Crude oil losses continued for a third consecutive session on Wednesday, hours ahead of US inventory data.
WTI fell by 0.9% to $ 63.93 a barrel amid renewed concerns about an increase in crude production in the United States.
Brent crude also lost 0.8% to $ 68.40 after falling by 0.6% yesterday to $ 69.02 a barrel.
The US Petroleum Institute said on Tuesday evening that crude oil supplies in the United States rose by 3.23 million barrels in the week ending on January 26. Gasoline inventories rose by 2.69 million barrels, while distillate inventories fell by 4.1 million barrels.
Last week, oil futures rose to $ 65 a barrel after the International Energy Agency (IEA) reported a 10-week decline in inventories. However, market expectations are in favor of higher inventories of 0.1 million barrels, which will weigh on black gold trading.
