All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A perforation gun string for use in perforating a wellbore, comprising:
a perforation gun, wherein the perforation gun forms at least a part of the perforation gun string; and
sections of a swellable material coupled to and spatially located around the perforation gun string, wherein the sections of the swellable material are configured to be exposed to a downhole wellbore environment and to swell and protrude beyond an outer surface of the perforation string in response to exposure to the downhole wellbore environment, and wherein the sections of the swellable material are spatially arranged to form one or more longitudinal fluid gaps between adjacent sections of the swellable material, the gaps being configured to allow fluid flow therebetween.
2. The perforation gun string of claim 1, further comprising a tandem coupled to the perforation gun, wherein the sections of the swellable material are coupled to the tandem.
3. The perforation gun string of claim 1, wherein the sections of the swellable material are coupled to the perforation gun.
4. The perforation gun string of claim 1, further comprising a subassembly coupled to the perforation gun, wherein the sections of the swellable material are coupled to the subassembly.
5. The perforation gun string of claim 1, wherein the sections of the swellable material comprises one of low acrylic-nitrile, ethylene propylene diene rubber, or a cross-linked polyacrylamide.
6. The perforation gun string of claim 1, wherein the sections of the swellable material are coupled to the perforation gun string in cavities of the perforation gun string.
7. A downhole tool, comprising:
a tandem for use in making up a perforation gun; and
sections of a swellable material coupled to the tandem, wherein the sections of the swellable material are configured to swell in response to being exposed to a downhole wellbore environment, wherein the sections of the swellable material are configured to permit fluid flow between an annular region above the sections of the swellable material and an annular region below the sections of the swellable material after the sections of the swellable material swell, and wherein the sections of the swellable material are spatially arranged to form one or more longitudinal fluid gaps between adjacent sections of the swellable material.
8. The downhole tool of claim 7, wherein the tandem comprises a surface cavity and the sections of the swellable material are retained within the surface cavity.
9. The downhole tool of claim 7, wherein the sections of the swellable material comprise a plurality of separate pieces, and wherein each piece of swellable material is retained within a corresponding surface cavity of the tandem.
