Canadian Natural Resources Limited, or CNRL or Canadian Natural, is an oil and gas exploration, development and production company with its corporate head office in Calgary, Alberta. Along with its core area Western Canadian Sedimentary Basin (WCSB),, CNRL also has North Sea and offshore West Africa fields. By 2011, with a production of 121,000 barrels (19,200 m), CNRL was Canada's largest oil company and Canada's "single biggest conventional heavy oil producer." By 2009 CNRL ranked number 251 on the Forbes Global 2000 list.
"The Company targets primary, secondary and tertiary recovery of heavy crude oil and thermal in situ recovery of bitumen. Canadian Natural’s primary heavy crude oil operations are centered on the Alberta – Saskatchewan border, near the city of Lloydminster. The Company’s extensive and dominant land base allows them to conduct large scale drilling and development programs while minimizing capital cost requirements. Costs are further managed through owning and operating centralized treating and sand handling facilities, maximizing their utilization and using their size to achieve economies of scale. Infrastructure includes five crude oil processing facilities and four salt caverns for solids disposal. Ownership of the ECHO sales pipeline allows Canadian Natural to be the only producer capable of delivering undiluted heavy crude oil into blending facilities at Hardisty, Alberta."
"Pelican Lake is a large, shallow crude oil pool in the Northern Plains core region; estimated to contain 4.1 billion barrels of original oil in place on Canadian Natural land. Although initially developed for primary production, the Company started converting portions of the field to waterflood in 2004, resulting in a significant production increase which reversed the previous three years of production decline. Building on that success, the Company began testing polymer flooding in 2005. This enhanced oil recovery technique has proven to be much more effective than waterflooding and as such, the Company is converting more of the field to polymer flood."
