Conductivity Problem

The scaling relations for the fluid permeability in percolation structures are numerically studied using both of the coarse numerical grid and the refined numerical grid. We suggest that the permeability for viscous fluid flows in two-dimensional lattice percolation porous media be equivalent to the conductivity problem in percolation theory, independent of the simulation refinements. The refined numerical grid does not lead to the new universality.

We develop our existing two-dimensional lattice-gas model to simulate the flow of single phase, binary immiscible and ternary amphiphilic fluids. This involves the inclusion of fixed obstacles on the lattice, together with the inclusion of "no-slip" boundary conditions. Here we report on preliminary applications of this model to the flow of such fluids within model porous media. We also construct fluid invasion boundary conditions, and the effects of invading aqueous solutions of surfactant on oil-saturated rock during imbibition and drainage are described.
