Processing the Teapot Dome Land 3D Survey with Madagascar

Conclusions

This paper describes basic processing of the Open 3D seismic survey Teapot Dome using the open software package Madagascar. The scripts are distributed with the Madagascar software and the results in this paper can be reproduced on a Linux or Mac laptop computer.

This processing framework has four intended uses:

1. A 3D land seismic processing tutorial
2. A Madagascar tutorial
3. Prepare 3D data to test and validate new seismic algorithms or programs
4. Encourage others to write new programs, improve existing programs, and select better parameters to improve on the results show in this paper.

The processing applied in the scripts includes data loading, geometry plotting, spreading correction, surface consistent decon, scaling, refraction statics application, stacking velocity analysis, and post stack migration. The processing scripts also illustrate how seismic processors display and select processing parameters.

There are some missing processing stages, notably velocity estimation (interactive velocity picking, automatic velocity picking, tomographic velocity inversion, FWI), statics estimation (refraction statics, residual statics), noise attenuation, and prestack migration (Kirchhoff time or depth migration, shot migration, reverse time migration). Results from some processing stages should be improved, notable the post stack migration.
