TGS Secures Ocean Bottom Node Survey Contract Ahead of Q4 2026 Launch

## TGS to Launch 100-Day OBN Seismic Project in Q4 2026 Norwegian energy data and intelligence company TGS has secured a contract for an ocean bottom node (OBN) seismic survey project expected to kick off in the fourth quarter of 2026, according to Offshore Energy. The project is scheduled to run for approximately 100 days, underscoring continued industry investment in high-resolution subsurface imaging technology. OBN surveys are widely regarded as delivering superior seismic data quality compared to conventional towed-streamer methods, particularly in complex geological settings and areas with significant infrastructure on the seabed. The technology deploys individual nodes directly on the ocean floor, enabling full-azimuth, wide-offset data acquisition that supports more accurate reservoir characterisation and field development planning. For TGS, the contract represents a further expansion of its multi-client and proprietary survey operations at a time when upstream exploration activity is showing renewed momentum across key offshore basins. The company has been actively broadening its geoscience data offerings as operators seek higher-quality subsurface intelligence to underpin drilling and development decisions. While specific details regarding the survey location and client have not been disclosed, the 100-day duration suggests a substantial scope, likely covering a sizeable acreage block in a frontier or producing offshore region. Further project details are expected to be released closer to the mobilisation date. The announcement reflects broader trends in the offshore energy sector, where demand for advanced seismic acquisition services has strengthened alongside recovering oil prices and increased exploration budgets among international operators. OBN technology in particular has seen growing uptake in deepwater and ultra-deepwater environments where data quality is critical to reducing exploration risk. TGS, headquartered in Oslo, operates one of the world's largest libraries of multi-client geoscience data and has been expanding its capabilities through both organic growth and strategic acquisitions in recent years.
