Abstract: The oil recovery from reservoirs formed of more subsurface rock formations can be hindered by the variability of the rocks permeability. This element can strongly influence the oil recovery and the efficiency of the drainage process. In order to understand this phenomenon and to propose a technical solution thereafter, the simulation of an ascending air phase flow in a saturated vertical porous channel, composed of two layers with different permeabilities is done. The numerical study is performed in order to evaluate the effect of injected air mass flow rate, the effect of the porous column width and their permeability variations. The results show that some regions in the channel are not correctly drained due to high pressure losses in those regions.
Keywords: Two-phase flow, Pressure drop, Recovery process, Stratified porous matrix, Saturation behavior.
