The apparatus includes a first tubular 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 outwardly extending formations formed on an outer surface of th e 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. In another aspect, a method of compliantly expanding a tubular into contact with a casi ng wall is provided. In a further aspect, an expandable apparatus for expanding a tubular is provided.
