The plumbing behind the numbers. Ten plain-language explainers on how the oil sands actually works: the plants, the pipes, the ownership, and the commercial logic. No forecasts, no model output, just the institutional knowledge that makes the numbers legible. Written for a new hire on a WCSB desk.

Ten entries · written September 23, 2026.

  1. 1. The Scotford chain
    Muskeg River and Jackpine mines, the Corridor pipeline, and a Shell-operated upgrader outside Edmonton. How CNRL's mined bitumen becomes synthetic crude.
  2. 2. The Sturgeon refinery
    The government-backed bitumen refinery northeast of Edmonton. Fifty thousand barrels a day of bitumen that never sees an export pipe.
  3. 3. The upgrader interconnects
    The bitumen lines between Suncor and Syncrude, and the outage playbook they make possible.
  4. 4. NFT vs PFT bitumen
    Why some mined bitumen has to go through an upgrader, and some can go straight to a pipeline.
  5. 5. Diluent 101
    The light oil that makes bitumen move, and the 30 percent of every dilbit barrel you are really buying.
  6. 6. Mine capacity vs upgrader capacity
    Two plants, two numbers. Never blend them.
  7. 7. The synthetic grades
    SYN, Premium Albian, and the other light barrels of the oil sands.
  8. 8. SAGD vs CSS vs mining
    The three ways to get bitumen out of the ground.
  9. 9. How turnarounds move barrels
    Planned shutdowns, the Horizon September 2026 example, and why the calendar beats the snapshot.
  10. 10. Egress 101
    The pipes out of Alberta, apportionment, and why full pipes set the price.
