Abstract This is a new edition of Ilya Tsvankin’s reference volume on seismic anisotropy and application of anisotropic models in reflection seismology. Seismic Signatures and Analysis of Reflection Data in Anisotropic Media, Geophysical References Series No. 19, provides essential background information about anisotropic wave propagation, introduces efficient notation for transversely isotropic (TI) and orthorhombic media, and identifies the key anisotropy parameters for imaging and amplitude analysis. To gain insight into the influence of anisotropy on a wide range of seismic signatures, exact solutions are simplified in the weak-anisotropy approximation.

Abstract Concepts and Applications in 3D Seismic Imaging (SEG Distinguished Instructor Series No. 10) provides a broad and intuitive understanding of seismic-imaging concepts and methods that enables geoscientists to make appropriate decisions during acquisition, processing, imaging, and interpretation. This book, first published for use with the SEG/EAGE 2007 Distinguished Instructor Short Course, also exposes participants to current trends in imaging research and empowers them to adopt new technologies quickly. Seismic images are the basis of critical exploration, development, and production decisions. Optimal use of these images requires full understanding of the processes that create them, from data acquisition to final migration. (DISC on DVD, 756A, is also available.)

Abstract This volume, SEG Course Notes Series No. 13, is designed to give the practicing geophysicist an understanding of the principles of poststack migration, presented with intuitive reasoning rather than laborious math. Modeling is introduced as a natural process that starts with a geologic model and then builds seismic data. Migration is then described as the reverse process that uses seismic data to find the geologic model. Many other topics are covered relating to the quality of the migrated section, such as aliasing, rugged topography, or use of the correct velocity. Significant new material has been added in this revised edition of the original 1997 book, especially algorithms based on the phase-shift method, such as PSPI and the omegaX method.

Abstract This volume, SEG Course Notes Series No. 14, is designed to give the practicing geophysicist an understanding of the principles of prestack migration, presented with intuitive reasoning that avoids difficult math. Modeling with common-shot record and a constant-offset section are used to introduce prestack migration. New material in this revised edition of the original 1998 book includes algorithms that lead to and include Claerbout’s inversion method.
