Downhole Drillpipe Buckling Visualization Accurately Defined WOB Limits
2 PagesCase History A major North Sea operator wanted to use offshore real-time data to verify their drillpipe (DP) buckling simulations for 6 5 /8- in. liner screen and packer setting applications inside 9 5 /8- in. casing. The operator’s buckling calculations indicated that helical buckling begins with weight on bit (WOB) of 24 tons. After completing a liner screen setting operation at 12,470 ft (3800 m) measured depth (MD) and 5,176 ft (1577
