A new production oil well of more than 3120 meters depth was built in Prirazlomnoe oilfield in Khanty-Mansyisk Autonomous region. A drilling rig Uralmash 2900/250 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 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.
