Percolation Model of Steady State Multiphase Flow in Porous Media

Description of multi-phase transport in actual rocks is based on the determination of the effective macroscopic properties for micro heterogeneous media. In practice these properties are determined mostly through direct experiments which are rather cumbersome and time consuming. At the same time, simple theoretical models, like that of infinite cylindrical pores, are too inaccurate and insufficient to describe and explain many of the experimental data. To develop a more adequate theoretical description of multiphase transport at the micro-level, one should use the network models of the pore space structure and the percolation methods for analysis of these models, including the necessary calculations.
