C12 IMPROVED THERMAL-STEAM TREATMENT OF HIGH-VISCOSITY OIL POOLS BY СО2 GENERATING SYSTEMS Abstract 1 A novel technology has been developed to enhance oil recovery from reservoirs containing highviscosity oils. The technology combines thermal-steam and physico-chemical treatments using surfactant-based systems which are capable to generate СО2 and alkaline ammonium buffer solution in situ. Pilot tests of EOR technology were successfully carried out both in Russia and China. In Russia 264 m 3 of 50 % solution of oil-displacing system were injected into three steaminjection wells in the area of Permocarbonic high-viscosity oil pool Usinskoye oil field. In 1-3 months the production
