Full bore automatic gun release module

#1. Field of the Invention

#The present invention relates to the art of well drilling and earth boring. More particularly, the invention relates to methods and apparatus for perforating wellbore casing, casing liner and/or fracturing well production zones.

#2. Description of Related Art

#For a thorough understanding of the present invention, reference is made to the following detailed description of the preferred embodiments, taken in conjunction with the accompanying drawings in which like reference characters designate like or similar elements throughout the several figures of the drawing. Briefly:

#FIG. 1 is a downhole schematic of the invention.

#FIG. 2 is a quarter section view of the invention assembly set for in-running down a work string tube at the end of a wireline.

#Construction and Assembly

#The invention is shown schematically by FIG. 1 to include production tubing 10 suspended within a wellbore 11. The production tubing may be secured to the wellbore wall by anchoring slip elements of a production packer joint 13. An annular space between the packer joint outer perimeter and the inside wellbore wall is bridged by expansible packer seal elements 15. This bridge across the wellbore annular space isolates the well production zone below the packer joint 13 from the wellbore space above the packer joint 13.

#Although the invention operating environment may include substantially horizontal wellbore orientation, references herein to “upper” and “lower” are generally related to the wellbore surface direction. Accordingly, the left end of the FIG. 2 through 10 illustrations normally represents the “upper” end direction of the assembly. Descriptive references to “up” and “down” hereafter will be consistent with this orientation.
