Electric potential changes prior to shear fracture in dry and saturated rocks [PDF]
, 1998 Electric potential changes before shear rupture were measured using Darley Dale sandstone (quartz-rich) and Icelandic basalt (quartz-free) on both dry specimens and in the presence of pore fluid.

Geothermal energy sources and possibilities of their exploitation [PDF]
Acta Montanistica Slovaca, 2007 The geothermal energy is everywhere beneath the surface of the earth. The earth’s interior is enormous thermal reservoir of energy, which can be utilized if favorable geological conditions exist.The electricity generation in 1942 at Larderello was a ...

DOE hot dry rock program [PDF]
, 1980 Hydraulic fracturing has been used to create and subsequently to enlarge the first hot dry rock heat-extraction loop at Fenton Hill, New Mexico. Encouraging results prompted the DOE to expand this project into a program of national scope. The elements of

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
