The United States likely surpassed Russia and Saudi Arabia to become the world's largest crude oil producer earlier this year, based on preliminary estimates in EIA's Short-Term Energy Outlook (STEO).

In February, U.S. crude oil production exceeded that of Saudi Arabia for the first time in more than two decades. In June and August, the United States surpassed Russia in crude oil production for the first time since February 1999.

Although EIA does not publish crude oil production forecasts for Russia and Saudi Arabia in STEO, EIA expects that U.S. crude oil production will continue to exceed Russian and Saudi Arabian crude oil production for the remaining months of 2018 and through 2019.

U.S. crude oil production, particularly from light sweet crude oil grades, has rapidly increased since 2011. Much of the recent growth has occurred in areas such as the Permian Basin in western Texas and eastern New Mexico, the Federal Offshore Gulf of Mexico, and the Bakken region in North Dakota and Montana.
