A new production oil well of more than 4220 meters depth was built on Tagrinskoye oil field in Khanty- Mansiysk Autonomous region

A new horizontal production oil-well of more than 4220 meters depth was built by SSK drilling company on Tagrinskoye oil-field in Khanty-Mansiysk Autonomous region for Russneft company.  A drilling rig Uralmash 3000 EUK-1M equipped with a top drive DQ70BS-JH was used by SSK professionals to build this oil well. 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 SSK company.

The DQ70BS-JH is one of the high performance models of top drives which provides drilling of the wells up to 7000 meters deep (with a 114 mm drill pipe). The top drive is equipped with two asynchronous frequency controlled electric motors with a power of 422 hp each. This allows to perform drilling with a smooth shaft speed changes in the range from 0 to 220 rpm and with a working torque of up to 55 kNm.
