19. MEASUREMENTS AND TESTS FOR DELIVERY OF NATURAL GAS (Continued)

(h) Supercompressibility.

(1) The deviation of the Natural Gas from the Ideal Gas Laws shall be determined:

(i) in accordance with the American Gas Association, Par Research Project NX-

19 report, titled "Manual for the Determination of Supercompressibility

Factors for Natural Gas", Reprinted 1976, if the composition of the

natural gas is such to render this procedure applicable, or

(ii) by any other method mutually agreed upon by Operator and Buyer.

(2) If the measurement method used by Operator requires the concentrations of

nitrogen and carbon dioxide, the concentrations of nitrogen and carbon dioxide

shall be determined by chromatographic or other generally accepted analytical

method at Operator's option:

(i) where Electronic Measurement equipment is provided,

(a) by contemporaneous application of continuous instantaneous

measurements of the concentrations of nitrogen and carbon dioxide,

or by contemporaneous application of the arithmetic or other average

of the concentrations of nitrogen and carbon dioxide for the time

during which gas was flowing,

(b) by prospective application of the arithmetic or other average of the

concentrations of nitrogen and carbon dioxide record, or

the gas; or

(ii) where Electronic Measurement equipment is not provided,

(a) by the contemporaneous application of the arithmetic or other

average of the hourly or daily concentrations of nitrogen and carbon

dioxide, or

(b) by prospective application of the results of analyses of samples of

the gas; or

(3) by any other method or methods mutually agreed upon by Buyer and Operator.

(i) Measuring Equipment.

(1) Unless otherwise agreed to in writing, Operator shall install, operate, and

maintain measuring stations and equipment by which the quantities of Natural Gas

delivered by Operator are determined.
