W.Africa Crude-Differentials little changed as traders assess market

West African crude oil differentials were little changed Monday as traders continued to assess higher freight costs and demand.

* The market has been on the quieter side owing to a recent rise in freight costs, a trade source said.

* Among offers on Monday were Angola's Girassol at dated Brent plus $1.50 and Hungo at dated Brent plus 59 cents.

* Nigeria's Brass River grade was offered at dated Brent plus $3.

* September cargoes have largely been sold, with fewer than 10 left, the source said.

* There are about 50 unsold cargoes for October with more than half from Nigeria.
