Expandable Patch is an in-well repair device made of a special ductile material that, after being run into the well, is mechanically or hydraulically expanded to tightly conform to the inner wall of the casing, providing sealing of damaged sections, restoring structural integrity, and ensuring zonal isolation without significant reduction of the internal diameter.
