Bloomberg has cool graphic showing shale-oil break-even points

With the global plunge in oil prices comes concern that many U.S. companies that drill in tight-oil shale formations might be hurt, since it’s more expensive to extract that oil and their profit margins are smaller.

But Bloomberg has a helpful chart showing that “most regions continue to be profitable below $80, including the Bakken and Eagle Ford formations, two of the most important sources. Much of the Eagle Ford play would still be profitable with $50 oil.”
