In-situ Stress and Fracture Characterization for Planning of an Egs Stimulation in the Desert Peak Geothermal Field , Nevada

  title={In-situ Stress and Fracture Characterization for Planning of an Egs Stimulation in the Desert Peak Geothermal Field , Nevada},
  author={Stephen H. Hickman and Nicholas C. Davatzes and U. S. Geological},
An integrated study of natural fracture geometry, fluid flow and stress was conducted in Desert Peak well 27-15 in preparation for development of an Enhanced Geothermal System (EGS) through hydraulic stimulation. This stimulation will be carried out at depths of ~3000 to 3500 ft in units comprised of silicified rhyolite tuffs and metamorphosed mudstones at ambient temperatures of ~180 to 195° C. Our previous analyses of borehole image logs from this well showed that the current minimum… CONTINUE READING
