The purpose of this study is to obtain the heat extraction of the supercritical CO2 in the reservoir for the EGS. The heat transfer model conjugated with the Darcy's law employed by the finite element package is used to obtain the thermal behavior in the porous medium. The sensitivity parameter study under the various inlet velocities and porosities of the porous medium are discussed. The results show that the inlet velocity is the most important effect for the heat extraction. The temperature of exit decreases as the inlet velocity increases apparently. It means that the heat extraction will increase as the velocity decreases. However, it is evident gradually as the porosity decreases. This study can enhance the heat extraction and reduce the cost of realistic test of enhanced geothermal system.
