Ben Rostron from the University of Alberta kicked off this session on geological CO2 storage with a talk on the Characterisation of the Aquistore CO2 Project Storage Site in Saskatchewan, Canada. For site characterisation alone, over 18,000 geophones were used at the Aquistore project and, excitingly, they are ready to start CO2 injection. Marcia Couëslan (Schlumberger Carbon Services) presented the Decatur Project integrated reservoir monitoring programme and noted that they are confident that CO2 is being contained in the Mt. Simon Formation. The third speaker in this session, Andrew Cavanagh, (Statoil) talked about the new and extended Sleipner Benchmark Model that challenges reservoir simulations and manages expectations on how the CO2 plume will behave.  Seismic Monitoring has allowed for significant improvements in understanding CO2 flow dynamics and Statoil have recognised a very strong interaction between the CO2 plume and local geology – something seen, not only at Sleipner, but also at Snøvhit and In Salah (among other projects). The new benchmark model will be available soon on the IEAGHG website at www.ieaghg.org. Keep checking the site for updates. Anne Gaelle Bader (BRGM) presented on evaluation of CO2 Storage Capacity in deep-saline aquifers of the Paris Basin and Jinfeng Ma (Northwest University) presented a detailed update on the 2nd year of injection, measurement, monitoring and verification at the Jingbian CCS Project in China. Storage Case Studies (2) is currently underway in Room 9 ABC of the Convention Center.
