Beschreibung
Zusammenfassung:	The present invention relates to systems and methods of intelligently extracting heat from geothermal reservoirs. One geothermal well system includes at least one injection well extending to a subterranean formation and configured to inject a working fluid into the subterranean formation to generate a heated working fluid. At least one production well extends to the subterranean formation and produces the heated working fluid from the subterranean formation. A production zone defines a plurality of production sub-zones within the subterranean formation and provides fluid communication between the at least one injection well and the at least one production well. Each production sub-zone is selectively accessed in order to extract heated working fluid therefrom and thereby provide a steady supply of heated working fluid to the surface.
