What I do know is Bow Energy got $1.52 from Arrow in 2011 for:
2P =238PJ 3P=2752PJ 3C=2521PJ
Blue has got 2P=71PJ 3P=298PJ 3C=3942PJ
You have to throw in the high gas demand at this time as a factor to value Blues' gas, but it's fair to say they are sitting on a huge uncontracted contingent resource.
Pity they sat on their hands for years when they could have been proving up reserves.
