ABSTRACT:
Crushed raw oil shale is fed into a geothermal compartment or reservoir under oil shale retorting conditions using the reservoir as a source of heat for retorting. After retorting is completed hydrocarbon products are removed from the compartment or reservoir. The resultant spent shale is subsequently used to fill voids in the reservoir. Hydraulic fluids are then placed into the compartment or reservoir and sufficient pressure applied to fracture the reservoir or compartment causing another geothermal compartment or reservoir to be formed.
