Claim 6:
7. A geothermal well system comprising:
a recovery well extending from the surface of the earth to a subterranean formation and into a radiator zone of the formation that is deeper than a subterranean water reservoir in the formation, the recovery well having a first section extending into the formation from the surface of the earth, a second section extending horizontally from the first section and through the radiator zone, and third upturned section extending upwardly from the second section in a direction toward the subterranean water reservoir and into the subterranean water reservoir;
the upturned section of the recovery well having an end disposed in the subterranean water reservoir and the end is fluidically connected to the subterranean water reservoir such that fluid in the subterranean water reservoir flows into and downwardly in the upturned section and into the second section without the fluid from the subterranean water reservoir exiting the formation;
the second section providing a heat transfer section wherein heat from the radiator zone is transferred into fluid from the subterranean water reservoir as the fluid flows through the horizontally extending section; and
wherein fluid from the subterranean water reservoir is recovered at the surface from the horizontally extending section through the first section.
