Seven Sisters (oil companies)

The Seven Sisters of the petroleum industry is a term coined by an Italian 
entrepreneur, Enrico Mattei,[1] that refers to seven oil companies that 
dominated mid 
20th century oil production, refining, and distribution.Origin and makeup The 
Seven Sisters consisted of three companies formed by the breakup by the U.S. 
Government of Standard Oil, along with four other major oil companies. With 
their dominance of oil production, refinement and distribution, they were able 
to take 
advantage of the rapidly increasing demand for oil and turn immense profits.

Being well organized and able to negotiate as a cartel, the Seven Sisters were 
able to have their way with most Third World oil producers. It was only when 
the 
Arab states began to gain control over oil prices and production, mainly 
through the formation of OPEC, beginning in 1960 and really gaining power by 
the 1970s, 
that the Seven Sisters' influence declined.

The Seven Sisters were the following companies:

Standard Oil of New Jersey (Esso), which merged with Mobil to form ExxonMobil. 

Royal Dutch Shell (Dutch / British) 

Anglo-Persian Oil Company (APOC) (British). This later became Anglo-Iranian Oil 
Company (AIOC), then British Petroleum, and then BP Amoco following a 
merger with Amoco (which in turn was formerly Standard Oil of Indiana). It is 
now known solely by the initials BP. 

Standard Oil Co. of New York ("Socony"). This later became Mobil, which merged 
with Exxon to form ExxonMobil. 

Standard Oil of California ("Socal"). This became Chevron, then, upon merging 
with Texaco, ChevronTexaco. It has since dropped the 'Texaco' suffix, returning 
to 
Chevron. 

Gulf Oil. In 1985, most of Gulf became part of Chevron, with smaller parts 
becoming part of BP and Cumberland Farms, in what was, at that time, the 
largest 
merger in world history. A network of stations in the northeastern United 
States still bears this name. 

Texaco. Merged with Chevron in 2001. The merged company was known for a time as 
ChevronTexaco, but in 2005, changed its name back to Chevron. Texaco 
remains a Chevron brand name. 

As of 2005, the surviving companies are ExxonMobil, Chevron, Royal Dutch Shell, 
and BP, now members of the "supermajors" group.

 The "New Seven Sisters"

On 11 March 2007, the Financial Times identified the "New Seven Sisters", the 
most influential and mainly state-owned national oil and gas companies from 
countries outside the OECD. They are:

Saudi Aramco (Saudi Arabia) 

JSC Gazprom (Russia) 

CNPC (China) 

NIOC (Iran) 

PDVSA (Venezuela)
 
Petrobras (Brazil) 

Petronas (Malaysia)
