The Alberta oil sands development
- 3 things to know
- Component 2
Overview
The Alberta oil sands as a case study of energy resource development, covering how bitumen is extracted, the effects on land, water, wildlife and nearby communities, the greenhouse gas emissions, and the pipelines that carry the oil to market.
What you need to know
Answer each one before you reveal it.
How does in situ oil sands extraction affect wildlife in Alberta?
What happened to ducks at Syncrude's Aurora tailings pond in 2008?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What are the Alberta oil sands?
Model answer
Deposits of sand saturated with heavy bitumen in northern Alberta, Canada, mainly around Fort McMurray and the Athabasca River, which give Canada some of the world's largest proven oil reserves.
- 2
How is bitumen extracted from the Alberta oil sands?
Model answer
Shallow deposits are strip-mined and the bitumen washed out with hot water, while deeper deposits are extracted in situ by injecting steam to make the bitumen flow to wells.
- 3
How has oil sands development affected land in Alberta?
Model answer
Around 900 km² of boreal forest, peatland and wetland has been disturbed by mines, well pads and infrastructure, and only a very small area has been certified as reclaimed.
- 4
What are tailings ponds in the Alberta oil sands?
Model answer
Lakes of toxic waste water, sand, clay and residual bitumen left after processing, which now hold over 1.4 trillion litres and cover more than 300 km².
- 5
What happened to ducks at Syncrude's Aurora tailings pond in 2008?
Model answer
About 1,600 ducks died after landing on the pond, and Syncrude was found guilty and paid a penalty of about C$3 million.
- 6
How does oil sands development affect the Athabasca River?
Model answer
Large volumes of water are withdrawn for processing, and seepage from tailings ponds raises concerns about contamination downstream.
