The Ultimate Stick-Slip Solution Ulterra's unique TorkBuster tool dramatically reduces bit related torque and stick-slip problems adding significant efficiency to drilling operations.
  • Improved stability, reduced stick-slip
  • Smoother reactive torque in BHA
  • Improves bit life and ROP
  • Extends PDC bit range
  • Enhances directional control
  • Reduces BHA fatigue

Short near bit stabilizer designed specifically to achieve a better quality well bore by reducing hole spiraling and increasing directional control by changing the location of the BHA contact points.
  • Removes bit related Stick-Slip and improves bit stability
  • Allows use of more aggressive/efficient cutting structures
  • Improves bit life and ROP
  • Allows harder formations to be drilled with PDC bits
  • Allows easier control of directional assemblies
  • Reduces fatigue on BHA components
The Inertia tool generates lateral vibration into the drill string to reduce friction. Its ability to add friction-reducing vibration into a drill string can enhance weight transfer to the bit, alleviate torque and drag effects in the string and aid in drilling efficiency.
  • Reduced reactive torques
  • Improved tool-face control
  • Faster ROP
  • Added lateral vibration to drill string enhances weight transfer to bit and drilling efficiency
  • Lower pressure drop allows utilization of multiple tools
  • Zero mud pulse eliminates MWD frequency interference
  • Robust design and all metal construction insures industry leading operating life and high temperature capability
