FILE - In this Thursday, Jan. 28, 2010 file photo, a worker walks past tanks at a Petrochina storage base in Suining, in southwest China's Sichuan province. A big shift is happening in Big Oil: an American giant now ranks second to a Chinese upstart. Exxon Mobil is pumping less oil than PetroChina, a company formed just 13 years ago by the Chinese government to better compete for the world's oil and natural gas. On March 29, 2012, the shift is expected to become official when the Beijing company announces that it produced more crude last year than its 130-year-old Texas rival.
