Abstract
A wellbore completion system includes an expandable liner hanger with a post-setting fluid flow path. The system includes an expandable liner hanger that can be expanded by a running tool prior to a completion operation in a wellbore. The system also includes a circulating sleeve that can be manipulated by the running tool. The circulating sleeve can provide a return path for fluid internal to the expandable liner hanger for the completion operation that is performed subsequent to releasing the running tool from the expandable liner hanger.
