Now supports crosshole surveys and walkaway VSP surveys. Borehole Tomography software : velocity structure imaging for engineering and exploration. As part of a geotechnical assessment and feasibility planning of channel improvement a shallow marine seismic refraction survey was. Also allows interpretation of traveltimes with conventional Plus-Minus and Wavefront seismic refraction methods. Supports many input data formats and extreme topography. No need to map traveltimes to refractors. The initial model is then refined with true 2D WET Wavepath Eikonal Traveltime tomography.

This procedure delivers reliable smoothed models even in case of velocity inversions. Seismic Refraction Data interpretation with RAYFRACT Software A short overview.

The seismic data was processed by using computer software such as Ras-24, Rayfract and surfer. A smooth initial 1D gradient model is determined automatically directly from the traveltime data, by averaging DELTA-t-V method 1D velocity-depth Profiles along the seismic line. to the site made accurate data collection more difficult. This increases the numerical robustness of the method. The resulting tomograms were then compared to. Both P-wave and S-wave propagation is modeled with wave paths (also known as Fresnel volumes) instead of conventional seismic rays. programs, specifically Rayfract, SeisImager, and SeisOpt Pro, to image the subsurface were evaluated. Rayfract seismic refraction tomography software (Intelligent Resources, Inc., Vancouver, Canada) and assigned correct shot and geophone.

Our Smooth inversion tomographic method is based on physically meaningful modeling of seismic first break energy refraction, Transmission and diffraction. Rayfract(R) geophysical software for geotechnical engineering and exploration generates subsurface velocity models from seismic first break data. Our Rayfract seismic refraction tomography software allows reliable imaging of subsurface velocity structure including faults, strong lateral velocity. Our Rayfract seismic refraction tomography software allows reliable imaging of subsurface velocity structure including faults, strong lateral velocity variation and other velocity anomalies.
