Laboratory study of the oil displacing ability of a chemical acid oil-displacing composition

The paper presents the results of laboratory experiments to study the filtration characteristics of models of a heterogeneous reservoir of a Permian-carbon deposit in the Usinsk mine and the oil-displacing ability of a chemical acid oil displacing composition (AODC). The experiments were carried out on a setup for studying the filtration characteristics of heterogeneous reservoir models. The study found that the use of AODC will lead to a significant increase in the coefficient of oil-displacement.
