TELSS-VSP telemetry borehole seismic acquisition system is designed for VSP, polarization VSP, uphole and crosshole surveying.
The mobility of the system allows the use of it in boreholes as deep as 100 meters (and even more).
The presence of 3-component sensor and anchoring arm allows to register full wavefield, including primary, secondary and other waves.
