Nowadays, developing unconventional oil resources generates considerable interest in modern society due to the depletion of conventional oil resources. Heavy oil is widely believed to be the most important unconventional resource because of its tremendous reserves around the world. However, the exploitation of this type of energy source is still complicated in both recovery and transport stages due to their high viscosity and density, in addition to having a high content of resins and asphaltenes. Thus, to improve the production of heavy oil, experts have always considered thermally enhanced oil recovery to be a potential and promising approach for these purposes. Indeed, the thermal energy resulting from the application of thermally enhanced oil recovery contributes to heay oil viscosity reduction, in addition to reducing the amount of asphaltenes and resins as well. The next decade is likely to witness a rise in the application of thermally enhanced oil recovery methods for heavy and extra-heavy oil reservoirs. However, the characteristics of thermally enhanced oil recovery have not been addressed in detail. Thus, to improve these technologies, many researchers are considering the application of catalysts to be one of the main efficient approaches for decreasing heavy oil viscosity and hence facilitating its transportation. It is common knowledge that oil-soluble transition-metal-based catalysts play an important role in the heavy oil oxidation and pyrolysis reactions, in which they could decompose in situ and form active species in reservoir conditions in the form of nanoparticle suspensions or emulsions, leading to enhanced heavy oil recovery from these formations. These types of catalysts supposedly play the same role in downstream processes involving heavy oil processing by decreasing the amount of resins and asphaltenes content in the presence of hydrogen. Moreover, there is still be a wide gap in our knowledge about the mechanisms generated by injecting catalysts into the reservoir in a porous mineral medium and the role of the mineral surface as an active component of the catalytic complex. Thus, it is possible to use dispersed slurry systems and supported catalysts on specially selected carriers for better understanding. The present special issue is devoted to studying the problems related to catalysts synthesis, their formation, structure, and stability during heavy oil conversion during upgrading.

Title: Iron tallates effect on heavy oil aquathermolysis in mild conditions

Abstract: Currently heavily developed light oil resources are being depleted, and the energy consumption is increasing. In this context, the task of developing the tight oil reserves is relevant and will soon become an essential resource for stabilizing and increasing the oil production. The share of tight oil (including heavy crude oil) is steadily increasing in the overall balance. Oil production will therefore be at the expense of these oil revenues in the coming years. These hydrocarbon resources are referred to as non-traditional, as they require the use of technologies and methods that differ from traditional methods of producing light oil. One such method is the thermal steam treatment of formation. It is characterized by the injection of the calculated volume of the heat carrier through the injection wells, the creation of a thermal rim and its subsequent movement using the unheated water in the reservoir towards the wells. However, the use of various complementary techniques, such as the injection of catalytic systems, will increase energy efficiency and intensify the recovery of heavy oil. The relevance of such research is unquestionable. This work has examined the structural changes in the interchangeability of the alternative oil contained in the oil-bearing sandstone sample, with impact on the latest process of catalytic and non-catalytic aquathermolysis. The sandstone specimen is taken from the Volga-Ural Province (Russia).
