RUDE CRUDE

Crude-oil futures ripped higher early Friday as energy traders weighed a report of an explosion in Saudi Arabia, escalating tensions in Iraq and a report of more trouble for Royal Dutch Shell in Nigeria against U.S. data showing the nation well supplied with oil and petroleum products.
Crude for April delivery jumped as much as $62.38 a barrel, up $1.84, after a report sourcing the al-Arabiya television channel of an explosion and shots fired at an Eastern Saudi Arabian oil refinery.
