Oil prices were set for a second straight week of decline on Friday after Libyan ports reopened and on the view that Iran might still export some crude despite U.S. sanctions.
Brent crude LCOc1 was down 10 cents at $74.35 per barrel by 1308 GMT, having fallen earlier by 1.3 percent. It was heading for a weekly fall of around 3 percent.
U.S. benchmark West Texas Intermediate crude CLc1 was up 10 cents at $70.43, and was on course for a weekly decline of around 4 percent.
Oil approached $80 in late June and early July due to Libyan and Venezuelan supply disruptions and fears the United States would press all buyers of Iranian oil to cut imports to zero from November.
But prices weakened in recent days as OPEC member Libya reopened its ports in the east and U.S. Secretary of State Mike Pompeo said Washington would consider granting waivers to some of Iran’s crude buyers.
