Abstract
Abstract An orienting mandrel having a pocket for receiving a flow control device and a coacting orienting tool for installing and removing a flow control device from the mandrel pocket. The mandrel having a connection at the top and bottom for attachment to a well tubing with the mandrel pocket positioned directly below the top tubing connection and the mandrel including a bore extending between the tubing connections but including a portion offset from the pocket with the tubing connection at the bottom of the mandrel being in alignment with the offset bore portion, and orienting means in the mandrel coacting with the orienting tool. On downward movement through the well tubing the orienting tool coacts with orientation means in the mandrel for moving the flow control device out of alignment with the pocket thereby allowing the tool to pass through the mandrel, but on upward movement the orienting tool moves into alignment with the pocket for allowing flow control devices to be installed or removed from the pocket.
