Preliminary hydrogeologic appraisal of selected hydrothermal systems in northern and central Nevada

Abstract

Reservoir parameters include the three-dimensional distribution of flow boundaries, effective porosity, intrinsic permeability, specific storage, specific heat, thermal conductivity, and rock chemical and mineralogical composition. Some of these parameters may be inferred from surface geologic ] and geophysical evidence, but useful quantitative data generally must be obtained by costly deep drilling into the geothermal reservoir.
