Kickover tool and selective mandrel system

A kickover tool for installing and retrieving a well flow control device from a side pocket mandrel in a wellbore, comprising:

• a generally tubular-shaped housing;
• a slider bar having proximal and distal ends which is inserted in and releasably attached to said housing;
• a spring-loaded key which is cooperatively attached to the housing, where the spring-loaded key comprises a plurality of springs and has inner and outer circumferential surfaces, the inner circumferential surface of the spring-loaded key engaging the slider bar when the springs are compressed to prevent the slider bar from moving and the outer circumferential surface of the spring-loaded key having a predetermined machined pattern formed therein;
• a spring-loaded dog which is cooperatively attached to the housing, where the spring-loaded dog comprises a plurality of springs and has inner and outer circumferential surfaces, the inner circumferential surface of the spring-loaded dog engaging the slider bar when the springs are compressed to assist in preventing the slider bar from moving;
• and
• an articulated arm having two ends where one end is operatively coupled to the distal end of the slider bar and the other end is operatively coupled to the well flow control device to be inserted in the side pocket mandrel.
