Enhanced Geothermal Systems and Methods

摘要

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.

1. A geothermal well system, comprising:
at least one injection well extending from a surface to a subterranean formation and being configured to inject a working fluid into a production zone defined within the subterranean formation and thereby generate a heated working fluid, wherein the production zone has been fractured to enhance fluid conductivity; at least one production well extending from the surface to the subterranean formation; and one or more production flow control devices arranged downhole within the production well to provide access to the production zone and thereby defining a plurality of production sub-zones within the production zone, wherein at least one production flow control device is arranged at each production sub-zone in order to selectively access each production sub-zone in order to extract heated working fluid therefrom and thereby provide a corresponding supply of heated working fluid to the surface.
