The U.S. is one of the largest producers of shale gas, a type of natural gas extracted from shale rock formations through hydraulic fracturing (fracking).

Shale gas has become a major part of the U.S. natural gas production due to advancements in drilling technology, particularly hydraulic fracturing and horizontal drilling. These techniques have unlocked vast reserves of natural gas trapped in shale rock formations, such as the Marcellus and Eagle Ford shales. As a result, the U.S. has significantly increased its natural gas output and is now a global leader in shale gas production, transforming its energy landscape.
