Saudi Aramco (the Saudi Arabian Oil Company) is the world’s largest
petroleum business. However, it never appears in the rankings of the
world’s largest oil producers, since it
does not publish financial information such as profit, sales, assets, or
market capitalization. Therefore America’s ExxonMobil and Chevron,
China’s Sinopec and PetroChina, the Anglo-Dutch company Royal Dutch
Shell, Great Britain’s BP, and France’s Total top the rankings. But
everyone knows perfectly well that these leaders in the global oil
industry are mere dwarfs compared to Saudi Aramco.
