There is an article in this weeks MoneyWeek regarding 'Coal Bed Methane".

"Merrill Lynch estimates that there are 30 trillion cubic metres of methane -the equivalent of 1.35 billion barrels of oil -trapped in China's coal seams"

How does CBM fit in? Is it classed as an NGL?

Nick.

CBM (Coal Bed Methane) is to my best understanding pure methane (CH4) which is not classified as NGL.

Methane could be used as feed for LNG (Liquefied Natural Gas) or for GTL (Gas To Liquids; Fischer-Tropsch) process. In Fischer-Tropsch the output is 60 – 70 % of what is fed into the process.
