摘要

Estimates suggest that the Great Basin region is capable of producing much greater amounts of geothermal energy than the current ~600 MW from ~24 power plants. Because most of the geothermal resources in this region are blind, it is imperative that the favorable characteristics for geothermal activity be synthesized and methodologies developed to discover new robust systems. Nine geologic, geochemical, and geophysical parameters were synthesized to produce a new detailed geothermal play fairway map of a large transect across the Great Basin region (96,000 km~2) from west-central to eastern Nevada. These parameters were grouped into subsets to delineate rankings for local permeability, regional permeability, and heat, which collectively defined geothermal play fairways (i.e., most likely locations for significant geothermal fluid flow). The primary objective of this work was to reduce the risks in geothermal exploration and thus facilitate discovery of commercial-grade, blind geothermal fields. Two dozen highly prospective areas, including both known systems and previously undiscovered potential blind systems, have been identified across the region for further analysis, of which several will be selected for detailed studies. Multiple techniques, including detailed geologic mapping, shallow temperature surveys, detailed gravity surveys, LiDAR, geochemical studies, seismic reflection analysis, and 3D modeling, are being employed in the detailed studies. Initial work on the detailed studies has begun and will proceed over the next year.
