Abstract: In coiled tubing operations, a mast system is provided which allows for performing coiled tubing operations for multiple wells without repositioning the mast or reel of coiled tubing. The system has a telescoping mast, which is rotationally mounted on a transportable base. The mast is also pivotally attached to the base such that it can be tilted with respected to the base. Further, the mast includes a crown having a receptor configured to receive a coiled tubing injector, wherein the receptor can be rotated and tilted with respect to the mast.
