As seismic surveys generate ever-larger datasets, the ability to move information quickly from offshore vessels to onshore processing centers has become a defining constraint in exploration. A collaboration between TGS and Starlink is now removing that bottleneck – reshaping how seismic data is acquired, transmitted and processed across the energy sector.
Traditionally, offshore seismic data was stored onboard and physically shipped to onshore facilities, creating delays of days or even weeks before processing could begin. This approach also introduced duplication risks, logistical complexity and delayed decision-making at critical stages of exploration.
TGS has spent the past several years redesigning this workflow, transitioning to a cloud-native model, where data flows directly from sensor to client. Central to this shift is the integration of Low Earth Orbit (LEO) satellite connectivity – specifically Starlink – which enables near real-time transmission of high-volume seismic datasets. Field trials conducted by TGS show that full-integrity seismic data can be transmitted directly to the cloud using LEO satellites, reducing delivery times from an average of nine days to just one. This eliminates the need for physical transfer entirely, allowing processing, quality control and interpretation to begin almost immediately.
The technological leap is rooted in Starlink’s architecture. Unlike traditional geostationary satellites, which suffer from high latency and limited bandwidth, LEO constellations operate much closer to Earth, delivering significantly faster speeds and lower latency. In offshore environments, this enables high-throughput data transfer, real-time monitoring and seamless integration with cloud platforms – capabilities previously unattainable at scale.
For seismic acquisition, the implications are substantial. Near real-time data transfer allows onshore teams to monitor surveys as they happen, adjust parameters dynamically and accelerate decision-making. It also reduces reliance on heavy onboard computing infrastructure by shifting processing to scalable cloud environments. Combined with TGS’ use of cloud and AI-driven analytics, this significantly enhances compute capacity while shortening project timelines. Beyond operational efficiency, the transformation is also reshaping commercial models. With seismic data increasingly accessible via cloud platforms and APIs, clients can interact with datasets in near real time – enabling faster exploration decisions and more flexible data access.
These capabilities are already being demonstrated in Africa. Starlink is documenting deployments across the energy sector, including a case study with Heirs Energies, Africa’s largest indigenous energy company. Operating in the connectivity-constrained Niger Delta, the company faced persistent disruptions to real-time data flow due to unreliable LTE networks. To address this, it deployed an off-grid, solar-powered IoT system built around Starlink across 21 wellhead sites. The result is continuous remote monitoring and control of assets, with around 90% of site traffic now running through Starlink. The system enables 24/7 performance tracking, remote diagnostics and automated failover, significantly improving uptime, data visibility and operational responsiveness across field operations.
The TGS–Starlink model underscores the need for a fully integrated data ecosystem – from offshore connectivity to regional data centers capable of handling petabyte-scale seismic datasets. By combining real-time data acquisition with cloud-native processing and localized storage, Africa has an opportunity to leapfrog legacy systems and build a digital-first energy sector. Investments in data centers, cloud infrastructure and connectivity will be essential to capturing this value and retaining greater control over critical energy data.
These trends are taking center stage at African Energy Week 2026 through its AI and Data Center Track, “NexaGrid: Create. Enable. Build Africa’s Finest Data Centers for the Future.” The track will highlight the role of digital infrastructure in energy development and examine how Africa can build the capacity required to store, process and monetize its growing volumes of energy data.
“This is a defining moment for Africa’s energy sector, Let’s face it, this solves a huge problem when it comes to transporting key data. No more issues like custom or border officials risking the integrity of the seismic data.” says NJ Ayuk, Executive Chairman of the African Energy Chamber. “As data becomes the backbone of exploration and development, the ability to capture, transfer and process information in real time will determine competitiveness. Africa must invest in the infrastructure that enables this shift. TGS and Starlink are providing an amazing solution for Africa’s energy industry”
Ultimately, the convergence of LEO satellite connectivity, cloud computing and advanced analytics is transforming seismic workflows from a linear, delayed process into a continuous, real-time system. For TGS – and for emerging energy markets across Africa – this is not just an operational upgrade, but the foundation of a new, data-driven energy future.
