Seismic interferometry by crosscorrelation and by multidimensional deconvolution: a systematic comparison
Seismic interferometry, also known as Green’s function retrieval by crosscorrelation, has a wide range of applications, ranging from surface-wave tomography using ambient noise, to creating virtual sources for improved reflection seismology. Despite its successful applications, the crosscorrelation approach also has its limitations. The main underlying assumptions are that the medium is lossles...

متن کاملSeismic Interferometry by Deconvolution: Theory and Examples
Seismic interferometry is a field of growing interest in exploration seismology. In this paper we provide the theoretical basis for performing interferometry by deconvolution. We argue that for arbitrarily complicated models, deconvolution interferometry gives the causal scattering response between any two receivers. Interferometry by cross-correlation, on the other hand, gives both causal and ...
متن کاملFull waveform inversion of crosswell seismic data using automatic differentiation
Full waveform inversion (FWI) is an effective and efficient data-fitting technique that has been widely used to produce accurate estimation of model parameters in Geophysics. The efficiency and accuracy of FWI are determined by the three main components: numerical solution for forward problem, gradient calculation and model update which usually involves the optimization method. The success of t...
متن کاملDistribution of noise sources for seismic interferometry
S U M M A R Y We demonstrate that the distribution of seismic noise sources affects the accuracy of Green’s function estimates and therefore isotropic and anisotropic tomographic inversions for both velocity and attenuation. We compare three methods for estimating seismic noise source distributions and quantify the potential error in phase velocity, azimuthal anisotropy and attenuation estimate...
