Costs are coming down as China’s fledgling shale industry gets its feet underneath it—but there’s still a long way to go.

Argentina boasts the world’s second and fourth largest shale gas and tight oil reserves, respectively, and by passing an oil and gas reform law earlier this week, it hopes to catch up to the American shale revolution.

A new report finds that more than a third of the world’s shale gas reserves lie in relatively arid regions, which helps explain why so many countries have failed to replicate America’s fracking success.

Britain is issuing new licenses for oil and gas drilling for the first time in six years. The country won’t find replicating U.S. shale success simple or easy, but this latest move is a step in the right direction.
