TGS has signed a strategic agreement with Equatorial Guinea to drive the development of seismic and geophysical data in its offshore basins, consolidating a new phase in the country’s energy exploration.
The agreement covers data acquisition, processing, and reprocessing, as well as its promotion to international operators. This comprehensive approach positions Equatorial Guinea as a more competitive destination on the global offshore exploration map.
A central element is the advanced reuse of historical seismic data, some sourced from original field tapes, which will be reinterpreted using modern technologies to extract information that was previously inaccessible.
Seismic reprocessing: the true hidden value
One of the pillars of the agreement is the reinterpretation of datasets acquired at different times. Thanks to new imaging techniques, TGS can significantly improve subsurface resolution without the need to acquire entirely new data.
This approach reduces exploration costs and, at the same time, decreases geological uncertainty, a critical factor in investment decision-making in exploration and production (E&P).
In addition, the “MegaStudy” concept will make it possible to integrate local, regional, and basin data into a single coherent framework, enabling more accurate evaluations of prospects and petroleum systems.
GeoStreamer and broadband redefine subsurface imaging
The agreement also includes the acquisition of new seismic data using GeoStreamer technology, a broadband multisensor solution that significantly improves the quality of subsurface images.
This technology enables high-fidelity data to be obtained at multiple depths, optimizing reservoir characterization and facilitating dynamic field monitoring.
The technical impact is clear: improved seismic resolution means greater accuracy in identifying structural and stratigraphic traps, reducing risks in exploratory drilling.
Risk reduction in major African basins
At the regional level, the initiative will have a direct impact on strategic basins such as Rio del Rey and Rio Muni, where data integration will enable a more robust analysis of complex petroleum systems.
The creation of continuous, integrated datasets will facilitate advanced exploration studies, increasing the probability of success and optimizing the planning of offshore campaigns.
Overall, this alliance strengthens TGS’s role as a large-scale strategic driver in the digital transformation of energy exploration, demonstrating that true value is no longer only in acquiring data, but in reinterpreting it with intelligence and state-of-the-art technology.
