So the new ANH contract announcement (to be followed by another...) confirms - to anyone bovvered to read it and think about what it says - that it has a number of old Ecopetrol (probably) wells on it, and it's a proven reservoir (and knowing Ecopetrol, they'll already have an estimate for what it might contain). Interesting.
btw, why don't the big boys buy more EEN? Well, where would they come from? They could only do so by forcing the price up. And I can't see that releasing many EEN, unless the rise was big, after all, Evo say Tigris could be worth an extra £12 a share if the Ryder Scott total is confirmed. And who knows? The big boys get special briefing from Emerald, and they might be constrained from buying because of that.
