gas pipe line, page-48

Excuse me Occam? You patronise me?
I can name a few tight gas plays in Australia, so you'd better do your research if you think there are none.

And for your information, tight gas refers to natural gas produced from reservoirs that have very low porosities and permeabilities.
Reservoirs are usually sandstones, although carbonate rocks can also be tight-gas producers.
The standard industry definition for a tight-gas reservoir is a rock with matrix porosities of 10% or less and permeabilities of 0.1 millidarcy (mD) or less, exclusive of fracture permeability. Many “ultra-tight” gas reservoirs have in situ permeabilities as low as 0.001 mD.


I wont list them you will have to do your own research.
