Viridien Launches CDI25, a 6,555 km² Seismic Reimaging Project in Côte d'Ivoire
Viridien announces the start of the CDI25 project, a seismic reimaging program covering 6,555 km² in the Tano Basin, Côte d'Ivoire. This initiative is part of a broader strategy to modernize seismic data that has been underway for four years.
A Multi-Year Seismic Reimaging Program of the Tano Basin
The CDI25 project aims to produce a multi-client seismic data set usable for exploration by applying advanced processing and imaging technologies. Viridien is notably utilizing Ghost Wavefield Elimination (GWE) technology, multiple attenuation techniques, and the Time-Lag Full-Waveform Inversion (TL-FWI) method to enhance bandwidth, strengthen deep imaging, and refine structural and stratigraphic details.
This project is part of a seismic reimaging program of the Tano Basin initiated four years ago, designed to systematically modernize seismic data and enhance interpretative confidence across the basin.
Coverage and Deliverables of the Program
Upon completion of CDI25, the overall seismic reimaging program will constitute a continuous 3D seismic volume covering over 16,000 km² of the Tano Basin. This coverage enhances the assessment of exploratory potential and understanding of oil plays, particularly providing data on the Calao Channel complex (including the recent Murene South discovery) and extending the regional context to the adjacent Baleine field to support the maturation of prospects and exploratory delineation.
Preliminary results of the project are expected in the fourth quarter of 2026, with final deliverables by the second quarter of 2027.
