Slavneft expands its resource base at the Kuyumbinskoye oil and gas condensate field in the Krasnoyarsk region

Slavneft has been increasing its oil production capacity in the Krasnoyarsk region. Another production oil well has been built at the Kuyumbinskoye oil and gas condensate field. Its depth was more than 3960 meters, the length of the horizontal section was more than 950 meters.

A drilling rig BU-225E equipped with a top drive DQ70BS-JH was used for this purpose. 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 BNGRE 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.
