  • Patent number: 7640977
    Abstract: A technique is provided to facilitate connection of multiple stage completions. A first completion stage is deployed at a wellbore location. Subsequently, the next completion stage is moved downhole into engagement with the first completion stage. The completion stages each have communication lines that are coupled together downhole via movement of the completion stages into engagement.

  • Patent number: 7591321
    Abstract: Zonal isolation tools and methods of using same are described. The zonal isolation tools include a wellbore sealing member expandable by fluid pressure to contact a wellbore over an initial contact area, an inflation valve open during expansion of the sealing member to the initial contact area and closed upon the fluid pressure reaching a predetermined setting, a vent between the sealing member and a wellbore annulus adapted to open after the inflation valve is closed, and a compressive load imparted to the sealing member via a linear piston to achieve a sealing point at the leading edge of the sealing member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Patent number: 7510003
    Abstract: A technique is provided in which a soft landing system is used for connecting upper and lower assemblies in a wellbore. The soft landing system cushions the engagement of an upper well assembly with a lower well assembly and facilitates the controlled engagement of control line connectors. The controlled engagement limits or avoids damage to the control line connectors in well completion operations performed in two or more stages.

  • Patent number: 7503395
    Abstract: A technique is provided to facilitate connection of well equipment assemblies at a downhole location. A first assembly comprises a control line having a connector designed for coupling with a corresponding connector of a next adjacent assembly. Additionally, a mechanism is provided to restrain movement of the next adjacent assembly prior to full engagement with the first assembly to enable performance of a desired preparation procedure.

  • Patent number: 7451825
    Abstract: An apparatus that is usable with a well includes a tubular member, an annular body and plugs. The tubular member includes a wall that defines a passageway to communicate a fluid, and an opening extends through the well. The annular body circumscribes the wall, and the annular body includes orifices that are adapted to communicate the fluid with the opening. The plugs are adapted to be moved to controlled positions relative to the orifices to regulate at least one of a flow rate of the fluid through the opening and a pressure differential across the opening.

  • Patent number: 7398822
    Abstract: A technique is provided in which a contraction joint is used to facilitate connection of well equipment assemblies at a downhole location. The contraction joint accommodates changes in system length during engagement and use or the well equipment assemblies in a wellbore. Additionally, the contraction joint provides a positive indication of joint position and enables resetting of the joint following initial contraction.

  • Patent number: 7306043
    Abstract: The invention is a system and method a system used to control multiple downhole tools with one control line. The downhole tools may comprise any hydraulically actuated tools, such as valves, packers, or perforating guns. Each tool is associated with an indexer, in one embodiment, so that the tools can be operated in concert and as a system.

  • Patent number: 7182139
    Abstract: A system and method is provided for integrated control of multiple well tools. Predetermined pressure levels are utilized in independently actuating specific well tools from a plurality of well tools. The number of well tools independently controlled may be greater than the number of fluid control lines that cooperate with the well tools to control tool actuation.
