A method of perforating and gravel packing a wellbore casing, having the following steps: (1) making-up to a pipe string: a packer, a screen, and a perforating apparatus; (2) running-in the pipe string until the perforating apparatus is at a depth of intended perforations; (3) setting the perforating apparatus in the wellbore casing at a depth of intended perforations; and (4) disconnecting the screen and perforating apparatus from the pipe string. A system for perforating and gravel packing a wellbore casing, having: a packer which is mechanically communicable with a service string: a screen in mechanical communication with the packer; a perforating apparatus in mechanical communication with the screen, wherein the screen and perforating apparatus are detachable from the packer; and a tool having at least one casing engaging slip segment, wherein the tool is matable with the perforating apparatus, and wherein the tool is settable in the wellbore casing.

Rigless one-trip perforation and gravel pack system and method

A system and method for perforating and gravel packing a wellbore casing in a single trip into the wellbore comprising a gravel packer assembly having a production screen and at least one packer. A perforating apparatus connected to the gravel packer assembly, wherein the perforating apparatus is detachable from the gravel packer assembly after the system is placed in the wellbore and before a detonation of the perforating apparatus. A tool having at least one casing engaging slip segment, wherein the tool is matable with the perforating apparatus and is settable in the wellbore casing.
