This paper explains scripts that process a small 3D land seismic survey with the open software system, Madagascar. The processing sequence 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. The scripts mostly use the “trace and header” (or “tah”) programs recently added to Madagascar that are useful to handle data that is not regularly sampled.

The workflow is divided into stages that correspond to a typical processing sequence. A computer processing stage produces printed information and displays that are required to create the processing scripts for the next processing stage. The seismic processor selects which data to process, parameters to use. The displays are also used to verify data is correctly processed before moving to the next stage.

The paper assumes the reader has installed the Madagascar software. The reader may recreate the processing or build on this paper by selecting your own parameters, using different programs, updating programs, or writing new programs. The scripts can also be used as a template to process other 3D surveys.
