Thehistory of the petroleum industry in the United States goes back to the early 19th century, although the indigenous peoples, like many ancient societies, have usedpetroleum 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 theoil 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. US regained the position of the largest oil producing country in the world in 2018 and has kept it every year since as of 2022.[1][2][3]
Native Americans had known of the oil in westernPennsylvania, 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 manufacturekerosene from crude oil, if a sufficiently large oil supply could be found.
TheJesuit Relations of 1657 states:
As one approaches nearer to the country of theCats, 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.[4]
Salt was a valuable commodity, and an industry developed near salt springs in theOhio 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.[5] Early salt brine wells that produced byproduct oil included theThorla-McKee Well of Ohio in 1814, a well nearBurkesville, Kentucky, in 1828,[6] and wells atBurning Springs, West Virginia, by 1836.
The USnatural gas industry started in 1821 atFredonia,Chautauqua County, New York, when William Hart dug a well to a depth of 27 feet (8.2 m) intogas-bearing shale, then drilled a borehole 43 feet (13 m) further, and piped the natural gas to a nearby inn where it was burned for illumination. Soon many gas wells were drilled in the area, and the gas-lit streets of Fredonia became a tourist attraction.

On August 27, 1859,George Bissell andEdwin L. Drake made the first successful use of a drilling rig on a well drilled especially to produce oil, at a site onOil Creek nearTitusville, Pennsylvania. The Drake partners were encouraged byBenjamin Silliman (1779–1864), a chemistry professor atYale, who tested a sample of the oil, and assured them that it could be distilled into useful products such as kerosene for lamps.
The Drake well is often referred to as the first "commercial oil well." Before the Drake well, oil-producing wells in the United States were wells that were drilled for salt brine, and produced oil and gas only as accidental byproducts. Historians have noted that the importance of the Drake well was not in being the first well to produce oil, but in attracting the first great wave of investment in oil drilling, refining, and marketing:
The success of the Drake well quickly led to oil drilling in other locations in the westernAppalachian Mountains, where oil was seeping to the surface, or where salt drillers had previously found oil fouling their salt wells. During theAmerican Civil War, the oil-producing region spread over much of western Pennsylvania, up into westernNew York state, and down theOhio River valley into the states ofOhio,Kentucky, and the western part of Virginia (nowWest Virginia). The Appalachian Basin continued to be the leading oil-producing region in the United States through 1904.[8]
The first commercial oil well in New York was drilled in 1865. New York's (and Northwestern Pennsylvania) crude oil is very high inparaffin.[9]
The principal product of the oil in the 19th century waskerosene, which quickly replacedwhale oil for illuminating purposes in the United States. Originally dealing in whale oil which was widely used for illumination,Charles Pratt (1830–1891) of Massachusetts was an early pioneer of the naturaloil industry in the United States. He was founder ofAstral Oil Works in the Greenpoint section ofBrooklyn, New York. Pratt's product later gave rise to the slogan, "The holy lamps of Tibet are primed with Astral Oil." He joined with his protégéHenry H. Rogers to formCharles Pratt and Company in 1867. Both companies became part ofJohn D. Rockefeller'sStandard Oil in 1874.
The Mid-continent area is an area generally including Kansas, Oklahoma, Arkansas, North Louisiana and the part of Texas away from the Gulf Coast. The first commercially successful oil well drilled in Kansas was theNorman No. 1 near Neodesha, Kansas, on November 28, 1892.
Oil was discovered atBartlesville andBurbank in 1897. But the initial discoveries created no great excitement until the discovery gusher of theGlenn Pool in 1905. The Glenn discovery came when Gulf Coast production was declining rapidly, and the operators were eager for new areas to drill. The increased drilling resulted in major discoveries atCushing in 1912 andHealdton in 1913.[10]
The largest oil field in the lower 48 states, theEast Texas oil field, was not discovered until 1930, when wildcatterColumbus Marion Joiner (more commonly known as "Dad" Joiner) drilled the Daisy Bradford No. 3 well, inRusk County, Texas.[11]
In 1906, the Caddo-Pine Island Field in northern Caddo Parish, Louisiana was discovered, and a rush of leasing and drilling activity ensued. In 1908, the first natural gas pipeline was constructed to transport gas from Caddo-Pine Island to Shreveport, Louisiana. This was one of the earliest commercial uses of natural gas, which was commonly viewed as an undesirable by-product of oil production and often "flared" or burnt off at the well site.
Other innovations in the Caddo-Pine Island Field included the first over-water oil platform, which was constructed in the field on Caddo Lake in 1910. In that same year, a major oil pipeline was constructed from Caddo-Pine Island Field to a refinery built and operated by Standard Oil Company of Louisiana in Baton Rouge, Louisiana. The refinery continues to operate today.
Other early petroleum discoveries in North Louisiana included the Bull Bayou Field, Red River Parish, Louisiana (1913), Monroe Gas Field, Ouachita Parish, Louisiana (1916), Homer Field, Claiborne Parish, Louisiana (1919) and Haynesville Field, Claiborne Parish, Louisiana (1921).[12]

Native Americans had known of the tar seeps in southernCalifornia for thousands of years, and used the tar to waterproof their canoes. Spanish settlers also knew of the seeps, such as atRancho La Brea (Spanish forTar Ranch) in present-dayLos Angeles, from which the priests obtained tar to waterproof the roofs of the Los Angeles and San Gabriel missions.[13]
Despite the abundance of well-known seeps in southern California, the first commercial oil well in California was drilled inHumboldt County, northern California in 1865.[14]
Some attempts were made in the 1860s to exploit oil deposits under tar seeps in theVentura Basin ofVentura County and northeasternLos Angeles County. The early efforts failed because of complex geology, and, more importantly, because the refining techniques then available could not manufacture high-qualitykerosene from California crude oil, which differed chemically from Pennsylvania crude oil.[15] Most California crude oil in the early years was turned into the less lucrative products of fuel oil and asphalt.
Oil production in theLos Angeles Basin started with the discovery of theBrea-Olinda Oil Field in 1880, and continued with the development of theLos Angeles City Oil Field in 1893, theBeverly Hills Oil Field in 1900, theSalt Lake Oil Field in 1902, and many others. The discovery of theLong Beach Oil Field in 1921, which proved to be the world's richest in production per-acre of the time, increased the importance of the Los Angeles Basin as a worldwide oil producer. This increased again with the discovery of theWilmington Oil Field in 1932, and the development of the Port of Los Angeles as a means of shipping crude oil overseas.[16]
Production in Santa Barbara County began in the 1890s with the development of theSummerland Oil Field, which included the world's first offshore oil wells. With the discovery of theOrcutt andLompoc fields, northern Santa Barbara County became a regional center of production; towns such asOrcutt owe their existence to the quickly growing industry.[16]
Oil in theSan Joaquin Basin was first discovered at theCoalinga field in 1890. By 1901, the San Joaquin Basin was the main oil-producing region of California, and it remains so in the 21st century, with huge oil fields including theMidway-Sunset,Kern River, andBelridge fields producing much of California's onshore oil.
The first commercial oil well in the Rocky Mountains was drilled nearCañon City, Colorado in 1862. The wells in the Cañon City-Florence field, drilled near surface oil seeps, produced from fractures in thePierre Shale.
A Russian sea captain noted oil seeps along the shore of theCook Inlet as early as 1853, and oil drilling began in 1898 in a number of locations along the southern coast ofAlaska.[17] Production was relatively small, however, until huge discoveries were made on Alaska's remoteNorth Slope.
Petroleum seeps on the North Slope have been known for many years, and in 1923, the federal government created US Naval Petroleum Reserve No. 4 to cover the presumed oil fields beneath the seeps. Some exploration drilling was done in the reserve duringWorld War II and the 1950s, but the remote location deterred intensive exploration until the 1960s. ThePrudhoe Bay Oil Field, the largest oil field in the United States in terms of total oil produced, was discovered in 1968. Production began in 1977, following completion of theTrans-Alaska Pipeline. Through 2005, the field has produced 13 billion barrels (2.1×10^9 m3) of oil (an average of 1.5 million barrels/day), and is estimated to contain another 2 billion barrels (320×10^6 m3) of economically recoverable oil.
In the late 1800s, a number of oil refineries were concentrated in the Greenpoint area ofBrooklyn, beginning withAstral Oil Works in 1867. In the 1970s, theGreenpoint oil spill was discovered, one of the largest spills in the history of the United States.

Capt.Anthony Francis Lucas, an experienced mining engineer and salt driller, drilled a well to find oil atSpindletop Hill. On the morning of January 10, 1901, the little hill south ofBeaumont, Texas began to tremble and mud bubbled up over the rotary table. A low rumbling sound came from underground, and then, with a force that shot 6 tons of 4-inch (100 mm) diameter pipe out over the top of the derrick, knocking off the crown block, the Lucas Gusher roared in and the Spindletop oil field was born. Spindletop became the focus of frenzied drilling; oil production from the field peaked in 1902 at 17,400,000 barrels (2,770,000 m3), but by 1905 production had declined 90% from the peak.[18]
Spindletop Hill turned out to be the surface expression of an undergroundsalt dome, around which the oil accumulated. The Spindletop gusher started seriousoil exploration of theGulf Coast inTexas andLouisiana, an area that had previously been dismissed by oil men. Other salt dome mounds were quickly drilled, resulting in discoveries atSour Lake (1902),Batson (1904) andHumble (1905).[19]
TheStandard Oil Company was slow to appreciate the economic potential of the Spindletop oil field, and the Gulf Coast generally, which gave greater opportunity to others; Spindletop became the birthplace of oil giantsTexaco andGulf Oil. Although in 1899 Standard Oil controlled more than 85% of the oil production in the older oil regions in theAppalachian Basin and the Lima-Indiana trend, it never controlled more than 10% of the oil production in the new Gulf Coast province.[20]
By theNatural Gas Act of 1938, the federal government imposed price controls on natural gas in interstate commerce. TheFederal Power Commission was mandated to set interstate gas prices at "just and reasonable" rates.[21] The FPC at first only regulated the price at which pipelines sold gas to utilities and industry, but later put limits on the wellhead price of gas sold to an interstate pipeline. Gas producers challenged the controls, but lost in the Supreme Court inPhillips Petroleum Co. v. Wisconsin (1954).
The federal government had controlled the price of natural gas that crossed state lines, but not of gas produced and sold within a state. In the 1970s, the low interstate price set by the federal government caused supply shortages of gas in consuming states, because gas producers sold as much as they could of their product for higher prices in the local markets within gas-producing states. In the Natural Gas Policy Act of 1978, the federal government extended price controls to all natural gas in the country. At the same time, the government created a complex price system in which the price paid to the producer depended on the date the well was drilled, the depth of the well, the geological formation, the distance to other gas wells, and several other factors. The price system was an attempt to keep the average price low while encouraging new production.[22]
The last federal price controls on natural gas were removed by the Natural Gas Decontrol Act of 1989, which phased out the last remaining price control as of 1 January 1993.[23]
Hydraulic fracturing experiments began in the 1940s in the United States. Massive hydraulic fracturing, generally involving injecting over 150 short tons, or approximately 300,000 pounds (136 metric tonnes), ofproppant, was first applied byPan American Petroleum inStephens County, Oklahoma, USA in 1968.[24] By the 1970s, massive hydraulic fracturing was employed in Canada, Germany, the Netherlands, and the United Kingdom in theNorth Sea.[25] Hydraulic fracturing operations have grown exponentially since the mid-1990s, when technologic advances and increases in the price of natural gas made this technique economically viable.[26]
Oil rig technology advanced rapidly in the 20th century, with many innovations made by US companies operating in the Gulf of Mexico. The firstjackup oil rig was used in the Gulf of Mexico in 1954.
A number of major environmental incidents in the United States in the 20th Century are linked to the petroleum industry.
In 1910, theLakeview Gusher in Kern County, California was a well blowout that created the largest accidental oil spill in history.[27]
The1969 Santa Barbara oil spill occurred in theSanta Barbara Channel, near the city ofSanta Barbara inSouthern California. It was the largest oil spill inUnited States waters by that time, and now ranks third after the 2010Deepwater Horizon and 1989Exxon Valdez spills. It remains the largest oil spill to have occurred in the waters off California. The public outrage engendered by the spill, which received prominent media coverage in the United States, resulted in numerous pieces of environmental legislation within the next several years, legislation that forms the legal and regulatory framework for the modernenvironmental movement in the U.S.[28][29][30][31][32]
The 1989Exxon Valdez oil spill off the coast ofAlaska was the largest spill in US waters up to that date, as of 2020 only exceeded by the 2010Deepwater Horizon oil spill, in terms of volume released.[33]
In 2010 theDeepwater Horizon oil spill in theGulf of Mexico became the largest marine oil spill in the history of the petroleum industry.
Beginning in 2004, theTaylor oil spill in theGulf of Mexico continues as of 2020.

TheNorth Dakota oil boom, lasting from 2006 to 2015, involved rapidly expanding oil extraction from theBakken formation in the state ofNorth Dakota. The boom began with the discovery ofParshall Oil Field in 2006, and peaked in 2012,[35][36] but with substantially less growth noted since 2015 due to a global decline in oil prices.[37] The boom relied uponhorizontal drilling andhydraulic fracturing to recover oil fromtight oil deposits.[38]
Commissioned in 2010, theKeystone Pipeline is anoil pipeline system in Canada and the United States, as of 2019 owned solely byTC Energy.[39] It runs from theWestern Canadian Sedimentary Basin inAlberta to refineries inIllinois andTexas, and also to oiltank farms and an oil pipeline distribution center inCushing, Oklahoma.[40] The pipeline became well known when a planned fourth phase,Keystone XL, attracted opposition from environmentalists, becoming a symbol of the battle overclimate change and fossil fuels.
