Linepack in the distribution area

market region:

The quantity of natural gas contained in a pipeline is referred to as “linepack”. This is calculated by multiplying the geometrical pipeline volume by the compressibility factor (Z-factor). The Z-factor depends on the absolute pipeline pressure, gas temperature and gas composition. If injection into the distribution area does not precisely match withdrawals from it – as is normally the case – the contents of the pipeline, or linepack, are bound to change.
