1. A rig for selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well, the rig comprising:
- a mast extending upward from a rig base when in an operative position;
a coiled tubing carrier supporting a coiled tubing injector and a coiled tubing reel during transport, the coiled tubing carrier being structurally separate from the rig base;
the coiled tubing injector supported along the mast when in an operative position to insert the coiled tubing into the well;
a top drive movable along the mast when in an operative position to insert the threaded tubulars into the well; and
the mast being pivotable on the rig base to attach the coiled tubing injector while supported on the coiled tubing carrier to the mast, such that the coiled tubing injector is raised to the operative position when the mast is raised.

Abstract
A rig (10) for selectively inserting coiled tubing or threaded tubulars into a well includes a mast (14) extending upward from a mast carrier (12), and a coiled tubing injector (16) and a coiled tubing reel (26) supported on a coiled tubing carrier (28) separate from the mast carrier. The mast (14) may be pivotal on the mast carrier to attach the coiled tubing injector 16 to the mast while the injector is supported on the coiled tubing carrier.

10. A rig for selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well, the rig comprising:
-
a mast extending upward from a rig base when in an operative position; a top drive movable along an axis of the mast when in an operative position to insert the threaded tubulars into the well; a coiled tubing carrier supporting a coiled tubing injector and a coiled tubing reel during transport, the coiled tubing carrier being structurally separate from the rig base; the coiled tubing injector supported along the mast when in an operative position to insert the coiled tubing into the well; and one or more fluid pressure cylinders for pivoting the mast relative to the rig base to attach the coiled tubing injector while supported on the coiled tubing carrier to the mast, such that the coiled tubing injector is raised to the operative position when the mast is raised. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of transporting a rig and selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well, the method comprising:
-
extending a mast upward from a rig base when in an operative position; supporting a coiled tubing injector and a coiled tubing reel on a coiled tubing carrier during transport, the coiled tubing carrier being structurally separate from the rig base; supporting the coiled tubing injector on the mast when in an operative position to insert the coiled tubing into the well; moving a top drive along the mast when in an operative position to insert the threaded tubulars into the well; and pivoting the mast on the rig base to attach the coiled tubing injector while supported on the coiled tubing carrier to the mast, such that the coiled tubing injector is raised to the operative position when the mast is raised. - View Dependent Claims (17, 18, 19, 20)
