Geothermal Reservoir Assessment Case Study: Northern Basin and Range Province, Leach Hot Springs Area, Pershing County, Nevada. Final report, April 1979-December 1981
A Geothermal Reservoir Assessment Case Study was conducted in the Leach Hot Springs Known Geothermal Resource Area of Pershing County, Nevada. The case study included the drilling of twenty-three temperature gradient wells, a magnetotelluric survey, seismic data acquisition and processing, and the drilling of one exploratory well. Existing data from prior investigations, which included water geochemistry, gravity, photogeologic reports and a hydrothermal alteration study, was also provided. The exploratory well was drilled to total depth of 8565' with no significant mud losses or other drilling problems. A maximum temperature of 260/sup 0/F was recorded at total depth. The relatively low temperature and the lack of permeability (as shown by absence of mud loss) indicated that a current, economic geothermal resource had not been located, and the well was subsequently plugged and abandoned. However, the type and extent of rock alteration found implied that an extensive hot water system had existed in this area at an earlier time. This report is a synopsis of the case study activities and the data obtained from these activities.
