David, You are probably right on those figures and we cracked some a few months ago..
But..
I got a feeling that this is not going to be a "one show pony".. As has been stated a number of times.
PROOF OF CONCEPT - through drilling and testing phase of this Arrowsmith formation of Shale.
Have a read of this 1994 report and you might get an idea of how big this "Could be"..
I could also be very wrong in my assumptions but at this stage I will go with AWE, Indians and NWE team and say there could be a lot more to this story that we Plebs are hearing.
Read from about page 16-28.. This well that NWE and team are doing could be only the start of a HUGE opening up of this formation Shale..Take a note of the scale metric's on page 22
