TGS Announces NOAKA Ocean Bottom Node Seismic Survey on the Norwegian Continental Shelf

OSLO, Norway (2 August 2021) - TGS, a global provider of energy data and intelligence, today announced a new Ocean Bottom Node (OBN) seismic survey on the Norwegian Continental Shelf (NCS).

The 437 square kilometer survey will be acquired in the NOAKA area, between Oseberg and Alvheim in the Norwegian North Sea, containing both held and open acreage. This region has seen significant Infrastructure-Led Exploration (ILX) activity in recent years and includes the development of the NOAKA fields, one of the largest developments on the NCS, with recoverable reserves of more than 500 million barrels of oil equivalents.

TGS expects to emulate the recent success of the TGS-AGS Utsira OBN project in the North Sea (the first large-scale, densely sampled OBN survey for exploration) and will apply the learnings from TGS’ ongoing reprocessing of Utsira, including the extraction and use of ultra-long offset signal for FWI-based model building. As with Utsira, the NOAKA survey will utilize full azimuth and ultra-long offsets to understand and illuminate the complex geology in the region. In addition, it will make use of multicomponent processing leading to stable low frequencies, high signal-to-noise ratios, reliable AVO and the ability to distinguish between structure and attribute anomalies.

Kristian Johansen, CEO at TGS, stated: "TGS remains committed to further advance its position as a leading provider of OBN technology to the energy industry. We continue to focus on areas, such as U.S. GOM and the North Sea, where the enhanced insight from this method can generate economically attractive new exploration opportunities for our clients”.

Acquisition is expected to commence in Q3 2021 with final processing deliverables expected in Q3 2022. Revenues are expected to be recognized in Q4 2021.
