Unconventional Middle Cambrian Petroleum Systems in the Georgina Basin, Australia
Geoscience Australia's systematic evaluation targets the shale gas and oil potential of the ~325,000 sq. km Georgina Basin. The assessment relies on updated stratigraphy, tectonic history, petrography, and petroleum systems modeling, with a focus on geochemistry. For example, a 'hot shale' unit has TOC and HI up to 15.5% and 500 mg hydrocarbons/g TOC, respectively, with maturity ranging from early oil to early dry gas windows.
