“…However, this information is not sufficient since it lacks enough data on the effect of the heterogeneous natural structure of the deposit, because it is the latter that can significantly or even radically change the development course of processes, as well as lead to an unpredictable scenario [31][32][33][34]. It should be noted that the initial ignition strongly depends on the properties of crude oil, and, accordingly, each oilfield will have its own low-temperature and high-temperature oxidation (oil cracking) zones, not to mention the required amount of supplied air that will be needed to maintain effective combustion [50][51][52].…”

“…To begin with, when scientists started investigated the origin of oil, they focused on the study of clay minerals, since they are the main constituent elements of oil-producing rock refuse that can generate and store oil. The presence of these minerals has an important influence on the properties of the deposit, namely, on its parameters, such as porosity and permeability [52,70]. In addition, clay minerals in oil-bearing rocks are very important, not only for assessing the quality of formation, but also for assessing the hydrocarbons' displacement and movement, which is extremely important when oil is displaced in the reservoir [71].…”

Global estimates for our remaining capacity to exploit developed oil fields indicate that the currently recoverable oil (light oil) will last for approximately 50 years. This necessitates the development of viscous and superviscous oil fields, which will further compensate for the loss of easily produced oil. In situ combustion is the most promising production method, which allows for increased oil recovery from a reservoir. This being the case, this study provides an overview of global trends regarding the research and implementation of the method under consideration, in order to promote understanding of its applicability and effectiveness. The background to the development of the method is discussed in detail, illustrating the growing interest of researchers in its study. Cases of both successful as well as inefficient implementations of this method in real oil fields are considered. The main focus of the article is to investigate the influence of the parent rock and catalysts on the combustion process, as this is a new and actively developing area in the study of enhanced oil recovery using in situ combustion. Geological surveys, in addition to experimental and numerical studies, are considered to be the main methods that are used to investigate processes during in situ combustion. The analysis that we carried out led us to understand that the processes which occur during the combustion of heavy oil are practically unpredictable and, therefore, poorly understood. The specificity of the oil composition under consideration depends on the field, which can lead to a change in the required temperature regimes for its production. This indicates that there exists multiple specific applications for the method under consideration, each requiring additional full studies into both the fractional composition of oil and its reservoirs. The article also considers various technologies for implementing the in situ combustion method, such as ND-ISC, THAITM, COSH, CAGD, and SAGD. However, the literature review has shown that none of the technologies presented is widely used, due to the lack of an evidence base for their successful application in the field. Moreover, it should be noted that this method has no limits associated with the oil occurrence depth. This technology can be implemented in thin reservoirs, as well as in flooded, clayey, sandy, and carbonate reservoirs. The review we have presented can be considered as a guide for further research into the development of global solutions for using the proposed method.
