As more directional and sidetrack wells are drilled, issues relating to casing, liner, and tubing wear are becoming increasingly critical. Accurate wear prediction is important for well integrity and optimized well designs. As a result, a better understanding of casing wear and the theory behind its estimation is desired.

This webinar will showcase the fundamentals of casing wear, followed by the implications of using it and factors that may affect it. In addition, the difference in using soft-string and stiff-string models to calculate casing wear will be examined. The accuracy of traditional casing wear estimation can be improved by looking at newer algorithms and complex engineering calculations involved in these newer models.

This webinar will also highlight wear factor and the enigma that it is. By using historical data, we are better able to predict and identify the hidden truth about wear factor. The end of the webinar will showcase a realistic scenario of the simulation and validation process to optimize well design.
