Oil prices edged higher on Thursday, extending their 2 per cent gains from the previous session, after data showed US crude stockpiles fell last week, while OPEC and its allies were seen complying with their pact to curb output in September.
US West Texas Intermediate (WTI) crude futures climbed 8 cents, or 0.2 per cent, to $41.12 a barrel at 0430 GMT, while Brent crude futures rose 7 cents, or 0.2 per cent to $43.39 a barrel.
Oil markets climbed for a third day despite a resurgence in Covid-19 infections across Europe potentially denting fuel demand.
"The energy markets are certainly marching to their own drummer at the moment," said Michael McCarthy, chief market strategist at CMC Markets and Stockbroking, adding that recent oil price volatility may have attracted more trader positions.
The American Petroleum Institute industry group said US crude, gasoline and distillate inventories all fell in the week to October 9, according to a report released after market close on Wednesday.
Crude stockpiles fell by 5.4 million barrels, while distillate stockpiles, which include diesel and heating oil, fell by 3.9 million barrels. Those drawdowns were nearly double analysts' expectations in a Reuters poll.
"Much of the fall is due to the effects of Hurricane Delta shuttering US production in the Gulf of Mexico, and as such, will be a transitory effect," said Jeffrey Halley, senior market analyst, Asia Pacific at OANDA.
"Therefore, I am not getting too excited that a turn of direction is upon markets, although both contracts are approaching important technical resistance regions."
