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.

A method and system may be used for storing energy in a geothermal system and recovering both the stored energy as well as thermal energy on demand. The geothermal system may include injection and production wells that are hydraulically coupled in a geothermal energy reservoir that behaves as a confined reservoir system with thermal energy transferring to fluid injected into the injection well and removed via the production well. Injection flow rate, injection pressure, production flow rate, production backpressure, or fluid residence time may be managed to control energy consumption or energy generation profiles of the geothermal system. During an energy storage mode, the injection flow rate exceeds the production flow rate thereby storing energy in the geothermal reservoir. During an energy recovery mode, production backpressure is reduced thereby releasing the stored energy and electricity is generated by removing the thermal energy from the fluid in a heat engine.

Operational protocol sequences for recovering energy from a thermally productive formation are disclosed. Sealing, drilling, multiranging, power production and distribution techniques in predetermined sequences for well formation are utilized to recover energy regardless of thermal gradient variation, formation depth and permeability and other anomalies or impedances

The present disclosure describes a system and a method for generating energy from geothermal sources. The system includes an injection well and a production well extending underground into a rock formation, a first lateral section connected to the injection well and a second lateral section connected to the production well, the first and second lateral sections connected with a multilateral connector, defining a pressure-tested downhole well loop within the rock formation and in a heat transfer arrangement therewith. The downhole well loop cased in steel and cemented in place within the rock formation. The downhole well loop to receive working fluid capable of undergoing phase change between liquid and gas within the downhole well loop as a result of heat transferred from the rock formation. The system also includes a pump to circulate working fluid, a turbine system to convert the flow of working fluid into electricity, and a cooler.

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.

A geothermal system is used for obtaining heated heat transfer fluid, such as steam, via heat transfer with an underground reservoir of magma. The geothermal system includes a wellbore extending between a surface and into an underground chamber formed in a reservoir of magma. The chamber may be formed by injecting a fluid at an increased pressure into underground magma to form a cavity that acts as the underground chamber.

Wellbore for extracting heat from magma and a corresponding method. The method includes the steps of drilling a borehole from a surface and towards a magma chamber; supplying a drilling fluid to an interface between a drill bit and a terminal end of the borehole during drilling; terminating the drilling in response to the borehole achieving a predetermined depth; and supplying a thermodynamic fluid into the borehole to maintain the borehole while completing the wellbore. The drilling fluid lifts cuttings out of the borehole and quenches magma to form a solid phase material that can be cut by the drill bit.
