March 5 (Bloomberg) -- Western Canada Select crude sank after Enbridge Inc. shut a pipeline that transports oil from Superior, Wisconsin, to Illinois-area refineries.
Supplies of heavy oil may increase after Syncrude Canada Ltd. shut a coker with about 100,000 barrels a day of capacity following a March 2 fire. The unit remains shut while being assessed, Siren Fisekci, a spokeswoman in Calgary for Canadian Oil Sands Ltd., the project’s largest shareholder, said today in a telephone interview.
Western Canada Select’s discount to U.S. benchmark West Texas Intermediate weakened $1 to $33 a barrel at 2:05 p.m. in New York, the widest gap since Feb. 29, according to data compiled by Bloomberg.
Syncrude oil slipped 80 cents to $5.80 a barrel below WTI. The discount for Bakken oil weakened $2 to $17 a barrel.
Enbridge was forced to halt crude deliveries on lines 14 and 64 after two vehicles collided March 3, starting a fire at a pumping station near New Lenox, Illinois, 36 miles (58 kilometers) southwest of Chicago.
The Calgary-based company may start operating Line 14 on March 7 and Line 64 the following day, Lorraine Little, a spokeswoman in Superior, Wisconsin, said in an e-mail yesterday. Lines “upstream of Superior will require slowdown or shutdown to manage tank levels,” she said.
