The downhole seismic method (DH) measures the time the P and S waves can move between a seismic source located on the ground’s surface and the receivers placed inside a borehole.



Software for processing seismic tests using the DownHole method.

Once entered the information for the project, the depth reached, and the travel times, we can get:

    • the distances from the source to the receiver;
    • corrected travel times;
    • speeds of P and S waves;
    • some important geotechnical parameters;
    • the travel time graph with seismic layers from which can be determined the average velocity in each layer, some average geotechnical parameters and VS30;
    • the graph of P and S waves interval velocity and definition of seismic layer;
    • graphics relating to geotechnical parameters, derived for each interval;
    • the stratigraphy of the borehole;
    • the final report.

The import of SEG2 files ensures this software’s high compatibility with the working tools.


With the direct method, initially, the travel times (t) measured along the source-receiver paths must be corrected to take into account the inclination of the path of the waves and then realize the chart tcor-z, for both P waves and S waves.

Thus, the average speed of seismic waves in homogeneous soil layers is represented by the inclination of the line segments aligned to the experimental data.

Once the seismic layers are graphically obtained, we get the average density, from the speed and depth, Poisson’s ratio, shear deformation modulus, oedometric modulus, Young’s modulus, bulk modulus, VS30.


In the interval method, travel times are measured between two receivers placed at different depths, thus allowing for better-quality measurements (speed intervals).

When we have only one receiver, assuming that the pairs do not match a single impulse, the rate-determined values are defined in the pseudo-range, allowing only an apparent better definition of the velocity profile.

Once we have the measurements is possible to calculate the corrected travel times and interval velocity for the P and S waves, along with the related graphic.

Then we can calculate the density, Poisson’s ratio, the shear deformation modulus, the oedometric modulus, Young’s modulus, the bulk modulus for each interval and VS30.

Overall update



  • Added the possibility to shift the traces by decoupling the P waves, the S1 waves and the S2 waves. 
  • Implemented the computation of mean parameters using the interval method when the software does not automatically determine the soil unit weight. 
  • Import of *.seg2 files generated following the standard of numerical data on16 bits. 
  • Implemented the possibility of copying the seismic stratigraphy defined with the Direct Method into the Interval Method. 
  • Import of *.drm files. 
  • Implemented the graphic of the velocity profile for P and S waves in the "direct" and "interval" methods regarding the imposed seismic stratigraphy. 
  • Introduced the possibility of eliminating the offset from the seismic traces (continuous component). 
  • Improved handling of graphics with the ability to intervene on the height of the texts for the title of illustrations, numerical values ?? and descriptions of the axes. 
  • Improved management of the grid for graphics. 
  • Introduced the ability to display the picking values processed on the seismograms. 
  • Added the ability to process only the S waves. 
  • Implemented the ability to analyze files from acquisitions with a double geophone. 
  • Added the ability to normalize the traces in the analysis phase. 
  • Added the ability to filter the tracks. 
  • A modification has been performed on the calculation of Vs30. If the test does not reach 30 meters, the last layer is extended to 30 meters. 
  • Complete review of the software in national and international versions. 
  • Import traces are generated using the Ambrogeo tools (*. dta files). 
  • Released English and Spanish versions. 
  • Edit extraction and design of the tracks from SEG2 files.

    Indeed a nice tool for specific Downhole Test, support team did a terrific job helping me to enable an on screen option to be able to choose my channel for my vertical component so… great job and thanks a lot!

    I´ll be waiting for this tool to add more specifics, like inclination for example…?
