摘要： Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for using a thin-bed hot sedimentary aquifer (HSA) in geothermal energy generation applications. An example embodiment operates by pumping, via an extraction well, heated water from an extraction depth of an HSA. The HSA is identified based on a permeability satisfying a threshold permeability range and could even have a thickness equal to or less than about 100 meters. The example embodiment further operates by extracting, via a power generation unit, heat from the heated water to generate power and transform the heated water into cooled water. Subsequently, the example embodiment operates by injecting, via an injection well, the cooled water at an injection depth of the HSA. A first portion of the extraction well and a second portion of the injection well are disposed within the HSA.

摘要： Systems and methods are described for generating electricity from fluid produced from a subsurface formation. The disclosed systems and methods include generating electrical power using the energy content of fluids produced from the earth or hot fluids created during surface processing of the produced fluids. Fluid is obtained from a well in the subsurface formation and provided to a first power generation device where a pressure and a temperature of the fluid is adjusted to a pressure and a temperature compatible with the first power generation device using one or more valves coupled to the first power generation device. The first power generation device generates electricity from the fluid. One or more second power generation devices also generate electricity using the fluid where one of the second power generation devices is a thermoelectric generator.

摘要： A method for extracting a fuel from a geologic formation comprises heating a target volume in the geologic formation to generate the fuel via thermal conversion of a precursor material, thereby also heating a part of the geologic formation, extracting the generated fuel from the geologic formation; recovering heat from the geologic formation; and using the recovered heat for one or more of: heating the target volume, heating a different target volume, extracting the fuel, recovering the heat from the geologic formation, processing the extracted fuel, and converting the recovered heat into another form of storable energy.

摘要： A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

摘要： A system comprises a production well having an inlet in fluid communication with an underground reservoir, wherein the reservoir is at a first temperature and contains a native aqueous solution, a working fluid withdrawn from the reservoir into the inlet and through the production well. The working fluid comprises a non-water component and an aqueous component comprising a portion of the aqueous solution. The system further comprises a separation apparatus in communication with the production well configured to separate the aqueous component from the working fluid to provide a dewatered working fluid, wherein the aqueous component is from more than 0 wt. % to no more than a specified threshold of the dewatered working fluid. The system also includes an energy recovery system that comprises an expansion device through which the dewatered working fluid passes and produces work energy and a generator that converts the work energy to electricity.

摘要： A system comprises an injection well for accessing reservoir at a first temperature; a production well in fluid communication with the reservoir; a working-fluid supply system providing a non-water based working fluid to the injection well at a second temperature lower than the first temperature, wherein exposure of the working fluid to the first temperature heats the working fluid to a third temperature and at least a portion of the working fluid at the third temperature is produced as a production fluid; and an energy recovery system that converts energy contained in the production fluid to electricity or heat, wherein the energy recovery system includes a waste heat recovery apparatus that recovers waste heat and uses it to heat the production fluid to a fourth temperature that is higher than the third temperature, wherein the waste heat is recovered from equipment of or a process stream.
