A first assessment of potential stratigraphic traps for geological storage of CO2 in the Durban Basin, South Africa
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 ∼327 Mt CO2 could potentially be stored in two laterally extensive shelf sand sequences, with a further potential for ∼464 Mt CO2 storage in basin floor fan systems in the distal basin.
