Tech Report Dual Packer Opens Geothermal Source at 11,000 psi
Successful stress test proves geothermal feasibility by fracturing a formation at 11,000 psi (~6,400 differential pressure).
Fail-safe closure in an emergency
A surface-operated hydraulic safety valve is necessary for applying fail-safe closure of the test string during testing operations.
Whether the emergency requiring a quick shutdown response is overpressure, equipment failure, or a downstream leak, having a surface safety valve (SSV) installed in the BOP stack of a jackup or land rig increases operational safety while reducing environmental risk.
