Western Canadian Blend

Stream Description

WCB (Western Canadian Blend) is an aggregate of heavy sour crude production (21 API gravity, 3.0 wt% sulphur) in the Wainright and Hardisty regions. Unique to WCB is an agreement by the gathering systems to not use field butanes as diluent. Though there are many connections to WCB, the principal contacts would include Cenovus Energy and Repsol.

Most Recent Sample Details

Batch: WCB-1117 --- Date: March 07, 2025 --- Sample Location: Hardisty

Slightly increased butanes and pentanes were observed for the March sample of Western Canadian Blend. Simulated distillation results showed a larger naphtha and smaller residue compared to typical.
