Abstract In the attempt to achieve optimal recovery of petroleum from a reservoir, it is usually necessary to model numerically the fluid displacements within the reservoir. These displacements often involve the propagation of steep fronts, such as those between different fluids or between regions of differing chemical concentrations. Such fronts generally pose difficulty for numerical methods, the overcoming of which has stimulated the development of new methods in recent years. We discuss our recent work on one such method, the random choice method, which has the inherent capability of following even perfectly sharp fronts. The use of the method is illustrated for multi-dimensional, two-phase, immiscible porous flow, including the effects of capillary pressure and of gravity.
