The Perth Basin is a north- to north-northwest-trending, onshore and offshore sedimentary basin extending about 1300 km (808 mi) along the southwestern margin of the Australian continent (Figure 21). This large (172,300 km2; 66,525 mi2), structurally complex basin formed during the separation of Australia and greater India in the Permian to Early Cretaceous. It includes a significant onshore component and extends offshore to the edge of continental crust in water depths of up to 4500 m (14,764 ft) (Marshall et al., 1989; Crostella and Backhouse, 2000; Geoscience Australia, 2009c).

Atlas of Australian and New Zealand Hydrocarbon Seals: Worldwide Analogs for Cap Rocks and Intraformational Barriers in Clastic Depositional Settings
The purpose of this Seals Atlas is to present the microstructural, petrophysical, and geomechanical properties of selected examples of cap rocks and fault seals for use as analogs in the prediction of seal capacity or containment potential. Similar atlases exist; however, this is the first such atlas to focus specifically on the characteristics of cap rocks. The atlas is primarily based on extensive mercury injection capillary pressure (MICP) analyses, but also includes thin section, XRD, grainsize distribution, SEM/EDS, and 'V shale' data. The samples included in this atlas are a result of APCRC and CO2CRC (Cooperative Research Centres) research programs focusing on top and intraformational seals and some fault seals (cataclasites) throughout Australia and New Zealand. The hydrocarbon/carbon dioxide seal examples are grouped by basin localities and further distinguished by formation, well, then depth. Where multiple examples are available, a range of lithologies and MICP data are included in the sample selection. This atlas also can be used in an evaluation of integrated seal potential for prospect risking and reservoir management.
