Analyzing Natural Gas Composition

COURSE NO: P02-005
Analyzing Natural Gas Composition
Course Highlights

This online engineering PDH course provides information on how to analyze natural gas composition data to determine specific gravity, molecular weight, critical temperature, critical pressure, heating content, liquid yield, and shrinkage.


Due to the structure of its hydrocarbon components, natural gas deviates from the Ideal Gas Law and must be modified using the gas compressibility factor. Additionally, as natural gas is brought to the surface, certain components may liquify and cause operational issues. The properties determined from the analysis of natural gas composition are needed for calculation of the gas compressibility factor, behavior of gas at reservoir and surface flow rates, the estimation of condensate and natural gas liquid yields, and gas processing requirements.


This 2 PDH online course is applicable to petroleum, chemical, and geological engineers who are involved with the production and distribution of natural gas and natural gas liquids.
