A new controlled directional oil well of more than 4050 meters depth was built in Tarasovskoe oilfield in Yamal-Nenetsk Autonomous region. A drilling rig Uralmash 3900/225 EUK equipped with a top drive DQ50B-JH was used by NaftaGaz-Burenie professionals to build this oil well. A top drive aftermarket 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.
