Oil prices edge up more after Brexit shock

Crude oil rose more on Wednesday as traders moved money back into markets hit by the initial shock of Britain's vote to leave the European Union, while a potential oil workers strike in Norway and a crisis in Venezuela's oil sector also provided support.

Brent crude futures were 31 cents higher at $48.89 per barrel at 1219 GMT. US crude was up 40 cents to $48.25 a barrel.
