摘要：
The tubular string to be expanded is run in on a running string. The swage assembly has a seal from the running string to the existing tubular and the top of the tubular string to be expanded also has a similar seal against the exiting tubular. Annulus pressure around the running string drives the swage assembly to support the expanded tubular to the exiting tubular and to continue expansion to the end of the tubular. Cementing then takes place followed by reconfiguring the swage assembly to engage the liner hanger seal with the result being a monobore connection in a single trip including the cementing.
