Abstract
An expansion assembly is run into the well as the expandable liner is made up. A work string is tagged into the expansion assembly and run to depth. Pressure drives the swage to initially expand and move uphole with the attached work string until the liner is expanded to set at least one external packer. The balance of the expansion in the uphole direction is continued until the string is expanded into sealing support of a higher string in the wellbore and the variable swage comes out of the hole with the work string. A shoe is milled out and the process can be repeated.
