... of the geothermal reservoir equations: Two-phase (water, steam) flow and phase behavior, Flow in the rock matrix is described by Darcy's law while considering gravity, Capillary pressure is neglected, The pressure-volume work is ignored, which means that the internal energy is equal to the enthalpy...

... to oil ratio (GOR), surface tension, liquid density, and fluid enthalpy. Typically, improving accuracy of these properties will increase the prediction of multiphase models significantly. For example, error in the temperature prediction can be reduced from 10 C to 1 C, pressure uncertainties from 25...
