ABSTRACT:
An apparatus and method for enhancing the flow of geothermal fluid from at least one injection well to at least one production well, which comprises a first horizontal geothermal well, which is used as the injection well, and into which water is injected; a second horizontal, geothermal well, which is used s the production well and from which geothermal fluid issues, wherein the second, horizontal, production, geothermal well is substantially horizontally and vertically spaced from the first, horizontal, injection, geothermal well and located at a shallower depth than the first, horizontal, injection, geothermal well; and the apparatus form producing a pressure difference between the first horizontal, injection well and the second horizontal, production well and utilizing the water density difference induced by the temperature difference. Preferably, binary geothermal power plants or combined cycle geothermal power plants can be used to produce power from geothermal fluid recovered from the production well.
