  • Patent number: 9580989
    Abstract: An annular packer to create an annulus seal that includes a solid mandrel with a first end, second end, central bore, and exterior. The annular packer includes first and second sealing elements connected to the exterior. The second sealing element is expanded radially by axial movement of at least a portion of the second sealing element. The annular packer includes a first piston movable from a first position to a second position. Pressure applied exterior of the mandrel moves a portion of the first sealing element away from the mandrel to create a first seal causing a pressure differential. The pressure differential moves the first piston to its second position axially moving at least a portion of the second sealing element to create a second seal against the casing. A port may be opened releasing the first seal, but the second seal remains set against the casing.
