KF requires fracking. Therefore it is not conventional.
This is nonsense. Plenty of conventional wells are fracced, and have been for the last 40 years. Clearly just because something requires fraccing doesn't make it unconventional.
Kingfisher is a conventional gas accumulation because the gas migrated from a source rock into a trap with structural closure.
It's just a tight conventional gas accumulation.
Your link from the CSIRO just reinforces what I said. It says: Unconventional gas is generally produced from complex geological systems that prevent or significantly limit the migration of gas.
Kingfisher gas migrated to the sandstone from a source rock where it was trapped by structural closure. It was not "prevented or significantly limited." Therefore it is conventional gas.
In CSG, shale gas and 'tight gas' (meaning basin-centred gas accumulations) the gas is held in place by other means, not structural or stratigraphic closure.
So Kingfisher is, technically, a tight conventional gas resource that will require unconventional drilling techniques to extract economically. MEL is well within their rights to refer to Kingfisher as conventional gas.
