DW Tomo — Refraction Tomography Estimate velocity model from first arrivals with ray-tracing scheme and iterative inversion
Refraction Tomography does not require layer assignment and phantom time-distance curves. The complex velocity structure can be directly estimated from first arrivals. This approach is especially suitable to derive the structure with no distinct layer interface due to the gradual velocity change where the traditional refraction interpretation methods are invalid.
DW TOMO utilizes the robust grid ray tracing and regularized inversion with constraints in tomography. The estimated velocity model can also be used for static correction in seismic reflection data processing.
