Gel-technologies for IOR and Water Shutoff of High-viscosity Oil Pools

Novel physicochemical gel-technologies have been developed to improve oil recovery of high-viscosity oil pools. Presented are results of laboratory research and pilot tests. Use of gel-technologies employing inorganic and polymer gels at thermal-steam and cyclic-steam treatments in oil fields of Russia and China increases coverage by steam injection, decreases water cut of well production by 3-45%, increases oil production rate by 11-33% and decreases liquid production rate by 14-25%.
