I think GL expressly addressed the negative posters by delivering some accurate guidance on how to interpret the figures ex NG Data Viewer.
Very good of him to sift through the posts on here.
Explanation of Terminology:
Kwhr, Therms, megajoules (MJ) are all measures of the energy content of a quantity of gas and have a fixed and unvarying relationship with one another.
scm (standard cubic metre) mscm (thousand standard cubic metre) and mmscf (million standard cubic feet) are traditional measures of volumes of gas. As producers we tend to observe volume flow from wells and through process plant but we are paid on the energy content which is metered and analysed at point of sale.
These two types of measurement, energy and volume, are related by the calorific or higher heating value which is the number of MJ per standard cubic metre. Very intense processing, i.e. lower temperatures, will tend to remove more higher hydrocarbon fractions such as propane, butane and pentane, which will lower the calorific value but improve the margin of safety in terms of meeting transmission grid specification.
