TGS changing Infrastructure Lead Exploration (ILX) in the North Sea

TGS has more than 40 years of experience in the acquisition and processing of seismic data in the North Sea. The basin-wise North Sea Renaissance (NSR) survey set the standard for recorded offsets and use of AVO for identifying and de-risking prospects. In 2018-2019 TGS broke new ground with the world’s largest multi-client Ocean Bottom Node (OBN) survey - Utsira OBN, a joint venture with AGS - offering densely sampled, full azimuth and ultra-long offset data for near-field exploration in a mature area of the North Sea. TGS is expanding the OBN coverage with the NOAKA OBN in 2021.

Data Coverage & Projects

Since the first 2D survey in 1981 and 3D survey in 2000, TGS has built the industry’s largest portfolio of modern regional 2D and 3D coverage in the North Sea. Key projects include the NVG/SVG (a JV with PGS), ZCD, and the Utsira and NOAKA OBN surveys.
