Abstract
An apparatus for expanding tubular members in a wellbore, such as casing, liners, sand screens, or other expandable tubular members, includes a first downhole tubular member, a second downhole tubular member that is radially expandable, and a sealed releasable connection coupling the first and second downhole tubular members. The sealed releasable connection is configured to decouple the first and second downhole tubular members by expansion of the second downhole tubular member. The sealed releasable connection had a metal-to-metal seal formed between the first and second downhole tubular members.
