Abstract
An anchor tool and cooperating anchor positioner for use in a well bore are disclosed. The anchor tool may be employed as part of a well casing or liner, while the anchor positioner is part of a tool string run inside the casing or liner. The anchor positioner locates and anchors the tool string at a desired level in the well bore by engagement with the anchor tool placed at that location. Multiple anchor tools may be employed if it is desired to deploy the tool string at different levels. All operation of the anchor positioner is effected by mechanical force.
