Article by Andrew Nikiforuk describing evidence submitted to the National Energy Board contradicting some lab tests by Enbridge.

I find it very worrying that without independent research "evidence" presented by the resource companies would be taken as fact.

Shouldn't be a surprise since humans are often motivated by self-interest... especially if there are large sums of money involved. All those, ah, "doctors" being paid by the tobacco industry (notwithstanding permanent nicotine stains on their credibility) saying they all prefer Chesterfields.

The Keystone pipeline through the states is looking good to go again, according to bits and pieces in the news, especially since the BC government recently nixed the west coast pipeline (although... more money in the right places might still change that). Looking forward to Idylwyld's beer... Miller High Life.

Hasn't it always been referred to as "heavy oil"?

Some petroleum geologists categorize bitumen from oil sands as extra heavy crude oil due to the density of less than 10 °API (Wikipedia)

Heavy oil refers to viscosity... heavy oil is thick and will not pour easily, while light oil is thin and runny.

A quick google shows that heavy oil's specific gravity can be higher or lower than that of water... applies to freshwater more than seawater which is denser and more likely to float oil. Bitumen is probably variable in density and in order to be pumped through pipelines a thinning agent has to be added which may also cause density to change.

Oilsands leak on northern Alberta weapons range

Canadian Natural Resources Limited reported bitumen emulsion released

Oilsands mixed with water has leaked in northeastern Alberta.

The Alberta Energy Regulator says Canadian Natural Resources Limited reported Monday that bitumen emulsion has been released on the Cold Lake Air Weapons Range.

The regulator put out a news release about it on Thursday.

Regulator spokesman Bob Curran says it's not clear how much has leaked or what caused the release from CNRL's high-pressure cyclic steam project.

Curran says the oilsands mixture has affected a nearby slough.

There were no injuries.

Curran also says it's also unclear if CNRL has stopped the flow of the bitumen emulsion, adding it's believed to be a slow seeping of the product underground that's come to the surface.

He says AER staff were onsite and working with the company.

"The company is responsible for the facility, they're responsible for operating it appropriately and they're responsible for fixing anything that goes wrong with it and our role is to come in and oversee those actions to ensure they're appropriate," Curran said.

He also says it's unknown when the spill actually occurred.

"They are required to notify us as soon as they realize they have a problem, so the moment they discovered it they would be required to report it to us."
