The method of the invention comprises enhancing the flow of
geothermal fluid (water and / or steam and / or mixtures thereof) from at least one
injection well to at least one production well, by the following steps: providing a first, horizontal, geothermal well, which is used as said
injection well; injecting water into said
injection well; providing a second, horizontal, geothermal well, which issued as said production well such that said second, horizontal, production, geothermal well is substantially horizontally and vertically spaced from said first, horizontal, injection, geothermal well and located at a shallower depth than said first, horizontal, injection, geothermal well; recovering
geothermal fluid from said production well; and generating a
water density difference and a
pressure difference between said first horizontal, injection well and said second horizontal, production well. Furthermore, the invention comprises an apparatus 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 said injection well and into which water is injected; a second horizontal, geothermal well, which is used as said production well and from which geothermal fluid issues, wherein said second, horizontal, production, geothermal well is substantially horizontally and vertically spaced from said first, horizontal, injection, geothermal well and located at a shallower depth than said first, horizontal, injection, geothermal well; and means for producing a
pressure difference between said first horizontal, injection well and said 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.
