WWT NRPs Protectors Provide Casing Protection at Sidetrack

A Gulf of Mexico well required 14’’ casing protection at an 8°/100ft sidetrack. WWT installed 378 HD-SS3-658-slim model NRPs at 2 per joint due to excessive side force. The slim version was necessary for RCD compatibility, stripping NRPs out of hole with 350 psi backpressure. Due to excessive tar, a bypass section was also drilled and TD of 29,850 ft was successfully reached. Approximately 50 NRPs went into the open hole salt formation to protect the sidetrack point throughout both bit runs.

PROTECTED CASING ON A DEEPWATER WELL WITH MPD

A deepwater offshore well had a shallow dogleg and build that resulted in needing casing protection. 
WWT installed 576 SS3-658-slim model NRPs. The slim version was necessary for RCD compatibility. 
MPD was used with 330 psi backpressure. 

WWT NRPs Reduce Drilling Torque to Stay Below Limit

WWT NRPs were deployed to reduce torque and prevent heat checking while drilling an S-shaped well in the Gulf of Mexico.

WWT NRPs Replace Steel Protectors in GoM Well

After experiencing slipping and detachment issues with a competitor’s clamp-on steel protectors in a previous section, WWT’s Non-Rotating Protectors (NRPs) were deployed for the 12-1/4” section in conjunction with the competitor’s sub-type steel protectors as a solution to mitigate casing wear and reduce torque

WWT NRPS SMOOTH & REDUCE DRAG THROUGH BUCKLED CASING

A deepwater offshore well had a highly deviated and buckled production casing throughout most of the 
wellbore. The contact from pipe to casing resulted in high drag and made completion operations difficult 
due to high set down weight volatility. WWT installed 594 SS3 model NRPs.
