Using a top drive DQ40B-JH a new production oil well of more than 1780 meters depth was drilled in Bashkiria

A new controlled directional production oil well of more than 1780 meters depth was built in Bashkiria. A drilling rig VZBT 2900/175 DEP equipped with the top drive DQ40B-JH was used to build this oil well. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week under service agreement with a drilling company.

The DQ40B-JH is an optimal choice for using as with mobile drilling rigs and with fixed land 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.
