Weyburn

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.
