    Abstract

    Underground geological storage of CO2 (GSC) requires a high level of subsurface understanding that is often hindered by a lack of data. This study demonstrates the use of stratigraphic forward modelling (SFM) in generating and characterising a static reservoir model using limited well data, with multiple potential applications within the GSC workflow. Sedsim SFM software was used to create a static model of the Surat Basin, including a high-resolution nested model of the EPQ-7 GSC tenement within the basin. Deposition and burial of the Jurassic Precipice Sandstone, Evergreen Formation and Hutton Sandstone were simulated. Modelling results show a close match with gamma-ray well logs in the tenement area, and the model can be considered a credible model of the subsurface. The Sedsim-predicted formation thicknesses and porosity and permeability distributions meet criteria set for GSC, suggesting that the EPQ-7 tenement may be a prospective GSC location.
