Role of Phase and Kinetics Models in Simulation Modeling of In Situ Combustion

Based on a review of recent foreign publications, we examine the typical features in simulation modeling of in-situ combustion of high-viscosity crude oils and natural bitumens. We pay special attention to phase and kinetics models, and also examine the differences between combustion of heavy and light oils. We formulate approaches and describe important aspects on which we need to focus when comparing models.
