Abstract: Provided is a geothermal heat system having reduced heat source residual heat of a geothermal heat pump. The geothermal heat system includes a ground heat exchanger unit, a geothermal heat pump, and a residual heat storage tank. A portion of heat source residual heat remaining in the geothermal heat pump is transferred on a geothermal heat exchange medium passing through the geothermal heat pump so as to be stored in the residual heat storage tank. As the internal temperature of the residual heat storage tank gradually becomes the same as the temperature of the underground, the thermal load of the underground is removed. At least a portion of the heat source residual heat produced during provision of cooling/heating to the location of use is processed, thereby improving the operating efficiency of the geothermal heat system having reduced heat source residual heat of a geothermal heat pump.

Abstract: Systems and methods for producing energy from a geothermal formation. A heat exchanger can be disposed within a well to absorb heat from a geothermal formation. The heat exchanger can be supported within the well using a high thermal conductivity material. The heat exchanger is connected to an organic Rankine cycle engine including a secondary heat exchanger and a turbine. The primary and secondary heat transfer fluids are chosen to maximize efficiency of the organic Rankine cycle.

Abstract: Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation to thereby supply electrical power to one or more of in-field operational equipment, a grid power structure, and an energy storage device. In an embodiment, during hydrocarbon production, a temperature of a flow of heated fluid from a source or working fluid may be determined. If the temperature is above a vaporous phase change threshold of the working fluid, heat exchanger valves may be opened to divert flow of heated fluid to heat exchangers to facilitate heat transfer from the flow of wellhead fluid to working fluid through the heat exchangers, thereby to cause the working fluid to change from a liquid to vapor, the vapor to cause a generator to generate electrical power via rotation of an expander.

Abstract: In a method, an electrical grid is monitored. Based on monitoring the electrical grid, it is determined that one or more criteria are satisfied at a first time. In response to determining that the one or more criteria are satisfied at the first time, water is moved from an aquifer located at a first elevation to a reservoir located at a second elevation. The first elevation is lower than the second elevation. The water is moved from the reservoir through a heat exchanger, and heat is transferred using the water. Subsequent to moving the water through the heat exchanger, the water is moved into the aquifer.

Abstract: The present disclosure relates to techniques for extracting heat energy from geothermal briny fluid. A briny fluid can be extracted from a geothermal production well and delivered to a heat exchanger. The heat exchanger can receive the briny fluid and transfer heat energy from the briny fluid to a molten salt. The molten salt can be pumped to a molten salt storage tank that can serve as energy storage. The briny fluid can be returned to a geothermal source via the production well. The briny fluid can remain in a closed-loop system, apart from the molten salt, from extraction through return to the geothermal production well.

Abstract: A new system for and a method of deploying a heat exchanger pipe. A bore hole is drilled from an access ditch location to a terminal ditch location using a piloted drill head powered via an umbilical attached to the piloted drill head. A casing is attached to the piloted drill head and disposed about the umbilical into the bore hole from the access ditch location to the terminal ditch location. At the terminal ditch location, the piloted drill head is removed from the casing and the umbilical and a heat exchanger pipe is attached to the umbilical. The umbilical is withdrawn from within the casing deployed in the bore hole to pull the heat exchanger pipe into the casing. The casing is then withdrawn from the bore hole leaving the heat exchanger pipe in the bore hole.

Abstract: 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 and is entirely subsurface. 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.
