Qatar Petroleum raised the official selling prices (OSP) of its marine and land crudes in December, as per a pricing document posted on its website.

Qatar marine was set at a premium of $2.20/barrel over the Dubai/Oman crudes average and Qatar land was priced at a premium of $2.55/barrel over the same benchmark.

In November, the OSP for marine crude was set at a premium of $1.30 and land crude at a premium of $1.35.

Qatar's move comes after Saudi Arabia's state-owned oil producer Aramco raised last week its December official selling price to Asian customers, suggesting strong demand amidst tighter supplies.
