Despite hosting some of West Africa’s most productive offshore fields — including Zafiro, Asen/Aleng, and Ceiba/Okume — Equatorial Guinea’s Rio Muni basin has long remained underexplored. A major new initiative aims to change that.
Geoex MCG, in partnership with Perceptum, DUG Technology, and the Ministry of Hydrocarbons and Mining Development (MHMD), has launched a comprehensive seismic reprocessing campaign covering more than 9,600 square kilometres across the Rio Muni basin. Final products are expected in the fourth quarter of 2026.
The initiative will deploy Full Waveform Inversion (FWI) workflows to significantly enhance subsurface imaging quality, delivering modern data that provides interpreters with sharper insight into the basin’s hydrocarbon prospectivity. By tying the L-1 and L-2 wells for velocity and depth control, the reprocessing will focus on key down-dip plays within the Miocene and Upper Cretaceous–Paleogene intervals — geological horizons considered prospective for new hydrocarbon discoveries. The campaign is expected to unlock fresh opportunities for exploration and development in a basin that geologists have long viewed as geologically promising but data-deficient.
