A fund of ROSNEFT production oil wells in Khanty-Mansiysk Autonomus region has been replenished by a new oil well of more than 4310 meters depth.  A  drilling rig Uralmash 5000/320 EK-BMCH equipped  with a top drive DQ70BSQ-JH was used by RN-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 RN-Burenie drilling company.

The DQ70BSQ-JH is one of the high performance models of top drives and provides drilling of the wells up to 7000 meters deep (with a 114 mm drill pipe). The top drive is equipped with two asynchronous frequency controlled electric motors with a power of 500 hp each. This allows to perform drilling with a smooth shaft speed changes in the range from 0 to 230 rpm and with a working torque of up to 65 kNm.
