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. [3]
The Athabasca Sand Dunes are estimated to be approximately 8,000 years old, formed near the end of the last glacial period. [2] As glaciers receded, meltwater washed enormous quantities of sand, silt and sediment from local sandstone into Lake Athabasca, whose water level was at the time much higher than currently.
[5] [17] The highest-grade uranium deposits in the world are found at the unconformity between these clastic layers and the Precambrian bedrock. [18] The Athabasca Sand Hills protected by The Athabasca Sand Dunes Provincial Park are unique feature of the Canadian Shield. The hills are located in northern Saskatchewan and border Lake Athabasca ...
The Athabasca oil sands, along with the nearby Peace River and Cold Lake deposits oil sand deposits lie under 141,000 square kilometres (54,000 sq mi) of boreal forest and muskeg (peat bogs) according to Government of Alberta's Ministry of Energy, [34] Alberta Energy Regulator (AER) and the Canadian Association of Petroleum Producers (CAPP).
Fields in northern Alberta include four major deposits which underlie almost 70,000 square kilometres of land. The volume of bitumen in those sands dwarfs the light oil reserves of the entire Middle East. One of those deposits, the Athabasca oil sands, is the world's largest known crude oil resource.
Whereas the Athabasca oil sands lie close enough to the surface that the sand can be scooped up in open-pit mines, and brought to a central location for processing, the Peace River deposits are considered too deep, and are exploited in situ using steam-assisted gravity drainage (SAGD) and Cold Heavy Oil Production with Sand (CHOPS).

Norway's Equinor said on Wednesday it has sold its stake in Athabasca Oil, a Canadian firm producing carbon-intensive oil sands. Majority state-owned Equinor sold 100 million shares, representing ...
The Athabasca Basin is a region in the Canadian Shield of northern Saskatchewan and Alberta, Canada. It is best known as the world's leading source of high-grade uranium and currently supplies about 20% of the world's uranium. [1] The basin is located just to the south of Lake Athabasca, west of Wollaston Lake, and encloses almost all of Cree ...
