TGS wins contract in Europe for 2025 summer season

Norway-based energy data and intelligence company TGS has secured its first 3D streamer contract for the 2025 summer season, set to be performed in Northwest Europe.

According to TGS CEO Kristian Johansen, the company is experiencing higher bidding activity for this region compared to recent years, and while most of its streamer acquisition programs in Northwest Europe were multi-client in 2024, this trend will likely be reversed in 2025 with an overweight of contract work.

The acquisition is scheduled to commence in May with a total duration of approximately 35 days.

“We are very pleased to secure our first streamer contract job for the 2025 summer season. Award of this program underscores our strong position in Northwest Europe,” Johansen said.

“The planned activity increase in the Northwest Europe region mirrors the global demand increase we experience for our services scheduled for first half 2025. We look forward to supporting our client’s exploration efforts with our proven GeoStreamer technology and Ramform acquisition platform.”

The news about the award came ten days after TGS had announced the enhancement of its Fusion 3D seismic dataset offshore Sierra Leone, focusing on the Vega prospect, a reprocessing project that is said to leverage advanced seismic imaging workflows to enhance depth data, offering clearer subsurface insights for oil & gas companies exploring the area.

The reprocessing project includes approximately 7,500 square kilometers of 3D seismic data, complemented by 16,000 line kilometers of 2D pre-stack depth migrated (PSDM) data, and supported by gravity, magnetic, and interpretive data products. Final results are expected in Q3 2025.

“Sierra Leone has all the geological ingredients to emerge as a leading exploration frontier in Africa. With accessible acreage, attractive fiscal terms, and this depth-migrated high-quality Fusion 3D data, the exploration potential is strong,” said David Hajovsky, Executive Vice President of Multi-Client at TGS.

“TGS is committed to supporting Sierra Leone’s energy sector development, and this initiative will promote investment and reinforce Sierra Leone’s standing as an emerging player in the global energy market, working closely with PDSL (Petroleum Directorate of Sierra Leone) and other stakeholders to maximize the benefits of this initiative for all parties involved.”

Last month, TGS reported the availability of fast-track data from the Nefertiti Multi-Client 3D seismic survey conducted in partnership with the Egyptian Natural Gas Holding Company (EGAS), which expanded 3D GeoStreamer data coverage to further understand the potential in the shelf and transform margin domains in the western part of Egypt’s Mediterranean offshore area.

The survey is situated near the Sidi Barrani-1 well in the far west of Egypt’s offshore Mediterranean and covers shallow to medium water depths within the shelf and transform margin domains.
