A Practical Understanding of Pre/Poststack Vol.1 (Poststack)

by John C. Bancroft

A Practical Understanding of Pre- and Poststack Migrations, Volume 1 (Poststack), 2007 edition John C. Bancroft 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. Also Covariance Analysis for Seismic Signal Processing - ISBN 156080081X
