Oil prices edged up in Asian trading on Thursday after Saudi Arabia's state oil company sharply raised March oil prices, but the increase was barely a blip on the biggest slide in benchmark Brent prices in nearly three months the previous day.
Brent crude futures rose 15 cents to $74.76 a barrel by 0740 GMT. U.S. West Texas Intermediate crude was up 20 cents to $71.23 a barrel.
