Oil continued its course of gains on Friday and geared towards hitting gains for the second consecutive week, buoyed by the ongoing geopolitical disruptions, worries over capped supply and bolstered hopes on global demand.

Brent crude soared by 0.7% to $91.24 per barrel, while US WTI added 0.5% at $87.02 per barrel.

Brent and WTI are poised to hit over 4% gain this week, advancing for the second consecutive week, following Iran, the third-largest OPEC producer, promised retaliation against Israel following an attack that claimed the lives of senior Iranian military officers.

According to a NATO officer on Thursday, Russia's gasoline output may have been affected by ongoing Ukrainian drone attacks on its refineries, which may have interrupted over 15% of Russia's capacity.

This week, OPEC and its allies—known as OPEC+—under the leadership of Russia maintained its policy on oil supply while applying pressure on certain nations to tighten their adherence to output reductions.
