Not all of the petrochemical or commodity chemical materials produced by

276-515: A lighting and heating fuel, the demand for petroleum increased greatly, and by the early twentieth century had become the most valuable commodity traded on world markets. Imperial Russia produced 3,500 tons of oil in 1825 and doubled its output by mid-century. After oil drilling began in the region of present-day Azerbaijan in 1846, in Baku , the Russian Empire built two large pipelines:

322-557: A market share. For example: 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: While some upstream companies carry out certain midstream operations, the midstream sector is dominated by a number of companies that specialize in these services. Midstream companies include: The oil and gas industry spends only 0.4% of its net sales on research & development (R&D) which

368-475: A new company was formed for East Pakistan named Burmah Eastern Limited which was listed on the stock exchange and the majority of its shareholding was held by Pakistanis. In 1970, it was listed on the Karachi Stock Exchange and the company was renamed as Pakistan Burmah Shell (PBS) Limited. The Shell and Burmah Groups retained a 49 percent share, split evenly while National Investment Trust ,

414-535: A state-owned fund, owned a majority stake. In February 1993, during a period of economic liberalization , Burmah divested from PBS, allowing Shell Petroleum to increase its stake to 51 percent. Over time, Shell Petroleum further increased its share to 77.42 percent in the early 2000s. In 2024, Asyad Holding, a Saudi based group through UAE-based Wafi Energy Holding Limited acquired 77.42 percent shareholdings and control of Shell Pakistan Limited. Shell used to provide jet fuel at five major airfields across Pakistan and

460-652: Is generally accepted that oil is formed mostly from the carbon rich remains of ancient plankton after exposure to heat and pressure in Earth 's crust over hundreds of millions of years. Over time, the decayed residue was covered by layers of mud and silt, sinking further down into Earth's crust and preserved there between hot and pressured layers, gradually transforming into oil reservoirs . Petroleum in an unrefined state has been utilized by humans for over 5000 years. Oil in general has been used since early human history to keep fires ablaze and in warfare . Its importance to

506-521: Is in comparison with a range of other industries the lowest share. Governments such as the United States government provide a heavy public subsidy to petroleum companies , with major tax breaks at various stages of oil exploration and extraction, including the costs of oil field leases and drilling equipment. In recent years, enhanced oil recovery techniques – most notably multi-stage drilling and hydraulic fracturing ("fracking") – have moved to

Polyethylene terephthalate (PET) bottles are made from ethylene and paraxylene . In 1949, Fritz Stastny turned polystyrene into foam. After World War II, polypropylene

598-597: Is often employed by means of aerobic degradation. More recently, other bioremediative methods have been explored such as phytoremediation and thermal remediation. 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 metals . Researchers have discovered that

644-638: Is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical concern for many nations. Oil accounts for a large percentage of the world's energy consumption , ranging from a low of 32% for Europe and Asia, to a high of 53% for the Middle East. Other geographic regions' consumption patterns are as follows: South and Central America (44%), Africa (41%), and North America (40%). The world consumes 36 billion barrels (5.8 km ) of oil per year, with developed nations being

690-682: The United States and Western Europe ; however, major growth in new production capacity is in the Middle East and Asia . There is substantial inter-regional petrochemical trade. Primary petrochemicals are divided into three groups depending on their chemical structure : In 2007, the amounts of ethylene and propylene produced in steam crackers were about 115 M t (megatonnes) and 70 Mt, respectively. The output ethylene capacity of large steam crackers ranged up to as much as 1.0 – 1.5 Mt per year. The adjacent diagram schematically depicts

736-582: The petrochemical industry can produce ground-level ozone pollution at higher amounts in winter than in summer. Greenhouse gases caused by burning fossil fuels drive climate change . In 1959, at a symposium organised by the American Petroleum Institute for the centennial of the American oil industry , the physicist Edward Teller warned of the danger of global climate change . Edward Teller explained that carbon dioxide "in

782-512: The world economy however, evolved slowly, with whale oil being used for lighting in the 19th century and wood and coal used for heating and cooking well into the 20th century. Even though the Industrial Revolution generated an increasing need for energy, this was initially met mainly by coal, and from other sources including whale oil. However, when it was discovered that kerosene could be extracted from crude oil and used as

828-590: The 1880s. In the early 1930s 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 14 feet (4.3 m) of water, one mile (1.6 km) offshore of Calcasieu Parish, Louisiana . In early 1947 Superior Oil erected

874-625: The 833 km long pipeline to transport oil from the Caspian to the Black Sea port of Batum (Baku-Batum pipeline), completed in 1906, and the 162 km long pipeline to carry oil from Chechnya to the Caspian. The first drilled oil wells in Baku were built in 1871–1872 by Ivan Mirzoev , an Armenian businessman who is referred to as one of the 'founding fathers' of Baku's oil industry. At

920-679: The Burmah Shell Oil Storage & Distribution Company of India. After Pakistan gained independence in 1947, the company was renamed as Burmah Shell Oil Distribution Company of Pakistan. During the 1950s, Shell Pakistan, then known as Burmah Shell, employed notable strategies for promoting kerosene oil, featuring popular singers such as Mohammed Rafi in their advertisements . In 1965, Shell sold half of its stake in Burmah Shell operating in East Pakistan . Later,

966-527: The East Indies oil-supply (especially via submarine campaigns ) considerably weakened Japan in the latter part of the war. After World War II ended in 1945, the countries of the Middle East 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

1012-779: The Middle East. The expansion of Imperial Japan to the south aimed largely at accessing the oil-fields of the Dutch East Indies. Germany, cut off from sea-borne oil supplies by Allied blockade , failed in Operation Edelweiss to secure the Caucasus oil-fields for the Axis military in 1942, while Romania deprived the Wehrmacht of access to Ploesti oilfields – the largest in Europe – from August 1944. Cutting off

1058-1019: The River Mersey in North West England, on the Humber on the East coast of Yorkshire, in Grangemouth near the Firth of Forth in Scotland, and in Teesside as part of the Northeast of England Process Industry Cluster (NEPIC). To demonstrate the clustering and integration, some 50% of the United Kingdom's petrochemical and commodity chemicals are produced by the NEPIC industry cluster companies in Teesside. In 1835, Henri Victor Regnault ,

1104-764: 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 and 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: Oil companies used to be classified by sales as " supermajors " ( BP , Chevron , ExxonMobil , ConocoPhillips , Shell , Eni and TotalEnergies ), "majors", and "independents" or "jobbers". In recent years however, National Oil Companies (NOC, as opposed to IOC, International Oil Companies) have come to control

1150-527: 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

1196-628: The atmosphere causes a greenhouse effect " and that burning more fossil fuels could "melt the icecaps and submerge New York". The Intergovernmental Panel on Climate Change , founded by the United Nations in 1988, concludes that human-sourced greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century. As a result of climate change concerns, many people have begun using other methods of energy such as solar and wind. This recent shift has some petroleum enthusiasts skeptical about

1242-445: The building-blocks for a wide range of materials such as solvents , detergents , and adhesives . Olefins are the basis for polymers and oligomers used in plastics , resins , fibers , elastomers , lubricants , and gels . Global ethylene production was 190 million tonnes and propylene was 120 million tonnes in 2019. Aromatics production is approximately 70 million tonnes. The largest petrochemical industries are located in

1288-468: The chemical industry are made in one single location but groups of related materials are often made in adjacent manufacturing plants to induce industrial symbiosis as well as material and utility efficiency and other economies of scale . This is known in chemical engineering terminology as integrated manufacturing. Specialty and fine chemical companies are sometimes found in similar manufacturing locations as petrochemicals but, in most cases, they do not need

1334-523: The first ever well drilled with percussion tools to a depth of 21 meters for oil exploration. In 1878 Ludvig Nobel and his Branobel company "revolutionized oil transport" by commissioning the first oil tanker 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

1380-555: The first modern oil-refineries near Jasło (then in the Austrian dependent Kingdom of Galicia and Lodomeria in 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,

1426-617: 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 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 , Venezuela and North and West Africa. With

1472-578: 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) 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 . The Anglo-Soviet invasion of Iran (1941) secured Allied control of oil-production in

1518-631: The first true modern oil well , touched off a major boom. In the first quarter of the 20th century, the United States overtook Russia as the world's largest oil producer. By the 1920s, oil fields had been established in many countries including Canada, Poland, Sweden, Ukraine, the United States, Peru and Venezuela. The first successful oil tanker , the Zoroaster , was built in 1878 in Sweden, designed by Ludvig Nobel . It operated from Baku to Astrakhan . A number of new tanker designs developed in

1564-812: The forefront of the industry as this new technology plays a crucial and controversial role in new methods of oil extraction. 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

1610-520: The future of the industry. Petrochemical The two most common petrochemical classes are olefins (including ethylene and propylene ) and aromatics (including benzene , toluene and xylene isomers ). Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions. Chemical plants produce olefins by steam cracking of natural gas liquids like ethane and propane . Aromatics are produced by catalytic reforming of naphtha . Olefins and aromatics are

1656-539: The industry are fuel oil and gasoline (petrol). Petroleum is also the raw material for many chemical products , including pharmaceuticals , solvents , fertilizers , pesticides , synthetic fragrances , and plastics . The industry is usually divided into three major components: upstream , midstream , and downstream . Upstream regards exploration and extraction of crude oil , midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products . Petroleum

1702-417: The largest consumers. The United States consumed 18% of the oil produced in 2015. The production, distribution, refining, and retailing of petroleum taken as a whole represents the world's largest industry in terms of dollar value. Petroleum is a naturally occurring liquid found in rock formations. It consists of a complex mixture of hydrocarbons of various molecular weights, plus other organic compounds. It

1748-453: The major hydrocarbon sources and processes used in producing petrochemicals. Like commodity chemicals , petrochemicals are made on a very large scale. Petrochemical manufacturing units differ from commodity chemical plants in that they often produce a number of related products. Compare this with specialty chemical and fine chemical manufacture where products are made in discrete batch processes. Petrochemicals are predominantly made in

1794-590: The refining industry grew in the area. The 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

1840-612: The region. A significant historical marker from this period is a storage tank from 1898. The company's documented presence in the Indian subcontinent began in 1903 when The Shell Transport & Trading Company and the Royal Dutch Petroleum Company formed a partnership to supply petroleum to Asia. In 1928, Royal Dutch Shell merged its marketing interests in India with those of Burmah Oil Company Limited, creating

1886-558: 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 reserves 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

1932-476: The same level of large-scale infrastructure (e.g., pipelines, storage, ports, and power, etc.) and therefore can be found in multi-sector business parks. The large-scale petrochemical manufacturing locations have clusters of manufacturing units that share utilities and large-scale infrastructures such as power stations, storage tanks, port facilities, road and rail terminals. In the United Kingdom, for example, there are four main locations for such manufacturing: near

1978-464: The transportation sector as well as heavy-duty brands to industrial customers and power sector customers. It is the second-largest oil marketing company (OMC) and the largest private OMC in Pakistan with a 25% share of the white-oils market. The Retail business comprises over 800 retail outlets. In August 2001, a new company called Pak-Arab Pipeline Company (PAPCO) was formed to construct and operate

2024-602: The turn of the 20th century, Imperial Russia's output of oil, almost entirely from the Apsheron Peninsula , accounted for half of the world's production and dominated international markets. Nearly 200 small refineries operated in the suburbs of Baku by 1884. As a side effect of these early developments, the Apsheron Peninsula emerged as the world's "oldest legacy of oil pollution and environmental negligence". In 1846 Baku (Bibi-Heybat settlement) featured

2070-411: 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 reservoir . The discovery at Oil Springs touched off an oil boom which brought hundreds of speculators and workers to

2116-505: Was the second largest Jet fuel supplier in Pakistan until 2022 when it discontinued the operations in aviation sector. It is the largest lubricant marketing company in Pakistan with over 20% share of the total lubricant market in the country. SPL's lubricant business is the second most profitable within Shell's Global Lubricant portfolio. The business is focused on sales of key Shell brands (Rimula, Helix & Advance) to high street traders and
