B02 Pilot Tests of IOR-Technology Alternating Thermal-Steam and Physicochemical Treatments of High-Viscosity Oil Pools with oil-displacing systems L.K. Altunina* (Russian Academy of Sciences) SUMMARY To increase efficiency of thermal-steam and cyclic-steam treatments of high-viscosity oil pools we propose to combine them with physicochemical methods. Therefore IOR-technology has been developed to alternate thermal-steam and physicochemical treatments of high-viscosity oil pools with oil-displacing systems to improve oil recovery. Oil-displacing systems contain surfactants and at thermal stimulation they generate CO2 and alkaline buffer solution in situ. Use of such systems decreases oil viscosity interfacial tension and clay swelling and simultaneously increases mobility of
