How much of the Alberta oil sands has been reclaimed?
Since 1967, of the 940 sq km disturbed by the oilsands industry, industry reports that only 60 sq km (7 per cent) have been permanently reclaimed (See Figure 1). Of this small portion, only one sq km (or 0.1 per cent of overall oilsands mining development) has been reclaimed and returned to the province (See Figure 2).
How are oil sands reclaimed?
The reclamation process includes monitoring, seeding, fertilizing, tree planting, seed collecting, topsoil salvaging and replacing, and landform creation and contouring. One benefit of in situ mining is that it disturbs much less land than surface mining efforts.
Why are the oil sands in Alberta 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. And Canadian oil companies are now bringing their dirty business into the United States.
How much oil is left in Alberta?
Alberta’s oil sands’ proven reserves equal about 165.4 billion barrels (bbl).
Which country reclaimed land from the sea?

Is there land reclamation in Canada?
In Canada, land reclamation efforts are most often directed at land disturbed during natural resource development, including mining and oil and gas operations.
Does the US use Canadian tar sands oil?
America imports some tar sands oil, but expanding U.S. dependence on this polluting fuel is not in our national interest. It’s a bad product, and we don’t need more of it. And energy companies angling for bigger profits shouldn’t play the victim. America remains a trusted trade partner for Canada’s conventional oil.
What are the disadvantages of oil sands?
Cons
- Enormous GHG emissions.
- Relatively low net energy return compared to other sources.
- Large amounts of water required: roughly 3:1.
- Water pollution.
- Destructive to major boreal forest.
- Widespread habitat destruction, both on land and water.
- Requires expensive and risky pipelines.
How much money do the Alberta oil sands make?
Direct federal personal income taxes from persons Federal personal income taxes paid by tax filers employed in the oil and gas extraction sector in Alberta has ranged from $2.2 billion to $3.4 billion between 2007 and 2018, or an annual average of $2.7 billion per year over the period.
Can oil sands mining be reclaimed?
Other oil sands mining companies have their own projects as well. Reclaiming the oil sands surface mines is not a matter of a project here and another one there.
What is reclamation in the oil sands?
Oil sands development is subject to some of the strictest environmental regulatory standards in the world which requires 100% reclamation after operations cease, meaning that the land used by industry is returned to a “self-sustaining ecosystem with local vegetation and wildlife.”
What is the active footprint of Alberta’s oil sands?
According to the latest data from the Alberta government (2016), the active footprint of various stages of oilsands reclamation and disturbance was: Soils placed (terrestrial & wetlands & aquatics) – 1,450.2 hectares Permanent reclamation (wetlands & aquatics) – 1,275.5 hectares
What happens to the land after oil sands are extracted?
The Government of Alberta requires that companies remediate and reclaim 100 percent of the land after the oil sands have been extracted. Reclamation means that land is returned to a self-sustaining ecosystem with local vegetation and wildlife.
