OK, if you insist.
Here's how it's going to be produced: With oil wells. Just like this one, from the Falcon Oil and Gas PDF linked above.
As for the cost, according to the PDF, Falcon says it has 7 million acres leased in the Beetaloo Basin. Let's say only half of those get developed - maybe the other half are geologically bad spots, environmentally off-limits, or other reasons. So we've got 3.5 million acres to deal with.
Spacing for wells like this are usually 1 per square mile (640 acres) or sometimes 2 or 4 per square mile, depending on how good the rock it's tapping into is at that location. Uniform 1 square mile spacing would get you 5,468 wells. Let's say they develop some of it in 2 or 4 per sq mi spacing, so let's round that up to 6,000 wells.
Wells drilling into this thing are going to be similar to Bakken wells, which typically run around $5 million each (USD). Assuming costs in this part of Australia would be reasonably similar (who knows?), 6,000 wells would cost a total of $30 billion. Of course that would be stretched out over 20 years or thereabouts. Add in another, say, $5 or $10 billion for various kinds of infrastructure (pipelines, etc) and you're at $35-$40 billion. There are also costs for leases (probably just a handful of owners in this case), royalties and a few other things. So let's just round it all up to an even $50 billion.
The PDF outlines many similarities of this shale to the Bakken. Wells in the Bakken these days have EUR's of around 500K-700K barrels. Let's use an average of 600K.
600K barrels/well x 6,000 wells = 3.6 billion barrels produced. Notice this is a conservative number, as the
link I posted above states a mean recoverable value of 17.5 billion barrels.
Assume an average price per barrel of this particular grade of oil at $75/barrel. Multiply that by 3.6 billion barrels. You then get an income of
$270 billion from selling the oil. Compare that to the total costs I calculated above of
$50 billion. You then can see why plays like this are so lucrative.
