Brent crude futures ended down $0.80 or 1.16% at $68.23 a barrel.
Data released by Energy Information Administration (EIA) showed crude inventories dropped by 3.2 million barrels in the week ended August 13. Analysts had expected an inventory draw of 1.26 million barrels for the period.

The American Petroleum Institute (API) reported late Tuesday a draw of just over 1 million barrels in U.S. crude supplies for the week ending Aug. 13.
The API data also reportedly showed an inventory decline of 1.2 million barrels for gasoline, while distillate supplies edged up by 502,000 barrels.
U.S. shale oil production is expected to rise to 8.1 million barrels per day (bpd) in September, the highest since April 2020, according to the Energy Information Administration's monthly drilling output report.
