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. The combustion mechanisms are different for light oils, where evaporation is dominant, whereas for medium non-volatile oils combustion is dominant. It is our goal to study the relative importance of evaporation, by studying a two component mixture of volatile light and non-volatile oil. The numerical calculations make it possible to estimate the bifurcation points, where the character of the combustion changes from an evaporation dominated process to a combustion dominated process.
