The paper describes a numerical technique that simulates 2-dimensional heat transfer and one-dimensional, 3- phase flow in a multilayered reservoir.Interphase mass transfer accounts for steam condensation, solution-gas drive, distillation, and solvent extraction. The mathematical development and the various features of the model are presented, and computer calculations on several test problems show a close agreement of the model with analytical solutions, laboratory experiments, and field data. The major advantages of this stimulation model over previous models are increased speed and reliability with no sacrifice of physical significance. These advantages stem from an implicit pressure-explicit saturation formulation, simultaneous solution of pressure and energy equations, and improved technqiues for invoking phase constraints and calculating mass transfer terms. The model is a valuable tool for studying steam stimulation and other thermal processes. The model can be easily extended to treat 2- and 3-dimensional configurations and to include other phenomena such as capillary pressure, temperature dependence of relative permeability, and in situ combustion.
