Spinletop is a salt dome oil field located in south Beaumont, Texas (approx. 30.02 -94.07) in the United States. On January 10, 1901, a well at Spindletop struck oil ("came in"), marking the birthdate of the modern petroleum industry. At 100,000 barrels (16,000 m³) of oil a day, the gusher tripled U.S. oil production overnight. Some of the companies chartered to exploit the wealth of Spindletop, such as Gulf Oil and Texaco, are part of today's Chevron Corporation.
