The data used in the compilation of this atlas originate from research conducted by the CO2CRC seals research program and superceded the APCRC seals program. Similar atlases exist in other parts of the world, notably by Shell, Sneider and Reservoirs Inc., and Petrotech. This is the first such atlas to deal specifically with seals and even more specifically, Australian and New Zealand seals.
The seals atlas is primarily based on extensive mercury-injection capillary-pressure (MICP) analyses that have been performed using a state-of-the-art Micromeritics Mercury Porosimeter. The samples included in this atlas are mainly from the research realm, as most commercial work is proprietary. In addition to MICP data, thin sections, x-ray diffraction analysis, grain-size distribution, scanning electron microscopy with energy dispersive x-ray spectroscopy, and shale volume are included.
The hydrocarbon and carbon dioxide seal examples are grouped by basin localities (see location map) and further distinguished by formation, well, then depth if multiple examples were analyzed. Where multiple examples are available, a range of lithologies and MICP data are included in the sample selection.

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.
