Rayfract™ Seismic Refraction Tomography software allows imaging of subsurface velocity structure based on seismic first break energy propagation modeling.

An initial 1D gradient model is determined automatically directly from the traveltime data, with the Delta-t-V method (improved Herglotz-Wiechert method). This initial model is then refined with true 2D WET Wavepath Eikonal Traveltime tomography processing. Also, the software allows interpretation of traveltimes with conventional Plus-Minus and Wavefront seismic refraction methods.
