Abstract
A method includes providing a retrievable plug assembly at a surface of an oil or gas well, the plug assembly having a seal element that has an original outer diameter. The method also includes stretching the seal element so that the outer diameter is less than the original outer diameter and then placing the plug assembly between first and second zones formed within the tubing string. The method also includes removing any tensile axial load on the seal element so that it shrinks back towards its original outer diameter while positioned between the first and second zones. The method also includes compressing the seal element so that the seal element sealingly engages an inner surface of the tubing string to isolate the first zone from the second zone.
