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.
An apparatus for use in a wellbore, said apparatus comprising: inner tubing and
placed within the wellbore; middle tubing attached to the inner tubing, and further
containing the lower section of the inner tubing; outer tubing containing and concentric
with a portion of the middle tubing; a crossover port for transporting fluid from the inner
tubing through the middle tubing; a port on the outer tubing; and an activator for
controlling the communication of fluid between tubing.
