Abstract
Methods and systems for evaluating integrity of a tubular located within a wellbore are provided. The method includes measuring an operation parameter of the wellbore, measuring a feature of the tubular two or more times to produce an integrity log each time the feature is measured, and determining a tubular integrity analysis for the tubular by using the integrity logs and the operation parameter. The tubular integrity analysis contains parameter limitations for the tubular. The method also includes determining if tubular integrity is within or outside the parameter limitations. If the tubular integrity is within the parameter limitations, then determine a duration of integrity for the tubular. If the tubular integrity is outside of the parameter limitations, then determine a location on the tubular for loss of tubular integrity.
