Directional well was drilled in Siberia for DULISMA oil company. The well depth was more  2100 m. Our top drive system DQ50B was used at -52oC.

 Performance of the top drive had the following maximum values:

  • rotation speed 80 rpm./min.; 
  • torque 25 kNm;

The customer was satisfied with the reliability, security and performance of equipment, the quality and the timing of our work.
