CO2 Storage Capacity Assessment of Deep Saline Aquifers in the Mozambique Basin

摘要: Abstract This study is the first of its kind that made an assessment theoretical storage capacity within deep saline aquifers in Mozambique Basin. An integrated approach involved geographic information systems analysis and field data was adopted to estimate capacity. Geological characterization conducted based on available geological cross-sections supported by well stratigraphy from well-logs. Four separate depth ranges 800 m 3,500 below surface were recognized basin, each having own sealing shale layers. The low- high-end CO 2 for rock formations estimated using volumetric approach. use GIS tools has resulted more robust estimates which reduced spatial uncertainty thus constrained estimations. It also avoided unrealistic extrapolation throughout while promoting a proper accounting possibility store multiple overlaying formations. We believe digital atlas developed should provide basis further work reduce support policy makers future planning CCS projects country.
