IEAGHG are pleased to announce our next webinar ‘CO2 Storage Efficiency in Deep Saline Formations’ presented by James Craig from IEAGHG.
The success of large-scale CCS will depend on access to deep saline formations (DSFs) that have the potential for extensive and secure CO2 storage. Although these formations occur in several basins across the world and cover areas of thousands of kilometres their storage potential is not well constrained and often based on very approximate pore volume estimates. IEAGHG have commission two complementary studies which have modelled CO2 storage capacity in DSFs based on dynamic conditions to improve estimated storage capacity. The first study modelled the capacity of CO2 storage within two different deep saline aquifers the Minnelusa Formation from the Powder River Basin in North America and the Qingshankou-Yaojia Formations from the Songliao Basin of north-east China. The study modelled the capacity of injected CO2 of these formations under different dynamic conditions and compared these values with the theoretical capacity based purely on pore space. The study assumed that continuous injection could occur over 2,000 years. The second study compared the Minnelusa Formation with the Bunter formation in the UK sector of the North Sea, but over much smaller areas and over a more realistic period of 50 years. This webinar will present a summary of these studies.
This will be held on Wednesday 9th August at 2pm (BST).
