This record comprises largely 160 spreadsheets containing quantitative organic geochemical and
permeability/porosity data from 111 petroleum exploration wells located throughout the Canning
Basin (Fig 1). About half of the geochemical data is from AGSO's Orgchem database (as at 5.5.94);
and it was largely this information that was used to undertake the petroleum systems analysis
described in Kennard et al., (1994). That review, and this database, have been augmented
substantially by geochemical information from well completion reports and other unpublished
company reports that were examined during the compilation of information in Stage II of the Project,
between 1992-4. This information has not been incorporated into Orgchem. The permeability and
porosity data are from individual well completion reports and other unpublished company reports.
