Effect of treatment of an injection well of the Usinskoye oilfield with acid GBK composition on the oil recovery and properties of produced fluids
An acid composition of prolonged-action based on an inorganic acid adduct, a polyol and a surfactant has been developed at the Institute of Petroleum Chemistry, SB RAS. Introduced into the injection well, the composition exerts a prolonged positive effect on the oil recovery in the area of its influence. The increase in oil production rates and decrease in water cuts are accompanied by changes in viscosity of extracted oil and mineral composition of produced water. The appearance of components of a new composition and products of its hydrolysis in the produced fluids suggests the inclusion of still virgin zones, changes in filtration flows, and desorption of heavy-oil components from reservoir rock after its break-up.An acid composition of prolonged-action based on an inorganic acid adduct, a polyol and a surfactant has been developed at the Institute of Petroleum Chemistry, SB RAS.
