A numerical mathematical model is described on the steam-flood process which depends on fewer restrictive assumptions than models previously reported, but the solution of which is economically obtained. Example calculations are presented which, on comparison with experimental results, tend to validate the model. Results which expose certain process mechanics are discussed. The model describes the simultaneous flow of 3 phases--oil, water, and gas--in one dimension. It includes the effects of 3-phase relative permeabilities, capillary pressure, and temperature- and pressure-dependent fluid properties. Interphase mass transfer of water-steam is allowed, but the oil is assumed nonvolatile and the hydrocarbon gas insoluble in the liquid phases. The model allows heat convection in one dimensional and 2-dimensional heat conduction in a vertical cross section spanning the oil sand and adjacent strata. The hydrocarbon-steam gas composition is tracked, but the effect of gas composition on water-steam phase behavior is neglected. The model is solved numerically in 3 separate stages. (12 refs.)
