Coiled tubing/top drive rig and method

A method of selectively inserting coiled tubing through a rig floor and into a well, the method comprising:

• providing a mast extending upward from the rig base;
• supporting an injector on the mast to insert the coiled tubing into the well, the injector having an injector axis offset from the mast when the injector is in an operative position;
• removably connecting the mast and the injector;
• and powering a drive unit to raise the mast and the injector supported on the mast.

A rig for inserting coiled tubing through a rig floor and into a well, the rig comprising:

• a mast extending upward from the rig floor and movable between a threaded tubular position and a coiled tubing position;
• an injector supported on the mast to insert the coiled tubing into the well, the injector having an injector axis offset from the mast when the injector is in an operative position;
• and
• a powered drive for selectively moving the mast.

• an injector supported on the mast to insert the coiled tubing into the well, the injector having an injector axis offset from the mast when the mast is in the coiled tubing position and the injector is operative;
• a guide rail for guiding lateral movement of the mast with respect to the rig floor between the threaded tubular position and the coiled tubing position;
• and
• one or more fluid powered cylinders for moving the mast laterally.
