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.

Wiki help video series

This help series aims to provide you with the skills necessary to start contributing. We have completed help videos on launching your own user page, growing articles in our biographies section, and advanced tutorials on improving Sheriff's Dictionary. Future videos are planned, so bookmark the playlist!

TLE tutorials

The SEG is publishing an increasing number of geophysical tutorials. The seventh tutorial, Picking unconformities, was recently published in the February 2015 edition of The Leading Edge.

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!

Oz Yilmaz’s renowned Seismic Data Analysis is now fully available as an open access book and freely available to read, edit, and grow through your contributions!


Many of the pioneers in the development of exploration geophysics reside in the Biographies. Add your insight and knowledge of these trailblazers for the next generation.

Please help us develop our women in geoscience biographies.
