The American Petroleum Institute on Tuesday reported a decrease of 3.069 million barrels of crude oil in U.S. inventories for the week ending Dec. 16.
Analysts expected a drop of 0.167 million barrels for this week.
The institute reported a surge of 7.819 million barrels in the previous week.
Oil prices climbed on Tuesday, finding support from a weaker U.S. dollar.
The West Texas Intermediate for January delivery added 90 cents, or 1.2 percent, to settle at 76.09 U.S. dollars a barrel on the New York Mercantile Exchange. Brent crude for February delivery gained 19 cents, or 0.2 percent, to settle at 79.99 dollars a barrel on the London ICE Futures Exchange.
