Rayfract® – Refraction Tomography Software

Rayfract^® is a seismic refraction tomography software that enables reliable imaging of subsurface velocity structures. Its tomographic data interpretation is based on physically meaningful modeling of wave propagation using wave paths, rather than conventional seismic rays, increasing the numerical robustness of the inversion, especially in low coverage situations.

Methodology

• An initial 1D gradient model is automatically determined from refraction traveltime data by laterally averaging 1D velocity-depth profiles obtained with the DeltatV method (improved Herglotz-Wiechert method). This provides reliable starting models even in cases of velocity inversions.

• The initial model is refined using 2D WET (Wavepath Eikonal Traveltime) inversion.

• The software also supports:

  • Also the software allows interpretation of traveltimes with conventional Plus-Minus and Wavefront seismic refraction methods and using these layered refraction starting models for WET inversion

  • Borehole receiver spread tomography. Add borehole receiver line to main refraction line for joint WET inversion.

Supported Operating Systems

• Rayfract^® is a Windows 32-bit application that runs smoothly on Windows 7, 8, 10, and 11 (64-bit systems)

• Each license includes a CodeMeter USB dongle for copy protection

• Golden Software Surfer is required for tomogram display
