Producers in the Western Canadian Sedimentary Basin (WCSB) are in a bind. Crude oil output in the WCSB has risen by more than 50% over the past seven years to about 4 MMb/d and is expected to increase to 5 MMb/d by the mid-2020s. But there has been only a modest expansion of refinery capacity within the region and pipeline capacity out of the WCSB, and lately takeaway constraints have had a devastating effect on the price relationship between benchmark Western Canadian Select (WCS) and West Texas Intermediate (WTI). What’s ahead for WCSB producers and WCS prices? Today, we continue our series on Western Canadian crude and bitumen markets, this time focusing on WCSB refinery capacity and existing pipelines out of the region.
