CNOOC International, the international division of CNOOC Limited, is a global energy company with operations in Asia, Africa, the Americas, the Middle East and Europe. Our successful growth as an upstream oil and gas producer has been achieved by consistently finding and developing world-class assets.


Our business is focused on safely exploring and producing from conventional offshore, unconventional and oil sands assets. As part of the CNOOC Group of companies, which span the entire energy supply chain, our size and capability create a competitive advantage that ensures we deliver long-term value.


In Canada, CNOOC International has oil sands assets in Long Lake, located in northern Alberta just south of Fort McMurray, which is a SAGD and partial Upgrader operation with production capacity of 85,000 barrels of bitumen a day. We also have interest in several other oil sands projects, including Hangingstone, operated by Greenfire Resources Operating Corporation and Syncrude’s oil sands mining upgrading facility. In addition to our oil sands business, we have shale gas land in Northeast British Columbia, a power station in Balzac, Alberta, and interest in a wind farm in southern Alberta. Calgary is our regional corporate office for all North America.

7+ years of experience in reservoir characterization and geomodelling, preferably in SAGD or heavy oil operations.
Proficiency in geomodelling software (e.g., Petrel, CMG) and geostatistical techniques.
Strong understanding of static and geocellular reservoir modeling, including property population techniques and spatial heterogeneity representation.
Experience integrating seismic interpretation with reservoir models to improve geological understanding.
Familiarity with well log interpretation, petrophysics, and geomechanical considerations in SAGD operations.
Proficiency with Power BI would be considered an asset.



Desired Skills / Attributes

Displays a strong personal commitment to Health, Safety and Environment (HSE).
Knowledge of dynamic reservoir simulation and history matching techniques.
Experience working with large datasets and automation of workflows.
