An Enhanced Geothermal System at Coso, California—Recent Accomplishments

摘要: An Enhanced Geothermal System (EGS) field experiment will be conducted to hydraulically stimulate injection well 34-9RD2, located on the east flank of Coso geothermal reservoir, with objective increasing rate this 750 gpm at a wellhead pressure 100 psi or less. The stimulation is expected create hydraulic communication recently drilled production 38C-9, which directly south 34-9RD2. We summarize results fracture and stress analyses based upon borehole image logs 38C-9; petrographic petrologic cuttings from both 34-9RD2 plans for redrilling
