where does most of the oil in the us come from
United States energy independence In total energy consumption, the U.S. was between 86% and 91% self-sufficient in 2016.[1] In May 2011, the country became a net exporter of refined petroleum products.[2] As of 2014, the United States was the world's third-largest producer of crude oil, after Saudi Arabia and Russia.[3] and second largest exporter of refined products, after Russia.[4]
North Sea oil Commercial extraction of oil on the shores of the North Sea dates back to 1851, when James Young retorted oil from torbanite (boghead coal, or oil shale) mined in the Midland Valley of Scotland.[1] Across the sea in Germany, oil was found in the Wietze field near Hanover in 1859, leading to the discovery of seventy more fields, mostly in Lower Cretaceous and Jurassic reservoirs, producing a combined total of around 1340 mÂ³ (8,400 barrels) per day.[1]
