An apparatus and automated control of the apparatus for use in coiled pipe operations is provided. The apparatus includes a mobile rig or trailer that carries a tower having attached thereto a reef of coiled tubing and a standard coiled tubing injector. The tower is positionable to support the reel of coiled tubing and the injector at a desired elevation above a wellhead. The reel of coiled tubing is supported upon a movable reel cart which is actively positioned by an automated control system to position the reel of coiled tube and ultimately the coiled tubing as it drawn from and drawn upon the reel during operation. The control system monitors the position of the coiled tube as it is passed through the injector and positions the reel cart to minimize the number of bends the coiled tubing is subjected to during one complete iteration of running in and withdrawal.
