Effectiveness of a new silicone composition for improving water and gas shutoff in horizontal wells of the Kuyumbinskoye field

The article considers the problem of isolation of water and gas inflow in horizontal wells of carbonate fields, especially in the Kuyumbinskoye oil and gas condensate field. Objective. To develop a new silicone composition for sealing in the conditions of fractured reservoirs. Materials and methods. Laboratory and field studies were carried out, including compatibility tests with formation water and oil, as well as strength and filtration tests. Results. The studies showed high chemical compatibility of the formulation with fluids and rapid formation of an isolating mass. In the field, the composition proved its effectiveness when injected into wells with water and gas inflows. Pre- and post-treatment monitoring confirmed flow reduction. Conclusions. The composition enhances insulation durability, lowers operating costs and minimizes environmental impact.
