A fund of Gazpromneft production oil wells in Tomsk region has been replenished by a new oil well of more than 3400 meters depth

A fund of Gazpromneft production oil wells in Tomsk region has been replenished by a new controlled directional oil well of more than 3400 meters depth.  A drilling rig Uralmash 3000 EUK-1M equipped with a top drive DQ50B-JH was used by BSK “Grand” drilling crew for drilling this oil well. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week under service agreement with BSK “Grand” drilling company.

The DQ50B-JH as well as the DQ50BQ-JH and the DQ50BQIII-JH is the most popular SLC-JH 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 500hp 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 40 kNm.
