Pottermore (and others) - this may or may not help you.

FWIW here's a few pics which (hopefully are readable and give a better idea about the potential of the Caryginia formation - I've ignored the other 2 formations for now - in EP413).

Quite a few gaps still there but shale gas potential still looking good to me.

Also some really good material here:
