Abstract:
A plug assembly includes an expandable assembly and a locking ring. The expandable assembly is adapted to be deformed radially over the locking ring. The plug assembly is used with an untethered object, which is adapted to contact an inside surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause further radial deformation of the expandable assembly, and penetration of an internal surface of the tubing string at least at one point with a gripping portion of the expandable assembly.
