Ann: Highest Waitsia flow rate to date - 90 MMscf/d at Waitsia-4, page-25

Palm Valley produced something like 160 bcf from memory. It's still in operation today (currently shut in I believe) but only capable of a few TJ/d. Once the fractures were empty the actual matrix permeability is very low and not capable of sustaining high rates.

Waitsia is a very different reservoir and it's not a risk that they have just hit a sweet spot - they've drilled five wells including Senecio 3 and all of them have had flow rates above 10 MMscfd. At Waitsia the actual matrix permeability is extremely high for such a deep reservoir, which seems to be due to an unusual diagenetic effect such as clays coating the grains and preventing secondary overgrowth. Combined with that, the reservoir is very thick.
