The majority of Tatarstan oil fields are currently at the late stage of development, with large amounts of water injected and produced. High rate of reserve recovery from heterogeneous reservoirs results in non-uniform drainage leading to sharp increase of hard-to-recover reserve share. The main oil recovery method in Tatneft Company is water flooding. Enhanced oil recovery can be provided through optimized flood patterns and application of various repressuring agents, including injection of systems with various viscosities (based on polymer thickeners) depending on terrigenous reservoir permeability. The authors suggest a conformance control solution for terrigenous reservoirs with different permeability zones through the application of polymer systems with various viscosities as oil displacing agents (a case study from the Novo-Suksinskoye field).
