Sorry folks, I have just spotted an error in the table of volumes I posted earlier today....
The Best PR estimate has now been corrected, which appears to be the same as the Mean PR estimate (36 Tscf).
Rather than assume the Low Case is to 3700m MD,Best Case to 4000m MD and High Case to 4500m MD, I have decided to re-calculatethe volumes assuming a consistent depth, i.e. gas is expected down to the baseof the Lower Angwa at 4500m MD (fill to spill).
That means the approx PR volumes come to:
Min = 21 Tscf
Best = 36 Tscf
High = 51 Tscf
Mean = 36 Tscf (or 30 - 33 Tscf plus 0.5 - 1.0 bn stb oil in the Upper Angwa).
