  • Patent number: 7562709
    Abstract: A gravel pack apparatus for use in a wellbore includes a screen assembly to filter particulates, at least one shunt conduit to carry gravel slurry, and a swellable element around a portion of the at least one shunt conduit. The swellable element swells in response to an input stimulus and expands radially outwardly to seal against the wellbore.

  • Patent number: 7066264
    Abstract: A service/completion liner having a plurality of downhole selectable indicating tools and being used in sand control (gravel pack) placement systems in conjunction with a straddle packer service tools or with conventional crossover type service tools. Each indicating collar has a downhole selectable indicating collar providing a robust, landing profile for precisely locating and maintaining service tool position during well treatment operations. The landing collars accommodate hydraulic and/or thermal effects commonly referred to as tubing move effects which are the principle cause of tool position error and excessive seal wear. The landing collar is downhole convertible between a pass through (Go) and non pass through (No-go) condition by simple upward and downward cycling via the tool running and treatment fluid tubing and a shifting tool, which may also be referred to as a set down collet.
