Oil prices slipped on Wednesday on expectations for a build-up in U.S. crude inventories, but Russian government comments on prospects for stepping up cooperation with OPEC to coordinate output cuts braked steeper decline.  U.S. WTI crude futures were at $63.36 a barrel at 0208 GMT, down 15 cents, or 0.24 percent, from their previous settlement.  Brent crude futures dipped to $67.94 per barrel, down 18 cents, or 0.26 percent, after it rose 0.7 percent on Tuesday.  U.S. crude inventories likely saw a build for the second straight week, while refined product stockpiles were forecast to have declined last week, an expanded Reuters poll showed on Tuesday.

“With the change in prices being only a few cents, I think the oil market is waiting for the next development and of course the U.S. inventories data due tonight (Wednesday) is very good reason for traders to be waiting,” said Michael McCarthy, Chief Market Strategist at brokerage CMC Markets.  Industry group the American Petroleum Institute, however, said on Tuesday U.S. crude stocks have unexpectedly fallen last week as refineries boosted output.
