WTI crude futures settled 0.1% higher at $37.33 a barrel on Friday, but notched a second weekly loss of 6.1 per cent.
It was the largest loss since the beginning of June amid a surprise build in US crude oil inventories and mounting concerns over fuel demand recovery.
Data from the EIA showed a rise of 2.032 million barrels in US crude stockpiles in the latest week, in line with the API which reported a build of 3 million barrels.
