Global benchmark Brent crude futures fell 21 cents, or 0.2%, to $100.01 a barrel by 0114 GMT, after rising 3.9% on Tuesday. The U.S. West Texas Intermediate crude futures contract was down 10 cents, or 0.1%, at $93.64 a barrel, having jumped 3.7% the previous day.
Both contracts soared on Tuesday after de facto OPEC leader Saudi Arabia flagged the possibility of introducing cuts to balance a market it described as "schizophrenic", with the paper and physical markets becoming increasingly disconnected.
