Reservoir Stimulation Optimization with Operational Monitoring for Creation of EGS

Sep 15, 2014
21.38 MB
Publicly accessible
EGS field projects have not sustained production at rates greater than 1/2 of what is needed for economic viability. The primary limitation that makes commercial EGS infeasible is our current inability to cost-effectively create high-permeability reservoirs from impermeable, igneo...
