Geogiga PS Log 7.3 - Well Velocity Survey Software

PS LOG is designed to efficiently process the data in the well velocity survey. After defining the depth of receivers and the direction of shot, you can pick first breaks 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.



  • Quickly define the geometry with layout chart
  • Butterworth and Ormsby filters with band pass, low pass, high pass, band reject and notch options
  • Automatic gain control (AGC), trace balance, time variant scaling and single trace scaling
  • Undo and redo multi-step processing on seismic data
  • Simultaneously display P and S wave at all depths
  • Interactively pick the first breaks of P and S waves with a trace magnifier
  • Automatically calculate interval velocity, average velocity and Poisson's ratio
  • Manually assign layers based on regression lines
  • Calculate the Elastic Modulus including Shear Modulus, Young's Modulus and Bulk Modulus
  • Output results in a table
