A smooth minimum-structure and artefact-free 1D starting model isĭetermined automatically directly from the seismic traveltime data by Increases the numerical robustness of the inversion. Refraction, transmission and diffraction (Lecomte, 2000) andīack-project traveltime residuals along wave paths also known asįresnel volumes (Watanabe, 1999) instead of conventional rays. Realistic modeling of first break propagation for P-wave and S-wave surveys. Our Smooth inversion tomographic method is based on physically Velocity variation and other velocity anomalies. Our Rayfract® refraction tomography software allows reliable imaging of subsurface velocity structure including ![]()
