Welcome to Drisana Geotechnical Consultancy!
A tri-axial geophone is moved down into a borehole connected with a seismograph regularly, the geophones are jammed into the hole. On the ground surface, P and S wave are generated usually with a sledge hammer hitting a beam. P waves are done hitting vertically an aluminium plate on the ground. To create S waves, we can strike a piece of wood firmly blocked (below cars tire for example).
This software is designed to process downhole seismic using a tri axis geophone clamped into the hole and energy source at the surface. P-Wave and S-Wave are generated and recorded in order to compute the Elastic properties.
For analysis the field data using Win_downhole following step require
From downhole test we calculate the following Dynamic properties.
