Abstract

Abstract A well completion apparatus for use in a wellbore, the apparatus comprising: inner tubing (414) and placed within the wellbore; middle tubing (416) attached to the inner tubing (414), and further containing the lower section of the inner tubing (414); outer tubing (404) containing and concentric with a portion of the middle tubing (416); a crossover port (440) for transporting fluid from the inner tubing (414) through the middle tubing (416); a port (424) on the outer tubing (404); and an activator for controlling the communication of fluid between tubing. This provides a multi-zone packing system having features that allow for remote operation, thereby eliminating the need to raise and lower a work string and crossover tool to various zones of interest during a frac pack, gravel pack or related completion procedure.
