* Force majeure took effect on Friday
* Shell says investigating incident
* Bonny stream was due to export 316,000 bpd in November
(Adds details, trader comments)

LONDON/LAGOS, Nov 19 Royal Dutch Shell Plc's
(RDSa.L) Nigerian venture on Friday declared force majeure on
Bonny Light oil exports after a pipeline was damaged, the latest
disruption to supply in Africa's top exporter.
A Shell spokesman in Nigeria said the force majeure, which
frees the Anglo-Dutch company from contractual deliveries due to
actions beyond its control, took effect from Friday. He gave no
details on any production impact.
"Repair work will commence as soon as the cause is
determined," the spokesman said. "Investigations are ongoing."
The disruption boosted oil prices, oil traders said, because
Nigerian oil is priced in relation to global benchmark Brent
crude [LCOc1>. Brent traded as high as $86.15 a barrel on Friday
before easing by 1517 GMT to $84.33.
Bonny Light is one of Nigeria's larger crude oil streams and
is popular with oil refiners in Europe and the United States.
It was scheduled to export as many as 10 cargoes in
November, equal to about 316,000 barrels per day (bpd) and about
15 percent of Nigeria's expected daily oil exports this month of
2.1 million bpd.
An oil trader who buys Bonny Light said he was waiting for
information about the amount of production affected. "I do
expect some delays to cargoes," the trader said.
There was no immediate evidence of a link to resurgent
militant activity in the oil-producing Niger Delta, where
security forces rescued 19 hostages from a camp on Wednesday.

platform on Nov. 14 had knocked out 45,000 bpd of condensate
