Project Title Application of a New Structural Model and Exploration Technologies to Define a Blind Geothermal System: A Viable Alternative to Grid-Drilling for Geothermal Exploration: McCoy, Churchill County, NV
Project Type / Topic 1 Recovery Act: Geothermal Technologies Program
Project Type / Topic 2 Validation of Innovative Exploration Technologies

Project Description The structural model is based on the role of subsurface igneous dikes providing a buttressing effect in a regional strain field such that permeability is greatly enhanced. The basic thermal anomaly at McCoy was defined by substantial U.S. Department of Energy-funded temperature gradient drilling and geophysical studies conducted during the period 1978 to 1982. This database will be augmented with modern magnetotelluric, controlled-source audio-magnetotelluric, and 2D/3D reflection seismic surveys to define likely fluid up-flow plumes that will be drilled with slant-hole technology. Two sites for production-capable wells will be drilled in geothermally prospective areas identified in this manner. The uniqueness of this proposal lies in the use of a full suite of modern geophysical tools, use of slant-hole drilling, and the extensive technical database from previous DOE funding.
State Nevada
Objectives To verify a new structural geologic concept related to hosting of a blind geothermal resource at the McCoy geothermal area in the prolific north-central Nevada geothermal province. Such a model has transferability to other geographic locations in the Basin & Range province.
