The global oil and gas industry is in the midst of one of the severest downturns in 30 years, as the perfect storm of overproduction and geopolitical tensions have seen oil prices plunge.

However, the fact remains that the industry has produced some of the largest companies in known history.

Our list of the top 10 oil and gas companies in the world by revenue

10. OJSC Lukoil

Revenue (2014): $144.17 billion
Country of Origin: Russia
Founded: 1991
Employees: 150,000

Lukoil was formed when three Russian state-run west Siberian companies, Langepasneftegaz, Urayneftegaz, and Kogalymneftegaz, merged in 1991. Prior to Lukoil’s formation, the three companies performed exploration, refining, and distribution seperately. However, President Vagit Alekperov believed the only way for the post-Soviet Russian firms to succeed against their Western competitors would be to copy their business models, causing him to bring the three branches together.

Today, Lukoil is one of a few large private oil companies based in Russia. In terms of proven oil and gas reserves, it is second only to ExxonMobil and controls 1.3% of the global reserves.

9. Chevron Corporation

Although Standard Oil bought out the company in 1900, the breakup of Standard Oil saw it reborn as Standard Oil Co. of California. It secured a 50-year concession with Saudi Aramco. In 1984, the company merged with Gulf Oil in what was the largest merger in history at that time, and Chevron Corporation was born.

During the mid-1940s to the 1970s, Chevron was one of the Seven Sisters, a collection of seven global oil companies that completely dominated the global petroleum industry. Today, Chevron has developed interests in alternative energy sources, and it claims to be the world’s largest producer of geothermal energy.

At its inception, the company benefitted from a 25% share of the Turkish Petroleum Company that France received from Germany as reparations for WWI.
Total has ventured into alternate energy beginning with its foray into solar in 1975, followed by nuclear energy in 2011. At the end of 2013, Total had a total of 898 subsidiaries all over the world, and ranked #10 on Forbes Global 500.

But soon he struck gold when British geologists discovered a large oil reserve in 1908. Upon the discovery, the Shah of Iran agreed to give D’Arcy the oil rights to most of the country in exchange for 16% of the oil company’s annual profits. The consequences of this deal would haunt the Iranians up until the late 20th century.

BP manages operations in 30 countries around the world, with its U.S. operations alone making up a third of its revenue. The company’s UK branch controls more than 40 offshore oil and gas fields, four onshore terminals, and a pipeline network that transfers 50% of the gas and oil produced in the UK.
