20090065191 | Support assembly for downhole tool, downhole tool and method - A support assembly for a deformable sealing element of a downhole tool such as a packer, bridge plug or straddle. The support assembly has first and second support devices at each end of the sealing element with each device having an elastically deformable support member adapted to be located between the respective end of the sealing element and an actuating member of the downhole tool. Additionally, a guide member with an inclined guide surface is provided such that the support member travels along the inclined surface when a force is exerted by the actuating member to expand the sealing element radially into abutment with a surface downhole. The support member moves radially outwards to support the respective end of the sealing element during deformation. | 03-12-2009 |

20090294119 | Large bore packer - A retrievable large bore packer for providing an annular seal and an anchor system in a well bore. Ports are provided behind the slips to prevent debris build-up and allow the slips to release. These ports, in a thin walled tubing, allow the collapse of the tubing behind the slips to aid removal of the packer if the sealing element does not release. The slip arrangement is mounted entirely above the sealing element 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. | 12-03-2009 |
