en.Wedoany.com Reported - Norwegian energy data and intelligence company TGS has signed an agreement with the Ministry of Hydrocarbons and Mining Development of the Republic of Equatorial Guinea to deliver a large-scale multi-client seismic data product covering the country's offshore basins. The first phase of this MegaSurvey is expected to be completed in the third quarter of 2026 and will include approximately 27,273 kilometers of 2D seismic data post-stack reprocessing and about 35,000 square kilometers of 3D seismic data. This is the first phase of a broader plan, with the ultimate goal of creating a unified and seamless seismic data product across Equatorial Guinea's offshore basins. The complete product will cover approximately 46,343 line kilometers of 2D seismic data and over 59,000 square kilometers of 3D seismic data.

TGS describes the MegaSurvey as a unified 3D seismic dataset covering a large, continuous area, designed to support more reliable geological interpretations, improve understanding of structural and stratigraphic frameworks, and help reduce exploration uncertainties.

David Hajovsky, Executive Vice President of TGS Multi-Client Business, stated that the Equatorial Guinea MegaSurvey is the first project of its kind in the country. It will apply TGS's latest imaging technologies to address key subsurface challenges and support reducing exploration risks in the Rio del Rey and Rio Muni basins. The product aims to provide clients with a basin-wide regional screening tool, supporting prospect identification, prospect ranking, and future work commitment planning. By integrating and reprocessing historical datasets into a consistent regional framework, the MegaSurvey can offer insights into the exploration potential of Equatorial Guinea's offshore basins, supporting informed exploration decisions. The company emphasized that the project is not limited by the geographical boundaries of the basins, and this agreement supports TGS's long-term goal of establishing a broader, seamless regional data product in the Gulf of Guinea. Recently, TGS has also secured several new deals, including offshore wind farm site characterization contracts in Europe.
