MYTH: Oil sands crude is more corrosive than conventional crude oil.
This myth, invented by oil sands opposition groups without any evidence has been debunked by some of the world’s leading and most respected scientific research organizations including the National Academy of Sciences, Natural Resources Canada, Battelle Memorial, Penspen Institute and Alberta Innovates at the University of Calgary.
Each one of these studies found:
- No evidence of causes of pipeline failure unique to the transportation of diluted bitumen
- No evidence of chemical or physical properties of diluted bitumen that are outside the range of other crude oils
- No evidence that any aspects of the transportation of diluted bitumen by transmission pipeline would cause releases more likely than the transportation of other crude oils
- The dilution process needed to help these heavy oils flow yield a stable and fully mixed product for shipping by pipeline with density and viscosity levels in the range of other crude oils transported by pipeline in the United States
- No evidence of unique or extreme properties that make diluted bitumen shipments more likely to cause internal corrosion or erosion
The fact is oil sands crude is very well understood by scientists and engineers and has been shipped safely through pipelines for nearly 50 years. Every batch of crude oil entering TransCanada’s Keystone Pipeline is tested to ensure it meets strict specifications before being transported to the United States.
