The simulation models were developed to predict the potential geothermal energy production rates. In addition, the model illustrates a sensitivity analysis on multiple reservoir parameters (i.e. porosity, permeability, thermal conductivity, well spacing, etc.). Hence, the effect of these parameters on the potential geothermal energy production rates determines the viability of the project by measuring the lifetime costs. A simulation model was built to obtain preliminary results of the sensitivity analysis for the Volve oil field, located 200 kilometers west of Stavanger at the southern end of Norway. Volve field is mainly formed by a sandstone formation located at a depth between 2750–120 meters below the sea level. Based on outcomes derived from the sensitivity analysis, the petrophysical properties such as porosity, and permeability had lower effects in enthalpy production. While, well spacing stands out as the foremost influential parameter impacting the production of geothermal energy and has a significant impact on well production enthalpy.
