Advanced computing facilities accelerate the research in highly computational seismic imaging techniques (full-waveform tomography (FWT) and migration) that play a vital role in hydrocarbon exploration. We have carried out a synthetic study to understand the practical intricacies of FWT for its successful application to field seismic data by choosing different strategies. The results show that the high-resolution features, which are missing from the conventional traveltime tomography, are well imaged by the FWT. Further, frequency overlapping is more suitable than discrete frequencies without overlapping for FWT in obtaining reasonable results from multiscale imaging.
