Samotlorneftegaz, one of Rosneft’s largest production assets, has carried out 40-stage hydraulic fracturing (HF) for the first time. The operation at the Samotlor field on a horizontal well was completed in 24 hours, which is a record in the industry. Its productivity coefficient exceeds the average indicators of neighboring wells by up to four times.
The wellbore depth was 3,469 meters, the horizontal section length was about 1,200 meters. During the operation, 2,100 m3 of reservoir pressure maintenance system water were pumped in, and new generation domestic couplings were used.
The unique operation was carried out by specialists from Samotlorneftegaz and the corporate service company RN-GRP, which carries out all hydraulic fracturing work at the Samotlor field. Currently, the share of wells with multi-stage hydraulic fracturing in the total volume of drilling of the enterprise exceeds 86%.
Over the course of several years, Samotlorneftegaz specialists have adapted and selected the most effective methods for conducting multi-stage hydraulic fracturing to the conditions of the Samotlor field. The company’s specialists have conducted pilot industrial work on 20-stage multi-stage hydraulic fracturing. The positive results of this work have allowed us to quickly reach a new milestone, increasing the number of stages to 29, and now to 40 stages.
Systematic work to improve production efficiency is one of the key elements of Rosneft’s strategy. The company carries out large-scale work aimed at introducing advanced technologies and reducing operating costs. Developments of corporate scientific institutes and equipment from domestic manufacturing plants are actively implemented at production sites.
