Welcome to the SEG Wiki. 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. Start contributing today - every edit makes a difference. Personalized support is always available.

Key concepts from SEG Books

This is a new project underway to create articles that summarize key concepts in SEG books. SEG Wiki staff are currently working with author Donald A. Herron on entries that will serve as an introduction to this project. Don's entries on Interpretation work flows, Visual estimation of wavelet phase, and Correlation procedures in building a depth migration velocity model are now available! If you are interested in assisting with this project, please contact wiki‐at‐seg.org.
