Abstract

This study includes an environmental and social baseline of the oil sector in the region, an analysis of the potential key environmental and social issues, with which an assessment of impacts was made. The authors studied the key geological and physical parameters of productive formations. The authors found out that one of the main problems of the development system of the considered oil field is associated with the AV1-3 formation, which is characterized by worsened energy state and low recovery factor. The authors designed the reorganization of the reservoir pressure maintenance (RPM) system at the pilot site of the facility AV1-3 as a solution to the problem. This decision will allow increasing the sweep efficiency of the reservoir by waterflooding, and as a result – it will increase the oil recovery factor and remaining recoverable reserves.
