In Yamal-Nenetsk Autonomous region increased a production well flow rate

The production well was reconstructed on the Rosneft oil field in the Yamal-Nenetsk Autonomous region using sidetracking  technology, as a result of which its flow rate was increased. The work was carried out using mobile drilling rig MBU-160 equipped with a DQ30B-JH top drive.  A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week under service agreement with a drilling crew.

The DQ30B-JH as well as the DQ20B-JH is specially designed for use with light and middle-class mobile drilling rigs. It allows to drill oil and gas wells up to 2000m deep (using drill pipes with a diameter of 114mm) in the shortest possible time.

The top drive is equipped with an asynchronous frequency controlled electric motor of 335 hp power, which allows drilling with a continuously adjustable shaft speed in the range from 0 to 180 180 rpm and with a working torque of up to 26 kNm.
