Abstract (en)
[origin: EP2128377A2] A retrievable large bore packer (10) for providing an annular seal and an anchor system in a well bore. Ports (14) are provided behind the slips (70) to prevent debris build-up and allow the slips (70) to release. These ports (14), in a thin walled tubing (12), allow the collapse of the tubing behind the slips to aid removal of the packer if the sealing element (16) does not release. The slip arrangement is mounted entirely above the sealing element (16) to remove the requirement to seal between the slips and the inner bore of the packer. In this way the packer can have a large bore. Further flow paths are provided through the packer above the seal to prevent debris build-up above the sealing element.
