Abstract
A method for permanently sealing or bridging perforations disposed in a wellbore that was previously subjected to various completion operations and comprises a plurality of perforated sections comprising a plurality of perforations. In one embodiment, the method comprises configuring a ball injector or multiple ball injectors at the surface of the wellbore, pumping non-degradable perforation ball sealers into the perforated sections via the ball injector, wherein the non-degradable perforation ball sealers permanently seal all perforated sections in the wellbore, and monitoring pressure within the wellbore during operation to determine a successful seal of all the perforated sections.
