Oil displaced by heat fronts associated with Thermal Oil Recovery methods is calculated using a graphical correlation of three-phase permeability data. Previous investigations were based on the two-phase flow of steam and oil behind the heat front and hot water and oil ahead of the condensation front. In situ combustion displacement has not been adequately studied, except to some extent by numerical methods and laboratory experiments, due to the complexity of gas, oil and water three-phase flow. The solution developed herein combines fluid flow with Marx-Langen-heim heat loss to predict heat front velocity and oil displacement.
