An anchor and a method for limiting the movement of a tubing string within a wellbore are provided. The anchor comprises a mandrel, a slip body assembly, a drag block assembly, and a mechanism for transitioning the anchor between a release position and a set position. The mechanism is operable by relative movement between the drag block assembly and the mandrel. The anchor is transitionable between the release position and the set position by rotating the mandrel less than half a full turn relative to the drag block assembly. |
