Crude oil surpassed hydrocarbon gas liquids (HGL) to become the largest U.S. petroleum export, with 1.8 million barrels per day (b/d) of exports in the first half of 2018. U.S. crude oil exports increased by 787,000 b/d, or almost 80%, from the first half of 2017 to the first half of 2018 and set a new monthly record of 2.2 million b/d in June. Much of this crude oil went to destinations in Asia and Oceania such as China, South Korea, and India. Europe was the second-largest market for U.S. crude oil exports, led by Italy, the United Kingdom, and the Netherlands. Canada was the only major U.S. crude oil export destination where exports decreased, down slightly in the first half of 2018 compared with the same period in 2017.
