These packages offer some subset of functionality of the full processing packages in the previous section. Reads most common SEGY and a subset of SEGD formats. World's most widely used (82 countries and territories).ījorn Olofsson, now property of the Colorado School of Mines Generic format (SEGY, SU, SEPlib, USP, Madagascar) Includes OBS Node Survey Simulator, BP Anisotropic Velocity-Analysis Benchmark Programming Interfaces to Fortran 77, Fortran 90, Python, Java, MATLAB, Julia. Multidimensional data analysis including seismic processing They are relatively low-level and in some cases have their own data formats and involve learning an extensive syntax or meta-language. These are full-featured reflection seismology processing packages, with support for modeling, imaging, and inversion. 6 Not true free and open-source projects.5 Visualization, interpretation, analysis packages.3 Nonreflection seismic processing utilities.2 Reflection seismic processing utilities.1 Reflection seismic processing packages.
