Application of polymer flooding to increase oil recovery

Abstract This article examines the problem of non-uniform oil displacement during the development of multi-layer fields and proposes a promising approach to solve it – polymer flooding. The article outlines the basic principles of polymer flooding, including dissolving polymers in water to increase viscosity and reduce water mobility. Various types of polymers used in this technology and their unique characteristics are considered. The advantages of polymer flooding are highlighted, such as increasing reservoir coverage and increasing oil production efficiency. The illustrations presented in the article compare oil displacement using polymer flooding and traditional methods. In conclusion, a comparative description of various types of polymers in terms of composition and main application parameters is given and the importance of this technology in the context of ensuring sustainable and efficient oil production in multi-layer fields is substantiated.
