The amount of oil held in U.S. storage tanks rose by 4.6 million barrels last week after Hurricane Harvey added to the glut that has kept crude prices low for more than three years.
That brought U.S. crude inventories up to 462.4 million barrels.
Crude imports fell by 822,000 barrels per day to 7.1 million barrels per day.
The nation’s stockpile of gasoline declined by 3.2 million barrels as U.S. buyers scrambled for fuel supplies and more than a dozen major refineries were knocked offline.
All told, commercial petroleum inventories rose by 7 million barrels in the week ended Sept. 1, the Energy Department said in its weekly report on Thursday.
