What Are the Direct (geologic) Sequestration Projects in the PCOR Partnership Region?
CO2 has been sequestered in the subsurface at the Weyburn oil field in Saskatchewan since the late 1990s, and the PCOR Partnership is planning geologic sequestration projects in depleted oil reservoirs, unminable coal seams, and a saltwater reservoir layer deep underground. The Weyburn oil field is the site of an active CO2 flood, a technique of displacing oil by pumping CO2 into oil-bearing formations to improve oil production. Weyburn is also the site of a major international effort, coordinated by the Petroleum Technology Research Centre, located in Regina, Saskatchewan, to assess geologic sequestration practices. The results from Weyburn have demonstrated the site to be safe and secure for sequestration. It is expected that more than 20 million metric tons of CO2 will be successfully sequestered in the Weyburn oil field by 2025.
