The EZReporter Natural Gas Liquids (NGL) Module is designed to perform standard Natural Gas Liquids extended analysis and reporting based on the GPA 2186/2286-02 and GPA 2186/2286-14 (and related) standards. The results from these calculations are available for reporting, monitoring, trend plotting, and exporting.
Overview
The EZReporter Natural Gas Liquids (NGL) Module is designed to perform standard Natural Gas Liquids extended analysis and reporting based on the GPA 2186/2286-02 and GPA 2186/2286-14 (and related) standards. The results from these calculations are available for reporting, monitoring, trend plotting, and exporting.
The EZReporter 4.0 Natural Gas Liquids Edition also includes a license for the Natural Gas Analysis module.

Extended Fraction Calculation Methods
There are several different methods defined in the GPA 2186-02 and GPA 2186-14 standards to calculate extended (Hexanes Plus) analysis results. EZReporter 4.0 supports the following calculation methods:
- Separate: The TCD and FID extended analysis results are each calculated and reported separately. The TCD results, including C6+, are used to generate the total sample results, while the FID results are used to generate the average extended fraction results.
- Combined/Bridging: The TCD and FID extended analysis results are combined into a common report with the option of applying “bridge” factors to normalize the relative response from each detector. The C6+ results in the total sample report are derived from the individual combined FID extended component calculated results.
- Allocation: The individual FID extended component amounts are first adjusted so that the total FID C6+ amount is equal to the total TCD C6+ amount. The C6+ results in the total sample report are then derived from the individual combined FID extended component calculated results.
Standard Component Data Sources
EZReporter 4.0 includes component physical property constants from the following standard data sources that can be used in the NGL calculations:
- GPA 2145-16
- GPA 2145-09
- GPA 2145-03
- GPSA Engineering Data Book
- GPA TP-17
- ASTM D3588-98 (2003)
- ASTM D2598-02 (2007)
- ISO 6976
- ISO 8973 (1977)
In addition, the component constants can be edited manually to use constants from other data sources.
Calculated Results
The following “average” results are calculated for the extended fraction:
- Gross Heating Value (BTU / ideal cu. ft.)
- Gross Heating Value (BTU / lbm)
- Gross Heating Value (BTU / gal.)
- Average Molecular Weight
- Vapor Pressure (psia or psig)
- Liquid Density (lbm / gal. and lbm / bbl)
- Relative Liquid Density
- Gas Density (lbm / cu.ft.)
- Volume (cu.ft. / gal.)
- API Gravity
