Brent crude futures were up $3.10, or 2.8%, at $114.24 a barrel at 0419 GMT after trading in a more than $5 range. The benchmark contract slumped 13% in the previous session in its biggest one-day drop in nearly two years.
U.S. West Texas Intermediate (WTI) crude futures were up $1.58, or 1.5%, at $110.28 a barrel, after trading in a more than $4 range. The contract had tumbled 12.5% in the previous session in the biggest daily decline since November.
Uncertainty over where and when supply will come from to replace crude from the world's second largest exporter Russia in a tight market has led to wide ranging forecasts for oil prices between $100 and $200 a barrel.
"So to suggest the oil market is confused would be an understatement as we are in an unprecedented situation," said Stephen Innes, managing partner at SPI Asset Management.
Comments from the United Arab Emirates energy minister and the country's ambassador to Washington sent conflicting signals.
UAE Energy Minister Suhail al-Mazrouei said on Twitter late on Wednesday his country is committed to the existing agreement by the Organization of the Petroleum Exporting Countries and allies including Russia, together called OPEC+, to ramp up oil supply by 400,000 barrels per day monthly following sharp cuts in 2020.
"The UAE believes in the value OPEC+ brings to the oil market," al-Mazrouei said.
Just hours before, prices slumped on comments from UAE's ambassador to Washington saying his country will be encouraging OPEC to consider higher output to fill the supply gap due to sanctions on Russia.
The comments from UAE officials came as the market also took into account moves by the United States to ease sanctions on Venezuelan oil and efforts to seal a nuclear deal with Tehran, which could lead to more oil supply coming from Iran later this year.
Talks set for Thursday between Russia and Ukraine's foreign ministers in Turkey also gave the market reason for pause.
While UAE and Saudi Arabia have spare capacity, some other OPEC+ producers are struggling to meet their output targets due to underinvestment in infrastructure over the past few years, which will limit their ability to lift output further.
"We think it will be challenging for OPEC+ to boost production in this environment," Commonwealth Bank commodities analyst Vivek Dhar said.
However Standard Chartered analysts predicted OPEC would look to fill the Russian supply gap, "effectively ending the OPEC+ agreement in its current form".
