ROSPAN International expands its resource base at the Vostochno-Urengoyskoye gas field in the Yamal-Nenetsk region

ROSPAN International has been increasing its gas production capacity in the Yamal-Nenetsk Autonomous region. Another production gas well has been built at the Vostochno-Urengoyskoye gas field. Its depth was more than 5100 meters, the length of the horizontal section was more than 1300 meters.

A drilling rig BU-5000/320 EK-BMCH equipped with a top drive DQ70BS-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 RN-Burenie drilling company.

The DQ70BS-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 420 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.
