  • Patent number: 10697243
    Abstract: A coiled tubing rig includes a skid, a mast, and a drill floor. The mast may be pivotably coupled to the skid and may be moved between a horizontal position and a vertical position by a hydraulic cylinder. The drill floor may be pivotably coupled to the mast. The drill floor may be moved from a retracted to a deployed position by a hydraulic cylinder. The skid may include a BOP cradle and BOP controls. The coiled tubing rig may include a jib which may telescopically or pivotably extend from the mast. The coiled tubing rig may include a coiled tubing injector which is slidably positionable between a retracted and a deployed position.

  • Patent number: 7798237
    Abstract: An enclosed coiled tubing apparatus which includes a mobile trailer and a coiled tubing unit releasable coupled thereto, and a enclosure to maintain an adequate temperature, where the coiled tubing unit includes a coiled tubing injector postionally fixed relative to a coiled tubing reel so as to move together relative to the trailer as an integral unit. The coiled tubing reel and injector may travel laterally on the trailer on a track. Also included are methods of extending a wellbore in a subterranean formation by: translating a coiled tubing unit within an enclosure to a first position and then inserting a bottom hole assembly (BHA) into the wellbore using a lifting system, and wherein the coiled tubing unit includes coiled tubing; and translating the coiled tubing unit to a second position and then coupling the coiled tubing to the BHA and operating the BHA to extend the wellbore.
