Abstract: A pack-off device, including a body having a first feedthrough and a second feedthrough formed therein. A projection extends from the body and is operatively arranged to engage a restriction of an adjacent structure. At least one seal element is arranged with the body for sealing the device against the adjacent structure when the projection is engaged with the restriction. A method of arranging and operating a completion system is also included.

Abstract: An assembly of inflow control devices on a string along with isolation devices can be delivered into an existing or newly delivered screen assembly that requires inflow control for balanced flow from the formation. In newly delivered screen assemblies, any gravel packing that needs to be done can be accomplished without the presence of the inflow devices for faster circulation and improved gravel deposition. External annular barriers can also be delivered with an original screen assembly in a new well installation. The inflow devices and barriers can be of a variety of designs and the internal string can be removable if the barriers are retrievable to facilitate further drilling or completion below the screen assembly.
