Geogiga PS Log 9.1 — Well Velocity Survey Software

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, and Poisson's ratio are automatically updated.

Features

Quickly define the geometry with layout chart

Butterworth and Ormsby filters with band pass, low pass, high pass, band reject, and notch options
