Seismic Data Analysis

Oz Yilmaz’s renowned text now available

It is here! Oz Yilmaz’s renowned Seismic Data Analysis is now fully available as an open access book. With its launch, SEG’s two best-selling books – Seismic Data Analysis and Sheriff’s Encyclopedia Dictionary of Applied Geophysics – are freely available to read, edit, and grow through your contributions! According to Yilmaz:

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.


Wiki chat

Our second #SEGWikiChat will occur Tuesday, October 21, with special guest Online Committee chair Matt Hall. The 2nd annual SEG Wikithon will be the theme of that chat. Join us!

  • Date and time: Tuesday, 21 October 2014, 10:00-11:00am CST
  • Place: SEG Wiki channel on Muut
  • Audience: All SEG members, and the greater geophysics community

All questions are welcome. Cannot make the chat? Email your questions to wiki@seg.org.

Wikithon 2014

The 2nd Annual SEG Wikithon will be held October 26-29 in Denver, CO during the SEG International Exposition and 84th Annual Meeting. Please help us design sessions that meet your needs. New to the SEG Wiki? An experienced wiki editor or geophysicist? Connect with other wiki contributors at the 2014 Wikithon during the SEG Annual Meeting.

Location: Room Deck 708, Colorado Convention Center
Time: 12 – 2pm AND 5 – 6pm October 26-29

We will also host two student-focused sessions at the Student Pavilion on Monday, October 27 from 3-4pm and on Tuesday, October 28 from 12-2pm.

New additions

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. Entries on interpretation work flows, visual estimation of wavelet phase, and correlation procedures in building a depth migration velocity model are now available.

The SEG Wiki team aims to partner with other authors and subject matter experts to prepare entries on additional key concepts from SEG books. If you are interested in assisting with this project, please contact wiki@seg.org.

TLE tutorials

The SEG is publishing an increasing number of geophysical tutorials. The fifth tutorial, Phase and the Hilbert transform, was recently published in the October 2014 edition of The Leading Edge.

Biographies and Awards


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.

About the SEG Wiki

The goal of the SEG Wiki is: expanding the world’s knowledge of geophysics, creating a stronger science, and engaging emerging professionals in the field

Robert E. Sheriff's Encyclopedic Dictionary of Applied Geophysics, fourth edition seeded the SEG Wiki with its initial content. While this information originated in a tried and true print source, all entries in the SEG Wiki can and are encouraged to be modified, updated, and improved by members.

We encourage you to read and enhance the SEG Wiki to the best of your knowledge. Personalized support is always available. Add your layer to the science of geophysics today.
