“…In Canada, this method ranks second in commercial technology, whose implementation allows the production of about 23 million tons of rock oil. It is these Canadian experiences in the development of heavy oil and rock oil fields that show us that the successful organization of large-scale production is possible only after reasoned conclusions, based on scientific and laboratory studies [16,25]. China faces a number of production problems, because most of the heavy oil reservoirs have already passed the middle or the last stage of steam stimulation, and their throughput capacity has significantly diminished.…”

“…However, the main drawback is that heavy fractions (i.e., cokes) are formed during this process. They begin to burn and, as a result, the process returns to a forward combustion characterized by an overheating, which greatly reduces the oil recovery of the reservoir [25,29]. However, the reverse combustion may have some advantages over the forward combustion for heavy oil reservoirs with lower permeability, or may be used as a method of preheating the reservoir [30].…”

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.
