ASKER -- TGS and Petroleum Geo-Services (PGS) announce a new multi-client project in the Barents Sea. The new Nansen 3D Geostreamer survey will cover ~6,100 km² in an active APA area of the Hammerfest basin. Acquisition is expected to commence late May and is due to be completed in September 2018.

The project is designed to improve the imaging of the known fields and discoveries, and allow identification and development of new targets in both mature and new plays. The survey area contains shallow targets on the basin flanks and platforms, with deeper exploration potential elsewhere in the basin.

"Nansen 3D will expand TGS' data coverage in the Barents Sea, where we have a strong track record of success. This project will provide modern, high-quality seismic data to an area that is highly relevant for exploration in the current and upcoming APA rounds," said Kristian Johansen, CEO, TGS.

PGS' Ramform Atlas will tow an ultra-high-density 3D configuration with a 16 x 56.25 m x 7,000 m setup. Three of the streamers are towed with 10 km offsets for optimized performance of full waveform inversion (FWI). The acquisition design is tailored to fully utilize the potential of an advanced PSDM and FWI processing workflow.

Data processing will be performed by TGS using its Clari-Fi broadband technology. Fast-track data will be available in first-quarter 2019 with final data in fourth-quarter.
