摘要： The present disclosure relates to systems and methods of enhanced geothermal energy production that transports fluid from existing underground fluid reservoirs to a deeper, higher temperature radiator zone for fluid heating before recovery at the surface. One system includes at least one radiator injection well extending from a subterranean water reservoir of a formation to a radiator zone of the formation that is located at a greater depth than the subterranean water reservoir. The radiator injection well is configured to fluidically couple the subterranean water reservoir with the radiator zone to transfer fluid contained in the subterranean water reservoir to the radiator zone for heating. At least one recovery well extends from the surface to the radiator zone and is configured to recover fluid from the radiator zone that was transferred from the subterranean water reservoir to the radiator zone. The recovered fluid is then used at the surface to generate electricity.

摘要： A method for producing hydrogen by thermochemical splitting of water includes injecting one or more feed streams of water into a reaction chamber. The method further includes using heat from a subterranean heat source to carry out the thermochemical splitting of water to form hydrogen and oxygen in the reaction chamber. The formed products are subsequently removed from the reaction chamber.

摘要： A pitless adapter includes a casing having first, second and third ports, and a spool having a top plate, a bottom plate having first, second and third ports, a first middle plate between the top and bottom plates and a second middle plate between the first middle plate and the bottom plate. The casing, the top plate and the first middle plate define a first chamber that is open to the first port of the casing and the first port of the spool. The casing, the first middle plate and the second middle plate define a second chamber that is open to the second port of the casing and the second port of the spool. The casing, the second middle plate and the bottom plate define a third chamber that is open to the third port of the casing and the third port of the spool.

摘要： The present disclosure is directed to systems, methods and tools that measure ionic concentrations and downhole enthalpy of a flowing geothermal fluid in real-time at high-temperature and pressure. The systems, methods and tools include measuring the concentration of selected naturally occurring ions found in the liquid phase of the geothermal fluid throughout the wellbore using novel electrochemical sensor technologies. The change in liquid-phase ion concentration will be used to calculate the proportion of liquid to steam and allow for accurate enthalpy measurements. The techniques and technologies described here can be applied to any application of electrochemical sensing in extreme environments.

摘要： A geothermal heat mining system can operate within a single primary borehole in a geothermal reservoir. A primary fluid loop can include a cold working fluid line leading into the primary borehole and a hot working fluid line coming out of the primary borehole. A secondary fluid loop can be located down the primary borehole, where the secondary fluid loop is in thermal contact with the geothermal reservoir. A downhole heat mining device can control a rate of heat transfer from the secondary fluid loop to the primary fluid loop by selectively controlling fluid flow through the primary fluid loop, the secondary fluid loop, or both.

摘要： A geothermal energy system utilizes supercritical CO2 turbine and a radial outflow reaction turbine, a Catherine Wheel having wheel arms, that spins around an axle to produce power. A fin portion extends from the radial portion at an offset angle, to an exhaust end. A first working fluid, such as supercritical carbon dioxide flows through an arm conduit within the wheel arm and a second working fluid, such as a hydrocarbon mixes with the first working fluid and both flow through a turbine. The turbine may be configured within the wheel arm conduit or mounted prior to the Catherine Wheel or any other radial outflow reaction turbine, or variable phase turbines available, and it turns as the combined working fluids expand and vaporize. The second working fluid may be condensed and recirculated while the first working fluid is expelled back into a geothermal reservoir.

摘要： A geothermal power plant and method of operating a geothermal power plant in which control over the creation and growth of fractures in the geothermal formation is achieved. A downhole pressure gauge (14) with a high data acquisition rate is located in the injection or production well. Pressure changes in the well are recorded as a pressure trace and transmitted to the surface as data. The data is analysed to determine fracture parameters of the geothermal formation. The pump rate of the well is then varied in response to the calculated fracture parameter(s).

摘要： A system for extracting geothermal heat energy includes a geothermal well in surrounding crust material, extending from a well top part down to a well bottom part at a depth where the surrounding crust material has elevated geothermal temperatures. The geothermal well further includes a heat medium contained within geothermal well walls. The heat medium is heated at the well bottom part by heat extracted from the surrounding crust material, evaporating and rising, carrying heat energy towards the well top part A heat extractor extracts the heat energy available at the well top part carried by the heat medium. At least one heat conductive path is provided in the surrounding crust material, the heat conductive path extending outwardly from the geothermal well into the crust material to conduct geothermal heat from the crust material surrounding the path towards the well bottom part.

摘要： A method and apparatus for recycling unused or suspended wells and areas with predetermined suitability for well installation. In one embodiment, existing unused well sites are repurposed for contact in or adjacent a geothermal zone. Drilling extends horizontally in direct contact with the geothermal zone for heat transfer and subsequently terminates at a newly drilled well. The heated working liquid within the sealed annulus is cooled within a sealed top loop at or below the surface and recirculated for further heat transfer. The closed loop is continuous above and below the geothermal formation and can cluster several such arrangements and also consolidate clusters in a drilling field of unused wells. The loop may be incorporated in areas with predetermined suitability (greenfield) for well installation.
