WAfrica Crude-Nigerian weaker, IOC tender out

* Qua Iboe offered at dated plus $1.00, down 10 cents

* IOC buys 1 mln barrels Escravos & Erha via tender

* Shell buys Bonga around dated plus 90 cents

* ENI sells end-Aug Nemba to U.S. buyer

LONDON, July 3 (Reuters) - Poor gasoline refining margins
and weaker demand for crude in floating storage due to a
narrowing of contango kept Nigerian differentials under pressure
on Friday.

"Demand from the United States isn't there and floating
storage doesn't seem to be an option anymore so Nigerian is
really going down now," one physical crude trader said.

NIGERIA

* Gunvor sold its Aug. 15-16 Bonga cargo to Shell at around
dated BFOE plus 90 cents, traders said.

* Nigeria's benchmark Qua Iboe BFO-QUA was offered by
Exxon at dated plus $1.00 on Friday, below the last deal done at
dated plus $1.15.

* Six Bonny Light cargoes are expected to load in August --
three new cargoes and three delayed from July -- and values are
said to be around dated BFOE plus 80 cents.

* Brass River was assessed around dated BFOE plus 80 cents
or a little lower.

ANGOLAN GRADES

* ENI sold a Aug. 31-Sep. 1 loading Nemba cargo to
ConocoPhilips, traders said. No price details were available and
the grade was assessed at around dated plus 30 cents.

ASIAN TENDERS

* Indian Oil Corp (IOC) bought via tenders 1.0 million
barrels each of Nigerian Erha and Escravos grades for September
loading from European trader Trafigura, trade sources said.

Erha was assessed at dated plus $1.00-1.10 on Friday, while
Escravos was pegged at dated plus 60 cents.

* India's Bharat Petroleum Corp issued a tender on Thursday
to import up to 3 million barrels of crude for deliveries in
August-September. The refiner is seeking up to 2 million barrels
of sweet crude for August-September deliveries and 1 million
