Nowadays, most oil and gas companies are faced with the challenge of developing fields with hard-to-recover hydrocarbons. As a result, there is a strong focus on improving methods for extracting oil from such fields, particularly by enhancing techniques for influencing low-permeability reservoirs. The most widely known and commonly used technique for treating low-permeability rocks is hydraulic fracturing. Another less commonly used method is the injection of thermochemical fluids. These fluids are typically aqueous solutions of two inorganic salts (a binary system), which react to release significant amounts of gas and heat. The explosive nature of the decomposition reaction has an impact similar to that of hydraulic fracturing. However, for the method to be successful, it is important to use the correct reaction catalyst. In this work, the authors carried out laboratory modeling of the impact of a binary system with a delayed-action activator on rocks.
