Beowawe Geothermal-Resource Assessment. Final Report. Shallow-Hole Temperature Survey Geophysics and Deep Test Hole Collins 76-17

摘要

Geothermal resource investigation field efforts in the Beowawe Geysers Area, Eureka County, Nevada are described. The objectives included acquisition of geotechnical data for understanding the nature and extent of the geothermal resource boundaries south of the known resource area. Fourteen shallow (<500 feet) temperature-gradient holes plus geophysics were used to select the site for a deep exploratory well, the Collins 76-17, which was completed to a total depth of 9005 feet. Maximum downhole recorded temperature was 311 exp 0 F, but no flow could be induced. (ERA citation 08:045919)
