1. A method of locating apparatus mounted external to a tubular, the method comprising:
deploying an imaging device having an acoustic sensor into the tubular;
creating acoustic images using the acoustic sensor from acoustic reflections from the tubular and portions of the apparatus contacting the tubular; and
processing the acoustic images with a computer model to determine a location of the apparatus; and
outputting the location of the apparatus.
