ABSTRACT:
A method for producing geothermal energy and minerals from subterranean high temperature and high salinity water reservoirs by injecting low salinity water at ambient surface temperature into the reservoir through a well bore, allowing the injected water to become heated in the reservoir and then producing water through the well bore to the surface for use as a source of energy and, optionally, minerals. Simultaneously with the employment of certain wells for injection-production cycles, other wells may be employed predominantly for injection of water to displace heat and in-situ well brines to well bores which produce such water and brines to the surface for utilization of their heat energy and dissolved minerals.
