Abstract
A system for conducting earth borehole operations comprising a CT carrier, a reel of CT rotatably mounted on the CT carrier, a mast carrier, separate from the CT carrier, a mast mounted on the mast carrier and movable between a lowered position for transport and a position transverse to the horizontal, a top drive carried by the mast, the top drive being longitudinally movable along the mast and a CT injector on the mast carrier.
Claims15
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, wherein when said CT injector is attached to said mast to insert CT into a borehole, said CT injector has a CT injector axis offset from an axis of the top drive and substantially aligned with an axis of the borehole when the mast is in a position to perform CT operations.

A system for conducting earth borehole operations comprising:
- a coiled tubing (CT) carrier;
- a mast carrier separate from said CT carrier, said mast carrier including a substructure portion;
- 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 substructure portion, said CT injector being selectively movable from a position on said substructure portion detached from said mast to a position attached to said mast, wherein when said CT injector is attached to said mast to insert CT into a borehole, said CT injector has a CT injector axis offset from an axis of the top drive and substantially aligned with an axis of the borehole when the mast is in a position to perform CT operations.
