A new production gas well of more than 5130 meters depth was built for NOVATEK company

A new production horizontal gas well of more than 5130 meters depth was built on Kharampurskoye gas field in Yamal-Nenetsk Autonomous region for NOVATEK company by SSK. 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.

The DQ70BSQ-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 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.
