The United States is the world's largest crude oil producer. In 2023, it had an output of 19.4 million barrels worth of oil per day. This was nearly 12 million barrels more than in 2010 and largely a result of advances in unconventional tight oil production. Saudi Arabia and Russia ranked second and third, at around 11.4 and 11.1 million barrels daily respectively. Oil production includes crude oil, shale oil, oil sands, and natural gas liquids. Distribution of U.S. oil production The U.S. is divided into five regional divisions for oil production, known as Petroleum Administration for Defense District’s (PADD), which were created during World War II. The main goal was to organize the allocation of fuels from petroleum products and for data collection purposes these regions are still currently used. Out of all PADD's, PADD 3, including the Gulf Coast states, has recorded by far the largest daily crude oil production, at some 7.9 million barrels in 2021. By comparison, PADD 1 (East Coast) production volumes were 74 thousand barrels per day. The importance of PADD 3 to the country’s overall oil output is hardly surprising as Texas is by far the state with the largest crude oil production. U.S. natural gas production Besides being the world's largest oil producer, the U.S. is also the world’s largest natural gas producer. It produced over 934 billion cubic meters in 2021, despite ranking fifth in terms of proved natural gas reserves .
