Abstract
The article considers ways to solve the problem of efficiency of formation waterflooding with heavy oil by applying technology of polymer and alkaline (surfactant) flooding on the example of the layer PK1-3 of the Vostochno-Messoyakhskoye field. At high viscosity difference between displaced and displacing agents, the displacement front is unstable and formed breakthroughs water. The situation is worsened by the fact that the geology of the reservoir is extremely heterogeneous in properties, which intensifies the nonuniformity of the displacement front of oil by water.
