Underground geological storage of CO 2 ( 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.
