An improved numerical simulator for different types of flows in porous media

Abstract

We develop an improved numerical simulator for subsurface compressible flows through porous media with point sources and sinks, which are governed by different equations of state. Computational experiments show that the simulator can generate stable simulation for different types of incompressible or compressible flows involving light or heavy components in porous media with point sources and sinks, large mobility ratios, discontinuous permeabilities and porosities, and anisotropic dispersion in tensor form, even though very large time steps and spatial grids are used.
