  •  Well, I believe (meaning my understanding is) (0+ / 0-)

    That there's a difference between Wabasca Heavy Crude and bitumen, despite your assertion otherwise.

    According to crudemonitor.ca, Wabasca heavy crude is:

    What is Wabasca Heavy crude?

    Wabasca Heavy is a blend of heavy oil production obtained by polymer injection and water flooding from the Athabasca region and typically has a 19-20 API gravity and 4.15 wt% sulphur content. Principal producers of the Wabasca Stream include Cenovus Energy and Canadian Natural Resources, though other producers do connect to the Wabasca Heavy stream. Wabasca Heavy is delivered to Edmonton via the Pembina Pipeline and Rainbow Pipelines.

    According to Schlumberger's Oil Field Glossary, bitumen is:

    bitumen
    * * *
    2. n. [Heavy Oil]
    A designation for a hydrocarbon fluid with a gravity of 10° API or lower, based upon the classification of the US Department of Energy.
    Synonyms: ultra heavy oil
    * * *

    So while I am not an expert on oilfield terminology, it is difficult for me to see how two substances:

     - One with an API gravity of 19 to 20

     - The other with an API gravity of 10 or lower

    Are the same thing.

    I'm uncertain about that, which is why I wrote "I believe," because the definitions don't seem to closely align.

    That's what honest people do: acknowledge uncertainty.

    Conversely, people with, well, a bit less honesty tend to blur the distinction between fact and opinion, and state things as simple facts when perhaps reality is a bit more complicated.
