Nigeria's Nembe Creek pipeline, which brings Bonny Light crude to the coast for export, also reopened over the weekend after being closed on Jan. 17.

"Angolan is a bit stronger, but Nigerian not much," one trader said. "The market is not picking up much compared to last month." While there are only around 10 March-loading Angolan cargoes remaining, traders said Nigerian cargoes are having a harder time finding buyers, particularly as the March export programme for Qua Iboe and Bonny Light are higher than the February levels.

India's MRPL also purchased 1 million barrels of Congolese Coco crude from trader Vitol at a discount of \\$4 a barrel to dated Brent for lifting in the first half of March.
