CO₂ Sequestration

Here's How it Works

1. Collecting waste emissions

   At Weyburn, we purchase CO₂ from the Boundary Dam Power Station in Estevan, Saskatchewan, and the Great Plains Synfuels plant in North Dakota. At Joffre, we purchase CO₂ from the NOVA Chemicals' Joffre manufacturing facility in central Alberta. Without these two operations, the majority of the CO₂ would otherwise be released to atmosphere.

   2.0 Million Tonnes of CO₂

   are sequestered each year (equivalent to 3,125 square kilometers of mature trees growing for one year).

2. Safe Injection of CO₂

   We inject CO₂ at high pressure into the producing formation 1,500 metres underground. Injecting CO₂ deep underground safely stores carbon.

   3X1,500 metres is equivalent to three times the height of the CN Tower in Toronto.

3. Sustainable Oil Production

   The CO₂ acts likes a solvent to flush otherwise unrecoverable oil from pores in the rock. This results in incremental oil production that could not be achieved with conventional means.

   

4. Extracting Valuable Products

   At the surface, oil and natural gas liquids are extracted for sale. The CO₂ produced during oil recovery is returned to the reservoir so that all injected CO₂ is permanently stored deep underground.
