Using a top drive DQ40B-JH a new oil well of more than 1840m depth was drilled in Yamal-Nenetsk Autonomous Region

A new controlled directional production oil well of more than 1840 meters depth was built in Novoportovskoe oil and gas field in Yamal-Nenetsk Autonomous region. A mobile drilling rig ZJ-40T equipped with a top drive DQ40B-JH was used by IGS-NEU professionals to build this gas well. A top drive aftermarket field service support was provided by SLC service engineers working 24 hours 7 days a week with a drilling crew under service agreement with IGS-NEU company.

The DQ40B-JH is an optimal choice for using with heavy-class 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.
