Abstract
An enhanced geothermal system includes a first well and a second well drilled through a subterranean formation. The first well includes a lateral section extending through a heat zone in the subterranean formation. The second well is a U-shaped well having a first lateral section extending through the heat zone on a first side of the lateral section of the first well, and a second lateral section extending through the heat zone on a second side of the lateral section of the first well.
Claims11
An enhanced geothermal system, comprising:
- a first well drilled through a subterranean formation and including a lateral section extending through a heat zone in the subterranean formation;
- and
- a second well drilled through the subterranean formation proximate the first well, the second well being a U-shaped well having:
- a first lateral section extending through the heat zone on a first side of the lateral section of the first well, and a second lateral section extending through the heat zone on a second side of the lateral section of the first well.
1 more element
A method, comprising:
- drilling a first well through a subterranean formation such that the first well includes a lateral section extending through a heat zone in the subterranean formation;
- and
- drilling a second well through the subterranean formation proximate the first well such that the second well is U-shaped having:
- a first lateral section extending through the heat zone on a first side of the lateral section of the first well, and a second lateral section extending through the heat zone on a second side of the lateral section of the first well.
1 more element
A method, comprising:
- providing a power fluid to a U-shaped well extending through a subterranean formation, the U-shaped well having two lateral sections extending through a heat zone of the subterranean formation;
- injecting the power fluid into the heat zone through perforations in the two lateral sections of the U-shaped well;
- and
- producing heated power fluid from the heat zone through a second well extending through the subterranean formation proximate the U-shaped well.
