Although turbulence can account for 90% of the pressure drop for gas flowing through casing perforations, recent studies indicate that flow through the damaged compacted zone around each perforation is especially important. This article presents the results of a computer model study which outposts the effect of damaged compacted-zone permeability on gas productivity, and selection of perforation shot density for a high-flowrate well. The analysis may be useful to the completion engineer in determining the most appropriate perforation technique and shot density.
