Casing wear due to pipe body and tool-joint of Range 2 and Range 3 DP is compared using a stiff-string torque & drag & buckling model coupled to a 3D<br>meshed casing wear calculation. Results are compared for multiple well profiles, either smooth or tortuous, in addition to differing pipe-body and tool-joint<br>wear factors.<br>The driving force behind the study was to investigate if the benefits Range 3 DP over Range 2 DP, such as reducing the ECD during drilling as well<br>increasing the lifespan of rotating BOPs, outweigh the potential casing wear. To accurately determine casing wear, all rotating ope
