An essential ingredient for successful 3-D seismic survey design is a basic understanding of the spatial properties of the seismic wavefield. These properties were described for 2-D seismic data in Seismic Wavefield Sampling by the same author. This book extends the description into the much more complex field of 3-D seismic data. A chapter on guidelines for survey design translates theory into practice. Some case histories illustrate the concepts. Noise suppression, resolution, and imaging are discussed in detail. Converted-wave survey design is covered in a separate chapter. This book provides essential knowledge for any acquisition or processing geophysicist and is recommended to everyone dealing with 3-D seismic data. An included CD-ROM also contains an Acquisition Design Wizard and survey optimization software.
