- •
Energy consumption to construct EGS (Enhanced Geothermal Systems) well systems is modeled and calculated.
- •
Flow and heat transfer of the geofluid in EGS wells are modeled and calculated.
- •
Design guidance for EGS well systems is proposed based on the energy analysis.
- •
The calculated EROI (energy return on investment) for the proposed EGS well systems was 33.8 to 286.2.
