چکیده انگلیسی
Within offshore frontier sedimentary basins, legacy data are important tools in basin-scale exploration for potential CO2 storage. We utilise single-channel 2D seismic reflection and well data obtained from the offshore Durban Basin, east coast South Africa, to provide new evidence of reservoir/seal pairs in saline aquifers that may represent potential storage sites for CO2 injection. Multiple, previously undefined and regionally pervasive stratigraphic traps have been mapped through a detailed seismo-sedimentary analysis. These include shelf-bound shallow-marine-sheet and deltaic sandstone packages of Turonian and Maastrichtian age respectively. Coeval with these laterally extensive shelf packages, multiple basin floor fan systems have been identified on the palaeo-slope. We further correlate these systems with analogous hydrocarbon-bearing sequences throughout a large region of the south-east African continental shelf. Using conservative assumptions, we propose that â¼327Â Mt CO2 could potentially be stored in two laterally extensive shelf sand sequences, with a further potential for â¼464Â Mt CO2 storage in basin floor fan systems in the distal basin.
