Zero Degree Phasing
On Episode 8 of TejanoBrown on the Ground our wireline expert is showing us how zero degree phasing works.
What is perforation phasing?
The radial distribution of successive perforating charges around the gun axis. Perforating gun assemblies are commonly available in 0-, 180-, 120-, 90- and 60-degree phasing. The 0-degree phasing is generally used only in small outside-diameter guns, while 60, 90 and 120 degree phase guns are generally larger but provide more efficient flow characteristics near the wellbore.
