Description
The Mesoproterozoic Beetaloo Sub-basin is a fully concealed sub-basin located approximately 300 km southeast of Katherine. It comprises thick successions of the Roper Group within the McArthur Basin.
The boundary defining the spatial extents of the Beetaloo Sub-basin represents the top Kyalla Formation at a depth of approximately 400 m below topographic surface. The depth to top Kyalla Formation is calculated from the interpretation of 96 seismic lines constrained by 26 wells. The spatial extent of the boundary is further constrained by potential field geophysics.

Data Quality
Lineage:"Top Kyalla Formation was interpreted on seismic lines from the following surveys:
- McArthur Basin 2D SS 1989
- McArthur Basin 2D SS 1990
- McArthur 2D SS 1991
- McArthur Basin 2D SS 1991
- McArthur River Ph I 2D SS 1992
- McArthur River Ph II 2D SS 1992
- Beetaloo Basin 2D SS 2006
- Beetaloo 2D SS 2011
- Beetaloo 2D SS 2012
- Hidden Valley 2D SS 2013
- McArthur 2D SS 2013
Interpretations were constrained using well data and potential field geophysics.
An additional extent was added later based on work presented at the 2021 Annual Geoscience Exploration Seminar, Alice Springs, NT."
Positional Accuracy:Data are interpretative and positional accuracy is influenced by both input datasets and interpretation uncertainty. The quality of the input datasets is considered highly variable. Seismic two-way time to depth conversion accuracy is estimated at 150 m.
Attribute Accuracy:Attribution accuracy is high, accurately reflecting the interpretation.
Logical Consistency:Data is logically consistent for the purposes of the geological interpretation of the spatial extent of the Beetaloo Sub-basin. GIS editing tools were used to check for topology rules. Known topology issues have been identified and will be address in future updates.
