Abstract
A system includes an inner string assembly disposed within an outer casing. The inner string assembly includes a seal member in sealing engagement with the outer casing. An expansion sleeve is coupled to an end of the outer casing. An expandable liner is coupled to the expansion sleeve. A cone assembly is coupled to the inner string assembly and positioned proximate to the expansion sleeve when the inner string is in a running position.
Claims17
A system comprising:
- an outer casing;
- an inner string assembly, wherein the inner string assembly includes a seal member in sealing engagement with the outer casing;
- an expansion sleeve coupled to an end of the outer casing;
- an expandable tubular coupled to the expansion sleeve;
- a cone assembly coupled to the inner string assembly, wherein the cone assembly is positioned proximate to the expansion sleeve when the inner string is in a running position;
- and
- a safety sub assembly coupled to an upper end of the outer casing and including a coupling for connection to a conveyance.

A method, comprising:
- assembling an expansion system, the expansion system comprising an outer casing, and an inner string assembly, wherein the inner string assembly includes a seal member in sealing engagement with the outer casing;
- coupling a first expansion sleeve coupled to an end of the expansion system;
- coupling a cone assembly to the expansion system, wherein the cone assembly is positioned proximate to the first expansion sleeve when the expansion system is in a running position;
- coupling a first expandable tubular to the first expansion sleeve;
- connecting the expansion system to a conveyance;
- positioning the first expandable tubular in a wellbore with the conveyance;
- expanding the first expandable tubular in the wellbore to an expanded diameter;
- shifting an expansion cone of the cone assembly from a collapsed configuration to an expansion configuration in which the expansion cone has an outer diameter that is greater than an outer diameter of the outer casing;
- and
- passing the expansion cone out of the first expandable tubular and collapsing the expansion cone.
