EXPLORATION 7.10 Coupled Reservoir Simulation and Geophysical Surveys DOE supported research to assess the feasibility of finding “hidden” or “blind” geothermal reservoirs using a combination of existing electrical exploration methods and reservoir simulations to predict fluid flow within a geothermal system and the resulting geophysical signal generated by that flow. 305-306 Beowawe and Dixie Valley were used as test cases. The study 1) theoretically investigated the feasibility of finding “hidden” geothermal reservoirs in the Basin and Range using electrical surveys, 2) identified operating geothermal fields in the Basin and Range for which both electrical exploration surveys and adequate reservoir information are available, and 3) examined the correlation between the subsurface geothermal reservoir and the surface electrical surveys using detailed numerical modeling. The studies established the potential utility of coupling reservoir simulation and electrical surveys. DOE also supported the development of a statistical approach to integrate the different model constraints provided by disparate geophysical, geological, and geochemical data in a rigorous and consistent manner by formal joint inversion. Researchers identified how this approach could be applied at Dixie Valley and the Salton Sea Geothermal Field. 307 86 A History of Geothermal Energy Research and Development in the United States | Exploration
EXPLORATION STRATEGIES / 8 8.0 Exploration Strategies From its earliest days, DOE recognized the importance of having and following a strategy to minimize cost and maximize success in exploring for and evaluating geothermal resources. It was important to determine which of the techniques used for geothermal exploration did not identify a geothermal system. DOE funded several geothermal companies to discuss both failed and successful techniques. Geothermal exploration strategies were developed along lines similar to those used in exploring for metallic minerals, which proved very helpful to the nascent geothermal industry. The results were presented in a series of seminal papers on geothermal exploration. These papers included case studies of individual geothermal systems, exploration strategies, the application and limitations of individual techniques, and conceptual models of geothermal systems. 13/199/227/308-312 A History of Geothermal Energy Research and Development in the United States | Exploration 87
