Abstract: An intelligent well system may include a first main bore transmission assembly disposed in a main bore and a first lateral bore transmission assembly disposed in a lateral bore. The first main bore transmission assembly may include a first main bore transmission unit, and the first lateral bore transmission assembly may include a first lateral bore transmission unit. The first main bore transmission unit and the first lateral bore transmission unit may be configured to establish a wireless connection there between, such that at least one of power or telemetry can be wirelessly transmitted. The first main bore transmission assembly may be configured to be communicatively connected to a surface communication device.

Abstract: A system for communicating with downhole components is provided comprising at least one RFID device configured with an identification code. The system further includes a device conduit extending next to the downhole components and a device propulsion system configured to translate the RFID devices next to the downhole components to facilitate an exchange of information between the downhole component and the RFID device. The device conduit may include a check valve or a turn-around sub depending upon the application. In some cases, the exchange of information may trigger actuation of one or more of the downhole components. A method is also provide comprising providing a device conduit near downhole components, propelling an RFID device near to the downhole components via the device conduit and a device propulsion system, and exchanging information between the RFID device and the downhole components.

Abstract: A system that is usable with a well includes a closed loop network that is located entirely downhole in the well. The system also includes valves that are located in a wellbore of the well and are interconnected by the closed loop network. Each valve is associated with a different isolated region of the wellbore and is adapted to regulate a flow through the valve based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other isolated regions.

Abstract: An apparatus and method of forming a barrier to fluid flow behind a liner are provided. In one embodiment of the invention, a method includes the steps of conveying a tool to a position within a wellbore having a liner, the tool carrying a seal material, and injecting the seal material from the tool through the liner to form a barrier to fluid flow behind the liner. In another embodiment of the invention, the apparatus includes a housing having a chamber carrying a seal material, and a means for injecting the seal material through the wellbore liner.
