Find leaks and flowpaths wherever they are, keeps your well safe and productive

Well system integrity depends on the collective performance of the many barriers that form it. A single breach can happen anywhere at any time, and undermine the integrity of the entire system.

Multi Seal evaluates the seal performance of multiple barriers, locating leaks and flowpaths throughout the well system, from the wellbore to the outer annuli.


Delivered by our True Integrity system with Chorus technology, Multi Seal provides a clear diagnosis of leaks and rogue flowpaths so the right corrective action can be taken.


Multi Seal is used in a targeted fashion to investigate a known integrity breach anywhere in the well system. Barriers can also be validated proactively to confirm integrity. Either way, Multi Seal provides the insights needed to restore or maintain a secure well.

Multi Seal Integrity provides a clear and complete diagnosis of leaks and unwanted flowpaths, so you can take the right action.
