  • System and Method to Seal by Bringing the Wall of a Wellbore into Sealing Contact with a Tubing
    Publication number: 20060180320
    Abstract: The invention is a system and method used to seal between an open wellbore and a tubing by bringing the wellbore wall inwardly so as to enable sections of earth from the wellbore wall to create the required seal against the tubing. The earth sections that make up the seal can be created by collapsing the relevant parts of the wellbore wall inwardly or by causing the relevant parts of the wellbore wall to swell inwardly.
