Welcome to the SEG Wiki
About the SEG Wiki
The goal of the SEG Wiki is to: expand the world’s knowledge of geophysics, further layer the science, and engage emerging professionals in the field. Robert E. Sheriff's Encyclopedic Dictionary of Applied Geophysics, fourth edition and Oz Yilmaz's Seismic Data Analysis seeded the SEG Wiki with its initial content. We encourage you to read, edit, and enhance the SEG Wiki. Add your layer to the science of geophysics today.

Key concepts from SEG books
SEG Wiki has been working closely with Don Herron to create wiki articles based on Don’s 2011 book First Steps in Seismic Interpretation. Don has condensed, expanded, and paraphrased key concepts from his book for the wiki. Articles on derivation of Poisson's ratio, derivation of reflection coefficient, derivation of Snell's Law, correlation procedures in building a depth migration velocity model, interpretation work flows, and visual estimation of wavelet phase are now available.
Seismic Data Analysis is here!
Please help us develop our women in geoscience biographies.
