Our History as a Successful & Responsible Developer Stretches Back Four Decades
Nexen’s roots may be in Western Canada but today we operate on an international stage. Nexen has grown into a global upstream oil and gas producer by consistently finding and developing significant assets that deliver long-term value.
We partner successfully with governments and supermajors around the globe. We embrace innovation and technology to responsibly and profitably develop resources in some of the world’s most exciting basins. Most importantly, we’ve shown initiative, patience and persistence when it mattered, and have built a company fuelled by deep talent and a passion for what we do.
||WESTERN CANADIAN ROOTS|
Nexen’s origins date back to the formation of Canadian Occidental Petroleum Ltd. (CanadianOxy), a Western Canadian oil and gas producer, in 1971.
||A WORLD-CLASS DISCOVERY|
Our early success in Canada fuelled the company’s first discovery in Yemen in 1990. It was a bold move that tripled our proved plus probable reserves and exceeded expectations by yielding more than a billion barrels of oil.
||DEVELOPING LEGACY ASSETS|
CanadianOxy was renamed Nexen Inc. in 2000 and we embarked on our next growth phase by investing in the Buzzard offshore facility in the UK North Sea and our Long Lake oil sands operation.
||A NEW CHAPTER|
A new chapter in our proud history began when CNOOC Limited acquired Nexen in a US$15.1-billion transaction. Calgary is one of CNOOC Limited's international headquarters.
