What is the worlds largest oil spill?

The worst oil spill ever happend in march 15, 1910 in Kern County, California when a man named Julius Fried bought a patch of land hoping to strike it rich with oil. Months passed and the drill hit 2,200 feet (670 meters) below the surface, and the well erupted and gushed uncontrollably for 18 months spewing 9 million barrels of oil. About 5 million barrels were captured and sold.
