  • Method and apparatus for removing unexpanded shoe
    Patent number: 9080402
    Abstract: A method of removing an unexpanded shoe comprises disposing a tool in a wellbore. The tool includes a latch assembly and a mill body. The latch assembly is engaged with a shoe assembly that is coupled to the wellbore by a tubular having an expanded portion and an unexpanded portion. The mill body is rotated relative to the latch assembly so as to mill the unexpanded portion of the tubular until the shoe assembly is uncoupled from the wellbore. The tool and the shoe assembly are then pulled through the expanded portion and out of the wellbore.

  • Downhole release joint with radially expandable member
    Patent number: 8695699
    Abstract: An apparatus comprises an expansion device that is coupled to a support member and operable to be disposed within a tubular member. The expansion device is operable to radially expand the tubular member as the expansion device moves axially through the tubular member. A latch assembly is coupled to the support member and is operable to engage a corresponding latch receptacle disposed within the tubular member so as to limit the axial movement of the expansion device relative to the tubular member.

  • Downhole release joint with radially expandable member
    Patent number: 8499840
    Abstract: A downhole releasable tubular connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a threaded connection mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, thereby decoupling the tubing strings.
