Heavy Canadian Crude Weakens After Enbridge Shuts Oil Pipe 6A

Western Canada Select oil’s discount widened versus U.S. benchmark West Texas Intermediate after Enbridge Inc. shut its 608,800-barrel-a-day 6A crude pipeline early today.

There are no operational problems and the line was expected to return to service later today, Graham White, a Calgary-based company spokesman, said in an e-mail. The company doesn’t expect any impact on deliveries, he said.

“Lines are shut down and reactivated throughout the month for various reasons,” Graham said.

Line 6A transports crude between Superior, Wisconsin, and Griffith, Indiana, according to the company’s website.

Western Canada Select’s discount widened $1 to $25 a barrel at 2:06 p.m. in New York, according to data compiled by Bloomberg. Syncrude’s discount to WTI narrowed 25 cents a barrel to $6.75. Bakken oil’s discount was steady at $11.65.

U.S. Gulf Coast crude grades strengthened. Light Louisiana Sweet’s premium to WTI gained 95 cents to $13.55 a barrel. Heavy Louisiana Sweet’s premium increased $1.30 to $16.45 a barrel.

Mars Blend’s premium gained 85 cents to $11.70. Southern Green Canyon’s premium widened $1.10 to $12. Poseidon’s premium increased $1 to $12.25.

The premium for Thunder Horse, a sour crude with lower sulfur content than Mars, Poseidon and Southern Green Canyon, widened $1.30 to $13.55 a barrel.
