  • Patent number: 8651192
    Abstract: A bottom hole assembly (BHA), adapted to be positioned in a casing and to isolate a portion of a wellbore, which includes a packer assembly with a first sealing element extending between first and second portions of the packer assembly. A method of setting a BHA in a casing which includes increasing a BHA pressure to activate an anchor assembly, applying a mechanical force to mechanically deform a first sealing element to thereby establish an initial seal between the first sealing element and an interior surface of the casing, and increasing a pressure in a space between the BHA and the casing and in a cavity within the BHA to increase a differential pressure across the first sealing element and thereby establish a pressure-energized seal between the first sealing element and the interior surface of the casing.

  • Patent number: 8302692
    Abstract: A sand slurry valve that includes a mandrel within a housing and a seal assembly connected to the mandrel. A portion of the housing includes a seal bore. The mandrel is movable within the housing such that the seal assembly may be positioned within the seal bore. The mandrel includes a flow passage adapted to provide rotational fluid flow through the housing prior to the seal assembly being moved into the seal bore. The seal assembly may include a seal, a first backup ring, and a second backup ring with the second backup ring positioned between the seal and the first backup ring. The rotational flow through the housing may help to protect the seal from being damaged by particles carried within the flow. The first backup ring may have a harder durometer measurement than the second backup ring, which may have a harder durometer measurement than the sealing element.
