TOP 10 OIL COMPANIES
1. Saudi Aramco – 12mn barrels per day
Leading the way is Saudi Aramco, which produced a staggering 12mn barrels of oil a day in 2014. Widely considered the world's largest oil and gas company, the energy giant turned over more than $1bn in revenue each day last year ($378bn).
Aramco says that it has proven conventional crude oil and condensate reserves of 261.1 billion barrels, as well as natural gas reserves of 294 trillion standard cubic feet (scf).
The organisation is headquartered in Dhahran, Saudi Arabia, with offices and operations throughout the Kingdom of Saudi Arabia, employing more than 61,000 workers worldwide from 77 countries.
Its subsidiaries and affiliates are located in Saudi Arabia, China, Egypt, Japan, India, the Netherlands, the Republic of Korea, Singapore, the United Arab Emirates, the United Kingdom and the United States.
It also have a number of projects either under construction or in the pipeline, which could increase the company’s output yet further.
2. Gazprom – 9.7mn barrels per day
The Russian organisation is best known for its vast gas reserves (Gazprom accounts for 12% and 72% of the global and Russian gas output respectively), but it is also a major global oil producer, averaging 9.7mn barrels per day in 2014. Its array of projects saw the company turnover $106.3bn last calendar year.
Gazprom says it "actively implements large-scale projects aimed at exploiting gas resources of the Yamal Peninsula, Arctic Shelf, Eastern Siberia and the Far East, as well as hydrocarbons exploration and production projects abroad."
In the Middle East, Gazprom announced last year that it had commercial production at the Badra oil field in Iraq. In a project update in June 2015, Gazprom said it had almost doubled production at the field, having brought on a fourth well.
3. National Iranian Oil Company (NIOC) – 6.4mn barrels per day
Iran has hit the headlines in recent months after it agreed a deal in principle with the West to lift sanctions against the country.
Even with the sanctions, Iran is already a significant producer of oil, and it is estimated that NIOC holds 156.53 billion barrels of liquid hydrocarbons and 33.79 trillion cubic meters of natural gas.
The NIOC is exclusively responsible for the exploration, extraction, transportation and exportation of crude oil, as well as sales of natural gas and liquefied natural gas (LNG) in Iran.
Speaking recently, Iran’s petroleum minister Bijan Zangeneh, said production from oil fields in West Karoun region in western Iran is planned to reach 0.7 million barrels a day in its first development phase.
He said of the envisaged 4.7mb/d increase in Iran's crude oil output, 0.7mb/d is expected to be supplied from the region, adding that 16 drilling rigs are operating in South Azadegan field.
West Karoun region is being studied jointly by Petroleum Engineering and Development Company (PEDEC), Arvandan Oil and Gas Company and National Iranian South Oil Company (NISOC).
4. ExxonMobil – 5.3mn barrels per day
The American multi-national oil and gas company is considered the world's largest 'supermajor' and produces around 5.3mn barrels of oil every day.
ExxonMobil's reserves were 25.2bn barrels of oil at the end of 2013, and the organisation operates 37 oil refineries in 21 countries constituting a combined daily refining capacity of 6.3mn barrels.
In the Middle East, ExxonMobil, Abu Dhabi National Oil Company (ADNOC) and Japan Oil Development Company (JODCO), co-venturers in Zakum Development Company (ZADCO), are working together to expand development of one of the world's largest oil fields.
The Upper Zakum field, situated about 50 miles northwest of the city of Abu Dhabi, is currently producing more than half a million barrels a day – a number that could rise to 750,000 barrels oer day.
5. PetroChina – 4.4mn barrels per day
PetroChina is the largest of China's three state-owned or controlled petroleum corporations. The company already produces more oil than ExxonMobil, and according to Forbes magazine, it could someday vie with Gazprom as a regional gas power, considering estimates of its massive shale reserves.
In its annual report, the company said it increased its oil and gas output year on year. In the first quarter of 2015, it pumped 239.4 million barrels of crude, an increase of 3.3% compared with the same period last year.
While China's top oil producer did not mention anything about raising output even further, it vowed to make its operations more efficient and profitable and thus meet its financial targets for 2015.
According to its website, PetroChina is one of the companies with the biggest sales revenue in China and one of the largest oil companies in the world.
6. BP – 4.1mn barrels per day
Another of the world's supermajors, BP produced some 4.1mn barrels of oil per day last year, resulting in revenues of $358.7 billion – more than $1bn a day.
In Abu Dhabi, BP's interests include joint venture partnerships with Abu Dhabi National Oil Company (ADNOC) and shareholdings in the Abu Dhabi Marine Operating Company (BP share 14.67%), , Abu Dhabi Gas Liquefaction Limited (10%), the Natural Gas Shipping Company (10%), and Bunduq Company Limited (3%).
BP also seconds experts to ADNOC and the operating companies, providing technical and managerial support.
It also has a long history in Iraq, dating back to the 1920s. In 2009, BP became the first International Oil Company to come back to Iraq after a period of 35 years. Between 2003 and 2006, BP had conducted a technical evaluation of the Rumaila field with the Ministry of Oil and in 2009 BP and PetroChina were awarded a Technical Service Contract to increase production at Rumaila in partnership with the South Oil Company (SOC). Today, BP, PetroChina and SOC are working in partnership to develop Rumaila, the second largest field in the world estimated to have around 20 billion barrels of recoverable oil remaining.
BP is now also working with the North Oil Company (NOC) on the redevelopment of the Kirkuk field having signed an agreement in September 2013 to provide technical assistance. Kiruk is estimated to have around 9 billion barrels of recoverable oil remaining.
7. Royal Dutch Shell - 3.9mn barrels of oil per day
Publicity around Shell has hardly been positive in 2015. Following the oil price rout, the company had to make thousands of job cuts, shelve a multibillion dollar project in Qatar and settle for lower profits than the year before.
Yet, Shell remains one of the companies in the world with the highest daily output. Its 2014 production, the company said, stood at 3.9mn barrels of oil per day (bopd) and it is already coming close to that number, with 2.9mn bopd in the first half of 2015. It is worth noting, however, that for the same period last year, the English-Dutch energy giant had pumped some 3.1mn.
Last year, the company launched a number of field start-ups, while ramping up production from existing assets, including fields in Nigeria, Malaysia and the Gulf of Mexico, which are expected to contribute some 126, 000 bopd to its output for the second quarter of 2015.
8. Pemex - 3.6mn barrels per day
Mexico is the ninth largest producer of oil in the world and the third largest in the western hemisphere, including the western portions of Europe and Africa, after the United States and Canada. At the beginning of 2002 the country had an estimated 30.8 billion barrels of proven oil reserves, the second largest in the western hemisphere.
However, its annual oil production in 2015 is expected to be the lowest on record as its state-owned company scrambles to recover from falling oil prices, drop in exports and reduced rig count.
Historically, Petróleos Mexicanos, or Pemex, has enjoyed high crude oil output, but in 2014 its production stood at just 2.43mn bpd, marking a 10th consecutive annual output decline.
In fact, the Mexican oil giant's production has dipped more than 30% since hitting peak output of 3.38 million bpd in 2004.
And though the company's oil production and exports rose slightly in February this year, the Pemex said it expects output to be 2.28 million bpd by the end of 2015, down from a previous forecast of 2.40 million bpd.
On the plus side, Pemex recently made one of its biggest discoveries in years. The company said it found new shallow water oil fields in the Gulf of Mexico that could produce 200,000 barrels per day (bpd) by mid-2018.
The total output potential of the fields could be as high as 350 million barrels of crude-oil equivalent, according to the company CEO Emilio Lozoya.
The new fields comprise three of light crude and one of heavy crude, and could come on stream in 16 months, Pemex said.
9. Chevron - 3.5mn barrels per day
Chevron is the third-largest oil company by market value and ranks 9th in terms of daily oil output.
In 2014, the company's worldwide net oil-equivalent production averaged 2.5mn barrels per day, with about 26% of that coming from the United States and the rest from more than 20 other countries.
Headquartered in San Ramon, California, Chevron is active in more than 180 countries globally. It is engaged in every aspect of oil and gas, spanning from exploration and production to refining, chemicals manufacturing and power generation.
Chevron has actively been involved in the Middle East since the 1930s, when it made first oil discovery in Bahrain. Through its subsidiary, Saudi Arabian Chevron (SAC), the company is leading a $340mn steam injection project aimed at boosting production from Saudi Arabia's Wafra field.
10. Kuwait Petroleum Corporation – 3.2mn barrels per day
Kuwait's National Oil Company produced some 3.2mn barrels of oil per day last year, sneaking the organisation into the top 10. In future years, the NOC may finish higher up the list, as it plans to increase production to 4mn barrels per day by 2020
