I've had a look at some of the gravities on post upgrader oil and have wondered how it moves through a pipe.
Didn't some light cuts get routed back to Alberta as cutter stock ?

You have seen more than I then. I have read the descriptions of what the upgrader is supposed to accomplish. I wonder if they blend in bitumen to the limit of the ability to flow.

It may be the difference between a minimal upgrading and full upgrading, done differently by different companies.

I believe that is true.
