History of the petroleum industry in the United States

The history of the petroleum industry in the United States goes back to the early 19th century, although the indigenous peoples, like many ancient societies, have used petroleum seeps since prehistoric times; where found, these seeps signaled the growth of the industry from the earliest discoveries to the more recent.

Petroleum became a major industry following the oil discovery at Oil Creek Pennsylvania in 1859. For much of the 19th and 20th centuries, the US was the largest oil producing country in the world. As of October 2015, the US was the world's third-largest producer of crude oil.

Indians had known of the oil in western Pennsylvania, and had made some use of it for many years before the mid-19th century. Early European explorers noted seeps of oil and natural gas in western Pennsylvania and New York. Interest grew substantially in the mid-1850s as scientists reported on the potential to manufacture kerosene from crude oil, if a sufficiently large oil supply could be found.

The Jesuit Relations of 1657 states:

As one approaches nearer to the country of the Cats, one finds heavy and thick water, which ignites like brandy, and boils up in bubbles of flame when fire is applied to it. It is, moreover, so oily, that all our Savages use it to anoint and grease their heads and their bodies.

Salt was a valuable commodity, and an industry developed near salt springs in the Ohio River Valley, producing salt by evaporating brine from the springs. Salt wells were sunk at the salt springs to increase the supply of brine for evaporation. Some of the wells were hand-dug, but salt producers also learned to drill wells by percussion (cable tool) methods. In a number of locations in western Virginia, Ohio, and Kentucky, oil and natural gas came up the wells along with the brine. The oil was mostly a nuisance, but some salt producers saved it and sold it as illuminating oil or medicine. In some locations, enough natural gas was produced to be used as fuel for the salt evaporating pans. Early salt brine wells that produced byproduct oil included the Thorla-McKee Well of Ohio in 1814, a well near Burkesville, Kentucky, in 1828, and wells at Burning Springs, West Virginia, by 1836.
