SF IMAGER is mainly used to process optimum offset seismic reflection data. It provides filtering, random noise attenuation, and deconvolution to improve the S/N ratio. You can import or pick velocities, migrate the time section, and generate a depth profile. SF IMAGER is also used to process the g ...

DW TOMO 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 ch ...

REFRACTOR provides the intercept time method, delay time method, ABC method, and generalized reciprocal method (GRM) for seismic refraction surveys. You can automatically or manually pick first breaks, easily assign first arrivals to layers, and quickly phantom time-distance curves. The velocity and ...

VSP can handle the zero-offset and offset VSP surveys. It uses the F-K or median filter to separate upgoing and downgoing waves, and then deconvolves the upgoing waves by applying a wavelet designed on the downgoing waves. Finally, it builds a corridor stack, or VSP-CDP mapping Features Support ...
