Abstract
A setting tool has an expansion cone drive sub-assembly operable to axially move an expansion cone of the setting tool through the liner to radially, plastically expand the liner. With the wellbore liner residing outside of a wellbore, the setting tool is changed to enable decoupling the wellbore liner from the setting tool while leaving at least the expansion cone drive sub-assembly substantially assembled.

A method of decoupling a wellbore liner from a setting tool, the setting tool having an expansion cone drive sub-assembly operable to axially move an expansion cone of the setting tool through the liner to radially, plastically expand the liner, the method comprising:
- with the wellbore liner residing outside of a wellbore,
- changing the setting tool to allow a liner latching member of the setting tool to move radially inward and enable decoupling the wellbore liner from the setting tool while leaving at least the expansion cone drive sub-assembly substantially assembled;
- and
- decoupling the setting tool from the wellbore liner.
A method of decoupling a wellbore liner from a setting tool, the setting tool having an expansion cone drive sub-assembly operable to axially move an expansion cone of the setting tool through the liner to radially, plastically expand the liner, the method comprising:
- with the wellbore liner residing outside of a wellbore,
- changing the setting tool to enable decoupling the wellbore liner from the setting tool while leaving at least the expansion cone drive sub-assembly substantially assembled;
- and
- decoupling the setting tool from the wellbore liner, and
- wherein changing the setting tool to enable decoupling the setting tool from the liner comprises changing the setting tool to allow a liner latching member of the setting tool to move radially inward;
- and
- wherein changing the setting tool to enable decoupling the setting tool from the liner further comprises moving a propping member that supports the latching member in engagement with the liner.
A method of assembling a wellbore liner to a setting tool, the setting tool for radially, plastically expanding the liner, the method comprising:
- with an expansion cone of the setting tool, expansion cone drive sub-assembly of the setting tool and liner latching member of the setting tool assembled, assembling the wellbore liner to the setting tool;
- and
- radially extending the liner latching member into engagement with the wellbore liner to couple the wellbore liner to the setting tool.
A setting tool for coupling to a wellbore liner and radially, plastically expanding the wellbore liner in a wellbore, the setting tool comprising:
- a tubular mandrel;
- a wellbore liner expander cone carried on the tubular mandrel and operable to radially, plastically expand the liner when moved axially through an interior of the wellbore liner;
- an expander cone driving sub-assembly carried on the tubular mandrel and operable to axially move the expander cone axially through the wellbore liner to expand the wellbore liner;
- and
- a liner latching member carried on the tubular mandrel and changeable, with the setting tool residing outside of the wellbore, from latched and radially extended into engagement with the wellbore liner to unlatched and radially retracted from engagement with the wellbore liner without disassembling or operating the expander cone driving sub-assembly or disassembling the wellbore liner.
