A method and apparatus for displaying depth of positional data with tubing analysis data obtained by instruments analyzing tubing sections being withdrawn from a well includes an apparatus for communicably linking an encoder or other positional or depth sensors to the tubing analysis data processor. In addition, sensors capable of detected collars holding pieces of tubing section together can transmit signals to the analysis data processor that a collar has been detected and insert collar location information into the analysis data. Furthermore, information based on the length of the individual pieces of tubing or the data from the encoder or other positional sensor can be analyzed or associated with the analysis data and displayed with the analysis data by overlaying a depth component on a display of the analysis data.
