Rival’s Stick-Slip & Torsional Oscillation Reduction and Mitigation Tool aka the STORM TOOL™ is designed to mitigate drilling dysfunction in rotary steerable system (RSS) applications.
While drilling with a motor-assisted RSS, the BHA becomes self-excited as the drill bit cutting structure engages with the formation, and the motor responds to torque demands creating drilling dysfunction. Unmitigated, these cycles reduce the predictability of drilling operations and increases RSS costs.
The STORM Tool decouples the motor from the RSS & drill bit axially while its internal mechanism absorbs damaging torque oscillations within the BHA.
By interrupting torque oscillation cycles, the frequency and severity of shock & vibration events are reduced.
The STORM Tool is WOB independent, and its fixed-length maintains drill bit depth-of-cut, protecting the cutting structure and improving bit life and interval ROP.
Function:
- Tool placed directly below motor in RSS BHA
- Torque oscillations converted into axial movement of WOB independent mass
- No axial displacement of outer housing
- Dampening effect to absorb mechanical energy (shock absorption)
- Minimizes drilling dysfunction by axially decoupling the RSS from the drilling motor
Benefits:
- Reduction in shock & vibration mitigates damages & improves well delivery consistency
- Tool maintains bit depth-of-cut protecting cutting structure to drill faster & farther
- Compatible with all RSS tools regardless of MWD placement

*Back-reaming should be avoided. If back-reaming is unavoidable it should only be performed at less than 40 rpm, and caution should be taken when changing axial directions. If dogleg is over 16°/100 ft, then back-reaming rpm should be held to a maximum of 10 rpm.
