Viridien launches next phase of Côte d’Ivoire Reimaging in Tano Basin with CDI25 project

CDI25 is part of a larger Côte d’Ivoire subsurface reimaging programme that Viridien began four years ago, designed to systematically upgrade seismic data and interpretation confidence across the basin. The programme is applying Viridien’s processing and imaging workflows, including Ghost Wavefield Elimination (GWE), advanced de-multiple, and industry-leading Time-Lag Full-Waveform Inversion (TL-FWI), to improve bandwidth, enhance deep imaging, and sharpen structural and stratigraphic detail.

Fast-track CDI25 results are scheduled for 4Q26 and final deliverables by 2Q27. Upon completion of this latest project, the overall reimaging program will deliver a seamless, basin-scale 3D seismic volume providing over 16 000 km² of coverage across the Tano Basin. The integrated dataset will significantly enhance prospectivity assessment and play understanding, providing critical subsurface insight into the recent discovery within the Calao Channel complex, while extending regional context into the adjacent acreage of the Baleine field to support lead maturation, de-risking, and further exploration delineation.

Dechun Lin, Head of Earth Data, Viridien, said: “The recent Murene South and Baleine field discoveries highlight the growing importance of Tano Basin and the industry value of our multi-year reimaging programme. Viridien is proud to support exploration offshore Côte d’Ivoire with cutting-edge data that is generating new insights to reveal further opportunities in this prolific basin.”
