We Are Energy Data

For over 40 years, TGS has built a strong foundation as a global leader in providing a diverse range of energy data and insights to meet the industry where it’s at and where it’s headed. Our proven technology and innovation, robust business model, and obsession with customer service position us to continue to lead the way in oil and gas opportunities and undertake long-term investments in industries that look to reduce carbon emissions.

Our competitive advantages and core strengths of innovation, people, expertise, quality data, and superior service allow us to provide the right energy data at the right time. We provide our customers with the actionable insights they need to make the best business decisions.

Before taking on investment risks, onshore or offshore, energy companies look for clarity and confidence through subsurface data. TGS geological, geophysical, and engineering data coupled with analytical competencies provide valuable exploration insights, superior imaging of the subsurface, and potential operational challenges ahead of drilling programs or infrastructure development. Our multi-client approach offers ease and flexibility for operators at a substantially lower cost than proprietary models.

Forward-looking, our data supports the development of renewable energy. Leveraging our historical data expertise and coupled with machine learning, compute power, cloud-based applications, and strategic partnerships, we offer the same superior data solutions and insights for new energy investments as we do for oil and gas.

Our Competitive Advantages


TGS does not own acquisition vessels and equipment. Nor do we have seismic crews on the payroll. All data acquisition activity is outsourced, which gives us the flexibility to execute only those projects that meet our investment criteria and align with client goals. We are not influenced by vessel or crew utilization targets. Instead, we only access these resources when needed, and we are free to use the most appropriate vendors and technologies to tackle specific imaging and intelligence challenges. TGS is asset- light, which means low overheads and high stability, regardless of industry cycles.

Quality Processing

While acquisition is outsourced, we process the data in-house. This is how we ensure our customers get the highest quality seismic data. To learn more about our processing services, click here.

ROI Discipline

TGS typically targets projects that will earn sales returns between 2 and 2.5 times the investment. On projects with lower targeted returns, we require high levels of pre-funding to keep the investment attractive. 

Renowned Data Collection

TGS has one of the largest and best performing multi-client data libraries in the world. We utilize this data resource both as an ongoing revenue stream and to leverage unique insight using data analytics techniques. In addition, we are committed to developing platforms to enhance data accessibility and empower business decisions

Active Portfolio Management

The multi-client business is a portfolio business. Some projects may underperform and others exceed expectations. A 3D project is a significant financial undertaking, and TGS has the means to invest in a broad portfolio of projects to balance risks and rewards.

Geographic Diversity

TGS has a truly global data collection with a diverse range of data types to serve the expanding needs of the energy industry. We strive to build and maintain leadership positions around the world. Our oil and gas data covers a wide variety of exploration plays including deepwater, pre-salt geologies, the Arctic and North America onshore. Our New Energy data and solutions support the evolving energy transition efforts across the globe. This diversity gives us significant stability and business continuity in the face of shifting markets, regional economic strain and geopolitical challenges.

Superior Team

Our most important competitive advantage comes from our people. The outstanding work of our team, from data scientists to geoscientists, has made TGS the world’s leading energy data provider. Our people are the reason TGS delivers superior project quality and financial performance, year after year.

Strategic Acquisitions

While most of our growth has been organic, we have also expanded our business through acquisitions. These opportunities have allowed us to add data processing capabilities and new geoscience data types to our library. TGS will also purchase other multi-client libraries when the price is attractive and where we see strong potential returns.
