Shearwater wins 4D ocean bottom node project in Norway from Equinor

Shearwater GeoServices said that it has won a 4D ocean bottom node (OBN) baseline project from Norwegian oil and gas giant Equinor.

The 4D ocean bottom node survey, which is for a couple of months, will cover the Krafla, Askja, and Sentral fields located in the Norwegian part of the North Sea.

According to Shearwater GeoServices, over 7,000 nodes, using an ocean bottom “nodes-on-a-rope” system, will be used for the receiver area survey that will cover 363sqkm. This will be the largest project of its type so far to be carried out by the Norwegian seismic exploration company.

Shearwater GeoServices will carry out the 4D ocean bottom node survey by the SW Vespucci, SW Cook, and SW Tasman vessels with start-up expected early in the summer of this year. The three flexible seismic vessels are said to be capable of being used for multiple applications such as source, streamer surveys, and ocean bottom receiver deployment.

Irene Waage Basili — CEO of Shearwater GeoServices said: “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.

“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.”
