Increases in U.S. Oil Production Predominantly Light, Sweet Crude

U.S. crude oil production has grown rapidly in recent years, primarily from light, sweet crude from tight resource formations. About 90% of the nearly 3MMbpd growth in production from 2011 to 2014 consisted of light, sweet grades, meaning they have an API gravity of 40 or above and a sulphur content of 0.3% or less. EIA's <em>Annual Energy Outlook 2015</em> projects the U.S. supply of lighter API gravity crude oil from formations in regions such as the Bakken, Permian Basin, and Eagle Ford continues to outpace that of medium and heavier crudes.
