CGG, in association with Côte d’Ivoire's Direction Générale des Hydrocarbures (DGH) and PETROCI Holding, has announced two new multi-client 3D reimaging programmes, CDI24 Phase I (3,120 sq km) and Phase II (6,610 sq km)

Both projects are supported by the industry, with Phase I commencing immediately and Phase II planned for H1 2025.

These new programmes will be merged with the CDI23 (6,430 sq km) reimaged data (originally marketed as 2023/2024 PDSM), to create a seamless and contiguous total volume of over 16,000 sq km, overlapping the recently announced Calao discovery and adjacent to the world-class Baleine field.

Drawing on more than 90 years of geoscience expertise, CGG is utilising its latest proprietary imaging technologies and highly specialised high-performance computing to provide the best possible results from legacy 3D seismic to support exploration offshore Côte d'Ivoire. These cutting-edge tools, including time-lag FWI, Q-FWI, Q-Kirchhoff and advanced deghosting and demultiple techniques, aim to produce clearer images of the deep structural plays not visible in the legacy data, as well as imaging the Calao Cenomanian and Baleine Carbonate fairways at unrivalled resolution, providing a step-change in understanding of the opportunities in the region.

Dechun Lin, executive vice-president - earth data, CGG, said, “CGG is supporting the energy industry by using innovative imaging technology to create new value from existing seismic data in the region. These premium reimaged data sets will provide an all-encompassing and highly accurate view of Côte d'Ivoire's potential, empowering the industry to de-risk future exploration and unlock new energy reserves confidently.”
