Original Sheet No. 14 Original Sheet No. 14 : Effective
nitrogen mole fraction values for the gas delivered or
received as may be required to compute such adjustments in
accordance with standard testing procedures. At Caprock's
option, equations for the calculation of supercompressibility
may be taken from either the AGA Manual for the Determination
of Supercompressibility Factors for Natural Gas, dated
December 1962 (also known as the "NX-19 Manual") or AGA Report
No. 8, dated December 1985, Compressibility and
Supercompressibility for Natural Gas and Other Hydrocarbon
Gases, latest revision.
(I) Assumed Atmospheric Pressure: An assumed
atmospheric pressure as defined in the Agreement for the
respective Delivery and Redelivery Point(s) shall be utilized
for measurement and calculation purposes, irrespective of any
variation of the actual atmospheric pressure from the assumed
atmospheric pressure.
(J) Gross Heating Value: At least quarterly the Gross
Heating Value of the gas delivered at the Redelivery Point
hereunder shall be determined by calculating the Gross Heating
Value from an on-line chromatographic or a gas analysis of a
spot or continuous gas sample. The spot or continuous sample
shall be taken at least quarterly and such sample shall be
taken at a suitable point on the facilities to be
representative of the gas being metered.
(K) Other Tests: Other tests to determine water
content, sulfur, and other impurities in the gas shall be
conducted by Caprock as necessary and shall be conducted in
accordance with standard industry testing procedures. The
party requested to perform such test(s) shall bear the cost of
test(s) only in the event the gas tested is determined not to
be within the applicable specification(s), otherwise the
requesting party shall bear the cost of such test(s).
(L) New Test Methods: If at any time during the term
hereof a new method or technique is developed with respect to
gas measurement, such new method or technique may be
substituted for the method set forth in this Article when such
methods or techniques are in accordance with the currently
accepted standards of the American Gas Association, if
mutually agreed upon by the parties.
4.13 Right of Inspection: Caprock or Shipper shall have the
right to inspect equipment installed or furnished by the other or
third party operators and the charts and other measurement or
testing data of all such parties at all times during business hours;
but the reading, calibration and adjustment of such equipment and
changing of charts shall be done by Caprock, or its designee, unless
agreed to otherwise by the parties.
