Oil prices rose on Friday but were headed for their first weekly loss in three weeks as worries about inflation and China's Covidlockdowns slowing global growth offset concerns about dwindling supplies from Russia.
Brent crude futures were up $2.06, or 1.9%, at $109.51 a barrel at 1100 GMT, while US West Texas Intermediate (WTI) crude futures climbed $2.10, or 2%, to $108.23 a barrel.
Both benchmark contracts were, however, on track to post declines for the week, with Brent set to drop 3% and WTI almost 2%.
The market is continuing to be pushed and pulled by the prospect of a European Union ban on Russian oil tightening supply and concerns about faltering global demand.
SPI Asset Management managing partner Stephen Innes said in a note that oil traders were looking "for a glimmer of light at the end of China's gloomy lockdown tunnel".
"Still, we continuously end up at square one with lower case counts weighted against the authorities doubling down on their zero Covidpolicy," he added.
Inflation and rate rises have driven the US dollar to 20-year highs, capping oil price gains as a stronger dollar makes oil more expensive when purchased in other currencies.
Analysts, however, continue to focus on the prospect of a European Union ban on Russian oil, after Moscow imposed sanctions this week on European units of state-owned Gazprom and after Ukraine halted a key gas transit route.
"With European natural gas prices soaring, it is inevitable that some spillover into oil will occur," OANDA senior market analyst Jeffrey Halley said in a note
"An escalation by Russia on the sanctions front is likely to flow into oil price strength," he added.
An International Energy Agency report on Thursday said rising oil production in the Middle East and the United States and a slowdown in demand growth were "expected to fend off an acute supply deficit amid a worsening Russian supply disruption".
