Thank you, the details comments on those figures have been followed and new figures are provided Helium measurements from groundwater samples.
Seismic reflection 2D lines (1989-2015). 8500 km. Interpretation of shallow horizons and faults using all publicly available geological and geophysical data of the Beetaloo region. Fault polygons defined for five horizons. Depth conversion using check-shot velocities from 26 wells. See comments to Figure 4. The depth maps provided in Figure 5 should be supplemented by isochore maps for the rock volumes between pairs of mapped reflectors. See also comments to Figure 7.
