TOKYO (Reuters) - Oil prices eased on Friday and were heading for a third weekly loss after Saudi Arabia's OPEC governor said the market could be heading into oversupply, as growth concerns took a hit with a slump in global equities this week.

Saudi Arabia's OPEC governor said on Thursday the oil market could face oversupply in the fourth quarter.
"The market in the fourth quarter could be shifting towards an oversupply situation as evidenced by rising inventories over the past few weeks," Adeeb Al-Aama told Reuters.
Saudi Arabia Energy Minister Khalid Al-Falih said there could be a need for intervention to reduce oil stockpiles after increases in recent months.

Financial markets have been hit hard by a range of worries, including the U.S.-China trade war, a rout in emerging market currencies, rising borrowing costs and bond yields, as well as economic concerns in Italy.
U.S. crude oil stockpiles rose last week for the fifth consecutive week, while gasoline and distillate inventories fell, the Energy Information Administration said this week.
Supporting the bearish mood was a report that showed rising inventories at Cushing, Oklahoma, the delivery hub for U.S. crude futures.
Cushing crude stocks rose to 33 million barrels on Tuesday, up almost 1.8 million barrels from the previous week, traders said, citing a report by market intelligence firm Genscape.
