Analysis of the effectiveness of the application of technologies of physicochemical methods for increasing oil recovery in the fields of Surgutneftegas PJSC

At many operational facilities, there has been an outstripping increase in water cut of products, due to both the geological characteristics of the reservoir and the technological mode of operation. In order to stabilize the growth of waterlogging in the Khanty-Mansi Autonomous Okrug-Yugra fields, flow diverting technologies and leveling the injectivity profile of injection wells have become widespread. In analyzing the effectiveness and composition of specific technology modifications, the experience of Surgutneftegas PJSC was used. The fields of this oil company account for about 60% of the total volume of geological and technical measures based on flow diverting technologies in the district.
