Viridien announced the start of the CDI25 seismic project in the Tano Basin, Ivory Coast, an initiative that aims to strengthen offshore exploration in one of the fastest-growing energy zones on the African Atlantic margin. The program will cover 6,555 km² of seismic reconstruction and deliver a multi-client dataset ready for future drilling campaigns.
This project will improve the quality of geological information and broaden the understanding of the subsurface in strategic areas of the Tano basin, which is attracting significant international attention due to recent hydrocarbon discoveries, like Baleine and Murene South
What does the project consist of?
It’s a project of “seismic re-imaging”in which geologists use sound waves (like a giant medical scanner) to see what’s underground or under the sea, especially searching for oil and gas. What the company will do is take old seismic data (like blurry photos of the subsoil) and apply state-of-the-art technology to obtain much sharper and more detailed images.
This will help oil companies find oil or gas more accurately and safely. With these improved “snapshots” they will be able to:
- Identify the best places to drill.
- Reduce risks (avoid drilling dry wells).
- To better understand already discovered deposits, such as the recent ones in Hornbill and Whale (two major oil fields in the area).
Viridien will apply advanced seismic processing and imaging technologies such as Ghost Wave Field Removal (GWE), advanced multi-field removal, and time-delay full waveform inversion (TL-FWI). These tools allow for improved seismic bandwidth, optimized depth imaging, and more accurate structural and stratigraphic detail.
The Tano Basin gains strategic importance in African offshore
Once the comprehensive seismic reconstruction program is complete, the company will have a continuous 3D seismic volume exceeding 16,000 km² in the Tano Basin. The project will also provide key information on the Calao channel complex and extend the regional context to the area near the Baleine field, considered one of Africa’s most significant offshore discoveries in recent years.
According to the company, this new stage will accelerate the maturation of prospects and support future drilling decisions in Ivory Coast and other areas of the Gulf of Guinea.
Viridien strengthens its presence
Dechun Lin, Director of Terrestrial Data at Viridien, highlighted that recent discoveries in Baleine and Murene South demonstrate the growing potential of the Tano Basin and the importance of the seismic reconstruction program driven by the company.
The executive stated that the company seeks to support offshore exploration in Ivory Coast by providing high-quality data capable of generating new geological knowledge and expanding energy exploration opportunities in West Africa.
The company maintains a strategy focused on geoscientific technologies, advanced data processing, and digital solutions applied to natural resources, energy transition and infrastructure
