Oil sands, tar sands, crude bitumen, or bituminous sands, are a type of unconventional petroleum deposit. Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, soaked with bitumen, a dense and extremely viscous form of petroleum.
The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen, a heavy and viscous form of petroleum, located 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.
BP Canada was a Canadian petroleum company and subsidiary of British Petroleum that existed between 1955 and 1992. The name refers to a group of companies that engaged in various segments of the petroleum industry lifecycle. BP entered the Canadian market in October 1953, when it purchased a 23 percent stake in the Triad Oil Company. In 1955, BP formed a Canadian subsidiary, based in Montreal, called BP Canada Limited. The company began acquiring retail stations in Ontario and Quebec and in 1957 started construction on a refinery in Montreal. By the end of the 1950s BP Canada was a fully-integrated operation. In 1964, it acquired from Cities Service the Oakville Refinery, and then expanded its operations significantly in 1971 when it acquired Supertest Petroleum.
Suncor Energy is a Canadian integrated energy company based in Calgary, Alberta. It specializes in production of synthetic crude from oil sands. In the 2020 Forbes Global 2000, Suncor Energy was ranked as the 48th-largest public company in the world.
Syncrude Canada Ltd. is one of the world's largest producers of synthetic crude oil from oil sands and the largest single source producer in Canada. It is located just outside Fort McMurray in the Athabasca Oil Sands, and has a nameplate capacity of 350,000 barrels per day (56,000 m3/d) of oil, equivalent to about 13% of Canada's consumption. It has approximately 5.1 billion barrels (810,000,000 m3) of proven and probable reserves situated on 8 leases over 3 contiguous sites. Including fully realized prospective reserves, current production capacity could be sustained for well over 90 years.
Steam-assisted gravity drainage is an enhanced oil recovery technology for producing heavy crude oil and bitumen. It is an advanced form of steam stimulation in which a pair of horizontal wells are drilled into the oil reservoir, one a few metres above the other. High pressure steam is continuously injected into the upper wellbore to heat the oil and reduce its viscosity, causing the heated oil to drain into the lower wellbore, where it is pumped out. Dr. Roger Butler, engineer at Imperial Oil from 1955 to 1982, invented the steam assisted gravity drainage (SAGD) process in the 1970s. Butler "developed the concept of using horizontal pairs of wells and injected steam to develop certain deposits of bitumen considered too deep for mining". In 1983 Butler became director of technical programs for the Alberta Oil Sands Technology and Research Authority (AOSTRA), a crown corporation created by Alberta Premier Lougheed to promote new technologies for oil sands and heavy crude oil production. AOSTRA quickly supported SAGD as a promising innovation in oil sands extraction technology.
Connacher Oil and Gas Limited is a Calgary-based exploration, development and production company active in the production and sale of bitumen in the Athabasca oil sands region. Connacher's shares used to trade on the Toronto Stock Exchange, but it was de-listed in 2016, after filing for insolvency.

Canada's oil sands and heavy oil resources are among the world's great petroleum deposits. They include the vast oil sands of northern Alberta, and the heavy oil reservoirs that surround the small city of Lloydminster, which sits on the border between Alberta and Saskatchewan. The extent of these resources is well known, but better technologies to produce oil from them are still being developed.
The Kearl Oil Sands Project is an oil sands mine in the Athabasca Oil Sands region at the Kearl Lake area, about 70 kilometres (43 mi) north of Fort McMurray in Alberta, Canada that is operated by the 143-year old Calgary, Alberta-headquartered Imperial Oil Limited—one of the largest integrated oil companies in Canada. Kearl is owned by Imperial Oil and is controlled by Imperial's parent company, ExxonMobil—an American multinational that is one of the largest in the world.
Albian Sands Energy Inc. is the operator of the Muskeg River Mine and Jack Pine Mine, an oil sands mining project located 75 kilometres (47 mi) north of Fort McMurray, Alberta, Canada. It is a joint venture between Shell Canada (10%), CNRL (70%) and Chevron Canada (20%). The company's legal headquarters are located in the Shell Centre in Calgary, Alberta. Albian Sands got its name from the Albian Boreal Sea which, during the Albian stage of the Cretaceous, moved over the McMurray sands and deposited a blanket of marine shale on its floor which trapped the hydrocarbons of the McMurray Formation. The oil sands resources of the Muskeg River Mine are a legacy of the Albian Sea.
Although there are numerous oil companies operating in Canada, as of 2009, the majority of production, refining and marketing was done by fewer than 20 of them. According to the 2013 edition of Forbes Global 2000, canoils.com and any other list that emphasizes market capitalization and revenue when sizing up companies, as of March 31, 2014 these are the largest Canada-based oil and gas companies.
The Long Lake oil sands upgrader project is an in situ oil extraction project near Anzac, Alberta, 40 km (25 mi) southeast of Fort McMurray in the Athabasca oil sands region of Alberta.
Canadian Natural Resources Limited, or CNRL or Canadian Natural is a senior Canadian oil and natural gas company that operates primarily in the Western Canadian provinces of British Columbia, Alberta, Saskatchewan, and Manitoba, with offshore operations in the United Kingdom sector of the North Sea, and offshore Côte d'Ivoire and Gabon. The company, which is headquartered in Calgary, Alberta, has the largest undeveloped base in the Western Canadian Sedimentary Basin. It is the largest independent producer of natural gas in Western Canada and the largest producer of heavy crude oil in Canada.
Bitumount is an abandoned industrial site on the east bank of the Athabasca River about 90 kilometres (60 mi) north of Fort McMurray in northeastern Alberta, Canada. Between 1925 and the 1950s, it was the site of early attempts to extract bitumen from the Athabasca oil sands that contributed to the development of commercially viable extraction processes. The site closed permanently in 1958. Some of the structures at Bitumont were declared Provincial Historic Resources in 1974. As of 2017, the buildings are deteriorating.
Laricina Energy Ltd. was a private Canadian oil producing company engaged in exploration in North-Eastern Alberta. The company targeted oil sands opportunities outside of the Athabasca mining area and was focusing on in situ plays in the Grosmont and Grand Rapids formations. Its headquarters were located in Calgary, Alberta, Canada.
Horizon Oil Sands is an oil sands mining and upgrading project in Bitumount, Alberta, Canada. The project includes a surface oil sands mining and bitumen extraction plant, complemented by on-site bitumen upgrading with associated infrastructure.
Bitumen froth treatment is a process used in the Athabasca oil sands (AOS) bitumen recovery operations to remove fine inorganics—water and mineral particles—from bitumen froth, by diluting the bitumen with a light hydrocarbon solvent—either naphthenic or paraffinic—to reduce the viscosity of the froth and to remove contaminants that were not removed in previous water-based gravity recovery phases. Bitumen with a high viscosity or with too many contaminants, is not suitable for transporting through pipelines or refining. The original and conventional naphthenic froth treatment (NFT) uses a naphtha solvent with the addition of chemicals. Paraffinic Solvent Froth Treatment (PSFT), which was first used commercially in the Albian Sands in the early 2000s, results in a cleaner bitumen with lower levels of contaminates, such as water and mineral solids. Following froth treatments, bitumen can be further upgraded using "heat to produce synthetic crude oil by means of a coker unit."
The Alberta Energy Company Ltd. was a Canadian independent petroleum company that existed from 1973 to 2002. The AEC was created by the Government of Alberta under Premier Peter Lougheed as a mechanism for Albertans to invest in the Syncrude oil sands project. Besides its participation in Syncrude, the AEC also received the rights to produce gas in the Suffield Block. The company was established as a mixed enterprise and at its inception was half owned by the provincial Crown and half owned by the public. A restrictive charter, which prevented individual shareholders from acquiring more than one percent of the company and mandated directors be residents of Alberta, ensured control remained within the province. Until 1982, the company was barred from participation in conventional oil and gas exploration, but after that time was given the right to compete with private companies in that area. In 1983 the government began to decrease its equity, and in 1993 divested of its remaining shares.
The Albertan petroleum industry has had massive, social, economical, political, cultural, and demographic influences on the province of Alberta during the 20th century and 21st century, especially during the second half of the 20th century. Oil and gas replaced Agriculture, and ranching as the primary industry and resulted in the province becoming one of the richest in the country. Nationally, the discovery allowed Canada to become self-sufficient within a decade and ultimately a major exporter of oil. Most of its oil production came from its enormous oil sands deposits, whose production has been steadily rising in recent years. It has produced only 5% of its oil sands, and its remaining oil sands reserves represent 98% of Canada's established oil reserves. The issue of the control of oil has been the main conflict between the provincial government and the federal government, with the issue of oil defining the provincial-federal relationship at every level. The petroleum industry in Alberta has been one of the main factors that have contributed to Western alienation, and Alberta separatism, especially during the 1980s when the federal government under the control of Pierre Trudeau crippled the prospering Albertan economy through the National Energy Program.
