Failure to accurately estimate casing wear could lead to collapse, burst, lost circulation, and several other complexities. The most important parameters that affect wear and result in different wear mechanisms are the sizes of the casing, the grade of the pipe, drill-pipe size, hard banding material, base type of fluid, side loads, penetration rate, and pipe rotation speed. The present work is focused on the effects of the combination of rotation and translation on the wear mechanisms of three different casing materials P110, L80, and SM2535 under an oil-based lubricant. The experimental work considers two side loads 1000N and 1400N, a rotational speed of 115rpm, and a rate of penetration (ROP) of 2.5mm/s. The worn casing surfaces are analyzed by Digital Microscopy and Scanning Electron Microscope (SEM). The results showed that, for all tree materials, the dominant wear mechanism under rotation only was circumferential abrasion with solid particles from the lubricant. While the combination of rotation with ROP caused circumferential and axial abrasive wear with the presence of deep grooves and delamination. It must be mentioned that more damage was observed for casing pipes made of SM2535. © 2023 The Authors. Published by ELSEVIER B.V.
