Brent crude was up 32 cents, or 0.42%, to $77.37 a barrel at 0135 GMT. U.S. West Texas Intermediate crude rose 42 cents, or 0.57%, to $74.67.
Oil output from the Organization of the Petroleum Exporting Countries fell in December after two months of increase. Field maintenance in the United Arab Emirates offset a Nigerian output hike and gains elsewhere in the group.
In Russia, oil output averaged 8.971 million barrels a day in December, below the country's target.
On the economic front, job openings rose in the United States in November and the number of layoffs was low, while workers were reluctant to quit, the Job Openings and Labor Turnover Survey showed. Oil prices rise with economic growth.
"The November JOLTS data, when paired with recent employment reports, shows a labour market returning to pre-pandemic norms," Capital Economics said in a client note.
Elsewhere in the U.S., crude oil stocks fell last week while fuel inventories rose, market sources said, citing American Petroleum Institute figures on Tuesday.
Going forward, analysts expect oil prices to be on average down this year from 2024 due in part to production increases from non-OPEC countries.
"We are holding to our forecast for Brent crude to average $76/bbl in 2025, down from an average of $80/bbl in 2024," BMI, a division of Fitch Group, said in a client note.
"The bearish view is being led by our fundamental data forecast, which points to an oversupply this year, with supply growth outstripping demand growth by 485,000 barrels per day."
