A new oil well of more than 2400 meters depth was built in Em-Egovskoye oilfield in Khanty-Mansiysk Autonomus Region. A drilling rig ZJ50DBS equipped  with a top drive DQ50B-JH was used by RN-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 RN-Burenie company.

The DQ50B-JH as well as DQ50BQ-JH is the most popular top drive model among drilling companies.  It allows to build fishbone 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 500hp power. This allows drilling with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 40 kNm.
