摘要： A method for expanding a tubular member in a wellbore includes applying a downward force to an expansion cone through a work string to anchor the tubular member in the wellbore and pulling upwards on the expansion cone with the work string to expand the tubular member. The expansion cone is disposed in a launcher portion connected to the tubular member being expanded.

摘要： Methods and apparatus for radially expanding and plastically deforming an expandable tubular include a resilient launcher. The resilient launcher includes a launcher portion and a sleeve portion. An inner diameter of the sleeve portion is smaller than an inner diameter of the launcher portion. An expansion cone is disposed in the launcher portion of the resilient launcher. The expandable tubular is disposed around the sleeve portion and above the launcher portion of the resilient launcher. The launcher portion comprises a port that is sealable below the expansion cone.

摘要： A system comprising a first expandable tubular section and a first expansion bridge coupled to an inner surface of the first expandable tubular section. A base pipe is coupled to the first expandable tubular section and to a second expandable tubular section. A second expansion bridge is coupled to an inner surface of the second expandable tubular section. The system also comprises an expansion cone disposed within and translatable relative to the first expandable section. The expansion cone has an expansion diameter greater than an inner diameter of the first and second expansion bridges and less than an inner diameter of the base pipe.

摘要： Methods and apparatus for radially expanding and plastically deforming an expandable tubular member using a lower expansion cone and an upper expandable cone. The apparatus includes an expandable tubular, a support member releasably secured to the expandable tubular, and an extendable section below where the support member is releasably anchored. An upper expandable cone is attached to the extendable section and in a retracted state and an anchor is disposed below the upper expandable cone. The anchor is releasable from below the upper expandable cone. A lower expansion cone is disposed below the anchor. An expansion sleeve is disposed in the lower end of the expandable tubular. The lower expansion cone is configured to expand the expansion sleeve radially outward to an outer diameter greater than the inside diameter of the expandable tubular when axially displaced downward by the extendable section.

摘要： A system for expanding a tubular member. In some embodiments, the system includes an expansion assembly disposed in sealingly engagement within the tubular member, a shoe assembly releasably coupled within the tubular member, and a chamber disposed therebetween. The expansion assembly has a flowbore and a openable port. The shoe assembly includes a flowbore extending therethrough, the flowbore in fluid communication with the flowbore of the expansion assembly and having a valveable passage. When the valveable passage is closed, the port is adapted to open, whereby the chamber is fluidicly coupled to the flowbore of the expansion assembly. When the valveable passage is open, the port remains closed, whereby the chamber is fluidicly isolated from the flowbore of the expansion assembly.
