I didn't read the linked article, but much of the natural gas around here is locked up in shale formations. The Gas producers have gotten so good at directional drilling and so efficient at extracting gas from shale, that the supply of gas has now become so abundant that they have little interest in producing it at current prices.
Many producers are selling their gas stakes ( I think an Australian firm has bought in and a China firm, and some others ) and are packing up their rigs and moving them to the oil shale formations where they think the big money is. They think they can be as successful in getting oil from shale as they have been with gas. And maybe they can.
So I wouldn't just dismiss oil shale out of hand - this oil may prove to be recoverable without a lot of hassle. If that becomes true, look for the administration to come up with a way to shut the producers down.
This area around here has so much gas I am amazed that the place does not explode when somebody tosses out a cigarette. We have lots of fossil energy on this continent - we just don't utilize it for some crazy reason(s).
