MATLAB-Based Seismic Processing Software

The GeoPhysics Department at the University of Alberta has developed a comprehensive MATLAB-based seismic processing software that features an intuitive graphical user interface (GUI) and robust algorithmic implementations. The software architecture utilizes MATLAB's Signal Processing Toolbox for implementing advanced filtering techniques, including bandpass filters and FK filters for noise attenuation. Key modules include seismic data preprocessing with automated quality control checks, velocity analysis through semblance algorithms, and migration processing using both Kirchhoff and reverse-time migration methods. The software implements seismic data processing workflows through object-oriented programming, where seismic traces are handled as matrix objects enabling efficient vectorized operations. Core functions include data input/output handlers supporting SEG-Y format parsing, wavelet processing routines for deconvolution, and interactive velocity picking tools with semblance coefficient calculations. The system employs MATLAB's parallel computing capabilities for large dataset processing, particularly useful for 3D seismic volume operations and stack velocity analysis. For imaging and interpretation, the software incorporates depth migration algorithms with finite-difference wave propagation modeling and provides API interfaces for custom script development. The modular design allows researchers to implement proprietary algorithms while maintaining compatibility with standard processing flows. Regular updates incorporate latest research developments, including machine learning approaches for automated first-break picking and deep learning-based noise classification modules. The software supports both land and marine seismic data processing, with specialized routines for handling topography corrections and water column velocity variations. Its applications span hydrocarbon exploration, earthquake seismology, and academic research, providing complete solutions from raw data acquisition to final interpretation products through customizable processing chains and quality control visualization tools.
