Seriously, I wonder why that stuff isn't being explored as at the very least a very cheap natual gas supply? It would be better to burn it rather than it allowed to go to waste bubbling up and being released naturaly into the atmosphere.
I can only guess that it's being saved for "discovery" at a later time once big oil has extracted all they can from oil.
