Dubai crude oil quoted by price-reporting agency Platts averaged $108.708 a barrel for March, traders said on Monday.
That was higher than February, when Dubai crude averaged $100.239 a barrel.
The average is used as the basis for the Abu Dhabi and Qatari retroactive March official selling prices (OSPs), which are set as differentials to Dubai.
Oman crude oil quoted by Platts averaged $108.997 a barrel for March, up from $100.597 in February, traders said. That would put the March Oman/Dubai average at $108.85.
