Abstract
A kickover tool is disclosed for installing and retrieving a well flow control device from a side pocket mandrel in a wellbore. The kickover tool includes a spring-loaded key which has an outer circumferential surface having a predetermined machined pattern formed therein. Each side pocket mandrel in the tubing string contains a profile having a predetermined machined pattern. The spring-loaded key will engage the side pocket mandrel with a profile matching the pattern on the outer circumferential surface of the spring-loaded key. When that engagement occurs, the articulated arm of the kickover tool is permitted to be deployed to insert a well flow control device in the side pocket of the side pocket mandrel.
