An accurate description of the mechanics of pore level displacement of immiscible fluids could significantly improve the macroscopic parameter predictions in real porous media. Assuming quasi‐static displacement, we describe a simple but robust model based on the level set method for determining fluid interface position for both drainage and imbibition. The method arrives at geometrically correct interfaces while robustly handling topology changes and is independent of the pore space complexity. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
