Abstract:
1. A system for conducting earth borehole operations comprising: a coiled tubing (CT) carrier; a mast carrier separate from said CT carrier; a reel of CT rotatably mounted on said CT carrier whereby said mast carrier and said CT carrier can be transported independently of one another to different sites; a mast mounted on said mast carrier and movable between a lowered position for transport and a position transverse to the horizontal; a top drive carried by said mast, said top drive being longitudinally movable along said mast; and a CT injector on said mast carrier, said CT carrier and said mast carrier being selectively, pivotally attachable to one another whereby said CT carrier can be positioned at a desired angle relative to said mast carrier, wherein when said CT injector is attached to said mast to insert CT into a wellbore, said CT injector has a CT injector axis offset from the axis of the top drive and substantially aligned with the axis of the borehole when the mast is in a position to perform CT operations.
