NGMA Cooper and Eromanga Basins Products

Regional seismic horizon maps

PIRSA, in conjunction with AGSO (Geoscience Australia) and the Queensland, New South Wales and Northern Territory government agencies merged data for three key seismic horizons to provide a complete regional (national) view of the structure of the Cooper and Eromanga Basins.

This project was completed in 1997/98 as part of the National Geoscience Mapping Accord (NGMA) and was a natural extension of the C-P-Z Mapping Project completed by PIRSA at the same time for the South Australian sector of the Cooper Basin area (see Cooper Basin C-P-Z Maps) and Eromanga Basin (see Eromanga Basin Seismic Maps).

Compilation was based on available seismic profile data, various company interpretations, other open file industry data, well tops and borehole data.

Final data products include Time maps (P and Z horizons), Depth maps (C, P, and Z horizons) and Isopachs (C-P, P-Z and C-Z) as well as grids and contour data for these horizons. All data has been updated to the GDA 94 reference datum in 2001 and are now available for free on DVD.

Examples of colour-contoured depth map outputs are provided below, with georeferenced TIFF images available as free downloadable files.

Cooper Basin geohistory

An interactive CD-ROM presents interactive geohistory models of the regional burial, thermal and hydrocarbon maturation and expulsion history of the Cooper and Eromanga Basins. These models are based on a comprehensive geohistory analysis undertaken by Geoscience Australia (GA), Primary Industries and Resources, South Australia (PIRSA), the Queensland Geological Survey and Burytech Pty Ltd as part of a National Geological Mapping Accord (NGMA) project. 

This package is available on the Cooper & Eromanga Consolidated Data Package. To order a free copy of this DVD, please visit the Cooper & Eromanga Consolidated Data Package web page.

Organic geochemistry database

A comprehensive organic geochemistry database is available at Geoscience Australia. The OZCHEM National Whole Rock Geochemistry data is a database of whole-rock and stream-sediment geochemistry for samples that are mainly from Australia, Antarctica, Papua New Guinea and the Solomon Islands. Both major and trace element analyses are included.
