Pros
- Very large supply. Second largest oil field in the world.
- Economically recoverable.
- Less than 5 percent has been produced.
- GHG emissions could potentially be minimized through CCS.
What is the difference between oil and oil sands?
Oil is a natural occurring combination of sands, bitumen, water, and clay or other minerals. It is a very viscous and heavy type of oil. Oil sands is a naturally occurring petrochemical that can be upgraded into crude oil and other petroleum products.
Are oil sands good or 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 does tar sands oil differ from traditional crude oil?
Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon. Like the kerogen in oil shale, tar sands’ bitumen can be upgraded to synthetic crude oil. As with oil shale, once released, the bitumen from tar sands must be upgraded and refined further before it’s usable as a fuel source.
What is wrong with the oil sands?
Burning tar sands oil creates more pollution than regular crude. Tar sands generate 17 percent more carbon emissions than conventional oil. Ramping up dirty tar sands oil production means a giant step back in the fight against climate change, and that’s the last thing we need.
Are oil sands expensive?
High cost and low value Oil sands are among the world’s most expensive hydrocarbon resources, and the heavy, sulfur-rich crude fetches a lower price than the “light sweet” crude that sets the benchmark for the value of oil.
Are oil sands natural?
Oil sand is a naturally occurring mixture of sand, clay or other minerals, water, and bitumen. Bitumen can be extracted using two methods, depending on how deep the deposits are below the surface. Find out more about various oil sands extraction processes.
How many years oil is left in the world?
World Oil Reserves The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).
Who owns the oil sands?

Why is Canadian crude oil so cheap?
Canadian heavy crude has become so cheap that the cost of shipping it to refineries exceeds the value of the oil itself, a situation that may result in even more oil-sands producers shutting operations. Synthetic crude, produced from oil-sands bitumen that’s been run through an upgrader, fell to $9.56 a barrel.
How dirty are oil sands?
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. Refining the sticky black substance produces piles of petroleum coke, a hazardous by-product.
Is oil still being formed?
If oil is constantly being formed by the heat and pressure of the earth’s mantle, is there enough oil to last us forever? The short answer is no. We’re quickly using up all the accessible oil in the planet’s crust, and it will take millions of years for more to form.
Who owns most of the oil?
Russia is the largest country in the world by landmass and over 106 billion barrels of proven oil reserves fall within the country’s borders. Along with the U.S. and Saudi Arabia, Russia is one of only three countries in the world producing more than 10 million barrels of oil per day.
Why are oil sands bad for the environment?
Climate Impacts: The greenhouse gas emissions for oil sand extraction and processing are significantly larger than for conventional crude oil. These emissions contribute to global warming and the enhanced greenhouse effect.
