Access Western Blend

Stream Description

Access Western Blend (AWB) is a heavy, high TAN dilbit produced by Canadian Natural Resources and MEG Energy. Production is from the Athabasca region south of Fort McMurray, Alberta. Production is generated by SAGD thermal methods. Diluent is supplied to the production sites from Edmonton and dilbit is pumped back to Edmonton on the Access Pipeline. AWB is available for upgrading in the Edmonton area, and for export on the Enbridge and Trans Mountain systems.

Batch: AWB-6165 --- Date: October 02, 2025 --- Sample Location: Edmonton

Access Western Blend saw marginally increased density, sulphur, MCR, and metals, along with reduced BTEX and C7 x C10 contents, for the October sample. Simulated distillation results showed smaller naphtha and distillate cuts with a larger residue.
