Zululand Basin - ZB Raw Data

These datasets were utilised for the evaluation of the potential of the onshore Cretaceous Zululand Basin for geological storage of CO2 as presented in the paper: L.V. Tibane, H. Pöllmann, F. Ndongani, B. Landman, W. Altermann, 2021. Evaluation of the lithofacies, petrography, mineralogy, and geochemistry of the onshore Cretaceous Zululand Basin in South Africa for geological CO2 storage. International Journal of Greenhouse Gas Control. 109, 103364. DOI:10.1016/j.ijggc.2021.103364. H2O-CO2-rock interactions experiments were performed over a period of 4 weeks under simulated in-situ conditions at the temperature of 100 °C and pressure of 100 bar. The data show that the sandstone and siltstone units investigated react with scCO2, causing a slight change in rock porosity and permeability. However, mineralogical, geochemical, geomechanical, and petrophysical characterisations require additional raw data from unweathered fresh drill cores to model the long-term effects of the trap mechanism.
