Seismic Data Processing with Seismic Unix

In 2005, Thomas Benz, Professor Wayne D. Pennington, and I published a book designed to teach some of the basics of seismic data processing. The book, "Seismic Data Processing with Seismic Un*x" was published by the Society of Exploration Geophysicists.

Seismic Unix is a command line tool; that is, there is no graphical user interface (GUI) for it, although over time, people have tried to create a GUI, but a GUI never became popular.

I recommend the book because I think it has a lot of good parts. Please note, none of the authors receive royalties (money) from book sales. A link to the book on the SEG web site is below.

The book begins by explaining Unix commands, then moves on to create synthetic datasets and processes them. That takes up a little over half the book. The rest of the book (leaving out the several appendixes) continues teaching by using three real seismic datasets.

The Nankai datasets are two files of real seismic data, both provided by Prof. Greg Moore of the University of Hawaii. The data were collected near the coast of Japan, over the Nankai trough, where the Philippines plate is subducting beneath Eurasia. The Nankai data were collected by the University of Texas, the University of Tulsa, and the University of Tokyo. Based on this data set, a paper was published (reference below) in which this line is called NT62-8.

The Taiwan dataset is a real 2-D line of shot gathers, also provided by Prof. Greg Moore of the University of Hawaii. This Taiwan dataset was collected near the coast of Taiwan in 1995 (reference below) by the University of Hawaii, San Jose State University, and National Taiwan University.

I created the table below to make the three datasets available in Seismic Unix (.su) format and SEG-Y (.sgy) format. Click an appropriate cell to download a file. Please note, I created the SEG-Y files from the .su files — I do not have the original SEG-Y files.
