CLOSED LOOP ENERGY PRODUCTION FROM PRODUCING GEOTHERMAL WELLS

Methods and systems for producing thermal or electrical power from geothermal wells. Power is produced from a working fluid circulating in a closed loop within a geothermal well. Geothermal steam or brine at depth transfers heat at higher temperature than at the surface to the working fluid. The wor...

Beschreibung
Zusammenfassung:	Methods and systems for producing thermal or electrical power from geothermal wells. Power is produced from a working fluid circulating in a closed loop within a geothermal well. Geothermal steam or brine at depth transfers heat at higher temperature than at the surface to the working fluid. The working fluid is then used to produce power directly or indirectly. The geothermal production fluid may be stimulated through use of gas lifting or submersible pumps to assist in bringing such fluids to the surface or through the use blockers to encourage the downhole steam advection and brine recirculation through the resource in a connective loop, The working fluid may be compatible with existing direct heat or power generation equipment; i.e., water for flash plants or hydrocarbons/refrigerants for binary plants.
