What would it cost to build the pipeline and maintain it?

What would it cost to build a refinery in Alberta and do the refining there?

[thackney]

If you built the refinery(s) in Alberta for this oil, then you would need to build a pipeline to deliver the gasoline, diesel, jet fuel, etc.

Refineries also produce other products besides transportation fuel. Our local refineries have other pipelines then to deliver products like propane & ethane to chemical plants.

They also produce residual oil or petroleum coke. We have existing transportation systems and/or local markets to handle those as well.

Or you could just extend one pipeline to send the crude oil/bitumen to existing refineries and spend a lot less money while using the existing systems and replacing imported oil from overseas.

Order of magnitude estimates: 700 kb/d pipeline, $7BB, 700 kb/d refinery, $15B plus the cost of products pipelines to move gasoline and diesel fuel to markets, about another $5B.
