Investigating Spontaneous Capillarity-Controlled Events Via the Level Set Method

SIAM Computational Science & Engineering Conference, Costa Mesa, CA, February 21, 2007



An accurate description of the mechanics of pore level displacement of immiscible fluids could significantly improve the macroscopic parameter predictions from pore network models in real porous media. Assuming quasi-static displacement, we describe a simple but robust model based on the level set method for determining critical events for throat drainage and pore imbibition. The method arrives at geometrically correct interfaces while robustly handling topology changes and is independent of the pore space complexity.
