Big Oil

The history of the supermajors traces back to the "Seven Sisters", the seven oil companies which formed the "Consortium for Iran" cartel and dominated the global petroleum industry from the mid-1940s to the 1970s.[15][16] The Seven Sisters were:

• Anglo-Persian Oil Company (now BP);
• Gulf Oil, Standard Oil of California (Socal) and Texaco (now Chevron);
• Royal Dutch Shell
• Standard Oil of New Jersey (Esso) and Standard Oil Company of New York (Socony) (now ExxonMobil).

Before the oil crisis of 1973 the members of the Seven Sisters controlled around 85% of the world's oil reserves. The supermajors began to emerge in the late-1990s, in response to a severe fall in oil prices. Large petroleum companies began to merge, often in an effort to improve economies of scale, hedge against oil price volatility, and reduce large cash reserves through reinvestment.[17] The following major mergers and acquisitions of oil and gas companies took place between 1998 and 2002:

• Exxon's merger with Mobil in 1999, forming ExxonMobil;
• Total's merger with Petrofina in 1999 and with Elf Aquitaine in 2000, with the resulting company subsequently renamed Total S.A.;
• BP's acquisitions of Amoco in 1998 and of ARCO in 2000;
• Chevron's acquisition of Texaco in 2001;
• Conoco Inc.’s merger with Phillips Petroleum Company in 2002, forming ConocoPhillips.

This process of consolidation created some of the largest global corporations as defined by the Forbes Global 2000 ranking, and as of 2007 all were within the top 25. Between 2004 and 2007 the profits of the six supermajors totaled US$494.8 billion.[18]

As a group, the supermajors control around 6% of global oil and gas reserves. Conversely, 88% of global oil and gas reserves are controlled by the OPEC cartel and state-owned oil companies, primarily located in the Middle East.[19] A trend of increasing influence of the OPEC cartel, state-owned oil companies[15][20] in emerging-market economies is shown and the Financial Times has used the label "The New Seven Sisters" to refer to a group of what it argues are the most influential national oil and gas companies based in countries outside of the OECD, namely CNPC (China), Gazprom (Russia), National Iranian Oil Company (Iran), Petrobras (Brazil), PDVSA (Venezuela), Petronas (Malaysia), Saudi Aramco (Saudi Arabia).[21][22]

In the maritime industry, a group of six companies that control the chartering of the majority of oil tankers worldwide are together referred to as "Oil Majors".[23] These are: Royal Dutch Shell, BP, ExxonMobil, Chevron, Total and ConocoPhillips.[24][25] Charter parties such as "Shelltime 4" frequently mention the phrase "oil major".[26]
