Silixa Carina Sensing System

The Carina system redefines the standards of DAS technology, delivering parameters unavailable to competing solutions. Choosing this system means above all:

• Unmatched sensitivity: The system offers 100 times higher sensitivity (20 dB lower noise level) than standard DAS systems, thanks to the patented Constellation™ fiber.

• Range without compromise: Precise monitoring over distances up to 100 km while maintaining a crystal-clear signal.

• Detection of “inaudible” signals: An extremely low detection threshold makes it possible to capture events that other systems dismiss as background noise (e.g. micro-leaks or micro-seismicity).

• Cost reduction: A single system replaces thousands of traditional point sensors (geophones), eliminating the need to build costly field power infrastructure.

• Versatility: Ideal for operation in extreme conditions – from deep boreholes to glacier monitoring.

Technical characteristics:

• Constellation™ technology: Uses specially engineered reflection points in the fiber to maximize the signal-to-noise ratio (SNR).

• Highest spatial resolution: A dense grid of measurement points (every few meters) along the entire cable length.

• Wide dynamic range: The ability to precisely record both subtle vibrations and powerful seismic shocks without the risk of clipping.

Main applications:

• Mining: Microseismic monitoring, stability control of extraction walls and tailings dams.

• Oil & Gas and CCS: Borehole seismic (VSP), fracturing monitoring and control of underground CO2 storage.

• Infrastructure protection: Advanced perimeter security of borders and strategic facilities.

• Environmental research: Monitoring of glacier activity, oceanography and seismology.
