Abstract
A downhole perforation tool includes an upper sub-assembly configured to couple to a downhole conveyance within a wellbore that is formed from a terranean surface toward a subterranean formation; and a plurality of perforation sub-assemblies. Each perforation sub-assembly includes one or more perforation guns, and one or more ports configured to fluidly couple the wellbore with a bore that extends from the one or more ports to the upper sub-assembly. The downhole perforation tool further includes a main wellbore seal positioned between the upper sub-assembly and the plurality of perforation sub-assemblies and actuatable to anchor the downhole perforation tool to a casing in the wellbore. The downhole perforation tool further includes at least one secondary wellbore seal positioned between adjacent perforation sub-assemblies of the plurality of perforation sub-assemblies. The at least one secondary wellbore seal is actuatable to fluidly isolate a portion of an annulus of the wellbore from another portion of the annulus of the wellbore.
