Weyburn
Located in southeast Saskatchewan, Weyburn is currently producing 27,000 gross barrels per day. A prolific oilfield, it has produced for more than 50 years due to technology advances, most recently CO2 flood. Since the start of CO2 injection in 2000, the cumulative CO2 stored to date at Weyburn is equal to taking 3.7 million cars off the road. It is recognized as the world's largest geological CO2 storage project.

Third-party studies confirm CO2 used in our Weyburn operations remains underground
Cenovus commissioned a site assessment to evaluate whether carbon dioxide (CO2) in the soil and other reported issues at a nearby property were a result of our enhanced oil recovery operations.
Third-party research studies have confirmed the CO2 we inject at our Weyburn operation is not linked to high CO2 concentrations in the soil. The full reports are listed below. A news release was also issued.

IEAGHG Weyburn-Midale CO2 Monitoring and Storage Project
The Weyburn project is the site of a world-scale research initiative operated under the auspices of the IEAGHG, which studies the storage of CO2 in an oil reservoir. The goal for the final phase of this research initiative is to document best practices to guide future CO2 storage projects.
