    Well Intervention - Annulus Intervention A4

    Uploaded by

    Arnon Paden
    The document discusses Expro's Annulus Intervention system, which provides remediation of well integrity issues without requiring a workover rig. The system allows for circulation and placement of sealants in pressurized annuli. It offers reduced costs compared to conventional methods by needing a smaller footprint and fewer personnel. Key applications include removing shut-in casing pressure and addressing casing integrity issues. Benefits include increased oil recovery through revitalizing shut-in wells and restoring well integrity and production.
