Abstract
There remains considerable uncertainty regarding the location, timing and availability of CO2 storage sites in both southeast Queensland and New South Wales. In New South Wales, the main issues relate to the lack of recent or reliable valid geological information that would permit a complete and comprehensive evaluation. Some sedimentary basins appear to contain potential storage reservoirs although they have low permeabilities, and are therefore likely to have low injection rates. In southeast Queensland, recent work has indicated that in some parts of the Bowen and Surat basins CO2 storage is likely to compete with other resources such as groundwater and hydrocarbons. However, current research on the potential storage in deeper saline formations in the southern and western Bowen Basin has provided encouraging results. Storage in deeper stratigraphic units in the central western part of the basin will rely on injection in low permeability formations, and more correlation work is required to define generally narrow storage targets. The Wunger Ridge, in the southern Bowen Basin, however, has promise with both significant storage potential and relatively low geological risk. One area in which there is some potential in both New South Wales and southeast Queensland is CO2 storage in coal seams, as close technical and economic relationships exist between coal bed methane (CBM) field development and operations and CO2 storage. Substantial collaborative research is still required in this area and is currently a focus of the CO2CRC activities
