Developing the efficiency of low-productivity oil deposits via internal flooding

Abstract The article studies geological and technological parameters’ impact on degree and nature of production wells. The wells influence the water injection into wells in the carbonate reservoirs of the Tournaisian stage of the Birsk saddle. The study presents an algorithm with substantiating technological solutions to increase the efficiency of developing low-productive deposits via internal flooding. It also considers the development of facilities for hard-to-recover reserves with high production costs and low profitability. This is made in order to use the resource base of the Volga-Ural oil and gas provinces more efficiently.
