Abstract

Mineral trapping of CO ₂ by precipitation of carbonate minerals is seen as the most permanent and secure mechanism of CO ₂ storage. We have investigated mineral trapping in CO ₂ -rich siliciclastic reservoirs of the Upper Miocene age in the Yinggehai Basin (South China Sea) and used nearby CO ₂ -poor reservoirs of similar age as benchmarks for the analysis. Within the reservoir, the CO ₂ has triggered the reaction from calcite plus chlorite to ankerite plus kaolinite, which traps 5 mol of CO ₂ per mole of chlorite. Geochemical modelling shows that the total amount of permanently trapped CO ₂ is approximately one half of the CO ₂ in the newly formed ankerite. Caprock mineralogy shows that CO ₂ leakage has occurred and CO ₂ has migrated into the shale-rich caprock, but without loss of caprock integrity.
