Abstract
The assembly is supported and operated by a tubing string and includes an hydraulically set packer carrying a production screen and a removable gravel pack apparatus. The packer is set, gravel is packed about the screen and the gravel pack apparatus is then removed from the set packer by disengaging a pin and slot connection. The gravel pack apparatus and attached screen may be subsequently re-engaged with the packer for regraveling. The packer is equipped with resilient seal means and a plurality of radially movable anchoring slips which are set in sealing and anchoring engagement, respectively, with a surrounding well conduit by an hydraulic setting mechanism. The gravel pack apparatus cooperates with the set packer to form a series of separate, axially extending, flow passages which may be selectively opened or closed.
