Study of the effect of a chemically evolving oil-displacing composition on the displacement of heavy crude oil

This work presents the results of the laboratory tests of new physicochemical technologies for enhanced oil recovery of heavy crude oil under natural conditions of development using oil-displacing ‘smart’ systems. The systems are based on surfactants and buffer systems. Their rheological and acid-base properties can be regulated by their chemical evolution directly in the formation. The results of studying the oil-displacing ability of new physicochemical technologies are presented.
