This work presents a field data application of my recently developed technique for reconstructing production-induced subsurface model changes from time-lapse seismic data using full-waveform inversion (FWI). The technique simultaneously inverts multiple survey vintages with total-variation (TV) regularization of model differences. In this application to Gulf of Mexico, Genesis Field 3D data, we resolve negative velocity changes associated with overburden dilation. The estimated velocity anomalies are consistent with the trajectories of three wells that are known to have failed.
