Oil surges

Oil prices rose on Wednesday as ongoing cuts of piped Canadian crude to the United States added to falling U.S. crude inventories, while expectations of a prolonged OPEC-led production cut also offered support.
U.S. West Texas Intermediate (WTI) crude futures were at $57.68 a barrel at 0454 GMT, up 85 cents, or 1.5 percent from their last settlement.
Brent crude futures, the international benchmark for oil prices, were at $62.97 per barrel, up 40 cents, or 0.6 percent.
Traders said the firm price lift was due to drop in crude supplies from Canada to the United States.
TransCanada Corp said it will cut deliveries by at least 85 percent on its 590,000-barrel-per-day (bpd) Keystone crude pipeline through to the end of November.
The pipeline, which links Alberta´s oil sands to U.S. refineries, was shut last week after a 5,000-barrel spill in South Dakota.
