Reprocessing campaign in Rio Muni offshore Equatorial Guinea

Following exploration successes from the Zafiro, Asen/Aleng and Ceiba/Okume fields in Equatorial Guinea, the Ministry of Hydrocarbons and Mining Development has now initiated a comprehensive reprocessing campaign in Rio Muni basin, which is anticipated to possess excellent geological promise

A survey over 9,600 sq km of the largely underexplored basin has been launched by Geoex MCG, in partnership with Perceptum and DUG Technology and the Ministry of Hydrocarbons and Mining Development.

Once the results of the reprocessing are out around Q4 2026, interpreters can enjoy the fruits of modern data and full waveform inversion (FWI) workflows, gaining influential insights from enhanced quality images. 

To target areas potentially eligible for exploration development, key down-dip plays within the Miocene and Upper Cretaceous–Paleogene intervals will be put to reprocessing. The L-1 and L-2 wells will be tied for attaining velocity and depth control. 

Equatorial Guinea, including offshore Sao Tome and Principe as per the Jaca well, is known to be rich in reservoir and source sequences, and the reprocessing team will be hunting for the entry points to especially access potential source rock presence in these regions. An in-depth understanding of the tectonic history will help delineate the largely coveted distal petroleum systems which holds the promise of vast volumes. The reprocessing will generate advanced images of high-resolution delineation of aged intervals in the region.
