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.

Abstract: An apparatus for installing and removing flow valve in a well tubing having a plurality of valve receiving side pockets offset from the main bore of the tubing by providing an orientation sleeve with a first slot for directing a guide key of a valve handling apparatus in the sleeve and a second slot intersecting the first slot to assist in removal of debris from the first slot with spaced aligned shoulders in the sleeve at the intersection of the first and second slots for actuation of the valve handling apparatus. The valve handling apparatus includes a support body including an elongated cylindrical body member supporting a movable body comprising an elongated plunger telescopically and nonrotatably arranged in the support body.

Abstract: A mandrel for use in a well tubing has a body with a bore extending therethrough for alignment with the well tubing with a valve pocket offset from the mandrel bore for receiving a valve or other tool therein and guard and guide means for particular configuration are formed at the upper end of said pocket to restrict access thereto and includes projection means to assist in retaining valves in position in the valve pocket.
