Evaluation of oil displacement by water or gas in oil fields

Article is devoted to research on the displacement of oil by water or gas in oil fields. The purpose of this work is to increase the efficiency of impact on the field. A laboratory facility has been created to study the release of oil from the core by water and gas. The cores used contain brine as well as oil Experiments were carried out to determine the comparative effect of changing the properties of the fluids used. The displacement was carried out at a pressure close to atmospheric.
