Coiled tubing - Wikipedia

A coiled tubing unit (CTU) is a self-contained multi-use machine that can do almost anything that a conventional service rig does - with the exception of tripping jointed pipe. There are generally two types in shallow service - Arch and Picker. One uses a vertical elevator with a horsehead on top, and an injector hanging by winch line off it.
