* On the Angolan market, state oil firm Sonangol was offering two cargoes of Dalia.

* Around 10 cargoes of February-loading Angolan crude were still believed to be available for sale.

* At least 20 Nigerian cargoes were still available but with tenders this week from IOC and Turkey's Tupras, the market remained reasonably well supported, one trader said.

* IOC has issued a tender to buy crude oil loading March 1-10 that closes on Thursday.

* South Africa's Sasol awarded a tender to Chevron and took Nigerian Pennington grade.

* Bonny Light and Qua Iboe were heard to be offered at a premium to dated Brent of around $1.80, well above levels indicated two weeks ago, when both grades were closer to $1.60-1.65.
