Abstract

Summary

In exploration seismology, it is important to construct accurate models of the subsurface properties. One method that can lead to detailed subsurface models is full waveform inversion (FWI). Recent advances in marine acquisition make it possible to acquire extended data sets containing information about direction of seismic waves. These advances, in turn, call for development of new processing algorithms that take advantage of the additional information. In a recent study, an FWI method based on vector data was proposed and the effect of using different types of source — monopole and dipole — was demonstrated. In this paper, we extend this method to include receiver weighting, and further theoretically extend it to the variable density case. We demonstrate the advantages of VFWI on 1D examples.
