  • Patent number: 9353604
    Abstract: Systems and methods for completing a well. A lower completion assembly is run into a wellbore adjacent to a subsurface formation in a single trip. The lower completion assembly includes a screen assembly, an inner string, and a sealing device. The inner string has a return opening and at least one inflow control device communicating with an interior of the inner string. The barrier device actuates between a gravel packing position and an inflow control position. Gravel flows about the screen assembly with the barrier device in the gravel packing position during at least a portion of gravel pack operations. The barrier device is actuated to the inflow control position to restrict flow through the screen assembly during at least a portion of a well operation.
    Type: Grant

  • Patent number: 8066071
    Abstract: Apparatus for multi-zone wellbores that can by-pass upper hydrocarbon bearing zones and deliver fluid to lower hydrocarbon bearing zones. The apparatus can include at least one housing, and at least one port can be formed through the housing. An inner sleeve can be positioned within the housing. At least one cavity can be radially disposed on an outer diameter of the inner sleeve, and each cavity can be located within an annulus formed between the inner sleeve and the housing. A ball can be disposed within each cavity, and the ball can be adapted to selectively engage the port.
