WWT: Non-Rotating Protector (NRP)

WWT Non-Rotating Protectors (NRPs) are the industry’s leading mechanical torque and friction reduction tool, designed to improve drilling efficiency, protect casing and risers, and extend drill string life. For more than 30 years, WWT International has partnered with operators worldwide to overcome complex downhole challenges  including excessive torque, drag, casing wear, riser wear, heat checking, drill pipe buckling, and energy loss caused by wellbore friction.

Often referred to as drill pipe rubbers, WWT’s NRPs combine extensive engineering with field-proven reliability, offering operators a fully supported, performance-optimized  solution for all well types.

Key Benefits:

  • Reduce torque and drag — improve drilling efficiency and energy transfer to the bit
  • Prevent casing and riser wear — isolate tool joints to eliminate direct metal-to-metal contact
  • Mitigate heat checking and pipe damage — extend the life of tubulars and drilling components
  • Lightweight clamp-on design — easy to install, adds negligible weight, and maintains derrick racking capacity
  • Fast installation — each NRP can be installed in just over one minute, online or offline
  • Compatible with Managed Pressure Drilling (MPD) and Rotating Control Devices (RCDs)
  •  Robust, versatile design — ideal for cased, open hole, and deepwater riser applications

Engineering Support and Well Modeling Expertise

A complementary well analysis with torque & drag modeling backs every WWT NRP deployment. Our engineers evaluate your wellbore conditions and provide a custom placement recommendation to identify where NRPs will deliver the greatest benefit.  This modeling compares torque and drag with and without NRPs, ensuring optimal protection and performance.

WWT can also provide casing wear modeling and ECD impact analysis to help operators make fully informed decisions.
