West Texas Sour’s discount to West Texas Intermediate widened after Enbridge Inc. said it will apportion space by an additional 26 percent on its crude-oil pipelines 6A, 14 and 62 for December deliveries.
Enbridge is making the move because of high nominations from shippers and temporary capacity restrictions in Line 6A, Jennifer Varey, a company spokeswoman, said in an e-mail. Apportionments are made when nominations exceed capacity.
The plentiful supply of oil could weigh on sour crude grades as overall system inventories for Enbridge rose 1.26 million barrels to 16.1 million on Nov. 30 from 14.9 million on Nov. 25, the day of an electrical failure at the company’s Lockport, Illinois, terminal.
