RESIDUAL WATER SATURATION OF AN OIL RESERVOIR REDUCED USING GBA-F MULTIFUNCTIONAL COMPOSITION

This paper describes the study of a method for controlling the physical and chemical properties of an oil reservoir in order to increase its oil recovery by injecting a GBA-F acid composition into the reservoir. An experimental testbed is developed to physically simulate the effect of the acid composition on the oil reservoir. Experiments are carried out using the flat model with a single injection of the reagent into the central wellbore. Experimental results confirm the effectiveness of the acid composition.
