13 QUAL I TÉ GÉOPHYSIQUEAPPLIQUÉE Introduction 2 J.-L. Mari, M. Mendes In the geophysics of oil exploration and reservoir studies, the surface seismic method is the most commonly used method to obtain a subsurface model in 2 or 3 dimensions. This method plays an increasingly important role in soil investigations for geotechnical, hydrogeological and site characterization studies regarding seismic hazard issues. This book is neither a basic introduction nor a theoretical study of seismic imaging. Its goal is to provide a practical guide, through the use of examples from the field, to the application of seismic methods to surface imaging. After reviewing the current state of knowledge in seismic propagation, refraction and reflection seismic methods, the book aims to describe how seismic tomography and full waveform inversion methods can be used to obtain seismic images of the subsurface. The book highlights the benefit of combining different seismic methods through various synthetic and field examples.
