Not quite:

There are 6 "Supermajor" Oil companies around and Half of them are American
Exxon-Mobil = American
Conoco = American
Chevron = American

BP = British Petroleum = British
Shell = Royal Dutch Shell = Dutch
Total = French

Of course in reality they're all multinational corporations and whether they're American, French, Brittsh, or Dutch is just a matter of where their head offices happen to be.
