Reservoir Stimulation Optimization with Operational Monitoring for Creation of EGS

Sep 25, 2013
65.42 MB
Publicly accessible
EGS field projects have not sustained production at rates greater than half 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, igne...
