Overview
Canadian Natural Resources Limited, commonly known as Canadian Natural or CNRL, is a Canadian oil and natural gas company headquartered in Calgary, Alberta. It explores for, develops, produces, processes, and transports crude oil, synthetic crude, bitumen, natural gas, and natural gas liquids. Its principal operating base is the Western Canadian Sedimentary Basin, spanning British Columbia, Alberta, Saskatchewan, and Manitoba, complemented by offshore production in the United Kingdom sector of the North Sea and offshore Côte d’Ivoire and Gabon. The company is particularly identified with large-scale oil-sands production in northern Alberta. Its Horizon Oil Sands operation, located north of Fort McMurray, combines surface mining, bitumen extraction, upgrading, and supporting infrastructure. Canadian Natural also operates the Primrose and Pelican Lake heavy-oil assets and holds a significant interest in the Athabasca Oil Sands Project. These assets give the company a substantial position in Canadian heavy crude and synthetic crude production, while its conventional portfolio provides natural gas, light and medium crude oil, and natural gas liquids. Canadian Natural began in 1973 as AEX Minerals Corporation and adopted its present name in 1975. Its growth was driven by a combination of internal development and acquisitions. During the 1990s and 2000s it expanded its Canadian land position and production base through transactions involving BP Amoco's Canadian assets, Ranger Oil, Rio Alto, Petrovera Resources, and Anadarko Petroleum's Canadian operations. It later acquired conventional Canadian assets from Devon Energy and expanded its oil-sands position through the purchase of Royal Dutch Shell's Canadian oil-sands interests and related infrastructure. The company also acquired the Joslyn oil-sands project and Laricina Energy's assets. Canadian Natural's business model is diversified across resource types and project stages. In addition to exploration and production, it owns or operates pipeline systems, participates in electricity cogeneration, and holds a 50 percent interest in the North West Redwater Partnership. The company's oil-sands production is relatively capital intensive but is based on long-life reserves, while its conventional and offshore activities provide geographic and product diversity. Its production profile has historically been weighted toward petroleum and natural gas liquids rather than natural gas alone. The company is an important participant in Canada's energy sector and a major producer of heavy crude oil. Its scale also places it at the center of debates concerning oil-sands emissions, pipeline safety, land disturbance, water management, and the economic role of petroleum production. Canadian Natural remains an active publicly listed company under the CNQ ticker, with operations concentrated in Canada and selected offshore jurisdictions.
History
Canadian Natural Resources was established on 7 November 1973 as AEX Minerals Corporation. It adopted the Canadian Natural Resources name in 1975 and developed from a Canadian exploration and production business into a large, diversified petroleum company. The company's expansion accelerated through a sequence of asset purchases and corporate transactions. In 1998 it sold land to Remington Energy for C$127.5 million. In 1999, Canadian Natural and Penn West Petroleum acquired Canadian assets formerly held by BP Amoco. In 2000, Canadian Natural purchased Ranger Oil for C$1.08 billion, adding a substantial production and reserve base. In 2002, it acquired Rio Alto in a transaction valued at approximately $2.4 billion. In February 2004, it acquired Petrovera Resources, a joint venture associated with Encana and ConocoPhillips. Canadian Natural sanctioned the Horizon Oil Sands project in February 2005. The northern Alberta development combined surface mining and bitumen extraction with an upgrader capable of producing synthetic crude. Production began in early 2009. Horizon became the company's defining oil-sands asset and a foundation for its long-life heavy-oil strategy. In September 2006, Canadian Natural acquired the Canadian operations of Anadarko Petroleum for US$4.1 billion. The transaction strengthened its Canadian conventional oil and gas portfolio and expanded its resource base in the Western Canadian Sedimentary Basin. In April 2014, it agreed to acquire Devon Energy's conventional Canadian assets for C$3.125 billion, further increasing its domestic scale. A major strategic turning point came in 2017, when Canadian Natural acquired Royal Dutch Shell's Canadian oil-sands assets, including a 70 percent working interest in the Athabasca Oil Sands Project. The consideration included $5.3 billion in cash and 97,560,975 Canadian Natural shares; the shares were sold in 2018. The transaction significantly increased Canadian Natural's oil-sands production and reserve base. In August 2018, it acquired the idled Joslyn oil-sands project from Total and its partners. In September of the same year, it acquired Laricina Energy for $46 million. In June 2019, it acquired Devon Energy's remaining Canadian assets. Alongside upstream production, Canadian Natural developed associated infrastructure and energy interests. The company owns and operates two pipeline systems, operates a cogeneration facility, and owns half of the North West Redwater Partnership. Its offshore portfolio includes production in the United Kingdom sector of the North Sea and offshore Côte d'Ivoire and Gabon, while its principal land-based operations remain in western Canada. The company's history has also included operational incidents. A Horizon construction tank collapse in 2007 caused two fatalities and serious injuries. Regulators investigated seepage at Primrose East in 2013, and pipeline spills occurred near Slave Lake and Red Earth Creek in 2014. These events contributed to public and regulatory scrutiny of the environmental and safety risks associated with oil-sands and pipeline operations. Canadian Natural is now one of Canada's largest independent oil and gas producers. Its portfolio is weighted toward petroleum and natural gas liquids, particularly synthetic crude and heavy oil, but it also remains a major Western Canadian natural-gas producer. Its current identity combines a large domestic resource base, long-life oil-sands assets, conventional production, offshore operations, and supporting midstream infrastructure.

Upgraded oil-sands product · 2009
Synthetic crude oil
Synthetic crude is produced by mining oil-sands ore, extracting bitumen, and upgrading it into a lighter, refinery-compatible crude stream. Horizon is the company's principal integrated mining and upgrading operation and has historically made synthetic crude the largest component of its production mix.
