Oil prices rose in early Asian trading hours on Friday as signs of strong summer demand and easing inflationary pressures in the world's biggest oil market, the United States, bolstered investor confidence.

Brent crude futures rose 37 cents, or 0.4%, to $85.77 a barrel by 0031 GMT. U.S. West Texas Intermediate crude futures rose 50 cents, or 0.6%, to $83.12 a barrel.

Both contracts gained in the prior two sessions, but Brent futures were set to decline about 1% week-over-week after four consecutive weeks of gains.

WTI futures were virtually unchanged on a weekly basis.
