  • Patent number: 5865253
    Abstract: An overshot for engaging and retrieving a collapsed coiled tubing in a wellbore, has been invented. In one aspect the overshot has a body member with a top, a bottom, and a body channel therethrough from top to bottom, the body member having a slip chamber, at least one slip movably disposed in the slip chamber of the body member, and movable on at least one inclined rail in the slip chamber so that, upon contacting the collapsed coiled tubing, upward movement of the body member results in downward movement of the at least one slip which also moves the at least one slip inwardly in the body member thereby increasing gripping force of the at least one slip on the collapsed coiled tubing. Methods have also been invented for using such overshots.

  • Patent number: 5794314
    Abstract: A holder for holding collapsed coiled tubing has been invented which, in one aspect, has a first plate, a second plate, securement apparatus for releasably securing the plates together in a spaced-apart relationship about at least one portion of a collapsed tubular, e.g. but not limited to coiled tubing, and at least one gripper or gripping element on one plate for gripping the collapsed tubular between the first plate and second plate. In one aspect such a holder has gripping elements which include a first die device on the first plate and a second die device on the second plate, the first die device disposed opposite the second die device when the holder is installed around a collapsed tubular. In one aspect dies are longitudinally offset with respect to upper and/or lower dies so that gripping is achieved across a wider portion or substantially all of the width of a collapsed tubular. In one aspect such a holder is an elevator with an elevator hook on each plate so the holder serves as an elevator.
