The Modeling and Simulation of the IWAG Process in Petroleum Reservoirs

摘要

Application of an immiscible water alternating gas (IWAG) method in enhanced oil recovery process was investigated in this article. A black oil model was employed to reach the final equations required for estimation of pressure and saturation domains. The governing equations were discretized using a finite volume method. An implicit pressure-explicit saturation formula was employed to solve the equations. The system equations were solved and related codes were written to simulate the process. Simulation results confirm a higher oil recovery in the IWAG technique when compared to waterflooding and immiscible gas injection processes.
