Regarding "Probable" and "Possible" reserve categories, you might place some small dollar value (few mil?) on the Probable reserves, which was < 1 mil barrels, but I have never seen any amount placed on Possible reserves when valuating a property for acquisition. Possible reserves need to be risked so heavily because so many factors (tar pricing, demand for tar, refineries able to accept it, op costs, electric prices, gas prices, daily rates, etc etc) affect its ability to be produced at all, let alone economically, it just isn't worth anything in the "real" world. Those kind of reserves are considered pie-in-the-sky. Its actually quite funny and embarrassing they would only plug in 6 mil barrels for Possible, when its so elusive and meaningless anyway they might as well made it 50 mil.
Well, Lynn said in one of his PR's that he was looking for "market place" recognition and let me tell you, it sure appears they've seen enough of his (former?) company's malarkey and sure didn't put any value on it either. But of course that's what I think....LOL
