(87 x 170 - 100 x 140) / 30

=26 AUD / boe x 30k boe =
$0.8M for the quarter
But rate is now 2.7TJ/day and set to keep increasing in line with P50 curve.

26AUD per boe = 26 x 0.16 = $4.16/GJ which is what you would expect.

So seems totally reasonable to me.

At 2.7TJ we are getting $1.0M per qtr = $4.0M per year.

But look back at the @RollerCoaster's post of the P50 gas curve (as disclosed by SXY). It peaks much higher, so this should only increase from here
