smartRefract – software for seismic refraction processing

smartRefract is an open source seismic refraction software that implements the GRM method (Palmer 1980). The software allows you to select the first arrivals, assign the dromochrones to the layers and draw the section.
The software is complete but it is to be considered a working prototype. It is compatible with SEG2, SU and some SEGY formats.

Download

The executables for Windows and Linux are located under the bin folder.

Requirements

SmartRefract requires installation of JavaSE JDK version 11 or later. It can be downloaded for personal use from https://www.oracle.com/technetwork/java/javase/downloads/jdk13-downloads-5672538.html or for any use from https://jdk.java.net/13/.

Il requires Netbeans IDE to be run.

smartTomo

SmartTomo is an efficient software for processing seismic refraction tomography (SRT).  It includes an advanced tool to display and customize the results. The output is the product of the iterative optimization of the starting model. Additionally, the user can define the initial model to fit the knowledge of the geology of the survey area.
SmartTomo uses an optimized implementation of the method by Moser, T. J. (” Shortest path calculation of seismic rays.” Geophysics 56.1 (1991): 59-67)) and optimizes the results through a specialized Simultaneous Iterative Reconstruction Technique. To guarantee efficiency, it exploits the computational power of modern multicore CPUs, while minimizing the required amount of memory.

Key points

  • Both manual and automatic first brake picking. Possibility to pick first breaks automatically or by hand.
  • The computation of tomographic at leasts needs the check by the user of automatics pickings. The computation of the tomographic profile can be almost completely automated. The user can supervise the computation and possibly provide specialized settings.
  • More seismic arrays can be combined to compose an unique seismic profile.
  • The initial model of velocity can be user-defined.
  • The initial model does not influence the result significantly.
  • The project size is limited only by available memory.
  • Users can set limit to the velocity range and smooth the result.
  • The result can be plotted using predefined or user-defined color palettes.
  • Both plot and data tables can be exported in different formats (PNG, PDF, ODT);
  • The tomographic profile can be exported in XZ-Velocity file compatible with Golden Software Surfer
