Energy data and intelligence provider TGS has secured a second ocean bottom node (OBN) contract in Europe, strengthening its offshore seismic acquisition pipeline for the 2026 European season.
The latest award follows TGS’ first European OBN contract announced in December 2025, signaling growing regional demand for high-quality seabed seismic data.
Node-on-a-Rope System to Mobilize Mid-Summer
Under the new contract, TGS’ node-on-a-rope crew is scheduled to mobilize in mid-summer, with acquisition activities expected to run for approximately 30 days.
While the client name and contract value have not been disclosed, TGS confirmed that the award comes from a repeat customer, reflecting continued confidence in the company’s OBN technology and delivery performance.
Building a Scalable European OBN Campaign
The second award allows TGS to expand its OBN footprint in Europe, moving toward a multi-project acquisition campaign rather than single, standalone surveys.
Kristian Johansen, CEO of TGS, commented:
“We are very pleased to secure further OBN work for the 2026 Europe season. We are now building an acquisition campaign in the region that we expect will grow further.”
He added that the repeat award highlights the strength of TGS’ technical offering and execution capability.
Enabling High-Quality 4D Seismic Insights
According to TGS, the project will leverage its OBN technology to deliver high-quality 4D seismic data, supporting operators in:
- Reservoir monitoring
- Production optimization
- Improved field management decisions
Johansen emphasized the value delivered to clients:
“The award is from a valued repeat customer who recognizes the strength of our OBN technology, our proven track record and our ability to deliver high-quality 4D data on time, providing critical insights that help the customer optimize oil and gas production.”
What This Means for Seismic and Subsurface Talent
From a technology and recruitment perspective, expanding OBN activity in Europe continues to drive demand for specialists across:
- OBN and seabed seismic acquisition
- 4D seismic processing and interpretation
- Offshore survey operations and HSE
- Subsurface data integration and reservoir analytics
As operators increasingly rely on time-lapse seismic to extend field life and improve recovery, OBN campaigns remain a critical component of offshore subsurface strategies.
Blog Summary
TGS has secured a second ocean bottom node (OBN) contract in Europe for the 2026 season, following an earlier award announced in December 2025. The project will deploy TGS’ node-on-a-rope system for a 30-day acquisition campaign, reinforcing growing demand for high-quality 4D seismic data to support offshore oil and gas production optimization.
Frequently Asked Questions
1. What is an OBN survey?
Ocean Bottom Node (OBN) surveys use seismic sensors placed on the seabed to acquire high-resolution subsurface data.
2. When will the project start?
Mobilization is planned for mid-summer, with operations lasting around 30 days.
3. Who is the client?
The client has not been disclosed but is described as a repeat customer.
4. Why are OBN surveys important?
They deliver high-quality 4D seismic data used for reservoir monitoring and production optimization.
5. Is this TGS’ first OBN project in Europe?
No. This is the second European OBN contract for the 2026 season, following an award announced in December 2025.
