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. The combination of the cup and an untethered object is adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.
