Thermal Conductivity of Rocks Associated with Energy Extraction from Hot Dry Rock Geothermal Systems [PDF]

, 1978
Because the lifetime of and heat extraction rate from a hot dry rock (HDR) geothermal reservoir can be substantially controlled by the in situ rock thermal conductivity, information concerning the dependence of thermal conductivity on moisture content and temperature is important for proper design and management of the reservoir.

Comparative Analysis of Power Plant Options for Enhanced Geothermal Systems (EGS)

Energies, 2014
Enhanced geothermal systems (EGS) extract heat from underground hot dry rock (HDR) by first fracturing the HDR and then circulating a geofluid (typically water) into it and bringing the heated geofluid to a power plant to generate electricity. This study
