Côte d’Ivoire, Tano Basin

Unlock the depths of the Tano Basin with CGG’s high-quality 3D seismic

Côte d’Ivoire is becoming a hotspot for oil and gas exploration. Recent discoveries, favorable geological conditions, and government support make it an attractive destination for energy companies. The ongoing exploration efforts point to a promising future for hydrocarbon development in the country. CGG’s advanced 3D seismic dataset is your gateway to revealing the area's full potential.

New and enhanced seismic data

CGG is currently undertaking PSDM reimaging of over 6,400 km2 of seismic data, starting from field tapes and using its latest proprietary technologies. The fast-track volume, completed in March 2024, already shows a significant uplift compared to the legacy data. The final products will be available by the end of 2024, and this state-of-the-art data will present an unprecedented opportunity to reveal further prospectivity that the new carbonate and proven clastic plays hold in the Ivorian side of the Tano Basin.

Building on the early success of our current reimaging project CDI23, CGG, in association with Côte d’Ivoire's Direction Générale des Hydrocarbures (DGH) and PETROCI Holding (PETROCI), is pleased to announce two new multi-client 3D reimaging programs, CDI24 Phase I (3,120 km2) and Phase II (6,610 km2). Both projects are supported by the industry, with Phase I commencing immediately and Phase II planned for H1 2025.

CGG is utilizing its latest proprietary imaging technologies to create a seamless and contiguous total volume of over 16,000 km2, overlapping the recently announced Calao discovery and adjacent to the world-class Baleine field. The aim is to provide the best possible results from legacy 3D seismic to support exploration offshore Côte d'Ivoire.


  • Extensive coverage: three ongoing multi-client 3D reimaging programs merged to create a seamless and contiguous volume of over 16,000 km2, covering the recent Calao discovery and adjacent to the renowned Baleine field
  • Unrivaled detail: full-bandwidth data for high-resolution imaging targeting the Cretaceous reservoir intervals
  • Additional final data available now: 4,400 km2 of 3D BroadSeis™ BroadSource™ data acquired and processed by CGG in 2014 over the CI-709 and CI-710 blocks, producing full-bandwidth data for high-resolution imaging
  • Gravity and magnetic datasets also available
