A new horizontal oil well of more than 3900 meters depth was built in Yuzhno-Priobskoe oil field in Khanty-Mansyisk Autonomous region

A new production oil well with horizontal design of more than 3900 meters depth was built by NaftaGaz-Burenie in Yuzhno-Priobskoe oil field in Khanty-Mansyisk Autonomous region for GAZPROM-Neft company. A cluster drilling rig Uralmash equipped  with a top drive DQ50BQ-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 NaftaGaz-Burenie company.

The DQ50BQ-JH as well as 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 600hp power. This allows drilling with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 48 kNm.
