Abstract
Dissolvable casing liners are utilized to isolate existing perforations. A dissolvable casing liner is deployed downhole along the interior of a casing string having a plurality of perforations. The casing liner is then secured against the casing string, thereby effectively sealing the perforations. Once the perforations are isolated, refracturing operations may be conducted. At some time thereafter, the casing liner is dissolved and removed from the wellbore.
