Borehole Geophone for P- and S-Waves, Triaxial Borehole Geophone Seismic Borehole Receivers
The borehole geophone is used to receive P- and S-waves in dry or water filled boreholes. The borehole geophone consists of a tri-axial sensor whereas the consists of six horizontal sensors, separated by 30° intervals, and one vertical sensor.
The borehole geophone is pneumatically clamped to the borehole wall by means of a robust air bladder, or electromagnetic switch clamped to the borehole. A magnetic compass shows azimuthal deviation to North. Typical applications are VSP surveys, crosshole measurements and shear wave tomography.
