Oil prices gained on Friday after Saudi Arabia's OPEC governor said the kingdom's exports are likely to fall next month and inventories may be squeezed in the third quarter, Reuters reported. Brent oil rose 22 cents, or 0.3 percent, to $72.80 by 0034 GMT, after falling 32 cents on Thursday. US West Texas Intermediate was up 51 cents, or 0.7 percent, at $69.97, extending a 1 percent gain in the previous session, Reuters reported. However, both benchmarks are on track for a third weekly loss, after big falls early in the week.

Saudi Arabia moved on Thursday to allay fears of oversupply. The world's biggest oil exporter expects its crude shipments to drop by roughly 100,000 barrels per day in August as it works to ensure it does not push oil into the market beyond customers' needs, the kingdom's OPEC governor Adeeb Al-Aama said.
