10. A perforation tool, comprising:
a tubular housing;
an initiation module disposed within the tubular housing, the initiation module comprising a detonator housing protruding from an end of the initiation module for housing a detonator; and
a charge canister disposed within the tubular housing, the charge canister comprising:
a cylindrical body having an expansion portion extending along a radius of the cylindrical body, the expansion portion having a randomized textured interior surface, a narrow portion at a first end of the expansion portion and a wide portion at a second end of the expansion portion opposite from the first end; and
an explosive material disposed within the expansion portion in direct contact with the randomized textured interior surface of the expansion portion.

19. A method of making a charge canister for a perforation tool, the method comprising:
applying a randomized surface preparation to an interior surface of an expansion portion of a cylindrical body, wherein the randomized surface preparation comprises texturing the interior surface to provide a randomized textured interior surface prior to disposing an explosive material into the expansion portion;
disposing the explosive material into the expansion portion of the cylindrical body, the cylindrical body having the expansion portion extending along a radius of the cylindrical body, the expansion portion having a narrow portion at a first end of the expansion portion and a wide portion at a second end of the expansion portion opposite from the first end, the explosive material in direct contact with the randomized textured interior surface of the expansion portion;
disposing a liner against the explosive material within the expansion portion; and
pressing the liner against the explosive material to set the explosive material and the liner into the expansion portion.
