Supplementary evaluation of the efficiency of water shutoff in production wells

Authors: Yu.V. Zemtsov, A.E. Lytkin (TNNC LLC, RF, Tyumen)

Key words: water shutoff in production wells, well interference, displacement characteristics, enhanced oil recovery

The article explores the efficiency of water shutoff operations in oil production wells from the viewpoint of its impact on oil recovery. Displacement characteristics are proposed as a tool for evaluat9ing the efficiency of such operations. It is demonstrated that at the late development stages water shutoff operations should be performed and utilized as a means of controlling field development and as an enhanced oil recovery technique.
