Extracting geological information directly from high-resolution full-waveform inversion velocity models - a case study from offshore Trinidad

This paper focusses on improving the seismic image on a dataset from offshore Trinidad; Tobago by using full-waveform inversion (FWI) to refine the shallow velocities and also describes geological information that can be inferred directly from the resulting velocity model. In the first half of the paper the geology of the region is introduced, then the imaging issues, before describing the FWI methodology and results. The second half of the paper discusses interpretational aspects of the FWI velocity model and highlights its use in a blind pore pressure prediction (PPP) test of well data.
