Nitrogen-water relative permeability of a fractured geothermal rock was compared to that of porous media in this study. Relative permeability values were measured from a series of steady state experiments. It was verified that the relative permeability of porous media such as Berea sandstone follows the Corey model. On the other hand, nitrogen-water relative permeability points of fractured geothermal rock were found to be higher than that predicted by the Corey Model but lower than that of the X-Curve model. The resistivity method was used to measure saturation while performing flow experiments on the geothermal rock.
