ABSTRACT:
A mandrel for use in a well tubing in which the mandrel body has an open bore for alignment with the well tubing and an enlargement offset from the open bore with a side pocket therein for receiving a flow control device. A combination guard and guide has a body which forms part of the mandrel offset and is positioned above the side pocket to prevent access to the pocket except by a predetermined size member. A projection is provided between the combination guard and guide and the side pocket to assist in retaining a flow control device in position in the pocket. An orienting sleeve is mounted in the open bore of the mandrel above the pocket for aligning a flow control device to be positioned in the pocket, which orienting sleeve comprises a tubular body having a tapered lowered end and a first longitudinal slot angularly disposed relative to the mandrel offset in a predetermined relationship. The first longitudinal slot terminates in spaced relation to the top end of the sleeve and a second slot communicates with the top end of the slot to provide a means for discharging trash and debris from the slot.
