Abstract:
A system is disclosed for determining the position of a downhole drill pipe relative to a pipe handling device. The system comprises: an imaging means arranged to capture an image of the drill pipe in a region of the pipe for engagement by the device; and a processor operable to analyse said captured image and to determine therefrom the position of the drill pipe relative to said device.
