A new horizontal oil well of more than 2910 meters depth was built in Mityaevskoe oil field in Samara region for Rosneft company by RN-Burenie company. A mobile drilling rig RG ZJ-30 equipped with a top drive DQ40B-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 RN-Burenie company.

The DQ40B-JH is a powerful top drive for mobile and land drilling rigs of 160 - 200t lifting capacity. It allows to build fishbone oil wells of up to 4000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of 420hp power. This allows drilling with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 33 kNm.
