Seismic surveys are subject to many different design criteria, but often the parameters are established based on an outdated view of how data can be acquired and how it will be processed.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.

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.

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.

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.

The effectiveness of seismic imaging depends on numerous factors, beginning with how the data are acquired. The analyses presented in this theses show the importance of survey design, as individual parameters exert a strong influence over the resulting subsurface illumination. Survey design studies discussed here with different geological settings and geographical locations include: 1) Marine surveys with circular shooting for a subsalt target in the Gulf of Mexico, 2) Multicomponent land seismic survey designs for an unconventional resource, and 3) Integrated geophysical data analyses and survey design for a blind fault imaging at the 2010 Haiti earthquake epicentral area. In the case of marine surveys, the dual-coil design provides full-azimuthal coverage, whereas the Wide-azimuth surveys (WAZ) contain some acquisition footprints due to their straight-line geometry with limited-azimuthal coverage. Survey design optimization quantified the WAZ survey as having 20 % less illumination intensity than the dual-coil survey. For the multicomponent survey design, we analyzed the effects of VP/VS values (2, 4, and 6), target depth (800, 1,600, and 3,200 m) and orthogonal or slanted shot geometries. The updip shifting of the illumination area due to target layer inclination (5 ̊, 15 ̊, and 30 ̊) required longer offsets to fully capture the seismic data. Staggered (periodically shifted) receiver lines achieved smaller bin sizes (6.25 m vs 25 m) with a very little additional acquisition effort. We also consider a case history from Léogâne fan-delta in Haiti, where some of the worst shaking was located by the 2010 Haiti earthquake. This intense shaking of the fan-delta area was attributed to either activation of a blind thrust fault, ~4 km beneath the surface, or to a strike-slip motion along a shallow, ground-breaking fault. We acquired seismic, gravity, and GPS data which were integrated with remote sensing studies. Our integrated results indicated disruptions of the near-surface material in the Léogâne region. Survey design studies suggested that multiple 2D seismic lines with 6 km offsets and optional marine surveys may be required to image the proposed blind fault. This thesis suggests novel seismic survey designs for a variety of subsurface geologies.
