Oil prices rose on Thursday as concerns about supply as the European Union (EU) mulls a potential ban on Russian oil imports, days after diminished supplies from Libya rocked the market.

Brent crude futures rose $1.11, or 1%, to $107.91 a barrel at 0852 GMT. US West Texas Intermediate (WTI) crude futures gained 87 cents, or 0.9%, to 103.06 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".

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

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 US crude stockpiles down sharply in the week ended April 15.

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

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 on Wednesday.

"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.
