Cost-saving high-quality data
Carina® Sensing System
, the precision engineered distributed acoustic sensing system, has a broadband response with a noise floor similar to geophones. This facilitates the correct recording of seismic events over a wide range of magnitudes. The sensing element is the fibre which can be kilometres long and spatial sampling can be <1m. This enables good coverage of large operational areas with one measurement and makes the technology cost-efficient.
Improved interpretation of data through dense measurements leads to an enhanced understanding of the situation, enabling action to be taken when necessary. With one cable DAS measurements can be combined with temperature (DTS) and strain (DSS) measurements to provide further insight. Unmanned and remote operations, with minimum maintenance, improve site safety.
Flexible deployment of the system enables increased operational efficiency. Fibre-optic cables can be temporarily or permanently deployed, remaining operational for years. They may be buried at the surface or installed in boreholes. The technology can be used in harsh and high-temperature environments with no maintenance requirements to the cable.
