- Seismic Reflection Processing Software


Visual_SUNT is a Windows 32 or 64 bits software that is linked to SUNT modules (Seismic UNIX for Windows).

SUNT is an adaptation for Windows of SEISMIC UNIX  (Center for Wave Phenomena of Colorado School of Mine). There are more than 100 modules allowing all usual steps of seismic reflection processing. There is no limit on the number of traces!

Visual_SUNT also contains specific utility modules that complement those of SUNT. With Visual_SUNT you can easily convert SEG-2, SEG-Y, SEG-D, ABEM and OYO data to SU/SEGY. Among the Visual_SUNT utility modules are: Header display, Header edit, frequency spectrum, on screen mute and trace kill, geometry display, velocity computation with hyperbola curve, first breaks pick, easy geometry input, FK filtering, deconvolution, velocity semblance, residual statics, stacking chart  and more...

Visual_SUNT batch editor is a powerful tool with on line help and interactive input. All important SU/SUNT modules have an input panel with comments and default values.

Visual_SUNT display options are multiple: wiggle, amplitude, color, gray scale... You can print at any scale your printer is capable of, and very long plots are possible. You can also save profiles on files (BMP or JPG).

  • Modelization software
