Abstract

This paper presents the field tests results of the combined application of chemical compositions with various functional purposes, gel-forming, intensifying and oil-displacing, in combination with thermal methods of oil recovery. A complex application, in combination with other technologies, of an acid oil-displacing and intensifying composition with prolonged action based on surfactants, inorganic acid adducts and polyatomic alcohol is considered. Field tests were carried out on the Permian- Carboniferous reservoir of the Usinsk high-viscosity oil field, Komi Republic, Russia. The results of two treatments are presented: a hot water injection horizontal well and a production cyclic steam stimulated (CSS) well. It is concluded that it is necessary to combine various methods of enhanced oil recovery to achieve higher efficiency
