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. The goal of this book is to provide a practical guide, using examples from the field, to the application of seismic methods to surface imaging. After reviewing the current state of knowledge in seismic wave propagation, refraction and reflection seismic methods, the book aims to describe how seismic tomography and fullwave form inversion methods can be used to obtain seismic images of the subsurface. Through various synthetic and field examples, the book highlights the benefit of combining different sets of data: refracted waves with reflected waves, and body waves with surface waves. With field data targeting shallow structures, it shows how more accurate geophysical models can be obtained by using the proposed hybrid methods. Finally, it shows how the integration of seismic data (3D survey and VSP), logging data (acoustic logging) and core measurements, combined with a succession of specific and advanced processing techniques, enables the development of a 3D high resolution geological model in depth. In addition to these examples, the authors provide readers with guidelines to carry out these operations, in terms of acquisition, as well as processing and interpretation. 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, geophysicists, and engineers in geotechnical fields.

In the last two decades a lot of effort has been directed towards methods that have the potential to succeed in imaging complex 3D subsurface structures from multi-coverage seismic data. The necessity of an estimate for the wave propagation velocities, required for transforming the data from the time domain to the depth domain, poses one of the fundamental problems in seismic imaging. Inadequate velocity models distort the final depth image. So-called data-oriented approaches are a class of imaging methods that avoid the explicit parameterisation of a velocity model in the first imaging steps. Instead, the data-oriented approaches parameterise the reflection events in the time domain and try to obtain as much information as possible from the measured data. The extracted information is then used to transform the seismic data into depth. The common-reflection-surface (CRS) stack is one of the data-oriented imaging approaches. This method makes use of second-order traveltime approximations in order to describe seismic reflection events in the time domain. For the processing of data from a 3D acquisition, the traveltime equations can be used as stacking operators to simulate a zero-offset (ZO) volume of high accuracy and high signal-to-noise ratio from multi-coverage prestack data. During the stack, reflection energy from the entire five-dimensional data hyper-volume enters into the construction of one ZO sample. The eight parameters, which express the traveltime approximation for the ZO case, relate to kinematic wavefield attributes. These locally describe the propagation directions and curvatures of specific wavefronts at the Earth's surface which have travelled through the subsurface. Thus, the kinematic wavefield attributes constitute integral quantities of the medium's parameters and are suitable to estimate the properties of the Earth's interior. The accurate determination of the wavefield attributes is, therefore, a crucial step in the CRS processing. In this thesis the derivation of the traveltime approximations is presented. The kinematic wavefield attributes are introduced by means of concepts known from geometrical optics. The determination of the eight kinematic wavefield attributes for the ZO case from 3D multi-coverage seismic data is elaborated. The applications of the attributes to support and facilitate 3D seismic imaging are discussed. In this context emphasis is put on the utilisation of the kinematic wavefield attributes for the 3D CRS stack. The proposed search algorithms are validated on a synthetic data example and have shown to be successful. Finally, the 3D CRS stack is applied to a real marine dataset. In this way the functionality of the search algorithms on complex data is verified. Moreover, the imaging quality of the 3D CRS stack is checked by migrating the simulated ZO volume to depth and comparing the obtained result with the result from a prestack depth migration. The comparison shows that the CRS based result is competitive to the result of the prestack depth migration. Thus, CRS based imaging is an alternative to prestack depth migration due to the good imaging quality and also due to the provided information in form of the kinematic wavefield attributes.

3C seismic applications provide enhanced rock property characterization of the reservoir that can complement P-wave methods. Continued interest in converted P- to S-waves (PS-waves) and vertical seismic profiles (VSPs) has resulted in the steady development of advanced vector wavefield techniques. PS-wave images along with VSP data can be used to help P-wave interpretation of structure in gas obscured zones, of elastic and fluid properties for lithology discrimination from S-wave impedance and density inversion in unconventional reservoirs, and of fracture characterization and stress monitoring from S-wave birefringence (splitting) analysis. The book, which accompanies the 2016 SEG Distinguished Instructor Short Course, presents an overview of 3C seismic theory and practical application: from fundamentals of PS-waves and VSPs, through to acquisition and processing including interpretation techniques. The emphasis is on unique aspects of vector wavefields, anisotropy, and the important relationships that unify S-waves and P-waves. Various applications and case studies demonstrate image benefits from PS-waves, elastic properties and fluid discrimination from joint inversion of amplitude variations with offset/angle (AVO/A), and VSP methods for anisotropic velocity model building and improved reservoir imaging. The book will be of interest to geophysicists, geologists, and engineers, especially those involved with or considering the use of AVO/A inversion, fracture/stress characterization analyses, or interpretation in gas-obscured reservoirs.
