Geothermal heat recovery from high-temperature, low-permeability geologic formations for power generation using closed loop systems

A method or apparatus that uses a fluid in a closed loop well system to extract heat from geothermal resources that are located in or near high-temperature, low-permeable geologic formations to produce power. In some embodiments, the closed loop system may include one or more heat exchange zones, wh...

Beschreibung
Zusammenfassung:	A method or apparatus that uses a fluid in a closed loop well system to extract heat from geothermal resources that are located in or near high-temperature, low-permeable geologic formations to produce power. In some embodiments, the closed loop system may include one or more heat exchange zones, where at least a portion of the one or more heat exchange zones may be disposed within a subterranean region having a temperature of at least 350° C. The subterranean region may be within a plastic zone or within 1000 meters of the plastic zone, the plastic zone having a temperature gradient of at least 80° C. per kilometer depth.
