NOVATEK expands its resource base on Kharbeyskoye gas field in the Yamal-Nenetsk Autinomous region

NAVATEK has been increasing its gas production capacity in the Yamal-Nenetsk Autonomous region. Another production gas well has been built on Kharbeyskoye gas field. Its depth was more than 4990 meters, the length of the horizontal section was more than 1520 meters.

A drilling rig BU-5000/320 EK-BMCH equipped with a top drive DQ70BSQ-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 SSK drilling company.

The DQ70BSQ-JH is one of the high performance models of top drives and 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 500 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 65 kNm.
