Cooper Basin C-P-Z Maps

1997 Mapping Programme

Regional mapping was undertaken by PIRSA between 1995 and 1997 to provide explorers with a comprehensive view of the structure of the Cooper Basin. Three key seismic horizons were mapped using existing open file seismic sections and industry interpretations all tied to the extensive network of some 1300 wells in the basin. The horizons mapped were:

  • top Cadna-Owie (C horizon)
  • near-top Permian (P horizon)
  • top Warburton (Z horizon).

These horizons generally divide the basin into the gas prone units of the Permo-Triassic Cooper Basin and the overlying oil prone Jurassic Eromanga Basin. In addition to the C-P-Z horizons maps, another six horizons which divide the stratigraphic section further have been presented based on well data and phantomed on the key interpreted seismic horizons. Horizon maps have been converted to depth and an extensive range of isopach maps have been prepared.

A description of the methods and techniques employed in this mapping project and the horizons interpreted are detailed in the 1998 report, Report on Seismic Mapping Project, Cooper and Eromanga Basins, South Australia, 1995-1997 (PDF - 3.6 MB). Many of the maps contained within this dataset were also included in the original Cooper Basin Folio - Volume 1. 

2002 Update 

All data created during the 1997 regional mapping programme were updated in 2002 to cater for the change in mapping datum from AGD 84 to GDA 94. Some refinements to the original data and maps were made but these were largely minor in nature.

2009 Update

Updates of the 2002 C, P and Z horizon maps, for both time and depth, are now available. Created by PIRSA in 2008/09, these new horizon maps are:

  • based on the original 1997 and updated 2002 mapping;
  • including current company interpretations made available to PIRSA, and
  • is based on Cooper Basin exploration programs since 2000.
The new depth grids have been tied to all available wells at the C, P and Z horizon levels.
