PORE SCALE MODELING OF TWO-PHASE FLOW

Summary. In this paper, we compare predictions of several pore-scale codes for single- and two-phase flow for the first time. Firstly, two implementations of lattice-Boltzmann method (LBM) and a finite-difference based code (FDDA) predict single-phase flow in Fontainebleau sandstone and dolomite samples. We then obtain pore-scale drainage for two fluid phase configurations using a novel level set method based progressive quasi-static (LSMPQS) algorithm for capillarity dominated flow. The resulting fluid configurations are used to compute relative permeability using LBM in each phase as well as formation factor. We demonstrate that the numerical methods compare well with each other and available experimental results.
