PC43,

Thanks for that info. However I have another question this time on Nitrogen in a gas reservoir.

Does it have a commercial application (whether it be fertilizer production or otherwise) when its in this form, or is just considered an uneconomic impurity?

Just as an example here is the Meda-1 gas analysis, do you think its on the ugly side of acceptable?

From page 30 of the Australian Petroleum Accumulation Report 9, Canning Basin, WA.
