A fund of GAZPROM-Neft production oil wells in Khanty-Mansiysk Autonomous Region has been replenished by a new oil well of more than 4190 meters depth.

A fund of GAZPROM-Neft production oil wells in Khanty-Mansiysk Autonomous region has been replenished by a new oil well of more than 4190 meters depth.  A drilling rig 3000 EUK-1M equipped  with a top drive DQ40B-JH was used by NaftaGas-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 NaftaGas-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.
