ABSTRACT:
A well installation having a locator tool for installing or removing well apparatus into or from a well sub in a well tubing. The locator tool moves through the well tubing, such as by wireline or fluid pumpdown. One feature is the actuation of the locator tool by a single downward and upward movement of the locator tool by engaging an upward shoulder in a well sub thereby avoiding multiple reciprocation of the well tool which is particularly disadvantageous in pumpdown operations. Another feature is providing a distinctive configuration on the well tool and a corresponding coacting configuration on one sub whereby the well tool may be selectively actuated in the one well sub in a well tubing having a plurality of subs. Another feature is the provision of coacting orientation means between the locator tool and a well sub for orienting a well apparatus in the well tubing. Another feature is the provision of a selective configuration in the well sub by a narrow selective configured slot which avoids the use of annular grooves which might interfere with other well operations. A well mandrel and kickover tool is provided for installing or removing flow control devices from the mandrel in which one or more of the above-mentioned features is provided.
