What is tar sands quizlet?
What are tar sands? (oil sands) are a combination of clay, sand, water, and bitumen, a heavy black viscous oil. Tar sands can be mined and processed to extract the oil-rich bitumen, which is then refined into oil.
What are tar sands?
Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen. Bitumen is made of hydrocarbons—the same molecules in liquid oil—and is used to produce gasoline and other petroleum products.
How is oil extracted from Canadian tar sands quizlet?
Canada has the world’s largest bitumen reservoir, but much of it is trapped in tar sands. They trap heavy, black oil called bitumen. Tar sands can be mined and processed to produce a substitute for petroleum. Tar sands mining is more efficient than harvesting conventional sources of oil.
What are oil sands apes?

Where are tar sands found?
The largest tar sand deposits are found in Canada (primarily in Alberta), Venezuela and several countries in the Middle East. The majority of U.S. tar sands resources are located in eastern Utah, with an estimated 12 billion-19 billion barrels of reserves.
How is Canadian tar sand oil extracted?
Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant.
Are tar sands bad?
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 much of the oil is left in the ground after secondary recovery What happens to this oil?
After secondary recovery, typically only around 30% of the oil in the reservoir has been recovered and around 70% remains in the ground, and so an operator can consider tertiary recovery (known as EOR). EOR can reverse the decline of mature fields and increase the overall percentage recovered.
Why is tar sands oil 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. In fact, it has become one of the fastest-growing sources of greenhouse gas emissions in that country.
