How do the Alberta oil sands affect water quality?
Industrial processes, such as tar sands mining, create toxic tailings lakes that are poisoning Canadian rivers, lakes and streams and the life that depends on those water bodies. This method of bitumen extraction requires enormous quantities of water — much of which is being drawn from Alberta’s Athabasca River.
Why do they heat up the oil sands to separate out the oil in Alberta?
That’s because the low-grade crude oil, called bitumen, is thick and viscous. It has a tar-like consistency and is almost solid at room temperature, which means it can’t be extracted from the ground using traditional drilling techniques.
Why the Alberta oil sands project is harmful to the environment?
Tar sands extraction emits up to three times more global warming pollution than does producing the same quantity of conventional crude. It also depletes and pollutes freshwater resources and creates giant ponds of toxic waste.
How do oil sands affect water?
Oil sands development consumes large amounts of water and energy—currently, two to five barrels of water (natural sources and recycled water) are required for every barrel of oil produced by mining—and produces byproducts such as contaminated tailings.
How much water is used in Alberta oil sands?
Water-Use Intensity In 2020, oil sands mining used 279 million m3 of nonsaline water (32 per cent of all nonsaline water allocated for oil sands mining) to produce 604 million BOE.
When was the Keystone pipeline supposed to be finished?
A press release from TransCanada in 2008 estimated the Keystone XL costs at approximately US$7 billion with a completion date of 2012. From January 2018 through December 31, 2019, Keystone XL development costs were $1.5 billion.
How is oil extracted in Alberta?
The deposit is mined and trucked to a main processing plant. Hot water is added to the oil sands, producing a pumpable slurry. Bitumen is recovered through a gravity separation process. About 20% of Alberta’s bitumen reserves are close enough to the surface to be mined.
How were the oil sands formed in Alberta?
Alberta’s oil sands were formed millions of years ago, as tiny marine creatures died and drifted to the sea floor and were covered by layers of sediment that exerted enough pressure and temperatures to transform the organic matter into oil.
What are the bad things about oil sands?
Tar sands oil — even the name sounds bad. And it is bad. In fact, oil from tar sands is one of the most destructive, carbon-intensive and toxic fuels on the planet. Producing it releases three times as much greenhouse gas pollution as conventional crude oil does.
How dirty is Canadian oil?
And yet, Canada’s oil is one of the dirtiest in the world. A study published in the prestigious journal Science found that 46 countries produced oil with a lower per barrel carbon footprint than Canada. Only three countries were worse: Algeria, Venezuela, and Cameroon. We’re 47th out of 50 countries.
What is Alberta oil called?
bitumen
When we talk about Alberta’s crude oil — specifically, bitumen from the oilsands — we look at a benchmark price called Western Canadian Select (WCS).
What is Alberta oil used for?
Most of the crude oil produced in Alberta, is exported to other markets. The crude oil that remains in the province is refined into transportation fuels and other oil products to heat homes and buildings, generate electricity, and manufacture lubricants, waxes, plastics, synthetic rubber and asphalt.
How does Alberta oil sands affect climate change?
All told, producing and processing tar sands oil results in roughly 14 percent more greenhouse gas emissions than the average oil used in the U.S. And greenhouse gas emissions per barrel have stopped improving and started increasing slightly, thanks to increasing development of greenhouse gas–intensive melting-in-place …
