Abstract: A plug assembly, dedicated for ball-in-place operation, includes an expandable assembly, a locking ring, a cup and studs, to be deployed using a retrievable setting tool. The expandable assembly is adapted to be deformed radially over the locking ring and the cup, while the locking ring is retained longitudinally relative to a mandrel of the retrievable setting tool, thanks to the studs positioned within the cup. The locking ring has a stopping inner surface.
