Carbon storage: Overrated, unlikely

And, that not some environmentalist challenging ExxonMobil, Massey Coal, etc., in touting the worth of carbon capture and storage. It's renowned oilfield economist Michael Economides.

What's the problem? Pressure build-up with storage attempts:
"It is like putting a bicycle pump up against a wall. It would be hard to inject CO2 into a closed system without eventually producing so much pressure that it fractured the rock and allowed the carbon to migrate to other zones and possibly escape to the surface," Economides said.
ExxonMobil and Massey, via the American Petroleum Institute, are already trying to shoot down Economides' paper, and he's already fired back.
