A fund of Gazprom-neft production oil wells in Yamal-Nenetsk Autonomous region has been replenished by a new well

A fund of Gazprom-neft production oil wells in Yamal-Nenetsk Autonomous region has been replenished by a new well.  A drilling rig Uralmash 3900/225 EK equipped with SLC-JH top drive DQ50BQ-JH was used for construction this oil well. Total penetration during the well drilling amounted to 4600 meters.  

A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week.

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.
