System and method for harvesting geothermal energy from a subterranean formation

A method of harvesting a fluid from a subterranean formation, comprising:

• positioning a plurality of sleeves in an injection wellbore that extends into the subterranean formation, the plurality of sleeves each being spaced apart within the injection wellbore and threadably connected to a casing string, each sleeve of the plurality of sleeves being selectively actuatable at least between a first position and a second position, wherein a sleeve of the plurality of sleeves is annularly isolated by an external casing packer within the injection wellbore;
• fracturing the subterranean formation in a plurality of locations proximate to the plurality of sleeves to enhance a plurality of fluid pathways between the injection wellbore and at least one producing wellbore that extends into the subterranean formation, wherein each location of the plurality of locations corresponds to a respective sleeve of the plurality of sleeves, wherein when the respective sleeve is in a respective one of the first position and the second position a fluid pathway of the plurality of fluid pathways extends from the respective sleeve to the at least one producing wellbore;
• injecting a first fluid down the injection wellbore such that the first fluid flows into a first respective fluid pathway of the plurality of fluid pathways;
• and
• producing a second fluid from one or more of the injection wellbore and the at least one producing wellbore, wherein fluid within a second respective fluid pathway of the plurality of fluid pathways is produced as the second fluid via in-situ stresses within the subterranean formation while the first fluid flows into the first respective fluid pathway.
