An Improved Depositional Model for the Organic Rich Shales of the Amungee Member of the Velkerri Formation in the Beetaloo Sub-basin, Northern Territory, Australia

The geology of the Beetaloo Sub-basin, a component part of the thick and geographically extensive greater McArthur Basin, remains relatively poorly described due to limited outcrop, seismic data and well penetrations. Since around 2010, however, there have been approximately 3000 km of 2D seismic data acquired and around 12 wells drilled, targeting the organic-rich shales of the Amungee Member of the Velkerri Formation. These have provided an improved understanding of the geological history of the Beetaloo Sub-basin and of the geology of the Velkerri Formation in particular.
