A fund of GAZPROM-Neft production oil wells in Yamal-Nenetsk Autonomous region has been replenished by a new oil well of more than 4510 meters depth.  A drilling rig 3900/225 EK equipped  with a top drive DQ50BQ-JH was used by NaftaGaz-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 NaftaGaz-Burenie drilling company.

The DQ50BQ-JH as well as the DQ50B-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 600hp 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 48 kNm.
