The formation of the in situ combustion front for thermogas method was investigated. The influence of the value of oxygen diffusion coefficient on the thickness and the formation time of the front were studied. Mathematical model based on the equation of reaction-diffusion-advection and thermohydrodynamical simulator CMG STARS were used to describe processes. In this paper we propose analytical formulas for estimating the time of formation and the thickness of the combustion front.
