The mixing rules are used in the cubic equations of state to determine the values of the attractive force parameter, a, and the repulsive force parameter, b, mixtures. The mixing rules are applied here to reservoir fluids. It was discovered that parameter a should not be treated as a constant since it varied significantly with pressure. It was therefore regressed by two straight lines, and the resulting equation of state gave a very good fit to PVT data of reservoir fluids.
