Enventure introduced the ESeal expandable casing patch, a solid-steel liner that seals short sections of damaged casing and perforations. The new technology uses elastomer seals deployed at top and bottom. Once expanded, the elastomer seals anchor the system to the base pipe; cementing is not required before installation. This simple and effective design provides a quick, inexpensive, and permanent seal while reinforcing short casing sections, restoring well integrity, and prolonging the life of the well. The patch has a large effective coverage area, up to 25 ft. The expandable casing patch has high collapse and burst pressure ratings and is a permanent and cost-effective alternative to cement squeezes and legacy remediation methods for restoring casing integrity.
