Claim 13:
14. A system for harvesting geothermal energy from a subterranean formation and extracting said harvested geothermal energy at a surface location, comprising:
an injection wellbore provided in the subterranean formation;
a plurality of selectively opening sleeves positioned in the injection wellbore and spaced apart within the subterranean formation, each of said plurality of selectively opening sleeves having an open position to inject fluid into the subterranean formation and a closed position to prevent the injection of said fluid into the subterranean formation, wherein at least some of said plurality of selectively opening sleeves are coupled to and in line with a casing string within the injection wellbore, and wherein at least some of said plurality of selectively opening sleeves are encased in cement prior to a fracturing of the subterranean formation; and
at least one producing wellbore provided in the subterranean formation in a predetermined location proximate to said injection wellbore, wherein said cement encasing said selectively opening sleeves and the subterranean formation are fractured in a plurality of locations proximate to said plurality of selectively opening sleeves to enhance a fluid pathway between said injection wellbore and said at least one producing wellbore when said plurality of selectively opening sleeves are in the open position, wherein said at least one producing wellbore is configured to produce a heated fluid at a second temperature higher than a first temperature of said injected fluid.
