Perforating methods and devices for high wellbore pressure applications

A carrier tube for a wellbore perforating gun, comprising:

• a porous tubular core;
• at least one shaped charge positioned inside the tubular core;
• a fluid impermeable retention element surrounding the tubular core, wherein the retention element is configured to transfer compressive forces applied by a wellbore fluid pressure external to the carrier tube to the tubular core;
• and wherein the retention element contains at least one fragment of the tubular core after a detonation of at least one shaped charge inside the tubular core;
• and
• at least two adjacent components of the perforating gun coupled to one another by the retention element.

A method for perforating a wellbore in a relatively high pressure wellbore environment using a wellbore perforating gun, comprising:

• positioning at least one shaped charge of the wellbore perforating gun in a porous tubular core;
• and
• surrounding and sealing tubular core with a fluid impermeable retention element;
• transferring substantially all of the compressive forces applied by a wellbore fluid pressure external to the carrier tube to the tubular core using the retention element;
• containing within the retention element at least one fragment of the tubular core after the detonation of the at least one shaped charge;
• and
• connecting an upper component of the perforating gun to a lower component of the perforating gun using the retention element after detonating the at least one shaped charge.
