R649-2-8. Measurement of Production

1. The volume of oil production shall be computed in barrels of clean oil, on the basis of acceptable meter measurements, tank measurements, or with such greater accuracy as may be required by the division. Computations of the volume of oil production shall be subject to the following corrections:

1.1. The gross volume of oil shall be corrected to exclude the entire volume of impurities not constituting a natural component part of the oil.

1.2. The observed volume of oil after correction for impurities shall be further corrected to the standard volume at 60 degrees Fahrenheit, in accordance with Table 6A of the API/ASTM D-1250, Chapter 11.1, Manual of Petroleum Measurement (1980), or any revisions or supplements, or any alternative publication or tables approved by the division.

1.3. The observed gravity of oil shall be corrected to the standard API gravity at 60 degrees Fahrenheit in accordance with Table 5A of API/ASTM, D-1250, Chapter 11.1, Manual of Petroleum Measurement (1980), or any revisions or supplements, or any alternative publication or tables approved by the division.

2. All gas shall be measured by an orifice type meter unless otherwise authorized by the division.

2.1. In computing the volumes of all gas produced, sold, or injected, the standard pressure base shall be 14.73 pounds per square inch absolute (psia), and the standard temperature base shall be 60 degrees Fahrenheit.

2.2. All measurements of gas shall be adjusted by computation to these standards, regardless of the pressure and temperature at which the gas was actually measured, unless otherwise authorized by the division.
