Spindletop is a salt dome oil field located in the southern portion of Beaumont, Texas in the United States. The Spindletop dome was derived from the Louann Salt evaporite layer of the Jurassic geologic period. On January 10, 1901, a well at Spindletop struck oil ("came in"). The new oil field soon produced more than 100,000 barrels (16,000 m3) of oil per day. Gulf Oil and Texaco, now part of Chevron Corporation, were formed to develop production at Spindletop.
The strike at Spindletop represented a turning point for Texas and the United States; no oil field in the world had ever been so productive. The frenzy of oil exploration and the economic development it generated in the state became known as the Texas Oil Boom. The United States soon became the world's leading oil producer.
