The IEA Weyburn CO2 Monitoring and Storage Project was a collaborative initiative involving workers from North America and Europe and was co-ordinated by the Petroleum Technology Research Centre (PTRC) in Regina, Canada. The project has studied the geological sequestration of CO2 during a commercial enhanced oil recovery (EOR) operation at the Weyburn oilfield, Saskatchewan, Western Canada. EnCana Resources (formerly PanCanadian Resources) began injecting a 95% pure CO2 stream into the oil reservoir, the Midale Beds, at Weyburn during September 2000. At the conclusion of this EOR operation, it is anticipated that over 20 million tonnes of anthropogenic CO2 will have been permanently and safely sequestered in these Mississippian strata, which are c. 1.4 km underground. Hence, greenhouse gas emissions will have been significantly reduced as part of a cost-effective industrial operation. The principal objective of the monitoring project was to enhance scientific knowledge pertaining to the underground sequestration of CO2 associated with EOR using several different techniques in geoscientific monitoring. Another major strand to this work has been the promotion of international collaboration on carbon management research between scientists in Canada, the USA and Europe. The results from this project will help guide policy makers on carbon management issues. The European project team comprises nine organisations and was co-funded by the European Commission (EC).
