Insights into the Mechanisms of Oil Recovery in a Hybrid Steam and Combustion Process

This work shows that the proposed reaction kinetics model is able to capture the key chemical reactions in an ISC process. It can reasonably predict oxidation behaviour under a wide temperature range. Three combustion reactions were included in the HTO, namely LightOil combustion, Gas Combustion, and Coke combustion. Both combustion front velocity and temperature profiles were well matched. Displacement mechanisms in the hybrid steam combustion processes were captured and simulated in the combustion tube simulation. Dynamical gridding has been applied in the field scale modelling of the hybrid process and combustion fronts can be captured with fine grids.
