The Coso EGS project - Recent developments

January 1, 2005

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