Gazprom Neft and China National Petroleum Corp. will study feasibility of surfactant flooding of Sutorminskoye oil field in Russia’s Yamal-Nenets Autonomous Area as a first step under a new technical partnership.
The companies agreed to develop and adopt advanced techniques for increasing oil recovery, including polymer and surfactant injection.
Gazprom Neft claimed a “successful track record” with those methods, saying they helped boost recovery to 69% in a depleted area of West Salymskoye field in the Yamal-Nenets Autonomous Area.
CNPC said polymer flooding has been effective in Daqing oil field in China.
