LONDON: Oil prices rose on Thursday amid concerns about supply as the European Union (EU) mulls a potential ban on Russian oil imports while the market continues to deal with reduced supplies from Libya.

Brent crude futures rose $1.36, or 1.3%, to $108.16 a barrel at 11:11 a.m. ET (1511 GMT). U.S. West Texas Intermediate (WTI) crude futures gained $1.61, or 1.6%, to $103.80 a barrel.

Analysts said market volatility is likely to pick up again soon, with the EU still weighing a ban on Russian oil for its invasion of Ukraine, which Moscow calls a "special military operation" to demilitarise its neighbour.

Libya said the OPEC member was losing more than 550,000 barrels per day of oil output due to blockades at major fields and export terminals.

Oil rebounds as supply concerns dominate

The oil market remains tight with the Organization of the Petroleum Exporting Countries and allies led by Russia, together called OPEC+, struggling to meet their production targets and with U.S. crude stockpiles down sharply in the week ended April 15.

"Global supply capacity for oil remains limited," UBS said in a note.

"With only two countries in the OPEC+ alliance holding significant spare capacity, Saudi Arabia and the UAE, the group is sticking to a cautious approach in unwinding pandemic-related production cuts."

The demand outlook in China continues to weigh on the market, as the world's biggest oil importer slowly eases strict COVID-19 curbs that have hit manufacturing activity and global supply chains.

Meanwhile, the Caspian Pipeline Consortium's Black Sea terminal could return to full capacity this week, Kazakh Energy Minister Bolat Akchulakov said.

"The resumption of CPC crude deliveries will be somewhat offset by continuing outages in Libya and the likelihood of more Russian crude getting locked out of the market in the face of an EU ban," said Vandana Hari, founder of oil market analysis provider Vanda Insights.
