In contrast, gas extractions occur because the consumption sites along the pipeline use gas under lower pressure conditions than those present in the section of the transportation system where they are interconnected.

The objective of a pipeline transmission system operator such as Cenagas is to ensure that pressure differentials cause flows in the right...
