ABSTRACT:
A wellbore expandable connection, which includes a tubular pin member having an outwardly facing tapered threaded section and a tubular box member having an inwardly facing tapered threaded section. The threaded sections form a connection of a predetermined integrity when the tubular pin member is mated with the tubular box member. The integrity of the connection is substantially maintained during radial expansion of the connection.
