All over the world. Lots of it. As with US shale, estimates of proved reserves are all over the map -- ranging from as low as 10 years' worth to as high as several centuries' worth.
While Chesapeake Energy has long disclosed that Norwegian geologists and engineers are studying shale at the Oklahoma City producer's shale school (also in Oklahoma City) as part of Statoil's $3.4 billion buy into one-third of Chesapeake's Marcellus play, the Times' Sunday piece lifted a few other small kimonos:
ExxonMobil has drilled some exploratory shale wells in Germany, Chesapeake's rival shale cracker Devon Energy is teaming up with French oil giant Total to drill horizontal wells in France, and ConocoPhillips has signed a deal to bring the magic of hydraulic fracturing to Poland.
Italian oil company ENI bought a small shale field north of Fort Worth in May from Quicksilver Resources and is using it to educate its engineers and scientists while Quicksilver workers operate the field.
