Abstract

Summary

Full-waveform inversion (FWI) is increasingly becoming a standard tool to resolve the overburden in shallow water surveys. However, for a simple initial model, applying FWI efficiently due to cycle skipping and local minimum issues has been a major problem until recently. The advent of Adjustive FWI helps mitigate the half-wavelength criteria, facilitating an early start to the depth model building workflow parallel with the time processing sequence. We present a case study using Adjustive FWI that could minimize the impact on turnaround time, enabling the application of optimized workflow, even for the towed-streamer surveys where no good legacy model exists.
