Casing Wear Mitigation

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 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 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 Reduce Casing Wear by Over 70%

WWT NRPs were deployed to prevent casing wear in eight directional wells for offshore Mexico. The goal was to protect the 14” casing while drilling the 12 ¼”, 8 ½” and 6 ½” hole sections.
