Recently, there has been an increased / growing interest on the part of the oil industry in the development of thermal methods of impact on the reservoir, which have great potential in terms of production of hard-to-recover reserves of oil-producing rocks and heavy oil fields. The use of such technologies is accompanied by a wide variety of nonlinear geomechanical and geochemical sub-processes. The need to create predictive numerical / mathematical models in this case is due to the significance of each individual subprocess and the large differences in the characteristic time and spatial scales of each of them, which makes it difficult to describe the full process of applying the technology through laboratory experiments only. Thermal methods of enhanced oil recovery include, for example, the initiation of a mobile front in the reservoir of partial combustion of hydrocarbons, accompanied by the release of a large amount of heat, by pumping air under high pressure. The positive effect of this effect is due to the formation of a large number of gaseous combustion products and steam that displace liquid hydrocarbons (thermogasic effect), as well as an increase in the intraplate temperature and pressure as a result of oxidative reactions, which, under the right conditions, can cause thermal degradation of kerogen and bitumen.
