re: **comment you should read ** I think that "not" might be a typo and should read "note".
Anyway it's the Monteray that's the big prize (100 mn barrels, which is US$5bn worth of revenue at todays prices). The shallow gas, which I believe is very significant, represents a smaller portion of the value.
everyone should make their own mind up whether they want to play this or not. Don't trust me, trust your own judgement.
