The article presents the experience of water flow limitation application in wells with multistage hydraulic fracturing in carbonate deposits of the Moscovian Stage of the unique Arlanskoe field. The methods and technologies used to reduce water flow, which is an important task for increasing the efficienсу of hydrocarbon fields development are described in this work. The paper analyzes the geological and technical characteristics of the field and the dynamics of horizontal well performance indicators, and reviews the experience of application of water shut-off technologies in horizontal wells with fractures after multistage hydraulic fracturing. The authors presented a matrix for selection of water shut-off technologies in horizontal production wells. On the basis of the performed works three groups of compositions were singled out. According to the results of the analysis, the best technological effect was obtained using integrated technology including injection of cross-linked polyacrylamide, polymer-silicate composition and lightweight plugging composition. The obtained results demonstrate the positive impact of the proposed measures on the optimal production of reserves and reduction of negative consequences associated with water production. The work may be of interest to specialists in oil and gas geology and field development, and is aimed at optimizing the exploitation of carbonate reservoirs.
