A fund of production oil-wells in Samotlorskoe oil-field in Khanty-Mansiysk Autonomous region has been replenished by a new oil-well of more than 3200 meters depth.  A mobile drilling rig ZJ-40CZ equipped  with a top drive DQ40B-JH was used by RN-Burenie 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 RN-Burenie company.

The DQ40B-JH is an optimal top drive model for using as a part of the 200t mobile drilling rigs for sidetracking and oil-wells drilling of up to 4000 meters depth including fishbone oil-wells. 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.
