Enhanced geothermal systems and methods

A method of extracting thermal energy from a subterranean formation, comprising:

• injecting a working fluid from at least one injection well into a production zone defined in a subterranean formation, the at least one injection well extending from a surface and the production zone being fractured to enhance fluid conductivity;
• circulating the working fluid within the production zone in order to generate a heated working fluid;
• selectively accessing the production zone via at least one production well extending from the surface, the at least one production well having one or more production flow control devices arranged therein downhole and thereby defining a plurality of production sub-zones in the production zone,
• wherein each production flow control device is arranged at each production sub-zone;
• determining a property of the heated working fluid as extracted from a corresponding one of the plurality of production sub-zones using one or more sensors of the one or more production flow control devices, and selectively actuating the one or more production flow control devices based upon the determined property falling below a predetermined threshold;
• and
• producing the heated working fluid from the plurality of production sub-zones to the surface via the at least one production well and thereby providing a corresponding supply of heated working fluid to the surface.

A geothermal well system, comprising:

• at least one injection well extending from a surface and through a subterranean formation, the at least one injection well being configured to inject a fluid into a production zone defined within the subterranean formation and thereby generate a heated working fluid, the production zone being fractured to enhance fluid conductivity;
• at least one production well extending from the surface and to the subterranean formation, the at least one production well being configured to produce the heated working fluid from the production zone to the surface;
• one or more lateral production wells extending from the at least one production well and into the production zone;
• and
• one or more production flow control devices arranged downhole within in each lateral production well and being selectively actuatable to provide access to the production zone and thereby define a plurality of production sub-zones within the production zone,
• the plurality of production sub-zones being configured to provide fluid communication between the at least one injection well and the at least one production well and thereby provide a corresponding supply of heated working fluid to the surface and
• the one or more production flow control devices comprising one or more sensors to determine a property of the heated working fluid as extracted from a corresponding one of the plurality of production sub-zones, and the one or more production flow control devices being selectively actuatable based upon the determined property falling below a predetermined threshold.
