ABSTRACT:
An expandable slip ring is used to secure attachment of an expanded tubular to a surrounding tubular. It features elongated generally axially oriented openings separated by narrow segments. As a swage is advanced within a tubular that has the slip ring outside it the narrow segments or tabs expand and can break but the ring is still held to its shape as the expansion progresses due to the integrity of other tabs that can subsequently break as the swage advances within the tubular that is surrounded by the slip ring. The integrity of the slip ring is enhanced for storage and run in while the expansion characteristics are more uniform as the ring retains some structural integrity during much of the expansion process.
