Oil edge up in volatile trade on U.S. crude build, Russian OPEC support

By Scott DiSavino NEW YORK (Reuters) - Oil prices edged higher in volatile trading as the market weighed Russia's comments about a possible meeting with Saudi Arabia on possible output cuts against a bigger-than-expected U.S. crude storage build. U.S. crude rose 32 cents, or 0.7 percent, to $46.13 per barrel. Before the U.S. Energy Information Administration released its petroleum status report, both contracts were down less than 1 percent.
