Sorry to sound a sour note here - I know how popular fracking is as an investment theme - but IMO, fracking is tomorrow's corn ethanol - yet another expensive boondoggle.
Look at the decline rates, which are much higher than with conventional extraction. What that means is you need way more wells to achieve the same output. The assumption is that higher prices will make that possible.
So, what's going to drive prices higher? Economic recovery? Global Warming? How about exports, where you're competing with long established players with much lower production costs?
I just don't see the rationale, but hey, why let a good mania go to waste?
