and launching it on the [[Caspian Sea. [[Samuel Kier established America's first oil refinery in Pittsburgh on Seventh avenue near Grant Street in 1853. [[Ignacy Łukasiewicz built one of the first modern oil-refineries near [[Jasło (then in the Austrian dependent [[Kingdom of Galicia and Lodomeria in [[Galicia (Central Europe)|Central European Galicia), present-day Poland, in 1854–56. Galician refineries were initially small, as demand for refined fuel was limited. The refined products were used in artificial asphalt, machine oil and lubricants, in addition to Łukasiewicz's [[kerosene lamp. As kerosene lamps gained popularity, the refining industry grew in the area. The [[History of the petroleum industry in Canada#Early origins|first commercial oil-well in Canada became operational in 1858 at [[Oil Springs, Ontario (then [[Canada West). Businessman [[James Miller Williams dug several wells between 1855 and 1858 before discovering a rich reserve of oil four metres below ground. Williams extracted 1.5 million litres of crude oil by 1860, refining much of it into kerosene-lamp oil. Some historians challenge Canada's claim to North America's first [[oil field, arguing that [[Pennsylvania's famous [[Drake Well was the continent's first. But there is evidence to support Williams, not least of which is that the Drake well did not come into production until August 28, 1859. The controversial point might be that Williams found oil above bedrock while [[Edwin Drake’s well located oil within a bedrock [[oil reservoir|reservoir. The discovery at Oil Springs touched off an oil boom which brought hundreds of speculators and workers to the area. Canada's first gusher (flowing well) erupted on January 16, 1862, when local oil-man John Shaw struck oil at 158 feet (48 m). For a week the oil gushed unchecked at levels reported as high as 3,000 barrels per day. The first modern oil-drilling in the United States began in West Virginia and Pennsylvania in the 1850s. [[Edwin Drake's 1859 well near [[Titusville, Pennsylvania, typically considered the first true modern [[oil well, touched off a major boom.John Steele Gordon
"10 Moments That Made American Business," ''American Heritage'', February/March 2007 - "Drake, who seems to have awarded himself the title of colonel by which he is often known, had a great deal of trouble persuading a salt-drilling crew to try to drill for oil, but on August 27, 1859, he struck it at 69 feet."

In the early 1930s [[Texaco|the Texas Company developed the first mobile steel barges for drilling in the brackish coastal areas of the [[Gulf of Mexico. In 1937 [[Pure Oil Company (now part of [[Chevron Corporation) and its partner [[Superior Oil Company (now part of [[ExxonMobil Corporation) used a fixed platform to develop a field in of water, one mile (1.6 km) offshore of [[Calcasieu Parish, Louisiana. In early 1947 Superior Oil erected a drilling/production [[oil platform|oil-platform in of water some 18 miles off [[Vermilion Parish, Louisiana. [[Kerr-McGee Oil Industries, as operator for partners [[Phillips Petroleum ([[ConocoPhillips) and [[Stanolind Oil & Gas ([[BP), completed its historic Ship Shoal Block 32 well in November 1947, months before Superior actually drilled a discovery from their Vermilion platform farther offshore. In any case, that made Kerr-McGee's Gulf of Mexico well, Kermac No. 16, the first oil discovery drilled out of sight of land. Forty-four Gulf of Mexico exploratory wells discovered 11 oil and natural gas fields by the end of 1949. During [[World War II (1939–1945) [[Oil campaign of World War II|control of oil supply from Romania, Baku, the Middle East and the [[Dutch East Indies played a huge role in the events of the war and the ultimate victory of the [[Allies of World War II|Allies.

took the lead in oil production from the United States. Important developments since World War II include deep-water drilling, the introduction of the [[drillship, and the growth of a global shipping network for petroleum relying upon oil tankers and pipelines. In 1949 the first offshore oil-drilling at Oil Rocks (Neft Dashlari) in the Caspian Sea off Azerbaijan eventually resulted in a city built on pylons. In the 1960s and 1970s, multi-governmental organizations of oil–producing nations [[OPEC and [[Organization of Arab Petroleum Exporting Countries|OAPEC played a major role in setting petroleum prices and policy. [[Oil spills and their cleanup have become an issue of increasing political, environmental, and economic importance. New fields of hydrocarbon production developed in places such as Siberia, [[Sakhalin, [[History of the Venezuelan oil industry|Venezuela and North and West Africa. With the advent of hydraulic fracturing and other [[horizontal drilling techniques, shale play has seen an enormous uptick in production. Areas of shale such as the [[Permian Basin (North America)|Permian Basin and [[Eagle Ford Shale|Eagle-Ford have become huge hotbeds of production for the largest oil corporations in the United States.


The [[American Petroleum Institute divides the petroleum industry into five sectors: * [[Upstream (oil industry)|upstream ([[oil exploration|exploration, development and production of crude oil or natural gas) * [[Downstream (oil industry)|downstream ([[Tanker (ship)|oil tankers, [[oil refinery|refiners, retailers and consumers) * [[Pipeline transport|pipeline * marine * service and supply


[[Oil companies used to be classified by sales as ''"[[supermajors"'' ([[BP, [[Chevron Corporation|Chevron, [[ExxonMobil, [[ConocoPhillips, [[Royal Dutch Shell|Shell, [[Eni and [[Total S.A.), ''"majors",'' and ''"independents" or "jobbers".'' In recent years however, National Oil Companies (NOC, as opposed to IOC, International Oil Companies) have come to control the rights over the largest oil reserves; by this measure the top ten companies all are NOC. The following table shows the ten largest national oil companies ranked by reservesRanking by oil reserves and production, 2006 values and by production in 2012. Most upstream work in the [[oil field or on an [[oil well is [[contracted out to drilling contractors and oil field service companies. Aside from the NOCs which dominate the Upstream sector, there are many international companies that have a market share.

[[Midstream operations are sometimes classified within the downstream sector, but these operations compose a separate and discrete sector of the petroleum industry. Midstream operations and processes include the following: * Gathering: The gathering process employs narrow, low-pressure pipelines to connect oil- and gas-producing wells to larger, long-haul pipelines or processing facilities. * Processing/refining: Processing and refining operations turn crude oil and gas into marketable products.

[[Natural-gas processing|Natural gas processing includes [[Gas compressor|compression; [[glycol dehydration; [[Amine gas treating|amine treating; separating the product into pipeline-quality natural gas and a stream of mixed natural gas liquids; and fractionation, which separates the stream of mixed natural gas liquids into its components. The fractionation process yields [[ethane, [[propane, [[butane, [[isobutane, and [[natural gasoline. * Transportation: Oil and gas are transported to processing facilities, and from there to end users, by [[Pipeline transport|pipeline, [[Barge|tanker/barge, [[Trucking industry in the United States|truck, and [[Rail transport|rail. Pipelines are the most economical transportation method and are most suited to movement across longer distances, for example, across continents. Tankers and barges are also employed for long-distance, often international transport. Rail and truck can also be used for longer distances but are most cost-effective for shorter routes. * Storage: Midstream service providers provide storage facilities at [[Oil depot|terminals throughout the oil and gas distribution systems. These facilities are most often located near refining and processing facilities and are connected to pipeline systems to facilitate shipment when product demand must be met. While petroleum products are held in storage tanks, natural gas tends to be stored in underground facilities, such as salt dome caverns and depleted reservoirs. * Technological applications: Midstream service providers apply technological solutions to improve efficiency during midstream processes. Technology can be used during compression of fuels to ease flow through pipelines; to better detect [[Leak detection|leaks in pipelines; and to automate communications for better pipeline and equipment monitoring. While some upstream companies carry out certain midstream operations, the midstream sector is dominated by a number of companies that specialize in these services.

Environmental impact

Water pollution

Some petroleum industry operations have been responsible for [[water pollution through by-products of refining and [[oil spills. Though hydraulic fracturing has significantly increased natural gas extraction, there is some belief and evidence to support that consumable water has seen increased in methane contamination due to this gas extraction. Leaks from underground tanks and abandoned refineries may also contaminate groundwater in surrounding areas. Hydrocarbons that comprise refined petroleum are resistant to biodegradation and have been found to remain present in contaminated soils for years. To hasten this process, [[bioremediation of petroleum hydrocarbon pollutants is often employed by means of aerobic degradation. More recently, other bioremediative methods have been explored such as [[phytoremediation and thermal remediation.

Air pollution

The industry is the largest industrial source of emissions of volatile organic compounds (VOCs), a group of chemicals that contribute to the formation of ground-level [[ozone ([[smog). The combustion of fossil fuels produces [[greenhouse gases and other air pollutants as by-products. Pollutants include [[nitrogen oxides, [[sulphur dioxide, [[volatile organic compounds and [[Heavy metal (chemistry)|heavy metals. Researchers have discovered that the [[petrochemical industry can produce ground-level ozone pollution at higher amounts in winter than in summer.

Climate change

The [[greenhouse gases due to [[fossil fuels drive [[climate change. Already in 1959, at a symposium organised by the [[American Petroleum Institute for the centennial of the [[American oil industry, the [[physicist [[Edward Teller warned then of the danger of global [[climate change. Edward Teller explained that carbon dioxide "in the atmosphere causes a [[greenhouse effect" and that burning more [[fossil fuels could "melt the icecap and submerge New York".Benjamin Franta
"On its 100th birthday in 1959, Edward Teller warned the oil industry about global warming"
''[[The Guardian'', 1 January 2018 (page visited on 2 January 2018).
The [[Intergovernmental Panel on Climate Change, founded by the [[United Nations in 1988, concludes that [[Human impact on the environment|human-sourced [[greenhouse gases are [[Attribution of recent climate change|responsible for most of the [[Instrumental temperature record|observed temperature increase since the middle of the twentieth century. As a result of climate change concerns, many alternative energy enthusiasts have begun using other methods of energy such as solar and wind, among others. This recent view has some petroleum enthusiasts skeptical about the true future of the industry.
