Öz Yilmaz has expanded his original work on processing to include inversion and interpretation of seismic data. In addition to the developments in all aspects of conventional processing, this content represents a comprehensive and complete coverage of the modern trends in the seismic industry-from time to depth, from 3-D to 4-D, from 4-D to 4-C, and from isotropy to anisotropy.
As technology evolves and advances, help us keep this valuable contribution to geophysics up-to-date by making your own contributions that reflect the latest science of seismic data analysis and applied geophysics.
"A geophysicist, who practices seismic data processing, inversion, and interpretation, would want to have a quick reference under his/her fingertips for the theory and practice of all processing methods and algorithms, for determining an optimum processing sequence with optimum parameters for each step --- whether it is for AVO inversion or for earth imaging in time and depth. Now, via SEG Wiki, you can access Seismic Data Analysis to obtain the information you need." - Oz Yilmaz, August 2014
