Where do tar sands come from?

The largest deposits of tar sands in the world are found in Alberta (Canada) and Venezuela. The largest deposits in the United States are found in eastern Utah. Tar sands represent a potentially vast reserve of oil but come with their own environmental challenges.

How is tar sands formed?

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. Over millions of years, that oil became trapped in thick layers of sand.

Where is tar sands produced?

The largest deposits of tar sands in the world are found in Canada, and Venezuela, and much of the rest is found in various countries in the Middle East. In the United States, tar sands resources are primarily concentrated in eastern Utah, mostly on public lands.

Which country produces the most tar sands?

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.

What are tar sands made of?

The oil sands (or tar sands as they are sometimes inaccurately referred to), are a mixture of sand, water, clay and a type of oil called bitumen.

Canada's Tar Sands: The most destructive project on Earth? - Truthloader

Does the U.S. refine tar sands?

The US Has the Most Capacity to Refine Bitumen in the World

In the US, 59 of the 134 refineries are equipped with coker units. Approximately 30% of the US's bitumen refining capacity is in the nine Gulf of Mexico refineries TransCanada seeks to supply through its controversial Keystone XL pipeline.

Does the United States use tar sand?

America imports some tar sands oil, but expanding U.S. dependence on this polluting fuel is not in our national interest.

Is Alberta oil the cleanest in the world?

We're entering a golden age for oilsands production. The massive industrial-scale nature of oilsands production worked for decades to make producing oil in the Fort McMurray region a higher-cost and higher-emissions proposition.

Why is tar sand the world's dirtiest oil?

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.

Does Russia have tar sand oil?

Four major deposits of tar sands in the Russian Federation, with the largest called Tunguska remotely tucked away in Siberia. The three other deposits are in the Caucasus with the most well known of them being the Volga-Urals.

How are tar sands mined and processed?

Open Pit Mining

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.

Where does the oil from the Keystone pipeline go?

Operating since 2010, the original Keystone Pipeline System is a 3,461-kilometre (2,151 mi) pipeline delivering Canadian crude oil to U.S. Midwest markets and Cushing, Oklahoma.

Is tar sands a fossil fuel?

tar sand, also called bituminous sand, deposit of loose sand or partially consolidated sandstone that is saturated with highly viscous bitumen. Oil recovered from tar sands is commonly referred to as synthetic crude and is a potentially significant form of fossil fuel.

How much tar sands are left?

About 15% of this is currently recoverable, which amounts to about 75% of the petroleum reserves in North America. Only recently (with dramatic changes in the way the world views oil reserves) these oil sands have come to be included in the tally of global petroleum reserves.

How much oil is in Canada's tar sands?

Reserves and production

Alberta's oil sands has the fourth-largest oil reserves in the world, after Venezuela, Saudi Arabia and Iran. Alberta's oil sands' proven reserves equal about 165.4 billion barrels (bbl). Crude bitumen production (mined and in situ) totaled about 2.8 million barrels per day (bbl/d) in 2017.

Why doesn't Canada produce more oil?

Because of limited pipeline capacity and export infrastructure, Canada sells 99% of its oil into a saturated North American market at low prices. This means Canada isn't getting full value for its resources.

How long will Canada's oil reserves last?

Oil Reserves in Canada

Canada has proven reserves equivalent to 188.3 times its annual consumption. This means that, without Net Exports, there would be about 188 years of oil left (at current consumption levels and excluding unproven reserves).

Does Alberta still produce oil?

The limits were intended as a short-term measure, but ongoing delays to pipeline projects led to the curtailment policy being extended through December 2021, but no monthly oil production limits have been in effect since December 2020.

What is the dirtiest oil?

Tar sands are the dirtiest source of oil on Earth. This extreme source of oil is currently being mined mainly in Alberta Canada, however, oil companies are now pursuing tar sands mines in the U.S. West. Tar sands are composed of clay, sand, water, and bitumen (a heavy black hydrocarbon).

Who buys oil from Canada?

The majority of the crude oil exported from Canada goes to the United States. In 2020, the U.S. received 179.7 million metric tons of oil from Canada, while Europe received 4.7 million metric tons.

Can Canadians refine oil?

Canada is home to 18 refineries: 5 in Alberta, 5 in Ontario, 2 in British Columbia, 2 in Saskatchewan, 2 in Quebec, 1 in New Brunswick, and 1 in Newfoundland and Labrador. Together they have a total refining capacity of nearly 2 million barrels of oil a day.

Does Canada use the tar sands oil?

Canada's oil and gas sector is the largest and fastest rising source of greenhouse gas emissions in Canada, accounting for 26% of the total. The tar sands are a key culprit. Between 1990 and 2018, tar sands production increased by 456%. The industry's carbon footprint is greater than New Zealand and Kenya combined.

Is Canadian tar sand oil used for gasoline?

The largest deposits of tar sands are found in Alberta, Canada. While tar sands have been in production since the late 1960s, and currently account for about 5 percent of all U.S. gasoline, production has been scaling up—which could have serious consequences for the air, water, and climate.

Can tar sands be made into gasoline?

It is sometimes labeled as an extra-heavy crude oil but is essentially bitumen or tar. Refineries convert crude oil into light hydrocarbons such as gasoline and diesel. As bitumen is so heavy, converting it into these light hydrocarbons requires several intensive processes.
