700HP Rack and Pinion

Drilling Rig | EMAS Energy

Drilling Rig

  • Capability of lifting 250,000 pounds as a conventional workover rig but also acts as a conventional 125,000-pound snubbing unit  
  • Considered as a self-contained unit capable of all underbalanced drilling, milling, workover and snubbing operations  
  • Featured with a 24 metre mast, the 250K UB Rig allows for a number of BOP configurations to be added (while maintaining standard drilling and tripping capabilities)   
  • The 250K UB Rigs have a smaller footprint than conventional service rigs allowing operations in tighter locations and reducing land disturbance
