A new production oil well of more than 3400 meters depth was built in Samotlorskoe oil field in Khanty-Mansyisk Autonomous region

A new horizontal production oil-well of more than 3400 meters depth was built by RN-Burenie drilling company in Samotlorskoe oil-field in Khanty-Mansyisk Autonomous region for Rosneft company. It took about 26 days to drill it. A mobile drilling rig ZJ-40 equipped with a top drive DQ40B-JH was used for this purpose. 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 RN-Burenie company.

The 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.
