Oil prices rose on Thursday, extending gains from the previous session, as an industry report showing a fall in US crude stockpiles last week added to positive comments by the US Federal Reserve head on the US economy.
US West Texas Intermediate crude CLc1 was up 20 cents, or 0.4%, at $57.32 a barrel by 0111 GMT, after rising 0.6% on Wednesday.
Brent futures LCOc1 were up 17 cents, or 0.3% at $62.54 a barrel, having risen 0.5% in the previous session.
Federal Reserve Chair Jerome Powell said on Wednesday the US economy would see a "sustained expansion" with the full impact of recent interest rate cuts still to be felt, boosting hopes for increased demand for crude.
Powell's "rosy view of the US economy reinforces the view that the Fed sees the economy is on a positive track," said Stephen Innes, chief Asia market strategist at AxiTrader.
US crude inventories fell by 541,000 barrels in the week to November 8 to 440 million, data from the American Petroleum Institute, an industry group, showed on Wednesday, compared with analysts' expectations for an increase of 1.6 million barrels.
Official data from the US Energy Information Administration is due at 11:00 a.m. EST (1600 GMT) on Thursday. Both reports were delayed a day for the US Veterans Day holiday on Monday.
Concerns have eased over a US recession, although an economic rebound is also not expected any time soon, according to a Reuters poll of economists released on Thursday.
The poll also showed that economists believe the US-China trade war is unlikely to see a permanent truce over the coming year, which may further impact global growth and demand for oil, putting a cap on prices.
Still, OPEC Secretary General Mohammad Barkindo said global economic fundamentals remained strong and that he remained confident the United States and China would reach a trade deal.
The Organization of the Petroleum Exporting Countries (OPEC) and other producers including Russia - grouping known as OPEC+ - have been restraining production since January to try support oil prices.
