In accordance with an illustrative embodiment of the present invention, a side pocket mandrel having a side pocket laterally offset from the open bore has an opening at the upper end of the pocket adapted to receive a gas lift valve. The axis of the opening is inclined in a downward and inward direction toward the axis of the open bore. A kickover tool for replacing and removing valves includes an orienting section having angularly spaced dogs that are cooperable with a sleeve in the mandrel to cause orientation of the tool and to trigger longitudinal movement of a control rod. Rod movement actuates guides on a pivot arm that cooperates with rails or the like in the mandrel to cause the valve to be inserted through the opening to a position extending upwardly into the annulus with a packing sub thereon engaging the opening.

A side pocket mandrel adapted to be connected in a tubing string, comprising: a body having an open bore aligned with the bore of the tubing and a side pocket laterally offset from said open bore; a cylindrical opening through a wall of said body at the upper end of said pocket, said opening having an axis that is inclined with respect to the longitudinal axis of said open bore; and surface means on said body for orienting a kickover tool in a manner such that a flow control device attached thereto can be positioned for entry into said side pocket and eventual insertion into said opening. A kickover tool apparatus for use in placing and removing flow control devices in and from a side pocket mandrel, comprising: orienting means having upper and lower outwardly projecting dog means that initially have a predetermined angular relationship to one another and means allowing a change in said angular relationship; tray means connected to the lower end of said orienting means and having normally retracted kickover means mounted thereon; control means movable longitudinally relative to said tray means for releasing said kickover means for outward movement; and release means included in said orienting means responsive to a change in said angular relationship of said dog means for allowing longitudinal movement of said said control means.
