ABSTRACT:
A well completion assembly is constructed to be run on a tubing string into a well. The well can be gravel packed and subsequently opened to production without removing the tubing string from the well. The well completion assembly includes a packer, and a screen located below the packer. A gravel packing and production control assembly is located between the packer and the screen for initially permitting flow of gravel packing slurry down the tubing string and into a lower well annulus surrounding the exterior of the screen, and for subsequently permitting production of well fluids through the screen into the interior thereof and up through the tubing string without tripping the tubing string out of the well.
