Wait a minute...
Of the global oil giants, Exxon Mobil has the biggest proven reserves -- 11.2 billion barrels, according to Energy Intelligence Research.
But that makes the company only No. 12 in the world. And every company ahead of it in the rankings is an oil company controlled by a national government. That includes Russia's Gazprom (OGZPY, news, msgs) and Lukoil (LUKOY, news, msgs) at No. 9 and No. 10 with 19 billion and 16 billion barrels, respectively, Venezuela's PDVSA at No. 5 with 77 billion barrels, and Iran's NOIC at No. 2 with 133 billion barrels. (Saudi Arabia's Aramco is No. 1 with 263 billion barrels of proven reserves.)
Looks like Collin Campbells recommendation to nationalize the oil companies is reality.
