2. Exxon Mobil Corporation

Exxon Mobil Corporation remains in second place this year. The large integrated company has capacity approaching 1.9 million bbl/cd.

Marathon’s acquistion of the Texas City refinery from BP catapults it into third place in the US refinery ranks. Marathon now has capacity of 1.7 million bbl/cd.
