ABSTRACT:
A system for measuring a true vertical depth of a downhole tool is provided. The system includes: a first optical clock located at a first depth and having a first frequency; a second optical clock disposable at a downhole location and having a second frequency at the downhole location; and a processor for receiving the first frequency and the second frequency, and calculating a true vertical depth of the second optical clock based on a difference between the first frequency and the second frequency. A system and computer program product for measuring a true vertical depth of a downhole tool are also provided.
