J.-L. Mari, M. Mendes

This book provides an overview of seismic imaging. It provides a practical guide, through the use of field examples, to the contribution of seismic methods to reser- voir, geotechnical and civil engineering studies. The book is written for students and researchers in geosciences as well as for professionals. We hope that it will posi- tively encourage the reader to evaluate the proposed methodologies for themselves, namely tomography, full waveform inversion, hybrid methods, and integrated approaches, for use on near subsurface datasets.

In each chapter, the reader will find theoretical concepts, practical rules and, above all, actual application examples. For this reason, the book can be used as a text to accompany course lectures or continuing education seminars.

This book aims to promote the exchange of information among geologists, geophys- icists, and engineers in geotechnical fields.

To enable the use the wavefield preconditioner while, at the same time, ensuring that the amplitudes close to the surface are not too high, we modify it such that the values to a
