In this paper, seismic exploration methods are reviewed with a particular emphasis on the
use of the reflection seismology to investigate the subsurface structures and characterize …

Full waveform inversion using the conventional L 2 distance to measure the misfit between
seismograms is known to suffer from cycle skipping. An alternative strategy is proposed in …

Full waveform inversion (FWI) is a powerful method for reconstructing subsurface
parameters from local measurements of the seismic wavefield. This method consists in …

For the last 30 yr, since Tarantola's pioneering theoretical study of waveform inversion,
geophysicists and applied mathematicians have utilized a waveform inversion to delineate …

Since the pioneering work of Tarantola, waveform inversion has emerged as a tool for
estimating velocity models of the subsurface using pre-stack seismic data. The waveform …

We present an extension of the adjoint method that allows us to compute the second
derivatives of seismic data functionals with respect to Earth model parameters. This work is …

A comprehensive validation of 2-D, frequency-domain, acoustic wave-equation tomography
was undertaken in a 'blind test', using third-party, realistic, elastic wave-equation data. The …

Full waveform inversion is a powerful tool for quantitative seismic imaging from wide‐
azimuth seismic data. The method is based on the minimization of the misfit between …

In offshore surveys, the deep crust is generally investigated by traveltime tomography
applied to sparse ocean bottom seismometer data. The inferred velocity models are of …

With the acquisition of wide-aperture seismic data sets, full-waveform inversion is an
attractive method for deriving velocity models. Three-dimensional implementations require …
