The U.S. Energy Information Administration (EIA) estimates that in 2019, about 2.81 billion barrels (or 7.7 million barrels per day) of crude oil were produced directly from tight oil resources in the United States. This was equal to about 63% of total U.S. crude oil production in 2019. Tight oil is oil embedded in low-permeable shale, sandstone, and carbonate rock formations.
