Oil futures rose Friday with volatility expected ahead of a meeting later this month of major oil-producing countries aiming to strike a deal to cut output and stabilize prices.

Oil markets have been in a tug of war this week as major oil producers have tried to indicate optimism about an agreement to cut production, even as a strengthening U.S. dollar and data showing an unexpectedly large increase in U.S. oil supplies have weighed on prices.

"I think it's going to be a little bit of a choppy day today," said Tariq Zahir, managing member of Tyche Capital Advisors. "There's a lot of rhetoric out there, but you can't ignore what happened with the inventory numbers, and the dollar is a massive headwind," he said.

West Texas Intermediate futures were up 18 cents, or 0.4%, at $45.60 a barrel on the New York Mercantile Exchange. Brent, the global benchmark, was up 19 cents, of 0.41%, at $46.68 a barrel on London's ICE Futures exchange.

Members of the Organization of the Petroleum Exporting Countries, which controls over a third of the world's oil, are scheduled to meet Nov. 30 to try to agree on output quotas, although it is likely to be a challenging task, with some requesting exemptions.

The market is particularly sensitive to statements coming out of Doha this week, where talks between OPEC members on the sidelines of a gas forum were expected to give some indication of progress toward a deal to cut oil production to between 32.5 million and 33 million barrels a day, from record levels of around 33.83 million barrels a day in October.Saudi Energy Minister Khalid al-Falih told Saudi-owned Al Arabiya television on Thursday that he is "optimistic" that OPEC's members will formalize the tentative deal they reached in September and set production limits for individual countries.

But observers are skeptical about a quick outcome.

"There is a lot of uncertainty on OPEC's ability to reach an outcome," said Peter Lee, Asia oil and gas analyst at BMI Research. "I am personally not optimistic."

The impact of any agreement between OPEC members to lower production could also be offset by surging output from non-OPEC producers, such as Russia, where production hit a post-Soviet high of 11.2 million barrels a day in October.

"Russia has earlier spoken with mixed voices regarding joining OPEC in an output cut or freeze," said Michael Poulsen, oil risk manager at Global Risk Manager.

Oil markets were also under pressure from a strengthening U.S. dollar aftercomments from Federal Reserve Chairwoman Janet Yellen raised expectations that the central bank will raise interest rates next month. A stronger dollar makes oil more expensive in other currencies.

The WSJ Dollar Index was up 0.1% on Friday against a basket of currencies, paring earlier gains, having advanced for nine consecutive trading days, its longest winning run since 2009.

Gasoline futures fell 0.41 cents, or 0.31%, to $1.3389 a gallon. Diesel futures rose 1.54 cents, or 1.06%, to $1.4624 a gallon.
