Hajovsky’s participation comes amid a significant expansion of TGS’ activities in Angola. The company is currently acquiring and processing new, modern 2D and 3D seismic datasets while concurrently reprocessing more than 45,000 km² of legacy 3D coverage. Final deliverables are expected in the coming months. Together, the two seismic projects aim to expand proven fairways while identifying new prospectivity in underexplored areas and frontier margins, particularly across the Lower Congo Basin.

These initiatives build on TGS’ expanded coverage across the basin. In 2025, the company acquired a multi-vessel, one-sided Wide-Azimuth survey across Blocks 33, 49 and 50. Another project, Angola Vision, is approaching completion, offering reprocessed legacy seismic data across Blocks 33 and 34.

Beyond the Lower Congo, TGS is working to improve seismic insights across other promising offshore basins, including Kwanza and Benguela. In partnership with the National Oil, Gas & Biofuels Agency, TGS has been acquiring and processing multi-client 3D and 2D seismic data in the country for more than 20 years. This has resulted in a library comprising 69,200 km² of 3D data and more than 50,000 line-km of 2D data.

Through its Kwanza Vision project, the company is applying modern depth reprocessing to 26,300 km² of GeoStreamer data, improving subsurface imaging across a basin where the $6 billion Kaminho development has already demonstrated commercial potential. TGS also recently acquired the Ultra Profundo 2D survey, encompassing approximately 17,150 line-km of long-offset data along the Angolan margin and traversing the Lower Congo and Namibe Basins. Final processed data is expected in 2027.

Meanwhile, in June 2026, the company was awarded a 4D streamer contract offshore Angola. The contract runs for eight months, commencing in July 2026.

This expanding data inventory aligns closely with Angola’s wider effort to stimulate another cycle of exploration. Regulatory and fiscal reforms, new acreage opportunities, and incentives for marginal discoveries and gas development have brought international companies back to frontier areas, including the Namibe and northern Kwanza Basins. Better subsurface data will be critical to converting that renewed interest into drilling campaigns and, ultimately, discoveries.

TGS will bring this technical and investment perspective directly to discussions in Luanda. Hajovsky’s participation at AOG 2026 will highlight how next-generation seismic acquisition, reprocessing and subsurface intelligence can reduce exploration uncertainty, extend established plays and help open new petroleum provinces as Angola targets its next generation of offshore resources.

AOG 2026 takes place September 9-10, with a pre-conference day scheduled for September 8. Visit www.angolaoilandgas.com for more information.
