Abstract
In present study, we investigate effect of heterogeneity of porous medium on gas saturation after drainage and imbibitions processes. The heterogeneity is modeled with the packed beds layered with different glass beads of grain diameter. The packed beds have two types of heterogeneity in serial and parallel directions with respect to the mean flow. Initial gas saturation is strongly affected by capillary entrance pressure at the interface of heterogeneous porous structures.
