Description
Summary:At the Institute of Petroleum Chemistry, SB RAS, to solve enhanced oil recovery problem, new deep eutectic solvents (DES) are being developed using complexes of polybasic acids and Lewis acids with coordinating solvents, carbamide and polycyclic amine. Based on the principles of “green chemistry”, an acid oil-displacing composition GBK with prolonged action based on surfactants, adducts of an inorganic polybasic acid, polyol and carbamide was created. The results of laboratory research and pilot testing of EOR technology using acid composition are presented. It is promising to use on industrial scale the low-solidifying acid compositions based on DES with controlled physicochemical, surfactant and rheological properties to enhance oil recovery in a wide range of climatic conditions, including the northern regions and the Arctic.
