Abstract

An additional string is run through an existing string using a running string. With the strings overlapping an upper inflatable secures them together leaving gaps. The upper inflatable creates an upper expanded zone where the swage assembly is then built. The swage assembly has a seal and upon pressure being applied between the upper inflatable and the seal the swage assembly releases the running string and is pushed to expand the additional string until tagging a cement shoe. The running string is rejoined to the swage assembly and after cementing a lower inflatable is deployed to make a bell and to set an external packer if used. If there is an external packer the shoe releases and on the way out of the hole the upper inflatable sets a seal in the lap.
