LONDON: Nigerian crude differentials were steady on Friday close to multi-year lows, pressured by a large quantity of unsold cargoes for loading in early 2015 and ample global supply.

The premium for Qua Iboe, Nigeria's biggest crude stream, was assessed at dated Brent plus 35 cents on Dec. 30, the lowest since 2005 according to Reuters data, and at dated plus 40 cents on Friday.

Trade was thin as many market participants are not returning to their desks until next week.
