Deep Geothermal Heat Storage under Oilsands - Can We Use it to Help Oilsands Industry? New EGS Concept Proposed
The research into a geothermal energy option for a deeper crystalline basement heat source in the Northern Alberta basin as a potential artificially fractured subsurface heat exchanger to deliver heat for oilsands processing and/or deep geothermal energy for heating to offset CO2 emission is current...
