Oil prices rose on Tuesday as worries about tight fuel supplies ahead of winter offset investor concerns about falling demand in China, the world's biggest crude importer.
Brent crude gained 78 cents, or 0.8%, to $94.78 a barrel by 1030 GMT, while WTI crude rose 79 cents, or 0.9%, to $88.57 a barrel. Both contracts fell by more than $1 earlier in the session.
Worries over tighter inventories continue to support prices.
"The oil market's structural outlook remains on of tightness, but for now, this is offset by cyclical demand headwinds," Morgan Stanley said in a note.
In the United States, the Strategic Petroleum Reserve (SPR) fell 8.4 million barrels to 434.1 million barrels in the week ended Sept. 9, the lowest since October 1984, according to data released on Monday by the Department of Energy.
U.S. President Joe Biden in March set a plan to release 1 million barrels per day over six months from the SPR to tackle high U.S. fuel prices, which have contributed to inflation.
U.S. commercial oil stocks are expected to have fallen for five weeks in a row, dropping by around 200,000 barrels in the week to Sept. 9, a preliminary Reuters poll showed on Monday.
The American Petroleum Institute (API), an industry group, will issue its inventory report at 4:30 p.m. EDT (2030 GMT) on Tuesday. The U.S. Energy Information Administration (EIA) reports at 10:30 a.m. EDT (1430 GMT) on Wednesday.
"We remain constructive on oil prices despite intensifying headwinds to demand, as the supply side remains supportive with slower-than-expected U.S. output growth and a proactive OPEC+," Amarpreet Singh, an energy analyst at Barclays, wrote a note.
Prospects for a revival of the West's nuclear deal with Iran remained dim. Germany expressed regret on Monday that Tehran had not responded positively to European proposals to revive the 2015 agreement. U.S. Secretary of State Antony Blinken said that an agreement would be unlikely in the near term.
Capping gains on oil prices on Tuesday were renewed concerns about lower global fuel demand as China, the world's second-largest oil consumer, continues to impose COVID-19 curbs.
The number of trips taken over China's three-day Mid-Autumn Festival holiday shrank, with tourism revenue also falling, official data showed, as COVID-linked restrictions discouraged people from travelling.
