when was oil discovered in the north sea
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]
Base oil The least refined type which produced by Solvent Refining. It usually consists of conventional petroleum base oils.

Deepwater Horizon oil spill Concerns were raised about the appearance of underwater, horizontally extended plumes of dissolved oil. Researchers concluded that deep plumes of dissolved oil and gas would likely remain confined to the northern Gulf of Mexico and that the peak impact on dissolved oxygen would be delayed and long lasting.[61] Two weeks after the wellhead was capped on 15 July 2010, the surface oil appeared to have dissipated, while an unknown amount of subsurface oil remained.[62] Estimates of the residual ranged from a 2010 NOAA report that claimed about half of the oil remained below the surface to independent estimates of up to 75%.[63][64][65]
