B03 Pilot Tests of Gel-Technology for Water Shutoff V.A. Kuvshinov* (Russian Academy of Sciences) SUMMARY Thermal-steam treatment of oil pool by means of stationary or cyclic steam injection is considered as the most effective out of all current methods for high-viscosity oil production. However problem consists in low coverage by steam injection and decreased efficiency of thermal-steam treatment at later stage of oil field development. We propose to increase efficiency of thermal-steam treatment combining it with physicochemical methods using gel-forming and oil-displacing systems. Gels increase coverage by steam injection and oil-displacing systems provide extra displacement of oil. Technologies have been
