When one considers probabilistic summation of multiple wells or zones, the more chances at a discovery (i.e. multiple wells), the higher the chance one zone will contain hydrocarbons.
And I am not anti-HDYN. What I do question is some on this board who are making calculations of value before a discovery well is drilled. I have seen this numerous times in my 35+ years in Exploration, people are counting barrels and calculating cash flow and whatnot and are then deflated when the well is not a discovery. This is exactly why the SEC will not allow companies to book reserves pre-drill. Calculating pre-drill resource volumes is fine but not reserves and certainly not booked as assets.
And if one wants to see an anti-HDYN bias, please go to the Yahoo board for HDYN and see what marc.gerade (allegedly James Spear) posts over there. He is a one-man anti-HDYN juggernaut.
