Abstract: Disclosed herein is a methods and systems for completing a well with fluid—gas and liquid—tight lower completion and an apparatus for doing the same which includes a packer located downhole of a formation isolation well control barrier device and a formation isolation device located downhole of a sand control device.

Abstract: Methods and systems for completing multi-zone formations. One or more embodiments of the method can include placing a gravel pack assembly within a borehole. The gravel pack assembly can include a first sand control extension. A first sand control screen can be disposed adjacent the first sand control extension. The first sand control extension can have a flowpath that is selectively opened and closed. A first isolation packer can be disposed adjacent the first sand control screen. A second isolation packer can be disposed adjacent the first isolation packer. A second sand control extension can be disposed adjacent the second isolation packer. The second sand control extension can include at least a second flowpath that is selectively opened and closed. A second sand control screen can be disposed adjacent the second sand control extension. A lower seal can be disposed adjacent the second sand control screen.

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.

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: Systems and methods for simulating dynamic feedback control systems that include establishing a connection via a common access to a shared memory between the control system logic of a controller to be emulated and a simulation model. State data from a previous simulation associated with the control system logic and the simulation model is retrieved from memory to initialize another simulation run. The state data associated with the simulation model and the control system logic are then synchronized with a timing and control mechanism and a simulation of the controller is executed. A graphical user interface may also be provided to allow a user to adjust the simulation settings and establish new connections with input/output components to be utilized in simulation.
