Systems And Methods For Multi-Fluid Geothermal Energy Systems

摘要

A method is disclosed for extracting geothermal energy from a geothermal reservoir formation. The method may involve using a production well to extract brine from the reservoir formation. At least one of nitrogen (N2) and carbon dioxide (CO2) may be used to form a supplemental working fluid which may be injected into a supplemental working fluid injection well. The supplemental working fluid may be used to augment a pressure of the reservoir formation, to thus drive a flow of the brine out from the reservoir formation.

1. A geothermal energy production method for extracting geothermal energy from a reservoir formation, the method comprising:
using a production well to extract brine from the reservoir formation; and injecting at least one of nitrogen (N2) and carbon dioxide (CO2) as a supplemental working fluid into a supplemental working fluid injection well and using the supplemental working fluid to augment a pressure in the reservoir formation, to thus drive a flow of the brine, and eventually the supplemental working fluid, up the production well and out from the reservoir formation.
