LONDON (Reuters) - Oil rose on Friday on hopes that supply cuts will be agreed at OPEC's meeting on Dec. 6, but failed to recoup recent losses on oversupply concerns that have shaved more than a fifth off the Brent crude benchmark since early October.
Brent was up 85 cents at $67.47 a barrel by 0929 GMT. It has been recovering for three sessions since hitting an eight-month low on Tuesday but is still on course for a weekly loss of about 4 percent.
U.S. West Texas Intermediate (WTI) futures rose 55 cents to $57.01 a barrel after their steepest one-day loss in more than three years on Tuesday.
With WTI set for a weekly loss of about 5.3 percent, both benchmarks are poised to chalk up their sixth consecutive weekly drop.
"The trend is down - stick with it," PVM technical analyst Robin Bieber said.

Prices were mainly supported by expectations that the Organization of the Petroleum Exporting Countries (OPEC) would start withholding supply soon, fearing a repeat of the 2014 price rout.
Some analysts said an extended rally is possible with support from U.S. sanctions on Iranian oil once current waivers expire, as well as lower Venezuelan production and uncertainly over Libyan output.
"We are likely from December onwards to have at least 1 million barrels a day less of crude exports," Harry Tchilinguirian, global head of commodity markets strategy at BNP Paribas, told the Reuters Global Oil Forum.
Tchilinguirian said he would not be surprised if Brent hit $80 a barrel this year.
OPEC's de facto leader, Saudi Arabia, wants the cartel to cut output by about 1.4 million barrels per day (bpd), around 1.5 percent of global supply, sources told Reuters this week.
The Saudis would ideally have Russia participate but Russia has yet to commit to any renewed joint action.
Morgan Stanley warned that a cut by the Middle East-dominated group might not have the desired effect.
"The main oil price benchmarks - Brent and WTI - are both light-sweet crudes and reflect this glut," the U.S. bank said.
"OPEC production cuts are usually implemented by removing medium and heavier barrels from the market but that does not address the oversupply of light-sweet."
While OPEC considers withholding supply, U.S. crude oil production reached another record last week, at 11.7 million bpd, according to the U.S. Energy Information Administration (EIA).
The record output helped U.S. crude oil stocks to their biggest weekly build in nearly two years.
"Oil bulls, us included, have capitulated and we no longer see oil climbing to $95 a barrel next year," Bank of America Merrill Lynch said in a note.
