* Nigerian exports to fall 70,000 bpd in Feb
* India's IOC seeks March arrival cargoes in tender
LONDON, Jan 4 (Reuters) - Nigeria's oil exports are set to decline in February to an eight-month low because of reduced supplies from several crude streams in a short month, trade sources said on Tuesday.
Many buyers covered their immediate requirements before the Christmas break, which left many Angolan and Nigerian cargoes for February already traded.
Reduced supply has been supporting differentials for Nigerian crude, although narrower refining margins could weigh on sentiment, traders said.
NIGERIA
* Qua Iboe: Valued at dated plus $2.00 to plus $2.10 on Tuesday, unchanged. The last concrete offer heard for Qua was dated plus $2.20.
ANGOLA
* Little is left for loading in February with many crude streams already sold out.
ASIAN BUYING TENDERS
* India's largest state-owned refiner Indian Oil Corp (IOC) has issued a tender to buy March arrival sweet crude, a trader said on Tuesday.
The tender will close on Jan. 4 with bids valid until a day later, he said.
