Abstract
A process for manufacturing a perforation gun casing includes providing a perforation gun housing that has a wall of nominal thickness and at least one scallop. Each scallop is a portion of the wall having a reduced thickness relative to the nominal wall thickness. The process also includes applying a selective annealing process to the perforation gun casing. The selective annealing process affects the material properties of the scallop but generally does not substantially affect the material properties of the portions of the wall having a nominal thickness.
