Rival’s AXEial anti-shock and vibration tool also know as the AXE TOOL™ is designed to absorb and eliminate axial shocks and excitation whereas traditional spring-based shock tools and thrusters redirect vibrations and excitation without removing them from the BHA.

Whether drilling conventionally or with an RSS system, the patented design’s anti-shock elements interrupt axial shock and vibration cycles. In addition, it’s preloaded assembly provides bi-directional dampening with any amount of weight applied.

Function:

  • Tool placed within or directly above the BHA
  • Polyurethane anti-shock elements absorb axial shocks and excitation
  • Pre-loaded for shock and excitation elimination in both directions

Benefits:

  • Reduction in axial vibration, mitigates damages & improves well delivery consistency
  • Tool improves drill bit depth-of-cut consistency, protecting cutting structure to drill faster and farther
  • Compatible with all RSS tools regardless of MWD placement
  • Can be run with air, mist, foam or mud systems
  • Provides a consistent force to the bit by balancing hydraulics against mechanics even in erratic situations
