U.S. daily crude oil production by PADD 2017-2021

PADD 3 (Gulf Coast), which includes the oil production in Alabama, Arkansas, Louisiana, Mississippi, New Mexico, and Texas, was the largest oil producing PADD, having produced some 7.9 million barrels of crude oil per day in 2021. This was a increase by roughly two million barrels daily compared to 2017. PADDs were created during World War II (under the Petroleum Administration for War) in order to help organize the allocation of fuels from petroleum products (gasoline, diesel, etc.). For data collection purposes these regions are still used today.

PADD 3（墨西哥湾沿岸），涵盖阿拉巴马州、阿肯色州、路易斯安那州、密西西比州、新墨西哥州和德克萨斯州的石油产量，是最大的石油生产区域。2021年，该区域日均产原油约790万桶，相较于2017年，日均产量增长了约200万桶。PADD区域是在第二次世界大战期间（在战争石油管理局之下）建立，旨在协助石油产品（汽油、柴油等）的燃料分配组织。出于数据收集的目的，这些区域至今仍被沿用。
