Select an AGA8 Method
AGA8 is used for calculating compressibility factors of natural gas and other
related hydrocarbon gases.
There are three AGA8 methods:
• Gas analysis
This is the Detail Characterization Method in AGA8 standard. This
method applies a detailed knowledge of the mole fractions of up to 21
components of natural gas.
• HV-GR-CO2
This is the Gross Characterization Method 1 in AGA8 standard. This
method uses heating value, relative density, and carbon dioxide content
as inputs.
• GR-CO2-N2
This is the Gross Characterization Method 2 in AGA8 standard. This
method uses relative density, carbon dioxide content, and nitrogen
content as inputs.
Select one of these methods according to the known conditions in the field
and click Download to apply the settings to the DataSite controller.
