Packard's Inside Blowout Preventer (IBOP) is used to provide shutoff of backflow during periods when the drill string is open. The valve is held with the dart in the open position to allow stabbing during backflow. After stabbing, the flow is shut off by turning the release handle. Once the stab body is removed the drill string can be reconnected to re-establish pressure stabilization. The valve can then be removed and returned to its ready state or it can be left in the drill string to ensure downward flow only.
