The Lakeview Gusher was an eruption of hydrocarbons from a pressurized oil well in the Midway-Sunset Oil Field in Kern County, California, in 1910. Caused by a blowout, it created the largest accidental oil spill in history, lasting 18 months and releasing an estimated 9 Moilbbl of crude oil. Midway-Sunset was one of the largest oil reserves in the United States. When drilling commenced, the Lakeview Oil Company expected natural gas and a small amount of oil. Instead, there was a large blowout which overloaded storage tanks. The geyser released more than 1.2 e6ST of crude oil, far more than any other single leak on land or water. Its site is located about a half-mile (800 m) east of the Taft–Maricopa Highway, California Route 33, marked by a Caltrans guide sign and a bronze plaque designated as California Historical Landmark number 485.

Background

The Lakeview Oil Company, organized by Julius Fried, R.D. Wade, F.E. Dunlap, and Charles F. Off started drilling at its Number One well on 1 January 1909. According to legend, Fried had picked the spot because of an assumption that clumps of red grass indicated good oil land. Initially only natural gas was found. As work continued the company exhausted funds and partnered with the Union Oil Company, which wanted to build storage tanks there. Early twentieth-century drilling technology lacked such modern safety features as blowout preventers. When drilling reached a well depth of 2440 ft on 15 March 1910, pressurized oil blew through the well casing above the bit. An estimated 9 Moilbbl escaped before the gusher was brought under control in September 1911. The initial daily flow was 18800 oilbbl, creating a river of crude that crews rushed to contain with improvised sand bag dams and dikes. Peak flow reached 90000 oilbbl per day, diverted via a pipeline to storage tanks 2.5 mi away, where an 8 in line led to Port Avila on the coast. In total, 378 million gallons of oil was released, and about 40% was captured. This surplus dropped the price to 30 cents a barrel, about half of what it was prior to the blowout. No fire or dangerous flooding resulted from this spill.
