A fund of ROSNEFT production oil wells in Khanty-Mansyisk Autonomous region has been replenished by a new controlled directional oil well of more than 3380 meters depth.  A mobile drilling rig ZJ-40CZ equipped with a top drive DQ40B-JH was used by ROSNEFT-Burenie drilling crew for drilling 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 drilling crew under service agreement with ROSNEFT-Burenie drilling company.

DQ40B-JH is an optimal choice for using with mobile drilling rigs. It allows to build fishbone oil wells of up to 4000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of 420hp 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 33 kNm.
