At the end of the session, benchmark West Texas Intermediate crude was up three cents at US$92.12 a barrel.
Oil had risen as high as US$92.85 per barrel in the morning after gains in European stocks. But then the price dipped after the U.S. government reported a bigger than expected increase in U.S. crude supplies.
Supplies rose by 2.9 million barrels last week. That was almost double what analysts had forecast, according to Platts, the energy information arm of McGraw-Hill Cos.
Gasoline supplies also rose. Analysts had predicted a decline.
Brent crude, which is used to price international varieties of oil, fell 78 cents to US$113.22 a barrel on the ICE Futures exchange in London.
