Laboratory measurements from field samples of outcrop and analysis of well logs were used to create elastic models of two known reservoirs on the Lennard Shelf in the Canning Basin. Synthetic seismograms were produced using full waveform elastic and viscoelastic modelling techniques to assess the applicability of direct hydrocarbon indicators. When applied to a real 3D dataset significant effort was made to suppress ground roll whilst preserving the underlying signal used in the analysis methods. A method for calculating the intrinsic absorption (Q) between two interfaces showed a strong anomaly associated with a regional anticline coinciding with the Sundown oilfield.
