Carbon dioxide (CO2) sequestration in deep saline aquifers and formations: Chapter 3

Carbon dioxide (CO₂) capture and sequestration in geologic media is one among many emerging strategies to reduce atmospheric emissions of anthropogenic CO₂. This chapter looks at the potential of deep saline aquifers – based on their capacity and close proximity to large point sources of CO₂ – as repositories for the geologic sequestration of CO₂. The petrochemical characteristics which impact on the suitability of saline aquifers for CO₂ sequestration and the role of coupled geochemical transport models and numerical tools in evaluating site feasibility are also examined. The full-scale commercial CO₂ sequestration project at Sleipner is described together with ongoing pilot and demonstration projects.
