oa Multi-Parameter Waveform Inversion Using Broadband Data from the North West Shelf of Western Australia

We present a multi-disciplinary approach to determine overburden anisotropy on the North West Shelf of Australia. Beginning with a synthetic dataset we demonstrate the significance of incorrect overburden anisotropy in seismic imaging and develop a workflow for solving the problem. This is followed by application of our workflow to a field case study involving the use of geological inference, log-based rock property relationships, and surface seismic data. Comparisons are made between applying the workflow using conventional and broadband streamer datasets acquired over the same area.
