WELL SYSTEM FOR RECOVERY OF GEOTHERMAL ENERGY

Resumen de: WO2026190276A1

A well system for recovery of geothermal energy, the system having an injector well having a lateral section extending through a formation between horizontally spaced heel and toe portions of the injector well, and a producer well having a lateral section extending through the formation between horizontally spaced heel and toe portions of the producer well. The lateral sections extend substantially parallel to each other. The formation contains a fracture zone centred on a longitudinal fracture plane which contains the lateral sections. The fracture zone places the lateral sections in fluid communication. The well system is configured to flow a heat recovery fluid into the lateral section of the injector well at the heel portion thereof, pass the flow through the fracture zone, and collect the flow from the lateral section of the producer well at the heel portion thereof.

Resumen de: US20260275967A1

A system includes a pressure exchanger (PX) configured to exchange pressure between a first fluid and a second fluid. The system further includes a flow valve configured to receive the second fluid output from the PX and a third fluid. The flow valve is further configured to combine the third fluid with the second fluid. The system further includes a heat exchanger configured to exchange corresponding thermal energy between the first fluid output from the PX and the second fluid output from the PX. The system further includes a turbine configured to convert corresponding energy of the second fluid output from the heat exchanger into rotational kinetic energy.

WELL SYSTEM FOR RECOVERY OF GEOTHERMAL ENERGY

Resumen de: WO2026190274A1

Enhanced Geothermal System A well system for recovery of geothermal energy, the system having an injector well having a lateral section extending through a formation between horizontally spaced heel and toe portions of the injector well, and a producer well having a lateral section extending through the formation between horizontally spaced heel and toe portions of the producer well. The lateral sections extend substantially parallel to each other in a heel-to-toe arrangement with the heel portion of the injector well adjacent the toe portion of the producer well and the toe portion of the injector well adjacent the heel portion of the producer well. The formation contains a plurality of fractures on planes which are substantially perpendicular to and distributed along the lateral sections, the perpendicular fractures placing the lateral sections in fluid communication. The well system is configured to receive a heat recovery fluid into the lateral section of the injector well at the heel portion thereof, pass the heat recovery fluid through the fractures, and collect the heat recovery fluid from the lateral section of the producer well at the heel portion thereof. The lateral section of the injector well contains an injector well plug and the lateral section of the producer well contains a producer well plug, each plug forms a local block to fluid flow through the respective lateral section, and the plugs are at staggered positions such that a flow of the heat recovery fluid

The thermoelectric power generation module comprises at least two heat exchangers arranged adjacent to each other at an interval, the adjacent two heat exchangers are respectively a hot heat exchanger and a cold heat exchanger, a plurality of thermoelectric modules for thermoelectric power generation are arranged between the two heat exchangers, the hot water supply system is connected with the hot heat exchanger, and the cold water supply system is connected with the cold heat exchanger. A hot end and a cold end are formed by oppositely arranging the hot heat exchanger and the cold heat exchanger, and the thermoelectric module is arranged between the hot end and the cold end, so that a whole structure is modularized.

Fracturing Hot Rock

Resumen de: US20260276245A1

A system and method for harnessing geothermal energy using fracturing of hot rock. The system has at least a first well and a second well. The method involves introducing an alkali metal downhole in a first well. A solution is also introduced into the first well. The solution produces an exothermic reaction with the alkali metal. The gas and heat fracture the hot rock producing fractures. The fractures fluidly connects the first well to the second well. A solution, such as water, can be pumped through the first well, through the fractures, and into the second well. The hot rock passes geothermal energy to the water which can then be utilized.
