Big Oil

Globally, net income of the oil and gas industry reached a record US$4 trillion in 2022.

After the COVID-19 pandemic, energy company profits increased with higher fuel prices resulting from the Russian invasion of Ukraine, falling debt levels, tax write-downs of projects shut down in Russia, and backing off from earlier plans to reduce greenhouse gas emissions.

Big Oil is a colloquial grouping of the world's six or seven largest publicly traded and investor-owned oil and gas companies, also known as supermajors.


Oil major	Revenue 2024 (USD$)	Profits 2024 (USD$)
Exxon Mobil	339.25 billion	48.87 billion
Shell	284.31 billion	16.5 billion
TotalEnergies	195.61 billion	29.82 billion
Chevron	193.41 billion	28.10 billion
BP	189.19 billion	11.47 billion
Eni	140.0 billion	21.0 billion

The term, particularly in the United States, emphasizes their economic power and influence on politics. Big Oil is often associated with the fossil fuels lobby and also used to refer to the industry as a whole in a pejorative or derogatory manner.

Sources conflict on the exact makeup of Big Oil today, though the companies which are most frequently mentioned as supermajors are ExxonMobil, Shell, TotalEnergies, BP, and Chevron with Eni and ConocoPhillips, prior to ConocoPhillips spinning off its downstream operations into Phillips 66, frequently being included as well. The phrase "Super-Major" emanated from a report published by Douglas Terreson of investment bank Morgan Stanley in February 1998. The report predicted a substantial consolidation phase of "Major" Oil companies which would result in a group of dominant "Super-Major" entities. Big Oil previously referred to seven oil companies which formed the Consortium for Iran; such "Seven Sisters" were the Anglo-Persian Oil Company (a predecessor of BP), Shell plc, three of Chevron's predecessors (Standard Oil of California, Gulf Oil and Texaco), and two of ExxonMobil's predecessors (Jersey Standard and Standard Oil of New York).

The term, analogous to others such as Big Tech, Big Steel, Big Tobacco, Big Soda, and Big Pharma which describe industries dominated by a few giant corporations, was popularized in print from the late 1960s. Today it is often used to refer specifically to the seven supermajors. The use of the term in the popular media often excludes the national producers and OPEC oil companies who have a much greater global role in setting prices than the supermajors. China's two state-owned oil companies, Sinopec and the China National Petroleum Corporation, as well as Saudi Aramco, had greater revenues in 2022 than any investor-owned oil company.

In the maritime industry, six to seven large oil companies that decide a majority of the crude oil tanker chartering business are called "Oil Majors".
