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
