  • Downhole zone isolation system
    Patent number: 6983795
    Abstract: A gravel packing system featuring pressure actuated sliding sleeve valves mounted to an exterior annulus around a blanking pipe for screen sections is disclosed. An internal sliding sleeve valve is provided for subsequent closure of access through the screens. The presence of the annulus between the blanking pipe and the screen permits a backup access through perforating the blanking pipe while not damaging the screen. The sliding sleeve valves that are mounted internally and externally on the blanking pipe are removable apart from the screen section that already has gravel packed around it, if they fail to operate and need repair.
