Evaluation of Water Breakthrough Mechanisms and Selection of Water Shut-off Techniques for Carbonate Formation Wells

Abstract
The current state of late stage oil field development is characterized by increasing water cut, the need to extract and transport large volumes of produced water, which significantly reduces the profitability of operating such fields. In this context, water shutoff operations hold a unique position among measures aimed at optimizing oil production operating costs. The paper presents the results of testing and implementation of a comprehensive waterproofing technology using sedimentary gel-forming compounds at the TashlyKulskoye field (the Republic of Bashkortostan, Russian Federation). The work was carried out in difficult geological conditions of the C1ksl formation of the Tournaisian stage, represented by monolithic carbonate reservoirs. The measures carried out have shown high efficiency about 95%.
