Abstract
Assemblies and methods are provided for retrieving a sealing assembly from within a tubing string positioned downhole in a wellbore. The sealing assembly may include a plug that may include a non-elastomeric material at least partially surrounding an elastomeric material. The sealing assembly may be run downhole in the wellbore with the plug at an original diameter. The sealing assembly may be set such that the plug is expanded to a set diameter. The retrieval tool may be coupled to the sealing assembly and may be extended in a first direction. The extension of the retrieval tool may lengthen the sealing assembly. The lengthening of the sealing assembly may extend the length of the plug and may thereby reduce the diameter of the plug. In some aspects, the retrieval tool may reduce the diameter of the plug back to the original diameter.
