CALGARY, Alberta, Aug 12 (Reuters) - Western Canada Select
heavy blend crude for September delivery widened sharply on
Wednesday after Enbridge Inc ENB.TO shut its Flanagan South
and Spearhead pipelines following a crude oil leak on Tuesday.
WCS traded as low as $21.75 per barrel below the West Texas
Intermediate benchmark, the widest differential in a year,
before paring losses to last trade at $20.25 per barrel below
the benchmark.
On Tuesday it settled at $19.80 per barrel below WTI,
according to Shorcan Energy brokers.
Flanagan South and Spearhead are both major conduits for
Canadian heavy crude to reach the U.S. Gulf Coast.
