Temperature Utilization of Geothermal Resources Geothermal Temperature Utilization of Geothermal Resources Geothermal Project Jump to: navigation, search Last modified on July 22, 2011. Project Title Analysis of Low-Temperature Utilization of Geothermal Resources Project Type / Topic 1 Recovery Act: Enhanced Geothermal Systems Component Research and Development/Analysis Project Type / Topic 2 Geothermal Analysis Project Description In this proposal West Virginia University (WVU) outline a project which will perform an in-depth analysis of the low-temperature geothermal resources that dominate the eastern half of the United States. Full realization of the potential of what might be considered "low-grade" geothermal resources will require the examination many more uses for the heat than traditional electricity generation. To demonstrate that geothermal energy truly has the potential to be a national energy source the project will be designing, assessing, and evaluating innovative uses for geothermal-produced water such as hybrid biomass-geothermal cogeneration of electricity and district heating and efficiency improvements to the use of cellulosic biomass in addition to utilization of geothermal in district heating for community redevelopment projects.

Southern New Mexico low temperature geothermal resource economic analysis  

DOE Green Energy (OSTI)

This report presents an overview of geothermal resource development for three-low temperature (i.e, <200{degree}F) sites in southern New Mexico: the Lower Animas Valley, the Las Cruces East Mesa, and Truth or Consequences. This report is intended to provide potential geothermal developers with detailed information on each site for planning and decision making purposes. Included in the overview for each site is both a full site characterization and an economic analysis of development costs associated with the construction and operation of both geothermal and fresh water systems at each of the three locations. The economic analysis focuses on providing utility services to a commercial greenhouse because greenhouse operations are among the most likely candidates for use of the resource base. 9 tabs., 8 figs.

Mountain home known geothermal resource area: an environmental analysis  

DOE Green Energy (OSTI)

The Mountain Home KGRA encompasses an area of 3853 hectares (ha) at the foot of the Mount Bennett Hills in Elmore County, Idaho. The site is associated with an arid climate and high winds that generate an acute dust problem. The KGRA lies adjacent to the northwest-southeast trending fault zone that reflects the northern boundary of the western Snake River Plain graben. Data indicate that a careful analysis of the subsidence potential is needed prior to extensive geothermal development. Surface water resources are confined to several small creeks. Lands are utilized for irrigated farmlands and rangeland for livestock. There are no apparent soil limitations to geothermal development. Sage grouse and mule deer are the major species of concern. The potential of locating significant heritage resources other than the Oregon Trail or the bathhouse debris appears to be relatively slight.

Vulcan Hot Springs known geothermal resource area: an environmental analysis  

DOE Green Energy (OSTI)

The Vulcan Hot Springs known geothermal resource area (KGRA) is one of the more remote KGRAs in Idaho. The chemistry of Vulcan Hot Springs indicates a subsurface resource temperature of 147/sup 0/C, which may be high enough for power generation. An analysis of the limited data available on climate, meteorology, and air quality indicates few geothermal development concerns in these areas. The KGRA is located on the edge of the Idaho Batholith on a north-trending lineament which may be a factor in the presence of the hot springs. An occasional earthquake of magnitude 7 or greater may be expected in the region. Subsidence or elevation as a result of geothermal development in the KGRA do not appear to be of concern. Fragile granitic soils on steep slopes in the KGRA are unstable and may restrict development. The South fork of the Salmon River, the primary stream in the region, is an important salmon spawning grounds. Stolle Meadows, on the edge of the KGRA, is used as a wintering and calving area for elk, and access to the area is limited during this period. Socioeconomic and demographic surveys indicate that facilities and services will probably not be significantly impacted by development. Known heritage resources in the KGRA include two sites and the potential for additional cultural sites is significant.

Crane Creek known geothermal resource area: an environmental analysis  

DOE Green Energy (OSTI)

The Crane Creek known geothermal resource area (KGRA) is located in Washington County, in southwestern Idaho. Estimated hydrothermal resource temperatures for the region are 166/sup 0/C (Na-K-Ca) and 176/sup 0/C (quartz). The KGRA is situated along the west side of the north-south trending western Idaho Fault Zone. Historic seismicity data for the region identify earthquake activity within 50 km. The hot springs surface along the margin of a siliceous sinter terrace or in adjacent sediments. Approximately 75% of the KGRA is underlain by shallow, stony soils on steep slopes indicating topographic and drainage limitations to geothermal development. Species of concern include sage grouse, antelope, and mule deer. There is a high probability of finding significant prehistoric cultural resources within the proposed area of development.

DOE Green Energy (OSTI)

The Bruneau Known Geothermal Resource Area (KGRA) is part of the Bruneau-Grandview thermal anomaly, the largest geothermal area in the western US. This part of Owyhee County is the driest part of Idaho. The KGRA is associated with the southern boundary fault zone of the Snake River Plain. Thermal water, produced from numerous artesian wells in the region, is supplied from two major aquifers. Ecological concerns include the threatened Astragalus mulfordiae and the numerous birds of prey nesting in the Snake River canyon northwest of the KGRA. Extensive geothermal development may strain the limited health care facilities in the county. Ethnographic information suggests that there is a high probability of prehistoric cultural materials being remnant in the Hot Spring locality.

The KGRA is located in the driest area of Idaho and annual precipitation averages 230 mm. The potential of subsidence and slope failure is high in sediments of the Glenns Ferry Formation and Idaho Group found in the KGRA. A major concern is the potential impact of geothermal development on the Snake River Birds of Prey Natural Area which overlaps the KGRA. Any significant economic growth in Owyhee County may strain the ability of the limited health facilities in the county. The Idaho Archaeological survey has located 46 archaeological sites within the KGRA.

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.

National forecast for geothermal resource exploration and development with techniques for policy analysis and resource assessment  

DOE Green Energy (OSTI)

The backgrund, structure and use of modern forecasting methods for estimating the future development of geothermal energy in the United States are documented. The forecasting instrument may be divided into two sequential submodels. The first predicts the timing and quality of future geothermal resource discoveries from an underlying resource base. This resource base represents an expansion of the widely-publicized USGS Circular 790. The second submodel forecasts the rate and extent of utilization of geothermal resource discoveries. It is based on the joint investment behavior of resource developers and potential users as statistically determined from extensive industry interviews. It is concluded that geothermal resource development, especially for electric power development, will play an increasingly significant role in meeting US energy demands over the next 2 decades. Depending on the extent of R and D achievements in related areas of geosciences and technology, expected geothermal power development will reach between 7700 and 17300 Mwe by the year 2000. This represents between 8 and 18% of the expected electric energy demand (GWh) in western and northwestern states.

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.

Geothermal investment and policy analysis with evaluation of California and Utah resource areas  

DOE Green Energy (OSTI)

A geothermal investment decision model was developed which, when coupled to a site-specific stochastic cash flow model, estimates the conditional probability of a positive decision to invest in the development of geothermal resource areas. The geothermal cash flow model, the investment decision model and their applications for assessing the likely development potential of nine geothermal resource areas in California and Utah are described. The sensitivity of this investment behavior to several policy incentives is also analyzed and discussed.

Geothermal investigations in Idaho: Geothermal resource analysis in Twin Falls County, Idaho:  

DOE Green Energy (OSTI)

Increased utilization of the geothermal resource in the Twin Falls - Banbury area of southern Idaho has resulted in noticeable declines in the artesian head of the system. In order to determine the nature of the declines, a network of wells was identified for monitoring shut-in pressures and temperatures. In addition, a compilation of data and reconnaissance of the areal geology was undertaken in order to better understand the geologic framework and its relationship to the occurrence of the thermal waters in the system. The results of the monitoring indicate that while water temperatures have remained constant, the system shows a gradual overall decline in artesian pressure superimposed on fluctuations caused by seasonal use of the system. Well testing and the similarity of hydrographs resulting from well monitoring throughout the area suggest that there are no major hydrologic barriers to thermal water movement in the system and that wells are affected by increases and decreases in utilization of nearby wells. 46 refs., 13 figs., 1 tab.

Geothermal resources of Montana  

DOE Green Energy (OSTI)

The Montana Bureau of Mines and Geology has updated its inventory of low and moderate temperature resources for the state and has assisted the Oregon Institute of Technology - GeoHeat Center and the University of Utah Research Institute in prioritizing and collocating important geothermal resource areas. The database compiled for this assessment contains information on location, flow, water chemistry, and estimated reservoir temperatures for 267 geothermal well and springs in Montana. For this assessment, the minimum temperature for low-temperature resource is defined as 10{degree} C above the mean annual air temperature at the surface. The maximum temperature for a moderate-temperature resource is defined as greater than 50{degree} C. Approximately 12% of the wells and springs in the database have temperatures above 50{degree} C, 17% are between 30{degree} and 50{degree} C, 29% are between 20{degree} and 30{degree}C, and 42% are between 10{degree} and 20{degree} C. Low and moderate temperature wells and springs can be found in nearly all areas of Montana, but most are in the western third of the state. Information sources for the current database include the MBMG Ground Water Information Center, the USGS statewide database, the USGS GEOTHERM database, and new information collected as part of this program. Five areas of Montana were identified for consideration in future investigations of geothermal development. The areas identified are those near Bozeman, Ennis, Butte, Boulder, and Camas Prairie. These areas were chosen based on the potential of the resource and its proximity to population centers.

Geothermal resource analysis in Twin Falls County, Idaho  

DOE Green Energy (OSTI)

Thermal water is prevalent throughout central Twin Falls County. Most wells and springs that occur in the area produce thermal water from fractures in the Idavada Volcanics. However, in an area east of Hollister, thermal water issues from fractures in the Paleozoic rocks. In an attempt to explain the hydrothermal relationship between these two reservoir rocks, one composite model for the entire geothermal system in the area is proposed. As with other conceptual models of the system, available geologic, hydrologic, and geochemical data were used to develop the model. The chemistry of the thermal water appears to be strongly governed by the chemical composition of the rocks that it comes in contact with and the length of time that it is exposed to them. The shorter flow paths to the south appear to occur entirely within the Paleozoic rocks, according to the calcium bicarbonate chemistry of the thermal water. As the flow paths become progressively longer toward the north, the thermal waters apparently encounter the silicic volcanics during their ascent. The chemistries of the thermal waters gradually equilibrate to the new host rock conditions and lose their Paleozoic signatures as exposure time increases. Ultimately, the chemistry of the thermal water changes to a sodium bicarbonate type.

Geothermal exploration and resource assessment: R and D program benefit/cost analysis  

DOE Green Energy (OSTI)

The Geothermal Exploration and Resource and Reservoir Assessment (GERRA) Research and Development (R and D) Program of the Department of Energy was analyzed to evaluate its cost effectiveness and relevance to the needs of the geothermal exploration industry. This analysis was conducted in three phases. The first phase involved a review of the state-of-the-art and an identification of major R and D needs, followed by a quantitative assessment of the benefits expected from the achievement of some realistic targets for reducing the proportion of unsuccessful (non-productive) wells drilled in the course of exploration for a reservoir. In the second phase, questionnaires concerning the utility, effectiveness and need for improvement of certain commonly used exploration techniques were mailed to a set of 72 individuals active in geothermal exploration. The third phase consisted of in-person interviews with well recognized experts in geothermal exploration. The results of the quantitative analysis suggest that a benefit/cost ratio exceeding ten can be realized for the R and D expenditure by achieving a relatively modest target of improving the current weighted average exploratory drilling success ratio by 3 percentage points (i.e., from 0.24 to 0.27). The responses to the mailed questionnaires indicated that the emphasis of R and D should be on improving the data interpretation capability rather than the data collection (measurement) capability.Liquid geochemistry, seismic methods and thermal methods were identified as the techniques deserving most attention. The in-person interviews revealed that the industry is more concerned about finding buyers (utilities) for the discovered resources than about finding new resources in the near term.

UWC geothermal resource exploration  

DOE Green Energy (OSTI)

A program was developed to explore the strength of the geothermal and hot dry rock (HDR) resource at the Montezuma Hot Springs at the United World College (UWC). The purpose of the UWC {number_sign}1 well is to obtain hydrologic, geologic, and temperature information for ongoing geothermal evaluation of the Montezuma Hot Springs area. If sufficient fluids are encountered, the hole will be cased with a 4 1/2 inch production casing and re-permitted as a geothermal low-temperature well. If no fluid is encountered, the well will be abandoned per Oil Conservation Division regulation. The objectives of the exploration are to evaluate the resource potential to provide space heating for the entire campus of the United World College, determine the effect of a well on the Hot Springs outflow, accurately measure the UWC heating loads versus time, evaluate the potential to support local thermal industry development, assess the feasibility of HDR development, and create an educational program from the collection of data derived from the research effort.

Geothermal Energy Resource Assessment  

DOE Green Energy (OSTI)

This report covers the objectives and the status of a long-range program to develop techniques for assessing the resource potential of liquid-dominated geothermal systems. Field studies underway in northern Nevada comprise a systematic integrated program of geologic, geophysical, and geochemical measurements, necessary to specify a drilling program encompassing heat flow holes, deep calibration holes, and ultimately, deep test wells. The status of Nevada field activities is described. The areas under study are in a region characterized by high heat flow where temperatures at depth in some geothermal systems exceed 180 C. Areas presently being examined include Beowawe Hot Springs in Whirlwind Valley. Buffalo Valley Hot Springs, Leach Hot Springs in Grass Valley, and Kyle Hot Springs in Buena Vista Valley. Geologic studies encompass detailed examinations of structure and lithology to establish the geologic framework of the areas. The geothermal occurrences are characterized by zones of intense fault intersection, which furnish permeable channelways for the introduction of meteoric water into regions of high temperature at depth.

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.

Geothermal resource data base: Arizona  

DOE Green Energy (OSTI)

This report provides a compilation of geothermal well and spring information in Arizona up to 1993. This report and data base are a part of a larger congressionally-funded national effort to encourage and assist geothermal direct-use. In 1991, the US Department of Energy, Geothermal Division (DOE/GD) began a Low-Temperature Geothermal Resources and Technology Transfer Program. Phase 1 of this program includes updating the inventory of wells and springs of ten western states and placing these data into a digital format that is universally accessible to the PC. The Oregon Institute of Technology GeoHeat Center (OIT) administers the program and the University of Utah Earth Sciences and Resources Institute (ESRI) provides technical direction. In recent years, the primary growth in geothermal use in Arizona has occurred in aquaculture. Other uses include minor space heating and supply of warm mineral waters for health spas.

Analysis of binary thermodynamic cycles for a moderately low-temperature geothermal resource  

DOE Green Energy (OSTI)

Analyses of a number of geothermal binary-cycles were made with the objective of finding a cycle which can produce low-cost electrical energy from a moderately low-temperature geothermal resource. Cycles were screened which included isobutane, pentane, cis-2-butene, and several mixed-hydrocarbon working fluids. Dual- and triple-boiling cycles were analyzed. Both shell-and-tube and direct-contact boilers, heaters, and condensers were assessed. A geothermal fluid (geo-fluid), typical of Raft River resource conditions was assumed, which has a temperature of 290/sup 0/F and 52 parts per million dissolved nitrogen. Special emphasis in the analyses was directed toward investigation of several methods for keeping the loss of working fluid for the cycle at an acceptable level. It was concluded that for the Raft River geo-fluid, the direct-contact cycle has a potential for net geofluid utilization effectiveness values, (watt-hr/lbm geo-fluid) equivalent to those of the shell-and-tube cycle. Therefore, because of the lower cost of direct-contact components, a potential exists for the direct-contact plant to produce lower cost electrical energy than a comparable shell-and-tube plant. Advanced cycles were assessed which showed improvements in net geo-fluid utilization effectivness, relative to the first Raft River 5-MW Pilot Plant (dual-boiling, shell-and-tube isobutane cycle), of up to 19%.

Tracer test analysis of the Klamath Falls geothermal resource: a comparison of models  

DOE Green Energy (OSTI)

Two tracer tests on doublet systems in a fractured geothermal system were carried out in Klamath Falls, Oregon. The purpose of the tests were to obtain data which would lead to information about the reservoir and to test the applicability of current tracer flow models. The results show rapid breakthrough times and indicate fracture flow with vigorous mixing of injector fluid before production of same. This leads to the idea that thermal breakthrough is not directly related to tracer breakthrough in the Klamath Union doublet system. There has been no long-term enthalpy loss from exploiting the resource for 40 years. In order to reduce the data, models were developed to analyze the results. Along with a porous media flow model two mathematical models developed to analyze fractured geothermal systems are used to help decipher the various tracer return curves. The flow of tracers in doublet systems was investigated. A mathematical description is used for tracer flow through fractures as a function of time and various nonlinear parameters which can be found using a curve fitting technique. This allows the reservoir to be qualitatively defined. These models fit the data well, but point to the fact that future improvement needs to be considered for a clearer and more quantitative understanding of fractured geothermal systems. 22 refs., 32 figs., 11 tabs.

Geothermal resource development: laws and regulations  

DOE Green Energy (OSTI)

The development of geothermal resources in California is becoming of increasing interest because of the large amounts of these resources in the state. In response to this interest in development, the legislature and regulatory bodies have taken actions to increase geothermal power production. The important federal and California laws on the subject are presented and discussed. Pertinent federal and state provisions are compared, and inconsistencies are discussed. An important concept that needs clarification is the manner of designating an area as a ''known geothermal resource area.'' The question of designating geothermal resource as a mineral is not completely resolved, although there is authority tending toward the finding that it is a mineral.

Geothermal resources of southern Idaho  

DOE Green Energy (OSTI)

The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150 C. Water from many of these systems is valuable for direct heat applications. A majority of the known and inferred geothermal resources of southern Idaho underlie the Snake River Plain. However, major uncertainties exist concerning the geology and temperatures beneath the plain. The largest hydrothermal system in Idaho is in the Bruneau-Grang View area of the western Snake River Plain with a calculated reservoir temperature of 107 C and an energy of 4.5 x 10 to the 20th power joules. No evidence of higher temperature water associated with this system was found. Although the geology of the eastern Snake River Plain suggests that a large thermal anomaly may underlie this area of the plain, direct evidence of high temperatures was not found. Large volumes of water at temperatures between 90 and 150 C probably exist along the margins of the Snake River Plain and in local areas north and south of the plain.

DOE Green Energy (OSTI)

Some 80 countries are potentially interested in geothermal energy development, and about 50 have quantifiable geothermal utilization at present. Electricity is produced from geothermal in 21 countries (total 38 TWh/a) and direct application is recorded in 35 countries (34 TWh/a). Geothermal electricity production is equally common in industrialized and developing countries, but plays a more important role in the developing countries. Apart from China, direct use is mainly in the industrialized countries and Central and East Europe. There is a surplus of trained geothermal manpower in many industrialized countries. Most of the developing countries as well as Central and East Europe countries still lack trained manpower. The Philippines (PNOC) have demonstrated how a nation can build up a strong geothermal workforce in an exemplary way. Data from Iceland shows how the geothermal manpower needs of a country gradually change from the exploration and field development to monitoring and operations.

Methods for regional assessment of geothermal resources  

DOE Green Energy (OSTI)

The techniques in geothermal resource assessment are summarized, terminology and assumptions are clarified, and a foundation for the development of optimum geothermal resource assessment methodology is provided. A logical, sequential subdivision of the geothermal resource base is proposed, accepting its definition as all the heat in the earth's crust under a given area, measured from mean annual temperature. That part of the resource base which is shallow enough to be tapped by production drilling is termed the accessible resource base, and it in turn is divided into useful and residual components. The useful component (i.e., the heat that could reasonably be extracted at costs competitive with other forms of energy at some specified future time) is termed the geothermal resource. This in turn is divided into economic and subeconomic components, based on conditions existing at the time of assessment. In the format of a McKelvey diagram, this logic defines the vertical axis (degree of economic feasibility). The horizontal axis (degree of geologic assurance) contains identified and undiscovered components. Reserve is then designated as the identified economic resource. All categories should be expressed in units of heat, with resource and reserve figures calculated at wellhead, prior to the inevitable large losses inherent in any practical thermal use or in conversion to electricity. Methods for assessing geothermal resources can be grouped into 4 classes: (a) surface thermal flux, (b) volume, (c) planar fracture, and (d) magmatic heat budget. The volume method appears to be most useful.

Geothermal Energy - An Emerging Resource  

SciTech Connect

Address on the Department of Energy's overall energy policy, the role of alternative energy sources within the policy framework, and expectations for geothermal energy. Commendation of the industry's decision to pursue the longer-term field effort while demand for geothermal energy is low, and thus prepare for a substantial geothermal contribution to the nation's energy security.

National Geothermal Information Resource annual report, 1977  

DOE Green Energy (OSTI)

The National Geothermal Information Resource (GRID) of the Lawrence Berkeley Laboratory is chartered by the U.S. Department of Energy (DOE) to provide critically evaluated data and other information for the development and utilization of geothermal energy. Included are both site dependent and site independent information related to resource evaluation, electrical and direct utilization, environmental aspects, and the basic properties of aqueous electrolytes. The GRID project is involved in cooperative agreements for the interchange of information and data with other organizations. There are currently three U.S. data centers working to implement the collection and exchange of information on geothermal energy research and production: the DOE Technical Information Center (TIC), Oak Ridge, the GEOTHERM database of the U.S. Geological Survey in Menlo Park, and the GRID project. The data systems of TIC, GEOTHERM and GRID are coordinated for data collection and dissemination, with GRID serving as a clearinghouse having access to files from all geothermal databases including both numerical and bibliographic data. GRID interfaces with DOE/TIC for bibliographic information and with GEOTHERM for certain site-dependent numerical data. The program is organized into four principal areas: (1) basic geothermal energy data; (2) site-dependent data for both electrical and direct utilization; (3) environmental aspects, and (4) data handling development. The four sections of the report are organized in this way.

Exploration Criteria for Low Permeability Geothermal Resources  

DOE Green Energy (OSTI)

The decision to drill deep holes in a prospective geothermal system implies that geothermal energy resources exist at depth. The drill hole location and budget result from hypothesis regarding the location and depth of the resource within the overall system. Although operational decisions normally dictate the practicality of drilling, the characteristics, we must first understand how unique various surface or shallow subsurface data are in assessing the nature of the resource. The following progress report summarizes the results of numerical simulations of heat and mass transport around igneous plutons and the synthesis of geologic data. To date, the results of the study describe the transient nature of thermal resources and the ambiguities which must be accounted for in using current technology to assess the nation's geothermal resources.

Economic incentive of geothermal resource development for direct applications  

DOE Green Energy (OSTI)

As part of a mission-oriented program for accelerating the commercialization of geothermal energy, research is sponsored which concerns the quantitative analysis of investment decisions by industries involved in the development of geothermal resources. The results of a quick-response study conducted during the course of this research are discussed. The report specifically compares the relative investment incentive offered by two categories of geothermal ventures: (a) geothermal electric power projects; and (b) geothermal direct application projects. The attributes of discounted cash flows for several typical projects within each of the two categories are compared and, by using statistically-strong industry decision models previously developed, the likelihood of a favorable investment decision is estimated for each project.

Stratabound geothermal resources in North Dakota and South Dakota  

SciTech Connect

Analysis of all geothermal aquifers in North Dakota and South Dakota indicates an accessible resource base of approximately 21.25 exajoules (10{sup 18} J = 1 exajoule, 10{sup 18} J{approximately}10{sup 15} Btu=1 quad) in North Dakota and approximately 12.25 exajoules in South Dakota. Resource temperatures range from 40{degree}C at depths of about 700 m to 150{degree}C at 4500 m. This resource assessment increases the identified accessible resource base by 31% over the previous assessments. These results imply that the total stratabound geothermal resource in conduction-dominated systems in the United States is two-to-three times greater than some current estimates. The large increase in the identified accessible resource base is primarily due to inclusion of all potential geothermal aquifers in the resource assessment and secondarily due to the expanded data base compiled in this study. These factors were interdependent in that the extensive data base provided the means for inclusion of all potential geothermal aquifers in the analysis. Previous assessments included only well-known aquifer systems and were limited by the amount of available data. 40 refs., 16 figs., 8 tabs.

Geothermal resources of the eastern United States  

DOE Green Energy (OSTI)

The resouces considered are exclusively hydrothermal, and the study was confined to the 35 states east of the Rocky Mountains, excluding the Dakotas. Resource definition in these areas is based entirely on data found in the literature and in the files of a number of state geological offices. The general geology of the eastern United States is outlined. Since the presence of geothermal resources in an area is governed by the area's geology, an attempt to define useful geothermal resources is facilitated by an understanding of the geology of the area being studied. Six relatively homogeneous eastern geologic regions are discussed. The known occurrences of geothermal energy in the eastern United States fall into four categories: warm spring systems, radioactive granite plutons beneath thick sediment covers, abnormally warm aquifers, and deep sedimentary basins with normal temperature gradients.

Geothermal resources of the Alberta Plains  

Science Conference Proceedings (OSTI)

Formation waters of the Alberta Plains are inventoried in a new report prepared for the Renewable Energy Branch, Energy, Mines, and Resources, Canada. Water temperatures, salinities, depths, and the reservoir capacities of the enclosing rocks are included. From geological information and preexisting temperature and gradient data, 21 maps were drawn often rock units and the enclosed fluids. Although some previous site-specific inventories of the geothermal resources of the Alberta Plains have been made, the study is the first comprehensive survey. Capital costs to install geothermal energy recovery operations from scratch are prohibitively high on Canada's Alberta Plains. The geothermal resources there are about 1.5 kilometers deep, and drilling wells to reach them is expensive. For a geothermal recovery operation to be economically feasible, drilling cots must be avoided. One way is through a joint-venture operation with the petroleum industry. A joint venture may be possible because oil extraction often involves the production of large volumes of hot water, a geothermal resource. Typically, after the hot water is brought to the surface with oil, it is injected underground and the heat is never used. Ways to obtain and use this heat follow.

A geothermal resource data base: New Mexico  

DOE Green Energy (OSTI)

This report provides a compilation of geothermal well and spring information in New Mexico up to 1993. Economically important geothermal direct-use development in New Mexico and the widespread use of personal computers (PC) in recent years attest to the need for an easily used and accessible data base of geothermal data in a digital format suitable for the PC. This report and data base are a part of a larger congressionally-funded national effort to encourage and assist geothermal direct-use. In 1991, the US Department of Energy, Geothermal Division (DOE/GD) began a Low Temperature Geothermal Resources and Technology Transfer Program. Phase 1 of this program includes updating the inventory of wells and springs of ten western states and placing these data into a digital format that is universally accessible to the PC. The Oregon Institute of Technology GeoHeat Center (OIT) administers the program and the University of Utah Earth Sciences and Resources Institute (ESRI) provides technical direction.

Geothermal resource utilization: paper and cane sugar industries. Final report  

DOE Green Energy (OSTI)

This study was made as a specific contribution to an overall report by the United States in the area of industrial utilization of geothermal resources. This is part of an overall study in non-electrical uses of geothermal resources for a sub-committee of the North Atlantic Treaty Organization. This study was restricted to the geopressured zone along the Northern Gulf of Mexico Coast. Also, it was limited to utilizing the thermal energy of this ''geoenergy'' resource for process use in the Pulp and Paper Industry and Cane Sugar Industry. For the selected industries and resource area, this report sets forth energy requirements; identifies specific plant and sites; includes diagrams of main processes used; describes process and equipment modifications required; describes energy recovery systems; sets forth waste disposal schemes and problems; and establishes the economics involved. The scope of work included considerable data collection, analysis and documentation. Detailed technical work was done concerning existing processes and modifications to effectively utilize geothermal energy. A brief survey was made of other industries to determine which of these has a high potential for utilizing geothermal energy.

Geothermal resource assessment, South Dakota: Final report  

SciTech Connect

Seven geothermal aquifers in South Dakota contain an accessible resource base of about 11,207 x 10/sup 18/ J. The potentially productive geothermal aquifers are: Deadwood Formation (Cambrian), Winnipeg Formation + Red River Formation + Englewood Limestone (Ordovician through Devonian), Madison Limestone (Mississippian), Minnelusa Formation (Mississippian-Permian), Inyan Kara Group (Cretaceous), and Newcastle Sandstone (Cretaceous). The resource estimate was obtained by first using heat flow, thermal conductivity, temperature gradient, and stratigraphic data to estimate aquifer temperatures. The heat content of each aquifer was determined from the product of the volumetric heat capacity, aquifer volume, and temperature difference between the aquifer and the mean annual temperature for a 14 x 14 grid of 240 km/sup 2/ cells. Geothermal fluid temperatures range from about 120/sup 0/C in the Deadwood Formation in the Williston Basin to about 30/sup 0/C for the Newcastle Sandstone in south-central South Dakota. The area containing the resource lies largely west of the Missouri River. About 10,000 km/sup 2/ of the resource area is characterized by anomalously high heat flow values greater than 100 mW m/sup -2/.

Geothermal resources in California: potentials and problems  

DOE Green Energy (OSTI)

The technology, cost and potential of geothermal resources in California are examined. The production of power from dry stream fields is expanding in Northern California, at The Geysers, at costs that compare favorably with alternate means of generation. The possibility exists that economic production of power can be started in the Imperial Valley, but numerous issues remain to be resolved; chief among them is the demonstration that commercially valuable aquifers indeed exist. The production of demineralized water from the geothermal fluids of the Imperial Valley depends, among other things, upon the identification of other sources of water for power plant cooling, or for reservoir reinjection, should it be necessary to avoid subsidence. It would appear that water production, without the income-producing capability of associated power generation, is not economically reasonable. The pace of geothermal development at the Geysers could probably be accelerated perhaps offering the opportunity for maintenance of adequate generating reserves should their nuclear construction program be delayed. The unknown factors and risks involved seem to preclude the Imperial Valley resource from being immediately effective in improving the power generation picture in Southern California. However, in the next decade, geothermal power could provide a useful energy increment, perhaps 10 percent of peak load. Associated water production could offer relief for the Imperial Valley in its predicted water quality problem. The pace of public and private development in the Imperial Valley seems incommensurately slow in relation to the potential of the resource. Geothermal power and water production is not intrinsically pollution-free, but appropriate environmental protection is possible.

Analysis of potential geothermal resources and their use: Lebanon Springs area, New York  

DOE Green Energy (OSTI)

The feasibility of using thermal waters at Lebanon Springs or elsewhere in the Capital District of New York as an energy source was studied. To evaluate the area, geologic mapping of the Lebanon Springs, New York, to Williamstown, Massachusetts, area was conducted, and efforts made to locate additional thermal waters besides those already known. In addition to mapping, thermal gradients where measured in twenty-five abandoned water wells, and the silica contents and water temperatures of seventy-eight active domestic water wells were determined. Based on the results of that work, Lebanon Springs appears to be the first choice for a demonstration project, but further exploration may confirm that other areas with good potential exist. A preliminary economic analysis of possible uses in the Town of Lebanon Springs was made, and it was determined that a system combining groundwater heat pumps and a microhydroelectric plant could be applied to heating the town hall, town garage, and high school with significant savings.

Low-temperature geothermal resources of Washington  

DOE Green Energy (OSTI)

This report presents information on the location, physical characteristics, and water chemistry of low-temperature geothermal resources in Washington. The database includes 941 thermal (>20C or 68F) wells, 34 thermal springs, lakes, and fumaroles, and 238 chemical analyses. Most thermal springs occur in the Cascade Range, and many are associated with stratovolcanoes. In contrast, 97 percent of thermal wells are located in the Columbia Basin of southeastern Washington. Some 83.5 percent are located in Adams, Benton, Franklin, Grant, Walla Walla, and Yakima Counties. Yakima County, with 259 thermal wells, has the most. Thermal wells do not seem to owe their origin to local sources of heat, such as cooling magma in the Earth`s upper crust, but to moderate to deep circulation of ground water in extensive aquifers of the Columbia River Basalt Group and interflow sedimentary deposits, under the influence of a moderately elevated (41C/km) average geothermal gradient.

Geothermal resource utilization - Paper and cane sugar indsutries  

SciTech Connect

This paper was prepared from information developed during a study done by DSS Engineers, Inc., under contract from Lawrence Livermore Laboratory. The study was made as a specific contribution to an overall report by the United States in the area of industrial utilization of geothermal resources. This is part of an overall study in nonelectrical uses of geothermal resources for a subcommittee of the North Atlantic Treaty Organization. Due to limited time and funds, it was initially decided to restrict the study to the geopressured zone along the northern Gulf of Mexico Coast. Also, it was to be limited mainly to considering utilizing the thermal energy of this geoenergy resource for process use in the pulp and paper industry and cane sugar industry. For the selected industries and resource area, the final report sets forth energy requirements, identifies specific plant and sites, includes diagrams of main processes used, describes process and equipment modifications required, describes energy-recovery systems, sets forth waste-disposal schemes and problems, and establishes the economics involved. The scope of work included considerable data collection, analysis and documentation. Detailed technical work was done concerning existing processes and modifications to effectively utilize geothermal energy. A brief survey was made of other industries to determine which of these has a high potential for utilizing geothermal energy. Presented in this paper is a summary of the findings of the study, with emphasis on how the thermal energy is extracted and utilized in the processes and on the economics involved.

Environmental research needs for geothermal resources development. Volume I  

DOE Green Energy (OSTI)

A detailed analysis was conducted to determine the adequacy of the total research efforts regarding the potential environmental impacts related to the exploration, drilling, production, and transmission stages of vapor-dominated, liquid-dominated, geopressured, and hot-dry-rock geothermal resources. The following environmental considerations were selected and analyzed in detail: air emissions (hydrogen sulfide, ammonia, mercury, boron, radon, etc.); liquid emissions (brine, and toxic chemicals); land subsidence; seismic activity; and noise. Following the definition of the problem and the assessment of the past and ongoing research efforts, environmental research needs were then recommended based on: (1) the severity of the environmental problems as perceived by literature and contacts with the research community; (2) probability of occurrence; (3) and the research dependency for a solution to that particular problem. The recommended research needs consisted of: (1) an evaluation of the past and ongoing research efforts to ascertain gaps in knowledge for a particular pollutant, process, or control technology; (2) baseline studies of air, soil, water, and ecology around the existing geothermal facilities and in the locations scheduled for future geothermal development; (3) need for the development of appropriate models for predicting concentration and dispersion of pollutants; (4) development of predictive models for potential health and environmental effects associated with geothermal operations; and (5) development of appropriate control technology to destroy, remove or reduce harmful emissions in order to prevent the occurrence of environmental and health hazards and to comply with existing standards and criteria.

Classification of public lands valuable for geothermal steam and associated geothermal resources  

DOE Green Energy (OSTI)

The Organic Act of 1879 (43 USC 31) that established the US Geological Survey provided, among other things, for the classification of the public lands and for the examination of the geological structure, mineral resources, and products of the national domain. In order to provide uniform executive action in classifying public lands, standards for determining which lands are valuable for mineral resources, for example, leasable mineral lands, or for other products are prepared by the US Geological Survey. This report presents the classification standards for determining which Federal lands are classifiable as geothermal steam and associated geothermal resources lands under the Geothermal Steam Act of 1970 (84 Stat. 1566). The concept of a geothermal resouces province is established for classification of lands for the purpose of retention in Federal ownership of rights to geothermal resources upon disposal of Federal lands. A geothermal resources province is defined as an area in which higher than normal temperatures are likely to occur with depth and in which there is a resonable possiblity of finding reservoir rocks that will yield steam or heated fluids to wells. The determination of a known geothermal resources area is made after careful evaluation of the available geologic, geochemical, and geophysical data and any evidence derived from nearby discoveries, competitive interests, and other indicia. The initial classification required by the Geothermal Steam Act of 1970 is presented.

West Texas geothermal resource assessment. Part II. Preliminary utilization assessment of the Trans-Pecos geothermal resource. Final report  

DOE Green Energy (OSTI)

The utilization potential of geothermal resources in Trans-Pecos, Texas was assessed. The potential for both direct use and electric power generation were examined. As with the resource assessment work, the focus was on the Hueco Tanks area in northeastern El Paso County and the Presidio Bolson area in Presidio County. Suitable users of the Hueco Tanks and Presidio Bolson resource areas were identified by matching postulated temperature characteristics of the geothermal resource to the need characteristics of existing users in each resource area. The amount of geothermal energy required and the amount of fossil fuel that geothermal energy would replace were calculated for each of the users identified as suitable. Current data indicate that temperatures in the Hueco Tanks resource area are not high enough for electric power generation, but in at least part of the Presidio Bolson resource area, they may be high enough for electric power generation.

Inventory of geothermal resources in Nebraska. Final report  

DOE Green Energy (OSTI)

The goal of the State Coupled Resource Assessment Program is to identify and evaluate geothermal resources in the state, particularly low-temperature potential. Eight tasks were identified and documented in this report as follows: bottom-hole temperature survey, heat flow and temperature gradient survey, data translation studies, gravity data, substate regions, information dissemination, state geothermal map, and reports. The project had three major products: (1) a map, Geothermal Resources of Nebraska; (2) a significant amount of thermal data collected and documented within the state; and (3) a series of publications, presentations and meetings (documented as an Appendix).

Kamchatka geothermal resources development: Problems and perspectives  

SciTech Connect

There are four long-term exploited geothermal fields in Kamchatka: one steam-water field Pauzhetka (south of Kamchatka peninsula) and three hot water fields: Paratunka (near by town of Petropavlovsk-Kamchatsky) and Esso and Anavgay (center of peninsula). Pauzhetka and Paratunka fields are exploited during almost 28 years. Esso and Anavgay fields are exploited during 25 years. In Pauzhetka 11 MWe geothermal power plant work and on the other fields thermal energy of hot water is directly used. Kamchatka region satisfies energetic demands mainly by organic imported fuels. At the same time electricity produced by geothermal fluids constitutes less than 2 per cent of total region electricity production, and thermal energy produced by geothermal fluids constitutes less than 3 per cent of total region thermal energy production. The main reasons of small geothermal portion in the energy production balance of Kamchatka are briefly discussed. The geothermal development reserves and perspectives of geothermal energy use increase in Kamchatka are outlined.

Geothermal: a review of US geothermal activity and an assessment of the resource availability  

Science Conference Proceedings (OSTI)

This review describes US geothermal activities and assesses resource availability. The future of geothermal activity in the US is uncertain due to slashes in the geothermal program at the US Department of Energy. The question is whether private industry will continue the geothermal exploration and development program. Major cutbacks in the federal budget are in areas designed to accelerate commercial development of hydrothermal energy. Basic research is still funded, at a lower cost level. Areas of research expected to pay off in the near future include drilling technology, well stimulation, energy conversion, and end materials.

Enhanced Geothermal Systems (EGS) R&D Program: US Geothermal Resources Review and Needs Assessment  

DOE Green Energy (OSTI)

The purpose of this report is to lay the groundwork for an emerging process to assess U.S. geothermal resources that might be suitable for development as Enhanced Geothermal Systems (EGS). Interviews of leading geothermists indicate that doing that will be intertwined with updating assessments of U.S. higher-quality hydrothermal resources and reviewing methods for discovering ''hidden'' hydrothermal and EGS resources. The report reviews the history and status of assessment of high-temperature geothermal resources in the United States. Hydrothermal, Enhanced, and Hot Dry Rock resources are addressed. Geopressured geothermal resources are not. There are three main uses of geothermal resource assessments: (1) They inform industry and other interest parties of reasonable estimates of the amounts and likely locations of known and prospective geothermal resources. This provides a basis for private-sector decisions whether or not to enter the geothermal energy business at all, and for where to look for useful resources. (2) They inform government agencies (Federal, State, local) of the same kinds of information. This can inform strategic decisions, such as whether to continue to invest in creating and stimulating a geothermal industry--e.g., through research or financial incentives. And it informs certain agencies, e.g., Department of Interior, about what kinds of tactical operations might be required to support such activities as exploration and leasing. (3) They help the experts who are performing the assessment(s) to clarify their procedures and data, and in turn, provide the other two kinds of users with a more accurate interpretation of what the resulting estimates mean. The process of conducting this assessment brings a spotlight to bear on what has been accomplished in the domain of detecting and understanding reservoirs, in the period since the last major assessment was conducted.

Assessment of geothermal resources of the United States, 1978  

DOE Green Energy (OSTI)

The geothermal resource assessment presented is a refinement and updating of USGS Circular 726. Nonproprietary information available in June 1978 is used to assess geothermal energy in the ground and, when possible, to evaluate the fraction that might be recovered at the surface. Five categories of geothermal energy are discussed: conduction-dominated regimes, igneous-related geothermal systems, high-temperature (> 150/sup 0/C) and intermediate-temperature (90 to 150/sup 0/C) hydrothermal convection systems, low-temperature (< 90/sup 0/C) geothermal waters, and geopressured-geothermal energy (both thermal energy and energy from dissolved methane). Assessment data are presented on three colored maps prepared in cooperation with the National Oceanic and Atmospheric Administration. Separate abstracts were prepared for papers on these five categories.

Geothermal resource area 11, Clark County area development plan  

DOE Green Energy (OSTI)

Geothermal Resource Area 11 includes all of the land in Clark County, Nevada. Within this area are nine geothermal anomalies: Moapa Area, Las Vegas Valley, Black Canyon, Virgin River Narrows, Roger's Springs, Indian Springs, White Rock Springs, Brown's Spring, and Ash Creek Spring. All of the geothermal resources in Clark County have relatively low temperatures. The highest recorded temperature is 145{sup 0}F at Black Canyon. The temperatures of the other resources range from 70 to 90{sup 0}F. Because of the low temperature of the resources and, for the most part, the distance of the resources from any population base, the potential for the development of the resources are considered to be somewhat limited.

Geothermal resource requirements for an energy self-sufficient spaceport  

DOE Green Energy (OSTI)

Geothermal resources in the southwestern United States provide an opportunity for development of isolated spaceports with local energy self-sufficiency. Geothermal resources can provide both thermal energy and electrical energy for the spaceport facility infrastructure and production of hydrogen fuel for the space vehicles. In contrast to hydrothermal resources by which electric power is generated for sale to utilities, hot dry rock (HDR) geothermal resources are more wide-spread and can be more readily developed at desired spaceport locations. This paper reviews a dynamic model used to quantify the HDR resources requirements for a generic spaceport and estimate the necessary reservoir size and heat extraction rate. The paper reviews the distribution of HDR resources in southern California and southern New Mexico, two regions where a first developmental spaceport is likely to be located. Finally, the paper discusses the design of a HDR facility for the generic spaceport and estimates the cost of the locally produced power.

Utilization of U. S. geothermal resources. Final report  

SciTech Connect

This study is concerned with U.S. geothermal resources, their potential for commercial utilization by electric utilities between now and the year 2000, and their impact on the utility industry. USGS estimates of the resources in identified hydrothermal systems were extrapolated to the undiscovered resources marked by hot springs, and further to the blind resources between hot spring areas within the tectonic belts. The resulting estimate of the total hydrothermal resource to a depth of 10,000 ft. is about 100,000 MWe for 30 years with about one-half in undiscovered blind resources, one-fourth in undiscovered hot spring resources, and one-fourth in identified systems. Water rates and direct capital costs for geothermal power plants were evaluated as functions of resource temperature, together with costs and expected flowrates for geothermal wells. Combining these results with the temperature distribution of identified hydrothermal systems, a current supply curve for geothermal energy wa s made. This shows an estimated 20,000 MWe for 30 years potentially producible with current technology from identified resources for direct capital costs of $800/KW or less. The projected supply curve shows an estimated 30,000 to 60,000 MWe for 30 years potentially available at $800/KW or less, in 1976 dollars, taking account of estimated undiscovered resources and probable technical advances.

Geothermal Power Generation as Related to Resource Requirements  

E-Print Network (OSTI)

For the past several years geothermal exploratory work has been conducted in northern Nevada. In conjunction with that effort a proposed 55-MW steam geothermal power plant was considered for initial installation in one of the fields being developed. The characteristics of the geothermal fields under consideration were not firm, with data indicating widely varying downhole temperatures. Thus, neither the resource nor the plant operating conditions could be set. To assist both the ultimate user of the resource, the utility, and the developer of the geothermal field, a series of parametric sensitivity studies were conducted for the initial evaluation of a field vis-a-vis the power plant. Using downhole temperature as the variable, the amount of brine, brine requirements/kWh, and pounds brine/pound of steam to the turbine were ascertained. This was done over a range of downhole temperatures of from 350F to 475F. The studies illustrate the total interdependence of the geothermal resource and its associated power plant. The selection of geothermal steam power plant design conditions must be related to the field in which the plant is located. The results of the work have proven to be valuable in two major respects: (1) to determine the production required of a particular geothermal field to meet electrical generation output and (2) as field characteristics become firm, operating conditions can be defined for the associated power plant.

Potential benefits of geothermal electrical production from hydrothermal resources  

DOE Green Energy (OSTI)

The potential national benefits of geothermal electric energy development from the hydrothermal resources in the West are estimated for several different scenarios. The U.S. electrical economy is simulated by computer using a linear programming optimization technique. Under most of the scenarios, benefits are estimated at $2 to $4 billion over the next 50 years on a discounted present value basis. The electricity production from hydrothermal plants reaches 2 to 4 percent of the national total, which will represent 10 to 20 percent of the installed capacity in the West. Installed geothermal capacity in 1990 is estimated to be 9,000 to 17,000 Mw(e). The geothermal capacity should reach 28,000 to 65,000 Mw(e) by year 2015. The ''most likely'' scenario yields the lower values in the above ranges. Under this scenario geothermal development would save the utility industry $11 billion in capital costs (undiscounted); 32 million separative work units; 64,000 tons of U/sub 3/O/sub 8/; and 700 million barrels of oil. The most favorable scenario for geothermal energy occurs when fossil fuel prices are projected to increase at 5 percent/year. The benefits of geothermal energy then exceed $8 billion on a discounted present value basis. Supply curves were developed for hydrothermal resources based on the recent U.S. Geological Survey (USGS) resource assessment, resource characteristics, and projected power conversion technology and costs. Geothermal plants were selected by the optimizing technique to fill a need for ''light load'' plants. This infers that geothermal plants may be used in the future primarily for load-following purposes.

Geothermal Development and Resource Management in the Yakima Valley : A Guidebook for Local Governments.  

DOE Green Energy (OSTI)

The guidebook defines the barriers to geothermal energy development at all levels of government and proposes ways to overcome these various barriers. In recognition that wholesale development of the region's geothermal resources could create a series of environmental problems and possible conflicts between groundwater users, resource management options are identified as possible ways to ensure the quality and quantity of the resource for future generations. It is important for local governments to get beyond the discussion of the merits of geothermal energy and take positive actions to develop or to encourage the development of the resource. To this end, several sources of technical and financial assistance are described. These sources of assistance can enable local governments and others to take action should they choose to do so. Even though the Yakima Valley is the setting for the analysis of local issues that could hamper geothermal development, this guidebook could be used by any locale with geothermal energy resources. The guidebook is not a scientific manual, but rather a policy document written especially for local government staff and officials who do not have technical backgrounds in geology or hydrology.

Geothermal resource area 9: Nye County. Area development plan  

DOE Green Energy (OSTI)

Geothermal Resource area 9 encompasses all of Nye County, Nevada. Within this area there are many different known geothermal sites ranging in temperature from 70/sup 0/ to over 265/sup 0/ F. Fifteen of the more major sites have been selected for evaluation in this Area Development Plan. Various potential uses of the energy found at each of the resource sites discussed in this Area Development Plan were determined after evaluating the area's physical characteristics, land ownership and land use patterns, existing population and projected growth rates, and transportation facilities, and comparing those with the site specific resource characteristics. The uses considered were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories certain subdivisions were considered separately. The findings about each of the 15 geothermal sites considered in this Area Development Plan are summarized.

Geothermal resource assessment of Ouray, Colorado. Resource series 15  

DOE Green Energy (OSTI)

In 1979, a program was initiated to delineate the geological features controlling the occurrence of geothermal resources in Colorado. In the Ouray area, this effort consisted of geological mapping, soil mercury geochemical surveys and resistivity geophysical surveys. The soil mercury obtained inconclusive results, with the Box Canyon area indicating a few anomalous values, but these values are questionable and probably are due to the hot spring activity and mineralization within the Leadville limestone rock. One isolated locality indicating anomalous values was near the Radium Springs pool and ball park, but this appears to be related to warm waters leaking from a buried pipe or from the Uncompahgre River. The electrical resistivity survey however, indicated several areas of low resistivity zones namely above the Box Canyon area, the power station area and the Wiesbaden Motel area. From these low zones it is surmised that the springs are related to a complex fault system which serves as a conduit for the deep circulation of ground waters through the system.

The 1980-1982 Geothermal Resource Assessment Program in Washington  

DOE Green Energy (OSTI)

Since 1978, the Division of Geology and Earth Resources of the Washington Department of Natural Resources has participated in the U.S. Department of Energy's (USDOE) State-Coupled Geothermal Resource Program. Federal and state funds have been used to investigate and evaluate the potential for geothermal resources, on both a reconnaissance and area-specific level. Preliminary results and progress reports for the period up through mid-1980 have already been released as a Division Open File Report (Korosec, Schuster, and others, 1981). Preliminary results and progress summaries of work carried out from mid-1980 through the end of 1982 are presented in this report. Only one other summary report dealing with geothermal resource investigations in the state has been published. An Information Circular released by the Division (Schuster and others, 1978) compiled the geology, geochemistry, and heat flow drilling results from a project in the Indian Heaven area in the south Cascades. The previous progress report for the geothermal program (Korosec, Schuster, and others, 1981) included information on temperature gradients measured throughout the state, heat flow drilling in the southern Cascades, gravity surveys for the southern Cascades, thermal and mineral spring investigations, geologic mapping for the White Pass-Tumac Mountain area, and area specific studies for the Camas area of Clark County and Mount St. Helens. This work, along with some additional studies, led to the compilation of the Geothermal Resources of Washington map (Korosec, Kaler, and others, 1981). The map is principally a nontechnical presentation based on all available geothermal information, presented as data points, tables, and text on a map with a scale of 1:500,000.

Prospects and problems of development of geothermal resources of Russia  

SciTech Connect

This article discusses the pros and cons of geothermal energy source development in the Russian Federation. It estimates the geothermal reserves in each area of the Federation and presents the data in terms of tons of conventional fuels. Across the region, the average specific density exceeds 2,000,000 tons of conventional fuel per cubic kilometer. In the administrative regions of central Russia, the geothermal reserves are estimated to range from 160 years to 4200 years. The economic feasibility of developing these resources in the administrative regions is also explored, and it is concluded that the geothermal heat source is a source of hot water that is far superior to the conventional electric boiler-house source.

Economics of geothermal electricity generation from hydrothermal resources  

DOE Green Energy (OSTI)

The most important factors affecting the economics of geothermal electricity production are the wellhead temperature or enthalpy, the well flow rate, and the cost of the wells. The capital cost of the powerplant is significant, but not highly sensitive to these resource characteristics. The optimum geothermal plant size will remain small, usually in the 50-100 MWe range. Therefore, the opportunities for achieving significant cost reductions through ''economies of scale'' are small. The steam and binary power cycles are closely competitive; the binary cycle appears better when the brine temperature is below 200-230/sup 0/C, and the flashed steam cycle appears better above this range. Geothermal electricity production is capital intensive; over 75 percent of the generation costs are fixed costs related to capital investment. Technological advances are needed to reduce costs from marginal geothermal resources and thus to stimulate geothermal energy development. Significant reduction in power costs would be achieved by reducing well drilling costs, stimulating well flow rates, reducing powerplant capital costs, increasing powerplant efficiency and utilization, and developing more effective exploration techniques for locating and assessing high-quality resources.

Geothermal energy resource assessment of parts of Alaska. Final report  

DOE Green Energy (OSTI)

The central Seward Peninsula was the subject of a geological, geophysical and geochemical reconnaissance survey during a 30-day period in the summer of 1980. The survey was designed to investigate the geothermal energy resource potential of this region of Alaska. A continental rift system model was proposed to explain many of the Late Tertiary-to-Quaternary topographic, structural, volcanic and geothermal features of the region. Geologic evidence for the model includes normal faults, extensive fields of young alkalic basalts, alignment of volcanic vents, graben valleys and other features consistent with a rift system active from late Miocene time to the present. Five traverses crossing segments of the proposed rift system were run to look for evidence of structure and geothermal resources not evident from surface manifestation. Gravity, helium and mercury soil concentrations were measured along the traverses. Seismic, resistivity, and VLF studies are presented.

Market penetration analysis for direct heat geothermal energy applications  

SciTech Connect

This study is concerned with the estimation of the National geothermal market potential and penetration in direct heat applications for residences and certain industry segments. An important aspect of this study is that the analysis considers both known and anticipated goethermal resources. This allows for an estimation of the longer-range potential for geothermal applications. Thus the approach and results of this study provide new insights and valuable information not obtained from more limited, site-specific types of analyses. Estimates made in this study track geothermal market potential and projected penetration from the present to the year 2020. Private sector commercialization of geothermal energy over this period requires assistance in the identification of markets and market sizes, potential users, and appropriate technical applications.

Geothermal brines and sludges: a new resource  

DOE Green Energy (OSTI)

Development of cost efficient biochemical processes for the treatment of geothermal brines and sludges is the main thrust of a major R&D effort at Brookhaven National Laboratory (BNL). This effort has led to the design of an environmentally acceptable, technically and economically feasible new technology which converts geothermal wastes into products with significant commercial potential. These include valuable metals recovery with a metal extraction and recovery efficiency of better then 80% over short periods of time (5-25 hours). The new technology also yields valuable salts, such as potassium chloride and generates high quality pigment free silica. The basic technology is versatile and can, with slight modifications, be used in the treatment of hypersaline as well as low salinity brines and sludges. Concurrently traces of toxic metals, including radium are removed to levels which are within regulatory limits. The current status of the new biochemical technology will be discussed in this paper.

Regional Systems Development for Geothermal Energy Resources Pacific Region (California and Hawaii). Task 3: water resources evaluation. Topical report  

DOE Green Energy (OSTI)

The fundamental objective of the water resources analysis was to assess the availability of surface and ground water for potential use as power plant make-up water in the major geothermal areas of California. The analysis was concentrated on identifying the major sources of surface and ground water, potential limitations on the usage of this water, and the resulting constraints on potentially developable electrical power in each geothermal resource area. Analyses were completed for 11 major geothermal areas in California: four in the Imperial Valley, Coso, Mono-Long Valley, Geysers-Calistoga, Surprise Valley, Glass Mountain, Wendel Amedee, and Lassen. One area in Hawaii, the Puna district, was also included in the analysis. The water requirements for representative types of energy conversion processes were developed using a case study approach. Cooling water requirements for each type of energy conversion process were estimated based upon a specific existing or proposed type of geothermal power plant. The make-up water requirements for each type of conversion process at each resource location were then estimated as a basis for analyzing any constraints on the megawatts which potentially could be developed.

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.

Climatology of air quality of Long Valley Geothermal Resource Area  

DOE Green Energy (OSTI)

The Long Valley Known Geothermal Resource Area is one of the more promising regions for development of a large-scale geothermal energy center. This report discusses the climatology and air quality of the area. Details are given on the temperatures, temperature inversions, and winds. Estimates are presented for the present air quality and future air quality during and following development of the resource area. Also discussed are project impact from added pollutants, noise, and precipitation augmentation. The major deleterious effects from development of the Long Valley Geothermal Resource Area appear to be due to increased dust loading during and following construction, and noise from production testing and potential well blowouts. Increased pollution from release of hydrogen sulfide and other pollutants associated with hot water geothermal wells seems to present no problems with regard to surrounding vegetation, potential contamination of Lake Crowley, and odor problems in nearby communities. Precipitation augmentation will probably increase the water level of Lake Crowley, at the expense of possible additional fogging and icing of nearby highways.

Utah State Prison Space Heating with Geothermal Heat - Resource Assessment Report Crystal Hot Springs Geothermal Area  

DOE Green Energy (OSTI)

Reported herein is a summary of work conducted under the Resource Assessment Program-Task 2, for the Utah State Prison Geothermal Space Heating Project at Crystal Hot Springs, Draper, Utah. Assessment of the geothermal resource in and around the Utah State Prison property began in october of 1979 with an aeromagnetic and gravity survey. These tasks were designed to provide detailed subsurface structural information in the vicinity of the thermal springs so that an informed decision as to the locations of test and production holes could be made. The geophysical reconnaissance program provided the structural details needed to focus the test drilling program on the most promising production targets available to the State Prison. The subsequent drilling and well testing program was conducted to provide information to aid fin the siting and design of a production well and preliminary design activities. As part of the resource assessment portion of the Utah State Prison Geothermal Project, a program for periodic geophysical monitoring of the Crystal Hot Springs resource was developed. The program was designed to enable determination of baseline thermal, hydraulic, and chemical characteristics in the vicinity of Crystal Hot Springs prior to production and to provide a history of these characteristics during resource development.

Since available literature dealing with employment involved in the geothermal sector appeared relatively outdated, unduly focused on certain activities of the industry (e.g. operation and maintenance of geothermal power plants) or poorly reliable, GEA, in consultation with the DOE, decided to conduct a new employment survey to provide better answers to these questions. The main objective of this survey is to assess and characterize the current workforce involved in geothermal activities in the US. Several initiatives have therefore been undertaken to reach as many organizations involved in geothermal activities as possible and assess their current workforce. The first section of this document describes the methodology used to contact the companies involved in the geothermal sector. The second section presents the survey results and analyzes them. This analysis includes two major parts. The first part analyzes the survey responses, presents employment numbers that were captured and describes the major characteristics of the industry that have been identified. The second part of the analysis estimates the number of workers involved in companies that are active in the geothermal business but did not respond to the survey or could not be reached. Preliminary conclusions and the study limits and restrictions are then presented. The third section addresses the potential employment impact related to manufacturing and construction of new geothermal power facilities. Indirect and induced economic impacts related with such investment are also investigated.

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.

Geothermal resource area 3: Elko County. Area development plan  

DOE Green Energy (OSTI)

Geothermal Resource Area 3 includes all of the land in Elko County, Nevada. There are in excess of 50 known thermal anomalies in this area. Several of the more major resources have been selected for detailed description and evaluation in this Area Development Plan. The other resources are considered too small, too low in temperature, or too remote to be considered for development in the near future. Various potential uses of the energy found at each of the studied resource sites in Elko County were determined after evaluating the area's physical characteristics; the land ownership and land use patterns; existing population and projected growth rates; transportation facilities and energy requirements. These factors were then compared with resource site specific data to determine the most likely uses of the resource. The uses considered in this evaluation were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories several subdivisions were considered separately. It was determined that several of the geothermal resources evaluated in the Area Development Plan could be commercially developed. The potential for development for the seven sites considered in this study is summarized.

Direct application of east coast geothermal resources in a frozen food plant. Final report  

DOE Green Energy (OSTI)

The technical and economic viability of retrofitting an existing frozen food plant in Salisbury, Maryland to utilize the anticipated geothermal resources in that area was evaluated, via a budgetary level design and cost estimating analysis. Based on predicted reservoir data, a design concept was developed from production well through the plant to final brine disposal. A parametric analysis of capital and operating costs was performed which covered the range of geothermal design data developed. Relevant social, financial, environmental, legal, and regulatory institutional relationships were examined and ways to eliminate any barriers they presented against the proposed application were explored. Based on results from the other tasks, the existing DOE East Coast Geothermal Development Plan was evaluated and possible alterations were proposed. (MHR)

Reconnaissance geothermal resource assessment of 40 sites in California  

DOE Green Energy (OSTI)

Results are set forth for a continuing reconnaissance-level assessment of promising geothermal sites scattered through California. The studies involve acquisition of new data based upon field observations, compilation of data from published and unpublished sources, and evaluation of the data to identify areas suitable for more intensive area-specific studies. Forty sites were chosen for reporting on the basis of their relative potential for development as a significant resource. The name and location of each site is given, and after a brief synopsis, the geothermal features, chemistry, geology, and history of the site are reported. Three sites are recommended for more detailed study on the basis of potential for use by a large number of consumers, large volume of water, and the likelihood that the resource underlies a large area.

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.

Hawaii Geothermal Resource Assessment Program: western state cooperative direct heat resource assessment, Phase I. Final report  

DOE Green Energy (OSTI)

A regional geothermal resource assessment has been conducted for the major islands in the Hawaiian chain. The assessment was made through the compilation and evaluation of the readily accessible geological, geochemical, and geophysical data for the Hawaiian archipelago which has been acquired during the last two decades. The geologic criteria used in the identification of possible geothermal reservoirs were: age and location of most recent volcanism on the island and the geologic structure of each island. The geochemical anomalies used as traces for geothermally altered ground water were: elevated silica concentrations and elevated chloride/magnesium ion ratios. Geophysical data used to identify subsurface structure which may have geothermal potential were: aeromagnetic anomalies, gravity anomalies, and higher than normal well and basal spring discharge temperatures. Geophysical and geochemical anomalies which may be the result of subsurface thermal effects have been identified on the islands of Hawaii, Maui, Molokai and Oahu.

Contract No. DE-AC36-99-GO10337Geothermal The Energy Under Our Feet Geothermal Resource Estimates for the  

E-Print Network (OSTI)

The Earth houses a vast energy supply in the form of geothermal resources. Domestic resources are equivalent to a 30,000-year energy supply at our current rate for the United States! In fact, geothermal energy is used in all 50 U.S. states today. But geothermal energy has not reached its full potential as a clean, secure energy alternative because of issues with resources, technology, historically low natural gas prices, and public policies. These issues affect the economic competitiveness of geothermal energy On May 16, 2006, the National Renewable Energy Laboratory (NREL) in Golden, Colorado hosted a geothermal resources workshop with experts from the geothermal community. The purpose of the workshop was to re-examine domestic geothermal resource estimates. The participating experts were organized into five working groups based on their primary area of expertise in the following types of geothermal resource

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.

Geothermal resource assessment for North Dakota. Final Report  

SciTech Connect

Temperatures in four geothermal aquifers, inyan Kara (Cretaceous), Mission Canyon (Mississippian), Duperow (Devonian), and Red River (Ordovician) are in the range for low and moderate temperature geothermal resources within an area of about 130,000 km{sup 2} in North Dakota. The accessible resource base is 13,500 x 10{sup 18} J., which, assuming a recovery factor of 0.001, may represent a greater quantity of recoverable energy than is present in the basin in the form of petroleum. A synthesis of heat flow, thermal conductivity, and stratigraphic data was found to be significantly more accurate in determining formation temperatures than the use of linear temperature gradients derived from bottom hole temperature data. The thermal structure of the Williston Basin is determined by the thermal conductivities of four principal lithologies: Tertiary silts and sands (1.6 W/m/K), Mesozoic shales (1.2 W/m/K), Paleozoic limestones (3.2 W/m/K), and Paleozoic dolomites (3.5 W/m/K). The stratigraphic placement of these lithologies leads to a complex, multi-component geothermal gradient which precludes use of any single component gradient for accurate determination of subsurface temperatures.

A description is given of the computer program, GEOCOST, and its application to some analyses of the economics of geothermal energy. GEOCOST combines both technical and economic factors into one systematic cost accounting framework. The program, which simulates production of electricity from most types of geothermal resources, is composed of two parts: a reservoir model which simulates the costs associated with the exploration, development, and operation of a geothermal reservoir; and a power-plant model which simulates the costs associated with the design, construction, and operation of the power plant. The costs from the reservoir model become the energy supply costs to the power plant. The combined reservoir and power plant models represent the complete energy production system. (LBS)

With the exception of Sand Springs in Williamstown, Massachusetts, there are no identifiable hydrothermal geothermal resources in the New England region. The radioactive plutons of the White Mountains of New Hampshire do not, apparently, contain sufficient stored heat to make them a feasible target for an induced hydrothermal system such as exists at Fenton Hill near Los Alamos, New Mexico. The only potential source of low grade heat is the large volume of ground water contained within the unconsolidated sediments related to the Pleistocene glaciation of the region. During the course of the survey an unusual and unexplained thermal anomaly was discovered in St. Johnsbury, Vermont, which is described.

Report of the State Geothermal Resources Task Force, State of California  

DOE Green Energy (OSTI)

The State Geothermal Resources Task Force has investigated the status of geothermal resources and development in California and in this report offers recommendations for overcoming obstacles facing increased utilization of this significant natural resource. For the most part, these recommendations are short-term solutions to immediate problems and would not radically change the roles of governmental agencies currently regulating geothermal development. The Task Force concludes that geothermal operations have been hindered by the lack of a statewide policy on geothermal development. This has resulted in instances where industry has been forced to comply with conflicting governmental policies toward geothermal energy development and environmental protection. The Task Force therefore recommends legislation establishing a statewide policy to encourage geothermal development consistent with environmental quality standards. In addition to geothermal resources suitable for the production of electrical power, California has extensive undeveloped hot water reservoirs suitable for direct thermal applications. The Energy Resources Conservation and Development Commission and the US Geological Survey have concluded that these resources, if developed, could make a significant contribution to satisfying California's energy needs. The Task Force therefore recommends establishing a statewide policy to encourage the use of non-electric hot water geothermal resources for commercial and non-commercial uses where the development is consistent with environmental quality concerns.

Tables of co-located geothermal-resource sites and BLM Wilderness Study Areas  

DOE Green Energy (OSTI)

Matched pairs of known geothermal wells and springs with BLM proposed Wilderness Study Areas (WSAs) were identified by inspection of WSA and Geothermal resource maps for the states of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. A total of 3952 matches, for geothermal sites within 25 miles of a WSA, were identified. Of these, only 71 (1.8%) of the geothermal sites are within one mile of a WSA, and only an additional 100 (2.5%) are within one to three miles. Approximately three-fourths of the matches are at distances greater than ten miles. Only 12 of the geothermal sites within one mile of a WSA have surface temperatures reported above 50/sup 0/C. It thus appears that the geothermal potential of WSAs overall is minimal, but that evaluation of geothermal resources should be considered in more detail for some areas prior to their designation as Wilderness.

Reconnaissance of geothermal resources of Los Angeles County, California  

DOE Green Energy (OSTI)

Thermal waters produced from large oil fields are currently the most important geothermal resources in Los Angeles County. Otherwise, the County does not appear to have any large, near-surface geothermal resources. The oil fields produce thermal water because of both the moderate depths of production and normal to above-normal geothermal gradients. Gradients are about 3.0-3.5/sup 0/C/100 meters in the Ventura Basin and range from that up to about 5.5-6.0/sup 0/C/100 meters in the Los Angeles Basin. The hottest fields in the County are west of the Newport-Inglewood Structural Zone. The Los Angeles Basin has substantially more potential for uses of heat from oil fields than does the Ventura Basin because of its large fields and dense urban development. Produced fluid temperatures there range from ambient air to boiling, but most are in the 100-150/sup 0/F range. Daily water production ranges from only a few barrels at some fields to over a million barrels at Wilmington Oil Field; nearly all fields produce less than 50,000 barrels/day. Water salinity generally ranges from about 15,000-35,000 mg/liter NaCl. Fields with the most promise as sources of heat for outside applications are Wilmington, Torrance, Venice Beach, and Lawndale. The centralized treatment facilities are the most favorable sites for extraction of heat within the oil fields. Because of the poor water quality heat exchangers will likely be required rather than direct circulation of the field water to users. The best sites for applications are commercial-industrial areas and possibly institutional structures occupied by large numbers of people.

Preliminary definition of the geothermal resources potential of Pennsylvania  

DOE Green Energy (OSTI)

Pennsylvania has a diverse geology. A small portion of the northeastern corner of the state is covered by Atlantic Coastal Plains sediments. To the northwest metamorphic rocks in the Piedment, Blue Ridge and Reading Prong areas are exposed. Triassic basine cut across portions of the Piedmont. The western portion of the state is underlain by Paleozoic sediments of the folded Appalachians and the Appalachian or Allegheny Basin. Crystalline rocks are limited to the metamorphic and igneous rocks of the Piedmont, Blue Ridge, and Reading Prong and to Triassic diabase intrusives. Potential for geothermal resources in Pennsylvania appear to be limited to small hydrothermal systems associated with deep convection in the folded Appalachians or deep sources in the Appalachian Basin. Heat flow measurements and temperature gradients from oil and gas wells suggest normal continental heat flow in Pennsylvania. Under such conditions temperatures of about 200{sup 0}C (392{sup 0}F) are possible near the base of the sedimentary section (about 9 km, 30,000 feet). Warm springs are not as common in Pennsylvania as they are to the south in West Virginia and Virginia. Apparently the structure does not facilitate convective circulation. Geothermal resources in Pennsylvania appear to be restricted to those available in an area of normal temperature gradients.

Geothermal resource assessment of the Animas Valley, Colorado. Resource Series 17  

DOE Green Energy (OSTI)

The Colorado Geological Survey, has been engaged in assessing the nature and extent of Colorado's geothermal resources. The program has included geologic and hydrogeologic reconnaissance, and geophysical and geochemical surveys. In the Animas Valley, in southwestern Colorado, two groups of thermal springs exist: Pinkerton Springs to the north, and Tripp-Trimble-Stratten Springs about 5 miles (8.1 Km) south of Pinkerton. The geothermal resources of the Animas Valley were studied. Due to terrain problems in the narrow valley, a soil mercury survey was conducted only at Tripp-Trimble Stratten, while an electrical D.C. resistivity survey was limited to the vicinity of Pinkerton. Although higher mercury values tended to be near a previously mapped fault, the small extent of the survey ruled out conclusive results. Consistent low resistivity zones interpreted from the geophysical data were mapped as faults near Pinkerton, and compared well with aerial photo work and spring locations. This new information was added to reconnaissance geology and hydrogeology to provide several clues regarding the geothermal potential of the valley. Hydrothermal minerals found in faults in the study area are very similar to ore mined in a very young mountain range, nearby. Groundwater would not need to circulate very deeply along faults to attain the estimated subsurface temperatures present in the valley. The water chemistry of each area is unique. Although previously incompletely manned, faulting in the area is extensive. The geothermal resources in the Animas Valley are fault controlled. Pinkerton and Tripp-Trimble-Stratten are probably not directly connected systems, but may have the same source at distance. Recharge to the geothermal system comes from the needle and La Plata Mountains, and the latter may also be a heat source. Movement of the thermal water is probably primarily horizontal, via the Leadville Limestone aquifer.

Preliminary definition of the geothermal resources potential of West Virginia  

DOE Green Energy (OSTI)

Most of West Virginia is underlain by Paleozoic sedimentary rocks. Crystalline rocks are limited to two areas: a small area in the Harpers Ferry region and some basic intrusives and extrusives in Pendleton County. In the Valley and Ridge province the rocks are folded and faulted. The deformation appears to be confined to the sediments overlying the crystalline basement. The Appalachian Basin is characterized by moderately dipping sediments which may reach ticknesses of 7600 meters (25,000 feet) in eastern West Virginia. The 38th parallel fracture zone may extend through West Virginia and serve to localize geothermal resources. Heat flow in West Virginia appears to be rather uniform and in the range of 1.12 to 1.26 heat flow units. Bottomhole temperatures from oil and gas tests show no abnormally hot spots. Warm springs are limited to the eastern portion of West Virginia in the folded Appalachians and appear to be located on the flanks of anticlines at topographic lows. Geothermometry suggests subsurface temperatures in the 45 to 65{sup 0}C (113 to 149{sup 0}F) range. The Appalachian Basin provides a thick sequence of rocks with normal geothermal gradient (18.2{sup 0}C/kilometer, 1{sup 0}F/100 feet). High temperatures are expected at great depths, but production rates are likely to be low. Several oil and gas tests in West Virginia have encountered pressures about twice the normal pressure expected at the depth. However, the overpressured zones appear to be of small extent.

Geothermal resource potential of the Socorro Area, New Mexico  

DOE Green Energy (OSTI)

This report provides a regional synthesis of geology, geochemistry, hydrology and geophysical data for the Socorro, New Mexico, area. It is based principally on extensive drill-hole data supplied by, and proprietary to, Gulf Mineral Resources Company and Sunoco Energy Development Co. These temperature-gradient and heat-flow data are integrated with older gradient and heat-flow data, groundwater chemistry, studies of local seismicity, regional and local geologic mapping, and other data. This synthesis yields a revised estimate of the geothermal energy potential for the Socorro area. it should be recalled that attention has been focused on Socorro and vicinity because of reported high heat flow and probable magmatic bodies within the shallow crust. Some 20 man-days of effort have gone into this study, exclusive of time spent earlier in logging temperature gradients and studying drill-hole cuttings.

Resource investigation of low- and moderate-temperature geothermal areas in San Bernardino, California  

SciTech Connect

The California Division of Mines and Geology (CDMG) selected the San Bernardino area for detailed geothermal resource investigation because the area was known to contain promising geothermal resource sites, the area contained a large population center, and the City of San Bernardino had expressed serious interest in developing the area's geothermal resource. Ninety-seven geothermal wells and springs were identified and plotted on a compiled geologic map of the 40-square-mile study area. These wells and springs were concentrated in three distinguishable resource areas: Arrowhead Hot Springs, South San Bernardino, and Harlem Hot Springs--in each of which detailed geophysical, geochemical, and geological surveys were conducted. The Arrowhead Hot Springs geothermal area lies just north of the City of San Bernardino in the San Bernardino Mountains astride a shear zone (offshoot of the San Andreas fault) in pre-Cambrian gneiss and schist. The Harlem Hot Springs geothermal area, on the east side of the City, and the South San Bernardino geothermal area, on the south side, have geothermal reservoirs in Quaternary alluvial material which overlies a moderately deep sedimentary basin bound on the southwest by the San Jacinto fault (a ground water barrier). Geothermometry calculations suggest that the Arrowhead Hot Springs geothermal area, with a maximum reservoir temperature of 142 C, may have the highest maximum reservoir temperature of the three geothermal areas. The maximum temperature recorded by CDMG in the South San Bernardino geothermal area was 56 C from an artesian well, while the maximum temperature recorded in the Harlem Hot Springs geothermal areas was 49.5 C at 174 meters (570 feet) in an abandoned water well.

Enhancement of existing geothermal resource utilization by cascading to intensive aquaculture  

DOE Green Energy (OSTI)

A demonstration high rate aquaculture production system utilizing a cascaded geothermal resource was designed, constructed and operated to fulfill the objectives of this project. Analysis of the energy and water balances for the system indicated that the addition of an Aquaculture Facility expanded the use of the existing resource. This expanded use in no way affected the up- stream processes. Analysis of the system`s energy and water requirements indicated that the present resource was under-utilized and could be expanded. Energy requirements appeared more limiting than water use, but the existing system could be expanded to a culture volume of 72,000 gal. This system would have a potential production capacity of 93,600 lb/yr with a potential market value of $280,00/yr. Based on the results of this study, the heat remaining in the geothermal fluid from one square foot of operating greenhouse is sufficient to support six gallons of culture water for a high density aquaculture facility. Thus, the over 1.5M ft{sup 2} of existing greenhouse space in New Mexico, has the potential to create an aquaculture industry of nearly 9M gal. This translates to an annual production potential of 11.7M lb with a market value of $35.lM.

The objective was to consolidate and evaluate all geologic, environmental, and legal and institutional information in existing records and files, and to apply a uniform methodology to the evaluation and ranking of sites to allow the making of creditable forecasts of the supply of geothermal energy which could be available in the region over a 20 year planning horizon. A total of 1265 potential geothermal resource sites were identified from existing literature. Site selection was based upon the presence of thermal and mineral springs or wells and/or areas of recent volcanic activity and high heat flow. 250 sites were selected for detailed analysis. A methodology to rank the sites by energy potential, degree of developability, and cost of energy was developed. Resource developability was ranked by a method based on a weighted variable evaluation of resource favorability. Sites were ranked using an integration of values determined through the cost and developability analysis. 75 figs., 63 tabs.

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.

A Resource Assessment Of Geothermal Energy Resources For Converting Deep Gas Wells In Carbonate Strata Into Geothermal Extraction Wells: A Permian Basin Evaluation  

Science Conference Proceedings (OSTI)

Previously conducted preliminary investigations within the deep Delaware and Val Verde sub-basins of the Permian Basin complex documented bottom hole temperatures from oil and gas wells that reach the 120-180C temperature range, and occasionally beyond. With large abundances of subsurface brine water, and known porosity and permeability, the deep carbonate strata of the region possess a good potential for future geothermal power development. This work was designed as a 3-year project to investigate a new, undeveloped geographic region for establishing geothermal energy production focused on electric power generation. Identifying optimum geologic and geographic sites for converting depleted deep gas wells and fields within a carbonate environment into geothermal energy extraction wells was part of the project goals. The importance of this work was to affect the three factors limiting the expansion of geothermal development: distribution, field size and accompanying resource availability, and cost. Historically, power production from geothermal energy has been relegated to shallow heat plumes near active volcanic or geyser activity, or in areas where volcanic rocks still retain heat from their formation. Thus geothermal development is spatially variable and site specific. Additionally, existing geothermal fields are only a few 10s of square km in size, controlled by the extent of the heat plume and the availability of water for heat movement. This plume radiates heat both vertically as well as laterally into the enclosing country rock. Heat withdrawal at too rapid a rate eventually results in a decrease in electrical power generation as the thermal energy is mined. The depletion rate of subsurface heat directly controls the lifetime of geothermal energy production. Finally, the cost of developing deep (greater than 4 km) reservoirs of geothermal energy is perceived as being too costly to justify corporate investment. Thus further development opportunities for geothermal resources have been hindered. To increase the effective regional implementation of geothermal resources as an energy source for power production requires meeting several objectives. These include: 1) Expand (oil and gas as well as geothermal) industry awareness of an untapped source of geothermal energy within deep permeable strata of sedimentary basins; 2) Identify and target specific geographic areas within sedimentary basins where deeper heat sources can be developed; 3) Increase future geothermal field size from 10 km2 to many 100s km2 or greater; and 4) Increase the productive depth range for economic geothermal energy extraction below the current 4 km limit by converting deep depleted and abandoned gas wells and fields into geothermal energy extraction wells. The first year of the proposed 3-year resource assessment covered an eight county region within the Delaware and Val Verde Basins of West Texas. This project has developed databases in Excel spreadsheet form that list over 8,000 temperature-depth recordings. These recordings come from header information listed on electric well logs recordings from various shallow to deep wells that were drilled for oil and gas exploration and production. The temperature-depth data is uncorrected and thus provides the lower temperature that is be expected to be encountered within the formation associated with the temperature-depth recording. Numerous graphs were developed from the data, all of which suggest that a log-normal solution for the thermal gradient is more descriptive of the data than a linear solution. A discussion of these plots and equations are presented within the narrative. Data was acquired that enable the determination of brine salinity versus brine density with the Permian Basin. A discussion on possible limestone and dolostone thermal conductivity parameters is presented with the purpose of assisting in determining heat flow and reservoir heat content for energy extraction. Subsurface maps of temperature either at a constant depth or within a target geothermal reservoir are discusse

GEOCITY: a computer model for systems analysis of geothermal district heating and cooling costs  

DOE Green Energy (OSTI)

GEOCITY is a computer-simulation model developed to study the economics of district heating/cooling using geothermal energy. GEOCITY calculates the cost of district heating/cooling based on climate, population, resource characteristics, and financing conditions. The basis for our geothermal-energy cost analysis is the unit cost of energy which will recover all the costs of production. The calculation of the unit cost of energy is based on life-cycle costing and discounted-cash-flow analysis. A wide variation can be expected in the range of potential geothermal district heating and cooling costs. The range of costs is determined by the characteristics of the resource, the characteristics of the demand, and the distance separating the resource and the demand. GEOCITY is a useful tool for estimating costs for each of the main parts of the production process and for determining the sensitivity of these costs to several significant parameters under a consistent set of assumptions.

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)

Potential growth of electric power production from Imperial Valley geothermal resources  

DOE Green Energy (OSTI)

The growth of geothermal electric power operations in Imperial Valley, California is projected over the next 40 years. With commercial power forecast to become available in the 1980's, the scenario considers three subsequent growth rates: 40, 100, and 250 MW per year. These growth rates, along with estimates of the total resource size, result in a maximum level of electric power production ranging from 1000 to 8000 MW to be attained in the 2010 to 2020 time period. Power plant siting constraints are developed and used to make siting patterns for the 400- through 8000-MW level of power production. Two geothermal technologies are included in the scenario: flashed steam systems that produce cooling water from the geothermal steam condensate and emit noncondensable gases to the atmosphere; and high pressure, confined flow systems that inject the geoghermal fluid back into the ground. An analysis of the scenario is made with regard to well drilling and power plant construction rates, land use, cooling water requirements, and hydrogen sulfide emissions.

Northern California Power Association--Shell Oil Company Geothermal Project No. 2: energy and materials resources  

DOE Green Energy (OSTI)

The potential environmental impact of the energy and material resources expended in site preparation, construction, operation, maintenance, and abandonment of all phases of the Northern California Power Association--Shell Geothermal Project in The Geysers--Calistoga Known Geothermal Resource Area is described. The impact of well field development, operation, and abandonment is insignificant, with the possible exception of geothermal resource depletion due to steam withdrawal from supply wells during operation. The amount of resource renewal that may be possible through reinjection is unknown because of uncertainties in the exact amount of heat available in the steam supply field. Material resources to be used in construction, operation, and abandonment of the power plant and transmission lines are described. Proposed measures to mitigate the environmental impacts from the use of these resources are included. Electric power supply and demand forecasts to the year 2005 are described for the area served by the NCPA.

Geothermal energy and the land resource: conflicts and constraints in The Geysers-Calistoga KGRA  

DOE Green Energy (OSTI)

This study of potential land-related impacts of geothermal power development in The Geysers region focuses on Lake County because it has most of the undeveloped resource and the least regulatory capability. First, the land resource is characterized in terms of its ecological, hydrological, agricultural, and recreational value; intrinsic natural hazards; and the adequacy of roads and utility systems. Based on those factors, the potential land-use conflicts and constraints that geothermal development may encounter in the region are identified and the availability and relative suitability of land for such development is determined. A brief review of laws and powers germane to geothermal land-use regulation is included.

GEOCITY: a computer code for calculating costs of district heating using geothermal resources  

DOE Green Energy (OSTI)

GEOCITY is a computer simulation model developed to study the economics of district heating using geothermal energy. GEOCITY calculates the cost of district heating based on climate, population, resource characteristics, and financing conditions. The principal input variables are minimum temperature, heating degree days, population size and density, resource temperature and distance from load center, and the interest rate. From this input data the model designs the transmission and district heating systems. From this design, GEOCITY calculates the capital and operating costs for the entire system, including the production and disposal of the geothermal water. GEOCITY consists of two major submodels: the geothermal reservoir model and the distribution system model. The distribution system model calculates the cost of heat by simulating the design and the operation of the district heating system. The reservoir model calculates the cost of energy by simulating the discovery, development and operation of a geothermal resource and the transmission of this energy to a distribution center.

The Marysville, Montana, Geothermal Project: Environmental Analysis of the Deep Geothermal Research Well  

DOE Green Energy (OSTI)

The objective of this research project is to investigate a geothermal anomaly of high heat flow discovered in 1969 in central Montana, and to determine how this natural resource might be developed as a source of useful energy. Under Phase I, the natural resource will be explored, drilled, and modeled at an estimated cost of $2,588,935 over a 3-year period. Phase II, depending upon the nature of the heat source, will be developing the resource under a cooperative effort of government and private industry. This environmental analysis is intended to cover the drilling and logging operations noted under Phase I, the only work being undertaken at this time. As can be seen from Figure 1, further tests may be run at this site in later phases of the study. But since the nature of these tests are highly dependent on the results of Phase I, it is not considered productive to speculate on their environmental impact. As is show, however, any later experiments would cover a range of underground experiments, some of which consume water and others which would produce water. Before a meaningful analysis of such work can be written, it will be necessary to analyze the results of Phase I findings.

Multielement geochemical exploration data for the Cove Fort-Sulphurdale Known Geothermal Resource Area, Beaver and Millard counties, Utah  

DOE Green Energy (OSTI)

Multielement geochemical exploration data have been acquired for the Cove Fort-Sulphurdale Known Geothermal Resource Area (KGRA). This was accomplished by analysis of both whole rock and +3.3 specific gravity concentrate samples from cuttings composites collected from shallow rotary drill holes. Areal distributions are reported for arsenic, mercury, lead and zinc. These are elements indicated by previous studies to be broadly zoned around thermal centers in geothermal systems and thus to be useful for selecting and prioritizing drilling targets. Results from this work suggest that reservoir temperature and/or reservoir to surface permeability, and thus possibly overall potential for a geothermal resource, increase northward beneath the approximately 18 square mile area containing shallow drill holes, possibly to beyond the northern limits of the area. The data provide a basis for development of three principal target models for the geothermal system but do not permit prioritization of these models. It is recommended that geochemical, geological, and temperature gradient surveys be expanded northward from the present survey area to more fully define the area which appears to have the best resource potential and to aid prioritization of the target models.

Geothermal feasibility-analysis II for Polo School District No. 29-2, South Dakota  

SciTech Connect

The feasibility of utilizing a low temperature geothermal resource to heat the Polo High School and the community of Polo, consisting of 17 residential homes, 2 public school buildings, 5 commercial establishments, and the St. Liborius Church/School complex is addressed. Depending upon the availability of a water use permit from the South Dakota Department of Natural Resources and the payback period required for this type of project, there is heat energy in the existing geothermal resource to heat the Polo High School or even the entire community of Polo. The chemical analysis of the water indicates that any heat exchangers used should be stainless steel or thick-walled copper and piping should be plastic. An environmental assessment would be required to consider the disposal of geothermal fluid.

Preliminary Technical Risk Analysis for the Geothermal Technologies Program  

DOE Green Energy (OSTI)

This report explains the goals, methods, and results of a probabilistic analysis of technical risk for a portfolio of R&D projects in the DOE Geothermal Technologies Program ('the Program'). The analysis is a task by Princeton Energy Resources International, LLC (PERI), in support of the National Renewable Energy Laboratory (NREL) on behalf of the Program. The main challenge in the analysis lies in translating R&D results to a quantitative reflection of technical risk for a key Program metric: levelized cost of energy (LCOE). This requires both computational development (i.e., creating a spreadsheet-based analysis tool) and a synthesis of judgments by a panel of researchers and experts of the expected results of the Program's R&D.

Geothermal resource area 6: Lander and Eureka Counties. Area development plan  

DOE Green Energy (OSTI)

Geothermal Resource Area 6 includes Lander and Eureka Counties. There are several different geothermal resources ranging in temperature from 70/sup 0/F to in excess of 400/sup 0/F within this two country area. Eleven of these resources are considered major and have been selected for evaluation in this Area Development Plan. The various potential uses of the energy found at each of the 11 resource sites were determined after evaluating the study area's physical characteristics, land ownership and land use patterns, existing population and projected growth rates, and transportation facilities. These were then compared with the site specific resource characteristics. The uses considered were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories certain subdivisions were considered separately. The findings about each of the 11 geothermal sites considered are summarized.

Energy analysis of geothermal-electric systems  

DOE Green Energy (OSTI)

Standard energy analysis was applied to 4 types of geothermal-electric technologies: liquid dominated, hot dry rock, geopressure, and vapor dominated. It was found that all are net energy producers. Expected uncertainties are not large enough to threaten this conclusion. Vapor dominated, the only technology in current commercial use to produce electricity in the US, has the highest energy ratio (13 +- 4). These results for energy ratio are equal to or less than some from other workers. In the case of liquid dominated, environmental control technology has a considerable energy requirement.

Gas Analysis of Geothermal Fluid Inclusions: A New Technology For Geothermal Exploration  

DOE Green Energy (OSTI)

To increase our knowledge of gaseous species in geothermal systems by fluid inclusion analysis in order to facilitate the use of gas analysis in geothermal exploration. The knowledge of gained by this program can be applied to geothermal exploration, which may expand geothermal production. Knowledge of the gas contents in reservoir fluids can be applied to fluid inclusion gas analysis of drill chip cuttings in a similar fashion as used in the petroleum industry. Thus the results of this project may lower exploration costs both in the initial phase and lower drill hole completion costs. Commercial costs for fluid inclusion analysis done on at 20 feet intervals on chip samples for 10,000 ft oil wells is about $6,000, and the turn around time is a few weeks.

Site-specific analysis of hybrid geothermal/fossil power plants  

DOE Green Energy (OSTI)

The results of an analytical effort to determine the cost effectiveness of hybrid geothermal/fossil-fuel electrical-power generating stations. The analysis is directed at combining hydrothermal and coal energy in a Rankine steam cycle, for electrical power generation for the City of Burbank, California. This effort develops a methodology for hybrid power-plant cost analysis so that preliminary plant designs can be optimized as a function of specific site conditions and characteristics. It also defines cost-optimized site-specific plant designs for four potential sites: Roosevelt Hot Springs, Utah, Coso Thermal Area, California, East Mesa, California, and Long Valley, California. These optimized designs are compared for the costs, geothermal-resource utilization, and fossil fuel saved. The results indicate that development of geothermal resources to support a hybrid power plant are favorable for at least two of the four sites.

Geothermal energy in the western United States and Hawaii: Resources and projected electricity generation supplies. [Contains glossary and address list of geothermal project developers and owners  

DOE Green Energy (OSTI)

Geothermal energy comes from the internal heat of the Earth, and has been continuously exploited for the production of electricity in the United States since 1960. Currently, geothermal power is one of the ready-to-use baseload electricity generating technologies that is competing in the western United States with fossil fuel, nuclear and hydroelectric generation technologies to provide utilities and their customers with a reliable and economic source of electric power. Furthermore, the development of domestic geothermal resources, as an alternative to fossil fuel combustion technologies, has a number of associated environmental benefits. This report serves two functions. First, it provides a description of geothermal technology and a progress report on the commercial status of geothermal electric power generation. Second, it addresses the question of how much electricity might be competitively produced from the geothermal resource base. 19 figs., 15 tabs.

Unalaska geothermal exploration project. Electrical power generation analysis. Final report  

DOE Green Energy (OSTI)

The objective of this study was to determine the most cost-effective power cycle for utilizing the Makushin Volcano geothermal resource to generate electricity for the towns of Unalaska and Dutch Harbor. It is anticipated that the geothermal power plant would be intertied with a planned conventional power plant consisting of four 2.5 MW diesel-generators whose commercial operation is due to begin in 1987. Upon its completion in late 1988, the geothermal power plant would primarily fulfill base-load electrical power demand while the diesel-generators would provide peak-load electrical power and emergency power at times when the geothermal power plant would be partially or completely unavailable. This study compares the technical, environmental, and economic adequacy of five state-of-the-art geothermal power conversion processes. Options considered are single- and double-flash steam cycles, binary cycle, hybrid cycle, and total flow cycle.

Geothermal resource areas database for monitoring the progress of development in the United States  

DOE Green Energy (OSTI)

The Geothermal Resource Areas Database (GRAD) and associated data system provide broad coverage of information on the development of geothermal resources in the United States. The system is designed to serve the information requirements of the National Progress Monitoring System. GRAD covers development from the initial exploratory phase through plant construction and operation. Emphasis is on actual facts or events rather than projections and scenarios. The selection and organization of data are based on a model of geothermal development. Subjects in GRAD include: names and addresses, leases, area descriptions, geothermal wells, power plants, direct use facilities, and environmental and regulatory aspects of development. Data collected in the various subject areas are critically evaluated, and then entered into an on-line interactive computer system. The system is publically available for retrieval and use. The background of the project, conceptual development, software development, and data collection are described here. Appendices describe the structure of the database in detail.

Lawrence Livermore Laboratory (LLL) is studying ways in which the environmental quality of The Geysers-Calistoga known geothermal resources area may be protected from any significant harmful consequences of future geothermal development. The LLL study includes the effects of development on air and water quality, geology, the ecosystem, socioeconomics, and noise. The Geothermal Resource Impact Projection Study (GRIPS) has grants to undertake similar work. On 28 and 29 November 1977, LLL and GRIPS jointly sponsored a workshop at Sonoma State College at which knowledgeable earth scientists presented their views on the potential geological hazards of geothermal development. The workshop produced recommendations for studies in geological mapping, slope stability, subsidence, seismicity, and groundwater hydrology. These recommendations will be evaluated along with other considerations and in conjunction with the other subjects of the LLL study. The results of the study will be contained in a preplanning report of final recommendations to the Department of Energy.

The costs of residential heating throughout the United States using conventional, solar, and geothermal energy were determined under current and projected conditions. These costs are very sensitive to location - being dependent on the local prices of conventional energy supplies, local solar insolation, cimate, and the proximity and temperature of potential geothermal resources. The sharp price increases in imported fuels during 1979 and the planned decontrol of domestic oil and natural gas prices have set the stage for geothermal and solar market penetration in the 1980's.

Data and analysis methods were gathered from the petroleum, geothermal, and hydrological literature. The data sets examined include: Wairakei, New Zealand -141 wells; Cerro Prieto, Mexico - 18 wells; The Geysers, USA - 27 wells; Larderello, Italy - 9 wells and groups; Matsukawa and Otake, Japan - 8 wells; and Olkaria, Kenya - 1 well. The analysis methods tested were; Arps's equations, Fetkovich type curves, Slider's method for Arps, Gentry's method for Arps, Gentry's and McCray's method, other type curves, P/z vs. Q method, Coats' influence function method, and Bodvarsson's Linearized Free Surface Green's Function method. The conclusions are: (1) The exponential equation fit is satisfactory for geothermal data. (2) The hyperbolic equation should be used only if the data fit well on a hyperbolic type curve. (3) The type curve methods are useful if the data are not too scattered. They work well for vapor dominated systems and poorly for liquid dominated systems. (4) Coats' influence function method can be used even with very scattered data. (5) Bodvarsson's method is still experimental but it shows much promise as a useful tool.

Geothermal resource base of the world: a revision of the Electric Power Research Institute's estimate  

DOE Green Energy (OSTI)

Review of the Electric Power Research Institute's (EPRI) method for calculating the geothermal resource base of a country shows that modifications are needed for several of the assumptions used in the calculation. These modifications include: (1) separating geothermal belts into volcanic types with a geothermal gradient of 50{sup 0}C/km and complex types in which 80% of the area has a temperature gradient of 30{sup 0}C/km and 20% has a gradient of 45{sup 0}C/km, (2) using the actual mean annual temperature of a country rather than an assumed 15{sup 0}C average ambient temperature, and (3) making separate calculations for the resource stored in water/brine and that stored in rock. Comparison of this method (Revised EPRI) for calculating a geothermal resource base with other resource base estimates made from a heat flow map of Europe indicates that the technique yields reasonable values. The calculated geothermal resource bases, stored in water and rock to a depth of 5 km, for each country in the world are given. Approximately five times as much energy is stored in rock as is stored in water.

Low-temperature geothermal resource and stratigraphy of portions of Yakima County, Washington  

DOE Green Energy (OSTI)

The low-temperature geothermal resource of portions of Yakima County, south-central Washington, is defined by several least squares linear regression analyses of bottom-hole temperature and depth data. Bottom-hole temperature and depth data were separated into fourteen well data groups based on geographic proximity, land slope azimuth, and position within the regional ground-water flow system. The depths of these wells range from over 50m to almost 600m. The regression analyses of these well data groups indicate that the projected land-surface temperature and geothermal gradient range from 10.6 to 14.0/sup 0/C and from 24.9 to 52.2/sup 0/C/km, respectively. Stratigraphic correlation diagrams developed from borehole geophysical and lithologic logs are given for localities within the lower Yakima, Black Rock, Moxee, Ahtanum, Cowiche, and Naches valleys. These correlation diagrams are combined with their respective borehole temperature logs and well data group predicted temperature curves to assess the validity of the regression analyses and to determine aquifer locations, temperatures, and directions of intra-borehole flow. A regression analysis of data from wells of south-central Washington with bottom-hole depths of over 700m to almost 3km suggests that the projected land-surface temperature and geothermal gradient of this depth interval are 21.8/sup 0/C and 31.3/sup 0/C/km, respectively. The depth to the 100/sup 0/C isotherm is approximately 2513m.

The purpose was to provide the Department of energy's Division of Geothermal Energy with information by which to judge whether to continue development of the Total Flow system. Results indicate that the Total Flow and double flash systems have capital costs of $1,135 and $1,026 /kW with energy costs of 40.9 and 39.7 mills/kW h respectively. The Total Flow and double flash systems are not distinguishable on a cost basis alone; the multistage flash binary system, with capital cost of $1,343 /kW and energy cost of 46.9 mills/kW h, is significantly more expensive. If oil savings are considered in the total analysis, the Total Flow system could save 30% more oil than the double flash system, $3.5 billion at 1978 oil prices.

Applications of geothermal resources in the evaporation and crystallization industry. Final report, September 1976--October 1977  

DOE Green Energy (OSTI)

The objective in this study was to determine the technical and economic feasibility of using low-temperature geothermal energy (hot brines) in place of steam from conventional sources in the evaporation and crystallization industry. A survey of major industries was carried out in order to choose three industries that were significant users of energy, could utilize geothermal brine, and demonstrate the broad range of industrial evaporation and crystallization operations. The selected industries were the preserved fruit and vegetable, sugar and confectionary products, and chemical industries. From among each of the selected industries, an example case was chosen for technical and economic evaluation. This evaluation included use of the ''feed-and-bleed'' process for energy extraction from the low-temperature geothermal brine. This process was chosen as the best process to use because it provides one of the most efficient means of utilizing geothermal brine in evaporation/crystallization operations. This study concludes that, under certain conditions, geothermal energy could be used economically in the evaporation and crystallization industry. The factors that would most affect cost include geothermal resource characteristics (well flow, temperature, and distance of transportation); the energy extraction process chosen (the feed-and-bleed process uses the least amount of brine); and the duration of the evaporation/crystallization process. A program to aid in implementing the use of geothermal energy is included.

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.

American Recovery and Reinvestment Act (ARRA) FEMP Technical Assistance for Geothermal Resource Evaluation Projects  

DOE Green Energy (OSTI)

The purpose of this document is to report on the evaluation of geothermal resource potential on and around three different United States (U. S.) Air Force Bases (AFBs): Nellis AFB and Air Force Range (AFR) in the State of Nevada (see maps 1 and 5), Holloman AFB in the State of New Mexico (see map 2), and Mountain Home AFB in the State of Idaho (see map 3). All three sites are located in semi-arid parts of the western U. S. The U. S. Air Force, through its Air Combat Command (ACC) located at Langley AFB in the State of Virginia, asked the Federal Energy Management Program (FEMP) for technical assistance to conduct technical and feasibility evaluations for the potential to identify viable geothermal resources on or around three different AFBs. Idaho National Laboratory (INL) is supporting FEMP in providing technical assistance to a number of different Federal Agencies. For this report, the three different AFBs are considered one project because they all deal with potential geothermal resource evaluations. The three AFBs will be evaluated primarily for their opportunity to develop a geothermal resource of high enough quality grade (i.e., temperature, productivity, depth, etc.) to consider the possibility for generation of electricity through a power plant. Secondarily, if the resource for the three AFBs is found to be not sufficient enough for electricity generation, then they will be described in enough detail to allow the base energy managers to evaluate if the resource is suitable for direct heating or cooling. Site visits and meetings by INL personnel with the staff at each AFB were held in late FY-2009 and FY-2010. This report provides a technical evaluation of the opportunities and challenges for developing geothermal resources on and around the AFBs. An extensive amount of literature and geographic information was evaluated as a part of this assessment. Resource potential maps were developed for each of the AFBs.

Revisiting the 'Buy versus Build' Decision for Publicly Owned Utilities in California Considering Wind and Geothermal Resources  

DOE Green Energy (OSTI)

The last two decades have seen a dramatic increase in the market share of independent, nonutility generators (NUGs) relative to traditional, utility-owned generation assets. Accordingly, the ''buy versus build'' decision facing utilities--i.e., whether a utility should sign a power purchase agreement (PPA) with a NUG, or develop and own the generation capacity itself--has gained prominence in the industry. Very little of this debate, however, has focused specifically on publicly owned electric utilities, and with few exceptions, renewable sources of supply have received similarly scant attention. Contrary to historical treatment, however, the buy versus build debate is quite relevant to publicly owned utilities and renewables because publicly owned utilities are able to take advantage of some renewable energy incentives only in a ''buy'' situation, while others accrue only in a ''build'' situation. In particular, possible economic advantages of public utility ownership include: (1) the tax-free status of publicly owned utilities and the availability of low-cost debt, and (2) the renewable energy production incentive (REPI) available only to publicly owned utilities. Possible economic advantages to entering into a PPA with a NUG include: (1) the availability of federal tax credits and accelerated depreciation schedules for certain forms of NUG-owned renewable energy, and (2) the California state production incentives available to NUGs but not utilities. This article looks at a publicly owned utility's decision to buy or build new renewable energy capacity--specifically wind and geothermal power--in California. To examine the economic aspects of this decision, we used a 20-year financial cash-flow model to assess the levelized cost of electricity under four supply options: (1) public utility ownership of new geothermal capacity, (2) public utility ownership of new wind capacity, (3) a PPA for new geothermal capacity, and (4) a PPA for new wind capacity. We focus on wind and geothermal because both resources are abundant and, in some cases, potentially economic in California. Our analysis is not intended to provide precise estimates of the levelized cost of electricity from wind projects and geothermal plants; nor is our intent to compare the levelized costs of wind and geothermal power to one another. Instead, our intent is simply to compare the costs of buying wind or geothermal power to the costs of building and operating wind or geothermal capacity under various scenarios. Of course, the ultimate decision to buy or build cannot and should not rest solely on a comparison of the levelized cost of electricity. Thus, in addition to quantitative analysis, we also include a qualitative discussion of several important features of the ''buy versus build'' decision not reflected in the economic analysis.

Characterization of the geothermal resource at Lackland AFB, San Antonio, Texas. Phase I report  

DOE Green Energy (OSTI)

The geothermal resource under Lackland Air Force Base (AFB), San Antonio, Texas was studied. It is the conclusion of the investigators that a geothermal well drilled at the site recommended by this study has a high probability of delivering geothermal fluids in sufficient quantity and at adequate temperatures to support a projected space and domestic hot water heating system. An exploratory production well location is recommended in the southwest sector of the base, based upon geologic conditions and the availability of sufficient open space to support the drilling operation. It is projected that a production well drilled at the recommended location would produce geothermal fluid of 130 to 145/sup 0/F at a rate of approximately 1000 gpm with reasonable fluid drawdowns. The Environmental Assessment for the drilling portion of the project has been completed, and no irreversible or irretrievable impacts are anticipated as a result of this drilling program. The permitting process is proceeding smoothly.

Heat flow and hot dry rock geothermal resources of the Clearlake Region, northern California  

DOE Green Energy (OSTI)

The Geysers-Clear Lake geothermal anomaly is an area of high heat flow in northern California. The anomaly is caused by abnormally high heat flows generated by asthenospheric uplift and basaltic magmatic underplating at a slabless window created by passage of the Mendocino Triple Junction. The Clear Lake volcanic field is underlain by magmatic igneous bodies in the form of a stack of sill-form intrusions with silicic bodies generally at the top and basic magmas at the bottom. The tabular shape and wide areal extent of the heat sources results in linear temperature gradients and near-horizontal isotherms in a broad region at the center of the geothermal anomaly. The Hot Dry Rock (HDR) portion of The Geysers-Clear Lake geothermal field is that part of the geothermal anomaly that is external to the steamfield, bounded by geothermal gradients of 167 mW/m2 (4 heat flow units-hfu) and 335 mW/m2 (8 hfu). The HDR resources, to a depth of 5 km, were estimated by piece-wise linear summation based on a sketch map of the heat flow. Approximately, the geothermal {open_quotes}accessible resource base{close_quotes} (Qa) is 1.68E+21 J; the {open_quotes}HDR resource base{close_quotes} (Qha) is 1.39E+21 J; and the {open_quotes}HDR power production resource{close_quotes} (Qhp) is 1.01E+21 J. The HDR power production resource (Qhp) is equivalent to 2.78E+ 11 Mwht (megawatt hours thermal), or 1.72E+11 bbls of oil.

Electromagnetic soundings for geothermal resources in Dixie Valley, Nevada  

DOE Green Energy (OSTI)

An electromagnetic (EM) sounding survey was performed over a region encompassing the Dixie Valley geothermal field to map the subsurface resistivity in the geothermal field and the surrounding area. The EM survey, consisting of 19 frequency-domain depth soundings made with the LBL EM-60 system, was undertaken to explore a narrow region adjacent to the Stillwater Range to a depth of 2 to 3 km. Lithologic and well log resistivity information from well 66-21 show that for EM interpretation the section can be reduced to a three-layer model consisting of moderately resistive alluvial sediments, low resistivity lacustrine sediments, and high resistivity Tertiary volcanics and older rocks. This three layer model was used as a starting point in interpreting EM sounding data. Variations in resistivity and thickness provided structural information and clues to the accumulation of geothermal fluids. The interpreted soundings reveal a 1 to 1.5-km-deep low-resistivity zone spatially associated with the geothermal field. The shallow depth suggests that the zone detected is either fluid leakage or hydrothermal alteration, rather than high-temperature reservoir fluids. The position of the low-resistivity zone also conforms to changes in depth to the high resistivity basal layer, suggesting that faulting is a control on the location of productive intervals. 10 refs., 7 figs.

Site-specific analysis of hybrid geothermal/fossil power plants  

DOE Green Energy (OSTI)

A preliminary economic analysis of a hybrid geothermal/coal power plant has been completed for four geothermal Resource areas: Roosevelt Hot Springs, Coso Hot Springs, East Mesa and Long Valley. A hybrid plant would be economically viable at Roosevelt Hot Springs and somewhat less so at Coso Hot Springs. East Mesa and Long Valley show no economic promise. A well-designed hybrid plant could use geothermal energy for boiler feedwater heating, auxiliary power, auxiliary heating, and cooling water. Construction and operation of a hybrid plant at either Roosevelt Hot Springs or Coso Hot Springs is recommended. Brown University provided the theoretical basis for the hybrid study. A modified version of the Lawrence Berkeley Livermore GEOTHM Program is the major analytical tool used in the analysis. The Intermountain Power Project is the reference all coal-fired plant. Costing methods followed recommendations issued by the Energy research and Development Administration.

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.

Preliminary direct heat geothermal resource assessment of the Tennessee Valley region  

DOE Green Energy (OSTI)

A preliminary appraisal of the direct heat geothermal energy resources of the Tennessee Valley region has been completed. This region includes Kentucky, Tennessee and parts of adjacent states. Intermediate and deep aquifers were selected for study. Basement and Top-of-Knox structure and temperature maps were compiled from oil and gas well data on file at various state geological survey offices. Results of this study indicate that the New Madrid seismic zone is the only area within the region that possesses potential for direct heat utilization. In other areas geothermal energy is either too deep for economical extraction or it will not be able to compete with other local energy resources. The only anomalously high temperature well outside the New Madrid seismic zone was located in the Rome Trough and near the central part of the eastern Kentucky coal basin. Geothermal energy in that region would face strong competition from coal, oil and natural gas.

Integrated exploration for low-temperature geothermal resources in the Honey Lake basin, California  

Science Conference Proceedings (OSTI)

An integrated exploration study is presented to locate low-temperature geothermal reservoirs in the Honey Lake area of northern California. Regional studies to locate the geothermal resources included gravity, infrared, water-temperature, and water-quality analyses. Five anomalies were mapped from resistivity surveys. Additional study of three anomalies by temperature-gradient and seismic methods was undertaken to define structure and potential of the geothermal resource. The gravity data show a graben structure in the area. Seismic reflection data, indicate faults associated with surface-resistivity and temperature-gradient data. The data support the interpretation that the shallow reservoirs are replenished along the fault zones by deeply circulating heated meteoric waters.

Feasibility analysis of geothermal district heating for Lakeview, Oregon  

DOE Green Energy (OSTI)

An analysis of the geothermal resource at Lakeview, Oregon, indicates that a substantial resource exists in the area capable of supporting extensive residential, commercial and industrial heat loads. Good resource productivity is expected with water temperatures of 200{degrees}F at depths of 600 to 3000 feet in the immediate vicinity of the town. Preliminary district heating system designs were developed for a Base Case serving 1170 homes, 119 commercial and municipal buildings, and a new alcohol fuel production facility; a second design was prepared for a downtown Mini-district case with 50 commercial users and the alcohol plant. Capital and operating costs were determined for both cases. Initial development of the Lakeview system has involved conducting user surveys, well tests, determinations of institutional requirements, system designs, and project feasibility analyses. A preferred approach for development will be to establish the downtown Mini-district and, as experience and acceptance are obtained, to expand the system to other areas of town. Projected energy costs for the Mini-district are $10.30 per million Btu while those for the larger Base Case design are $8.20 per million Btu. These costs are competitive with costs for existing sources of energy in the Lakeview area.

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

DOE Green Energy (OSTI)

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

Potential for crop drying with geothermal hot water resources in the western United States: alfalfa, a case study. Report 305-100-02  

DOE Green Energy (OSTI)

Preliminary results of engineering, economic, and geographic analysis of the use of low-temperature geothermal heat for the commercial drying of grains, grasses, fruits, vegetables and livestock products in the United States are reported. Alfalfa (lucerne) dehydration was chosen for detailed process and cost study. Six different geothermal heat exchanger/dryer configurations were examined. A conveyor type that could utilize geothermal hot water for its entire heat requirement proved to be the most economical. A capital cost estimate for an all-geothermal alfalfa dehydration plant near the Heber Known Geothermal Resource Area in the Imperial Valley, California was prepared. The combined cost for heat exchangers and dryer is about $1.6 million. Output is about 11 metric tons per hour. Acreage, production and dollar value data for 22 dryable crops were compiled for the areas surrounding identified hydrothermal resources in 11 western states. The potential magnitude of fossil fuel use that could be replaced by geothermal heat for drying these crops will be estimated.

Seismic methods for resource exploration in enhanced geothermal systems  

DOE Green Energy (OSTI)

A finite-difference modeling study of seismic wave propagation was conducted to determine how to best investigate subsurface faults and fracture zones in geothermal areas. The numerical model was created based on results from a previous seismic reflection experiment. A suite of fault models was investigated including blind faults and faults with surface expressions. The seismic data suggest that blind faults can be detected by a sudden attenuation of seismic wave amplitudes, as long the fault is located below the receiver array. Additionally, a conversion from P- to S-waves indicates the reflection and refraction of the P-waves while propagating across the fault. The drop in amplitudes and the excitation of S-waves can be used to estimate the location of the fault at depth. The accuracy of the numerical modeling depends on the availability of a priori in situ information (velocity and density) from borehole experiments in the geothermal area.

Exploration ofr geothermal resources in Dixie Valley, Nevada  

Science Conference Proceedings (OSTI)

A case history of SUNEDCO's exploratory efforts, which ultimately led to the drilling and discovery of the Dixie Valley goethermal field, is presented. The geochemistry from three active lot springs in the area: Dixie Hot Springs, South Hot Springs, and Hyder Hot Springs, was examined. Two heat flow drilling programs were conducted at Dixie Hot Springs consisting of 45 temperature gradient holes ranging in depth from 30 to 1500 ft. From this program a heat-flow anomaly was mapped extending along the Stillwater Range front in which temperature gradients are greater than 100/sup 0/c/Km. in 1978, the number 1 SW Lamb well was drilled on a 152 acre farmout from Chevron. The well was completed as a geothermal producer in a zone of fractured volcanic rocks. Since then, five additional geothermal producing wells were completed within the anomalous area. (MJF)

Geothermal and heavy-oil resources in Texas  

Science Conference Proceedings (OSTI)

In a five-county area of South Texas, geopressured-geothermal reservoirs in the Paleocene-Eocene Wilcox Group lie below medium- to heavy-oil reservoirs in the Eocene Jackson Group. This fortuitous association suggests the use of geothermal fluids for thermally enhanced oil recovery (TEOR). Geothermal fairways are formed where thick deltaic sandstones are compartmentalized by growth faults. Wilcox geothermal reservoirs in South Texas are present at depths of 11,000 to 15,000 ft (3,350 to 4,570 m) in laterally continuous sandstones 100 to 200 ft (30 to 60 m) thick. Permeability is generally low (typically 1 md), porosity ranges from 12 to 24 percent, and temperature exceeds 250{degrees}F (121{degrees}C). Reservoirs containing medium (20{degrees} to 25{degrees} API gravity) to heavy (10{degrees} to 20{degrees} API gravity) oil are concentrated along the Texas Coastal Plain in the Jackson-Yegua Barrier/Strandplain (Mirando Trend), Cap Rock, and Piercement Salt Dome plays and in the East Texas Basin in Woodbine Fluvial/Deltaic Strandplain and Paluxy Fault Line plays. Injection of hot, moderately fresh to saline brines will improve oil recovery by lowering viscosity and decreasing residual oil saturation. Smectite clay matrix could swell and clog pore throats if injected waters have low salinity. The high temperature of injected fluids will collapse some of the interlayer clays, thus increasing porosity and permeability. Reservoir heterogeneity resulting from facies variation and diagenesis must be considered when siting production and injection wells within the heavy-oil reservoir. The ability of abandoned gas wells to produce sufficient volumes of hot water over the long term will also affect the economics of TEOR.

Present status and future prospects for nonelectrical uses of geothermal resources  

DOE Green Energy (OSTI)

This report, which is part of a study initiated by the NATO Committee on the Challenges of Modern Society (CCMS), describes the current status of nonelectrical uses of geothermal resources. Such resources are defined as geothermal fluids between the temperatures of 50 and 160/sup 0/C. Current and potential uses of these resources including residential and commercial, agricultural and industrial applications are described. Also discussed are exploration and drilling; extraction and distribution; environmental impact; and economic and regulatory problems. Applications in a number of countries are described. Among the report's conclusions are: (1) Geothermal resources are widely distributed throughout the world. (2) The extraction of these resources presents no serious technical problems. (3) A wide variety of economically viable applications for these resources currently exists. (4) Current nonelectrical applications have a favorable economic structure compared with those of other energy sources. (5) Disposal of spent fluids has a significant ecological impact. Reinjection appears to be the most likely alternative. (6) The legal and institutional framework surrounding these applications needs both clarification and simplification.

Investigation of Low-Temperature Geothermal Resources in the Sonoma Valley Area, California  

DOE Green Energy (OSTI)

The Sonoma Valley area contains low-temperature geothermal resources (20 C {le} T {le} 90 C) having the potential for useful development. Sonoma Valley residents, local governments and institutions, private developers, and manufacturers may be able to utilize the geothermal resources as an alternate energy source. Historically, there have been at least six geothermal spring areas developed in the Sonoma Valley. Four of these (Boyes Hot Springs, Fetter's Hot Springs, Agua Caliente Springs, and the Sonoma State Hospital warm spring) lie on a linear trend extending northwestward from the City of Sonoma. Detailed geophysical surveys delineated a major fault trace along the east side of the Sonoma Valley in association with the historic geothermal areas. Other fault traces were also delineated revealing a general northwest-trending structural faulting fabric underlying the valley. Water wells located near the ''east side'' fault have relatively high boron concentrations. Geochemical evidence may suggest the ''east side'' fault presents a barrier to lateral fluid migration but is a conduit for ascending fluids. Fifteen of the twenty-nine geothermal wells or springs located from literature research or field surveys are located along or east of this major fault in a 10 km (6.2 miles) long, narrow zone. The highest recorded water temperature in the valley appears to be 62.7 C (145 F) at 137.2 meters (450 feet) in a well at Boyes Hot Springs. This is consistent with the geothermal reservoir temperature range of 52-77 C (126-171 F) indicated by geothermometry calculations performed on data from wells in the area. Interpretation of data indicates a low-temperature geothermal fluid upwelling or ''plume'', along the ''east side'' fault with subsequent migration into permeable aquifers predominantly within volcanic strata. It is quite likely other geothermal fluid ''plumes'' in association with faulting are present within the Sonoma Valley area. A 5.8 km{sup 2} geothermal zone, that parallels the fault trace, is delineated and is perhaps the most favorable area for further investigation and possible geothermal production.

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.
