Abstract

We develop and analyze a novel, quasi-static, pore-scale approach for modeling drainage in a porous medium system. The approach uses: (1) a synthetic, non-overlapping packing of a set of spheres, (2) a discrete representation of the sphere packing, and (3) concepts from pore morphology and local pore-scale physics to simulate the drainage process. The grain-size distribution and porosity of two well-characterized porous media were used as input into the drainage simulator, and the simulated results showed good agreement with experimental observations. We further comment on the use of this simulator for determining the size of a representative elementary volume needed to characterize the drainage process.
