Drilling rig apparatus and downhole tool assembly system and method










Image Number 5 for United States Patent #6973979.

A drilling rig is provided which is adapted to selectively drill using coiled tubing and jointed-pipe. The rig includes a base, a mast, a top drive slidably mounted to said mast for performing jointed-pipe operations, and a tubing injector for performing coiled tubing operations, mounted on said mast for selective movement from a first position in which the injector is in line with the mast and a second position in which the injector is out of line with the mast to permit jointed-pipe operations by the top drive. The rig is uniquely suited to easily and quickly assemble bottom hole assemblies (BHA's), and to connect such BHA's to coiled tubing.
