Value to client
- Address predominantly Lateral and Axial vibration modes
- Maintains wellbore at nominal gauge
- Reduces damage to FE tools
- Aids bit self centering during bit whirl and reduces bit damage and expensive trips
- Reduces hole spiraling and improves weight transfer to the bit
By stabilizing the BHA negates the need to reduce RPM or Increase WOB as a mitigation technique
