CGG announced that Sercel has launched GeoTag, the 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 down to 500 meters, the company said.

GeoTag solution operates with the smallest acoustic positioning transponder available on the market. The transponders are attached to the seabed seismic equipment and interrogated by a vessel-based transceiver. The transponders can also be stored on a reel and deployed mechanically when used with OBC systems.

GeoTag is fully scalable for use on small to large seabed crews deploying up to 10,000 acoustic positioning devices, the company wrote in a press release.

Pascal Rouiller, Sercel CEO, said: “This new product capitalizes on our proven experience in acoustic positioning. It answers the need in the industry for more accurate positioning of seabed seismic equipment, particularly for 4D operations.”
