Method and apparatus for using geothermal energy for the production of power

Apparatus for enhancing the flow of geothermal fluid from at least one injection well to at least one production well, which comprises:

• a. A first, horizontal geothermal well, which is used as said injection well into which water is injected,
• b. A second horizontal, geothermal well, which is used as said production well 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
• c. Means for producing a water density difference and a pressure difference between said first horizontal, injection well and said second horizontal, production well,
• wherein the first horizontal, injection geothermal well has an open slotted outlet, from which injected water flows into the geological layer in which the well has been drilled, and the second horizontal, production geothermal well has an open slotted inlet, whereby geothermal fluid flows into it from the geological layer because of buoyancy of the water and the pressure difference between said horizontal injection and horizontal production wells.

Method for assuring the flow of geothermal fluid from at least an injection well to at least a production well, which comprises the following steps:

• I—Providing a first, horizontal, geothermal well, which is connected to said injection well;
• Il—Injecting water into said injection well;
• III—Providing a second, horizontal, geothermal well, which is connected to said production well;
• IV—Recovering geothermal fluid from said production well;
• V—Generating a water density difference and a pressure difference between said first horizontal well and said second horizontal well by providing a fluid pump connected to said second horizontal well;
• and
• VI. Inducing geothermal fluid into said second horizontal geothermal well from the geological layer because of buoyancy of the water and the pressure difference between the horizontal injection and horizontal production wells.
