Norway's Shearwater GeoServices has clinched more seismic data work from compatriot charterer TGS.
The project is expected to take three months and is scheduled to be completed by the end of September.
It will take place on the Atlantic Margin in the Norwegian Sea.
The 2018 survey is for 5,135 square km. Last year, Shearwater acquired 29,500 sq km of data for TGS.
