Remedial systems designed to restore casing or tubing integrity by sealing leaks, corroded sections, or damaged connections.
Welltec solution benefits
Patch-thru-Patch solutions restore casing or tubing integrity by sealing leaks, corroded sections, or damaged connections while maintaining well access and production efficiency.
Combining slim, high-pressure expandable designs with rigless, wireline-deployable deployment, these patches provide reliable remediation across a range of well conditions. Multiple patches can be installed in the same section, minimizing downtime and avoiding costly workovers.
Leaks and Corrosion
Seal leaks and corroded sections in casing or tubing for restored well integrity.
Unwanted Inflow/Outflow
Prevent production losses or unwanted fluid movement through perforations or damaged zones.
Protection of Downhole Hardware
Safeguard casing, tubing, and other downhole components during and after remediation.
Patch-Thru-Patch Remediation
Enable multiple patch installations in the same section for flexible future interventions.
Our Patch-thru-Patch solutions are rigless and wireline-deployable, allowing rapid installation without the cost or complexity of conventional workovers. The variety of patch types—including Isealate Springblade Patch and Welltec® Delta Xpander Internal Patch (WDX-IP)—ensures that every well challenge, from leaks and corrosion to unwanted inflow/outflow, can be addressed with the right solution.
Patch-thru-patch-capable designs enable multiple patches to be installed in the same section, providing flexibility for future interventions and minimizing downtime. Beyond sealing, these solutions protect tubing, casing, and downhole hardware, maintaining long-term well integrity.
Patch-thru-Patch solutions simplify complex well repairs, delivering quick, efficient, and rigless remediation.
