Hydrodynamic down-hole anchors and related methods

Abstract

Tubing anchor catchers that include a mandrel having a first end portion and a second end portion, each end portion having threading with multiple starts, a first cone, a second cone, and a slip that is at least partially disposed between the first cone and the second cone. The first cone and second cone are coupled to the mandrel via the threading with multiple starts such that when the mandrel is rotated in a first direction with respect to at least one of the first cone and the second cone, the at least one of the first cone and the second cone is configured to move to reduce a distance between the first cone and the second cone to force the slip to move laterally from the tubing anchor catcher. Furthermore, the slip engages with a well bore or casing following between less than six rotations of the mandrel.

Dependencies are inferred from the claim text.
