Summary
A 3D multiclient seismic survey was recently acquired and processed in a frontier exploration area offshore Angola, spanning blocks 33, 49, and 50 and covering 8,726 km². To address the subsurface challenges associated with complex salt tectonics, the project combined advanced acquisition technologies—such as multi-sensor streamers and enhanced frequency sources—with a one‑sided wide‑azimuth (WAZ) streamer configuration and employed state-of-the-art model building techniques such as elastic Full Waveform Inversion (FWI).
