A new production oil well of more than 2970 meters depth was built in Sredne-Balykskoe oilfield in Khanty-Mansiysk Autonomous region. A drilling rig Uralmash 4000/250 EK-BM equipped  with a top drive DQ50BQ-JH was used by Rosneft-Burenie professionals to build this oil well . A non-stop top drive performance was provided by SLC service engineers working 24 hours a day 7 days a week with a drilling crew under service agreement with Rosneft-Burenie company.

The DQ50BQ-JH as well as the DQ50B-JH is the most popular top drive model among drilling companies.  It allows to build fishbone oil wells of up to 5000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of  600hp power. This allows to drill with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 48 kNm.
