GENERAL TERMS AND CONDITIONS

 

 

4. MEASUREMENT REPORTING (Continued)

 

4.1 Physical Volume (Continued)

 

4.14 Data Elements

 

Company and its trading partners shall accept all

standard measurement data elements as specified by

NAESB WGQ and adopted by FERC. Such data elements

and their usage are detailed in Section 35 of the

General Terms and Conditions.

 

4.15 Metric Conversion for Volumes

 

The Metric reporting unit for natural gas volume is

thousands of cubic meters (10E3 M3) at standard

reference temperature and pressure conditions of

15 degrees C and an absolute pressure of 101.325 kPa

respectively. The conversion factor to convert

cubic feet (at Standard Reference Conditions) to

cubic meters is:

 

(cubic feet) X 0.02832784 = (cubic meters)

 

4.16 Supercompressibility

 

Measured gas volumes shall be corrected for

supercompressibility (deviation of the gas from the

laws of ideal gases) at the pressures and

temperatures at which the gas is measured. Except

as otherwise agreed by Company and Shippers, the

factors for such corrections shall be obtained from

data contained in the A.G.A. Manual for the

Determination of Supercompressibility Factors for

Natural Gas developed under P.A.R. Research Project

NX-19 completed in December 1962, or any subsequent

revision or replacement thereof.
