CORRECTS TO RANKS BEHIND, NOT RANKS SECOND - In this photo taken Friday March 16, 2012 and made available March 26, 2012, oil rigs belonging to PetroChina are seen near the banks of a snow covered lake in Daqing in northeastern China's Heilongjiang province. A big shift is happening in Big Oil: an American giant now ranks behind 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. (AP Photo) CHINA OUT less
