The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market. [27]

According to the U.S. Geological Survey, bitumen is further distinguished as extra-heavy oil with a higher viscosity (i.e., resistance to flow): "Natural bitumen, also called tar sands or oil sands, shares the attributes of heavy oil but is yet more dense and viscous. Natural bitumen is oil having a viscosity greater than 10,000 cP."
The Tar Sand Triangle is located in Southeastern Utah and covers an area of 148,000 acres (600 km 2). It is located between the Dirty Devil and Colorado Rivers in Wayne and Garfield Counties. The Tar Sand Triangle is the largest deposit of oil sands in the United States known today.
Much of Canada's petroleum effort has focused on producing oil from the oil sands (sometimes called "tar sands") of northern Alberta.To appreciate these resources, it is important to understand a simple concept from chemistry and physics: the "gravity" of crude oil and natural gas liquids.
The world's largest deposit of natural bitumen, known as the Athabasca oil sands, is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. [24] Isotopic studies show the oil deposits to be about 110 million years old.

(The data below does not seem to include shale oil and other unconventional sources of oil such as tar sands. For instance, North America has over 3 trillion barrels of shale oil reserves, [ citation needed ] and the majority of oil produced in the US is from shale, leading to the paradoxical data below that the US will finish all its oil at ...
Mixing tar with linseed oil varnish produces tar paint. Tar paint has a translucent brownish hue and can be used to saturate and tone wood and protect it from weather. Tar paint can also be toned with various pigments, producing translucent colors and preserving the wood texture. Tar was once used for public humiliation, known as tarring and ...
