Coiled tubing (CT) rigs have played a key role in lowering cost in shallow plays. These drilling rigs offer advantages over conventional rigs when mobility, safety, environmentally friendly footprint, and drilling time are needed. Advanced Drilling Technologies (ADT) CT rigs are limited to 5,000 ft whose design provides maneuverability and speed during rigup or rigdown, a process that can be ...

The rig is available in four completely wheeled loads with the exception of Rig 168 that carries five loads to accommodate a larger mud pump with greater capacity.
