A new production oil well of more than 4220 meters depth was built on Archinskoe oil field in Tomsk region

A new controlled directional oil well of more than 4220 meters depth was built by Naftagaz-Burenie drilling company on Archinskoe oil field in Tomsk region for Gazpromneft. A drilling rig Uralmash 3000 EUK-1M equipped with a top drive DQ50BQ-JH was used for this purpose. 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 Naftagaz-Burenie company.

The DQ50BQ-JH as well as the DQ50B-JH and the DQ50BQIII-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.
