MASSY, France — CGG (rebranding soon as Viridien) has started two new multiclient 3D imaging programs offshore Côte d’Ivoire in partnership with the country’s Direction Générale des Hydrocarbures (DGH) and state energy company PETROCI.
CDI24 Phase I, covering a 3,120 sq km area, is underway while Phase II (6,610 sq km) should begin during the first half of 2025.
Both will be merged with the CDI23 (6,430 sq km) reimaged data, which was originally marketed as 2023/2024 PDSM, to create a contiguous total volume of more than 16,000 sq km. The area overlaps Eni’s recent Calao discovery and is also adjacent to the company’s deepwater producing Baleine Field.
CGG is applying its latest imaging techniques and high-performance computing to the legacy 3D seismic to support future exploration offshore Côte d'Ivoire. Tools used include time-lag FWI, Q-FWI, Q-Kirchhoff, and advanced deghosting and demultiple techniques.
The overall goal is to generate clearer images of the deep structural plays not visible in the legacy data, and to image the Calao Cenomanian and Baleine Carbonate fairways with higher resolution.
