Abstract

We discuss an application of the method of integral equations (IE) to seismic 3D full-waveform inversion. It was demonstrated, that using an iterative solver with efficient matrix-vector multiplication, implemented via fast Fourier transform, allows utilization of the IE method to solve large problems. We applied the quasi-analytical (QA) and Born approximations to computation of Fréchet derivatives in order to reduce calculation time. To compare the two approaches, we inverted synthetic acoustic field of a complex 3D model. It was shown, that the use of the QA approximation improves convergence of the iterative process. These results indicate that the method of IE, in conjunction with an approximate method for calculation of Fréchet derivatives, is very promising for building fast and accurate inversion algorithms for seismic data.
