Seven Sisters & Standard Oil

The original Seven Sisters were
Exxon (or Esso, Humble, Standard of NJ), was Rockefeller's Standard Oil Co
Shell,
BP (British Petroleum, originally Burmah Oil + Anglo-Iranian), privatized since 1979
Gulf (was owned by Mellons until sold to Chevron),
Texaco,
Mobil (Standard of NY, or Socony-Vacuum), and
Chevron (Standard of California).


Since Gulf Oil no longer exists (acquired by Chevron in 1984) except as Gulf Canada and a marketing company in the northeast US, Amoco (Standard of Indiana) was often added to the list of six; but in 1998, Amoco was acquired by BP to form BP Amoco, while Exxon was acquiring Mobil; and Chevron and Texaco merged in 2001-2002.
