Abstract
There is a growing number of fields in the world that are at the last stage of development. These fields are characterized by high residual oil saturation and water saturation. In addition, newly discovered fields are characterized by the content of high-viscosity oil. The development of such reservoirs is associated with great difficulties. This paper considers a combined technology that allows to intensify oil production from oil reservoirs. The studies were carried out on a homogeneous reservoir model in the following sequence. First, we carry out the displacement of oil by injecting electrochemically modified water (catholyte). Then we pump in a gas-liquid emulsion slug, which we push through with water or catholyte. The combined action of the emulsion and catholyte leads to an increase in the pressure drop and a change in the filtration rate. As a result, this leads to an increase in the oil recovery factor.
