Abstract: A method and apparatus for conducting earth borehole operations comprising a CT system comprising a first carrier with a reel of CT and a CT injector, a second carrier comprising a top drive rig having a mast, and a lifter operative to move the CT injector from the first carrier to an operative or near operative position with respect to the mast on the second carrier.

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.

Abstract: An apparatus for conducting earth borehole operations, comprising a base, a mast mounted on the base, and an integrated unit comprising a top drive and a coil tubing injector carried by the mast for longitudinal movement therealong. The top drive has an opening therethrough whereby coil tubing from the injector can pass through the top drive. There is a guide for coil tubing, the guide being selectively releasably connected to the coil tubing injector and mounted on the mast and selectively movable between a first position wherein coil tubing from the guide can be stabbed into the injector and a second position wherein coil tubing from the guide is out of alignment with the coil tubing injector.

Abstract: Mobile drilling rig 10 includes a carrier frame 14 and a mast 12 supported on the frame. A top drive 16 is supported on the mast when in an operative position, and a coil tubing injector 20 is supported on the mast when in an operative position. A first dolly assembly 22 and a second dolly assembly 60 are provided each for supporting a portion of the carrier frame, and include a first plurality of wheels on a first plurality of axles. Each dolly assembly is adaptive for selective attachment to and detachment from the carrier frame, so that the dolly assemblies may be changed out for compliance with regulations and road conditions.

Abstract: A coiled tubing transfer system comprising a carrier having a bed, the bed having a width and the length, the length of the bed being longer than the width of the bed, a reel removably supported on the bed, the reel comprising a spool rotatably journaled in first and second supports, the spool having a core with a diameter and long axis extending between the supports, the long axis having a length greater than the width of the bed, the reel being positionable on the bed in a first position with the long axis of the core extending lengthwise of the bed, the longest dimension of the reel transverse to the long axis of the core being less than the width of the bed and a length of coiled tubing useable in earth borehole operations being wound around the core, the coiled tubing having an outside diameter of from 1? to 9?, the ratio of the diameter of the coiled tubing to the diameter of the core being from 1:20 to 1:70.

Abstract: The rig for selectively inserting coiled tubing or a threaded tubular through a rig floor 13 and into a well includes a mast 15 extending upward from the rig floor and movable between a threaded tubular position and a coiled tubing position. A top drive 21 is movable along an axis of the mast to insert the threaded tubular in the well when a top drive axis 42 is substantially aligned with the axis 44 of the well. Injector 17 supported on the mast inserts coiled tubing into the well, with the injector having an axis 46 offset from the top drive axis and substantially aligned with the axis of the well when the mast is in the coiled tubing position. A powered drive 54 is provided for selectively moving the mast between the threaded tubular position and the coiled tubing position.

Abstract: A lubricator for use with a coiled tubing injector comprising an elongated housing having a first end and a second end, a guide system disposed in the housing for guiding coiled tubing passing through the housing, a first directo proximal the first end of the housing to direct the coiled tubing in a first direction and a second director proximal the second end of the housing to direct the coiled tubing in a second direction.

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.

Abstract: The rig (10) is provided for electively inserting either coiled tubing or a threaded tubular through a rig floor and into a well. The rig includes a coiled tubing injector (16) supported on a mast (14) when in an operative position to insert coiled tubing into the well, and a top drive (18) movable along an axis of the mast when in an operative position to insert the threaded tubular into the well. The rack or support (20) is secured to the mast for receiving a plurality of substantially vertical threaded tubular joints therein when the mast is in an operative position. Tubular joints may be moved between the top drive and the tubular support when running threaded tubulars into or out of the well.

A top drive 21 is movable along an axis of the mast to insert the threaded tubular in the well when a top drive axis 42 is substantially aligned with the axis 44 of the well. Injector 17 supported on the mast inserts coiled tubing into the well, with the injector having an axis 46 offset from the top drive axis and substantially aligned with the axis of the well when the mast is in the coiled tubing position. A powered drive 54 is provided for selectively moving the mast between the threaded tubular position and the coiled tubing position.
