Abstract

Summary

Elastic full-waveform inversion of multicomponent seismic data is a powerful tool to simultaneously reconstruct subsurface quantitative parameters, and suffers from the limited frequency components in records, the incomplete survey geometry, and the trade-off effects between different parameters. To deal with this, a well estimation of the inverse Hessian operator is requires. We introduce the truncated Gauss-Newton method in EFWI based on the improved scattering-integral algorithm. We firstly introduce the computation of the gradient vector, and then the implementation of the approximate Hessian operator in a matrix-free conjugate gradient approach. Finally, we present a numerical experiment to prove the effectiveness of this method.
