Abstract
Systems and methods for maximizing energy recovery from a subterranean formation are herein disclosed. According to one embodiment, a selected subterranean open-hole interval is isolated and at least one fracture is stimulated in the isolated subterranean open-hole interval.
Claims15
A method for recovering thermal energy from a subterranean formation comprising:
- pressurizing at least one unstimulated fracture within an unisolated subterranean open-hole interval to create a first stimulated fracture;
- isolating a selected subterranean open-hole interval by blocking the first stimulated fracture with a temporary fracture sealant, wherein the temporary fracture sealant thermally degrades at geostatic temperatures;
- and
- pressurizing at least one unstimulated fracture within the isolated subterranean open-hole interval to create a second stimulated fracture, wherein a water is circulated within the second stimulated fracture to be heated and produced from the well for generating electricity.
