A new controlled directional oil well of more than 3470 meters depth was built in Danenbergovskoe oil field in Tomsk region

A new controlled directional oil well of more than 3470 meters depth was built in Danenbergovskoe oil field in Tomsk region for TOMSKNEFT company. A drilling rig Uralmash 3000 EUK-1M equipped  with a top drive DQ40BQ-JH  was used for this purpose. A non-stop top drive performance was provided by SLC service engineers working 24 hours a day 7 days a week with a drilling crew under service agreement with Tomskburneftegas  company.

The DQ40BQ-JH 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  500hp 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 40 kNm.
