Abstract
A completion system that is usable with a well may include a packer, a screen, an isolation valve and an annulus communication valve. The screen communicates well fluid between an annulus of the well and an interior passageway of the completion system. The isolation valve is radially disposed inside the screen to control communication through the screen between the annulus and the interior passageway. The annulus communication valve is located downhole of the packer and uphole of the screen to control communication with the annulus of the well. The packer, screen, isolation valve and the annulus communication valve are adapted to be run downhole as a unit into the well as a single trip completion.
