on the resource and market variables. Selection of appropriate technologies and sizes of applications will be established by the developer that engages in geopressured resource utilization. Currently, many areas of the country where geopressured resources are located also have surplus electrical capacity and generation, thus power utilities have been selling power for less than 2 cents per kWH, well below a reasonable breakeven value for geopressured produced electricity. However, when the energy demand of the integrated geopressured facility is large enough to install power generation equipment, operating expenses can be reduced by not paying the 10 to 12 cents per kWH utility rate. The study includes an analysis of a geothermal turbine unit installed with a desalination and an agriculture/aquaculture facility, taking advantage of the cascading energy values. Results suggest that this scenario becomes profitable only where the market price for electricity exceeds five cents per kWH.

Ratio of produced gas to produced water from DOE's EDNA Delcambre No. 1 geopressured-geothermal aquifer gas well test  

DOE Green Energy (OSTI)

A paper presented by the Institute of Gas Technology (IGT) at the Third Geopressured-Geothermal Energy Conference hypothesized that the high ratio of produced gas to produced water from the No. 1 sand in the Edna Delcambre No. 1 well was due to free gas trapped in pores by imbibition over geological time. This hypothesis was examined in relation to preliminary test data which reported only average gas to water ratios over the roughly 2-day steps in flow rate. Subsequent public release of detailed test data revealed substantial departures from the previously reported computer simulation results. Also, data now in the public domain reveal the existence of a gas cap on the aquifier tested. This paper describes IGT's efforts to match the observed gas/water production with computer simulation. Two models for the occurrence and production of gas in excess of that dissolved in the brine have been used. One model considers the gas to be dispersed in pores by imbibition, and the other model considers the gas as a nearby free gas cap above the aquifier. The studies revealed that the dispersed gas model characteristically gave the wrong shape to plots of gas production on the gas/water ratio plots such that no reasonable match to the flow data could be achieved. The free gas cap model gave a characteristically better shape to the production plots and could provide an approximate fit to the data of the edge of the free gas cap is only about 400 feet from the well.Because the geological structure maps indicate the free gas cap to be several thousand feet away and the computer simulation results match the distance to the nearby Delcambre Nos. 4 and 4A wells, it appears that the source of the excess free gas in the test of the No. 1 sand may be from these nearby wells. The gas source is probably a separate gas zone and is brought into contact with the No. 1 sand via a conduit around the No. 4 well.

DOE Green Energy (OSTI)

This report describes environmental monitoring activities carried out by Louisiana State University (LSU) under US Department of Energy Contract FC07-85NV10425 for the period 1 November 1984 through 31 December 1986. Other aspects of the LSU technical support program completed under prior contracts were covered in final form in reports preceding this one. During the contract period, the Louisiana Geological Survey, aided by subcontractors, monitored microseismic activity, land-surface subsidence, and surface and ground-water quality at three designed geopressured-geothermal test well sites in Louisiana and Texas. Don Stevenson supervised microseismic monitoring activities, and Drukell Trahan coordinated water quality and land-surface subsidence studies. This is a progress report in the sense that it discusses program components, provides raw data, and presents preliminary interpretations. The environmental monitoring program continues and will be the subject of subsequent annual reports.

DOE Green Energy (OSTI)

The Saldana Well No. 2, approximately 35 miles Southeast of the city of Laredo, Texas, was the sixth successful test of a geopressured-geothermal aquifer under the DOE Wells of Opportunity Program. The well was tested through the annulus between 7-inch casing and 2-3/8 inch tubing. The interval tested was from 9745 to 9820 feet. The geological section was the 1st Hinnant Sand, an upper member of the Wilcox Group. Produced water was injected into the Saldana Well No. 1, which was also acquired from Riddle Oil Company and converted to a disposal well. A Miocene salt water sand was perforated from 3005 to 3100 feet for disposal. One pressure drawdown flow test and one pressure buildup test were conducted during a 10-day period. A total of 9328 barrels of water was produced. The highest sustained flow rate was 1950 BWPD.

Geopressured geothermal resources of Texas: a report on legal ownership and royalty issues  

DOE Green Energy (OSTI)

Legal issues affecting ownership of the geopressured resources were examined. It was concluded that consideration of royalty interests indicates that the greatest promise for geothermal resource development would be offered if the geopressured resources were held to be entirely mineral in character. Further, the energy of the geopressured water should be held to be embraced by the standard term other minerals. (MHR)

Preliminary reservoir and subsidence simulations for the Austin Bayou geopressured geothermal prospect  

DOE Green Energy (OSTI)

For the last several years, the University of Texas at Austin (UTA) has analyzed the geopressured tertiary sandstones along the Texas Gulf Coast with the objective of locating prospective reservoirs from which geothermal energy could be recovered. Of the ''geothermal fairways'' (areas with thick sandstone bodies and estimated temperatures in excess of 300 F), the Brazoria fairway appears most promising and the Austin Bayou Prospect has been developed within this fairway. A test well (DOE 1 Martin Ranch) is currently being drilled in this area. Pending the availability of actual well test data, estimated reservoir properties have been employed in numerical simulations to study the effects of variations in reservoir properties on the projected long-term behavior of the Austin Bayou Prospect. The simulations assess the sensitivity of the reservoir behavior to variations is estimated sandstone/shale distribution, shale compressibility, and vertical shale permeability. Further, hypothetical properties for the stress-deformation behavior of the rock formations were employed in a very preliminary study of the potential ground surface displacements that might accompany fluid production.

Testing geopressured geothermal reservoirs in existing wells. Final report P. R. Girouard Well No. 1, Lafayette Parish, Louisiana. Volume I. Completion and testing  

DOE Green Energy (OSTI)

The P.R. Girouard No. 1 Well, located approximately 10 miles southeast of Lafayette, Louisiana, was the fourth successful test of a geopressured-geothermal aquifer under the Wells of Opportunity program. The well was tested through 3-1/2 inch tubing set on a packer at 14,570 feet without major problems. The geological section tested was the Oligocene Marginulina Texana No. 1 sand of upper Frio age. The interval tested was from 14,744 to 14,819 feet. Produced water was piped down a disposal well perforated from 2870 to 3000 feet in a Miocene saltwater sand. Four flow tests were conducted for sustained production rates of approximately 4000 BWPD to approximately 15,000 BWPD. The highest achieved, during a fifth short test, was 18,460 BWPD. The test equipment was capable of handling higher rates. The gas-to-water ratio was relatively uniform at approximately 40 SCF/bbl. The heating value of the gas is 970 Btu/SCF. The reservoir tests show that is is doubtful that this well would sustain production rates over 10,000 BWPD for any lengthy period from the sand zone in which it was completed. This limited flow capacity is due to the well's poor location in the reservoir and is not a result of any production deficiencies of the Marginulina Texana sand.

Factors controlling reservoir quality in tertiary sandstones and their significance to geopressured geothermal production. Annual report, May 1, 1979-May 31, 1980  

DOE Green Energy (OSTI)

Differing extents of diagenetic modification is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the Upper and Lower Texas Gulf Coast. Detailed comparison of Frio sandstones from the Chocolate Bayou/Danbury Dome area, Brazoria County, and Vicksburg sandstones from the McAllen Ranch Field area, Hidalgo County, reveals that extent of diagenetic modification is most strongly influenced by (1) detrital mineralogy and (2) regional geothermal gradients. Vicksburg sandstones from the McAllen Ranch Field area are less stable, chemically and mechanically, than Frio sandstones from the Chocolate Bayou/Danbury dome area. Vicksburg sandstones are mineralogically immature and contain greater proportions of feldspars and rock fragments than do Frio sandstones. Thr reactive detrital assemblage of Vicksubrg sandstones is highly susceptible to diagenetic modification. Susceptibility is enhanced by higher than normal geothermal gradients in the McAllen Ranch Field area. Thus, consolidation of Vicksburg sandstones began at shallower depth of burial and precipitation of authigenic phases (especially calcite) was more pervasive than in Frio sandstones. Moreover, the late-stage episode of ferroan calcite precipitation that occluded most secondary porosity in Vicksburg sandstones did not occur significantly in Frio sandstones. Therefore, regional reservoir quality of Frio sandstones from Brazoria County is far better than that characterizing Vicksburg sandstones from Hidalgo County, especially at depths suitable for geopressured geothermal energy production.

Geopressured-Geothermal Drilling and Testing Plan, Volume II, Testing Plan; Dow Chemical Co. - Dept. of Energy Dow-DOE Sweezy No. 1 Well, Vermilion Parish, Louisiana  

DOE Green Energy (OSTI)

The Dow/D.O.E. L. R. Sweezy No. 1 geopressured geothermal production well was completed in August of 1981. The well was perforated and gravel packed in approximately 50 feet of sand from 13,344 feet to 13,395 feet. Permeabilities of 6 to 914 millidarcies were measured with porosity of 25 to 36%. Static surface pressure after well clean-up was 5000 psi. At 1000 B/D flow rate the drawdown was 50 psi. The water produced in clean-up contained 100,000 ppm TDS. This report details the plan for testing this well with the goal of obtaining sufficient data to define the total production curve of the small, 939 acre, reservoir. A production time of six to nine months is anticipated. The salt water disposal well is expected to be completed and surface equipment installed such that production testing will begin by April 1, 1982. The program should be finished and reports written by February 28, 1983. The brine will be produced from the No.1 well, passed through a separator where the gas is removed, then reinjected into the No.2 (SWD) well under separator pressure. Flow rates of up to 25,000 B/D are expected. The tests are divided into a two-week short-term test and six to nine-month long-term tests with periodic downhole measurement of drawdown and buildup rates. Data obtained in the testing will be relayed by phoneline computer hookup to Otis Engineering in Dallas, Texas, where the reservoir calculations and modeling will be done. At the point where sufficient data has been obtained to reach the objectives of the program, production will be ended, the wells plugged and abandoned, and a final report will be issued.

Attitudinal survey of citizens in a potential Gulf Coast geopressured-geothermal test-well locality. Final report  

DOE Green Energy (OSTI)

The results of a mail survey used to tap the opinions of the public at large in the study area are described. Attention in that section is focused on awareness of the resource, favorability toward the impending development, concerns about the development, attitudes regarding how the development should take place, levels of community satisfaction, and perceived future problems due to community growth. An analysis is given of the 33 interviews conducted with local representatives of the financial and commercial sectors, government, industry, agriculture, and environmental groups. The main foci here are perceived problems and benefits associated with geothermal development and the local capacity for coping with strains on community services resulting from any population growth which may be generated by resource development. A comparison and synthesis of the results from the general survey and the sector interviews is included. In conclusion, policy recommendations are made for means through which to consolidate goals and to achieve resource development objectives with minimal antagonism of and problems for local citizens and community sectors.

Geothermal Well Operations and Automation in a Competitive Market  

DOE Green Energy (OSTI)

America's increasing dependence on foreign energy sources, and the national environmental initiatives, based on the increasing awareness of the need for protection of the environment, have led to the development of the Department of Energy's (DOE) domestic US alternative energy programs. One of these programs is the current US Gulf Coast Geopressured-Geothermal Program, conducted at three sites in Louisiana and Texas. Excellent results have been obtained in reaching the objectives for this production operation and energy conversion project, which are: (1) to determine the size of geopressured-geothermal reservoirs and the drive mechanisms by long-term, high volume, flow testing; (2) prove long-term injectability of large volumes of spent brine; (3) develop modified scale inhibitor treatment procedures; (4) develop methods for reduction of erosion/corrosion; (5) develop technology for automated operation of geopressured-geothermal production system; and (6) develop technology to produce power economically from the geopressured-geothermal resources. The long-term flow test at the Gladys McCall site has shown the producing reservoir is many times it original, projected size. Flow tests are being conducted at the Pleasant Bayou site in Texas. Another reservoir, at the Hulin site in Louisiana, remains for initiation of testing, at a time to be determined. Gas sales and electrical power generation from the geopressured-geothermal resources have proven that these are reliable alternative power sources. Continuing work is being done for field automation to improve the economics of these operations.

Consolidation of geologic studies of geopressured-geothermal resources in Texas: Barrier-bar tidal-channel reservoir facies architecture, Jackson Group, Prado field, South Texas; Final report  

DOE Green Energy (OSTI)

Sandstone reservoirs in the Jackson barrier/strandplain play are characterized by low recovery efficiencies and thus contain a large hydrocarbon resource target potentially amenable to advanced recovery techniques. Prado field, Jim Hogg County, South Texas, has produced over 23 million bbl of oil and over 32 million mcf gas from combination structural-stratigraphic traps in the Eocene lower Jackson Group. Hydrocarbon entrapment at Prado field is a result of anticlinal nosing by differential compaction and updip pinch-out of barrier bar sandstone. Relative base-level lowering resulted in forced regression that established lower Jackson shoreline sandstones in a relatively distal location in central Jim Hogg County. Reservoir sand bodies at Prado field comprise complex assemblages of barrier-bar, tidal-inlet fill, back-barrier bar, and shoreface environments. Subsequent progradation built the barrier-bar system seaward 1 to 2 mi. Within the barrier-bar system, favorable targets for hydrocarbon reexploration are concentrated in tidal-inlet facies because they possess the greatest degree of depositional heterogeneity. The purpose of this report is (1) to describe and analyze the sand-body architecture, depositional facies variations, and structure of Prado field, (2) to determine controls on distribution of hydrocarbons pertinent to reexploration for bypassed hydrocarbons, (3) to describe reservoir models at Prado field, and (4) to develop new data affecting the suitability of Jackson oil fields as possible candidates for thermally enhanced recovery of medium to heavy oil.

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.

The report then overlays onto this 'big picture' three types of geothermal technologies: conventional hydrothermal systems; emerging technologies such as enhanced engineered geothermal systems (EGS) and geopressured geothermal; and geothermal co-production with existing oil and gas wells. Each category of geothermal technology has its own set of interconnection issues, and these are examined separately for each. The report draws conclusions about each technology's market affinities as defined by factors related to transmission and distribution infrastructure. It finishes with an assessment of selected markets with known geothermal potential, identifying those that offer the best prospects for near-term commercial development and for demonstration projects.

This report discusses Test Campaign TC12 of the Kellogg Brown & Root, Inc. (KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (SW) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using a particulate control device (PCD). While operating as a gasifier, either air or oxygen can be used as the oxidant. Test run TC12 began on May 16, 2003, with the startup of the main air compressor and the lighting of the gasifier start-up burner. The Transport Gasifier operated until May 24, 2003, when a scheduled outage occurred to allow maintenance crews to install the fuel cell test unit and modify the gas clean-up system. On June 18, 2003, the test run resumed when operations relit the start-up burner, and testing continued until the scheduled end of the run on July 14, 2003. TC12 had a total of 733 hours using Powder River Basin (PRB) subbituminous coal. Over the course of the entire test run, gasifier temperatures varied between 1,675 and 1,850 F at pressures from 130 to 210 psig.

This report discusses test campaign GCT3 of the Halliburton KBR transport reactor train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The transport reactor is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using one of two possible particulate control devices (PCDs). The transport reactor was operated as a pressurized gasifier during GCT3. GCT3 was planned as a 250-hour test run to commission the loop seal and continue the characterization of the limits of operational parameter variations using a blend of several Powder River Basin coals and Bucyrus limestone from Ohio. The primary test objectives were: (1) Loop Seal Commissioning--Evaluate the operational stability of the loop seal with sand and limestone as a bed material at different solids circulation rates and establish a maximum solids circulation rate through the loop seal with the inert bed. (2) Loop Seal Operations--Evaluate the loop seal operational stability during coal feed operations and establish maximum solids circulation rate. Secondary objectives included the continuation of reactor characterization, including: (1) Operational Stability--Characterize the reactor loop and PCD operations with short-term tests by varying coal feed, air/coal ratio, riser velocity, solids circulation rate, system pressure, and air distribution. (2) Reactor Operations--Study the devolatilization and tar cracking effects from transient conditions during transition from start-up burner to coal. Evaluate the effect of process operations on heat release, heat transfer, and accelerated fuel particle heat-up rates. Study the effect of changes in reactor conditions on transient temperature profiles, pressure balance, and product gas composition. (3) Effects of Reactor Conditions on Syngas Composition--Evaluate the effect of air distribution, steam/coal ratio, solids circulation rate, and reactor temperature on CO/CO{sub 2} ratio, H{sub 2}/converted carbon ratio, gasification rates, carbon conversion, and cold and hot gas efficiencies. Test run GCT3 was started on December 1, 2000, with the startup of the thermal oxidizer fan, and was completed on February 1, 2001. This test was conducted in two parts; the loop seal was commissioned during the first part of this test run from December 1 through 15, which consisted of hot inert solids circulation testing. These initial tests provided preliminary data necessary to understand different parameters associated with the operation and performance of the loop seal. The loop seal was tested with coal feed during the second part of the test run and additional data was gathered to analyze reactor operations and to identify necessary modifications to improve equipment and process performance. In the second part of GCT3, the gasification portion of the test, from January 20 to February 1, 2001, the mixing zone and riser temperatures were varied between 1,675 and 1,825 F at pressures ranging from 200 to 240 psig. There were 306 hours of solid circulation and 184 hours of coal feed attained in GCT3.

Environmental considerations and economic implications in the development of geothermal energy  

SciTech Connect

"Any time that man has activity, there will be an impact on the environment. We can talk about minimizing the effects of this activity, but the real answer to working out environmental problems is environmental management. Nevertheless, the cookbook-type regulations severely restrict development of environmental-management options. A better solution would be to have a number of ways to predict as accurately as possible the environmental or ecosystem response to man's activities, so that rational judgments can be made by society as to the best operational criteria.… Certainly if geopressured geothermal-resource development becomes a reality, the options chosen for environmental management may not be pleasing to everyone, but, hopefully, decisions will be made to benefit the most people, not only for a short time but for the generations to follow."

DOE Green Energy (OSTI)

The overall objective of the project was to study the seismic effects of fluid withdrawal from deep reservoirs and its subsequent reinjection closer to the surface. This effort included the design and installation of a hardware system and development of a study approach to monitor dynamic deformation in the Gulf Coast environment. Over the long term, insight gained into the ground deformation process (specifically ground subsidence) may potentially allow the integration of observations of individual phenomena into predictive tools for future use in ground subsidence studies. The value of a seismic monitoring network as a predictive tool can only be evaluated by an integrated program to study ground and instrument performance with time. Integrating extended real time monitoring of potential seismic precursors to significant displacements may represent the first integrated study of subsidence undertaken in the Gulf Coast region.

Geopressured-geothermal well report. Volume I. Drilling and completion  

DOE Green Energy (OSTI)

Gladys McCall site activities are covered through the completion of the test well and salt water disposal well. The test well was drilled to a total depth of 16,510 feet, then plugged back to 15,831 feet. Three 4'' diameter diamond cores were taken for analysis. An existing well on site, the Getty-Butts Gladys McCall No. 1, was reentered and completed to a depth of 3514 feet as a salt water disposal well. The geologic interpretation of the Gladys McCall site indicated target sands for testing at 15,080 feet through 15, 831 feet. Reservoir fluid temperature at this depth is estimated to be approximately 313/sup 0/F and pressure is estimated to be +-12,800 psi. The preliminary reservoir volume estimate is 3.6 billion barrels of brine. The design wells program includes environmental monitoring of the Gladys McCall site by Louisiana State University. Field stations are set up to monitor surface and ground water quality, subsidence, land loss and shoreline erosion, and seismicity. As of December 31, 1981 the study shows no significant impact on the environment by site operations.

Investigation and evaluation of geopressured-geothermal wells. Final report  

DOE Green Energy (OSTI)

This well was approved for reentry and test operations after consideration of a number of reentry prospects in Cameron Parish. This was a marsh location that required 2.3 miles of board road and replacement of two bridges. Road work was commenced on June 19, 1978, and site preparation was completed on October 25. The drilling rig moved on location on November 2. This rig was released on December 16. Reentry operations were completely unsuccessful because of failure to effect a tieback of the 7'' casing. The plugging and abandonment records filed with the Louisiana Department of Conservtion indicated that the top of the 7'' casing was at or near the base of the 10-3/4'' casing when the well was plugged. These records did not specify that the 7'' casing had been dynamited one or more times during the recovery operation. Numerous attempts were made to locate and condition the 7'' casing for tying back to the surface. All these were unsuccessful. The top of the 7'' casing was never clearly located, or if located was subsequently lost, and therefore it was not possible to cut and recover the damaged section in order to effect a tieback. The total cost of the attempted reentry was approximately $1,925,000. Of this amount, some $444,000 was spent on road and site preparation and disposal well. This expenditure can be salvaged in the event a decision is made to redrill the well.

Testing geopressured geothermal reservoirs in existing wells. Annual report  

DOE Green Energy (OSTI)

This contract called for the acquisition and testing of Wells of Opportunity. Wells of Opportunity are located by screening published information on oil industry activity and through personal contacts with oil operators. This process resulted in recommendation of 21 candidate wells to the DOE for the WOO program. Of the 21 wells recommended, 7 were accepted. Six of these 7 were acquired for testing. Three wells have been tested, and the fourth and fifth will be tested early in 1981. Preliminary test results are briefly described and are shown in a table. The actual testing schedule and the originally proposed schedule matched very closely. Cumulative costs through November 1980 were approximately $6.5 million and compare to an estimate of $8.5 million for the same period. A graphical comparison of actual versus estimated costs is given.

Hulin Geopressure-geothermal test well: First order levels  

DOE Green Energy (OSTI)

The purpose of this survey was to level through and establish elevations for existing benchmarks along LA Highway No. 685 from Erath, Louisiana south to the well site. The leveling was performed in April 1991, and was accomplished using procedures and equipment identical to that used by the National Geodetic Survey for First Order Class I Leveling. The leveling began on benchmark NGS T-361 located in Erath, Louisiana and the published elevation of 5.271 feet was used for this survey. On this survey a new benchmark, HU-18 was set on a concrete slab in the well site to observe the subsidence of the ground surface. Also, benchmark No.8 could not be found. A two hour search was made with no results. At this leveling it was noted that an error was made. A metric D.E. was used for the well head elevation instead of feet. This error has been corrected in this report.

Testing geopressured geothermal reservoirs in existing wells: Detailed completion prognosis for geopressured-geothermal well of opportunity, prospect #7  

DOE Green Energy (OSTI)

This book is a detailed prognosis covering the acquisition, completion, drilling, testing and abandonment of the Frank A. Godchaux, III, Well No. 1 under the Wells of Opportunity Program. The well is located approximately 12 miles southeast of the city of Abbeville, Louisiana. Eaton Operating Company proposes to test a section of the Planulina sand at a depth ranging from 15,584 to 15,692 feet. The reservoir pressure is estimated to be 14,480 psi and the temperature of the formation water is expected to be 298 F. The water salinity is calculated to be 75,000 ppm. The well is expected to produce 20,000 barrels of water per day with a gas content of 44 standard cubic feet pre barrel. The well was acquired from C and K Petroleu, Inc. on March 20, 1981. C and K abandoned the well at a total depth of 16,000 feet. The well has a 7-5/8 inches liner set at 13,387 feet. Eaton proposes to set 5-1/2 inch casing at 16,000 feet and produce the well through the casing using a 2-3/8 inch tubing string for wireline protection and for pressure control. A 4,600 foot saltwater disposal well will be drilled on the site and testing will be conducted similar to previous Eaton tests. The total estimated cost to perform the work is $2,959,000. An optional test from 14,905 to 15,006 feet may be performed after the original test and will require a workover with a rig on location to perform the plugback. The surface production equipment utilized on previous Eaton WOO tests will be utilized on this test. This equipment has worked satisfactorily and all parties involved in the testing are familiar with its operation. The Institute of Gas Technology and Mr. Don Clark will handle the sampling and testing and reservoir evaluation, respectively, as on the previous Eaton tests.

Role of nuclear power in the Philippine power development program  

SciTech Connect

The reintroduction of nuclear power in the Philippines is favored by several factors such as: the inclusion of nuclear energy in the energy sector of the science and technology agenda for national development (STAND); the Large gap between electricity demand and available local supply for the medium-term power development plan; the relatively lower health risks in nuclear power fuel cycle systems compared to the already acceptable power systems; the lower environmental impacts of nuclear power systems compared to fossil fuelled systems and the availability of a regulatory framework and trained personnel who could form a core for implementing a nuclear power program. The electricity supply gap of 9600 MW for the period 1993-2005 could be partly supplied by nuclear power. The findings of a recent study are described, as well as the issues that have to be addressed in the reintroduction of nuclear power.

Geothermal Power Development in the Phillippines  

DOE Green Energy (OSTI)

The generation of electric power to meet the needs of industrial growth and dispersal in the Philippines is aimed at attaining self-reliance through availment of indigenous energy resources. The Philippines by virtue of her position in the high-heat flow region has in abundance a number of exploitable geothermal fields located all over the country. Results indicate that the geothermal areas of the Philippines presently in various stages of exploration and development are of such magnitude that they can be relied on to meet a significant portion of the country's power need. Large scale geothermal energy for electric power generation was put into operation last year with the inauguration of two 55-MW geothermal generating units at Tiwi, Albay in Southern Luzon. Another two 55-MW units were added to the Luzon Grid in the same year from Makiling-Banahaw field about 70 kilometers south of Manila. For 1979 alone, therefore, 220-MW of generating capacity was added to the power supply coming from geothermal energy. This year a total of 220-MW power is programmed for both areas. This will bring to 443-MW of installed generating capacity from geothermal energy with 3-MW contributed by the Tongonan Geothermal pilot plant in Tongonan, Leyte, Central Philippines in operation since July 1977. Financial consideration of Philippine experience showed that electric power derived from geothermal energy is competitive with other sources of energy and is a viable source of baseload electric power. Findings have proven the technical and economic acceptability of geothermal energy resources development. To realize the benefits that stem from the utilization of indigenous geothermal resources and in the light of the country's ever increasing electric power demand and in the absence of large commercial oil discovery in the Philippines, geothermal energy resource development has been accelerated anew. The program includes development of eight fields by 1989 by adding five more fields to the currently developed and producing geothermal areas.

Investigation and Evaluation of Geopressured-Geothermal Wells; Detailed Reentry Prognosis for Geopressure-Geothermal Testing of the Watkins-Miller No.1 Well, Cameron Parish, Louisiana  

DOE Green Energy (OSTI)

This prospect was drilled as the Superior Oil Company No. 1 Watkins-Miller, located in Section 5, T15S, R5W, Cameron Parish, Louisiana. The well site is just north of lot 39 on Indian Point Island and is readily accessible from State Highway 82 via a shell road which is in good condition. This location is shown on the lower portion of the USGS topographic sheet ''Grand Lake West''; a portion of this sheet is included. Superior Oil completed this well in late 1970 as a dual gas producer in sands between 11,150 and 11,250 feet and abandoned it in December 1974. This well was initially selected as the first Geo reentry candidate but was deferred when the landowner refused to grant reentry and test rights. He has, however, now indicated that he would be willing to grant those rights for a fee of $50,000. In view of the need for an alternate well to replace the State Lease 4183 No. 1, Gruy Federal has thoroughly reviewed alternate wells and concluded that the Watkins-Miller No. 1 requires minimal site preparation and is the reentry well of choice.

Green Power Network: Community Renewable Energy Development  

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

Community Renewable Energy Development Community Renewable Energy Development Community renewable energy development can take many forms, including offering a community renewable energy program, developing a community green power challenge, or developing local renewable projects. Some communities are installing renewable energy on local government facilities. For example, the City of Boulder installed a biomass burner to heat its county jail. Other local governments are installing solar on school buildings or community centers. For more information, see examples of state and local governments that have installed on-site renewable energy systems. Community Renewable Energy Programs Community renewable energy programs allow customers to purchase a share of a renewable system developed in the local community and receive the benefits of the energy that is produced by their share. For example, the Holy Cross Energy solar project in El Jebel, Colorado is an 80 kilowatt (kW) photovoltaic system supported by 18 community participants that purchase shares at an upfront cost of $3.15 per watt ($3,150 per kW) and then receive a credit on their bill each month at a rate of $0.11 per kilowatt-hour.

The Power Systems Development Facility -- Current status  

Science Conference Proceedings (OSTI)

Southern Company Services, Inc. (SCS) has entered into a cooperative agreement with the US Department of Energy (DOE) to build and operate the Power Systems Development Facility (PSDF), currently under construction in Wilsonville, Alabama, 40 miles southeast of Birmingham. The objectives of the PSDF are to develop advanced coal-fired power generation technologies through testing and evaluation of hot gas cleanup systems and other major components at the pilot scale. The performance of components will be assessed and demonstrated in an integrated mode of operation and at a component size readily scaleable to commercial systems. The facility will initially contain five modules: (1) a transport reactor gasifier and combustor, (2) an advanced pressurized fluidized-bed combustion (APFBC) system, (3) a particulate control module, (4) an advanced burner-gas turbine module, and (5) a fuel cell. The five modules will initially be configured into two separate test trains, the transport reactor train (2 tons/hour of coal feed) and the APFBC train (3 tons/hour of coal feed). In addition to a project description, the project design and construction status, preparations for operations, and project test plans are reported in this paper.

Analysis of three geopressured geothermal aquifer-natural gas fields; Duson Hollywood and Church Point, Louisiana  

DOE Green Energy (OSTI)

The available well logs, production records and geological structure maps were analyzed for the Hollywood, Duson, and Church Point, Louisiana oil and gas field to determine the areal extent of the sealed geopressured blocks and to identify which aquifer sands within the blocks are connected to commercial production of hydrocarbons. The analysis showed that over the depth intervals of the geopressured zones shown on the logs essentially all of the sands of any substantial thickness had gas production from them somewhere or other in the fault block. It is therefore expected that the sands which are fully brine saturated in many of the wells are the water drive portion of the producing gas/oil somewhere else within the fault block. In this study only one deep sand was identified, in the Hollywood field, which was not connected to a producing horizon somewhere else in the field. Estimates of the reservoir parameters were made and a hypothetical production calculation showed the probable production to be less than 10,000 b/d. The required gas price to profitably produce this gas is well above the current market price.

Solvent extraction of methane from simulated geopressured-geothermal fluids: sub-pilot test results  

DOE Green Energy (OSTI)

The extraction of methane dissolved in 15 wt % sodium chloride solution at 150/sup 0/C and 1000 psi has been demonstrated using n-hexadecane as the solvent in a sub-pilot scale extraction column operated in a continuous, countercurrent flow mode. Greater than 90% recovery of methane was obtained with solvent/brine mass flow ratios in the range of .040 to .045. The height of an ideal stage in this experimental Elgin-type spray column is estimated to be 1.5 ft. Application of this process on actual geopressured fluids is technically feasible, and when combined with direct drive injection disposal is economically attractive. Design and operation of a methane saturated-brine supply system to provide simulated geopressured fluid continuously at 150/sup 0/C and 1000 psi are also described.

Evaluation of NEPA-based environmental commitments at four geopressured geothermal design wells  

DOE Green Energy (OSTI)

This study verifies the implementation and effectiveness of environmental mitigation and monitoring commitments made by the US Department of Energy in National Environmental Policy Act documents (Environmental Assessments (EAs)) prepared for four geopressure design well projects, one in Texas and three in Louisiana. The evaluation was based on visits to the project sites conducted by Oak Ridge National Laboratory staff in August 1982 and April 1983, and on a review of monitoring and project activity reports provided by DOE subcontractors. Subcontractors responsible for drilling and testing activities at the well sites adequately implemented most of the mitigation measures described in each project's EA. Exceptions included the lack of impermeable liners for drilling mud pits at three sites and the lack of a ring levee at one site. Water quality, noise, and air monitoring were not performed as strictly as outlined in the EAs. A review of the data collected to date indicates that no significant environmental degradation has occurred. Additional or future monitoring needs, especially with regard to subsidence, microseismicity, and groundwater and soil sampling were recommended.

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.

ZERO EMISSION POWER GENERATION TECHNOLOGY DEVELOPMENT  

SciTech Connect

Clean Energy Systems (CES) was previously funded by DOE's ''Vision 21'' program. This program provided a proof-of-concept demonstration that CES' novel gas generator (combustor) enabled production of electrical power from fossil fuels without pollution. CES has used current DOE funding for additional design study exercises which established the utility of the CES-cycle for retrofitting existing power plants for zero-emission operations and for incorporation in zero-emission, ''green field'' power plant concepts. DOE funding also helped define the suitability of existing steam turbine designs for use in the CES-cycle and explored the use of aero-derivative turbines for advanced power plant designs. This work is of interest to the California Energy Commission (CEC) and the Norwegian Ministry of Petroleum & Energy. California's air quality districts have significant non-attainment areas in which CES technology can help. CEC is currently funding a CES-cycle technology demonstration near Bakersfield, CA. The Norwegian government is supporting conceptual studies for a proposed 40 MW zero-emission power plant in Stavager, Norway which would use the CES-cycle. The latter project is called Zero-Emission Norwegian Gas (ZENG). In summary, current engineering studies: (1) supported engineering design of plant subsystems applicable for use with CES-cycle zero-emission power plants, and (2) documented the suitability and availability of steam turbines for use in CES-cycle power plants, with particular relevance to the Norwegian ZENG Project.

Advanced Power Plant Development and Analyses Methodologies  

DOE Green Energy (OSTI)

Under the sponsorship of the U.S. Department of Energy/National Energy Technology Laboratory, a multi-disciplinary team led by the Advanced Power and Energy Program of the University of California at Irvine is defining the system engineering issues associated with the integration of key components and subsystems into advanced power plant systems with goals of achieving high efficiency and minimized environmental impact while using fossil fuels. These power plant concepts include ''Zero Emission'' power plants and the ''FutureGen'' H{sub 2} co-production facilities. The study is broken down into three phases. Phase 1 of this study consisted of utilizing advanced technologies that are expected to be available in the ''Vision 21'' time frame such as mega scale fuel cell based hybrids. Phase 2 includes current state-of-the-art technologies and those expected to be deployed in the nearer term such as advanced gas turbines and high temperature membranes for separating gas species and advanced gasifier concepts.

The DOE/SCS Power Systems Development Facility  

Science Conference Proceedings (OSTI)

The use of coal for power generation has come under increasing environmental scrutiny over the past five years. Advances in coal-based power generation technology will continue to develop towards systems that have high efficiency, environmental superiority and lower or sustainable cost-of-electricity compared to current coal-based technology. Emerging power generation technologies that work toward these goals include integrated gasification combined-cycle (IGCC) and pressurized fluidized-bed combustion (PFBC). One method for improving the efficiency and lowering the capital cost further for advanced power plants utilizing coal is by employing hot gas cleanup. Although hot gas cleanup has the potential for improving the viability of coal-based power generation, the removal of hot particulates from the gas stream has proven to be a challenging task. The demonstration of particulate control devices (PCDS) under realistic conditions for advanced power generation remains the single most important area for development. With the Southern Company`s commitment to be a major supplier of electricity worldwide and our continued use of coal as a primary fuel source, Southern Company Services (SCS) has entered into a cooperative effort with the Department of Energy (DOE) Morgantown Energy Technology Center (METC) to develop a facility where component and system integration tests can be carried out for advanced coal-based power plants. The Power Systems Development Facility (PSDF) is being designed to be a flexible facility that will address the development of the PCDs required for advanced coal-based power generation systems.

Photovoltaic power conditioners: Development, evolution, and the next generation  

DOE Green Energy (OSTI)

Market-place acceptance of utility-connected photovoltaic (PV) power generation systems and their accelerated installation into residential and commercial applications are heavily dependent upon the ability of their power conditioning subsystems (PCS) to meet high reliability, low cost, and high performance goals. Many PCS development efforts have taken place over the last 15 years, and those efforts have resulted in substantial PCS hardware improvements. These improvements, however, have generally fallen short of meeting many reliability, cost and performance goals. Continuously evolving semiconductor technology developments, coupled with expanded market opportunities for power processing, offer a significant promise of improving PCS reliability, cost and performance, as they are integrated into future PCS designs. This paper revisits past and present development efforts in PCS design, identifies the evolutionary improvements and describes the new opportunities for PCS designs. The new opportunities are arising from the increased availability and capability of semiconductor switching components, smart power devices, and power integrated circuits (PICS).

PFBC perspectives at the Power Systems Development Facility  

Science Conference Proceedings (OSTI)

The use of coal for power generation has come under increasing environmental scrutiny over the past five years. Advances in coal-based power generation technology will develop systems that have high efficiency, environmental superiority and lower cost of electricity compared to current coal-based technology. Advanced pressurized-fluidized-bed combustion (APFBC) is one `of the promising emerging power generation technologies striving to achieve these goals. One method of improving the efficiency and lowering the capital cost further for advanced power plants utilizing coal is by employing hot gas cleanup. Although hot gas cleanup has the potential for improving the viability of coal-based power generation, the removal of hot particulates from the gas stream has proven to be a challenging task. The demonstration of APFBC technology and the particulate control devices (PCDs) under realistic conditions for advanced power generation remain important areas for development. The Power Systems Development Facility (PSDF) is being designed to be a flexible facility that will address the development of the PCDs and an advanced second-generation PFBC technology. With the progress made in the last decade, the basic concepts of PFBC technology can be achieved through a number of different flowsheets and reactor configurations. The choices made in developing the flowsheets and the choices made in designing the equipment in order to improve the reliability of operation may well dictate, along with the actual data from operation, the process efficiencies and the capital costs that can be achieved.

Tokamak Physics Experiment (TPX) power supply design and development  

SciTech Connect

The Tokamak Physics Experiment (TPX) is an advanced tokamak project aimed at the production of quasi-steady state plasmas with advanced shape, heating, and particle control. TPX is to be built at the Princeton Plasma Physics Laboratory (PPPL) using many of the facilities from the Tokamak Fusion Test Reactor (TFTR). TPX will be the first tokamak to utilize superconducting (SC) magnets in both the toroidal field (TF) and poloidal field (PF) systems. This new feature requires a departure from the traditional tokamak power supply schemes. This paper describes the plan for the adaptation of the PPPL/FTR power system facilities to supply TPX. Five major areas are addressed, namely the AC power system, the TF, PF and Fast Plasma Position Control (FPPC) power supplies, and quench protection for the TF and PF systems. Special emphasis is placed on the development of new power supply and protection schemes.

Turbine-generator set development for power generation  

DOE Green Energy (OSTI)

The goal of this effort was to design, develop, and demonstrate an integrated turbine genset suitable for the power generation requirements of a hybrid automotive propulsion system. The result of this effort would have been prototype generator hardware including controllers for testing and evaluation by Allison Engine Company. The generator would have been coupled to a suitably sized and configured gas turbine engine, which would operate on a laboratory load bank. This effort could lead to extensive knowledge and design capability in the most efficient generator design for hybrid electric vehicle power generation and potentially to commercialization of these advanced technologies. Through the use of the high-speed turbines as a power source for the hybrid-electric vehicles, a significant reduction in nitrous oxides emissions would be achieved when compared to those of conventional gas powered vehicles.

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.

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.

The Power Systems Development Facility at Wilsonville, Alabama  

Science Conference Proceedings (OSTI)

One of the Morgantown Energy Technology Center`s (METC`s) goals is to: {open_quotes}Commercialize Advanced Power Systems with improved environmental performance, higher efficiency, and lower cost. {close_quotes} Advanced coal-based power generation systems include Integrated Gasification Combined Cycle (IGCC), Pressurized Fluidized- Bed Combustion (PFBC), and Integrated Gasification/Fuel Cell systems. The strategy for achieving this goal includes: (1) Show the improved performance and lower cost of Advanced Power Systems through successful Clean Coal Technology demonstration projects, (2) Build and operate Technology Integration Sites in partnership with U.S. Industry (these sites will resolve key technology issues and effect continuous product improvement, and these partnerships result in leveraging of research and development (R&D) funds), and (3) Set up partnerships with other agencies and organizations such as Electric Power Research Institute (EPRI) to leverage R&D funds and skills. Demonstration of practical high-temperature particulate control devices (PCD`s) is crucial to the evolution of advanced, high- efficiency coal-based power generation systems. There are stringent particulate requirements for the fuel gas for both turbines and fuel cells. In turbines, the particulates cause erosion and chemical attack of the blade surfaces. In fuel cells, the particulates cause blinding of the electrodes. Filtration of the incoming, hot, pressurized gas is required to protect these units. Although filtration can presently be performed by first cooling the gas, the system efficiency is reduced. Development of high temperature, high pressure filtration is necessary to achieve high efficiency and extend the lifetime of downstream components to acceptable levels.

Toshiba's developments on construction techniques of nuclear power plants  

SciTech Connect

Reliable and economic energy supplies are fundamental requirements of energy policies in Japan. To accomplish these needs, nuclear power plants are being increased in Japan. In recent years, construction cost increases and schedule extensions have affected the capital cost of nuclear energy, compared with fossil power plants, due to lower costs of oil and coal. On the other hand, several severe regulations have been applied to nuclear power plant designs. High-quality and cooperative engineering and harmonized design of equipment and parts are strongly required. Therefore, reduced construction costs and scheduling, as well as higher quality and reliability, are the most important items for nuclear industry. Toshiba has developed new construction techniques, as well as design and engineering tools for control and management, that demonstrate the positive results achieved in the shorter construction period of 1100-MW(electric) nuclear power plants. The normal construction period so far is 64 months, whereas the current construction period is 52 months. (New construction techniques are partially applied). In future years, the construction period will be lowered to 48 months. (New construction techniques are fully applied). A construction period is defined as time from the start of rock inspection to the start of commercial operation.

Power conditioning development for the National Ignition Facility  

DOE Green Energy (OSTI)

The National Ignition Facility (NIF) is a high energy glass laser system and target chamber that will be used for research in inertial confinement fusion. The 192 beams of the NIF laser system are pumped by over 8600 Xenon flashlamps. The power conditioning system for NIF must deliver nearly 300 MJ of energy to the flashlamps in a cost effective and reliable manner. The present system design has over 200 capacitive energy storage modules that store approximately 1.7 MJ each and deliver that energy through a single switch assembly to 20 parallel sets of two series flashlamps. Although there are many possible system designs, few will meet the aggressive cost goals necessary to make the system affordable. Sandia National Laboratory (SNL) and Lawrence Livermore National Laboratory (LLNL) are developing the system and component technologies that will be required to build the power conditioning system for the National Ignition Facility. This paper will describe the ongoing development activities for the NIF power conditioning system.

The PSDF is an engineering scale demonstration of key features of advanced coal-fired power systems, including a KBR Transport Gasifier, a hot gas particulate control device, advanced syngas cleanup systems, and high-pressure solids handling systems. This report summarizes the results of TC22, the first test campaign using a high moisture lignite from Mississippi as the feedstock in the modified Transport Gasifier configuration. TC22 was conducted from March 24 to April 17, 2007. The gasification process was operated for 543 hours, increasing the total gasification operation at the PSDF to over 10,000 hours. The PSDF gasification process was operated in air-blown mode with a total of about 1,080 tons of coal. Coal feeder operation was challenging due to the high as-received moisture content of the lignite, but adjustments to the feeder operating parameters reduced the frequency of coal feeder trips. Gasifier operation was stable, and carbon conversions as high as 98.9 percent were demonstrated. Operation of the PCD and other support equipment such as the recycle gas compressor and ash removal systems operated reliably.

ANEMOS: Development of a Next Generation Wind Power  

E-Print Network (OSTI)

This paper presents the objectives and the research work carried out in the frame of the ANEMOS project on short-term wind power forecasting. The aim of the project is to develop accurate models that substantially outperform current state-of-the-art methods, for onshore and offshore wind power forecasting, exploiting both statistical and physical modeling approaches. The project focus on prediction horizons up to 48 hours ahead and investigates predictability of wind for higher horizons up to 7 days ahead useful i.e. for maintenance scheduling. Emphasis is given on the integration of highresolution meteorological forecasts. For the offshore case, marine meteorology is considered as well as information by satellite-radar images. An integrated software platform, `ANEMOS', is developed to host the various models. This system will be installed by several utilities for on-line operation at onshore and offshore wind farms for prediction at a local, regional and national scale. The applications include different terrain types and wind climates, on- and offshore cases, and interconnected or island grids. The on-line operation by the utilities will allow validation of the models and an analysis of the value of wind prediction for a competitive integration of wind energy in the developing liberalized electricity markets in the EU.

Subsurface and seismic investigation of the geopressured-geothermal potential of the Abbeville area of south Louisiana  

DOE Green Energy (OSTI)

The structure investigated is a basin roughly bounded by the Abbeville Dome on the west, the Erath Dome on the southeast and the Grosse Isle Dome on the northeast and whose center is located at approximately Section 31 T14S R4E. The geopressured sands investigated are below approximately 12,800 feet (3901 M) in the center of the basin and consist of two groups of rather thin, discontinuous, marly sands. These two groups, rather arbitrarily defined, are termed the upper and lower geopressured sands and the following map types and analyses have been derived from subsurface data of each: structure, temperature, pressure, salinity and net sand maps; and porosity, permeability and methane content analyses.

Frio sandstone reservoirs in the deep subsurface along the Texas Gulf Coast: their potential for production of geopressured geothermal energy  

DOE Green Energy (OSTI)

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 leat 30 percent 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 feet of methane in solution in this water. Only 10 percent of the water and methane (1 billion barrels of water and 40 billion cubic feet of methane) will be produced without reinjection of the waste water into the producing formation. Reservoir simulation studies indicate that 90 percent of the methane can be produced with reinjection. 106 figures.

Testing geopressured geothermal reservoirs in existing wells: Pauline Kraft Well No. 1, Nueces County, Texas. Final report  

DOE Green Energy (OSTI)

The Pauline Kraft Well No. 1 was originally drilled to a depth of 13,001 feet and abandoned as a dry hole. The well was re-entered in an effort to obtain a source of GEO/sup 2/ energy for a proposed gasohol manufacturing plant. The well was tested through a 5-inch by 2-3/8 inch annulus. The geological section tested was the Frio-Anderson sand of Mid-Oligocene age. The interval tested was from 12,750 to 12,860 feet. A saltwater disposal well was drilled on the site and completed in a Micocene sand section. The disposal interval was perforated from 4710 to 4770 feet and from 4500 to 4542 feet. The test well failed to produce water at substantial rates. Initial production was 34 BWPD. A large acid stimulation treatment increased productivity to 132 BWPD, which was still far from an acceptable rate. During the acid treatment, a failure of the 5-inch production casing occurred. The poor production rates are attributed to a reservoir with very low permeability and possible formation damage. The casing failure is related to increased tensile strain resulting from cooling of the casing by acid and from the high surface injection pressure. The location of the casing failure is now known at this time, but it is not at the surface. Failure as a result of a defect in a crossover joint at 723 feet is suspected.

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.

Power Systems Development Facility Gasification Test Campaign TC25  

DOE Green Energy (OSTI)

In support of technology development to utilize coal for efficient, affordable, and environmentally clean power generation, the Power Systems Development Facility (PSDF), located in Wilsonville, Alabama, routinely demonstrates gasification technologies using various types of coals. The PSDF is an engineering scale demonstration of key features of advanced coal-fired power systems, including a KBR Transport Gasifier, a hot gas particulate control device, advanced syngas cleanup systems, and high-pressure solids handling systems. This report summarizes the results of TC25, the second test campaign using a high moisture lignite coal from the Red Hills mine in Mississippi as the feedstock in the modified Transport Gasifier configuration. TC25 was conducted from July 4, 2008, through August 12, 2008. During TC25, the PSDF gasification process operated for 742 hours in air-blown gasification mode. Operation with the Mississippi lignite was significantly improved in TC25 compared to the previous test (TC22) with this fuel due to the addition of a fluid bed coal dryer. The new dryer was installed to dry coals with very high moisture contents for reliable coal feeding. The TC25 test campaign demonstrated steady operation with high carbon conversion and optimized performance of the coal handling and gasifier systems. Operation during TC25 provided the opportunity for further testing of instrumentation enhancements, hot gas filter materials, and advanced syngas cleanup technologies. The PSDF site was also made available for testing of the National Energy Technology Laboratory's fuel cell module and Media Process Technology's hydrogen selective membrane with syngas from the Transport Gasifier.

In support of technology development to utilize coal for efficient, affordable, and environmentally clean power generation, the Power Systems Development Facility (PSDF), located in Wilsonville, Alabama, routinely demonstrates gasification technologies using various types of coals. The PSDF is an engineering scale demonstration of key features of advanced coal-fired power systems, including a KBR Transport Gasifier, a hot gas particulate control device, advanced syngas cleanup systems, and high-pressure solids handling systems. This report summarizes the results of TC24, the first test campaign using a bituminous coal as the feedstock in the modified Transport Gasifier configuration. TC24 was conducted from February 16, 2008, through March 19, 2008. The PSDF gasification process operated for about 230 hours in air-blown gasification mode with about 225 tons of Utah bituminous coal feed. Operational challenges in gasifier operation were related to particle agglomeration, a large percentage of oversize coal particles, low overall gasifier solids collection efficiency, and refractory degradation in the gasifier solids collection unit. The carbon conversion and syngas heating values varied widely, with low values obtained during periods of low gasifier operating temperature. Despite the operating difficulties, several periods of steady state operation were achieved, which provided useful data for future testing. TC24 operation afforded the opportunity for testing of various types of technologies, including dry coal feeding with a developmental feeder, the Pressure Decoupled Advanced Coal (PDAC) feeder; evaluating a new hot gas filter element media configuration; and enhancing syngas cleanup with water-gas shift catalysts. During TC24, the PSDF site was also made available for testing of the National Energy Technology Laboratory's fuel cell module and Media Process Technology's hydrogen selective membrane.

Preliminary working paper: satellite power system and lesser developed countries  

DOE Green Energy (OSTI)

The objective of this report is to screen selected countries that, by geographical location, might be appropriate sites for the rectenna system and for which technical, environmental, social, demographic, political, and economic factors make a Satellite Power System (SPS) project appear possible. The study focused on countries that are referred to as Lesser Developed Countries (LDCs). Of 130 countries, sovereignties, and dependencies classified by the United Nations as less developed, thirteen countries were selected for study. The countries in the Americas are Mexico, Colombia, Venezuela, and Brazil. On the African continent, the countries are Algeria, Senegal, Gambia, Zaire, and Kenya. The countries in Asia and Oceania are The People's Republic of China, India, Thailand, and Indonesia. Certain general conclusions can be drawn from this study. Countries that might be able to support or contribute to SPS are the established, major energy exporters. The consumption of countries that export some energy virtually matches production. They may be able to pay for SPS in the years 2000 or 2025, but increased economic development and diversification of exports will need to be implemented first. Finally, those countries that import energy do not have an economic base by which they could support SPS unaided, but require energy. All thirteen nations could benefit from SPS. SPS could prove invaluable to these countries with sensitive economies. The added electrical energy could bolster their economies and provide for increased development so that the nations could suppport or contribute to SPS.

The steady-state self-consistent nonlinear theory for gyrotron with gradually tapered cavity is developed in this paper. A steady-state calculation code including 'cold cavity' and 'hot cavity' is designed. By comparison, a time-domain model analysis of gyrotron operation is also studied by particle-in-cell (PIC). It is found that the tapers of gyrotron have different influences on the modes coupling between the operating mode and the parasitic modes. During the study, an example of 94 GHz gyrotron with pure operating mode TE{sub 03} has been designed. The purity of the operating mode in the optimized cavity is up to -77 dB, and in output waveguide of the cavity is up to -76 dB. At the same time, the beam-wave interaction in the designed cavity has been simulated, too. An output power of 120 kW, corresponding to 41.6% efficiency and an oscillation frequency of 94.099 GHz have been achieved with a 50 kV, 6 A helical electron beam at a guiding magnetic field of 3.5485 T. The results show that the power in spurious modes of the optimized cavity may be kept far below than that of the traditional tapered cavity.

Power Systems Development Facility Gasification Test Run TC11  

Science Conference Proceedings (OSTI)

This report discusses Test Campaign TC11 of the Kellogg Brown & Root, Inc. (KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed gasifier designed to operate as either a combustor or a gasifier in air- or oxygen-blown mode of operation using a particulate control device (PCD). Test run TC11 began on April 7, 2003, with startup of the main air compressor and the lighting of the gasifier start-up burner. The Transport Gasifier operated until April 18, 2003, when a gasifier upset forced the termination of the test run. Over the course of the entire test run, gasifier temperatures varied between 1,650 and 1,800 F at pressures from 160 to 200 psig during air-blown operations and around 135 psig during enriched-air operations. Due to a restriction in the oxygen-fed lower mixing zone (LMZ), the majority of the test run featured air-blown operations.

Power systems development facility. Quarterly report, January 1995--March 1995  

Science Conference Proceedings (OSTI)

The objective of this project is to evaluate hot gas particle control technologies using coal-derived gas streams. This will entail the design, construction, installation, and use of a flexible test facility which can operate under realistic gasification and combustion conditions. The major particulate control device issues to be addressed include the integration of the particulate control devices into coal utilization systems, on-line cleaning techniques, chemical and thermal degradation of components, fatigue or structural failures, blinding, collection efficiency as a function of particle size, and scale-up of particulate control systems to commercial size. The conceptual design of the facility was extended to include a within scope, phased expansion of the existing Hot Gas Cleanup Test Facility Cooperative Agreement to also address systems integration issues of hot particulate removal in advanced coal-based power generation systems. This expansion included the consideration of the following modules at the test facility in addition to the original Transport Reactor gas source and Hot Gas Cleanup Units: (1) Carbonizer/Pressurized Circulating Fluidized Bed Gas Source. (2) Hot Gas Cleanup Units to mate to all gas streams. (3) Combustion Gas Turbine. (4) Fuel Cell and associated gas treatment. This expansion to the Hot Gas Cleanup Test Facility is herein referred to as the Power Systems Development Facility (PSDF). The major emphasis during this reporting period was continuing the detailed design of the facility and integrating the particulate control devices (PCDs) into structural and process designs.

Power Systems Development Facility Gasification Test Run TC07  

SciTech Connect

This report discusses Test Campaign TC07 of the Kellogg Brown & Root, Inc. (KBR) Transport Reactor train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Reactor is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using a particulate control device (PCD). The Transport Reactor was operated as a pressurized gasifier during TC07. Prior to TC07, the Transport Reactor was modified to allow operations as an oxygen-blown gasifier. Test Run TC07 was started on December 11, 2001, and the sand circulation tests (TC07A) were completed on December 14, 2001. The coal-feed tests (TC07B-D) were started on January 17, 2002 and completed on April 5, 2002. Due to operational difficulties with the reactor, the unit was taken offline several times. The reactor temperature was varied between 1,700 and 1,780 F at pressures from 200 to 240 psig. In TC07, 679 hours of solid circulation and 442 hours of coal feed, 398 hours with PRB coal and 44 hours with coal from the Calumet mine, and 33 hours of coke breeze feed were attained. Reactor operations were problematic due to instrumentation problems in the LMZ resulting in much higher than desired operating temperatures in the reactor. Both reactor and PCD operations were stable and the modifications to the lower part of the gasifier performed well while testing the gasifier with PRB coal feed.

Satellite power system. Concept development and evaluation program  

DOE Green Energy (OSTI)

The Reference System description emphasizes technical and operational information required in support of environmental, socioeconomic, and comparative assessment studies. Supporting information has been developed according to a guideline of implementing two 5 GW SPS systems per year for 30 years beginning with an initial operational data of 2000 and with SPS's being added at the rate of two per year (10 GW/year) until 2030. The Reference System concept, which features gallium--aluminum--arsenide (GaAlAs) and silicon solar cell options, is described in detail. The concept utilizes a planar solar array (about 55 km/sup 2/) built on a graphite fiber reinforced thermoplastic structure. The silicon array uses a concentration ratio of one (no concentration), whereas the GaAlAs array uses a concentration ratio of two. A one-kilometer diameter phased array microwave antenna is mounted on one end. The antenna uses klystrons as power amplifiers with slotted waveguides as radiating elements. The satellite is constructed in geosynchronous orbit in a six-month period. The ground receiving stations (rectenna) are completed during the same time period. The other two major components of an SPS program are (1) the construction bases in space and launch and mission control bases on earth and (2) fleets of various transportation vehicles that support the construction and maintenance operations of the satellites. These transportation vehicles include Heavy Lift Launch Vehicles (HLLV), Personnel Launch Vehicles (PLV), Cargo Orbit Transfer Vehicles (COTV), and Personnel Orbit Transfer Vehicles (POTV). The earth launch site chosen is the Kennedy Space Center, pending further study.

Development and testing of improved statistical wind power forecasting methods.  

DOE Green Energy (OSTI)

Wind power forecasting (WPF) provides important inputs to power system operators and electricity market participants. It is therefore not surprising that WPF has attracted increasing interest within the electric power industry. In this report, we document our research on improving statistical WPF algorithms for point, uncertainty, and ramp forecasting. Below, we provide a brief introduction to the research presented in the following chapters. For a detailed overview of the state-of-the-art in wind power forecasting, we refer to [1]. Our related work on the application of WPF in operational decisions is documented in [2]. Point forecasts of wind power are highly dependent on the training criteria used in the statistical algorithms that are used to convert weather forecasts and observational data to a power forecast. In Chapter 2, we explore the application of information theoretic learning (ITL) as opposed to the classical minimum square error (MSE) criterion for point forecasting. In contrast to the MSE criterion, ITL criteria do not assume a Gaussian distribution of the forecasting errors. We investigate to what extent ITL criteria yield better results. In addition, we analyze time-adaptive training algorithms and how they enable WPF algorithms to cope with non-stationary data and, thus, to adapt to new situations without requiring additional offline training of the model. We test the new point forecasting algorithms on two wind farms located in the U.S. Midwest. Although there have been advancements in deterministic WPF, a single-valued forecast cannot provide information on the dispersion of observations around the predicted value. We argue that it is essential to generate, together with (or as an alternative to) point forecasts, a representation of the wind power uncertainty. Wind power uncertainty representation can take the form of probabilistic forecasts (e.g., probability density function, quantiles), risk indices (e.g., prediction risk index) or scenarios (with spatial and/or temporal dependence). Statistical approaches to uncertainty forecasting basically consist of estimating the uncertainty based on observed forecasting errors. Quantile regression (QR) is currently a commonly used approach in uncertainty forecasting. In Chapter 3, we propose new statistical approaches to the uncertainty estimation problem by employing kernel density forecast (KDF) methods. We use two estimators in both offline and time-adaptive modes, namely, the Nadaraya-Watson (NW) and Quantilecopula (QC) estimators. We conduct detailed tests of the new approaches using QR as a benchmark. One of the major issues in wind power generation are sudden and large changes of wind power output over a short period of time, namely ramping events. In Chapter 4, we perform a comparative study of existing definitions and methodologies for ramp forecasting. We also introduce a new probabilistic method for ramp event detection. The method starts with a stochastic algorithm that generates wind power scenarios, which are passed through a high-pass filter for ramp detection and estimation of the likelihood of ramp events to happen. The report is organized as follows: Chapter 2 presents the results of the application of ITL training criteria to deterministic WPF; Chapter 3 reports the study on probabilistic WPF, including new contributions to wind power uncertainty forecasting; Chapter 4 presents a new method to predict and visualize ramp events, comparing it with state-of-the-art methodologies; Chapter 5 briefly summarizes the main findings and contributions of this report.

Development of a photovoltaic power supply for wireless sensor networks.  

DOE Green Energy (OSTI)

This report examines the design process of a photovoltaic (solar) based power supply for wireless sensor networks. Such a system stores the energy produced by an array of photovoltaic cells in a secondary (rechargeable) battery that in turn provides power to the individual node of the sensor network. The goal of such a power supply is to enable a wireless sensor network to have an autonomous operation on the order of years. Ideally, such a system is as small as possible physically while transferring the maximum amount of available solar energy to the load (the node). Within this report, there is first an overview of current solar and battery technologies, including characteristics of different technologies and their impact on overall system design. Second is a general discussion of modeling, predicting, and analyzing the extended operation of a small photovoltaic power supply and setting design parameters. This is followed by results and conclusions from the testing of a few basic systems. Lastly, some advanced concepts that may be considered in order to optimize future systems will be discussed.

Development and Use of the Galileo and Ulysses Power Sources  

SciTech Connect

Paper presented at the 45th Congress of the International Astronautical Federation, October 1994. The Galileo mission to Jupiter and the Ulysses mission to explore the polar regions of the Sun required a new power source: the general-purpose heat source radioisotope thermoelectric generator (GPHS-RTG), the most powerful RTG yet flow. Four flight-qualified GPHS-RTGs were fabricated with one that is being used on Ulysses, two that are being used on Galileo and one that was a common spare (and is now available for the Cassini mission to Saturn). In addition, and Engineering Unit and a Qualification Unit were fabricated to qualify the design for space through rigorous ground tests. This paper summarizes the ground testing and performance predictions showing that the GPHS-RTGs have met and will continue to meet or exceed the performance requirements of the ongoing Galileo and Ulysses missions. There are two copies in the file.

Prospects for the power sector in nine developing countries  

Science Conference Proceedings (OSTI)

Based on information drawn primarily from official planning documents issued by national governments and/or utilities, the authors examined the outlook for the power sector in the year 2000 in nine countries: China, India, Indonesia, Thailand, the Philippines, South Korea, Taiwan, Argentina and Mexico. They found that the implicit rates of average annual growth of installed electric power capacity between 1991 and 2001 range from a low of 3.3% per year in Argentina to a high of 13.2% per year in Indonesia. In absolute terms, China and India account for the vast majority of the growth. The plans call for a shift in the generating mix towards coal in six of the countries, and continued strong reliance on coal in China and India. The use of natural gas is expected to increase substantially in a number of the countries. The historic movement away from oil continues, although some countries are maintaining dual-fuel capabilities. Plans call for considerable growth of nuclear power in South Korea and China and modest increases in India and Taiwan. The feasibility of the official plans varies among the countries. Lack of public capital is leading towards greater reliance on private sector participation in power projects in many of the countries. Environmental issues are becoming a more significant constraint than in the past, particularly in the case of large-scale hydropower projects. The financial and environmental constraints are leading to a rising interest in methods of improving the efficiency of electricity supply and end use. The scale of such activities is growing in most of the study countries.

Development of High Average Power Lasers for the Photon Collider  

SciTech Connect

The laser and optics system for the photon collider seeks to minimize the required laser power by using an optical stacking cavity to recirculate the laser light. An enhancement of between 300 to 400 is desired. In order to achieve this the laser pulses which drive the cavity must precisely match the phase of the pulse circulating within the cavity. We report on simulations of the performance of a stacking cavity to various variations of the drive laser in order to specify the required tolerances of the laser system.

Development of a high-power lithium-ion battery.  

DOE Green Energy (OSTI)

Safety is a key concern for a high-power energy storage system such as will be required in a hybrid vehicle. Present lithium-ion technology, which uses a carbon/graphite negative electrode, lacks inherent safety for two main reasons: (1) carbon/graphite intercalates lithium at near lithium potential, and (2) there is no end-of-charge indicator in the voltage profile that can signal the onset of catastrophic oxygen evolution from the cathode (LiCoO{sub 2}). Our approach to solving these safety/life problems is to replace the graphite/carbon negative electrode with an electrode that exhibits stronger two-phase behavior further away from lithium potential, such as Li{sub 4}Ti{sub 5}O{sub 12}. Cycle-life and pulse-power capability data are presented in accordance with the Partnership for a New Generation of Vehicles (PNGV) test procedures, as well as a full-scale design based on a spreadsheet model.

Factors driving wind power development in the United States  

SciTech Connect

In the United States, there has been substantial recent growth in wind energy generating capacity, with growth averaging 24 percent annually during the past five years. About 1,700 MW of wind energy capacity was installed in 2001, while another 410 MW became operational in 2002. This year (2003) shows promise of significant growth with more than 1,500 MW planned. With this growth, an increasing number of states are experiencing investment in wind energy projects. Wind installations currently exist in about half of all U.S. states. This paper explores the key factors at play in the states that have achieved a substantial amount of wind energy investment. Some of the factors that are examined include policy drivers, such as renewable portfolio standards (RPS), federal and state financial incentives, and integrated resource planning; as well as market drivers, such as consumer demand for green power, natural gas price volatility, and wholesale market rules.

Development of Improved Burnable Poisons for Commercial Nuclear Power Reactors  

Science Conference Proceedings (OSTI)

Burnable poisons are used in nuclear reactors to produce a more level distribution of power in the reactor core and to reduce to necessity for a large control system. An ideal burnable poison would burn at the same rate as the fuel. In this study, separation of neutron-absorbing isotopes was investigated in order to eliminate isotopes that remain as absorbers at the end of fuel life, thus reducing useful fuel life. The isotopes Gd-157, Dy-164, and Er-167 were found to have desirable properties. These isotopes were separated from naturally occurring elements by means of plasma separation to evaluate feasibility and cost. It was found that pure Gd-157 could save approximately $6 million at the end of four years. However, the cost of separation, using the existing facility, made separation cost- ineffective. Using a magnet with three times the field strength is expected to reduce the cost by a factor of ten, making isotopically separated burnable poisons a favorable method of increasing fuel life in commercial reactors, in particular Generation-IV reactors. The project also investigated various burnable poison configurations, and studied incorporation of metallic burnable poisons into fuel cladding.

Economic analysis of nuclear power reactor dissemination to less developed nations with implications for nuclear proliferation  

SciTech Connect

An economic model is applied to the transfer of nuclear-power reactors from industrialized nations to the less developed nations. The model includes demand and supply factors and predicts the success of US nonproliferation positions and policies. It is concluded that economic forces dominate the transfer of power reactors to less developed nations. Our study shows that attempts to either restrict or promote the spread of nuclear-power technology by ignoring natural economic incentives would have only limited effect. If US policy is too restrictive, less developed nations will seek other suppliers and thereby lower US Influence substantially. Allowing less developed nations to develop nuclear-power technology as dictated by economic forces will result in a modest rate of transfer that should comply with nuclear-proliferation objectives.

A Comparative Analysis of Community Wind Power DevelopmentModels  

DOE Green Energy (OSTI)

For years, farmers in the United States have looked with envy on their European counterparts ability to profitably farm the wind through ownership of distributed, utility-scale wind projects. Only within the past few years, however, has farmer- or community-owned windpower development become a reality in the United States. The primary hurdle to this type of development in the United States has been devising and implementing suitable business and legal structures that enable such projects to take advantage of tax-based federal incentives for windpower. This article discusses the limitations of such incentives in supporting farmer- or community-owned wind projects, describes four ownership structures that potentially overcome such limitations, and finally conducts comparative financial analysis on those four structures, using as an example a hypothetical 1.5 MW farmer-owned project located in the state of Oregon. We find that material differences in the competitiveness of each structure do exist, but that choosing the best structure for a given project will largely depend on the conditions at hand; e.g., the ability of the farmer(s) to utilize tax credits, preference for individual versus cooperative ownership, and the state and utility service territory in which the project will be located.

SciTech Connect

The reactor design which forms the base for the current economic status of D/sub 2/O-moderated reactors was estimated from developments in several reactor programs. However, since a heavy water-moderated reactor was not operated on natural U fuel at power reactor conditions, considerable improvement from this current status can be foreseen. A summary of improvements is presented concerning the concept which would result solely from operation of succeeding generation plants without a parallel development program, and improvements which would result from the successful completion of the development program as presented. One plant size was used in the evaluation of plant potential, with a 300 Mw/sub e/ nominal rating. The boiling D/sub 2/O-cooled, pressure tube direct cycle plant design was used. The current development program is outlined; this work includes several items leading to the long-range development of the concept. (auth)

Ocean thermal energy conversion (OTEC) power system development. Preliminary design report, Appendices, Part 1 (Final)  

DOE Green Energy (OSTI)

The objective of this project is the development of a preliminary design for a full-sized, closed cycle, ammonia power system module for the 100 MWe OTEC demonstration plant. In turn, this demonstration plant is to demonstrate, by 1984, the operation and performance of an Ocean Thermal Power Plant having sufficiently advanced heat exchanger design to project economic viability for commercial utilization in the late 1980's and beyond. Included in this power system development are the preliminary designs for a proof-of-concept pilot plant and test article heat exchangers which are scaled in such a manner as to support a logically sequential, relatively low-cost development of the full-scale power system module. The conceptual designs are presented for the demonstration plant power module, the proof-of-concept pilot plant, and for a pair of test article heat exchangers. Costs associated with the design, development, fabrication, checkout, delivery, installation, and operation are included. The accompanying design and producibilty studies on the full-scale power system module project the performance/economics for the commercial plant. This section of the report contains appendices on the developed computer models, water system dynamic studies, miscellaneous performance analysis, materials and processes, detailed equipment lists, turbine design studies, tube cleaner design, ammonia leak detection, and heat exchanger design supporting data.

100kW Energy Transfer Multiplexer Power Converter Prototype Development Project  

DOE Green Energy (OSTI)

Project Final Report for "100kW Energy Transfer Multiplexer Power Converter Prototype Development Project" prepared under DOE grant number DE-FG36-03GO13138. This project relates to the further development and prototype construction/evaluation for the Energy Transfer Multiplexer (ETM) power converter topology concept. The ETM uses a series resonant link to transfer energy from any phase of a multiphase input to any phase of a multiphase output, converting any input voltage and frequency to any output voltage and frequency. The basic form of the ETM converter consists of an eight (8)-switch matrix (six phase power switches and two ground power switches) and a series L-C resonant circuit. Electronic control of the switches allows energy to be transferred in the proper amount from any phase to any other phase. Depending upon the final circuit application, the switches may be either SCRs or IGBTs. The inherent characteristics of the ETM converter include the following: Power processing in either direction (bidirectional); Large voltage gain without the need of low frequency magnetics; High efficiency independent of output load and frequency; Wide bandwidth with fast transient response and; Operation as a current source. The ETM is able to synthesize true sinusoidal waveforms with low harmonic distortions. For a low power PM wind generation system, the ETM has the following characteristics and advantages: It provides voltage gain without the need of low frequency magnetics (DC inductors) and; It has constant high efficiency independent of the load. The ETM converter can be implemented into a PM wind power system with smaller size, reduced weight and lower cost. As a result of our analyses, the ETM offers wind power generation technology for the reduction of the cost and size as well as the increase in performance of low power, low wind speed power generation. This project is the further theoretical/analytical exploration of the ETM converter concept in relationship to PM wind power generator applications in the 100kW and under power range. The theoretical/analytical and bench scale work focuses on simplifying the basic ETM converter topology (in terms of parts count and complexity) for the specific application of the low power PM system. The project goals and objectives were for Spellman HV will develop a 100kW prototype ETM power converter based on paralleled lower ratings converters. The proposed configuration of this prototype is a 100kW rated converter comprised of four (4) 34kW rated modules connected in parallel (the fourth converter is included to demonstrate N+1 fault tolerance). This approach is more viable as there is lower technological risk involved in developing a 34kW-rated converter than a single 100kW unit. The modular system approach should have a lower deployment and service cost over a single unit system, because of the economics of scale (smaller units at a higher volume means lower manufacturing cost) and because of improved serviceability (a non-redundant power system with one failed module will still operate at a lower power level). There is also the added benefit that greater commercial application and acceptance should be achieved by having a modular system available in which fault tolerance (N+1 or 2N) is a feature. This modular approach would allow the output power to be increased by adding more paralleled converters. Thus, the maximum output power of the overall power system is a function of the interconnection medium (the hot swap connection subsystem), rather than the ratings of a single module. The project was implemented with Spellman HV acting as the program management and production assembly and test facility; The Baker Company acting as a technical consultant and resource when required; and dtm Associates acting as the design/development resource for the hardware development of the 100kW ETM converter prototype.

Economic Development Impacts of Wind Power--Case Studies Fact Sheet  

DOE Green Energy (OSTI)

OAK-B135 Interest in wind power development is growing as a means of expanding local economies. Such development holds promise as a provider of short-term employment during facility construction and long-term employment from ongoing facility operation and maintenance (O&M). It may also add to the supply of electric power in the area and support some expansion of the local economy through ripple effects resulting from initial increases in jobs and income. These ripple effects stem from subsequent expenditures for goods and services made possible by first-round income from the development, and are expressed in terms of a multiplier. If the local economy offers a wide range of goods and services the resulting multiplier can be substantial--as much as three or four. If not, then much of the initial income will leave the local economy to buy goods and services from elsewhere. Loss of initial income to other locales is referred to as a leakage. While there is a growing body of information about the local impacts of wind power, the economic impacts from existing wind power developments have not been thoroughly and consistently analyzed. Northwest Economic Associates, under contract to the National Wind Coordinating Committee (NWCC), conducted a study and produced a report entitled ''Assessing the Economic Development Impacts of Wind Power.'' The primary objective of the study was to provide examples of appropriate analyses and documentation of economic impacts from wind power development, using case studies of three existing projects in the United States. The findings from the case studies are summarized here; more detail is available in the report, available at NWCC's website http://www.nationalwind.org/. It should be noted that specific results presented apply only to the respective locales studied and are not meant to be representative of wind power in general. However, qualitative findings, discussed below, are likely to be replicated in most areas where wind development occurs.

Power system development: Ocean Thermal Energy Conversion (OTEC). Preliminary design report: appendices, Part 2 (Final)  

DOE Green Energy (OSTI)

The objective of this project is the development of a preliminary design for a full-sized, closed cycle, ammonia power system module for the 100 MWe OTEC demonstration plant. In turn, this demonstration plant is to demonstrate, by 1984, the operation and performance of an Ocean Thermal Power Plant having sufficiently advanced heat exchanger design to project economic viability for commercial utilization in the late 1980's and beyond. Included in this power system development are the preliminary designs for a proof-of-concept pilot plant and test article heat exchangers which are scaled in such a manner as to support a logically sequential, relatively low-cost development of the full-scale power system module. The conceptual designs are presented for the demonstration plant power module, the proof-of-concept pilot plant, and for a pair of test article heat exchangers. Costs associated with the design, development, fabrication, checkout, delivery, installation, and operation are included. The accompanying design and producibilty studies on the full-scale power system module project the performance/economics for the commercial plant. This section of the report contains appendices on the electrical system, instrumentation and control, ammonia pump evaluation study, ammonia and nitrogen support subsystems, piping and support design calculations, and plant availability.

Biomass power for rural development. Technical progress report, Phase 2, July 1--September 30, 1998  

DOE Green Energy (OSTI)

The project undertaken by the Salix Consortium is a multi-phased, multi-partner endeavor. Phase 1 focused on initial development and testing of the technology and forging the necessary agreements to demonstrate commercial willow production. The Phase 1 objectives have been successfully completed: preparing final design plans for two utility pulverized coal boiler for 20 MW of biopower capacity; developing fuel supply plans for the project with a goal of establishing 365 ha (900 ac) of willow; obtaining power production commitments from the power companies for Phase 2; obtaining construction and environmental permits; and developing an experimental strategy for crop production and power generation improvements needed to assure commercial success. The R and D effort also addresses environmental issues pertaining to introduction of the willow energy system. Beyond those Phase 1 requirements, the Consortium has already successfully demonstrated cofiring at Greenidge Station and has initiated development of the required nursery capacity for acreage scale-up. In Phase 2 every aspect of willow production and power generation from willow biomass will be demonstrated. The ultimate objective of Phase 2 is to transition the work performed under the Biomass Power for Rural Development project into a thriving, self-supported energy crop enterprise.

Ocean Thermal Energy Conversion power system development. Phase I. Final report  

DOE Green Energy (OSTI)

This report covers the conceptual and preliminary design of closed-cycle, ammonia, ocean thermal energy conversion power plants by Westinghouse Electric Corporation. Preliminary designs for evaporator and condenser test articles (0.13 MWe size) and a 10 MWe modular experiment power system are described. Conceptual designs for 50 MWe power systems, and 100 MWe power plants are also descirbed. Design and cost algorithms were developed, and an optimized power system design at the 50 MWe size was completed. This design was modeled very closely in the test articles and in the 10 MWe Modular Application. Major component and auxiliary system design, materials, biofouling, control response, availability, safety and cost aspects are developed with the greatest emphasis on the 10 MWe Modular Application Power System. It is concluded that all power plant subsystems are state-of-practice and require design verification only, rather than continued research. A complete test program, which verifies the mechanical reliability as well as thermal performance, is recommended and described.

Particulate Control Device (PCD) Testing at the Power Systems Development Facility, Wilsonville, Alabama  

Science Conference Proceedings (OSTI)

One of the U.S. Department of Energy`s (DOE`s) objectives overseen by the Morgantown Energy Technology Center (METC) is to test systems and components for advanced coal-based power generation systems, including integrated gasification combined cycle (IGCC), pressurized fluidized-bed combustion (PFBC), and integrated gasification/fuel cell (IGFC) systems. Stringent particulate requirements for fuel gas for both combustion turbines and fuel cells that are integral to these systems. Particulates erode and chemically attack the blade surfaces in turbines, and cause blinding of the electrodes in fuel cells. Filtration of the hot, high-pressure, gasified coal is required to protect these units. Filtration can be accomplished by first cooling the gas, but the system efficiency is reduced. High-temperature, high-pressure, particulate control devices (PCDs) need to be developed to achieve high efficiency and to extend the lifetime of downstream components to acceptable levels. Demonstration of practical high-temperature PCDs is crucial to the evolution of advanced, high-efficiency, coal-based power generation systems. The intent at the Power Systems Development Facility (PSDF) is to establish a flexible test facility that can be used to (1) develop advanced power system components, such as high-temperature, high-pressure PCDs; (2) evaluate advanced power system configurations and (3) assess the integration and control issues of these advanced power systems.

The methodology used for that study is summarized here in order to provide guidance for future studies of the economic impacts of other wind power developments. The methodology used in the NEA study was specifically designed for these particular case study areas; however, it can be generally applied to other areas. Significant differences in local economic conditions and the amount of goods and services that are purchased locally as opposed to imported from outside the will strongly influence results obtained.

The future of nuclear energy: A perspective on nuclear power development  

Science Conference Proceedings (OSTI)

The author begins by discussing the history of nuclear power development in the US. He discusses the challenges for nuclear power such as the proliferation of weapons material, waste management, economics, and safety. He then discusses the future for nuclear power, specifically advanced reactor development. People can all be thankful for nuclear power, for it may well be essential to the long term survival of civilization. Within the seeds of its potential for great good, are also the seeds for great harm. People must ensure that it is applied for great good. What is not in question is whether people can live without it, they cannot. United States leadership is crucial in determining how this technology is developed and applied. The size and capability of the United States technical community is decreasing, a trend that cannot be allowed to continue. It is the author's belief that in the future, the need, the vision and the confidence in nuclear power will be restored, but only if the US addresses the immediate challenges. It is a national challenge worthy of the best people this nation has to offer.

Ocean Thermal Energy Conversion power system development. Phase I: preliminary design. Final report  

DOE Green Energy (OSTI)

Westinghouse has completed the Preliminary Design Phase for the Power System Development of the Ocean Thermal Energy Conversion (OTEC) Demonstration Plant project. This study included the development of a preliminary design for a Modular Application scaled power system (10MWe) and Heat Exchanger Test Articles, both based on the concept developed in the Conceptual Design Phase. The results of this study were used to improve the baseline design of the 50MWe module for the Commercial Size Power System, which was recommended for the demonstration plant by the conceptual design study. The 50MWe module was selected since it has the lowest cost, and since its size convincingly demonstrates that future economically viable commercial plants, having reliable operation with credible anticipated costs, are possible. Additional optimization studies on the size of the power system plus hull continue to identify 50MWe as the preferred minimum cost configuration. This study was limited to a closed cycle ammonia power system module, using a seawater temperature difference of 40/sup 0/F, and a surface platform/ship reference hull. This volume describes system operation, a complete test program to verify mechanical reliability and thermal performance, fabrication and installation operations, and a cost analysis. (WHK)

Innovation Approaches to Development and Ground Testing of Advanced Bimodal Space Power and Propulsion Systems  

DOE Green Energy (OSTI)

The last major development effort for nuclear power and propulsion systems ended in 1993. Currently, there is not an initiative at either the National Aeronautical and Space Administration (NASA) or the U.S. Department of Energy (DOE) that requires the development of new nuclear power and propulsion systems. Studies continue to show nuclear technology as a strong technical candidate to lead the way toward human exploration of adjacent planets or provide power for deep space missions, particularly a 15,000 lbf bimodal nuclear system with 115 kW power capability. The development of nuclear technology for space applications would require technology development in some areas and a major flight qualification program. The last major ground test facility considered for nuclear propulsion qualification was the U.S. Air Force/DOE Space Nuclear Thermal Propulsion Project. Seven years have passed since that effort, and the questions remain the same, how to qualify nuclear power and propulsion systems for future space flight. It can be reasonably assumed that much of the nuclear testing required to qualify a nuclear system for space application will be performed at DOE facilities as demonstrated by the Nuclear Rocket Engine Reactor Experiment (NERVA) and Space Nuclear Thermal Propulsion (SNTP) programs. The nuclear infrastructure to support testing in this country is aging and getting smaller, though facilities still exist to support many of the technology development needs. By renewing efforts, an innovative approach to qualifying these systems through the use of existing facilities either in the U.S. (DOE's Advance Test Reactor, High Flux Irradiation Facility and the Contained Test Facility) or overseas should be possible.

Sweet Lake Geopressured-geothermal Project, Magma Gulf-Technadril/DOE Amoco Fee. Volume II. Surface installations reservoir testing. Annual report, February 28, 1981-February 10, 1982  

DOE Green Energy (OSTI)

The Magma Gulf-Technadril/Department of Energy Amoco Fee No. 1 (production) and salt water disposal wells were drilled in the period from August, 1980 to February 1981. Surface facilities were designed and constructed during March-June 1981. Flow testing began in June 1981 and continued until February, 1982. The Miogypsinoides interval contains seven discrete sands in the test well. These sands have been numbered 1 to 7, beginning at the top of the sequence. Data from wireline logs and core samples suggested that the first zone to be perforated should be Sand 5. Because of its high porosity and permeability, Sand 5 was thought to contain almost 50% of the total hydraulic capacity of the well. Flow testing of Sand 5 was performed in three stages, each of which is fully described in this report. Phase I was designed as an initial clean-up flow and a reservoir confirmation test. Phase II consisted of the reservoir limit determination test and lasted 17 days. Boundaries were confirmed which suggest that the Sweet Lake reservoir is fairly narrow, with boundaries on three sides, but is open in one direction with no closure for at least 4-1/4 miles. These boundaries approximate the shape of the graben in which the test well was drilled, but may or may not be directly related to the major faults forming the graben. Phase III testing was planned to be a long-term test at commercial design rates. Although Sand 5 alone would not support such rates, long-term production was demonstrated. Additional research not supported by DOE funding was also performed during the period covered by this report. This research, consisting of mud logging, micropaleontology, organic geochemistry, core analysis, and rock mechanics, is summarized in this report.

Geopressured-geothermal test of the EDNA Delcambre No. 1 well, Tigre Lagoon Field, Vermilion Parish, Louisiana: analysis of water an dissolved natural gas. Final report  

DOE Green Energy (OSTI)

The Edna Delcambre et al. No. 1 gas well, shut-in since June 1975, was made available for the project. Two geopressured sand-bed aquifers were tested: sand No. 3 at a depth of 12,900 feet and sand No. 1 at a depth of 12,600 feet. Each aquifer was subjected to flow tests which lasted approximately three weeks in each case. Water samples were obtained during flow testing of the two geopressured aquifers. The water contained 11.3 to 13.3% dissolved solids. Several radioactive species were measured. Radium-226 was found to be approximately 10 times more concentrated than the average amount observed in surface waters. No appreciable amount of heavy metals was detected. Recombination studies at bottom-hole conditions indicate the solubility of natural gas per barrel of water to be about 24 SCF. The methane content was 93 to 95%, and the gas had a heating value in the range of 1020 to 1070 Btu/cu.ft. During the flow tests, the gas/water ratio at the well-head was observed to be 45 to 88 SCF/Bbl water produced. (MHR)

Definition of the development program for an MHD advanced power train. Volume I. Final report  

DOE Green Energy (OSTI)

The MHD power train designs in the APT program are all aimed at early commercial use of MHD, and thus not representative of more advanced and mature MHD power systems. Accordingly, the power train design approaches in Task 2 as well as the MHD power plant designs in Task 1 were selected for early use and based on present status and experience gained in MHD technology development. Naturally, significant improvements and advancements of MHD technology can be expected after its commercial introduction like that experienced for any other new technology. The information developed in Task 1 of the APT program provided basic information for use in the subsequent task activities reported on here. One important conclusion from the work conducted in Task 1 was the selection of supersonic channel operation at a peak magnetic field strength of about 4.5 Tesla for first commercial use. An important result from the continued MHD generator performance studies conducted as part of Task 2 and reported on here was that the supersonic channel design also offers efficient operation at part load. The MHD generator channel operation at part load was found to shift to transonic and subsonic operation to maintain high efficiency as load decreases. Furthermore, the performance sensitivity analyses in Task 2 substantiated that net MHD power output (MHD generator gross power minus compressor power for oxygen production and compression of the oxygen-enriched combustion air to peak cycle pressure) is reached at the oxidizer/fuel equivalence ratio of 0.9 initially selected in Task 1, although the highest flame temperature and electrical conductivity of the gases produced in the combustor occur at a lower stoichiometry. 48 figs., 41 tabs.

Development of hydrogeological modelling approaches for assessment of consequences of hazardous accidents at nuclear power plants  

SciTech Connect

This paper introduces some modeling approaches for predicting the influence of hazardous accidents at nuclear reactors on groundwater quality. Possible pathways for radioactive releases from nuclear power plants were considered to conceptualize boundary conditions for solving the subsurface radionuclides transport problems. Some approaches to incorporate physical-and-chemical interactions into transport simulators have been developed. The hydrogeological forecasts were based on numerical and semi-analytical scale-dependent models. They have been applied to assess the possible impact of the nuclear power plants designed in Russia on groundwater reservoirs.

Electric Power Infrastructure Reliability and Security (EPIRS) Reseach and Development Initiative  

DOE Green Energy (OSTI)

Power systems have become increasingly complex and face unprecedented challenges posed by population growth, climate change, national security issues, foreign energy dependence and an aging power infrastructure. Increased demand combined with increased economic and environmental constraints is forcing state, regional and national power grids to expand supply without the large safety and stability margins in generation and transmission capacity that have been the rule in the past. Deregulation, distributed generation, natural and man-made catastrophes and other causes serve to further challenge and complicate management of the electric power grid. To meet the challenges of the 21st century while also maintaining system reliability, the electric power grid must effectively integrate new and advanced technologies both in the actual equipment for energy conversion, transfer and use, and in the command, control, and communication systems by which effective and efficient operation of the system is orchestrated - in essence, the 'smart grid'. This evolution calls for advances in development, integration, analysis, and deployment approaches that ultimately seek to take into account, every step of the way, the dynamic behavior of the system, capturing critical effects due to interdependencies and interaction. This approach is necessary to better mitigate the risk of blackouts and other disruptions and to improve the flexibility and capacity of the grid. Building on prior Navy and Department of Energy investments in infrastructure and resources for electric power systems research, testing, modeling, and simulation at the Florida State University (FSU) Center for Advanced Power Systems (CAPS), this project has continued an initiative aimed at assuring reliable and secure grid operation through a more complete understanding and characterization of some of the key technologies that will be important in a modern electric system, while also fulfilling an education and outreach mission to provide future energy workforce talent and support the electric system stakeholder community. Building upon and extending portions of that research effort, this project has been focused in the following areas: (1) Building high-fidelity integrated power and controls hardware-in-the-loop research and development testbed capabilities (Figure 1). (2) Distributed Energy Resources Integration - (a) Testing Requirements and Methods for Fault Current Limiters, (b) Contributions to the Development of IEEE 1547.7, (c) Analysis of a STATCOM Application for Wind Resource Integration, (d) Development of a Grid-Interactive Inverter with Energy Storage Elements, (e) Simulation-Assisted Advancement of Microgrid Understanding and Applications; (3) Availability of High-Fidelity Dynamic Simulation Tools for Grid Disturbance Investigations; (4) HTS Material Characterization - (a) AC Loss Studies on High Temperature Superconductors, (b) Local Identification of Current-Limiting Mechanisms in Coated Conductors; (5) Cryogenic Dielectric Research; and (6) Workshops, education, and outreach.

Research and Development for Novel Thermal Energy Storage Systems (TES) for Concentrating Solar Power (CSP)  

SciTech Connect

The overall objective was to develop innovative heat transfer devices and methodologies for novel thermal energy storage systems for concentrating solar power generation involving phase change materials (PCMs). Specific objectives included embedding thermosyphons and/or heat pipes (TS/HPs) within appropriate phase change materials to significantly reduce thermal resistances within the thermal energy storage system of a large-scale concentrating solar power plant and, in turn, improve performance of the plant. Experimental, system level and detailed comprehensive modeling approaches were taken to investigate the effect of adding TS/HPs on the performance of latent heat thermal energy storage (LHTES) systems.

Making european-style community wind power development work in theUnited States  

DOE Green Energy (OSTI)

Once primarily a European phenomenon, community wind power development--defined here as one or more locally owned, utility-scale wind turbines interconnected on either the customer or utility side of the meter--is gaining a foothold in an increasing number of states throughout the United States. This article describes the various policies and incentives that Minnesota, Wisconsin, Iowa, and Massachusetts are using to support community wind power development, and how state and federal support influences the types of projects and ownership structures that are being developed. Experience in these states demonstrates that, with an array of incentives and creative financing schemes targeted at community-scale projects, there are opportunities to make community wind work in the United States.

Thermoelectric Alloys and Devices for Radioisotope Space Power Systems: State of the Art and Current Developments  

SciTech Connect

Lead telluride and silicon germanium type alloys have served over the past several decades as the preferred thermoelectric conversion materials for U. S. radioisotope thermoelectric generator (RTG) power systems for planetary deep space exploration missions. The Pioneer missions to Jupiter and Jupiter/Saturn and the Viking Mars Lander missions employed TAGS-2N (lead and germanium telluride derivatives) power conversion devices. Since 1976, silicon germanium (SiGe) alloys, incorporated into the unicouple device, have evolved as the thermoelectric materials of choice for U. S. RTG powered space missions. These include the U. S. Air Force Lincoln Experimental Satellites 8 & 9 for communications, in 1976, followed in 1977 by the National Aeronautics and Space Administration Voyager 1 and 2 planetary missions. In 1989, advanced SiGe RTGs were used to power the Galileo exploration of Jupiter and, in 1990, will be used to power the Ulysses investigation of the Sun. In addition, SiGe technology has been chosen to provide RTG power for the 1995 Comet Rendezvous and Asteroid Flyby mission and the 1996 Cassini Saturn orbiter mission. Summaries of the flight performance data for these systems are presented.; Current U. S. Department of Energy thermoelectric development activities include (1) the development of conversion devices based on hi-density, close packed couple arrays and (2) the development of improved performance silicon germanium type thermoelectric materials. The silicon germanium type "multicouple", being developed in conjunction with the Modular RTG program, is discussed in a companion paper. A lead telluride type close-packed module, discussed herein, offers the promise of withstanding high velocity impacts and, thus, is a candidate for a Mars Penetrator application.; Recent projects sponsored by the U. S. Department of Energy, including the Improved Thermoelectric Materials and Modular Radioisotope Thermoelectric Generator programs, have shown that improvements in silicon germanium thermoelectric energy conversion capabilities of at least 50 percent can be achieved by tailoring the characteristics of the silicon germanium alloy materials and devices. This paper compares the properties and characteristics of the SiGe alloys now being developed with those used in the operational space power system.

Report on Performance of Prototype Dynatronix Power Supplies Developed Under a Phase I DOE SBIR  

SciTech Connect

The purpose of this study is to evaluate the prototype power supplies fabricated by Dynatronix, Inc. This project supports the advancement of electroforming capabilities to produce ultra-high purity copper. Ultra-high purity copper is an essential material used for a range of current and future fundamental nuclear physics programs such as the MAJORANA DEMONSTRATOR. The Mach 30 power supplies are a new design built to the specifications from the requirements of Pacific Northwest National Laboratory (PNNL) with regard to timing, voltage, current output, and the required tolerances. The parameters used in these tests were developed empirically over a number of years based on a combination of thermodynamic and kinetics of the electroplating process. The power supplies were operated in a typical cleanroom environment for the production electroforming at PNNL. The units that were received by PNNL in July, 2010 have performed satisfactorily and have demonstrated short term durability.

Power electronics devices hold substantial promise for making distributed energy applications more efficient and cost effective. This project is motivated towards developing and testing inverters that will allow distributed energy systems to provide ancillary services such as voltage and VAR regulation, and increased grid reliability by seamlessly transitioning between grid-tied and stand-alone operation modes. The objectives of this project are to identify system integration and optimization issues and technologies and to provide solutions through research, analysis, and testing of power electronic interfaces for distributed energy applications that are cost-competitive and have substantially faster response times than conventional technologies. In addition, the testing of power electronics interfaces will develop a technical basis for performance assessment for distributed energy systems, subsystems, and components that will finally create a foundation for standardized measurements and test procedures. The ultimate goal for this research is to advance the potential benefits of distributed energy to provide ancillary services, enhance power system reliability, and allow customer choice.

Development of static and simulation programs for voltage stability studies of bulk power system  

SciTech Connect

In the analysis and evaluation of voltage stability, it is necessary to accurately identify the stability margin at each load point under specific system configuration or power balance condition. Voltage stability margin can be basically identified by the multi-solution load flow calculation method. When predicted by this static analysis that voltage instability may occur, time domain simulation will be required which includes the models of various control equipments related with system voltage profile. To deal with this, the following two analytical computer codes shown below were developed. (1) Voltage stability static analysis computer code employing a new load flow calculation method. (2) Time domain long term simulation computer code for voltage stability. These computer codes can also calculate the voltage stability index at each load point which is based on the margin to the stability power limit at each load point. The practicality of these codes developed were verified by applying to the IEEE-118 test system.

Science Conference Proceedings (OSTI)

The objective of this project is to research and develop a thermal energy storage system (operating range 3000C ���¢�������� 450 0C ) based on encapsulated phase change materials (PCM) that can meet the utility-scale base-load concentrated solar power plant requirements at much lower system costs compared to the existing thermal energy storage (TES) concepts. The major focus of this program is to develop suitable encapsulation methods for existing low-cost phase change materials that would provide a cost effective and reliable solution for thermal energy storage to be integrated in solar thermal power plants. This project proposes a TES system concept that will allow for an increase of the capacity factor of the present CSP technologies to 75% or greater and reduce the cost to less than $20/kWht.

The objectives of the Power Systems Development Facility (PSDF) are to develop advanced coal-fired power generation technologies through the testing and evaluation of hot gas cleanup systems and other major components at the pilot scale and to assess and demonstrate the performance of the components in an integrated mode of operation and at a component size easily scaled to commercial systems. This will entail the design, construction, installation, and use of a flexible test facility, which can operate under realistic gasification and combustion conditions. The major particulate control device issues to be addressed include the integration of the particulate control devices (PCDS) into coal utilization systems, on-line cleaning techniques, chemical and thermal degradation of components, fatigue or structural failures, blinding, collection efficiency as a function of particle size and scale-up of particulate control systems to commercial size. The status of the Pressurized Fluidized Bed Combustor at the PSDF is reported here.

Producer gas power plants can cut the oil bills of the developing countries  

SciTech Connect

As a power-generation fuel substitute in developing countries, producer gas from coal, biomass, or waste could reduce oil-import bills while assuring a steady fuel supply. An international working group formed at the Royal Swedish Academy of Sciences is assisting developing countries in setting up simple producer-gas plants consisting of a downdraft gasifier, cyclone, filter, and cooler. Sweden gained expertise in this technology during World War II and now manufactures much of the equipment needed for producer-gas facilities. Depending on oil price, a dual-fuel power plant (15% diesel oil, 85% producer gas) could compete economically with a diesel-only plant, assuming extra labor requirements of 20 min/hr of operation for the gas-fired facility.

Biomass power for rural development. Technical progress report, May 1, 1996--December 31, 1996  

DOE Green Energy (OSTI)

Developing commercial energy crops for power generation by the year 2000 is the focus of the DOE/USDA sponsored Biomass Power for Rural Development project. The New York based Salix Consortium project is a multi-partner endeavor, implemented in three stages. Phase-I, Final Design and Project Development, will conclude with the preparation of construction and/or operating permits, feedstock production plans, and contracts ready for signature. Field trials of willow (Salix) have been initiated at several locations in New York (Tully, Lockport, King Ferry, La Facette, Massena, and Himrod) and co-firing tests are underway at Greenidge Station (NYSEG). Phase-II of the project will focus on scale-up of willow crop acreage, construction of co-firing facilities at Dunkirk Station (NMPC), and final modifications for Greenidge Station. There will be testing of the energy crop as part of the gasification trials expected to occur at BED`s McNeill power station and potentially at one of GPU`s facilities. Phase-III will represent full-scale commercialization of the energy crop and power generation on a sustainable basis. Willow has been selected as the energy crop of choice for many reasons. Willow is well suited to the climate of the Northeastern United States, and initial field trials have demonstrated that the yields required for the success of the project are obtainable. Like other energy crops, willow has rural development benefits and could serve to diversify local crop production, provide new sources of income for participating growers, and create new jobs. Willow could be used to put a large base of idle acreage back into crop production. Additionally, the willow coppicing system integrates well with current farm operations and utilizes agricultural practices that are already familiar to farmers.

Environmental assessment for the satellite power system concept development and evaluation program: atmospheric effects  

DOE Green Energy (OSTI)

The US Department of Energy (DOE) has undertaken a preliminary, three-year program to investigate the impacts of the construction and operation of a satellite power system, of unprecedented scale. The Department of Energy's program, titled The Concept Development and Evaluation Program, focused its investigations on a Reference System description that calls for the use of either silicon (Si) or gallium aluminum-arsenide (GaAlAs) photovoltaic cells on 60 satellites to be constructed in GEO over a 30-yr period. Rectennas would be constructed on the ground to receive microwave energy from the satellites. Each satellite-rectenna pair is designed to produce 5 GW of power on an essentially continuous basis for use as a baseload power source for an electric power distribution system. The environmental assessment part of the program was divided into five interdependent task areas. The present document constitutes the final technical report on one of the five task areas, the Assessment of the Atmospheric Effects, and as such presents an in-depth summary of work performed during the assessment program. The issues associated with SPS activities in the troposphere are examined. These include tropospheric weather modification related to rectenna operations and rocket launches, and air quality impacts related to rocketlaunch ground clouds. Then progressing upward through the various levels of the atmosphere, the principal middle and upper atmospheric effects associated with rocket effluents are analyzed. Finally, all of the potential SPS atmospheric effects are summarized.

Environmental Impacts of Wind Power Development on the Population Biology of Greater Prairie-Chickens  

Science Conference Proceedings (OSTI)

Executive Summary 1. We investigated the impacts of wind power development on the demography, movements, and population genetics of Greater Prairie-Chickens (Tympanuchus cupido) at three sites in northcentral and eastern Kansas for a 7-year period. Only 1 of 3 sites was developed for wind power, the 201MW Meridan Way Wind Power Facility at the Smoky Hills site in northcentral Kansas. Our project report is based on population data for prairie chickens collected during a 2-year preconstruction period (2007-2008), a 3-year postconstruction period (2009-2011) and one final year of lek surveys (2012). Where relevant, we present preconstruction data from our field studies at reference sites in the northern Flint Hills (2007-2009) and southern Flint Hills (2006-2008). 2. We addressed seven potential impacts of wind power development on prairie chickens: lek attendance, mating behavior, use of breeding habitat, fecundity rates, natal dispersal, survival rates, and population numbers. Our analyses of pre- and postconstruction impacts are based on an analysis of covariance design where we modeled population performance as a function of treatment period, distance to eventual or actual site of the nearest wind turbine, and the interaction of these factors. Our demographic and movement data from the 6-year study period at the Smoky Hills site included 23 lek sites, 251 radio-marked females monitored for 287 bird-years, and 264 nesting attempts. Our genetic data were based on genotypes of 1,760 females, males and chicks that were screened with a set of 27 microsatellite markers that were optimized in the lab. 3. In our analyses of lek attendance, the annual probability of lek persistence during the preconstruction period was ~0.9. During the postconstruction period, distance to nearest turbine did not have a significant effect on the probability of lek persistence. However, the probability of lek persistence increased from 0.69 at 0 m to 0.89 at 30 km from turbines, and most abandoned lek sites were located 0.9 for leks of 10 or more males. Large leks in grasslands should be a higher priority for conservation. Overall, wind power development had a weak effect on the annual probability of lek persistence. 3. We used molecular methods to investigate the mating behavior of prairie chickens. The prevailing view for lek-mating grouse is that females mate once to fertilize the clutch and that conspecific nest parasitism is rare. We found evidence that females mate multiple times to fertilize the clutch (8-18% of broods, 4-38% of chicks) and will parasitize nests of other females during egg-laying (~17% of nests). Variable rates of parentage were highest in the fragmented landscapes at the Smoky Hills field site, and were lower at the Flint Hills field site. Comparisons of the pre- and postconstruction periods showed that wind energy development did not affect the mating behaviors of prairie chickens. 4. We examined use of breeding habitats by radio-marked females and conducted separate analyses for nest site selection, and movements of females not attending nests or broods. The landscape was a mix of native prairie and agricultural habitats, and nest site selection was not random because females preferred to nest in grasslands. Nests tended to be closer to turbines during the postconstruction period and there was no evidence of behavioral avoidance of turbines by females during nest site selection. Movements of females not attending nests or broods showed that females crossed the site of the wind power development at higher rates during the preconstruction period (20%) than the postconstruction period (11%), and that movements away from turbines were more frequent during the postconstruction period. Thus, wind power development appears to affect movements in breeding habitats but not nest site s

Market definition study of photovoltaic power for remote villages in developing countries  

DOE Green Energy (OSTI)

The objective of this market definition study is to assess the market potential for the use of photovoltaic power systems for remote villages in developing countries. The approach used was to conduct an in-depth literature search followed by in-country surveys of selected developing countries in Africa, the Middle East, Southeast Asia, and Latin America. The purpose of these surveys was to determine the current energy situation in these countries, the level of rural electrification activity, their knowledge and interest in solar and specifically photovoltaics, their financial resource capability, and the probability of development of a market for photovoltaics based on these and other factors. Findings are presented. The conclusion reached by the survey is that there is a significant market potential for photovoltaics in village power applications in developing countries. Extrapolation of the number of unelectrified villages results in an estimated potential of as much as 20,000 MWp, a potential similar in magnitude to previous UN and World Bank estimates. Recommendations for market stimulation are presented. (WHK)

Oak Ridge National Laboratory Wireless Power Transfer Development for Sustainable Campus Initiative  

SciTech Connect

Wireless power transfer (WPT) is a convenient, safe, and autonomous means for electric and plug-in hybrid electric vehicle charging that has seen rapid growth in recent years for stationary applications. WPT does not require bulky contacts, plugs, and wires, is not affected by dirt or weather conditions, and is as efficient as conventional charging systems. This study summarizes some of the recent Sustainable Campus Initiative activities of Oak Ridge National Laboratory (ORNL) in WPT charging of an on-campus vehicle (a Toyota Prius plug-in hybrid electric vehicle). Laboratory development of the WPT coils, high-frequency power inverter, and overall systems integration are discussed. Results cover the coil performance testing at different operating frequencies, airgaps, and misalignments. Some of the experimental results of insertion loss due to roadway surfacing materials in the air-gap are presented. Experimental lessons learned are also covered in this study.

Research and development of the Osmo-Hydro Power heat engine. Final report  

SciTech Connect

The Osmo-Hydro Power (OHP) or Pressure-Retarded Osmosis (PRO) heat engine is a possible means for producing economical electric power from low-temperature heat sources. The engine utilizes semipermeable membranes to cause the permeation of a solvent from a dilute low-pressure solution to a concentrated high-pressure solution. The potential energy thus acquired is converted to useful energy by means of a turbogenerator. The process can be considered as one in which the free energy of mixing is converted to useful power. By appropriate application of a heat source and a heat sink, the original dilute and concentrated solutions are recovered, thus completing the heat engine cycle. The results of this initial project to study osmotic power generation from waste heat indicate what research paths must be followed to continue the development of distillation and conjugation as unmixing methods. In addition, precipitation and stratification have been shown to be desirable because of the possibility of readily matching a binary system with either a membrane presently available or one readily modified from an existing membrane. The OHP heat engine in its ultimate development would have the following general characteristics: it would be able to utilize low-grade heat sources, such as unconcentrated solar energy or waste heat below 100/sup 0/C., heat sources as low as 50/sup 0/C can be used; the engine should be able to produce electricity for 0.12 $/kWh, or less, but the thermal efficiency will be less than 25% of Carnot efficiency at the same temperature limits; and the engine would be modular; i.e., it could be scaled up or down largely by adding or subtracting discrete permeator and heat exchanger units.

Concentrating Solar Power - Molten Salt Pump Development, Final Technical Report (Phase 1)  

DOE Green Energy (OSTI)

The purpose of this project is to develop a long shafted pump to operate at high temperatures for the purpose of producing energy with renewable resources. In Phase I of this three phase project we developed molten salt pump requirements, evaluated existing hardware designs for necessary modifications, developed a preliminary design of the pump concept, and developed refined cost estimates for Phase II and Phase III of the project. The decision has been made not to continue the project into Phases II and III. There is an ever increasing world-wide demand for sources of energy. With only a limited supply of fossil fuels, and with the costs to obtain and produce those fuels increasing, sources of renewable energy must be found. Currently, capturing the sun's energy is expensive compared to heritage fossil fuel energy production. However, there are government requirements on Industry to increase the amount of energy generated from renewable resources. The objective of this project is to design, build and test a long-shafted, molten salt pump. This is the type of pump necessary for a molten salt thermal storage system in a commercial-scale solar trough plant. This project is under the Department of Energy (DOE) Solar Energy Technologies Program, managed by the Office of Energy Efficiency and Renewable Energy. To reduce the levelized cost of energy (LCOE), and to meet the requirements of 'tomorrows' demand, technical innovations are needed. The DOE is committed to reducing the LCOE to 7-10 cents/kWh by 2015, and to 5-7 cents/kWh by 2020. To accomplish these goals, the performance envelope for commercial use of long-shafted molten salt pumps must be expanded. The intent of this project is to verify acceptable operation of pump components in the type of molten salt (thermal storage medium) used in commercial power plants today. Field testing will be necessary to verify the integrity of the pump design, and thus reduce the risk to industry. While the primary goal is to design a pump for a trough solar power plant system, the intent is for the design to be extensible to a solar power tower application. This can be accomplished by adding pumping stages to increase the discharge pressure to the levels necessary for a solar power tower application. This report incorporates all available conceptual design information completed for this project in Phase I.

Development of fundamental power coupler for high-current superconducting RF cavity  

SciTech Connect

Brookhaven National Laboratory took a project of developing a 704 MHz five-cell superconducting RF cavity for high-current linacs, including Energy Recovery Linac (ERL) for planned electron-hadron collider eRHIC. The cavity will be fed by a high-power RF amplifier using a coaxial Fundamental Power Coupler (FPC), which delivers 20 kW of CW RF power to the cavity. The design of FPC is one of the important aspects as one has to take into account the heat losses dissipated on the surface of the conductor by RF fields along with that of the static heat load. Using a simple simulation model we show the temperature profile and the heat load dissipated along the coupler length. To minimize the heat load on FPC near the cavity end, a thermal intercept is required at an appropriate location on FPC. A 10 K intercept was chosen and its location optimized with our simulation code. The requirement on the helium gas flow rate for the effective heat removal from the thermal intercept is also discussed.

Direct methanol fuel cells: Developments for portable power and for potential transportation applications  

DOE Green Energy (OSTI)

The authors describe here results of recent efforts at Los Alamos National Laboratory (LANL), devoted to potential application of Direct Methanol Fuel Cells (DMFCs) as (1) portable power sources at the 50 W level, and (2) primary power sources for electric vehicles. In general, DMFC R and D efforts focus on further improvements in anode catalytic activity, fuel utilization (as related to methanol crossover) and air cathode performance in the presence of the presence of the significant flux of aqueous methanol from anode to cathode. There are significant differences between technical parameters and targets for the two different DMFC applications, which the authors have addressed. They include the lower cell temperature (about 60 C) preferred in portable power vs. operation around 100 C as target temperature for transportation applications, and the much stronger concern for cost of catalyst and any other stack materials in DMFCs developed for potential transportation applications. Most, if not all, recent DMFC work for either portable power or potential transportation applications has strongly focused on cells with polymeric (primarily PFSA) membrane electrolytes. In work at LANL, thin film catalysts bonded to the membrane, e.g., by the decal method, provided best results in terms of catalyst utilization and overall cell performance. In most tests, the single DMFC hardware consisted of uncatalyzed carbon-cloth gas-diffusion backings and graphite blocks with machined serpentine flow channels--quite similar to hardware employed in work with hydrogen/air PEFCs. However, the machined graphite hardware has recently been replaced by alternative, non-machined flow-field/bipolar plates, which enables effective air and aqueous methanol solution distribution along an active area of 50 cm{sup 2}, at a pitch per cell of 2 mm.

Materials physics and device development for improved efficiency of GaN HEMT high power amplifiers.  

SciTech Connect

GaN-based microwave power amplifiers have been identified as critical components in Sandia's next generation micro-Synthetic-Aperture-Radar (SAR) operating at X-band and Ku-band (10-18 GHz). To miniaturize SAR, GaN-based amplifiers are necessary to replace bulky traveling wave tubes. Specifically, for micro-SAR development, highly reliable GaN high electron mobility transistors (HEMTs), which have delivered a factor of 10 times improvement in power performance compared to GaAs, need to be developed. Despite the great promise of GaN HEMTs, problems associated with nitride materials growth currently limit gain, linearity, power-added-efficiency, reproducibility, and reliability. These material quality issues are primarily due to heteroepitaxial growth of GaN on lattice mismatched substrates. Because SiC provides the best lattice match and thermal conductivity, SiC is currently the substrate of choice for GaN-based microwave amplifiers. Obviously for GaN-based HEMTs to fully realize their tremendous promise, several challenges related to GaN heteroepitaxy on SiC must be solved. For this LDRD, we conducted a concerted effort to resolve materials issues through in-depth research on GaN/AlGaN growth on SiC. Repeatable growth processes were developed which enabled basic studies of these device layers as well as full fabrication of microwave amplifiers. Detailed studies of the GaN and AlGaN growth of SiC were conducted and techniques to measure the structural and electrical properties of the layers were developed. Problems that limit device performance were investigated, including electron traps, dislocations, the quality of semi-insulating GaN, the GaN/AlGaN interface roughness, and surface pinning of the AlGaN gate. Surface charge was reduced by developing silicon nitride passivation. Constant feedback between material properties, physical understanding, and device performance enabled rapid progress which eventually led to the successful fabrication of state of the art HEMT transistors and amplifiers.

Engineering Development of Coal-Fired High-Performance Power Systems  

SciTech Connect

A High Performance Power System (HIPPS) is being developed. This system is a coal-fired, combined cycle plant with indirect heating of gas turbine air. Foster Wheeler Development Corporation and a team consisting of Foster Wheeler Energy Corporation, Bechtel Corporation, University of Tennessee Space Institute and Westinghouse Electric Corporation are developing this system. In Phase 1 of the project, a conceptual design of a commercial plant was developed. Technical and economic analyses indicated that the plant would meet the goals of the project which include a 47 percent efficiency (HHV) and a 10 percent lower cost of electricity than an equivalent size PC plant. The concept uses a pyrolysis process to convert coal into fuel gas and char. The char is fired in a High Temperature Advanced Furnace (HITAF). The HITAF is a pulverized fuel-fired boiler/air heater where steam is generated and gas turbine air is indirectly heated. The fuel gas generated in the pyrolyzer is then used to heat the gas turbine air further before it enters the gas turbine. The project is currently in Phase 2 which includes engineering analysis, laboratory testing and pilot plant testing. Research and development is being done on the HIPPS systems that are not commercial or being developed on other projects. Pilot plant testing of the pyrolyzer subsystem and the char combustion subsystem are being done separately, and after each experimental program has been completed, a larger scale pyrolyzer will be tested at the Power Systems Development Facility (PSDF) in Wilsonville, AL. The facility is equipped with a gas turbine and a topping combustor, and as such, will provide an opportunity to evaluate integrated pyrolyzer and turbine operation. This report addresses the areas of technical progress for this quarter. Detailed design of the components to be used to for the circulating bed gasification tests is underway. The circulating fluidized bed will allow for easy scale-up to larger size plants. The existing pyrolyzer will be outfitted with a cyclone and a j-valve to capture and reinject char into the lower combustion zone. Additional development work has been performed to evaluate advanced cycles utilizing the HIPPS system concept.
