Project Summary
The South West Hub project is now entering an evaluation stage, aimed at reducing uncertainties related to the distribution of properties of the targeted subsurface formations.
Currently, data is sparse and more confidence is needed is the storage potential for the basin. Ambiguities are particularly evident in the following aspects of the subsurface basin characterisation:
- Diagenetic history of the sediments and how diagenesis affected the pore space and therefore the injectivity and storage potential of the targeted units;
- Current and past nature of the formation fluids and reservoir compartmentalisation between the different fault blocks identified in the subsurface of the SW-Hub;
- Seismic constraints on the petrophysical character of the Lesueur Sandstone;
- Geomechanical properties of the storage reservoir and overlying units.
