40 Percent of Countries with Largest Shale Deposits Face Water Stress

World Resources Institute

Right now, dozens of countries around the world are deciding whether or not to develop their shale gas and tight oil resources (tight oil deposits are trapped in fine-grained sedimentary rock, including shale). It’s easy to understand why: shale gas could boost the world’s recoverable natural gas resources by 47 percent, cut greenhouse gas emissions compared to coal, create new revenue and jobs, and raise national energy supplies.

However, extracting natural gas and tight oil from shale poses environmental risks, especially when it comes to water. Hydraulic fracturing requires up to 25 million liters of fresh water per well, meaning shale resources can be hard to develop where fresh water is hard to find—including in some of the world’s fastest-growing economies and populations.
