Abstract. In this paper we will focus on a promising technology of thermochemical treatment using the energy of the exothermic reaction of the interaction of two inorganic salts pumped into the reservoir in the form of an aqueous solution. The technology is environmentally safe and effective for intensification of production at low-yield wells of "old" layers and for low-permeable layers of unconventional high-viscosity oil. The authors created a mathematical model of the process and conducted a series of numerical studies that form the basis of field experiments to test technology at various fields in Russia.
