Regional Three-Dimensional Geological Model for the Beetaloo Sub-basin

Abstract

This dataset contains the integrated surfaces form a three-dimensional geological model that was used as a visualisation tool in assessing the structural and stratigraphic framework of the Beetaloo GBA region and assisted in assessing the unconventional gas resource prospectivity and potential impacts associated with their development. These surfaces and can be accessed using most 3D-software packages.

History

Orr et al. (2020) published regional three-dimensional depth and isochore maps for key stratigraphic horizons of the Beetaloo Sub-basin and overlying Paleozoic (Georgina/Wise/Daly) and Mesozoic (Carpentaria) basins. These maps are based on: published depth maps of Frogtech Geoscience (2018a; 2018b), Department of Environment and Natural Resources (NT) (2018a; 2018b), Randal (1973), Hutchinson et al. (2008); seismic interpretation of Williams (2019), and; additional modelled surfaces based on formation top picks contained in well completion reports (Northern Territory Government, 2018). For full details on the inputs and methods used to compile the three-dimensional model refer to Orr et al. (2020).
