Abstract
A perforating system having a perforating gun with a high pressure gun body. The gun body can be thickened so that no empty space is present between it and a corresponding gun tube. Alternatively, the gun body could be a solid cylinder with slots radially formed therein to receive a shaped charge. In another embodiment, a flowable material, such as foam, fluid, sand, ceramic beads, eutectic metal, and combinations thereof, is provided in the space between the gun body and gun tube.
