ABSTRACT
Geothermal resources consist of thermal energy from the earth’s interior stored in both rock and trapped steam or liquid water. Geothermal energy is classified as a renewable resource because the heat from an active reservoir is continuously restored by natural heat production, conduction and convection from surrounding hotter regions, and the extracted geothermal fluids are replenished by natural recharge and injection of the cooled fluids (Goldstein et al., 2011).
