CNOOC Petroleum North America ULC, formerly known as Nexen, is a Canadian oil and gas company based in Calgary, Alberta.

Originally the Canadian subsidiary of US-based Occidental Petroleum (known as Canadian Occidental Petroleum or CanOxy), it became an independent company, Nexen, in 2000. Nexen was acquired by Hong Kong–based CNOOC Limited in 2013, and was rebranded under the current name at the end of 2018.

It had three growth strategies as of 2013: oil sands and shale gas in western Canada as well as conventional exploration and development primarily in the North Sea, offshore in West Africa, and deepwater exploration in the Gulf of Mexico.
