Abstract
A natural enhanced geothermal system (NAT-EGS) that uses a hot sedimentary aquifer (HSA) is disclosed. An example method may include pumping, via an extraction well, heated water from an extraction depth of a HSA, wherein the HSA satisfies a threshold geothermal characteristic. The example method may include extracting, via an energy conversion unit, heat from the heated water to capture energy, resulting in cooled water. The example method may include injecting, via an injection well, the cooled water at an injection depth of the HSA, wherein the injection depth is deeper than the extraction depth.
