Hydraulic fracturing in the United States - Wikipedia

Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.
