SEG/EAGE Salt and Overthrust Models

The SEG/EAGE Salt and Overthrust models were created as part of a joint project between the Society of Exploration Geophysicists and the European Association of Geoscientists and Engineers. The datasets were originally released by the SEG as a part of the SEG/EAGE 3-D Modeling Series and are redistributed with the consent of the authors and the corresponding institutions.


The SEG/EAGE Salt and Overthrust models are two 3-D geological models that were created as part of a multi-phase collaboration between the SEG and EAGE, with funding from the U.S. Department of Energy National Laboratories, as well as several institutions from industry and academia. The models were developed by an SEG/EAGE 3-D Modeling committee, which was co-chaired by by Fred Aminzadeh (University of Southern California) and Fabio Rocca (Politecinio di Milano).

The two datasets consist of the 3-D subsurface velocity models, as well as model surfaces and supplementary documentation. Refer to the appendix of the accompanying CD booklet for a full description of the content.

Synthetic seismic traces are available for the Salt model. See the pages SEG/EAGE_3D_modeling_Salt_Model_Phase-C_1996

There are no generally available seismic traces for the Overthrust model.

How to Download

The SEG/EAGE Salt and Overthrust Model data collected in a tar/compressed file. It can be downloaded by clicking the link or pasting the command:

into a Linux/Mac OSX command line terminal.

After the file is downloaded it can be expanded in a terminal with the command:

tar -xvf salt_and_overthrust_models.tar.gz

After running the tar command the booklet describing the models is the file:

or online at:

CD booklet

salt_and_overthrust_models.tar.gz contains the all the data originally distributed on 3 CD's and a supplementary directory that contains the CD booklet (SEG-EAGE_3-D_salt_overthrust_models.pdf).

You can download the CD's separately by clicking the links or pasting the commands:


After the files are downloaded they can be expanded in a terminal with the commands:

tar -xvf Overthrust_3D_CD1.tar.gz
tar -xvf Overthrust_3D_CD2.tar.gz
tar -xvf Salt_Model_3D.tar.gz

The data is the same, but you can download only part of the data with these three files. The pdf describing the data is replicated on each of these three files.

This model was created by the SEG/EAGE 3-D Modeling committee, co-chaired by Fred Aminzadeh (University of Southern California) and Fabio Rocca (Politecinio di Milano). Chairpersons of the working groups included Kay Wyatt (Phillips Petroleum), Patrick Lailly (IFP), Norm Burkhard (Lawrence Livermore National Laboratory), Tim Kunz (Amoco), Jun Hua Chen (Chevron) and Max Mulder (TNO).

Researchers involved in the creation of this model further include Jean Brac, Pierre Duclos, Laurence Nicoletis, Jean-Claude Lecomte and Alain Bamberger (all IFP), as well as Jane Long (Lawrence Livermore National Laboratory).

This model was added to the SEG Open Data collection with help from Joseph Dellinger (BP), Ted Bakamjian (SEG), Dieter Werthmüller (TU Delft) and Philipp Witte (Georgia Institute of Technology).
