Dissolvable material application in perforating

A method for perforating a formation, comprising:

• lowering a perforation gun into a wellbore;
• detonating a shaped charge in the perforation gun, wherein the shaped charge comprising:
• a charge case,
• a liner,
• an explosive retained between the charge case and the liner;
• and
• a primer core disposed in a hole in the charge case and in contact with the explosive,
• wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid.

A method for perforating a formation, comprising:

• lowering a perforation gun into a wellbore, wherein the perforation gun comprises a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises the material soluble in the selected fluid;
• exposing the perforation gun to the selected fluid;
• allowing the safety valve or the firing valve to dissolve;
• establishing a pressure communication between the gun housing and the wellbore;
• and
• actuating the perforation gun.
