Typing natural gas pipeline specification into Google led me to this interesting paper - see Page 4 http://www.beg.utexas.edu/energyecon/lng/documents/CEE_Interstate_Natura...

It mentions gas turbines as one end use that is sensitive to changes in fuel specification, for example with LNG. This is because GT burners run a lot hotter and therefore nearer to the thermal creep limit than most end uses of natural gas.

Natural gas, being a natural product, has a variety of compositions.

Mostly it is methane (CH4) but can have various amounts of propane, butane, and ethane (2CH3 + XCh2) plus non-combustibles like N2, CO2, and He that cost various amounts to remove.

Trying to meet market specifications can doom a gas field economically. Nitrogen is especially expensive to remove with little co-product value, unlike helium.
