Abstract
The subject matter of this specification is directed to a method that includes providing an outer tubular member having a bore with an inner surface, applying a lubricant layer to at least a portion of the inner surface of the outer tubular member, and positioning the outer tubular member in at least a portion of the wellbore. During the drilling process, mechanical wear between the outer and inner members can be measured by an indicator to determine if the measured indicator exceeds a predetermined threshold level.
