Standing and Katz gas compressibility factor
gas compressibility factor is the ratio of the Real Gas volume to the Ideal Gas volume, which is a measure of the amount that the gas deviates from the perfect behavior.
Discussion
Dranchuk correlation is the default correlation for the gas compressibility factor in the PVT tool.
