High-quality imaging capabilities
DAS has a broadband response with a noise floor similar to, or exceeding, geophones. Combined with dense spatial sampling the allows high-quality seismic imaging of the subsurface.
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 and is suitable for surveys in both soft and hard rock.
With one cable DAS measurements can be combined with temperature (DTS) and strain (DSS) measurements to facilitate enhanced interpretation of geological structures, and hence improve exploration efficiency.
