Application of the GBK-F multifunctional composition to reduce the residual water saturation of oil bed

A method for controlling the physical and chemical properties of a formation in order to increase its oil recovery by injecting an acid composition GBK-F into the formation is being considered. An experimental setup has been created for physical modeling of the effect of the composition on an oil reservoir. Experiments were carried out on a flat model with a single injection of the reagent into the central well. The experimental results confirmed the effectiveness of the composition.
