A new production oil well of more than 4720 meters depth was built in Sredne-Balykskoe oil field in Khanty- Mansiysk Autonomous region

A new controlled directionsl production oil-well of more than 4720 meters depth was built by RN-Burenie drilling company at Sredne-Balykskoe oil-field in Khanty-Mansiysk Autonomous region for Rosneft company.  A drilling rig ZJ50DBS equipped with a top drive DQ50BQIII-JH was used by RN-Burenie team to build this oil well. A top drive 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 DQ50BQIII-JH as well as the DQ50BQ-JH and the DQ50B-JH is the most popular top drive model among drilling companies.  It allows to build fishbone wells of up to 5000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of 1089hp power. This allows drilling with a smooth shaft speed changes in the range from 0 to 220 rpm and with a working torque of up to 69 kNm.
