ABSTRACT:
The present invention performs numerical simulation of surfactant flooding during enhanced oil recovery of a given hydrocarbon reservoir. The present invention utilizes an improved method for determining relative permeability while maintaining physical consistency when the phase behavior varies between different phase Types. This new relative permeability model maintains the physical consistency in the transition from Type II(−) to Type III to Type II(+) systems and vice versa.
