The linear displacement of a wetting fluid by an immiscible non‐wetting fluid in a two‐dimensional porous medium composed of a network of sites multi‐connected by bonds has been simulated mathematically. The algorithm involves Monte Carlo decision making, random walks and principles of the percolation theory. The algorithm described in the present work successfully predicts the three distinct behaviours of immiscible displacement in porous media. This algorithm is tested against experiments available in the literature for two‐dimensional porous media. The agreement between the numerical results and the experiments is very good.
