Multiple Well Open System (Magmatic/ Volcanic/Granitic Intrusion)

  • Much higher enthalpy solutions may be possible from Multiple Well Open Systems in hot rock formations associated with magmatic, volcanic, or granitic intrusion structures;
  • Both types of Geothermal reservoirs are possible: Petrothermal (hot dry rock with fractured rock providing the permeability pathways for surface heat transfer fluids to be circulated) and Hydrothermal (hot wet rock with fractured rock already filled with mineralised and/or meteoric water able to be circulated);
  • As with other multiple well solutions, there would be some number of injection and production wells.
