Features of the technology of interval fracturing in horizontal wells

The paper assesses the effectiveness of multi-stage hydraulic fracturing at the wells. The wells used a system of circulating valves (discontinuous ports), the passage in the valve was opened by a drop ball, and a interval multi-stage hydraulic fracturing was subsequently performed through them. In the process of well construction, non-cemented liners with “Rockseal” inflatable packers were lowered into productive formations.
