Abstract

See full text

A system and method for geothermal heat production. A balanced geothermal energy transfer loop includes a first wellbore and a second wellbore extending from surface to a subterranean geothermal formation and a plurality of balanced open hole circuits extending between the first wellbore and the second wellbore through the geothermal formation, forming a substantially sealed closed loop. Each of the plurality of circuits is designed or modified to have a substantially equal circuit parameter. The circuit parameter may include one or more of circuit fluid velocity, circuit pressure drop, circuit volume and/or circuit length. The circuit parameter may include circuit length and volume, and the circuits connect the supply/return wells in a first out/last in configuration.
