Potential shale gas bearing basins in South Australia are primarily dominated by thermogenic play types and span the Neoproterozoic to Cretaceous. Whilst only several companies (Beach Energy, Santos & Stuart Petroleum) have recently commenced exploring for shale gas in the Permian Cooper Basin, strong gas shows have been routinely observed and recorded in thick shale since exploration commenced in the basin in 1959.
Outside the Cooper Basin, thick Permian shales of the Arckaringa Basin have moderate shale gas potential with deeper, yet to intersected sequences in the Phillipson and
Boothanna troughs providing potential for more mature shales.
Shale sequences within the Crayfish Subgroup of the Otway Basin, in particular the shale dominant Laira Formation, is expected to have good shale gas potential in the deeper portions of the basin.
Shale gas has the potential to rival CSM in eastern Australia, and its potential is now being explored in South Australia.
