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 the14” casing while drilling the12¼”,

8½”and6½” hole sections. NRPs were placed in the build of the well where maximum side forces were expected. After reaching the wells’ TD a Multi-finger Caliper (MFC) was ran to measure the % of wall worn of the casing. The maximum simulated casing wear without the use of NRPs yielded between 20 to 55%. Whereas the maximum actual wear only reached 7 to15% with the use of NRPs. The use of NRPs resulted in over 70% decrease in casing wear.
