Angola’s upstream oil sector is entering a new phase in which legacy geological data is being reprocessed using artificial intelligence to unlock fresh exploration potential across its offshore basins.
Operators are now revisiting decades-old seismic datasets and applying advanced AI-driven workflows to improve subsurface imaging and reduce drilling risk in key frontier areas, including the Lower Congo, Kwanza, and Namibe basins. The approach is increasingly central to Angola’s strategy as it seeks to maximise value from existing acreage rather than rely solely on new seismic acquisition.
This trend will be a focal point at African Energy Week (AEW) 2026 in Cape Town, scheduled for October 12–16, where the “Renegade Intel” track will explore the convergence of AI, subsurface analytics, and data infrastructure in upstream energy development.
Since launching a structured licensing regime in 2019, Angola’s National Oil, Gas and Biofuels Agency (ANPG) has awarded 37 blocks and negotiated a total of 64, with 27 still in progress. Much of this acreage is being advanced through reinterpreted seismic data rather than newly acquired surveys, underscoring the shift toward computational exploration.
Data service providers are at the centre of this transformation. TGS has reprocessed around 16,000 km² of 3D seismic data across Kwanza blocks 35, 36, and 37, deploying techniques such as full-waveform inversion, reverse-time migration, and de-ghosting to sharpen imaging beneath complex salt structures.
Meanwhile, Viridien is working across 7,200 km² in the Kwanza and Lower Congo basins and has launched a 4,300 km² multi-client reimaging project over Block 22 to improve understanding of the Atlantic Hinge zone.
In the frontier Namibe Basin, ExxonMobil is leading exploration across blocks 30, 44, and 45. The company drilled the Arcturus-1 well in 2024 and has indicated potential investments of up to $15 billion through 2030, contingent on commercial success. Such large-scale programs depend heavily on high-performance computing, as seismic processing demands scale exponentially with resolution.
Onshore, similar data-driven approaches are emerging. Corcel recently completed a 2D seismic programme in Block KON-16 in the Kwanza Basin, integrating historical and modern datasets to significantly expand subsurface coverage.
Supporting this shift, SLB opened its Africa Performance Centre in Luanda in 2025, providing operators access to AI tools and digital workflows while also strengthening local technical capacity.
As Angola deepens its data-led exploration model, competitive advantage is increasingly defined by computing infrastructure, AI capability, and geoscience expertise, an evolution expected to dominate discussions at AEW 2026’s Renegade Intel track.
