Seismic surveys are subject to many different design criteria, but often the parameters are established based on an outdated view of how data can be acquired and how it will be processed. This book highlights what is possible using modern acquisition methods, techniques, and equipment, and how these may impact seismic survey design and acquisition.

This book introduces simultaneous source technology and helps those who practice it succeed. Although the book does not include all developments, which would have en­tailed a much longer treatise, this work is written through the lens of decades of experiences and allows readers to understand the development of independent simultaneous sourcing. The relationships between data acquisition and data processing are discussed because never before have they been so intertwined as in this area. In addition to describing the underlying technologies, this book also is a user-guide which discusses survey design and acquisition and decribes the sensitivities of the processing algorithms which can allow simultaneous source technology to succeed. The audience for this book includes acquisition and pro­cessing geophysicists who will work with these data as well as those who require only an overview of the state of the art; and, even though they may not need the full technical details, they may want to know the limitations and advantages of using simultaneous sources.

This illustration-rich book explains seismic data acquisition operations from a fundamental and practical standpoint, ranging from land to marine 2D methods to 3D seismic methods. Helpful to geologists, field crews, exploration managers, petroleum engineers, and geophysicists, each chapter concludes with exercises on field data recording problems.

Details the properties of 3D acquisition geometries and shows how they naturally lead to the 3D symmetric sampling approach to 3D survey design. Many examples are used to illustrate choices of acquisition parameters, and the link between survey parameters and noise suppression as well as imaging is an intrinsic part of the contents.

Written for practicing geophysicists, “Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging” is a comprehensive guide to understanding and interpreting seismic data. The culmination of land seismic data acquisition and processing projects conducted by the author over the last two decades, this book contains more than nearly 800 figures from worldwide case studies—conducted in both 2D and 3D. Beginning with Chapter 1 on seismic characterization of the near-surface, Chapter 2 presents near-surface modeling by traveltime and full-wave inversion, Chapter 3 presents near-surface modeling by imaging, and then Chapter 4 includes detailed case studies for near-surface modeling. Chapter 5 reviews single- and multichannel signal processing of land seismic data with the key objective of removing surface waves and guided waves that are characterized as coherent linear noise. Uncommon seismic data acquisition methods, including large-offset acquisition in thrust belts to capture the large-amplitude supercritical reflections, swath-line acquisition, and joint PP and SH- SH seismic imaging are highlighted in Chapter 6, and Chapter 7 presents image-based rms velocity estimation and discusses the problem of velocity uncertainty. The final two chapters focus exclusively on case studies: 2D in Chapter 8 and 3D in Chapter 9. An outstanding teaching tool, this book includes analysis workflows containing processing steps designed to solve specific problems. Essential for anyone involved in acquisition, processing, and inversion of seismic data, this volume will become the definitive reference for understanding how the variables in seismic acquisition are directly reflected in the data.

This modern introduction to seismic data processing in both exploration and global geophysics demonstrates practical applications through real data and tutorial examples. The underlying physics and mathematics of the various seismic analysis methods are presented, giving students an appreciation of their limitations and potential for creating models of the sub-surface. Designed for a one-semester course, this textbook discusses key techniques within the context of the world's ever increasing need for petroleum and mineral resources - equipping upper undergraduate and graduate students with the tools they need for a career in industry. Examples presented throughout the text allow students to compare different methods and can be demonstrated using the instructor's software of choice. Exercises at the end of sections enable students to check their understanding and put the theory into practice and are complemented by solutions for instructors and additional case study examples online to complete the learning package.

Elements of 3D Seismology, third edition is a thorough introduction to the acquisition, processing, and interpretation of 3D seismic data. This third edition is a major update of the second edition. Sections dealing with interpretation have been greatly revised in accordance with improved understanding and availability of data and software. Practice exercises have been added, as well as a 3D seismic survey predesign exercise. Discussions include: conceptual and historical foundations of modern reflection seismology; an overview of seismic wave phenomena in acoustic, elastic, and porous media; acquisition principles for land and marine seismic surveys; methods used to create 2D and 3D seismic images from field data; concepts of dip moveout, prestack migration, and depth migration; concepts and limitations of 3D seismic interpretation for structure, stratigraphy, and rock property estimation; and the interpretation role of attributes, impedance estimation, and AVO. This book is intended as a general text on reflection seismology, including wave propagation, data acquisition, processing, and interpretation and will be of interest to entry-level geophysicists, experts in related fields (geology, petroleum engineering), and experienced geophysicists in one subfield wishing to learn about another (e.g., interpreters wanting to learn about seismic waves or data acquisition).
