Title: CASING WEAR ESTIMATION
Abstract:
Casing wear estimation. At least some of the illustrative embodiments are methods including: calculating a value indicative of static casing wear of the drilling operation, the static casing wear caused by interaction of a drill string against an inside diameter of a casing; calculating a value indicative of impact casing wear of the drilling operation, the impact casing wear caused by interaction of the drill string against the inside diameter of a casing; and combining the value indicative of static casing wear and the value indicative of impact casing wear to determine the value indicative of aggregate casing wear.
