Abstract
A wellbore evaluation system evaluates mechanical wear and corrosion to components of a well system including a production tubing string positionable in a well and a sucker rod string movable within the production tubing string. A deviation sensor determines a deviation profile of the production tubing string in the well, and a rod sensor senses and measures wear and corrosion to the sucker rod string as it is removed from the well to determine a rod profile. A data acquisition computer is in communication with the sensors for computing and comparing the deviation profile and the rod profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.
