This document is a final report for a series of physical and chemical tests that were conducted on the fate and behaviour of diluted bitumen oils at a test facility in Gainford, Alberta. Additionally, as part of this study, a series of tests were conducted to determine the efficiency of various types of oil spill response equipment under similar conditions.
Diluted bitumen (dilbit) crude oil represents a range of oils produced from bitumen extracted from oil sands in Western, Canada. As these reserves are increasingly in demand, more transportation options are being sought to deliver the product to refineries both in North America and abroad. Concerns over potential spills have been the point of discussion with questions raised about applicable countermeasures and limitations, the possible fate and behaviour of these oils, and environmental effects.
Properties, Composition and Marine Spill Behaviour, Fate and Transport of Two Diluted Bitumen Products from the Canadian Oil Sands
This study reports the early research simulating diluted bitumen products spilled at sea. This work was undertaken by the Government of Canada as part of the first phase of a strategy to implement a world class prevention, preparedness and response regime for oil spills from ships.
A new report from the National Research Council, finds that diluted bitumen has no greater likelihood of accidental pipeline release than other crude oils. The committee that wrote the report found that diluted bitumen has physical and chemical properties within the range of other crude oils and that no aspect of its transportation by pipeline would make it more likely than other crude oils to cause an accidental release.
The Canadian Energy Pipeline Association (CEPA) identified a need for a State of the Art Report on Dilbit corrosivity compared to conventional crude oils within oil transmission pipelines. This report has been prepared by Consultants from outside North America.
The Natural Resources Canada has published a news release that states both scientific research and industrial experience have determined that bitumen-derived crude oil is no more corrosive in transmission pipelines than other crudes.

This report provides an independent expert assessment of the crude quality aspects, including supplementary information related to dilbit homogeneity, crude volatility and crude petroleum acidity.
Alberta Innovates – Technology Futures reviews the current status on the corrosivity of dilbit in pipelines as compared to conventional or ‘non-oil sands derived’ crude oil.
