Bigshot 21 gravel-pack gun.

Bigshot 21 Big Casing Entrance Hole Perforating GunsMaximizing the area open to flow

Bigshot 21* perforating gun systems are loaded with big hole shaped charges and configured to produce large-diameter perforations. Maximizing the area open to flow (AOF) of the perforations is typically used in sand control completions to facilitate placement of the gravel pack.

The mechanical specifications for the various Bigshot 21 guns are the same as those for corresponding HSD* High Shot Density perforating gun systems.
