At an oilfield in Yamal-Nenetsk Autonomous region was increased a production well flow rate

The production well was reconstructed at the oil field in Yamal-Nenetsk Autonomous region using sidetracking  technology, as a result of which its flow rate was increased. The work was carried out using a mobile drilling rig MBU-160 equipped with a DQ20B-JH top drive.  A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week in according with service agreement with a drilling company.

The DQ20B-JH as well as the DQ30B-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.
