Abstract
Laboratory experiments were made where two phase mixture of flashed geothermal brine was injected into a tube filled with porous material. Direct measurements of pressure gradient and mass flow were made and used for calculating the relative permeabilities of the two phases. The results were compared with relative permeabilities calculated from field data using the Shinohara method. The resulting relative permeabilities comply with known relative permeability curves to some extent, where the intrinsic permeability of the porous media accounts for the greatest error factor in the measurements.
