LONDON, Feb 8 (Reuters) - Nigerian differentials fell on Friday for a second day due to a power failure at the Qua Iboe export facility earlier in the week, two traders said, sending prices to their lowest level in three weeks.
* Qua Iboe BFO-QUA for March loading was offered at a premium of between $1.80 and $1.90 a barrel above dated Brent, down from around $1.95 the previous day and from around $2.15 at the start of this week, the traders said
* The power outage prompted operators to load crude onto supertankers at around 25,000 barrels an hour, slower than normal rates around 30,000 barrels an hour
* An overhang of unsold cargoes also helped bring down prices of Bonny Light and Qua Iboe, which had been indicated at more than $2 a barrel above dated Brent throughout February
* Vitol sold a cargo of Qua Iboe, though the identity of the buyer was not immediately clear
* Spanish oil major Cepsa was heard to have bought a cargo of Usan from Chevron, according to one trader, but that could not be immediately confirmed
* Demand for Angolan crude from Chinese refiners in the run-up to the Lunar New Year holiday all but drained supplies of March-loading cargoes
* Benchmark oil prices edged up on Friday but were heading for a weekly loss, pulled down by worries about a global economic slowdown
* Libya’s National Oil Corp said on Friday that its largest oilfield, out of action since December, would remain offline until security had been restored — a day after forces loyal to an Eastern Libya commander seized parts of the facility
* U.S. House of Representatives committee passed a bill on Thursday that would open up the Organization of the Petroleum Exporting Countries (OPEC) crude oil producer group to antitrust lawsuits.
