Recovery percentages from light oil reservoirs range from 5% for difficult oil to 50% for light
oil in highly permeable sandstone reservoirs. Other reservoirs contain oil that is too difficult
to produce with conventional means. One of the methods to recover oil from medium and
low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case
the oxygen in the air burns the heavier components of the oil, generating a heat wave
leading to vaporization of lighter components. In this work, we consider a simple model for …
