WWT Non-Rotating Protectors™

WWT Non-Rotating Protectors™ (NRP) are the world’s most widely used mechanical drill-string friction reducer applicable in various well types to optimize energy delivery to bit by significantly reducing torque, drag, casing and riser wear, heat checking and buckling.

Benefits and Features:

  • Stand-off between the drill-pipe and wellbore to prevent casing wear, riser wear, and heat-checking – casing integrity
  • Sliding and rotating friction factor reduction - torque and drag reduction
  • Robust but drillable design proven in the world’s harshest and most challenging wells – proven product
  • Comprehensive torque and drag analysis provided with all potential applications – T&D expertise
  • Safe and fast installation offline or online without adding connections - safety
  • Compatible with oil-based, synthetic based, and water-based mud systems - compatibility
  • Cased and open-hole capabilities – longer bit runs
  • Placement flexibility for BOP space-out - safety
  • Secure installation preventing slippage in high side-force and MPD operations - reliable
  • On/off-site technical support and direction - experience
  • 30 years of knowledge and experience focused on continual improvement in product design and field operations – customer driven

NRP Assembly

WWT Non-Rotating Protectors™ are installed on the drillpipe and create a standoff, effectively isolating the drillstring while preventing damage to critical contact areas of the casing and riser. The NRP assembly consists of a low friction advanced polymer sleeve and two aluminum collar clamps that hold the assembly in place to optimize drilling performance.
