Abstract
Casing wear is the phenomenon caused by the tribological contact of the drill string tool joint with casing. This contact causes a decrease in the thickness of the inner casing wall, weakening the structural resistance of the oil well, which can cause production stoppages and integrity failures. The API 7CW standard proposes a methodology for full-scale casing wear tests that requires considerable physical structure and material consumption. In addition to the 7CW standard, the technical literature presents mathematical models for predicting casing wear from field data. In this work we developed a methodology for small-scale casing wear test and wear mechanism evaluation. For this purpose, API 7CW, ASTM B611 -13 and NBR 13818-97 standards were used as reference. In the end, the small-scale test could be validated by comparing the wear behavior in the small-scale test with those found in the technical literature. In addition, the wear mechanisms of casing sample were analyzed Thus, the results obtained in the smallscale test may be used in the future for comparison with API 7CW tests. Moreover, this work enables the study of different hardbanding materials in a simpler way, in order to apply them in the most efficient way.
