摘要：
Gas injection is one of the most common heavy oil recovery methods. In this study, effect of viscosity reduction of heavy oil on its recovery and production rate during gas injection were investigated. In this regard, governing equations such as continuity and stokes equations were solved using finite element method with assuming specified initial and boundary condition. Numerical results show that production rate for gas injected heavy oil is 50 times higher than that of heavy oil without considering gas injection. Also, simulation results demonstrate the location of high pressure drop zones in porous media.
