• Plug Holder

    Description

    The plug holder retains the liner wiper plug with integrated ball seat during the setting of the liner hanger and cementing of the liner until the wiper plug is released from the plug holder by the drill-pipe dart. A second feature of the plug holder is to act as a pick-up to shear and retrieve the shear pins of the sleeves from the retrievable packoff bushing. The plug holder with integrated equalizing valve prevents the premature release of the liner wiper plug from the plug holder and provides a clearer indication when releasing the liner wiper plug by the drill-pipe dart. In addition, plug holders are required to release and retrieve the packoff bushing.
