During 2009-11 Geoscience Australia completed a petroleum prospectivity study of the offshore northern Perth Basin as part of the Australian Government's Offshore Energy Security Program. A significant component of the program was the acquisition of a regional 2D reflection seismic and potential field survey GA-310 in 2008/09.
Basement in the northern Perth Basin is deep and generally not resolved in the reflection seismic data. This study models the observed gravity in 2.5D along two southwest trending dip-direction reflection seismic transects across WA11-18 to provide insight into the likely sediment thickness and basement topography. Three cases and ten models are examined according to assumptions about possible target depth to basement, and assumptions about Moho depth
