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

SURFACE is able to process active surface waves with SASW and MASW. The dispersion spectrum can be calculated in F-K, F-V, or F-P domain, where the fundamental and high-mode dispersion curves are interactively picked. The robust forward modeling and the global genetic algorithm (GA) assure the quick ...

XW TOMO
The velocity between wells can be estimated with travel time. Based on the grid ray tracing and regularized inversion approach, XW TOMO is capable of deriving the velocity structure among multiple vertical or deviated wells, while also allowing ground-surface variation.

PS LOG is designed to efficiently process data in well velocity surveys. After the depth of receivers and the direction of a shot are defined, first breaks can be picked with the mouse button on P and S waves simultaneously in the analysis window. Meanwhile, the interval velocity, average velocity, ...
