Shearwater GeoServices is pleased to announce the award of a large 4D ocean bottom node (OBN) baseline project by Equinor. The two-month survey covers the Krafla, Askja and Sentral fields in the Norwegian North Sea.

More than 7,000 nodes, using an ocean bottom “nodes-on-a-rope” system, will be utilised for the 363 sqkm receiver area survey. This will be the largest project of its type performed by Shearwater to date. The survey will be conducted by the vessels SW Vespucci, SW Cook and SW Tasman with start-up early in the summer of 2022.

“Ocean bottom node projects provide our clients with an excellent baseline for future 4D time-lapse monitoring to help optimise oil and gas production over time, as well as providing advanced images for improved development planning,” said Irene Waage Basili, CEO of Shearwater. “Our scale, the flexibility of our fleet and its unique technical capabilities position Shearwater to execute major value-adding projects for our clients while at the same time maximising own fleet utilisation.”

The SW Vespucci, SW Cook and SW Tasman are highly flexible seismic vessels, capable of multiple applications including source, streamer surveys, and ocean bottom receiver deployment. The flexibility allows Shearwater to address a diverse range of projects safely and efficiently in succession while also delivering technical excellence.
