Conclusion One of the primary factors that affect the integrity of the well in oil and gas operations is casing wear. Therefore, an experimental study was conducted on three types of materials under different drilling parameters. • The wear depth was measured using calibrated in-situ displacement indicator. • It was found that the wear volume increases as the side load increase for P110, L80, and sm2535-110 for both rotational motions only and combined rotational and sliding motion due to the increase in contact between the casing and tool joint. • When the experiment was conducted under a load of 1400N and rotational speed of 115 rpm, the wear factor of P110, L80, and sm2545-110 was found to be 4.86 (10 -9 MPa -1 ), 5.95 (10 -9 MPa -1 ), and 369.52 (10 -9 MPa -1 ) respectively, while under the same load and rotational motion and sliding motion of 2.5 mm/s, the wear factor of the three materials found to be 1,042.93 (10 -9 MPa -1 ), 1,349.16 (10 -9 MPa -1 ), and 1,520.84 (10 -9 MPa -1 ) respectively. • It was found the effect of the combined motions for P110 and L80 is significant where the wear factor increased by a factor of almost 200, while it has a slight effect for sm2535-110 where the wear factor increased by a factor of almost 4.1. • In general, the combined motion results in a higher wear factor for the three types of materials. The possible explanation is that the sliding motion leads to friction contact in both axial and normal directions to the tool joint, hence, the worn volume will increase.
