Abstract

A technique facilitates patching of a tubing (), e.g. casing (), in a downhole environment (). The technique employs a patching system comprising a plurality of expansion rings (). The expansion rings () are moved downhole to a patch zone () along the tubing (). Once in a desired position at the patch zone, the expansion rings () are expanded into engagement with an inner surface of the tubing. For example, the expansion rings may comprise seal elements () and/or anchor elements which are expanded into engagement with the inside surface. The patching system further comprises a patch () which may have a tubular shape. The patch is radially expanded in a manner which maintains a sealing engagement with the plurality of expansion rings () to create a sealed patch across a desired region in the patch zone.
