The purpose of this paper is to provide field experience feedback on achieving surface casing integrity with the use of an expandable steel patch. Casing integrity may be jeopardized during cement remediation or due to mechanical failure. If cement remediation requires casing perforations, then an expandable steel patch can be used to provide pressure integrity across the perforations. If casing integrity is lost due to casing collar leak or corrosion, a similar approach can be used to achieve well integrity. This paper will describe how to restore casing integrity allowing maximum pass-through diameter to continue work over operation
