Several process parameters of efficiency must be taken into account in the process of the creation of liquids for enhanced oil recovery. One of the key factors of the required characteristics of hydrochloric acid is the ability of the additives included in the acid composition to inhibit the reaction of the active agent with the carbonate rock. This deceleration effect is necessary to increase the acid exposure area to the treated zone by forming the largest number of cavities in the reservoir. The effective dosages of the nonionic surfactant «Polinor MP4202» and its ability to inhibit the reaction of a carbonate rock model with hydrochloric acid in its presence have been studied.
