Imperial Oil Ltd said it had shut all production at its 220,000-barrel-per-day (bpd) Kearl oil sands site in Canada due to an outage of part of the Polaris diluent pipeline following the spill.
Western Canada Select (WCS) heavy blend crude for October delivery in Hardisty, Alberta, traded at $9.40 per barrel below WTI, according to NE2 Canada Inc. It settled the previous day at $9.90 under.
The pipeline outage crimped supplies as Canadian oil sands companies were steadily restoring production that had been shut in after the coronavirus pandemic spread and curbed demand from refineries.
Light synthetic oil from the oil sands for October delivery traded at $2.75 below WTI, unchanged from the previous day’s settle.
