  • System and method for maintaining zonal isolation in a wellbore
    Patent number: 7669653
    Abstract: The invention concerns a system or a method for maintaining zonal isolation in a wellbore. According to the invention, the system comprises, at a specific location along said wellbore, a sealing element, said sealing element being able to deform both during and after placement and is maintained after placement under compression through a pressurizing fluid or by confinement in a volume.
    Type: Grant
