Abstract
A system and process for extracting geothermal energy from a geologic formation. Coolant fluid is introduced into a first fracture system. The first fracture system is at a first height in the formation. The coolant fluid is collected from a second fracture system. The second fracture system is at a second height in the fracture system. The second height is lower than the first height. Coolant fluid introduced into the first fracture system percolates through the geologic formation from the first fracture system to the second fracture system, collecting heat from the geologic formation.
