Sorry Brick,
Read the announcement and then read up on the 'P's.
P1 = P90 = Discovered 15bcf + Undiscovered 12.3bcf
Ya has written P1 = 418.4bcf for Disc + Undisc, which is wrong.
418.4 bcf is a P3 NOT P1
That why people pay for P1 and P2 reserves, because P3 is not an accurate indication of reserves, and the reason is that the 3rd 'P' stands for Possible.
P1 and P2 stand for Proven and Probable.
Hop
