Operations on the Bergen Surveyor

The versatile P-Cable™ 3D Seismic System benefits operations in mature as well as frontier regions. Providing proven Hi-Res 3D data for exploration and field development.

Through our partners we also provide post-processing services with de-multiple removal for selected targets. The benefits of P-Cable’s new technology includes the ability to produce low cost high-resolution 3D seismic data with rapid deployment and retrieval from small vessels, as well as high production rates and the ability to acquire data in shallow waters. WGP recently acquired a set of multi-client data in the Barents sea in conjunction with TGS.
