Between 3 May 2012 to 24 June 2012 Geoscience Australia undertook two major surveys off the coast of the Northern Territory in the Petrel Sub-Basin. The data acquisition was funded through the National Low Emissions Coal Initiative (NLECI) and the Petrel Sub-basin was selected in particular as it has been identified as a prospective area for CO2 storage. One of these surveys, GA336 acquired 4091 kilometres of 2D seismic reflection data. Following on from the completion of the seismic processing of this data was further investigative work investigative work such as this analysis. Four prime lines, GA336-107, 110, 205 and 207 along with the well logs, Flat-Top1, Petrel 1A and Petrel 4 were selected for further 2D Simultaneous Inversion and Rock Physics Modelling. Previous Pre Stack Depth Migration had been undertaken on these lines and the PSDM Angle Stacks were imported along with the relevant horizon interpretation into the Jason integration algorithms.
