TGS Launches First Angola Ultra Deepwater 2D Seismic Survey in Over a Decade
Event summary
- TGS ASA begins Ultra Profundo multi-client 2D survey offshore Angola, covering ~12,600 line kilometers.
- Ramform Victory vessel commenced operations in Q1 2026; data acquisition expected to take ~100 days.
- Fast-track seismic products available by Q3 2026; full processing completes in Q2 2027.
- Survey targets underexplored ultra deepwater areas with focus on pre-salt and sub-salt structures.
The big picture
TGS' Ultra Profundo survey addresses a critical data gap in Angola's ultra deepwater frontier, an area with significant but underexplored hydrocarbon potential. The initiative comes as energy companies seek to balance exploration of new resources with the global shift toward lower-carbon solutions. Success here could position TGS as a key enabler for future Angolan offshore development.
