Unused gas burns out of a flare bleeder in Petrochina's Tazhong oil factory, in Tarim Oilfield, Xinjiang province, China, on October 12, 2006. PetroChina went public on the Shanghai Stock Exchange Monday, Nov. 5, and the shares nearly tripled the same day. At US$1.005 trillion market capital, PetroChina is now the only trillion-dollar company in the world, twice the value of its US peer Exxon Mobil. Photo by Servais Mont/Pictobank
