Oil futures rose ahead of the end of last week, but remain heading for the biggest weekly loss, on fears that a slower global economic growth would hurt fuel demand, although Saudi Arabia said it had regained full oil production.
Brent crude futures were up 12 cents, or 0.2 percent, at $ 57.83 a barrel, while US West Texas Intermediate crude futures were up 9 cents, or 0.2 percent, at $ 52.54 an ounce.
In a week, Brent fell 6.6%, the largest weekly loss since December 2018.WTI crude also fell 6% since the beginning of last week, the biggest decline since July 2019.
Weak data from the US services sector and job growth on Thursday added to worries about global oil demand and heightened fears that the long-running trade war between the United States and China could push the global economy into recession.
