Abstract

Methods relate to tubulars that may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.
