SYSTEMS FOR GENERATING ENERGY FROM GEOTHERMAL SOURCES AND METHODS OF OPERATING AND CONSTRUCTING SAME

Resumen de: AU2023365990A1

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.

Method of controlling tensile-splitting and hydro-shearing parameters during completion of enhanced geothermal system wells

Resumen de: GB2634155A

Methods and systems for geothermal energy production wherein multiple horizontal or vertical wells are used to pass fluids through the Earth from an injector well 215 to a producer well 210 through induced cracks, splits, fractures, conduits, or channels in the rock. Such methods and systems include controlling tensile-split conduits in a subterranean geothermal formation by providing an injection well, providing a production well, configuring the injection well for injection of a tensile-splitting fluid into a production zone, configuring the production well to produce a heated fluid from the production zone, applying pressure to the production well, creating a plurality of tensile-split conduits, raising or lowering the pressure in the production well, establishing fluid communication between the injection well and the production well using hydro-shearing, and producing the heated fluid to the surface.

用于减少排放的能源和资源提取的系统和方法

Resumen de: US2025067481A1

A heat extraction system for extracting heat from a reservoir, the system including a co-axial tool configured to be placed underground, the co-axial tool having an outer pipe and an inner pipe located within the outer pipe, each of the outer pipe and the inner pipe being connected to a shoe so that a fluid flows through an annulus defined by the inner and outer pipes, reaches the shoe, and flows through a bore of the inner pipe; and a power generator fluidly connected to a chemical processing unit to receive a fluid, and also fluidly connected with a first port to the inner pipe and with a second port to the outer pipe of the co-axial tool. A temperature difference of the fluid at the power generator and at the co-axial tool drives the power generator to generate energy.
