Multiphase flow simulation in physically and chemically heterogeneous media

The multiphase flow simulator, MPS, is developed based on the fractional flow approach considering the fully three phase flow in physically and chemically heterogeneous media. Most existing models are limited to two phase flow when considering the physically heterogeneous media. Also, these models have mostly focused on the water-wet media. A number of factors including variations in aqueous chemistry and mineralogy might affect the wettability change from water-wet to oil-wet media. Furthermore, the wetting of porous media by oil could be heterogeneous, or fractional, rather than uniform due to the heterogeneous nature of subsurface media and the factors that influence wettability. However, in this study, chemically heterogeneous media considering fractional wettability is simulated with MPS.
