Abstract
A method and apparatus for inspecting and tallying pipe in a well completion system. In one embodiment, at least one sensor determines the length of a pipe and/or at least one thread protector sensor determines whether the thread protectors are removed from both ends of the pipe. The sensors may be located in a mast assembly, a pipe arm, a walkway adjacent said pipe arm used to urge pipe towards the pipe arm, or various other places as desired. A moveable control van with a control system receives signals from the sensors. The control van comprises a system which also keeps a tally of the total amount of pipe currently in the wellbore. In one embodiment, memory chips may be used on the pipe to store a history of the pipe. The sensors then communicate this information back to the control system.
