Oil prices regained strength on Friday and are on track for a sixth straight week of gains.
In the European session, Brent crude oil futures traded up 0.4% to $85.55 a barrel, while US WTI firmed at $81.97 a barrel following a 0.3% rise.
Benchmark Brent oil has risen 15.4% and US WTI by 18.2% over the past six weeks.
On Thursday, Saudi Arabia and Russia continued to commit to measures to reduce their production to restore price balance.
Saudi Arabia maintained its production cut of 1 million barrels per day, while Russia will reduce oil exports by 300,000 barrels per day until September.
While OPEC and its allies, OPEC+, have yet to decide whether to cut output, analysts say statements by Saudi Arabia and Russia ahead of the meeting have raised supply concerns.
This provided support for oil prices to rebound after the decline recorded on Wednesday.
