3. MEASUREMENT

 

3.1 Unit of Volume:

 

The unit of volume shall be a cubic foot.

 

3.2 Measurement of Volume:

 

(a) When gas is delivered at a pressure different from

14.73 psia, then for the purpose of measurement

hereunder, such volumes of gas shall be corrected to

a pressure of 14.73 psia. The measurement of gas

volumes shall be adjusted for deviation from Boyle's

Law in accordance with generally accepted

engineering practice. For reporting and calculation

purposes, the factor used to correct to the pressure

base of 14.73 psia shall be stated to at least the

sixth decimal place.

 

(b) Where orifice meters are used, volumes delivered

shall be computed in accordance with formulae,

tables and methods prescribed in Orifice Metering of

natural gas and other related hydrocarbons fluids,

AGA Report No. 3 - ANSI/API 2530, as revised

September 1985, and as such report may hereafter be

further revised (i.e. AGA Report No. 3, 1992 Edition

and AGA Report No. 8), or other formulae, tables and

methods acceptable to the Minerals Management

Service. Exact measurements of inside diameters of

meter tubes shall be obtained by means of micrometer

to the nearest one-thousandth inch. The standard

for Electronic Gas Measurement shall be API Chapter

21.1. Said volumes shall be corrected for flowing

temperature and specific gravity in accordance with

the provisions of Subsections 3.2(c) and 3.2(d)

below.

 

(c) The flowing temperature of the gas shall be

determined for the purpose of measured volume

correction. Volume shall be corrected for each

degree of variation in the flowing temperature from

60 degrees Fahrenheit. The flowing temperature will

be measured by the continuous use of temperature

transducers, and shall be either (1) recorded using

digital recorders, or other mutually agreeable
