Abstract

Casing wear is one of the primary factors that impact the well integrity in oil and gas operations. Therefore, this paper aims to investigate and understand the effect of the drilling parameters such as drill string rotational speed, rate of penetration (sliding speed), and side loads on the casing wear volume and factor. An experimental study with actual drill pipe joint and casing designed to simulate the drilling operations. Three different steel grades P110, L80, and sm2535-110 were tested under oil-based lubrication at two different loads (1000 N and 1400 N) and a constant rotational speed (115 rpm) and sliding speed of (2.5 mm/s). Casing wear tracks were analyzed by an optical profilometer to determine the track depth and area. A specially designed in-situ depth measuring system was validated by a precise optical profilometer and used to estimate the wear volume. The results show the higher the side load the higher the wear factor. Furthermore, under a side load of 1400N and a rotational speed of 115 rpm, SM2535-100 steel had the highest wear factor of 1.521 (10-6 MPa-1) and P110 steel had the lowest 1.043 (10-6 MPa-1). The combination of rotation and sliding motion has resulted in a significant increase of casing wear volume and factor for all three materials.
