GENERAL TERMS AND CONDITIONS
3.7 The unit of volume "at 1,000 Btu per cubic foot" or "as adjusted to
1,000 Btu per cubic foot" shall mean one cubic foot of gas as defined above
and having an average total heating value of one thousand (1,000) British
Thermal Units. Such units of volume shall be determined by multiplying the
number of cubic feet of gas delivered during any billing day by the factor
arrived at by dividing the average total heating value per cubic foot
delivered on the previous day by 1,000 unless otherwise agreed to by WTG
3.8 Supercompressibility. Determination of supercompressibility of natural
gas shall be calculated from chromatographic analysis of gas samples taken at
representative points as determined by WTG Hugoton.
3.9 Gas Sampling and Analysis. Gas samples may be obtained and analyzed by
one of the following methods:
(a) Portable Chromatograph. Chromatographic analysis of a spot sample
of gas taken at a representative location and analyzed on site by means of a
portable gas chromatograph.
(b) Spot Sample. Spot sample of gas taken at a representative location
using a sample bottle and analyzed using a gas chromatograph at a location
remote from the sampling location.
(c) Continuous Sample. Sampling continuously into a sample bottle for
a period of time at a representative location and then analyzing the sample
using a gas chromatograph.
(d) On-Site Gas Chromatograph. On-site chromatograph sampling directly
from a representative source and analyzing continuously.
(e) System Gas Chromatograph. Gas chromatograph sampling directly from
a representative source and analyzing continuously. The results are then
applied to all other locations on the system that are representative of the
Spot Sampling Frequency. Mutually agreed upon frequency (monthly, quarterly,
