  • Patent number: 8739870
    Abstract: A system having a sealing assembly for a gravel port in a gravel pack apparatus. The sealing assembly includes a sealing element around an outer circumference of the gravel pack assembly above the gravel pack and below the gravel port. The sealing element is on the outside housing of the gravel pack apparatus or on a separate piece of equipment located above the gravel pack and below the gravel port, permitting a larger flow bore through the gravel pack apparatus. The sealing element may be selectively actuated after the gravel pack operation has concluded, thus maintaining the gravel pack in the desired location. The removal of a gravel pack tool may permit the sealing element to be actuated.
