Expandable tubular technology has in recent years proved to be effective for liner hangers as well as casing repairs, according to Tommy Van, TIW regional salesman. "Initially, we were looking for expandable technology that would give us the hanging capability for both short and long liner applications that also would give us a HP/HT seal at the liner top," Van says. As a result, TIW design engineers and operational personnel designed and tested a new expandable hanger concept called the X-Pak Expandable Liner Hanger System." It uses a tie-back expander working in conjunction with the X-Pak Hanger Body, and when set, forms an HP/HT seal.
