Sercel launches GeoTag acoustic positioning system

Offshore staff

PARISSercel has launched GeoTag, its acoustic positioning solution for seabed seismic acquisition. GeoTag can be used to accurately position all types of ocean bottom cable (OBC), ocean bottom node and transition zone cable systems for seabed seismic surveys in water depths to 500 m (1,640 ft), said Sercel.

GeoTag operates with the smallest acoustic positioning transponder available on the market, said Sercel. The transponders are attached to the seabed seismic equipment and interrogated by a vessel-based transceiver.

GeoTag’s design allows for rapid maintenance such as battery replacement. The transponders can also be stored on a reel and deployed mechanically when used with OBC systems, for seamless and cost-effective operations.

Sercel said GeoTag is fully scalable for use on small to large seabed crews deploying up to 10,000 acoustic positioning devices.
