CALGARY, Alberta, Oct 17 (Reuters) - Canadian cash crude prices strengthened on Thursday after TransCanada Corp warned of a possible natural gas pipeline rupture on the Nova system in Northern Alberta.
Western Canada Select heavy blend for November delivery was last trading at $27.50 per barrel below the West Texas Intermediate benchmark, according to Shorcan Energy brokers.
That compares with a settlement price of $30.00 per barrel below the benchmark on Wednesday.
Light synthetic crude from the oil sands for November delivery strengthened to $9.50 per barrel below WTI, compared with Wednesday’s settlement price $10.60 under the benchmark.
Traders in Calgary said news of the possible rupture was affecting oil prices because crude producing plants need gas to operate.
