Abstract
A self-positioning system for a perforating gun or gun string is provided. The self-positioning system includes a plurality of protrusions extending outwardly from the perforating gun or the gun string for providing a finite number of rotational positions and/or for providing a desired water clearance. The protrusions include one or more groupings of at least three protrusions, the protrusions being angularly offset from each other about the outer circumference of the perforating gun or gun string.
