OSLO, Norway (10 June 2024) – TGS, a global leader in energy data and intelligence, has partnered with the National Oil Company of Liberia (NOCAL) to undertake significant additional multi-client seismic data reprocessing offshore Liberia.

This initiative will rejuvenate the remaining 2D and 3D data in Liberia's prospective Liberia and Harper Basins. The project will integrate existing legacy datasets to create a unified velocity model in depth, utilizing cutting-edge imaging algorithms to produce the final migrated seismic data. This enhanced data will be crucial for prospectivity studies in Liberia's offshore waters. The reprocessed products will benefit exploration through a consistent, continuous data set of several vintages by providing continuous seismic attributes of higher confidence at target levels across the entire margin.

David Hajovsky, Executive Vice President of Global Multi-client at TGS, stated: "At TGS, we are proud of our longstanding and successful partnership with Liberia, which we believe presents considerable offshore hydrocarbon opportunities. This high-quality 2D seismic data will be essential in promoting future licensing rounds offshore Liberia under a direct negotiation approach. It also allows E&P companies to further evaluate exploration opportunities in an under-explored but proven petroleum system adjacent to prolific hydrocarbon provinces."

TGS recently completed the first phase of reprocessing approximately 12,097 kilometers of 2D legacy seismic data offshore Liberia, significantly enhancing subsurface clarity. This data is now available for industry licensing. The second phase has commenced, aiming to reprocess an additional 12,675 line kilometers over the Liberia and Harper Basins, bringing the total to over 24,700 kilometers. Additionally, TGS plans to reprocess approximately 15,616 square kilometers of legacy 3D seismic data in the Liberia Basin.
