Seoul: Oil prices dipped slightly on Friday as the U.S. dollar edged up from its overnight lows, while forecast higher production by U.S. shale oil producers this year added to lingering worries over demand.
U.S. crude futures for July shed 7 cents to $60.38 a barrel as of 0009 GMT after closing up 53 cents in the previous session.
Brent crude for August fell 14 cents to $64.12 a barrel, having settled up 39 cents on Thursday.
A firmer U.S. dollar makes oil futures more expensive for holders of other currencies, while the potential for increased imports to the United States could also pressure U.S. oil prices.
"The narrowing of the Brent/WTI spread is improving the economics of imports rather than domestic purchases," ANZ said on Friday. It noted U.S. rail volumes of crude oil and petroleum dropped 12 per cent year on year last week as higher imports slow purchases from regions such as North Dakota.
U.S. shale oil producers have projected a rise in output for the year even as they have scaled back drilling to cope with a near 45 per cent slump in crude prices.
