In this report, constitutive relations for fluid-saturated porous media are developed in a format suitable for inclusion in standard hydrodynamic computer codes. In developing the constitutive model, it was assumed that 1 there is no relation motion between the fluid and the solid, 2 no significant heat exchange occurs between the solid and fluid phases and 3 porosity phi is a function of only the mixture pressure P sub c and fluid pressure P sub f. The last two assumptions may not be valid under certain field conditions. These assumptions can, however, be relaxed at the expense of some simplicity.
