Abstract

A process-based multiscale network modeling approach is introduced to predict the drainage capillary pressure and relative permeability-wetting phase saturation curves at early cementation, final cementation and feldspar dissolution of the Wilcox tight gas sandstone. Predictions based on a two-scale analysis of an X-ray tomographic image are conducted as well but computational limitations make conclusions uncertain in this paper. We emphasize process-based modeling informed from thin sections as a cheap method of making a priori predictions of tight gas sandstone transport properties at various times in the paragenesis.
