- Telemetry system
- ADC 32 bits
- High-quality anchoring arm
- Anchoring arm stops automatically when force rating is reached
Detailed Description
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.
Common receiver gather, acquired by SHock borehole seismic source and TELSS-VSP 3C seismic probe, located in the nearby well.
Two gathers are shown on the top, P and S waves spectra are shown on the bottom. Source operation was provided by Jack energy source
