Rayfract® Featured

The Rayfract® Seismic Refraction Tomography software allows reliable imaging of subsurface velocity structure. Our tomographic data interpretation is based on physically meaningful modeling of wave propagation with wave paths instead of conventional seismic rays. This increases the numerical robustness of the inversion, especially in low coverage situations.

An initial 1D gradient model is determined automatically directly from the traveltime data, with the Delta-t-V method (improved Herglotz-Wiechert method). This method delivers reliable models even in case of velocity inversions. The 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. Also allows borehole receiver spread tomography. Add borehole receiver line to main refraction line for joint inversion.
