Abstract
An apparatus for forming an expanded connection in a wellbore, whereby the apparatus includes a first tubular being radially expandable outward into contact with an inner wall of a second tubular upon the application of an outwardly directed force supplied to an inner surface of the first tubular. The apparatus further includes a plurality of formations formed on an outer surface of the first tubular, the formations constructed and arranged to provide a frictional relationship between the first tubular and the second tubular while leaving a fluid path when the first tubular is expanded to engage the inner wall of the second tubular.
