By Konstantin Rozhnov Of DOW JONES NEWSWIRES LONDON (Dow Jones)--Crude-oil futures rose Friday in volatile trade, with trading volumes thinner than usual amid uncertainty over the outlook for Europe's sovereign debt crisis. Market participants are also awaiting the U.S. employment report for October, due 1230 GMT, as it "will be able to offer a better picture of the overall economy and the investor's reaction could easily spill over into the energy sector," London Capital Group said in a note. At 0950 GMT, the front-month December Brent contract on London's ICE futures exchange was $1.14, or 1%, higher at $111.97 a barrel. The front-month December contract on the New York Mercantile Exchange was trading up 66 cents, or 0.7%, at $94.73 a barrel. Oil prices are expected to remain volatile throughout the day, said Christophe Barret, global oil analyst at Credit Agricole. -By Konstantin Rozhnov, Dow Jones Newswires; +44 207 842 9956; konstantin.rozhnov@dowjones.com
