ASKER, Norway – TGS and Petroleum Geo-Services (PGS) have announced a new multi-client project in the Barents Sea.
The Nansen 3D Geostreamer survey will cover ~6,100 sq km (2,355 sq mi) in an active APA area of the Hammerfest basin. Acquisition is expected to begin this month and is due to be completed in September 2018.
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 (6.2 mi) offsets for optimized performance of full waveform inversion (FWI). The acquisition design is said to be 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. Fasttrack data will be available in 1Q 2019 with final data in 4Q.
TGS CEO Kristian Johansen said: “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.”
