TGS, PGS in Barents Sea 3D seismic survey (Norway)

Two Norwegian seismic companies TGS and PGS have announced a new multi-client project in the Barents Sea, offshore Norway, labeled the Nansen 3D Geostreamer.

The survey will cover around 6100 square kilometers in an active APA area of the Hammerfest Basin. The acquisition is expected to start in late May and is due to be completed in September 2018.

According to a statement on Tuesday, 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.

Kristian Johansen, CEO, TGS:”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

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).

Data processing will be performed by TGS using its Clari-Fi(TM) broadband technology. Fast-track data will be available in Q1 2019 with final data in Q4, TGS said.
