Oil prices were little changed Tuesday as investors considered comments from officials in the Organization of the Petroleum Exporting Countries.

Front-month West Texas Intermediate oil futures traded up 14 cents, or 0.3%, to $45.29 a barrel on the New York Mercantile Exchange.

Brent crude for February delivery gained 16 cents, 0.3%, at $48.33 a barrel on London's ICE Futures exchange.

On Monday, OPEC's secretary-general, Abdalla Salem el-Badri, said that oil prices appear to have bottomed out and could be poised for a rebound. But Mr. el-Badri also said that OPEC intends to stick to its decision to keep output stable.

On Tuesday, Saudi Aramco, the state-owned oil company, said it would postpone some projects. Its CEO emphasized Saudi Arabia "will not single-handedly balance the market in a downturn," according to news reports.

While some of the comments seem bearish, they may represent a change of tone, Simmons & Co. International said Tuesday in a research note. It is "tough to draw strong conclusions," but this could be a sign that Saudi Arabia is at least willing to join a coordinated response with other producers, something it had adamantly opposed, it said.

"A lot more guys are saying these guys are going to capitulate soon. I don't necessarily think that's true," said Kyle Cooper, managing director of research at IAF Advisors, a Houston consulting firm. "But there definitely is an internal battle going on."

Crude-oil prices have tumbled since midsummer and again in the fall after OPEC decided at its November meeting not to cut its output despite a combination of a global supply glut and lackluster demand.

"We will review [the market at a scheduled meeting] in June and see what we will do," Mr. el-Badri said. "You need at least six months to see the impact."

In the short term, a rebound in prices, which have fallen around 55% since last summer, seems unlikely, analysts say.

The oil market looks fundamentally weak despite initial signs that oil prices may be stabilizing around $47 to $51 a barrel, analysts at Energy Aspects said. "Inventories are building and on top of a high base which will continue to weigh on the term structure of Brent and WTI," Energy Aspects said.

Estimating that the 93 million barrels a day global oil market is currently oversupplied by 1.3 million barrels a day, UBS cut its forecast for the average Brent price this year to $52.50 a barrel from $69.75, and for WTI to $49 a barrel from $64.75.

The bank expects prices to take as long as 60 months to recover to pre-collapse levels. As the "process of correction is clearly under way with significant cuts to capital expenditure already being announced," the bank sees both contracts rebounding to over $60 a barrel next year, with Brent reaching an average price of $90 a barrel by 2018.

Nymex reformulated gasoline blendstock for February, the benchmark gasoline contract, fell 0.8% to $1.3061 a gallon.

February diesel lost 1.72 cents, or 1.1%, to $1.6226 a gallon.
