Systems for generating geothermal power in an organic Rankine cycle operation during hydrocarbon production based on wellhead fluid temperature
Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation in the vicinity of a wellhead during hydrocarbon production 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 wellhead fluid from the wellhead 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 wellhead 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.

METHOD, SYSTEM AND APPARATUS FOR EXTRACTING HEAT ENERGY FROM GEOTHERMAL BRINY FLUID
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.
Power generation process
A process for the generation of power is disclosed. The process comprises receiving a wastewater stream containing organic matter and passing the wastewater stream to an anaerobic digester in which the organic matter contained therein is broken down to produce biogas. The liquid content of said wastewater stream is reduced before said stream enters the anaerobic digester by passing the wastewater stream through an osmotic power unit. The said stream is passed over one side of a semi-permeable membrane which permits the passage of water but not the passage of salts, an aqueous stream of higher salinity than said wastewater stream being passed over the other side of said membrane such that latent osmotic energy present in said aqueous stream of higher salinity is converted into electricity.
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 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.
