Oil prices rose on Friday, supported by a dip in Libyan production and upbeat comments from Saudi Arabia that an OPEC-led effort to erode stockpiles is working.
U.S. crude ended Tuesday's session up 78 cents, or 1.2 percent, at $63.55, posting a 3 percent weekly gain.
Brent crude, the global benchmark, was up 56 cents at $66.95 by 1:10 p.m. ET and was on track for a roughly 3 percent gain for the week.
Crude rebounded from an early loss after the shutdown of the El Feel oilfield in Libya, which produces 70,000 barrels per day of crude. Production in the OPEC-member has been running at about 1 million bpd, although it remains volatile due to unrest.
