Abstract: A turbine for use in a power system includes a first impeller having a first impeller configuration. The turbine is operated at a location of the power system to drive a generator to generate electricity. The turbine is configured such that the first impeller may be removed from the turbine and replaced by a second impeller while the turbine remains in situ at the location where the turbine had been operated. The second impeller has a second impeller configuration different from the first impeller configuration. The changing of the first impeller to the second impeller may be in response to thermal decline of a geothermal resource, ambient temperature variations, or a change in the fluid used to operate the turbine.

Abstract: A geothermal power system includes a pressure exchanger fluidically coupled to a heat exchanger. A first fluid enters the pressure exchanger at a first inlet, and flows in a first fluid path to a first outlet. The first fluid flows from the first outlet to the heat exchanger, where the first fluid heats a second fluid. The first fluid flows from the heat exchanger to a second inlet of the pressure exchanger. The first fluid flows in a second fluid path through the pressure exchanger to a second outlet. A pressure of the first fluid reduces as the first fluid transits through the pressure exchanger along the first fluid path. A pressure of the first fluid increases as the first fluid transits through the pressure exchanger along the second fluid path. The first fluid flows from the second outlet to a turbine which drives a generator.

Abstract: A first fluid is produced from a first subterranean formation, and the fluid is used to generate electricity and/or heat a second fluid. The first fluid is injected into a second subterranean formation that is different from the first subterranean formation. The first fluid is transferred from the second subterranean formation to the first subterranean formation. In some implementations, the first fluid is produced from the first subterranean formation at a first zone of a well, and is injected into the second subterranean formation at a second zone of the well. In some implementations, the generation of electricity using the first fluid is performed with an electrical submersible generator installed in the well. In some implementations, the transfer of the first fluid from the second subterranean formation to the first subterranean formation is performed using the electrical submersible generator as a pump.

Abstract: A well is completed in a subterranean formation with first and second fractures. Geothermal fluid flows into the well via the first fracture while flow into the well via the second fracture is prevented. Geothermal fluid flows into the well via the second fracture while flow into the well via the first fracture Is prevented. Fluidic access in the well to the first and second fractures is closed off. Then the well is recompleted on the subterranean formation by creating third and fourth fractures in the subterranean formation. The first, second, third, and fourth fractures are discrete from each other. Geothermal fluid flows into the well via the third fracture while flow into the well via the first, second, and fourth fractures is prevented. Geothermal fluid flows into the well via the fourth fracture while flow Into the well via the first, second, and third fractures is prevented.
