4VAC25-150-400. Measurement of gas and oil.
A. Natural gas.
1. Each producer shall measure all gas produced from each well, or as prescribed by the director, using a method permitting the computation of volumes, in Mcf. This requirement may be met by use of the standards in:
a. "Orifice Metering of Natural Gas," ANSI/API 2530, American Gas Association, 1978;
b. "AGA Gas Measurement Manual, Part 2: Displacement Measurement," American Gas Association, 1977; or
c. "AGA Gas Measurement Manual, Part 3: Gas Turbine Metering," American Gas Association, 1989.
2. The director may require use of meters at designated places to obtain accurate records of the production of gas.
B. Oil. Each permitted oil operation shall use sufficient tanks or meters to measure the volume of oil produced. In no case shall meters be the sole means of measuring oil, unless such metering is conducted in accordance with a method approved by the director such as the API Manual of Petroleum Measurement Standards, 1981, Chapter 6.1, LACT Systems. A permittee may request a variance from the director to use a gauge tank to check the readings of meters.
