The National Oil Company of Liberia (NOCAL) has welcomed the launch of the Sunfish 3D seismic reprocessing project by global geoscience firm TGS, describing it as a significant step.
The project, which spans approximately 6,100 square kilometers in the Harper Basin, is designed to enhance geological interpretation through advanced seismic imaging.
According to NOCAL, the initiative will provide a clearer and more detailed view of subsurface structures, improving the identification and evaluation of offshore hydrocarbon prospects.
In a statement shared through its official communication channels, NOCAL explained that the reprocessing will apply state-of-the-art 3D Kirchhoff Pre-Stack Depth Migration technology.
The approach is expected to deliver higher-resolution imaging of Upper Cretaceous formations while preserving Amplitude Versus Offset (AVO) responses, a critical factor in accurate reservoir analysis.
Officials said the upgraded data will enable exploration companies and potential investors to conduct more reliable subsurface assessments, reduce geological uncertainty, and unlock new opportunities within Liberia’s offshore basins.
The Sunfish project is scheduled for completion in the third quarter of 2026 and forms part of a broader partnership between NOCAL and TGS aimed at modernizing Liberia’s national seismic data repository.
Upon completion, the collaboration will have reprocessed all available offshore seismic data, covering more than 50,000 kilometers of 2D data and over 31,000 square kilometers of 3D data using advanced imaging technologies.
NOCAL views the initiative as a key milestone in positioning Liberia as a data-ready and competitive destination for offshore energy investment.
The company said the effort underscores Liberia’s commitment to transparency, technical excellence, and the development of a modern petroleum sector aligned with international best practices.
